The Dyadic Adjustment Scale (DAS) is a self-report instrument measuring marital satisfaction, which has been widely used in different cultures. In Spain, there are to date no studies analysing the psychometric properties of the scale in functional and dysfunctional couples, nor performing independent factor analysis of men and women's data. The objective of this study is to determine some psychometric properties of a Spanish DAS version on a sample of 915 participants: 403 who requested couple therapy, and 512 who did not request therapy. Results support the reliability of the instrument for both subsamples. The confirmatory factor analysis showed a four-factor internal structure that corresponds to the one proposed by the author of the original scale. Furthermore, the Spanish DAS has high discriminant power between both subsamples, and presents as a valid and reliable instrument to measure marital quality in Spanish couples who request couple therapy and those who do not request it.
