Introduction: Using the self-regulatory executive function model as a basis, this study explored whether, among substance users, metacognitive beliefs and repetitive negative thinking were associated with impulsiveness., Methods: A total of 100 substance users were recruited. Impulsiveness, metacognitive beliefs, rumination and worry were assessed. Correlation and hierarchal regression analyses were run., Results: Beliefs about the need to control thoughts, lower cognitive self-consciousness and brooding rumination were found to be independent predictors of the total score on impulsiveness in the hierarchical regression analysis. Further regression analyses indicated that motor impulsiveness was predicted by a combination of beliefs about the need to control thoughts and brooding rumination, while non-planning impulsiveness was predicted by beliefs about the need to control thoughts and lower cognitive self-consciousness., Conclusion: Among substance users, higher impulsiveness is associated with the tendency to endorse beliefs about the need to control thoughts and brooding rumination. Among substance users, beliefs about the need to control thoughts and brooding rumination (and potentially cognitive self-consciousness) could be a suitable therapeutic targets to mitigate particularly motor impulsiveness and non-planning impulsiveness., (© 2024 John Wiley & Sons Ltd.)

Suicidal ideation (SI), a risk factor for suicide, is prevalent in internalizing psychopathologies, including depression and anxiety. Rumination and worry are well-studied repetitive negative thinking (RNT) constructs implicated in internalizing psychopathologies. These constructs have shared and distinct characteristics. However, the relationship between rumination and worry and their associations with SI are not fully understood in clinical samples. The present study used correlational and regression analysis to evaluate these relationships as a secondary data analysis in treatment-seeking participants with internalizing psychopathologies in two independent samples (Study 1:n = 143; Study 2:n = 133). Results showed about half of the participants endorsed SI (Study 1:n = 79; Study 2:n = 71). Correlations revealed a significant, positive relationship between rumination and worry. Regression results with SI as the dependent variable showed rumination significantly positively corresponded with SI in both studies. Post-hoc partial correlations controlling for symptom severity (depression, anxiety), worry, and age showed the rumination-SI relationship was maintained in both studies. Findings for worry and SI were inconsistent between studies. Findings indicate rumination, but not worry, could be a stable, unique contributor to SI in internalizing psychopathologies. It may be useful to incorporate RNT into suicide risk assessment for individuals with internalizing conditions., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

People high in depressive or anxious symptom severity show repetitive negative thinking, including worry and rumination. They also show various cognitive phenomena, including probability, cost, and interpretation biases. Since there is conceptual overlap between these cognitive biases and repetitive negative thinking - all involve thinking about potential threats and misfortunes - we wondered whether repetitive negative thinking could account for (mediate) these cognitive biases' associations with depressive and anxious symptom severity. In three studies, conducted in two languages and cultures, cost bias and (in two studies) interpretation bias only predicted symptom severity via worry and repetitive negative thinking; this suggests these biases are actually associated with repetitive negative thinking, rather than with symptoms. In contrast, probability bias showed direct relationships with depressive (all studies) and anxious (two studies) symptom severity, suggesting its relationships with symptoms are partly independent of repetitive negative thinking. These results show the value of studying relationships among the various cognitive features of psychopathology. Furthermore, new interventions which target cognitive biases in depression or anxiety must show that they can improve upon cognitive behavioural therapy, which is already widely available, targets both repetitive negative thinking and probability bias, and is highly effective.

Exposure to nature can enhance mental well-being, making nature-based interventions promising for the treatment and prevention of mental health problems like depression. Given the decreased self-focus and sense of self-diminishment associated with awe, the present study investigated the impact of exposure to awe-evoking nature on two key risk and maintenance factors of depression-repetitive negative thinking (RNT) and dampening of positive feelings-and on subjective happiness. In a randomized controlled trial, we tested the effects of exposure to awe-evoking nature clips through a 1-week intervention, consisting of watching a 1-min clip on a daily basis of either awe-evoking (n high awe = 108) or more mundane nature scenes (n low awe = 105). Before, immediately after (post-intervention) and 1 week after the intervention (follow-up), participants completed self-report scales probing RNT, dampening, and subjective happiness. Results indicated significant decreases in these outcomes at post-intervention and follow-up in both groups. We discuss study limitations, touch upon future research ideas, and reflect upon the role of nature for clinical applications., (© 2024 International Association of Applied Psychology.)

Background: Low optimism and high pessimism have predicted depressive symptoms in several studies, but the associations in the other direction, from depressive symptoms to future optimism and pessimism, have been unexplored. We examined bidirectional associations of optimism and pessimism with depressive symptoms in adulthood., Methods: A population-based sample of 4011 Finnish adults (55 % women) was analyzed with a 15-year prospective follow-up period from age 31 to age 46. Optimism and pessimism were measured with the Life Orientation Test-Revised, and depressive symptoms were measured with the Symptom Checklist-25. Temporal associations were investigated with cross-lagged panel models., Results: According to the model fit indices (RMSEA < 0.04, CFI ≥ 0.97) optimism and pessimism had bidirectional relationships with depressive symptoms: optimism predicted lower depressive symptoms (β = -0.09, p < .001), and depressive symptoms predicted lower optimism (β = -0.10, p < .001) in the follow-up. Also, pessimism predicted higher depressive symptoms (β = 0.08, p < .001), and depressive symptoms predicted higher pessimism (β = 0.09, p < .001) in the follow-up. In the participants with clinically high depressive symptoms at age 31, the predictive associations from optimism and pessimism to depressive symptoms remained, but associations in the other direction were attenuated., Limitations: The follow-up study included only two time points with a 15-year time gap, which does not consider the possible fluctuation in the study variables between the measured times., Conclusion: Dispositional optimism and pessimism may have bidirectional relationships with depressive symptoms in adulthood when the baseline depressive symptoms are below the clinical level., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Background: Chronic Kidney Disease (CKD) patients encounter many obstacles that affect their physical and psychological well-being. The primary objective of the present study was to investigate potential correlates of optimism/pessimism in a sample of patients with CKD, including socio-demographics, body appreciation and disordered eating symptoms. As a secondary objective, we proposed to examine the psychometric properties of an Arabic translation of the Optimism-Pessimism Short Scale-2 (SOP2) before its use in our sample., Methods: A cross-sectional study was carried out between April and May 2023, enrolling 108 participants from three hospitals in Lebanon providing insights into their sociodemographic characteristics, physical activity levels, body appreciation, optimism, pessimism, and eating attitudes., Results: Results indicated that the Arabic-language adaptation of the SOP2 has good reliability coefficients. The two facets of the scale displayed a strong correlation to each other, and highly similar correlations with external study variables (i.e., household crowding index, physical activity, body appreciation, disordered eating), suggesting that the SOP2 can be interpreted as a unidimensional measure for the psychological dispositional optimism as proposed by the developers. Furthermore, findings revealed a strong positive correlation between body appreciation and optimism, suggesting that CKD patients who appreciate their bodies tend to exhibit a more optimistic outlook on life. Conversely, higher body appreciation is associated with lower pessimism, indicating that a positive body image may mitigate feelings of hopelessness and despair in CKD patients., Conclusion: This study contributes to the literature in two ways. First, it offers the Arabic SOP2 as an brief tool to administer, and psychometrically sound instrument that can be useful for clinical and research purposes. Second, it unveils a clear correlation between higher body appreciation and a more optimistic, less pessimistic mindset in patients with CKD., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Hajj-Moussa et al.

