Objective: Fear of negative evaluation (FNE) is a key trait of social anxiety and has been linked to isolation and low self-esteem. Impulsivity has been shown to amplify the risk of socially anxious individuals engaging in risky behaviors such as suicidal behaviors; yet little research has examined associations between FNE and suicidality or the relationship between FNE and impulsivity. Participants/ Methods: This study tested whether FNE was associated with suicidal ideation in a sample of 1,816 college students from 10 universities. Analyses also examined whether impulsivity-like traits moderated the relationship between FNE and suicidal ideation. Results: Results showed that FNE was significantly associated with suicidal ideation and the positive association between FNE and suicidal ideation was strongest among individuals with higher negative urgency and lower perseverance. Conclusions: These findings highlight FNE as an important risk factor of suicidal ideation in college students and illuminates potential influence of impulsivity on this relationship.

The present work aimed to extend the evidence of the structure validity of the Ruminative Thought Style Questionnaire (RTSQ) 15-item version testing: (1) the structure of two competing models (i.e., four-factor correlated model vs a second-order factor model); (2) the measurement invariance of the final model across four countries (U.S., Spain, Argentina, and the Netherlands) and gender groups (male and female); and (3) the invariance across three assessment waves in a subsample of Spanish youths. Participants were college students (mean age = 20.87, SD = 4.47) from the U.S. (n = 1875; 67.1% of females), Spain (T1, n = 732, 63.9% females; T2, n = 370, 71.6% females: T3, n = 307, 60.6% females), Argentina (n = 368, 65.6% females) and the Netherlands (n = 295, 74.8% females). Confirmatory Factor Analyses supported both correlated factors and second-order factor structure in the whole sample. Due to similar fit indices being observed for both models, and considering the theoretical and practical advantages, we kept the second-order model to examine its invariance across groups and time. Measurement invariance analyses showed that the second-order model was invariant across countries, gender, and over time. Comparisons of the total mean score and the subfacet mean scores (i.e., Repetitive Thoughts, Counterfactual Thoughts, Problem-focused Thoughts, and Anticipatory Thoughts) reveled only small differences across country and gender groups. The present work extends the structural validity evidence of the RTSQ, and provides the first evidence concerning its longitudinal stability across time., Author(s): Verónica Vidal-Arenas [sup.1] , Manuel I.

While there is evidence that histories of adverse childhood experiences (ACEs) are common in university students and are associated with an increased risk of mental health difficulties, current research has limited geographic and cross-cultural representation. Comparing ACEs across diverse contexts using a standardized measure can illuminate geographic and sociocultural similarities or differences in exposure. The present study aimed to assess ACE exposure and its relationship with mental health symptoms in university students from seven countries. We sampled 5945 university students from the United States, Canada, England, South Africa, Spain, Argentina, and Uruguay. Participants completed the Adverse Childhood Experiences International Questionnaire (ACE-IQ) and the Inventory of Depression and Anxiety Symptoms (IDAS). Most participants (94.8%) reported exposure to at least one type of ACE and 61% reported exposure to four or more types. Repeated exposure to at least one ACE was reported by 70.2% and repeated exposure to at least four ACEs was reported by 21.2%. Spanish students had significantly lower ACE exposure than other students. Cumulative ACE exposure was significantly higher among students in lower income countries, but when repeated exposure was considered these differences fell away. For the total sample, cumulative ACE exposure was significantly associated with severity of depression symptoms, anxiety symptoms, and suicidality. Findings indicate that universities globally should be guided by a trauma-informed approach that recognizes students as a psychologically vulnerable group carrying a long-standing burden of childhood adversity., Author(s): Debra Kaminer [sup.1] , Adrian J.

We report measurements of the Meissner screening profile in a Nb (300 nm)/ Al 2 O 3 thin film using 8 Li β -detected nuclear magnetic resonance (β -NMR). The NMR probe 8 Li was ion-implanted into the Nb film at energies ≤ 20 keV, corresponding to mean stopping depths comparable to Nb 's magnetic penetration depth λ. 8 Li 's strong dipole–dipole coupling with the host 93 Nb nuclei provided a "cross-relaxation" channel that dominated in low magnetic fields, which conferred indirect sensitivity to the local magnetic field via the spin-lattice relaxation (SLR) rate 1 / T 1. From a fit of the 1 / T 1 data to a model accounting for its dependence on temperature, magnetic field, and 8 Li + implantation energy, we obtained a magnetic penetration depth λ 0 = 51.5(22) nm, consistent with a relatively short carrier mean-free-path ℓ = 18.7(29) nm typical of similarly prepared Nb films. The results presented here constitute an important step toward using 8 Li β -NMR to characterize bulk Nb samples with engineered surfaces, which are often used in the fabrication of particle accelerators.

