Women report more psychological distress than men, which may be related to both biological sex and socio-cultural gender. We tested whether associations between gender and distress differ for women and men. The cross-sectional sample consisted of 678 Dutch people (54% women). Gender roles were assessed as masculinity and femininity. A composite gender norm score was calculated by summing gendered sociodemographics. Multivariate regressions examined sex, gender, and their interaction for depressive symptoms, anxiety, and perceived stress, additionally adjusted. Women reported more psychological distress. People scoring higher on masculine gender roles, but not feminine gender roles, reported lower psychological distress. A higher gender norm score was related to more depressive symptoms and perceived stress. This association was only present in men and was explained by health-related covariates. This research shows that there is a need to further elaborate on the discrepancies between sex and gender in health psychology research to better understand individual differences.

Maternal love and caregiving are pillars for optimal child development and may affect infant outcomes from pregnancy onwards. The present study aimed to examine whether maternal trait mindfulness during pregnancy and pre- and postnatal maternal-infant bonding were associated with maternal perceptions of infant temperament and social-emotional development. In total, 408 Dutch women (M age = 31.33, SD = 3.59) participated in a prospective perinatal cohort study and completed questionnaires on trait mindfulness, prenatal bonding, postnatal bonding, infant temperament, and infant social-emotional development at 20 and 28 weeks of gestation, and 10 weeks, 6 and 12 months postpartum, respectively. Path analyses demonstrated that higher levels of the trait mindfulness facet non-judging (i.e., refraining from judgments about own feelings and thoughts) were associated with more pre- and postnatal maternal bonding and fewer social-emotional problems as perceived by the mother. Adopting an accepting and non-judgmental attitude may promote positive feelings of bonding and benefit the infant in terms of having fewer social-emotional problems in the first year of life. Mindfulness interventions may be offered to pregnant women in order to enhance maternal bonding and improve infant outcomes after birth.

Objectives Mindfulness-Based Stress Reduction (MBSR) has been shown to decrease general feelings of distress. It is not known to what extent such beneficial effects are associated with attenuation of physiological responses to challenging psychological situations. The aim of the present study was to examine potential associations between general decreases in subjective distress and changes in acute cardiac and cortical responses during recall of a recent stressful episode between pre- and post-MBSR. Method Fifty-eight MBSR participants (77.6% female, mean age 43.8 years, SD = 13.1) took part in a laboratory examination before and after MBSR. Measurements of the electrocardiogram (ECG) and electroencephalogram (EEG) were performed during the whole protocol including the stress recall task. Results The MBSR group showed overall decreases in general negative affect and an increase in heart rate variability from pre- to post-intervention. Out of six physiological outcomes (heart rate, heart rate variability, theta, alpha, beta, and gamma power at Fz), only a decreased response of gamma power during the stress task was significant. The subjective and physiological changes were unrelated. Conclusions The present results suggest that the favourable effects of MBSR on general stress reduction may not be clearly reflected in cortical electrical wave activity or vagal cardiac response during recall of a recent stressful episode. The few changes found in cardiac and cortical activity may be due to either effects independent of general subjective feelings or independent of the intervention altogether.

Background We examined the risk of psychosocial distress, including Type D personality, depressive symptoms, anxiety, positive mood, hostility, and health status fatigue and disease specific and generic quality of life for MACE in patients with non-obstructive coronary artery disease (NOCAD). Methods In the Tweesteden mild stenosis (TWIST) study, 546 patients with NOCAD were followed for 10 years to examine the occurrence of cardiac mortality, a major cardiac event, or non-cardiac mortality in the absence of a cardiac event. Cox proportional hazard models were used to examine the impact of psychosocial distress and health status on the occurrence of MACE while adjusting for age, sex, disease severity, and lifestyle covariates. Results In total 19% of the patients (mean age baseline = 61, SD 9 years; 52% women) experienced MACE, with a lower risk for women compared to men. Positive mood (HR 0.97, 95%CI 0.95–1.00), fatigue (HR 1.03, 95%CI 1.00–1.06), and physical limitation (HR 0.99, 95%CI 0.98–1.00) were associated with MACE in adjusted models. No significant interactions between sex and psychosocial factors were present. Depressive symptoms were predictive of MACE, but no longer after adjustment. Conclusions In patients with NOCAD fatigue, low positive mood, and a lower physical limitation score were associated with MACE, without marked sex differences. Type D personality, psychosocial factors, and health status were not predictive of adverse outcomes. Reducing psychosocial distress is a valid intervention goal by itself, though it is less likely to affect MACE in patients with NOCAD.