Research examining gender differences in perseverative cognition (repetitive, negative, and difficult-to-control thoughts) has focused on depressive rumination and internalizing syndromes. This study examines the transdiagnostic role of depressive rumination, anger rumination, and repetitive negative thinking across gender on internalizing and externalizing symptoms. Utilizing an ethnoracially diverse sample (33% Black, 35% Latinx, 32% White non-Hispanic) of n = 1,187 young adults (49.5% women), we found equivalent instrument functioning across gender for depressive rumination (specifically brooding), anger rumination, and internalizing problems. Differential item functioning was found for repetitive negative thinking and externalizing problems; partial metric and scalar invariance were established for repetitive negative thinking, and partial metric invariance was established for externalizing problems. After accounting for bias in measurement, women engaged in more perseverative cognition, though effects were small for brooding and anger rumination and large for repetitive negative thinking. Different types of perseverations were positively associated with internalizing and externalizing symptoms across gender. Perseverative cognition may be a transdiagnostic mechanism beyond internalizing problems. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Alcohol use disorder (AUD) is a common psychiatric condition with substantial global mortality. Despite extensive research into its pathophysiology, the cognitive predispositions driving alcohol dependence are less understood. This study explores whether biased cognition, specifically traits of optimism and pessimism, predicts susceptibility to alcohol-seeking behaviors using an animal model. Rats were initially tested for judgement bias through Ambiguous Cue Interpretation tests. Those identified as 'optimistic' or 'pessimistic' were further examined for their tendency to escalate alcohol intake using the intermittent access 2-bottle choice (2BC) paradigm. Additionally, we assessed how judgement bias influenced the development of compulsive alcohol-seeking behavior in a Seeking-Taking (ST) and Seeking-Taking Punishment tasks, alcohol-seeking motivation in the Progressive Ratio Schedule of Reinforcement paradigm, the speed of extinction, and reinstatement after abstinence. Neurochemical analyses were conducted to investigate trait-specific differences in neurotransmitter-related gene expression and receptor densities in the brain. We used TaqMan Gene Expression Array Cards to analyze expression levels of genes linked to serotonergic, dopaminergic, glutamatergic, and GABAergic pathways, and alcohol metabolism in various brain regions. Receptor densities for 5-HT 1A , 5-HT 2A , and D 2 were measured using autoradiography analysis. Behaviorally, 'optimistic' rats showed significantly lower alcohol consumption in the 2BC paradigm compared to 'pessimistic' rats. This lowered intake correlated with decreased monoamine oxidase-A (Maoa) expression in the medial prefrontal cortex (mPFC) and increased metabotropic glutamate receptor 2 (Grm2) expression in the amygdala (Amy). Additionally, we observed significant interactions between judgement bias and alcohol intake in the expression of several genes in the mPFC, nucleus accumbens (Nacc), orbitofrontal cortex (OFC), and Amy, as well as in 5-HT 2A receptor binding in the Nacc. Overall, these results suggest that optimism is linked to lower alcohol consumption and related neurochemical changes, indicating a potential cognitive mechanism in AUD risk., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

In this study, we examined the relationship between optimism and pessimism associated with the Covid-19 pandemic, mental health, and perceived risk of infection. In particular, we tested the hypothesis that, when optimism and pessimism were high during the pandemic period, a worse mental health and a higher perception of risk would be reported. To this end, a convenience sample of 374 Italian adults was enrolled. Measures included perceived stress, optimism, and pessimism associated with the development of the pandemic situation, as well as the perceived risk of Covid-19 infection. The results showed that optimism and pessimism were associated with perceived stress and Covid-19 risk perception while controlling for demographic variables. Optimism and stress were negatively related, while pessimism was positively related to both stress and risk perception. Furthermore, the interaction between optimism and optimism was significant, with a higher perception of risk in the presence of both high optimism and pessimism, and a lower perception of risk with high optimism and low pessimism. These results support the hypothesis that optimism and pessimism interacted in predicting Covid-19 risk perception and show that they should be measured as partially correlated but independent constructs in future investigations., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Repetitive negative thinking (RNT) is a transdiagnostic process involving perseverative, unproductive, and uncontrollable thoughts. Although RNT may impede adaptive psychosocial functioning by prolonging negative mood states, strengthening cognitive biases, and preventing effective problem-solving, the extent to which RNT is associated with risk for poor psychosocial outcomes is unclear. Given that this has clear transdiagnostic treatment implications, the present study aimed to isolate the unique relationship of RNT with social functioning and life satisfaction in a mixed clinical and non-clinical sample., Methods: In 201 mid-to-later life adult participants (27 with primary diagnoses of bipolar disorder, 84 with major depressive disorder, and 90 healthy volunteers), we measured RNT, social functioning, life satisfaction, trait rumination, DSM-5 diagnoses, depressive symptoms, manic symptoms, cognitive control performance, and global cognitive functioning., Results: Linear regression models revealed that RNT, but not rumination, was significantly associated with poorer social functioning (β = 0.42 p < .001) and reduced life satisfaction (β = -0.42, p < .001) after controlling for clinical and cognitive covariates., Limitations: Limited demographic diversity, cross-sectional design, self-reporting of outcomes., Conclusions: Results suggest that RNT may confer risk for key psychosocial outcomes during middle to later adulthood, over and above the effects of clinical and cognitive variables and independent of diagnostic status. Findings lend support to the notion of RNT as a transdiagnostic process and suggest that RNT may be an important therapeutic target for adults with poor social functioning and/or reduced life satisfaction., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: KEB receives honorarium from the Breakthrough Discoveries for thriving with Bipolar Disorder for her role as Scientific Director of the Integrated Network and as an advisory board member for Merck & Co.

Objective: High levels of optimism (and low levels of pessimism) are associated with improved physical health in adults. However, relatively less is known about these relations in youth. The present study aimed to review the literature investigating optimism, pessimism, and physical health in children and adolescents from populations with and without health conditions., Methods: We conducted a scoping review up until February 2024. Studies were included if they sampled youth (average age ≤18 years) and treated optimism or pessimism as predictors of health behaviors or outcomes. Data on study and sample characteristics, health outcome, optimism construct, and findings were extracted from eligible papers and results were synthesized., Results: Sixty studies were retained. Most studies were conducted in North America, with adolescents, and used cross-sectional designs and self-reported measures of health. Measures of optimism and pessimism differed across studies. Roughly one-third of studies sampled medical populations. Health categories included substance use, diet and physical activity, sexual health practices, medical adherence, other health behaviors, cardiometabolic health, subjective health/health-related quality of life, pain, sleep, and oral health. Generally, we observed adaptive associations between optimism and health. Higher optimism and lower pessimism were most consistently associated with lower rates of substance use and lower cardiometabolic risk., Conclusions: The presence of optimism or the absence of pessimism appears to be associated with various adaptive health outcomes among youth with and without health conditions. Developmental, methodological, and clinical considerations for future research are discussed, such as conducting longitudinal studies with objective measures of health and psychometrically validated instruments., (© The Author(s) 2024.

Cognitive biases reveal underlying affective state by indicating optimism and pessimism. This methodology may permit assessment of positive welfare in animals that have few validated positive welfare indicators, such as bears. Our goal was to validate a judgment bias test for assessing optimism in brown bears, using a touchscreen. After training the bears on a conditional discrimination, we compared responses to an ambiguous stimulus in a 2 × 2 nested design involving four experimental conditions representing presence or absence of a behind-the-scenes tour and presence or absence of a keeper training session with food reinforcement. We recorded bears' behavior during the conditions as a measure of convergent validity. Testing revealed the possibility of pessimism in the absence of reinforcement in one bear. More frustration behaviors were also observed during the no food reinforcement conditions. This is the first experimental demonstration of brown bears using a touchscreen and one of only three reports in which bears have been reported to perform a conditional discrimination. This method of assessing underlying affective state shows promise for the future.

