The Dyadic Relationships Test: Creation and Validation of a Model-Derived,Visual-Verbal Instrument to Evaluate Couples Part I of II

Abstract

In Part I of this article, background and rationale for the construction of a Selfhood model-derived visual-verbal Dyadic Relationships Test (DRT) is presented. Results from studies covering its reliability and verification of its psychometric properties are presented. Construct validity was evaluated through research with competing theoretical models. In Part II, results from studies are reported through discriminant and concurrent validity analyses in adoptive and traditional couples. A revision evaluated its construct validity with measures of negotiation, intimacy, and communication, and through relational and emotional life at different stages of the life cycle, including empty nest and retirement. Results from these studies tend to support the psychometric properties of this instrument and, indirectly, the validity of the Selfhood model underlying its construction.