Background: The coronavirus disease 2019 (COVID-19) pandemic had brought negative consequences and new stressors to mothers. The current study aims to compare factors predicting maternal mental health during the COVID-19 lockdown in China, Italy, and the Netherlands. Methods: The sample consisted of 900 Dutch, 641 Italian, and 922 Chinese mothers (age M=36.74, SD=5.58) who completed an online questionnaire during the lockdown. Ten-fold cross validation models were applied to explore the predictive performance of related factors for maternal mental health, and also to test similarities and differences between the countries. Results: COVID-19 related stress and family conflict are risk factors and resilience is a protective factor in association with maternal mental health in each country. Despite these shared factors, unique best models were identified for each of the three countries. In Italy, maternal age and poor physical health were related to more mental health symptoms, while in the Netherlands maternal high education and unemployment were associated with mental health symptoms. In China, having more than one child, being married, and grandparental support for mothers were important protective factors lowering the risk for mental health symptoms. Moreover, high SES (mother's high education, high family income) and poor physical health were found to relate to high levels of mental health symptoms among Chinese mothers. Conclusions: These findings are important for the identification of at-risk mothers and the development of mental health promotion programs during COVID-19 and future pandemics.

Background During the COVID-19 pandemic, telemedicine was advocated and rapidly scaled up worldwide. However, little is known about for whom this type of care is acceptable. Objective To examine which patient characteristics (demographic, medical, psychosocial) are associated with telehealth care satisfaction, attitude toward telehealth, and preference regarding telehealth over time in a cardiac patient population. Methods In total, 317 patients were recruited at the Elisabeth-TweeSteden Hospital in The Netherlands. All patients who had received telehealth care (telephone and video) in the previous 2 months were approached for participation. Baseline, 3-month, and 6-month questionnaires were administered online. A 3-step latent class analysis was conducted to identify trajectories of telehealth use over time and the possible association of the found trajectories with external variables. Results Five trajectories (classes) were identified for satisfaction with telehealth and 4 for attitude toward telehealth. Patients with higher distress, lower physical and mental health, higher scores on pessimism, and negative affectivity were more likely to be less satisfied. Patients with no partner, more comorbidities, higher distress, lower physical and mental health, and higher scores on pessimism were more likely to hold a negative attitude toward telehealth. For the future application of telehealth, marital status, comorbidities, digital health literacy, and pessimism were significantly related. Conclusion Results show that patients’ profiles should be considered when offering telehealth care and that the “one size fits all” approach does not apply. Results can inform clinical practice on how to better implement remote health care in the future while considering a personalized approach.

Objective To assess the association between trajectories of comorbid anxiety and depressive (CAD) symptoms assessed in each pregnancy trimester and physiological birth. Design Large longitudinal prospective cohort study with recruitment between January 2013 and September 2014. Setting Primary care, in the Netherlands. Population Dutch-speaking pregnant women with gestational age at birth ≥37 weeks, and without multiple pregnancy, severe psychiatric disorder or chronic disease history. Methods Pregnancy-specific anxiety and depressive symptoms were measured prospectively in each trimester of pregnancy using the negative affect subscale of the Tilburg Pregnancy Distress Scale and Edinburgh (Postnatal) Depression Scale. Data on physiological birth were obtained from obstetric records. Multivariate growth mixture modelling was performed in MPLUS to determine longitudinal trajectories of CAD symptoms. Multiple logistic regression analysis was used to examine the association between trajectories and physiological birth. Main outcome measures Trajectories of CAD symptoms and physiological birth. Results Seven trajectories (classes) of CAD symptoms were identified in 1682 women and subsequently merged into three groups: group 1—persistently low levels of symptoms (reference class 1; 79.0%), group 2—intermittently high levels of symptoms (classes 3, 6 and 7; 11.2%), and group 3—persistently high levels of symptoms (classes 2, 4 and 5; 9.8%). Persistently high levels of CAD symptoms (group 3) were associated with a lower likelihood of physiological birth (odds ratio 0.67, 95% confidence interval 0.47–0.95, P = 0.027) compared with the reference group (persistently low levels of symptoms), after adjusting for confounders. Conclusions This study is the first showing evidence that persistently high CAD levels, assessed in each pregnancy trimester, are associated with a lower likelihood