Prior research suggests that repetitive negative thinking (RNT) negatively impacts mental health by intensifying and prolonging emotional reactivity to stress. This study investigated whether an intervention designed to reduce RNT alters emotional reactivity. Young adults with high trait RNT (N = 79) were randomly allocated to an RNT-focused intervention (smartphone app-based, 10 days) or a waiting list before exposure to a standardized stressor. The pre-registered analysis did not reveal a significant condition * time interaction for negative affect. However, exploratory analyses showed that whilst initial increases in negative affect in response to the stressor did not differ between conditions, participants in the intervention condition reported less negative affect throughout the following recovery phase. Additionally, participants in the intervention condition appraised their ability to cope with the stressor as higher and reported less RNT in the recovery phase. In contrast, the intervention did not affect biological stress responses. The findings indicate that RNT-focused interventions might have positive effects on mental health by breaking the self-reinforcing cycle of RNT, negative affect and maladaptive appraisals in response to stress. However, as findings are partly based on exploratory analyses, further research is needed to confirm whether reduced subjective stress reactivity mediates the effects of RNT-focused interventions on psychopathological symptoms., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

In six studies, we find evidence of efficiency neglect: when thinking about the effects of population growth, people intuitively focus on increased demand while neglecting the changes in production efficiency that occur alongside, and often in response to, increased demand. In other words, people tend to think of others solely as consumers, rather than as consumers as well as producers. Efficiency neglect leads to beliefs that the real costs of some consumer goods are rising when they are actually decreasing and may contribute to antiimmigration sentiments because of the fear that increasing local population creates competition for fixed resources. We demonstrate that economic pessimism and antiimmigration sentiments are reduced when people are prompted to consider their own beliefs about increased productivity over time, but are unchanged when they consider their beliefs about increases in demand. Together, these findings shed light on people's lay economic theories and suggest promising interventions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: the aim of this study is to investigate the relationship between death distress, psychological adjustment, optimism, pessimism and perceived stress among nurses working during the COVID-19 pandemic., Method: this study was designed as cross-sectional/cohort. The population of the study involved 408 nurses from Northern Cyprus, which are registered as full members of the Nurse Council. The sample comprised 214 nurses, who volunteered to participate in the study. The study data was collected using a web-based online survey (Demographic form, the Coronavirus Stress Measure, The Optimism and Pessimism Questionnaire, The Brief Adjustment Scale-6, The Death Distress Scale)., Results: the results indicated that perceived stress significantly and negatively predicted optimism (β = -0.21, p < 0.001) and pessimism (β = 0.38, p < 0.001). Perceived stress had significant and positive predictive effects on psychological adjustment (β = 0.31, p < 0.001) and death distress (β = 0.17, p < 0.01). Further analysis results revealed that pessimism mediates the association of stress with psychological adjustment and death distress; however, optimism only mediates the effect of stress on psychological adjustment among nurses., Conclusion: a low level of pessimism is effective in strengthening nurses' psychological adjustment skills againt perceived stress and death distress. Nurses should consider behavioral strategies to help reduce the level of pessimism during periods such as pandemics., Background: (1) High levels of perceived stress increased higher score of psychological adjustment. (2) Pessimism mediates the association of stress with adjustment and death distress. (3) Optimism only mediates the effect of stress on psychological adjustment among nurses.

The cumulative negative effects of prolonged Hypothalamic-Pituitary-Adrenal axis (HPA axis) activation are associated with several age-related diseases. Some psychological traits such as optimism and pessimism have been shown to be related to both health and the stress response, although their relationship with the HPA axis is inconclusive. More stable HPA axis biomarkers, such as hair samples of cortisol (HC) and dehydroepiandrosterone (HDHEA), would help to clarify the association between these psychological traits and HPA axis functioning. The main aim of this study was to test the relationships between optimism and pessimism and chronic stress biomarkers measured in hair (HC and HDHEA). Additionally, a secondary objective was to explore sex differences in HC and HDHEA levels and their relationship with these psychological traits. We measured optimism, pessimism, and their combination (dispositional optimism) using the Life Orientation Test Revised (LOT-R) and chronic stress biomarkers (HC and HDHEA) in 119 healthy participants (46 men and 73 women) between 56 and 81 years old who belonged to a university program. Regression analyses controlling for perceived stress and BMI indicated that higher dispositional optimism was related to lower HC and HC:HDHEA ratio (β = -0.256, p = .008 and β = -0.300, p = .002, respectively). More specifically, higher pessimism was related to higher HC (β = 0.235; p = .012) and HC:HDHEA ratio (β = 0.240; p = .011), whereas higher optimism was associated with a lower HC:HDHEA ratio (β = -0.205; p = .031). Moderation analyses showed no sex differences. To date, this is the first study to investigate the link between these traits and HC and HDHEA in older people. Our results confirm that positive and negative expectations about the future (i.e. optimism and pessimism) may play an important role in health due to their relationship with the HPA axis. They also strengthen the idea that the negative effects of pessimism have a greater weight than the protective effects of optimism in their relationship with HPA axis regulation., Competing Interests: Declaration of competing interest The authors report no conflicts of interest., (Copyright © 2023 The Authors.

Objectives: Hoarding in older adults can have a detrimental effect on daily life. Repetitive negative thinking (RNT) could result in a greater avoidance of discarding and increased saving behaviors; yet, the unique role of RNT on hoarding in older adults remains understudied. This study aimed to investigate whether the intensity of RNT contributes to hoarding in older adults. Methods: Two hundred and sixty-four older adults in Japan (ages 65-86 years, 132 males and 132 females) participated in an online survey. Hierarchical regression analyses were conducted to examine whether RNT could significantly explain the variance of hoarding after controlling for age, sex, years of education, self-reported cognitive impairment, and depression. Results: As we expected, RNT was significantly associated with greater hoarding behaviors, such as excessive acquisition (β = .27, p = .005) and difficulty in discarding (β = .27, p = .003). On the other hand, reflection, repetitive thinking without negative emotional valence, was significantly associated with higher scores on clutter (β = .36 p < .001). Conclusion: Our findings highlight the importance of addressing RNT in the prevention and treatment of hoarding symptoms among older adults, potentially leading to more effective interventions and improved outcomes in managing hoarding behaviors in this population.

Self-compassion is a construct of positive psychology related to personality and cognitive factors. Perfectionism and interpersonal sensitivity are prevalent personality traits among university students and are associated with low self-compassion. Further research is required to comprehend how these mechanisms work in creating self-compassion. Consequently, the current study investigated the direct and indirect relationship between perfectionism and interpersonal sensitivity with self-compassion via repetitive negative thinking. To this end, a sample of 450 students studying in Tehran during the 2022 academic year was selected as the study sample. The results indicated that perfectionism and interpersonal sensitivity demonstrate a negative direct relationship with self-compassion, while perfectionism and interpersonal sensitivity exhibit an indirect relationship with self-compassion via repetitive negative thinking. Based on the findings, it can be concluded that the relationship between perfectionism and interpersonal sensitivity with self-compassion is not straightforward and that repetitive negative thinking can mediate this relationship. The results can be used to improve methods for increasing self-compassion and paying attention to personality, and cognitive factors can be an important step toward more effective self-compassion interventions., (© 2023.

