The Italian Version of the Inventory of Interpersonal Problems Personality Disorders Scales (IIP-47): Psychometric Properties and Clinical Usefulness as a Screening Measure

The Inventory of Interpersonal Problems 32 (IIP-32; Horowitz, Aiden, Wiggins, & Pincus, 2000) is a brief, 32-item, self-report questionnaire used to screen for interpersonal problems. While studies of the IIP-32's psychometric properties have been conducted in other nations, and studies have examined the psychometric properties of the IIP-32's circumplex structure, no studies have examined the factor-analytic structure in the United States since the original standardization sample. The aim of this study was to examine the psychometric properties of the IIP-32 in American college women for the first time and explore its structural validity as a circumplex measure and its concurrent validity with measures of attachment. The current study found that internal consistency estimates and interscale correlations were generally high and confirmed the proposed circumplex structure. In addition, concurrent validity was evidenced by confirming theorized relations between attachment and the IIP-32 subscales. However, IIP-32 subscales were limited with regard to divergent validity.

To encourage screening for personality disorders (PDs), we developed (in previous work) self-report scales for PDs using the Inventory of Interpersonal Problems (IIP). The combined score from three of the scales—inter-personal sensitivity, interpersonal ambivalence, and aggression—requiring 15 items (IIP-15) did the best job of distinguishing between respondents with any versus no PD. The goals for the present work were (a) to cross-validate the IIP-15 by examining its performance using receiver operating characteristics (ROC) analyses in a new sample (N = 410), and (b) to investigate the utility of a brief three-item variant (IIP-3). The present results again documented the good operating characteristics of the IIP-15. Sensitivity, specificity, and positive and negative predictive values were all above. 70. The operating characteristics of the IIP-3 were nearly as good despite its brevity and support its use as an initial screen for PDs.