Research indicates that fear was an important factor in determining individual responses to COVID-19, predicting relevant behaviors such as compliance to preventive measures (e.g., hand washing) and stress reactions (e.g., poor sleep quality). Given this central role of fear, it is important to understand more about its temporal changes during the COVID-19 pandemic. This article describes a publicly available dataset that contains longitudinal assessment of fear of COVID-19 and other relevant constructs during the first 15 months of the pandemic. Particularly, the dataset contains data from two different samples. The first sample consists predominantly of Dutch respondents (N = 439) who completed a cross-sectional survey in March 2020. The second sample consists of a large-scale longitudinal survey (N = 2000 at T1), including respondents with a broad range of nationalities (though predominantly residing in Europe and North America; 95.6%). The respondents of the second sample completed the survey between April 2020 and August 2020 using the Prolific data collection platform. In addition, one follow-up assessment was completed in June 2021. The measures included in the survey were fear of COVID-19, demographic information (age, gender, country of residence, education level, and working in healthcare), anxious traits (i.e., intolerance of uncertainty, health anxiety, and worrying), media use, self-rated health, perceived ability to prevent infection, and perceived risk for loved ones. Additionally, at the follow-up assessment in June 2021, respondents were asked whether they were vaccinated against COVID-19 or were planning to get vaccinated. The datafiles of this study have been made available through the Open Science Framework and can be freely reused by psychologists, social scientists, and other researchers who wish to investigate the development, correlates, and consequences of fear of COVID-19.

Background: Psychological distress (PD) and fear of cancer recurrence (FCR) are common consequences of surviving cancer. Online self-help training could help many cancer survivors deal with PD and FCR at low costs.Purpose: To evaluate the long-term effectiveness of the CAncer REcurrence Self-help Training (CAREST trial) to reduce PD and FCR. Moreover, to evaluate the relation between FCR and PD across time and identify subgroups representing different change trajectories in FCR over time and their predictors.Methods: This multicenter randomized controlled trial included 262 female breast cancer survivors, assigned to online self-help training or care as usual. Participants completed questionnaires at baseline and four times during the 24-month follow-up. The primary outcomes were PD and FCR (Fear of Cancer Recurrence Inventory). Latent growth curve modeling (LGCM) and repeated measures latent class analysis (RMLCA) were performed, both according to the intention-to-treat principle.Results: LGCM showed no differences between the average latent slope in both groups for both PD and FCR. The correlation between FCR and PD at baseline was moderate for the intervention group and strong for the CAU group and did not significantly decrease over time in both groups. RMLCA revealed five latent classes and several predictors of class membership.Conclusions: We did not find a long-term effect of the CBT-based online self-help training in reducing PD or FCR, nor in their relation. Therefore, we recommend adding professional support to online interventions for FCR. Information about FCR classes and predictors may contribute to improvement of FCR interventions.

Researchers commonly study associations between latent variables measured with items showing ordinal and skewed score distributions. Researchers can estimate associations between latent variables according to several statistical methods that vary for instance in how they handle the presence of skewness and measurement error in the item scores. In this commentary I use a computer simulation to illustrate that ignoring skewness or measurement error in questionnaire item scores often results in biased effect estimates, especially when testing interaction effects.

Background Fear is an evolutionary adaptive emotion that serves to protect the organism from harm. Once a threat diminishes, fear should also dissipate as otherwise fear may become chronic and pathological. While actual threat of the COVID-19 pandemic (i.e., number of infections, hospitalizations, and deaths) has substantially varied over the course of the pandemic, it remains unclear whether (subjective) fear has followed a similar pattern. Method To examine the development of fear of COVID-19 during the pandemic and investigate potential predictors of chronic fear, we conducted a large online longitudinal study (N = 2000) using the Prolific platform between April 2020 and June 2021. Participants were voluntary response samples and consisted of residents of 34 different countries. The Fear of the Coronavirus Questionnaire (FCQ) and several other demographic and psychological measures were completed monthly. Results Overall, we find that fear steadily decreased since April 2020. Additional analyses showed that elevated fear was predicted by region (i.e., North America > Europe), anxious traits, gender, risks for loved ones, general health, and media use. Limitations The interpretation of the results of this study is limited by the non-representativeness of the sample and the lack of data points between August 2020 and June 2021. Conclusions This study helps to characterize the trajectory of fear levels throughout the COVID-19 pandemic and establish several relevant predictors of increased fear.

This study aims to estimate the global, regional, and national burden of depressive disorders in 204 countries and territories from 1990 to 2019. All data were obtained from the 2019 Global Burden of Disease (GBD) study. Age-period-cohort (APC) modeling was conducted to disentangle age, period, and birth cohort effects on depression incidence. We compared these estimates across regions classified based on their socio-demographic index (SDI). The Estimated Annual Percentage Change (EAPC) was calculated for each of the 204 countries and territories to identify the top five countries with increased depression incidence (Spain, Mexico, Malaysia, the United States of America, and Uruguay) and the top five countries with decreased depression incidence (Singapore, Estonia, Cuba, Maldives, and Sri Lanka). The results from APC analysis indicate that although depression incidence has decreased globally, the incidence rate in high SDI regions is still increasing, especially in the younger generations. Findings suggest that currently some populations are in need of receiving more psychological support (i.e., individuals born after 1950s in high SDI regions; males in middle SDI regions). Forthcoming studies could corroborate our findings using individual-level data which may guide future prevention and intervention of depression in high-risk populations or regions.