Purpose: Repetitive negative thinking (RNT) is the process of engaging in negatively valenced and habitual thought patterns. RNT is strongly associated with mental health conditions and often affects quality of life. This study explored RNT in older school-age children and adolescents who stutter to quantify the relationship between RNT and self-reported anxiety characteristics. An additional aim was to describe how individual differences in an adolescent's goal when speaking influences the frequency they engage in RNT., Method: Ninety-nine children and adolescents who stutter aged 9-18 years completed a measurement of the frequency/severity of RNT, a screener of anxiety characteristics, and a measure of adverse impact related to stuttering. Children aged 10 years and above also answered questions about their goal when speaking., Results: Individual differences in RNT significantly predicted Overall Assessment of the Speaker's Experience of Stuttering (OASES) Total Scores more so than a child or adolescent's age. Higher generalized or social anxiety scores were significantly correlated with more frequent RNT and higher OASES Total Scores. Individual differences in goal when speaking (i.e., whether or not to stutter openly) were found to predict RNT. Finally, 22 children and adolescents (22.2%) also screened positive for generalized anxiety disorder and 32 (32.3%) screened positive for social anxiety disorder., Discussion: These data provide strong evidence that (a) many children and adolescents who stutter engage in RNT; (b) children and adolescents who engage more frequently in RNT or who have higher OASES Total Scores may be at increased risk for more characteristics of generalized or social anxiety; and (c) individual differences in goal when speaking can predict the degree to which an adolescent engages in RNT., Supplemental Material: https://doi.org/10.23641/asha.23713296.

Background: Repetitive negative thinking (RNT), a cognitive process that encompasses past (rumination) and future (worry) directed thoughts focusing on negative experiences and the self, is a transdiagnostic construct that is especially relevant for major depressive disorder (MDD). Severe RNT often occurs in individuals with severe levels of MDD, which makes it challenging to disambiguate the neural circuitry underlying RNT from depression severity., Methods: We used a propensity score, i.e., a conditional probability of having high RNT given observed covariates to match high and low RNT individuals who are similar in the severity of depression, anxiety, and demographic characteristics. Of 148 MDD individuals, we matched high and low RNT groups ( n = 50/group) and used a data-driven whole-brain voxel-to-voxel connectivity pattern analysis to investigate the resting-state functional connectivity differences between the groups., Results: There was an association between RNT and connectivity in the bilateral superior temporal sulcus (STS), an important region for speech processing including inner speech. High relative to low RNT individuals showed greater connectivity between right STS and bilateral anterior insular cortex (AI), and between bilateral STS and left dorsolateral prefrontal cortex (DLPFC). Greater connectivity in those regions was specifically related to RNT but not to depression severity., Conclusions: RNT intensity is directly related to connectivity between STS and AI/DLPFC. This might be a mechanism underlying the role of RNT in perceptive, cognitive, speech, and emotional processing. Future investigations will need to determine whether modifying these connectivities could be a treatment target to reduce RNT.

Background and Objectives: Although dispositional optimism and pessimism have been prospectively associated with health outcomes, little is known about how these associations manifest in everyday life. This study examined how short-term optimistic and pessimistic expectations were associated with psychological and physiological stress processes., Methods: A diverse sample of adults ( N  = 300) completed a 2-day/1-night ecological momentary assessment and ambulatory blood pressure (ABP) protocol at ∼45-minute intervals., Results: Moments that were more optimistic than typical for a person were followed by moments with lower likelihood of reporting a stressor, higher positive affect (PA), lower negative affect (NA), and less subjective stress (SS). Moments that were more pessimistic than typical were not associated with any affective stress outcome at the following moment. Neither optimism nor pessimism were associated with ABP, and did not moderate associations between reporting a stressor and outcomes., Discussion: These findings suggest that intraindividual fluctuations in optimistic and pessimistic expectations are associated with stressor appraisals.

Background and Objectives: Looming cognitive style (LCS) and intolerance of uncertainty (IUC) are both cognitive risk factors that play an important role in development of anxiety disorders. Even though both are known to be triggered by ambiguous situations, there is inadequate research on how they predict anxiety and repetitive negative thinking (RNT) patterns in response to ambiguity. The current study aimed to examine the interactive association of IUC and LCS with state anxiety and intensity of RNT following exposure to a stressor that involves ambiguity., Methods: Data were collected from 292 (153 women) individuals aged between 18 and 63 (M = 20.82, SD = 5.20) who were administered self-report measures of LCS, IUC, and anxiety followed by a vignette describing an ambiguous situation. State RNT and anxiety were assessed following exposure to the vignette., Results: The results indicated that IUC moderated the association of physical looming with state RNT. Individuals who have elevated levels of both physical looming and IUC reported experiencing more higher frequency of RNT when compared with other individuals., Limitations: Although the manipulation check has shown that the scenario is effective it was not pilot tested. Also, since the manipulation was conducted online, the manipulation may not have been presented in a standardized way to all the participants., Conclusions: Overall, the study shows that the two risk factors enhance each other's effect and lead to more intense levels of repetitive, uncontrollable, and distressing thoughts following exposure to ambiguity., Competing Interests: Declaration of competing interest Authors declare that they have no conflicts of interest in the publication of this work., (Copyright © 2023 Elsevier Ltd.

Background: Repetitive negative thinking (RNT) is a symptom that can negatively impact the treatment and course of common psychiatric disorders such as depression and anxiety. We aimed to characterize behavioral and genetic correlates of RNT to infer potential contributors to its genesis and maintenance., Methods: We applied a machine learning (ML) ensemble method to define the contribution of fear, interoceptive, reward, and cognitive variables to RNT, along with polygenic risk scores (PRS) for neuroticism, obsessive compulsive disorder (OCD), worry, insomnia, and headaches. We used the PRS and 20 principal components of the behavioral and cognitive variables to predict intensity of RNT. We employed the Tulsa-1000 study, a large database of deeply phenotyped individuals recruited between 2015 and 2018., Results: PRS for neuroticism was the main predictor of RNT intensity (R 2 =0.027,p<0.001). Behavioral variables indicative of faulty fear learning and processing, as well as aberrant interoceptive aversiveness, were significant contributors to RNT severity. Unexpectedly, we observed no contribution of reward behavior and diverse cognitive function variables., Limitations: This study is an exploratory approach that must be validated with a second, independent cohort. Furthermore, this is an association study, limiting causal inference., Conclusions: RNT is highly determined by genetic risk for neuroticism, a behavioral construct that confers risk to a variety of internalizing disorders, and by emotional processing and learning features, including interoceptive aversiveness. These results suggest that targeting emotional and interoceptive processing areas, which involve central autonomic network structures, could be useful in the modulation of RNT intensity., Competing Interests: Declaration of competing interest The authors have no competing interests to report., (Copyright © 2023 Elsevier Ltd.

Background: The Psychological Mediation Framework theorizes that repetitive negative thinking (RNT) mediates the relationship between minority stress and mental health, and this theory has been consistently supported by previous research. Yet, it is unclear whether the process or content of RNT is more important in the development of internalizing symptoms in sexual minorities. Consequently, the goal of the current study was to use structural equation modeling to determine whether there are significant indirect effects of repetitive negative thought content in the relationship between minority stress and internalizing psychopathology., Methods: Measures of RNT, internalizing symptoms, and proximal minority stress were completed online by 205 cisgender sexual minority adults. Structural equation modeling was used to examine indirect effects of proximal stress on internalizing symptoms through content-independent RNT, depressive rumination, and sexual orientation-related rumination., Results: Significant direct effects of proximal minority stress on internalizing symptoms were observed. Indirect effects of proximal stress on internalizing symptoms were observed for content-independent RNT and depressive rumination, but not sexual orientation-related rumination., Conclusions: The current study provides evidence that the process and affective valence of RNT contributes more to internalizing symptoms in sexual minorities when compared with sexual orientation-related content. Theoretical and clinical implications are discussed., (© 2023 The Authors. Journal of Clinical Psychology published by Wiley Periodicals LLC.)

