Assessment of Rorschach Dependency Measures in Female Inpatients Diagnosed With Borderline Personality Disorder

The psychometric properties and predictive validity of the Dependency Index (DI; Hilsenroth & Bornstein, 2002) and the Rorschach Oral Dependency Scale (ROD; Masling, Rabie, & Blondheim, 1967) were examined to determine if these implicit measures of dependency predict observable attachment-seeking behavior in 66 female inpatients diagnosed with borderline personality disorder. Results indicate that both scales produce excellent reliability estimates. The DI and ROD yield adequate base rates, and the distributions of scores approximate normal distributions. The DI was predictive of nursing staff observation of positive attachment/treatment compliance (r = .28, p = .02) but not excessive isolation. By contrast, the ROD predicted positive attachment/treatment compliance (r = .38, p = .002) and excessive isolation (r = –.35, p = .004). Texture responses predicted excessive isolation (r = –.25, p = .05). Discriminant validity was supported when neither dependency measure predicted hostile interactions or selfdestructive behaviors. Hierarchical regression analyses revealed that the RODdemonstrated incremental validity over the DI and select Comprehensive System (Exner, 1993) variables associated with dependency.
