The essential features of personality disorder in DSM-5: the relationship between criteria A and B.

The essential features of the general criteria for personality disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), are based on impairments in self and interpersonal functioning (criterion A) and pathological personality traits (criterion B). The current study investigated the relationship between criteria A and B in a German psychiatric sample (N = 149). Criterion A was measured by the General Assessment of Personality Disorder (GAPD); criterion B, by the Dimensional Assessment of Personality Pathology (DAPP) and the Revised NEO Personality Inventory (NEO-PI-R).

Differentiating normal and disordered personality using the General Assessment of Personality Disorder (GAPD).

Criteria to differentiate personality disorder from extremes of normal personality variations are important given growing interest in dimensional classification because an extreme level of a personality dimension does not necessarily indicate disorder. The DSM-5 proposed classification of personality disorder offers a definition of general personality disorder based on chronic interpersonal and self/identity pathology. The ability of this approach to differentiate personality disorder from other mental disorders was evaluated using a self-report questionnaire, the General Assessment of Personality Disorder (GAPD).

The General Assessment of Personality Disorder (GAPD): factor structure, incremental validity of self-pathology, and relations to DSM-IV personality disorders.

Recent developments in the classification of personality disorder, especially moves toward more dimensional systems, create the need to assess general personality disorder apart from individual differences in personality pathology. The General Assessment of Personality Disorder (GAPD) is a self-report questionnaire designed to evaluate general personality disorder. The measure evaluates 2 major components of disordered personality: self or identity problems and interpersonal dysfunction.