Introduction: Underlying factors associated with alcohol hangover psychological symptoms, such as anxiety and depression, have not been identified. Emotion dysregulation and repetitive negative thinking (RNT) are transdiagnostic factors associated with psychopathology, including non-hangover anxiety and depression. The current study prospectively examined the role of emotion dysregulation on subsequent alcohol hangover anxiety and depression symptoms, as well as the moderating role of RNT on this relation among university students., Methods: One hundred thirty-six participants completed baseline assessments of emotion dysregulation (DERS-16) and non-hangover anxiety and depression (DASS-21). Thirty-nine participants reported experiencing alcohol hangover at 2-week follow up and completed assessments of RNT (PTQ) and hangover anxiety and depression (modified DASS-21). Two independent regression-based moderation analyses were conducted to examine the relation of baseline emotion dysregulation, 2-week follow-up RNT, and hangover anxiety and depression symptoms after accounting for baseline non-hangover anxiety and depression symptoms., Results: Among those experiencing alcohol hangover (n = 39), emotion dysregulation and RNT were not associated with hangover related anxiety beyond non-hangover anxiety. Emotion dysregulation significantly predicted hangover depression but was rendered non-significant by the addition of RNT, which was significantly associated with hangover depression. RNT moderated the emotion dysregulation-hangover depression relation such that emotion dysregulation was not associated with future hangover depression at low levels of RNT but was positively associated with hangover depression at moderate to high levels of RNT., Conclusion: Results provide preliminary support for the role of emotion dysregulation and RNT in hangover depression severity., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Objective: Hearing loss (HL) has been linked to commonly studied detrimental mood states, such as loneliness and depression. However, its relationship with other negative emotions remained largely unstudied. We explore the association between HL and anxiety, anger, hostility, poor self-esteem, and pessimism in a national cohort of US Hispanic adults., Study Design: Cross-sectional study., Setting: Multicentered US national epidemiologic study (Hispanic Community Health Study)., Methods: Subjects were ages 18 to 75 with completed audiometric and emotional survey data. Multivariable regressions controlling for age, gender, and education were conducted to analyze the association between HL, measured by 4-frequency pure-tone average (PTA), and emotional states. States included anxiety (Spielberger Trait Anxiety Scale-10), anger (Spielberger Trait Anger Scale), hostility (Cook Medley Cynicism Scale-13), poor self-esteem (Self-Esteem Scale-10), and pessimism (Revised Life Orientation Test)., Results: A total of 4120 to 4341 participants met inclusion criteria, depending on the specific survey; the average age was 46.7 years (standard deviation [SD] = 13.7), and the average PTA was 13.8 dB (SD = 10.1). Controlling for age, gender, and education, HL was associated with all outcomes. Specifically, for every 10 dB worsening in HL, the anxiety score worsened by 0.41 (0.23-0.60), the anger score worsened by 0.40 (0.22-0.58), the hostility score worsened by 0.16 (0.04-0.27), the self-esteem score worsened by 0.25 (0.12-0.38), and the pessimism score worsened by 0.17 (0.04-0.30) (all p < .01)., Conclusion: HL is related to numerous negative mood states beyond loneliness and depression. This includes worse anxiety, anger, hostility, self-esteem, and pessimism. Future studies should investigate whether treating HL improves negative emotional states., (© 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

Background: The first onset of common mental health disorders, such as mood and anxiety disorders, mostly lies in adolescence or young adulthood. Hence, effective and scalable prevention programs for this age group are urgently needed. Interventions focusing on repetitive negative thinking (RNT) appear especially promising as RNT is an important transdiagnostic process involved in the development of depression and anxiety disorders. First clinical trials indeed show positive effects of preventative interventions targeting RNT on adult as well as adolescent mental health. Self-help interventions that can be delivered via a mobile phone app may have the advantage of being highly scalable, thus facilitating prevention on a large scale. This trial aims to investigate whether an app-based RNT-focused intervention can reduce depressive and anxiety symptoms in young people at risk for mental health disorders., Methods: The trial will be conducted in a sample (planned N = 351) of individuals aged 16-22 years with elevated levels of RNT but no current depression or anxiety disorder. In a randomized controlled between-subjects design, two versions of the app-based self-help intervention will be compared to a waiting list control condition. The full RNT-focused intervention encompasses a variety of RNT-reducing strategies, whereas the concreteness training intervention focuses on only one of these strategies, i.e., concrete thinking. The primary outcome (depressive symptoms) and secondary outcomes (anxiety symptoms and RNT) will be measured at pre-intervention, post-intervention (6 weeks after pre-intervention), and follow-up (18 weeks after pre-intervention)., Discussion: This trial aims to find out whether targeting RNT via an app is an effective and feasible way of preventing depression and anxiety disorders in adolescents. Since app-based interventions are highly scalable, this trial might contribute to tackling challenges related to the increasing rates of mental health disorders among young people., Trial Registration: https://www.drks.de , DRKS00027384.

Cognitive risk factors are key in the vulnerability for internalizing disorders. Cognitive risk factors modulate the way individuals process information from the environment which in turn impacts the day-to-day affective experience. In 296 young adults, we assessed two transdiagnostic, general risk factors-repetitive negative thinking (RNT) and anxiety sensitivity in a high-RNT subsample ( N = 119). We also assessed disorderand content-specific risk factors including worry, rumination, and three facets of anxiety sensitivity (cognitive, social, physical). To determine the day-to-day affective experience, we used cell-phone-based ecological momentary assessment to assess the mean and variability of positive and negative affect (PA; NA) over 3-4 months. Two multilevel multivariate Bayesian models were used to predict PA and NA mean and variability from (1) general and (2) specific cognitive risk factors. Mean NA was a nonspecific correlate of cognitive risk across both models, while mean PA was most strongly related to RNT and rumination. NA variability was most strongly related to RNT, rumination, and the physiological facet of anxiety sensitivity. PA variability was a specific correlate of RNT. Results highlight that cognitive risk factors for internalizing disorders manifest in unique patterns of day-to-day emotional experience.

Background: Despite the well-established role of repetitive negative thinking (RNT) in the prediction and maintenance of depression and anxiety, only minimal research to date has investigated RNT in the context of postnatal psychological adjustment., Objective: We examined the relationships between RNT, associated maladaptive cognitive processes, infant responsiveness and psychopathology in a sample of first-time mothers ( N = 235) with babies under 12 months., Methods: Participants completed an online battery of measures that indexed RNT, dampening of positive affect, metacognitive beliefs about RNT, infant responsiveness, depression and anxiety symptoms., Results: As predicted, RNT was correlated with depression. Controlling for depression, RNT was associated with anxiety, dampening positive affect and positive beliefs about RNT. RNT was inversely related to maternal responsiveness, but this relationship was accounted for by depression., Conclusions: Consistent with findings in the broader literature, RNT was associated with depression, anxiety and other unhelpful cognitive processes in the postnatal period, as well as with poor infant responsiveness. Whilst cross-sectional and preliminary, these data suggest there may be potential clinical utility in targeting RNT in first-time mothers.

Background: Depression and anxiety are prevalent in youth populations and typically emerge during adolescence. Repetitive negative thinking (RNT) is a putative transdiagnostic mechanism with consistent associations with depression and anxiety. Targeting transdiagnostic processes like RNT for youth depression and anxiety may offer more targeted, personalised and effective treatment., Methods: A meta-analysis was conducted to examine the effect of psychological treatments on RNT, depression and anxiety symptoms in young people with depression or anxiety, and a meta-regression to examine relationships between outcomes., Results: Twenty-eight randomised controlled trials examining 17 different psychological interventions were included. Effect sizes were small to moderate across all outcomes (Hedge's g depression = -0.47, CI -0.77 to -0.17; anxiety = -0.42, CI -0.65 to -0.20; RNT = -0.45, CI -0.67 to -0.23). RNT-focused and non-RNT focused approaches had comparable effects; however, those focusing on modifying the process of RNT had significantly larger effects on RNT than those focusing on modifying negative thought content. Meta-regression revealed a significant relationship between RNT and depression outcomes only across all intervention types and with both depression and anxiety for RNT focused interventions only., Conclusion: Consistent with findings in adults, this review provides evidence that reducing RNT with psychological treatment is associated with improvements in depression and anxiety in youth. Targeting RNT specifically may not lead to better outcomes compared to general approaches; however, focusing on modifying the process of RNT may be more effective than targeting content. Further research is needed to determine causal pathways.

