Marital Decision Making Scale: Psychometric Properties

The psychometric properties of a revised version of the Marital Decision Making Scale (MDMS) were evaluated in this investigation. Sixty-eight couples served as participants. Distressed couples (n=34) were recruited from a community-based outpatient mental health clinic where they were seeking conjoint therapy for relationship problems; demographically matched nondistressed couples (n=34) were recruited from the community through a local survey research firm. The MDMS showed high internal consistency, test-retest reliability, interjudge agreement, and convergent and discriminant validity. A second independent sample of 60 couples (30 distressed couples and 30 nondistressed couples) was also recruited to cross-validate the results found with the first sample. Using the classification equation derived from the data for the first sample, the MDMS was found to reliably discriminate between distressed and nondistressed couples with this second sample. Potential clinical utility of the MDMS is reviewed.
