Establishing Criterion Scores for the Kansas Marital Satisfaction Scale and the Revised Dyadic Adjustment Scale

This study demonstrates the usefulness of the KMSS and RDAS in distinguishing between the maritally distressed and nondistressed. For conceptual and statistical clarity, many marital interaction and marital therapy research measures, use a single cutoff score. It was determined that the cutoff score is 17 for the Kansas Marital Satisfaction Scale (KMSS) and 48 for the Revised Dyadic Adjustment Scale (RDAS) for husbands, wives, and couples. An equivalency table of mathematical formulas is also presented, allowing the conversion of individual and couple scores from one measure of marital quality to another. It is now possible to convert a score from any one of a number of instruments (KMSS, RDAS, Dyadic Adjustment Scale, Marital Adjustment Test, Revised Marital Adjustment Test) to an equivalent score as measured by another instrument.
