Construct validity of the relationship profile test: three-year retest reliability and links with core personality traits, object relations, and interpersonal problems.
The Relationship Profile Test (RPT; Bornstein & Languirand, 2003) is a 30-item self-report measure of destructive overdependence, dysfunctional detachment, and healthy dependency. Previous research has shown that the 3 RPT subscales have adequate internal consistency, good retest reliability over 23 and 85 weeks, and good convergent and discriminant validity with respect to measures of attachment style, relatedness, gender role, self-concept, alexithymia, locus of control, need for approval, and life satisfaction. In this investigation, we assessed the 3-year retest reliability of RPT scores in a northeastern liberal arts college student sample (Study 1) and evaluated the convergent and discriminant validity of RPT scores in a southern university sample (Study 2). Results generally supported the long-term stability and convergent and discriminant validity of RPT scores but also pointed to some limitations of the measure. We discuss implications of these results and describe future research directions.