Aim Type D personality, a joint tendency toward negative affectivity (NA) and social inhibition (SI), has been linked to various medical and psychosocial outcomes. The recent failure to replicate earlier findings could result from the various methods used to assess the Type D effect. Despite recommendations to analyze the continuous NA and SI scores, a popular approach groups people as having Type D personality or not. This dichotomous method cannot distinguish a Type D effect from situations where only NA or SI is causally related to the outcome, suggesting the literature contains studies that falsely conclude that having high scores on both traits is causally important. Here, we systematically assess the extent of this problem. Methods We conducted a systematic review including all studies that estimated a Type D effect on any outcome according to both the continuous and dichotomous method. Results 158 previously published analyses were included in our review. In 89 of those analyses a Type D effect was concluded based on the dichotomous method. Of those 89 analyses, only 37 (41.6%) were a Type D effect based on the continuous method, while 42 (47.2%) were main effects of NA or SI only. Conclusion Half of the published Type D effects according to the dichotomous method may more likely be effects of NA or SI only. Earlier published studies using the dichotomous method should be reanalyzed using the continuous method to determine whether it is really Type D or merely NA or SI that is driving the outcome.

A comment on the recently published letter by Grogan and Srinivasan: The effect of antenatal depressive and anxious symptoms on the rate of physiological births.

Background: The COVID-19 pandemic drastically impacted on family life and may have caused parental distress, which in turn may result in an overreliance on less effective parenting practices. Objective: The aim of the current study was to identify risk and protective factors associated with impaired parenting during the COVID-19 lockdown. Key factors predicting maternal harsh discipline were examined in China, Italy, and the Netherlands, using a cross-validation approach, with a particular focus on the role of allomaternal support from father and grandparents as a protective factor in predicting maternal harshness. Methods: The sample consisted of 900 Dutch, 641 Italian, and 922 Chinese mothers (age M = 36.74, SD = 5.58) who completed an online questionnaire during the lockdown. Results: Although marital conflict and psychopathology were shared risk factors predicting maternal harsh parenting in each of the three countries, cross-validation identified a unique risk factor model for each country. In the Netherlands and China, but not in Italy, work-related stressors were considered risk factors. In China, support from father and grandparents for mothers with a young child were protective factors. Conclusions: Our results indicate that the constellation of factors predicting maternal harshness during COVID-19 is not identical across countries, possibly due to cultural variations in support from fathers and grandparents. This information will be valuable for the identification of at-risk families during pandemics. Our findings show that shared childrearing can buffer against risks for harsh parenting during COVID-19. Hence, adopting approaches to build a pandemic-proof community of care may help at-risk parents during future pandemics.

We examined internet searches indicative of abusive parental behaviors before and after the World Health Organization’s declaration of COVID-19 as a pandemic (March 11, 2020) and subsequent lockdown measures in many countries worldwide. Using Google Trends, we inferred search trends between December 28, 2018, and December 27, 2020, for queries consisting of “mother,” “father,” or “parents” combined with each of the 11 maltreatment-related verbs used in the Conflict Tactics Scales, Parent-Child version. Raw search counts from the Google Trends data were estimated using Comscore. Of all 33 search terms, 28 terms showed increases in counts after the lockdowns began. These findings indicate a strong increase in internet searches relating to occurrence, causes, or consequences of emotional and physical maltreatment since the lockdowns began and call for the use of maltreatment-related queries to direct parents or children to online information and support.

This study examined whether parental depression and anxiety predict adolescent emotional distress and glycated hemoglobin A1c (HbA1c) 1 year later and whether a relation between parental distress and HbA1c is mediated by the level of parental involvement in diabetes care and by treatment behaviors. Methods: Longitudinal path modeling was applied to data from 154 adolescents and parents from diabetes centers participating in the Longitudinal study of Emotional problems in Adolescents with type 1 diabetes and their Parents/caregivers (Diabetes LEAP). At baseline and 1-year follow-up, participants completed measures of depression and anxiety. HbA1c was extracted from medical charts. Responsibility and treatment behavior questionnaires were completed by adolescents at baseline. Results: Baseline parental depressive and anxiety symptoms were not associated with 1-year adolescent depressive symptoms, anxiety symptoms, and HbA1c. Responsibility division and treatment behaviors did not mediate associations between parental emotional distress and 1-year HbA1c. Conclusions: Parental depressive and anxiety symptoms did not predict adolescent health outcomes 1 year later. Future studies may determine whether the link is present in case of mood/anxiety disorders or severe diabetes-specific distress, or whether adolescents are resilient in the face of parental distress.

