This study investigated the positive and negative predictors of depression, anxiety, stress, and flourishing among Brazilian adults during the first wave of the COVID-19 pandemic. The sample consisted of 665 adults (women: 77%), aged between 18 and 79 years (M = 36.70; SD = 13.12). Participants completed a sociodemographic questionnaire, the Brief-COPE Inventory; the Depression, Anxiety and Stress Scale; the PERMA Profiler; the Acceptance and Action Questionnaire-II; and the Meaning-Centered Coping Scale. Multiple regression analyses indicated that avoidance coping, and psychological inflexibility were significant predictors of stress, anxiety, and depression. Age, flourishing, and perceived physical health acted as protective factors, with significant differences between participants with and without prior psychological diagnoses. Meaning-centered coping predicted flourishing in both groups. These findings suggest that interventions should address prior diagnoses, and foster flourishing dimensions, alongside adaptive coping strategies, including meaning-centered coping.

This study adapted and examined the psychometric properties of the Youth Life Orientation Test (YLOT)-a measure to evaluate dispositional optimism and pessimism-in a Brazilian sample of children and adolescents aged between 5 and 16 years. The factor structure, reliability, convergent validity, and invariance of the YLOT were evaluated within and across four age groups (N1 = 266, N2 = 246, N3 = 211, and N4 = 253). Participants were 976 students (51.9% girls) who answered the YLOT and subjective well-being measures and 350 parents (51.6% female) who answered a parent-report measure of optimism. Confirmatory factor analyses suggested an oblique two-factor model best fit the data, indicating that optimism and pessimism are independent factors. These factors demonstrated adequate reliability and convergent validity evidence with well-being measures. Additionally, scalar invariance was obtained, and latent mean analyses indicated optimism decreases and pessimism increases in participants from 5 to 13 years old. These results support the use of YLOT in Brazil. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Este estudo objetivou adaptar as Tarefas Preditoras de Otimismo em Crianças (TAPOC) para uso em tablet e investigar evidências de validade da versão informatizada. Além disso, investigaram-se o nível de otimismo das crianças avaliadas e possíveis diferenças entre os sexos, tipos de escolas e cidades. O estudo foi realizado em duas etapas, informatização do instrumento e estudo de evidências de validade. Na primeira,

43; DP=1,78) de dados oriundos de pesquisas realizadas no Rio Grande do Sul. Foi conduzida uma análise fatorial confirmatória para avaliar a qualidade de ajuste do modelo. A fidedignidade foi estimada por meio do alfa de Cronbach e ômega de McDonald. Os resultados indicaram que as alterações favoreceram a obtenção de bons índices de ajuste do modelo após a exclusão de 18 itens e retirada da dimensão Não Violência. Houve incremento na consistência interna
