Objectives
The Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) Section III includes an alternative model for diagnosing six personality disorders (PDs) with evaluating functional impairment (Criterion A) as well as 25 maladaptive personality facets (Criterion B). The Personality Inventory for DSM-5 1 was developed by the DSM-5 Personality and Personality Disorders workgroup to assess Criterion B of this new model. The aim of the current study was to examine the prediction DSM-5 Section III PD trait combinations using the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF 2); a frequently used measure of personality and psychopathology with a strong relation with contemporary models of personality.
Methods
The sample consisted of 536 (209 men, 327 women) individuals who were recruited through the general population in Iran.
Results
Hierarchical linear regression analyses indicated that the DSM-5 Section III PD trait combinations could be predicted using the MMPI-2-RF in an Iranian population, with several divergences.
Conclusions
As expected, the majority of hypothesized scales had the largest effect sizes in the prediction of Criterion B of DSM-5 Section III PDs. This finding has implications for assessing the alternative model for personality disorders (AMPD) using the MMPI-2-RF in this population.
