Structure and Change of the IIP-D Pre- and Postpsychotherapy

The structure and change of the Inventory of Interpersonal Problems in the German Circumplex version (IIP-D; Horowitz, Strauss, & Kordy, 2000 ) were examined in a study of 393 Swiss psychotherapy outpatients. Replicating results by Vittengl, Clark, and Jarret (2003) , interpersonal problems showed a three-factor structure (Interpersonal Distress, Love, and Dominance), with the latter two factors approximating a circumplex, both before and after therapy. Interpersonal Distress, Love, and Dominance changed with therapy. Structural stability, patterns of change, as well as intercultural generalizability of IIP assessments are discussed.
