Assessing the Impact of Relationship Profile Test Scores, Self-Identified Ethnic Group, and Gender on Adult Attachment Style.

Research shows that the subscales of the Relationship Profile Test (RPT) are related to adult attachment. Gender differences have been implicated, but findings are inconsistent in terms of replication. A limited amount of research has been conducted on ethnic differences in the context of interpersonal dependency. This study aims to bridge the gap in the literature in terms of using the RPT to predict attachment styles and to assess gender and ethnic group differences in RPT scores. Four samples from various treatment settings were combined to yield a heterogeneous group of ethnically diverse men and women (N = 470) with a mean age of 31.96. No gender differences were observed; however, ethnic differences were noted, with the RPT scales predicting unique variance in secure and insecure attachment styles. This study evidences the incremental validity of the RPT scales when predicting adult attachment style with consideration of ethnic group differences, which can help inform the treatment and assessment process.
