The Seven-Item Short Form of the Dyadic Adjustment Scale: Further Evidence for Construct Validity

Abstract

Two studies examine psychometric aspects of the seven-item version of the Dyadic Adjustment Scale (DAS) (Spanier, 1976). In Study 1, data from 148 heterosexual clients seeking marital therapy services and 122 heterosexual couples in the community were used to assess the criterion validity of the DAS-7. The measure differentiated between clinic and community participants and between marriages classified as distressed or adjusted based on the full DAS score. In Study 2, the reliability and convergent validity of the DAS7, when administered as a separate scale, was assessed in a community sample of 162 participants who were married or were in cohabiting heterosexual relationships. Obtained values were comparable to those reported in previous research in which the DAS-7 was obtained by extracting items from participants' full DAS. These results demonstrate that the DAS-7 is a psychometrically sound short form for assessing marital adjustment.
