Assessing Relationship Satisfaction: Development and Validation of the Dyadic-Familial Relationship Satisfaction Scale

Abstract

Relationship satisfaction can be defined as a complex construct that is composed of at least two different dimensions: dyadic and familial. The aim of this research was to develop and validate a scale that can measure these different dimensions of relationship satisfaction, the Dyadic-Familial Relationship Satisfaction Scale. The validity and reliability of this scale were examined through explorative and confirmative factor analyses. Known groups validity was evaluated by comparing the scores obtained on the scale by participants who belonged to clinical and nonclinical couples. Consistent with our predictions, the Dyadic-Familial Relationship Satisfaction Scale was composed of two dimensions (dyadic and familial). It showed high reliability and good convergent and discriminant validity (estimated by composite reliability and the average variance extracted). The scale showed good known groups validity. Some gender differences were found with respect to both the dyadic and the familial subscales. Results suggest that this instrument could be usefully applied in the relationship satisfaction field of research and intervention.
