title: Validity of the Spanish version of the Inventory of Interpersonal Problems and its use for screening personality disorders in clinical practice.
abstract: We studied the reliability and validity of two versions (64 items and 32 items) of the Spanish translation of the Inventory of Interpersonal Problems (IIP-64 and IIP-32) and their usefulness as screening instruments for personality disorders in a sample of 190 outpatients and 66 healthy subjects. Patients were assessed using the IIP-64 and IIP-32, the Structured Clinical Interview for DSM-IV Axis II Personality Disorder diagnoses, and the Global Assessment of Functioning. The internal consistency and test-retest reliability were satisfactory. As theoretically predicted, factor analysis produced eight factors, and multidimensional scaling indicated the two dimensions of affiliation and dominance. Finally, a cutoff point of 87 for the IIP-64 showed 87% sensitivity and 85% specificity, whereas a cutoff point of 44 for the IIP-32 showed 82% sensitivity and 75% specificity. The Spanish versions of the IIP-32 and the IIP-64 are valid instruments for assessing interpersonal problems and for screening personality disorders in clinical practice.