Contains fulltext : 284115.pdf (Publisher’s version ) (Open Access), Background The COVID-19 pandemic has drastically impacted many aspects of society and has indirectly produced various psychological consequences. This systematic review aimed to estimate the worldwide prevalence of posttraumatic stress disorder (PTSD) in children due to the COVID-19 pandemic, as well as to identify protective or risk factors contributing to child PTSD. Methods: We conducted a systematic literature search in the PubMed, ProQuest, PsycINFO, Embase, Web of Science, WanFang, CNKI, and VIP databases. We searched for studies published between January 1, 2020 and May 26, 2021, that reported the prevalence of child PTSD due to the COVID-19 pandemic, as well as factors contributing to child PTSD. Eighteen studies were included in our systematic review, of which 10 studies were included in the meta-analysis. Results: The estimated prevalence of child PTSD after the COVID-19 outbreak was 28.15% (95% CI: 19.46-36.84%, I2 = 99.7%). In subgroup analyses for specific regions the estimated prevalence of post-pandemic child PTSD was 19.61% (95% CI: 11.23-27.98%) in China, 50.8% (95% CI: 34.12-67.49%) in the USA, and 50.08% in Italy (95% CI: 47.32-52.84%). Conclusions: Factors contributing to child PTSD were categorized into four aspects: personal factors, family factors, social factors and infectious diseases related factors. Based on this, we presented a new framework summarizing the occurrence and influence of the COVID-19 related child PTSD, which may contribute to a better understanding, prevention and development of interventions for child PTSD in forthcoming pandemics.

BACKGROUND: Patient reported outcome measures (PROMs) such as health status (HS) and quality of life (QOL) are frequently used interchangeably while they represent different outcomes. Whether a discrepancy exists in patients with intermittent claudication (IC) in changes over time between HS and QOL is unclear. This study aimed to investigate the strength and the direction of the association between HS and QOL over time in patients with IC that underwent supervised exercise therapy (SET).MATERIAL AND METHODS: Patients were part of the ELECT multi-center prospective cohort study. One goal of this study was to obtain data on HS and QOL at different time intervals of patients with IC that underwent SET. HS (VascuQOL-6) and QOL (WHOQOL-BREF) were completed at baseline, 3 months, and 6 months follow up. Pearson's correlation coefficients and the associated common variances (R2) were calculated to measure the strength and the direction of the association between HS and QOL in changes between baseline and follow-up moments.RESULTS: In total, 177 patients were included in data analyses. Only changes in physical QOL and overall QOL had a small correlation with changes over time in HS, at both 3- and 6 months follow up (respectively R2=.14; P < 0.001 and R2 = 0.12; P < 0.001 for physical QOL and R2 = 0.18; P < 0.001 and R2 = 0.13; P < 0.001 for overall QOL).CONCLUSIONS: This study showed that HS and QOL provide different outcomes in patients with IC that underwent SET. Future studies should be aware of these differences before PROMs are being incorporated as an outcome measure in clinical studies.

Vaccines are an important tool for governments and health agencies to contain and curb the Coronavirus Disease-19 (COVID-19) pandemic. However, despite their effectiveness and safeness, a substantial portion of the population worldwide is hesitant to get vaccinated. In the current study, we examined whether fear of COVID-19 predicts vaccination willingness. In a longitudinal study (N = 938), fear for COVID-19 was assessed in April 2020 and vaccination willingness was measured in June 2021. Approximately 11% of our sample indicated that they were not willing to get vaccinated. Results of a logistic regression showed that increased fear of COVID-19 predicts vaccination willingness 14 months later, even when controlling for several anxious personality traits, infection control perceptions, risks for loved ones, self-rated health, previous infection, media use, and demographic variables. These results show that fear of COVID-19 is a relevant construct to consider for predicting and possibly influencing vaccination willingness. Nonetheless, sensitivity and specificity of fear of COVID-19 to predict vaccination willingness were quite low and only became slightly better when fear of COVID-19 was measured concurrently. This indicates that other potential factors, such as perceived risks of the vaccines, probably also play a role in explaining vaccination willingness.