Introduction: Repetitive negative thinking (RNT) is a transdiagnostic feature that predicts increased mental health risks, inflammation, and reduced engagement in health promoting behaviors. Depression, anxiety, stress, inflammation, higher body mass index (BMI), and low engagement in health behaviors are associated with adverse outcomes during pregnancy as well as postpartum. However, there is limited literature on the associations between RNT and these contributing factors in the perinatal period, an at-risk time during which women may benefit from clinical interventions directed at RNT., Methods: This study examined the contribution of RNT to inflammation [interleukin (IL)-6] and breastfeeding duration through mediating indicators of mental health and BMI. Behavioral and biological assessments occurred during late pregnancy as well as at 4-6 weeks, 4 months, 8 months, and 12 months postpartum., Results: RNT was positively associated with depressive symptoms, anxiety, and perceived stress (ps ≤ .001) at each assessment timepoint, with the strongest associations observed at the pregnancy assessment and significant, but attenuated, associations during postpartum (ps < .01). In modeling of the association between RNT and IL-6, the indirect effect of BMI was significant at each timepoint (95%CIs 0.0013, 0.0052). Women with lower RNT exhibited longer breastfeeding duration (p = .02). These effects were not significantly mediated by mental health indicators., Conclusions: Clinically meaningful relationships, in which RNT predicts mental health, inflammation, and health behavior engagement during pregnancy and postpartum were observed. Clinical interventions to reduce RNT may have unique benefits this time., Limitations: Further research is warranted to determine if therapies to reduce RNT confer unique benefits for maternal and child health., Competing Interests: Declaration of competing interest None., (Copyright © 2022 Elsevier B.V.

Optimistic and pessimistic cognitive biases have been described in many animals and are related to the perceived valence of the environment. We, therefore, hypothesize that such cognitive bias can be adaptive depending on environmental conditions. In reward-rich environments, an optimistic bias would be favoured, whereas in harsh environments, a pessimistic one would thrive. Here, we empirically investigated the potential adaptive value of such bias using zebrafish as a model. We first phenotyped female zebrafish in an optimistic/pessimistic axis using a previously validated judgement bias assay. Optimistic and pessimistic females were then exposed to an unpredictable chronic stress protocol for 17 days, after which fish were euthanized and the sectional area of the different ovarian structures was quantified in both undisturbed and stressed groups. Our results show that zebrafish ovarian development responded to chronic stress, and that judgement bias impacted the relative area of the vitellogenic developmental stage, with pessimists showing higher vitellogenic areas as compared with optimists. These results suggest that pessimism maximizes reproductive investment, through increased vitellogenesis, indicating a relationship between cognitive bias and life-history organismal decisions.

Background and Objectives: Test anxiety, particularly cognitive test anxiety, is negatively associated with academic performance. Previous research has demonstrated that higher levels of perfectionistic concerns predict higher levels of cognitive test anxiety but has not explored potential mediators of this relationship. This study investigated whether repetitive negative thinking mediated the relationship between perfectionistic concerns and cognitive test anxiety in a non-clinical, academic sample., Methods: Participants were Australian university students ( N  = 129, 32 male, 94 female, 3 non-binary), aged between 18 and 53 ( M  = 23.96; SD  = 6.88), recruited through convenience and snowball sampling. Participants completed an online questionnaire assessing demographics, repetitive negative thinking, perfectionistic concerns, and cognitive test anxiety., Results: Mediation analysis yielded a total model accounting for 43.5% of variance in cognitive TA. Perfectionistic concerns significantly accounted for 10.6% of variance direction ( F (1, 127) = 12.21, p  < .001, R 2  = .106), and 32.5% indirectly through RNT ( F (2,126) = 30.81, p  < .001, R 2 = .329)., Conclusions: Findings demonstrate that RNT significantly mediates the relationship between perfectionistic concerns and cognitive test anxiety in this sample. Importantly, these findings may direct future studies towards investigating the effectiveness of targeting repetitive negative thinking in interventions to mitigate levels of cognitive test anxiety.

Identifying factors related to healthcare professionals' mental health has become an imperative topic for offering mental health services to foster their psychological functioning. This study, for the first time, examined the mediating role of optimism and pessimism in the association between parental coronavirus anxiety and depression among Turkish healthcare professionals during the COVID-19 pandemic. Participants included 429 healthcare professionals whose age ranged between 22 and 61 years (50.3% female; M = 36.65, SD  = 7.0). Results from mediation analysis revealed that parental coronavirus anxiety had a significant predictive effect on optimism, pessimism, and depression. Optimism and pessimism also had significant predictive effects on depression. Most importantly, optimism and pessimism mitigated the adverse impact of parental coronavirus anxiety on healthcare professionals' depression. The findings suggest that optimism is an essential source in reducing depression symptoms in the face of parental coronavirus experiences. Decision-makers and health organizations may integrate strength-based approaches into their guidelines to address parental coronavirus anxiety and depression.

Objectives: Fatigue is a prominent symptom of Generalized Anxiety Disorder (GAD). However, the pathways contributing to elevated fatigue in GAD are poorly understood. Sleep disturbance, also prominent in GAD, only partially explains elevated fatigue in GAD. Repetitive negative thinking (RNT) is a cognitive feature of both GAD and sleep disturbance, and RNT has recently also been associated with elevated fatigue. Therefore, this study assessed whether elevated fatigue in GAD is accounted for by a combination of sleep quality and RNT., Design: Between-group, correlational design in 64 primarily university-educated women with and without a GAD diagnosis., Methods: Women completed self-report questionnaires assessing RNT experienced in the past few days, previous night's sleep quality, and current physical and mental fatigue. Hierarchical linear regressions were conducted to assess whether the relationship between GAD status and fatigue is accounted for by RNT and sleep quality., Results: Women with GAD reported lower sleep quality, and higher RNT and physical and mental fatigue, compared to women without GAD. Sleep quality partly accounted for group differences in both types of fatigue (β's > -0.4), whereas RNT fully accounted for group differences in both types of fatigue (β's > 0.29). The relationship between RNT and both types of fatigue was fully accounted for by sleep quality (β's > -0.39)., Conclusions: These findings indicate that heightened RNT amongst women with GAD may be associated with elevated physical and mental fatigue via its detrimental effects on sleep quality. Interventions that reduce RNT may help to alleviate fatigue symptoms in women with GAD., Practitioner Points: Women with Generalized Anxiety Disorder (GAD) have elevated fatigue and repetitive negative thinking (RNT), and poorer self-reported sleep quality, relative to women without GAD. Whereas sleep quality only partially accounts for elevated fatigue in GAD, RNT fully accounts for elevated fatigue, and the relationship between RNT and fatigue is fully accounted for by sleep quality. These findings provide novel evidence that women with GAD may have elevated fatigue because of the detrimental effects of RNT on sleep. These findings suggest that targeting RNT in treatment for GAD may help to reduce fatigue in GAD, by improving sleep quality., (© 2022 The Authors.

