The KADS-6 is a self-report assessment instrument known for its ease application in assessing depression in young people. This study aimed to contribute to the validation of the Portuguese version of this tool and analyze its psychometric characteristics in comparison with other self-report instruments for depression in adolescents, in Portugal. Two samples were collected, a non-clinical group of in school youth (n=773; 52.4% male) and a clinical sample (n=134 youth; 44% male). Comparisons also used the Beck Depression Inventory (BDI-II) and the Children's Depression Inventory (CDI). Results: The factor analysis revealed the unidimensionality of the measure. The KADS-6 demonstrated good internal consistency (Cronbach's alpha) in both clinical (.74) and school (.80) samples. Its convergent validity with the BDI-II and CDI was r=.44; r=.61, respectively in the clinical sample and r=.60; r=.57 in the school sample. The KADS-6, a short and time effi cient instrument, showed good psychometric characteristics in terms of internal consistency and convergent validity in comparison with the BDI-II and the CDI. Given its ease of use and scoring, the KADS-6 could be considered for use in both school and clinical settings when addressing adolescent depression.

ResumoA Kutcher Adolescent Depression Scale (KADS-6) é uma medida de autorrelato, conhecida pela sua facilidade de aplicação na avaliação da depressão em jovens. Este estudo teve como objetivos contribuir para a validação da versão portuguesa desta ferramenta e analisar as suas características psicométricas em comparação com outros instrumentos de autorrelato para a avaliação da depressão em adolescentes, em Portugal. Foram recolhidas duas amostras, uma não clínica, formada por jovens em contexto escolar (n=773; 52,4% rapazes) e outra amostra clínica (n=134; 44% rapazes). Foram também utilizados o Beck Depression Inventory (BDI-II) e o Children's Depression Inventory (CDI). A análise fatorial revelou a unidimensionalidade da medida. A KADS-6 demonstrou boa consistência interna (alfa de Cronbach) nas amostras não clínica (.74) e clínica (.80). A validade convergente com a BDI-II e CDI foi, respetivamente, r = .44; r = .61 na amostra clínica e r = .60; r = .57 na amostra não clínica. Conclui-se que a KADS-6 mostrou boas características psicométricas em termos de consistência interna e validade convergente em comparação com o BDI-II e o CDI. Dada a sua facilidade de uso e interpretação, a KADS-6 pode ser considerada para uso em contexto escolar e em ambientes clínicos, para avaliar a depressão adolescente.

Optimism is associated with positive body image as it exerts it’s influence on positive body image through an expectancy judgment about the likelihood of acquiring a feared fat self. The study aims to understand and determine how individuals’ perceived optimism affects body image among young adults. The quantitative study uses an Ex Post Facto Correlational Design conducted on Indian young adults between 18-40 years old. The Body Image Avoidance Questionnaire (BIAQ) and the Positivity Scale were administered to the 508 participants through an online survey format. The quantitative analysis involved descriptive statistics and Pearson’s Correlation Coefficient in measuring the association between perceived optimism and body image. The study findings imply sufficient evidence to conclude a linear relationship between perceived optimism and body image because the correlation coefficient is significantly different from 0. The body image avoidance is weakly but negatively correlated with perceived optimism amongst the participants. This study aids and contributes to the repertoire of body image and positive psychology research. It also helps explore individual differences in the orbits of perceived optimism and body image as lockdown procedures helped alleviate the understanding of the complete psychological impact of the COVID-19 pandemic.
