The first year of the COVID-19 pandemic constituted a major life stress event for many adolescents, associated with disrupted school, behaviors, social networks, and health concerns. However, pandemic-related stress was not equivalent for everyone and could have been influenced by pre-pandemic factors including brain structure and sleep, which both undergo substantial development during adolescence. Here, we analyzed clusters of perceived stress levels across the pandemic and determined developmentally relevant pre-pandemic risk factors in brain structure and sleep of persistently high stress during the first year of the COVID-19 pandemic. We investigated longitudinal changes in perceived stress at six timepoints across the first year of the pandemic (May 2020–March 2021) in 5559 adolescents (50 % female; age range: 11–14 years) in the United States (U.S.) participating in the Adolescent Brain Cognitive Development (ABCD) study. In 3141 of these adolescents, we fitted machine learning models to identify the most important pre-pandemic predictors from structural MRI brain measures and self-reported sleep data that were associated with persistently high stress across the first year of the pandemic. Patterns of perceived stress levels varied across the pandemic, with 5 % reporting persistently high stress. Our classifiers accurately detected persistently high stress (AUC > 0.7). Pre-pandemic brain structure, specifically cortical volume in temporal regions, and cortical thickness in multiple parietal and occipital regions, predicted persistent stress. Pre-pandemic sleep difficulties and short sleep duration were also strong predictors of persistent stress, along with more advanced pubertal stage. Adolescents showed variable stress responses during the first year of the COVID-19 pandemic, and some reported persistently high stress across the whole first year. Vulnerability to persistent stress was evident in several brain structural and self-reported sleep measures, collected before the pandemic, suggesting the relevance of other pre-existing individual factors beyond pandemic-related factors, for persistently high stress responses. • The paper reports findings from the ABCD study® on U.S. youth across the first COVID-19 pandemic year: May 2020 – March 2021. • 5% of adolescents reported persistently high stress levels during the first year of the pandemic. • Persistent stress was linked to pre pandemic brain structure, sleep difficulties, and more advanced puberty stages. • The findings inform preventive and treatment approaches for persistent stress during major life stress events like pandemics.

Emotion regulation plays a crucial role in affective functioning. One of the most commonly used measures of emotion regulation is the Emotion Regulation Questionnaire (ERQ), a 10-item self-report measure assessing frequency of use of two common emotion regulation strategies: cognitive reappraisal and expressive suppression. In this study, we aimed to optimize the utility of the ERQ for time-pressured settings by introducing and validating a 6-item short form called the Emotion Regulation Questionnaire-Short Form (ERQ-S). General community (N = 508) and college student (N = 245) samples from the United States completed online surveys containing a range of psychometric self-report measures. For each sample, we examined the factor structure, internal consistency, and concurrent validity of the ERQ-S. Our confirmatory factor analyses supported the intended 2-factor structure of the ERQ-S (cognitive reappraisal and expressive suppression factors), with all items loading well on their intended factor in both samples. As expected, the ERQ-S correlated highly with the ERQ. A profile of low cognitive reappraisal use and high expressive suppression use on the ERQ-S was significantly associated with higher levels of emotion regulation difficulties, alexithymia, and affective symptoms. We did not examine psychometric performance in a clinical sample, or other cultural groups outside the US. All concurrent validity markers were self-report questionnaires. Our data suggest that the ERQ-S successfully retains the psychometric strengths of the ERQ. The shorter format of the ERQ-S should therefore help to optimize the measurement of emotion regulation in time-pressured settings. • The ERQ is the most widely used self-report measure in the emotion regulation field. • In this paper we introduce and validate a 6-item short form called the ERQ-S. • Across two samples, the ERQ-S displayed strong validity and reliability. • The ERQ-S has good psychometrics as a measure of reappraisal and suppression. • Its introduction should help to further enable assessments in time-pressured settings.

Background: Ever since alexithymia was defined in the 1970s, robust associations have been observed between alexithymia and a variety of symptoms of psychopathology. Alexithymia is now widely regarded as an important transdiagnostic risk factor, and it is frequently assessed in clinical and research settings. However, despite this strong interest, it remains unclear exactly why (i.e., by which mechanisms) alexithymia is linked to psychopathology. In this paper, we hypothesise that alexithymia is linked to affective disorder symptoms because alexithymia impairs people's ability to regulate their emotions, and we empirically test this hypothesis.Method: We administered a battery of psychometric measures to 501 adults in the United States, and examined the direct and indirect effects between alexithymia (Perth Alexithymia Questionnaire), emotion regulation ability (Perth Emotion Regulation Competency Inventory), and affective disorder symptoms (Depression Anxiety Stress Scales-21).Results: In the Pearson bivariate correlation matrix, alexithymia, emotion regulation difficulties, and affective disorder symptoms were all significantly correlated. In the modelling of direct and indirect effects, alexithymia was indirectly associated with affective disorder symptoms through emotion regulation difficulties (no significant direct effect).Limitations: Our online survey data were all self-report data and cross-sectional. Future longitudinal work would be beneficial.Conclusions: Our findings support contemporary theorising that alexithymia is linked to affective disorder symptoms via emotion regulation difficulties. These results help to clarify the mechanisms by which alexithymia may predispose people to affective disorder symptoms, and highlight the importance of considering the roles of alexithymia and emotion regulation in case conceptualisations and treatment planning.