Background: Rumination and worry represent two types of repetitive negative thinking (RNT), and their predictive and maintaining roles are well-established in depression and anxiety, respectively. Furthermore, there is an emerging literature on the link between RNT and psychological wellbeing in the perinatal period., Methods: We conducted a scoping review of studies that have investigated the relationship between RNT and perinatal depression and anxiety. We identified 87 papers eligible for inclusion in the review; they included cross-sectional and longitudinal studies, as well as treatment evaluations (pilot trials and randomised controlled trials)., Results: Cross-sectional studies provided evidence of an association between RNT (i.e., rumination and worry) and depression and anxiety, in both pregnancy and postpartum. Longitudinal findings were mixed. Whilst antenatal worry consistently predicted subsequent depression and anxiety (both later in pregnancy and postpartum), rumination did not consistently predict depression. However, there was some evidence that rumination interacted with other processes to predict later psychopathology. Three randomised controlled trials evaluated whether psychological treatments reduce RNT in the perinatal period, only one of which included a clinical sample., Limitations: No experimental investigations were eligible for inclusion in the review., Conclusions: Further studies are needed to further our understanding of the nature and role of RNT in pregnancy and postpartum, and its consequences for maternal mental health. These include (but are not limited to) experimental investigations, studies with large clinical samples, and RCTs evaluating the effectiveness of psychological interventions targeting RNT to prevent and treat perinatal depression and anxiety., (Copyright © 2022 Elsevier B.V.

Identifying the correlates of competition anxiety is fundamental to athletes' well-being and performance. Self-compassion is gaining attention in sport psychology because of its associations with positive outcomes, while repetitive negative thinking (i.e. worry and rumination) is associated with negative conditions, such as anxiety. Building on previous evidence in the general population of associations between self-compassion, repetitive negative thinking, and trait anxiety, we investigated these relations in athletes of different sports. A total of 263 athletes (Mage = 23.72, SD = 6.97, 141 males) completed scales measuring self-compassion, repetitive negative thinking, and trait competition anxiety. Regression models showed the effects of self-compassion and worry on concern (the cognitive component of anxiety), and of worry on somatic anxiety. Gender, number of competitions a year, and years of practice were also associated with trait competition anxiety. A subsequent mediation model revealed significant direct and indirect effects of self-compassion on anxiety, mediated by worry. Results are discussed theoretically and considering their practical implications for athletes.

Prior research has found the differential strength of optimism and pessimism in predicting physical health. However, whether similar findings would be obtained in predicting subjective well-being and the possible underlying mechanisms are still unclear. This study examined the relative strength of optimism and pessimism in predicting adolescent life satisfaction and depression, and further explored the possible mediating mechanisms from the perspective of emotion regulation. A sample of 2672 adolescents ( M age = 13.54 years, SD = 1.04; 55.60% boys) completed a survey assessing optimism and pessimism, the habitual use of reappraisal and acceptance strategies, life satisfaction, and depression. The results from dominance analysis revealed that the presence of optimism was more powerful than the absence of pessimism in predicting adolescent life satisfaction, while the absence of pessimism was more powerful than the presence of optimism in predicting adolescent depression. Moreover, mediation models showed that reappraisal and acceptance mediated both the link between optimism and life satisfaction and the link between pessimism and depression. These findings suggest possible avenues for intervening in different aspects of adolescent subjective well-being.

This paper sought to provide the first validation of a transdiagnostic measure of repetitive negative thinking - the Perseverative Thinking Questionnaire-Child version (PTQ-C) - in young people diagnosed with anxiety and depressive disorders. Participants (N = 114) were 11- to 17-year-olds with complex and comorbid presentations seeking treatment through Child and Adolescent Mental Health Services. Confirmatory factor analyses best supported a three-factor model for the PTQ-C; however, hypotheses of both perfect and close fit were rejected, and a subsequent bifactor model suggested minimal unique variance for each subscale. Results demonstrated good internal consistency, convergent validity and divergent validity for the total score and three PTQ-S subscales: core characteristics, perceived unproductiveness, and consumed mental capacity of negative repetitive thinking. PTQ-C scores did not account for additional variance in anxiety symptoms once worry was considered, indicating that retention of a content-specific measure may be warranted in clinical samples. Findings emphasize the importance of validating clinically relevant measures which were developed with subclinical populations in samples with diagnosed mental health disorders. PRACTITIONER POINTS: Validates Perseverative Thinking Questionnaire in anxious and depressed youth. Support for convergent and divergent validity, and internal consistency. Results suggest measure is appropriate for complex and comorbid presentations., (© 2021 The Authors.

Objectives: Treatment of repetitive negative thinking (RNT) focuses rather on individual than group cognitive behaviour therapy (CBT) treatment. Additionally, little is known on how clients experienced these interventions. This study investigates clients' experiences on participating in a CBT group intervention targeting RNT (RNT-G)., Design: Of the 80 participants, 11 were randomly selected for an in-depth, semi-structured interview after treatment. Interviews focused on what participants experienced as important on group aspects, offered interventions, homework tasks, and possible changes., Methods: All participants were adults, diagnosed with major depressive disorder and/or generalized anxiety disorder and being currently in mental health care treatment. After transcribing the interviews, analyses were performed according to the guidelines of thematic analysis., Results: Four major themes were identified. First, the group format itself was experienced as an important factor of change. The experiences about the different offered interventions during the group formed a second theme. A third theme related to changes in family or professional life and dealing with RNT as a result of the intervention. Finally, group participation, social interactions, and mental health care treatment were experienced as mutually influencing during the intervention., Conclusions: The results of this study shed some light on which treatment interventions were perceived as beneficial during the RNT-G and should therefore be emphasized in treatment. Further, they indicate that the treatment in a group format was experienced as helpful by the participants. Finally, a positive mutual influence between the group intervention and the ongoing individual treatment was experienced., (© 2021 The British Psychological Society.)

Distress is a characteristic of various mental disorders. The transdiagnostic construct repetitive negative thinking (RNT) has been suggested to contribute to distress. However, there is little evidence that this association can actually be found across diagnostic categories. We analyzed this association for phobias, other anxiety disorders, stress disorders, depressive disorders and substance use disorders in 194 treatment-seeking individuals. RNT was associated with distress across all diagnostic categories with high effect sizes. Except for phobias, these associations were not attributable to general emotion regulation abilities. RNT might contribute to distress in several mental disorders which underlines its potential for transdiagnostic interventions., (Copyright © 2022. Published by Elsevier B.V.)

Research suggests that the way individuals are oriented towards the future is deeply embedded in their psychology, shaping how they perceive and react to opportunities and threats, even at unconscious levels. We argue that exposures to opportunities and threats over the life course can shape future orientation at a deep level, and that word-valence effects to survey questions indicate optimistic and pessimistic "perceptual-response reflexes" that are manifestations of unconscious dispositions. Using data collected over 25 years in the Americans' Changing Lives (ACL) study we analyze variation in word-valence effects by age, birth cohort, gender, and race. The broad adult age-range of the sample and the length of follow-up permits the examination of birth cohorts ranging from the "First Children of the 20th Century" (born before 1917) to "Baby Boomers" (born 1947-1962). We find notable differences in age-graded trends across two overarching birth cohort groups: those who reached high school age before the Supreme Court's landmark Brown vs Board of Education decision in 1954 (i.e., born before 1932) and after (i.e., born in 1932 and later). Age-related trends in optimistic perceptual response diverge notably for women versus men, and for Black versus White Americans. Trends in pessimistic perceptual response differ from trends in optimistic response. For example, in early adulthood Black Americans score higher on both optimistic and pessimistic response patterns than White Americans. Birth-cohort differences in both outcomes vary by gender and race. Those differences are interpreted in terms of changes in political, demographic, and sociocultural contexts., Competing Interests: Declarations of interest None.