Individualism and collectivism are dimensions of cultural variation thought to shape differences in emotion regulation tendencies, yet research to date has examined these cultural dimensions as country-level features, emphasizing variability across nations. The present study takes the approach of examining cultural differences within nations as predictors of emotion regulation strategies, shifting the perspective instead to individual differences. This present study aimed to address how individual endorsement of individualism-collectivism (i.e. prioritizing individual versus group goals) and vertical-horizontal attitudes (preference for hierarchy versus equality) are associated with use of emotion regulation strategies (i.e., reappraisal and suppression) among college students from seven countries (n = 5,900; female = 70.80%). Overall, we found that individual differences in individualism-collectivism and vertical-horizontal attitudes had strong connections with young adults' emotion regulation styles. Results of our multivariate (i.e., all variables were simultaneously examined) regression model revealed: a) higher endorsement of horizontal individualism and horizontal collectivism were associated with higher use of reappraisal strategies; b) higher endorsement of horizontal individualism and vertical collectivism were associated with higher use of suppression strategies; while higher endorsement of horizontal collectivism was associated with lower use of suppression strategies. A multi-group model supported the generalizability of these associations across countries. These findings demonstrate the value of approaching cultural differences in emotion regulation from an individual differences framework, and not assuming country-level differences are representative of individuals' affective experiences. Further work is needed examining models within-country to examine cultural variation in individualism vs collectivism compared to country-level norms. [ABSTRACT FROM AUTHOR]

The 15-item Distress Tolerance Scale (DTS) is a widely used psychometric measure with evidence generally supporting its reliability and validity. However, limitations related to its ordinal response format and lack of cross-cultural comparisons have yet to be investigated using appropriate methods. The Partial Credit Rasch model was used to evaluate and enhance the psychometric properties of the DTS using responses from 2550 adult participants from the United States of America (USA), England, Canada, South Africa, Spain, and Argentina. The initial poor fit of the DTS to the Rasch model was improved by removing one item and combining locally dependent items into three testlets. These modifications resulted in the best fit of the 14-item DTS to the Rasch model for all the countries in our study, providing evidence of unidimensionality, high reliability and invariance across countries, meditation practice, and gender. Meeting the expectations of the Rasch model permitted the development of ordinal-to-interval conversion algorithms derived from person estimates of the Rasch model. Using the ordinal-to-interval conversion algorithms published in this article, ordinal DTS scores can be transformed into interval-level data, enhancing the precision of this scale for future research and clinical use across people from the six countries in this study and across the English and Spanish versions of the 14-item DTS.

Stigma relating to substance use disorders is one of the many barriers to enrolling in substance use treatment. Stigma is also related to poorer substance use treatment outcomes, yet few studies of substance use and substance use treatment outcomes include measures of stigma. Stigma is a multi-level experience occurring as a result of discrimination within a systematic power structure promoting inequities among marginalized populations. Several domains of stigma are manifested among individuals seeking treatment for a substance use disorder, with internalized stigma being the most commonly measured. The current paper is a narrative review of measures that have been developed to measure internalized stigma related to substance use in treatment settings. Measures of stigma (n = 8) in substance use treatment settings were identified using PubMed and PsycINFO databases. The review identified various strengths of existing measures, including a broad range of measures with mostly excellent internal consistency. The review also identified limitations including the general lack of consideration for multiple domains and intersecting forms of stigma, samples with limited racial and ethnic diversity, and the lack of assessments of polysubstance use. The development of measures of the stigma that assess multiple domains of stigma and that are tested in a wide range of substance use treatment settings with racially and ethnically diverse participants is needed. This is of particular importance because stigma remains a crucial barrier to the successful initiation and completion of substance use treatment. [ABSTRACT FROM AUTHOR]

Psychological need satisfaction and need frustration, proposed by self-determination theory, may serve as conditions that foster health-promoting and health-impairing behaviors related to cannabis use. In the present study, we examined the measurement model of psychological need satisfaction and need frustration and their associations with cannabis protective behavioral strategies use, negative cannabis-related consequences, and cannabis use severity. Data were from 1394 college students from 10 universities across the U.S. who reported past-month cannabis use. A higher-order factor model representing general psychological need satisfaction and need frustration provided a good fit to the data. Regressing the three observed cannabis outcome variables onto these higher-order latent factors, we found that greater need satisfaction was associated with more frequent cannabis protective behavioral strategies use and fewer negative cannabis-related consequences. Greater need frustration was associated with greater negative cannabis-related consequences and cannabis use severity. Further, an interaction effect between need satisfaction and need frustration emerged for each cannabis outcome such that greater need satisfaction attenuated the associations between need frustration and cannabis outcomes and greater need frustration strengthened the associations between need satisfaction and cannabis outcomes. Implications for the roles of need satisfaction and need frustration in cannabis use and future intervention development are discussed. [ABSTRACT FROM AUTHOR]
