Tested 2 issues concerning the widely used measure of marital satisfaction, the Dyadic Adjustment Scale (DAS): (1) whether the DAS is a measure of unidimensional satisfaction or a measure of multidimensional adjustment and (2) how well the DAS classifies spouses as distressed or nondistressed. Confirmatory factor analyses, maximal decomposition factor analysis, and classification analyses were conducted on archival data from 1,307 male and 1,515 female married persons (aged 17-80 yrs). A multidimensional model fit the data better than a 1-factor model. Satisfaction accounted for 19-25% of the variance in the DAS. The DAS classified distressed and nondistressed couples well. Discussion focuses on the appropriateness of using the DAS to classify couples, the inappropriateness of using satisfaction and adjustment as synonyms, and the questionable clinical significance of some DAS items.