The replay of task-relevant trajectories is known to contribute to memory consolidation and improved task performance. A wide variety of experimental data show that the content of replayed sequences is highly specific and can be modulated by reward as well as other prominent task variables. However, the rules governing the choice of sequences to be replayed still remain poorly understood. One recent theoretical suggestion is that the prioritization of replay experiences in decision-making problems is based on their effect on the choice of action. We show that this implies that subjects should replay sub-optimal actions that they dysfunctionally choose rather than optimal ones, when, by being forgetful, they experience large amounts of uncertainty in their internal models of the world. We use this to account for recent experimental data demonstrating exactly pessimal replay, fitting model parameters to the individual subjects' choices., Competing Interests: The authors have declared that no competing interests exist.

Past-oriented rumination and future-oriented worry are two aspects of perseverative negative thinking related to the neuroticism endophenotype and associated with depression and anxiety. Our present aim was to investigate the genomic background of these two aspects of perseverative negative thinking within separate groups of individuals with suboptimal versus optimal folate intake. We conducted a genome-wide association study in the UK Biobank database ( n = 72,621) on the "rumination" and "worry" items of the Eysenck Personality Inventory Neuroticism scale in these separate groups. Optimal folate intake was related to lower worry, but unrelated to rumination. In contrast, genetic associations for worry did not implicate specific biological processes, while past-oriented rumination had a more specific genetic background, emphasizing its endophenotypic nature. Furthermore, biological pathways leading to rumination appeared to differ according to folate intake: purinergic signaling and circadian regulator gene ARNTL emerged in the whole sample, blastocyst development, DNA replication, and C-C chemokines in the suboptimal folate group, and prostaglandin response and K + channel subunit gene KCNH3 in the optimal folate group. Our results point to possible benefits of folate in anxiety disorders, and to the importance of simultaneously taking into account genetic and environmental factors to determine personalized intervention in polygenic and multifactorial disorders.

Aim: Preterm birth(<37 gestational weeks) is associated with numerous adversities, however, data on positive developmental outcomes remain limited. We examined if preterm and term born(≥37 gestational weeks) adults differ in dispositional optimism/pessimism, a personality trait associated with health and wellbeing. We assessed if birth weight z-score, neurosensory impairments and parental education modified the outcome., Methods: We systematically searched PubMed and Web of Science for cohort or case-control studies(born ≥ 1970) with data on gestational age and optimism/pessimism reported using the Life-Orientation-Test-Revised in adulthood(≥18 years). The three identified studies(Helsinki Study of Very Low Birth Weight Adults; Arvo Ylppö Longitudinal Study; Avon Longitudinal Study of Parents and Children) provided data for the two-step random-effects linear regression Individual-Participant-Data meta-analysis., Results: Preterm and term borns did not differ on optimism(p = 0.76). Preterms scored higher on pessimism than term borns(Mean difference = 0.35, 95%Confidence Interval 0.36, 0.60, p = 0.007), although not after full adjustment. Preterm born participants, but not term born participants, with higher birth weight z-score, had higher optimism scores (0.30 raw score units per standard deviation increase, 95% CI 0.10, 0.49, p = 0.003); preterm vs term x birth weight z-score interaction p = 0.004)., Conclusions: Preterm and term born adults display similar optimism. In preterms, higher birth weight may foster developmental trajectories promoting more optimistic life orientations., Competing Interests: The authors have declared that no competing interests exist.

Although central to well-being, functional and dysfunctional thoughts arise and unfold over time in ways that remain poorly understood. To shed light on these mechanisms, we adapted a "think aloud" paradigm to quantify the content and dynamics of individuals' thoughts at rest. Across two studies, external raters hand coded the content of each thought and computed dynamic metrics spanning duration, transition probabilities between affective states, and conceptual similarity over time. Study 1 highlighted the paradigm's high ecological validity and revealed a narrowing of conceptual scope following more negative content. Study 2 replicated Study 1's findings and examined individual difference predictors of trait brooding, a maladaptive form of rumination. Across individuals, increased trait brooding was linked to thoughts rated as more negative, past-oriented and self-focused. Longer negative and shorter positive thoughts were also apparent as brooding increased, as well as a tendency to shift away from positive conceptual states, and a stronger narrowing of conceptual scope following negative thoughts. Importantly, content and dynamics explained independent variance, accounting for a third of the variance in brooding. These results uncover a real-time cognitive signature of rumination and highlight the predictive and ecological validity of the think aloud paradigm applied to resting state cognition., (© 2021.

This study examines multi-stakeholders' perceptions of vandalism at tourist attractions in two Asian cities: Bangkok and Singapore. It provides an opportunity to explore the differences and similarities in stakeholder attitudes towards attraction management and reveals desired levels of participation of community in managing vandalism in tourism. This mixed method research employs community survey and interviews of site managers and government officials as its main data collection approach. It also offers an innovative approach to data analysis using the severity and optimist/pessimist psychographic variables coupled with quantitative analytical techniques. The results reveal complex relationship between psychographic profiles, future and current time dimensions, and location. In conclusion, the study offers several recommendations to city managers and policymakers on methods of vandalism control. It also highlights the importance of cultural context and its influence on community involvement. While this study is limited to tourism attractions, it provides a solid foundation for future research, one that can extend into urban planning and public policy design., Competing Interests: The authors have declared that no competing interests exist.

While extensive evidence links service use for mental health problems to demographic variables and positive attitudes, studies have not explored the role of transdiagnostic risk factors, like distress intolerance (DI) and repetitive negative thinking (RNT). This study examined the relationship between parental DI and RNT on mental health treatment seeking for parents themselves and their children. Results suggest higher DI and RNT predict service use among parents (p < 0.05) but were not significantly associated with help seeking for their children, indicating that factors more proximal to the child may have greater influence when parents make treatment decisions for their children. Results also indicte that DI moderates the relationship between parent psychopathology and parent service use, such that parent psychopathology is significantly associated with service use for those with lower DI, but not at moderate or high levels of DI. Implications for marketing mental health information to parents and engaging them in treatment are discussed.

Objective: Uveal melanoma, a rare eye cancer, presents potential vision loss and life threat. This prospective, longitudinal study interrogated the predictive utility of visual impairment, as moderated by optimism/pessimism, on depressive symptoms in 299 adults undergoing diagnostic evaluation., Method: Depressive symptoms (Center for Epidemiologic Studies Depression Scale), subjective (Measure of Outcome in Ocular Disease vision subscale) and objective (logarithm of the minimum angle of resolution) visual impairment, and optimism/pessimism (Life Orientation Test-Revised) were assessed before diagnostic evaluation and 1 week, 3 months, and 12 months after diagnosis. Multilevel modeling, with repeated measures (Level 1) nested within individuals (Level 2) and imputation of missing data (Blimp software), was performed., Results: Depressive symptoms were significantly more elevated 1 week after diagnosis in cancer patients (n = 107) versus patients not diagnosed with cancer (n = 192). Higher subjective (but not objective) visual impairment predicted greater depressive symptoms (p < .001). Across the entire sample, the two-way (Optimism/Pessimism × Subjective Visual Impairment) interactions were statistically significant (ps < .05), but not the three-way interaction (with diagnosis). The positive association between subjective visual impairment and depressive symptoms was significant at low and moderate levels of optimism (ps < .001), but not at high optimism (p > .05). The association was significant at high and moderate levels (ps < .001), but not low (p > .05) levels of pessimism., Conclusions: Elevated depressive symptoms are evident in adults who do (vs. do not) receive a diagnosis of uveal melanoma but appear to remit within 3 months. Perceived impaired vision, especially coupled with low optimism or high pessimism, predicts depressive symptoms over time, with implications for intervention.
