RESUMO
Abstract Introduction Experiencing trauma may entail psychopathological consequences, but also changes considered to be positive (i.e., posttraumatic growth). For positive change to occur, an impact on the beliefs of individuals is required, which may be measured through the Core Beliefs Inventory (CBI). The objective of this study was to validate the Brazilian Portuguese version of the CBI. Methods A total of 248 university students (65.7% female) answered the following assessment instruments: sociodemographic data sheet, Posttraumatic Growth Inventory (PTGI), Posttraumatic Symptoms Checklist - Clinician Version (PCL-5) and the CBI. Psychometric properties of the CBI were assessed by conducting an exploratory factor analysis through a principal component analysis with varimax rotation. Internal consistency (Cronbach's α) and convergent validity (Pearson correlation between instruments) were also investigated. Results The total scale showed adequate internal consistency (α = 0.83). A single factor solution explained 42.63% of the variance of the CBI. Significant correlations were found between CBI and PTGI, and between CBI and PCL-5. Conclusion The psychometric properties indicated adequate internal consistency and construct validity of the Brazilian Portuguese version of the CBI.
Resumo Introdução Experimentar um trauma pode levar a consequências psicopatológicas, mas também a alterações consideradas positivas (ou seja, crescimento pós-traumático). Para que mudanças positivas ocorram é necessário um impacto nas crenças dos indivíduos, o que pode ser medido através do Core Beliefs Inventory (CBI). O objetivo deste estudo foi validar a versão em português do Brasil do CBI. Métodos Um total de 248 universitários (65,7% mulheres) responderam aos seguintes instrumentos de avaliação: ficha sociodemográfica, Inventário de Crescimento Pós-Traumático (Posttraumatic Growth Inventory - PTGI), Lista de Verificação de Sintomas Pós-Traumáticos - Versão Clínica (Posttraumatic Symptoms Checklist - Clinician Version - PCL-5) e CBI. As propriedades psicométricas do CBI foram avaliadas a partir de análise fatorial exploratória através de análise de componentes principais com rotação varimax. A consistência interna (α de Cronbach) e a validade convergente (correlação de Pearson entre os instrumentos) também foram investigadas. Resultados A escala total apresentou consistência interna adequada (α = 0,83). Uma solução de fator único explicou 42,63% da variação do CBI. Correlações significativas foram encontradas entre CBI e PTGI e entre CBI e PCL-5. Conclusão As propriedades psicométricas indicaram consistência interna adequada e validade de construto da versão em português do Brasil do CBI.
