Further studies of the clinical utility of the “Alternative DSM-5 Personality Disorder Model” are warranted, especially in clinical samples. Overall, the 25 PID-5 facets appeared useful in describing the six retained personality disorders in DSM-5 (Antisocial, Avoidant, Borderline, Narcissistic, Obsessive Compulsive, & Schizotypal), and the eight personality disorders which were eliminated in current or past editions (Dependent, Depressive, Histrionic, Passive-Aggressive, Paranoid, Sadistic, Schizoid, and Self-defeating). The PID-5 facets appeared to describe the previously defined and established 14 CATI personality disorder scales with exceptionally high R and R2adj values when tested against the CATI. Results indicated that the 25 PID-5 facets appeared to have good-to-excellent internal reliability and strong positive correlations with all the CATI-25 facets. The new scales are named the CATI-25 facet scales, and are designed as an independent alternative to the PID-5 25 facet scales. Additionally, a new set of 25 personality facet scales, adapted from the Coolidge Axis II Inventory, which correspond to the 25 DSM-5 personality facets as defined in Section III, were developed to provide an independent instrument to test the effectiveness of the 25 facet dimensional model. These two established instruments (CATI and PBQ) will be used to determine if the alternative DSM-5 dimensional model is as effective at diagnosing personality disorders, as were the previously defined 14 categorical personality disorders. This instrument is published as a supplement to the DSM-5 and can be retrieved from their website. The American Psychiatric Association has provided an assessment instrument for measuring the 25 personality facets named the “Personality Inventory for DSM-5“(PID-5)”. The present study offers the psychological community empirical evidence on the efficacy of the alternative DSM-5 model, by comparing and contrasting its ability to diagnose the previously defined 14 DSM (all versions) personality disorders using established personality disorder scales, specifically the Coolidge Axis II Inventory (CATI Coolidge, 2000), and the Personality Belief Questionnaire (PBQ Beck et al., 2001). ![]() With the publication of Diagnostic and Statistical Manual of Mental Disorders (DSM-5 American Psychiatric Association, 2013), a new approach to diagnosing personality disorders was offered in Section III, entitled “Alternative DSM-5 Model for Personality Disorders”. Our evaluation generally supported the utility for clinical purposes of the Alternative Model for Personality Disorders in Section III of the DSM-5, although it also identified some areas for refinement. ![]() Implications for ease of use, communication, and psychotherapy are discussed. Using the LPFS and PID-5, we were able to characterize the 6 cases in a meaningful and useful manner with regard to understanding and treatment of the individual patient and to match the cases with 6 relevant personality disorder types. We also considered 6 specific personality disor- der types that could be derived from the profiles as defined in the DSM-5 Section III criteria. The personality profiles of six characteristic patients were inspected (involving a comparison of presenting problems, history, and diagnoses) and used to formulate treatment considerations. We administered the LPFS and the PID-5 to psychi- atric outpatients diagnosed with personality disorders and other nonpsychotic disorders. The goal of this study was to evaluate the clinical utility of this alternative model of personality disorders. ![]() ![]() A number of studies have supported the psychometric qualities of the LPFS and the PID-5, but the utility of these instruments in clinical assessment and treatment has not been extensively evaluated. These novel instruments assess level of personality impairment and pathological traits. In Section III, Emerging Measures and Models, DSM-5 presents an Alternative Model of Personality Disorders, which is an empirically based model of personality pathology measured with the Level of Personality Functioning Scale (LPFS) and the Personality Inventory for DSM-5 (PID-5).