Background: Increasing knowledge on suicide prevention has been shown to be important for suicide prevention. This paper exams the accomplishment of research on suicide and examine how those research activities contribute to the change of suicide rates.Methods: Data of the publications relating to suicide from 1990 to 2018 were retrieved from the Web of Science and Scopus. Bibliographic information was analyzed and the relationships between suicide rates with the number of publications per million population and the average article citations per year were examined.Results: From 1990 to 2018, globally, publications on suicide have increased significantly. The United States ("USA") had the greatest number of publications. Research collaborations among different countries/regions have been flourishing and multinational centers have become more common than ever. Nonetheless, in some countries/regions with high rates of suicide, suicide research was scarce. It was found that the number of publications per million population and the average article citations per year were negatively correlated with the suicide rates at the global level (r = - 0.96, p < 0.001; r = -0.91, p < 0.001, respectively), but not in the higher SDI regions (r = -0.05, p = 0.81; r = 0.02, p = 0.91, respectively). Furthermore, research focusing on suicide intervention was also relatively limited.Limitation: The origins of the publications were only based on the corresponding authors' regions.Conclusions: There is significant imbalance in the amount of research effort especially in the regions with high suicide rates. In the higher socioeconomic level regions, the quantity and quality of publications sometimes do not transpire in the reduction of suicide rates. A better connection between the fundamental and practical suicide research should be established. More resources should be made available to the low- and middle-income countries/regions with higher suicide risks, then the effect of suicide prevention might be much more significant.

Background Minorities comprise more than one third of the U.S., and research on the correlates and causes of depression, anxiety, and other mental illnesses have yielded mixed results in minority groups necessitating an understanding of causes and correlates of health. Thus, the aim of this paper is to evaluate the relationship between minority status, contextual factors, and lifetime Generalized Anxiety Disorder. Methods Logistic regression models were implemented, comparing immigrants to their American-born counterparts as well as to American-born Whites. Results Foreign-born Afro-Caribbeans exhibited lower rates of lifetime GAD. A lower percentage of foreign-born minorities met the criteria for GAD as compared to their American-born counterparts, and all racial and ethnic groups met the criteria for lifetime GAD at a lower rate as compared to American-born Whites. Discussion By using theory proactively and including contextual factors, this multi-faceted approach to health disparities research yielded findings which both supported historic beliefs but created opportunities for supplemental research looking at immigrants and GAD. Key findings were that health lifestyle choices and exposure to discrimination significantly affected the chance of having GAD. Nativity was protective; however, its effect was ameliorated by exposure to discrimination or engagement in alcohol abuse. Thus, this study offers practical insight into environmental factors for clinicians caring for racial and ethnic minorities diagnosed with GAD. [ABSTRACT FROM AUTHOR]

Abstract: Introduction: Chronic insomnia, a public health crisis affecting 10–15% of the U.S. population and costing billions of dollars annually, typically presents with one or more comorbid psychiatric or organic conditions. Historical classification of chronic insomnia as “secondary” to a presenting comorbid condition has resulted in under-recognition and under-treatment of both the insomnia and comorbid condition(s). Though critical in any model of comorbid disease management, chronic insomnia receives little, if any, public policy attention. Method: We conducted a systematic review of recent empirical studies, review papers, books, government documents, press releases, advertisements, and articles pertaining to the classification, epidemiology, treatment, and physiology of sleep, insomnia, and comorbid conditions. Data were located primarily through MEDLINE, PsycINFO, SCOPUS, and PUBMED databases. Objective and results: Our goal was to provide an overview of the systems for classifying insomnia and available epidemiological data, and to review theoretical models regarding the etiology and maintaining factors of chronic insomnia along with research on the complex, bidirectional associations between chronic insomnia and various affective (and other) conditions. Conclusions: After thorough review of the literature, we propose several public policy measures as an initial step in managing chronic insomnia in the United States. These include introducing a nation-wide multi-modal educational and awareness campaign titled “Sleep America;” increasing the availability and demand for behavioral sleep medicine — the initially preferred treatment approach; and increasing the use of monitoring and enforcement activities by regulatory authorities to curtail false and misleading claims by sponsors of supplements or treatments for insomnia. Through the adoption of such measures, we hope to galvanize a national interest in healthy sleep and the evidence-based treatment of chronic insomnia. [Copyright &y& Elsevier]
