The Relationship Between Personality Inventory for DSM (PID-5) Domains and Disruptive Behavior Disorders.

Abstract

Introduction: Previous research has demonstrated a strong relationship between personality and psychopathology. However, the relationship between the traits listed in the Alternative Model for Personality Disorders (AMPD) and Disruptive Behavior Disorders (DBD) in adolescents has not been examined in detail. This study aimed to examine the relationship between the Personality Inventory for DSM-5 (PID-5) domains and DBD symptoms in an adolescent inpatient sample.

Methods: A total of 127 adolescents (71% female) aged 12-17 years (M = 15.24, SD = 1.33) were recruited from an inpatient psychiatric hospital. These participants exhibited a wide range of psychiatric disorders unresponsive to prior interventions. They completed the PID-5-Short Form, the Child Behavior Checklist (CBCL), and the Diagnostic Interview Schedule for Children - Computerized Version (DISC-IV).

Results: The antagonism, disinhibition, and psychoticism domains showed significant correlations with DBD scores. Hierarchical regression models predicting total DISC-IV and CBCL scores indicated that the addition of the PID-5 Antagonism and Disinhibition scales did not provide incremental predictive validity over total DBD symptoms.

Conclusion: DBD symptoms are related to psychoticism, antagonism, and disinhibition. However, total Antagonism and Disinhibition scores did not contribute additional predictive power for overall psychopathology beyond DBD scores. These findings highlight questions about the discriminant validity of the PID-5 and suggest further research into the construct validity of these domains.
