Validity and reliability estimates of the interpersonal relationship scale

The study reports on the refinement of the Interpersonal Relationship Scale, a new semantic differential measure for assessing interpersonal relationship adjustment. The 120 item scale was designed for use in marital and other dyadic relationships. Despite widespread criticism of the concept of adjustment, the study proceeds from the position that a new measure which is theoretically grounded, relevant, valid, and reliable is necessary since marital and other relationships continue to be researched. In this study, predictive, content, concurrent, and construct validity as well as high scale reliability is reported utilizing a sample of 94 counseling and non-counseling subjects. It is concluded that the IRS is instrumental in assessing interpersonal relationship adjustment, but some methodological issues still remain unresolved.
