Adaptação e validação da Family Dynamics Measure II para familiares de mulheres com câncer de mama

Abstract

The study aimed to adapt and validate the Family Dynamics Measure II for use with families of women with breast cancer. The process included translation, back-translation, semantic equivalence analysis by the instrument's main author, semantic analysis per sample of the target population, content validity analysis by judges and evaluation of psychometric properties of the scale applied to 251 relatives of women with breast cancer. It was obtained an adapted version with good reliability (α=0.90); factor analysis did not confirm the theoretical dimensionality of the original instrument; correlations with the Hospital Anxiety and Depression Scale were inverted, and from low to moderate intensity. The scale was considered valid for use in Brazil. Further studies are suggested to strengthen the evidence.