Background The course and different characteristics of acute and posttraumatic stress disorder (ASD, PTSD) in trauma populations are unclear. Objective The aims were to identify longitudinal trajectories of PTSD, to establish a risk profile for ASD and PTSD based on patients’ sociodemographic, clinical, and psychological characteristics, and to study the effect of ASD and dissociation on PTSD during 12 months after trauma. Method Patients completed questionnaires after inclusion and at 3, 6, 9, and 12 months afterwards. Trajectories were identified using repeated measures latent class analysis (RMLCA). The risk profile was based on a ranking of importance of each characteristic using Cohen’s d effect sizes and odds ratios. The impact of ASD and dissociation on PTSD was examined using logistic regression analyses. Results Altogether, 267 patients were included. The mean age was 54.0 (SD = 16.1) and 62% were men. The prevalence rate of ASD was approximately 21.7% at baseline, and 36.1% of trauma patients exhibited PTSD at 12 months after injury. Five trajectories were identified: (1) no PTSD symptoms, (2) mild, (3) moderate, (4) subclinical, and (5) severe PTSD symptoms. These trajectories seemed to remain stable over time. Compared with patients in other trajectories, patients with ASD and (subclinical) PTSD were younger and scored higher on anxiety, depressive symptoms, neuroticism, and trait anxiety. Regarding dissociation symptoms, inability to recall memories about the event was significantly more present than an altered sense of reality, (105 (40.7%) versus 56 (21.7%), p = .031), although that symptom had the strongest likelihood for PTSD. Patients with dissociation were significantly at risk for PTSD than patients without dissociation (OR = 4.82; 95%CI: 1.91–12.25). Conclusions Psychological factors characterized ASD and trajectories of PTSD during 12 months post-trauma. Healthcare providers who are aware

Methods: The sample consisted of 900 Dutch, 641 Italian, and 922 Chinese mothers (age M = 36.74, SD = 5.58) who completed an online questionnaire during the lockdown. Results: Although marital conflict and psychopathology were shared risk factors predicting maternal harsh parenting in each of the three countries, cross-validation identified a unique risk factor model for each country. In the Netherlands and China, but not in Italy, work-related stressors were considered risk factors. In China, support from father and grandparents for mothers with a young child were protective factors. Conclusions: Our results indicate that the constellation of factors predicting maternal harshness during COVID-19 is not identical across countries, possibly due to cultural variations in support from fathers and grandparents. This information will be valuable for the identification of at-risk families during pandemics. Our findings show that shared childrearing can buffer against risks for harsh parenting during COVID-19. Hence, adopting approaches to build a pandemic-proof community of care may help at-risk parents during future pandemics.

Contains fulltext : 234453.pdf (Publisher’s version ) (Open Access), We examined internet searches indicative of abusive parental behaviors before and after the WHO declaration of a COVID-19 pandemic (March 11th 2020) and lockdown measures followed in many countries across the world. Using Google Trends, we inferred search trends between December 28th 2018 and December 27th 2020 for queries consisting of "mother", "father" or "parents" combined with each of the 11 maltreatment-related verbs used in the Conflict Tactics Scale Parent-Child version. Raw search counts from the Google Trends data were estimated using Comscore. Of all 33 search terms, 28 terms showed increases in counts after the lockdown. These findings indicate a strong increase in internet searches relating to occurrence, causes or consequences of emotional and physical maltreatment since the lockdown and call for the use of maltreatment-related queries to direct parents or children to online information and support.

Background The course and corresponding characteristics of quality of life (QOL) domains in trauma population are unclear. Our aim was to identify longitudinal QOL trajectories and determine and predict the sociodemographic, clinical, and psychological characteristics of trajectory membership in physical trauma patients using a biopsychosocial approach. Methods Patients completed a questionnaire set after inclusion, and at 3, 6, 9, and 12 months follow-up. Trajectories were identified using repeated-measures latent class analysis. The trajectory characteristics were ranked using Cohen’s d effect size or phi coefficient. Results Altogether, 267 patients were included. The mean age was 54.1 (SD = 16.1), 62% were male, and the median injury severity score was 5.0 [2.0—9.0]. Four latent trajectories were found for psychological health and environment, five for physical health and social relationships, and seven trajectories were found for overall QOL and general health. The trajectories seemed to remain stable over time. For each QOL domain, the identified trajectories differed significantly in terms of anxiety, depressive symptoms, acute stress disorder, post-traumatic stress disorder, Neuroticism, trait anxiety, Extraversion, and Conscientiousness. Discussion Psychological factors characterized the trajectories during 12 months after trauma. Health care providers can use these findings to identify patients at risk for impaired QOL and offer patient-centered care to improve QOL.

