Three related studies are presented focusing on the development of a short 32-item version of the Inventory of Interpersonal Problems (IIP). Study 1 presents the procedures for item selection on the IIP short version; Study 2 presents a confirmatory analysis of the IIP short version on an independent sample; and Study 3 provides preliminary normative (general population and out-patient) data and additional evidence of the psychometric properties of the IIP short form. The results suggest that the short version sacrifices little compared to the original 127-item version in terms of its psychometric properties while being considerably more convenient for routine clinical practice.
