Measuring Dyadic Adjustment: new scales for assessing the quality of marriage and similar dyads

This study reports on the development of the Dyadic Adjustment Scale, a new measure for assessing the quality of marriage and other similar dyads. The 32-item scale is designed for use with either married or unmarried cohabiting couples. Despite widespread criticisms of the concept of adjustment, the study proceeds from the pragmatic position that a new measure, which is theoretically grounded, relevant, valid, and highly reliable, is necessary since marital and dyadic adjustment continue to be researched. This factor analytic study tests a conceptual definition set forth in eariler work and suggests the existence of four empirically verified components of dyadic adjustment which can be used as subscales [dyadic satisfaction, dyadic cohesion, dyadic consensus and affectional expression]. Evidence is presented suggesting content, criterion-related, and construct validity. High scale reliability is reported. The possibility of item weighting is considered and endorsed as a potential measurement technique, but it not adopted for the present Dyadic Adjustment Scale. It is concluded that the Dyadic Adjustment Scale represents a significant improvement over other measures of marital adjustment, but a number of troublesome methodological issues remain for future research.
