ABSTRACT
This study sought to confirm the structure and to investigate the psychometric properties of an experimental Portuguese version of the York Cardiac Beliefs Questionnaire (YCBQ) in a general population sample. It also set out to identify the prevalent misconceptions in the community and to assess the differences according to socio-demographic characteristics. It involved a cross-sectional survey in which both test and validation samples were collected (n = 476), including participants aged between 18 and 40, recruited via e-mail and social networks. The Confirmatory Factor Analysis on both samples suggested a shorter, three factor version of the YCBQ. Also, misconceptions differed significantly according to sociodemographic variables. The validation of the YCBQ for samples in the community constitutes an important starting point to promote research on misconceptions held in the community by specific groups, as well as to provide key points for health promotion.

Este estudo teve como objetivo confirmar a estrutura e investigar as propriedades psicométricas de uma versão experimental portuguesa do York Cardiac Beliefs Questionnaire numa amostra da população geral; identificar as crenças erróneas mais fortes na comunidade; e avaliar as diferenças de acordo com características sociodemográficas. Trata-se de um estudo transversal com uma amostra de teste e outra de validação, incluindo um total de 476 participantes, com idade entre 18 e 40 anos, recrutados via e-mail e nas redes sociais. A Análise Fatorial Confirmatória em ambas as amostras indicou uma versão reduzida do YCBQ de três factores. As crenças erróneas diferiram significativamente de acordo com as variáveis sociodemográficas. A validação do YCBQ para amostras da comunidade constitui um importante ponto de partida para promover a investigação sobre crenças erróneas em grupos específicos da comunidade, assim como fornecer indicadores relevantes para a promoção da saúde.