Since the outbreak of the coronavirus disease (COVID-19), several reports have shown that fear relating to COVID-19 has sharply increased. To measure fear of COVID-19, various questionnaires have been developed in parallel. However, fear concerning COVID-19 is not necessarily a uniform construct and the different questionnaires may cover diverse aspects. To examine the underlying structure of fear of COVID-19, we conducted structural equation modelling and network analyses on four scales in an online convenience sample (N = 829). Particularly, the Fear of COVID-19 Scale (Ahorsu et al., 2020), the Fear of the Coronavirus Questionnaire (Mertens et al., 2020), and the COVID Stress Scales (Taylor, Landry, Paluszek, Fergus et al., 2020, Taylor, Landry, Paluszek, Rachor et al., 2020) were included in our study, along with a new scale that also assessed socio-economic worries relating to COVID-19. We found that fear of COVID-19 was best classified into four clusters: Fear of health-related consequences, fear of supplies shortages and xenophobia, fear about socio-economic consequences, and symptoms of fear (e.g., compulsions, nightmares). We also find that a central cluster of items centered on fear of health, which likely represents the core of fear of COVID-19. These results help to characterize fear due to COVID-19 and inform future research.

Contains fulltext : 220970.pdf (Publisher’s version ) (Open Access), BACKGROUND: Psychological factors are associated with adverse prognosis in patients with ischemic heart disease (IHD). However, it is unknown whether these risk factors differ between women and men. METHODS: PubMed, EMBASE, and PsycINFO were searched to identify studies assessing the risk of psychological factors for major adverse cardiovascular events (MACE) in samples with IHD. Psychological factors included anger/hostility, anxiety, depression, psychological distress, social support, Type A behavior pattern, Type D personality, and Posttraumatic Stress Disorder (PTSD). RESULTS: A total of 44 articles (64 separate reports) including 227,647 women and 321,894 men reporting confounder-adjusted hazard ratios (HRs) or relative risks (RRs) were included in the primary analysis. Results based on random-effects models showed that the association between psychological factors (all combined) and MACE was stronger in men (n = 321,236; 57 reports; HR = 1.37, 95%CI 1.27-1.48) than in women (n = 226,886; 56 reports; HR = 1.21, 95%CI 1.12-1.30; p = .017). A subset of the studies focusing on women showed significant associations between anger/hostility, depression, and distress with MACE. For men, statistically significant associations were found for anxiety, depression, and distress with MACE. CONCLUSIONS: Psychological factors are associated with MACE in samples with IHD in both women and men, with a small, but significant higher risk for men. Because of the limited number of studies on other psychological factors than depression and anxiety and the current major focus on MACE reflecting lesions in the major coronary arteries which is more typical in men than women, more research is needed to better identify sex and gender differences in IHD.

Background: Health-care systems nowadays rely on complementary patient care by informal caregivers. The need for, and burden on, informal caregivers will likely increase in the upcoming years. This study aimed to examine the burden on caregivers when providing care for elderly patients undergoing major abdominal surgery.Methods: A single-centre longitudinal cohort study was conducted between November 2015 and June 2018 in the Amphia hospital in Breda, the Netherlands. Patients aged 70+ undergoing elective surgery for colorectal carcinoma (CRC) or an abdominal aortic aneurysm (AAA) were included in this study. Informal caregiver burden was assessed and compared over time using the Caregiver Strain Index (CSI) at the outpatient clinic visit, at discharge, 2 weeks post-discharge and after 6 and 12 months. The effects of patient- and caregiver-related factors on the experienced caregiver strain were examined.Results:CSI scores of 248 caregivers were significantly increased at discharge (3.5 vs 2.6; p < 0.001) and 2 weeks post-discharge (3.3 vs 2.6; p < 0.001). After 12 months, scores dropped below baseline scores (1.8 vs 2.6; p = 0.012). The highest strain was observed 2 weeks post-discharge for AAA patients and at discharge for CRC patients. Older age, physical or cognitive impairment and burden of comorbidity were associated with an increased caregiver strain at baseline. Type of surgery was independently associated with the change in mean CSI scores over time; a bigger change in caregiver burden is observed after open surgery.Conclusion: In the early postoperative period, perceived caregiver strain was significantly increased. Psychological support for caregivers may be advisable, with timing of this support depending on diagnosis and patient-related factors.Trial registration: This manuscript was retrospectively registered on 05-04-2016 in the Netherlands Trial Register (NTR5932). http://www.trialregis

