Abstract
This study assessed the construct validity of the Relationship Profile Test (RPT; Bornstein & Languirand, Citation2003) with a substance abuse sample. One hundred-eight substance abuse patients completed the RPT, Experiences in Close Relationships Scale–Short Form (Wei, Russell, Mallinckrodt, & Vogel, Citation2007), Personality Assessment Inventory (Morey, Citation1991), and Symptom Checklist–90–Revised (Derogatis, Citation1983). Results suggest that the RPT has good construct validity when compared against theoretically related broadband measures of personality, psychopathology, and adult attachment. Overall, health dependency was negatively related to measures of psychopathology and insecure attachment, and overdependence was positively related to measures of psychopathology and attachment anxiety. Many of the predictions regarding RPT detachment and the criterion measures were not supported. Implications of these findings are discussed.
