A Revision of the Dyadic Adjustment Scale for Use with Distressed and Nondistressed Couples: Construct Hierarchy and Multidimensional Scales

The existing research on the Dyadic Adjustment Scale (DAS) indicated that there were problems with some of the subscales and individual items. This study was designed to improve the instrument by following the standards of construct hierarchy. Through previous research and the analyses in this study, the subscales were found to contain some items that were homogeneous and others that were more heterogeneous. This problem was corrected by selecting out items that were homogeneous; 7jirst-order scales were created which were combined to create the 3 second-order concepts of consensus, satisfaction, and cohesion. With a sample of distressed and nondistressed couples, a series of confirmatory factor analyses was conducted. The factor analyses provided evidence for the construct validity of the new structure of the Revised DAS (RDAS) with the distressed, nondistressed, and total samples of this study, as well as with the sample from Spanier and ThompsonS ( I 982) study. Additional analyses correlating the RDAS with another popular
