The Inventory of Interpersonal Problems (IIP-64) as a Screening Measure for Avoidant Personality Disorder
European Journal of Psychological Assessment, 01/26/09

Leising D et al. - Interview-based diagnoses of AVPD were predicted with good diagnostic accuracy by a single scale (socially inhibited) of the IIP-64, whereas the presence of any kind of PD was more accurately predicted by the IIP-64 total score. The IIP-64 not only assesses general personality pathology, but may also be used in screening for specific kinds of personality pathology, which have greater clinical relevance.