Objective Type D personality has been associated with various medical and psychosocial outcomes. Type D's underlying personality traits negative affectivity (NA) and social inhibition (SI) are hypothesized to either additively (NA + SI) or synergistically (NA ∗ SI) affect an outcome. As some of the methods used to assess a Type D effect have been criticized in the past, this study aimed to investigate for all commonly used methods their tendency of producing false positive Type D effect. Method 324,000 datasets were generated using a Monte Carlo Simulation. Each dataset was analyzed using various methods to assess a Type D effect. Each method's performance was assessed in terms of absolute bias and the percentage of false positive findings. An online application was developed where readers can easily experiment with this simulation. Results Our simulation showed that all commonly used methods risk producing false positive Type D effects. The only method with adequate false positive rates included the continuous NA and SI main effects, as well as their quadratic effects and their interaction. Conclusion All commonly used methods to assess a Type D personality effect showed inflated false positive rates in realistic simulation scenarios. All earlier research based only on these methods should be reconsidered.

Objective In research on Type D personality, its subcomponents negative affectivity (NA) and social inhibition (SI) are hypothesized to have a synergistic effect on various medical and psychosocial outcomes. As some methods to analyze Type D personality have been criticized, this study investigated whether these methods adequately detect a Type D effect. Method We used a simulation and two empirical illustrations to investigate each method's performance (bias, power and false positives) in detecting the Type D effect. Results Our simulation showed that the two most commonly used methods to assess the Type D effect (subgroup methods) were primarily picking up the presence of NA or SI main effects, indicating that these methods might falsely suggest synergistic Type D effects. Moreover, these methods failed to detect the combined presence of the NA and SI main effects, resulting in significant Type D effects when only one of the NA/SI main effects was present. The method that best detected Type D effects modeled the continuous NA/SI main effects and their statistical interaction in a regression analysis. Reanalysis of two empirical Type D personality datasets confirmed the patterns found in our simulation. Conclusion This study showed that Type D effects should be modeled with a continuous interaction approach. Other approaches showed either more bias, more false positive findings or lower power. We recommend against using subgroup approaches to operationalize Type D personality, as these methods are biased, regardless of whether the Type D effect is synergistic or additive in nature.

Contains fulltext : 208527.pdf (publisher's version ) (Open Access), Several approaches exist to model interactions between latent variables. However, it is unclear how these perform when item scores are skewed and ordinal. Research on Type D personality serves as a good case study for that matter. In Study 1, we fitted a multivariate interaction model to predict depression and anxiety with Type D personality, operationalized as an interaction between its two subcomponents negative affectivity (NA) and social inhibition (SI). We constructed this interaction according to four approaches: (1) sum score product; (2) single product indicator; (3) matched product indicators; and (4) latent moderated structural equations (LMS). In Study 2, we compared these interaction models in a simulation study by assessing for each method the bias and precision of the estimated interaction effect under varying conditions. In Study 1, all methods showed a significant Type D effect on both depression and anxiety, although this effect diminished after including the NA and SI quadratic effects. Study 2 showed that the LMS approach performed best with respect to minimizing bias and maximizing power, even when item scores were ordinal and skewed. However, when latent traits were skewed LMS resulted in more false-positive conclusions, while the Matched PI approach adequately controlled the false-positive rate.

Contains fulltext : 209367.pdf (publisher's version ) (Open Access), Background Psychological factors are associated with an increased risk of developing ischemic heart disease ( IHD ). Women more often report psychological factors, and sex and gender differences are present in IHD . In this meta-analysis we examine the risks of psychological factors for IHD incidence in women and men. We hypothesize that a broad range of psychological factors are related to a higher risk for incident IHD , with a higher risk for women. Methods and Results PubMed, EMBASE , and Psyc INFO were searched for studies assessing the risk between psychological factors and incident IHD . Psychological factors included depression, anxiety or panic disorder, social support, hostility, anger, personality (type D), type A behavior pattern, posttraumatic stress disorder, and psychological distress. In the primary analyses, 62 studies (77 separate reports) that included 2 145 679 women and 3 119 879 men and reported confounder-adjusted hazard ratios or relative risks were included. Pooled effect confounder-adjusted estimates from random-effects models showed that psychological factors (all combined) were associated with incident IHD in women (hazard ratio: 1.22; 95% CI , 1.14-1.30) and men (hazard ratio: 1.25; 95% CI , 1.19-1.31). No sex and gender differences were found for these pooled effect estimates ( P=0.547). Conclusions Psychological factors are associated with incident IHD in both women and men, but no significant differences were observed between women and men. IHD is predominantly being studied as obstructive coronary artery disease, which is more prevalent in men. Data are needed on psychological predictors and other manifestations of IHD such as coronary microvascular disease, which is more common in women.
