Abstract
This study aimed to build and verify validity evidence of a marital quality assessment scale (EQC) for the Brazilian population. The items were first evaluated by an expert panel and members of the target population. The preliminary version of the EQC consisted of 28 items evaluating five dimensions: satisfaction, commitment, intimacy, sexuality, and affection. Participants were 655 people who had been in a romantic relationship and in co-habitation with the partner for at least six months. The questionnaire also included instruments on sociodemographic data, and marital adjustment (RDAS-P), satisfaction (RelAS), quality (Aquarela-R), and conflict (CRBQ). Confirmatory factor analysis, internal consistency, and correlation analyses were performed. The EQC model was well fitted to the data, had good internal consistency, and correlated with the other scales in the expected directions. We concluded that the instrument showed adequate validity evidence for administration in the Brazilian context.
