DO PID-5 TRAIT SCORES PREDICT SYMPTOM DISORDERS? A META-ANALYTIC REVIEW

Abstract

The Personality Inventory for DSM-5 (PID-5) has become influential in the dimensional assessment of personality dysfunction. Though most studies have examined links between PID-5 trait domains and personality pathology, a number of investigations have assessed relationships between PID-5 scores and symptom disorders (e.g., depression, anxiety). We employed meta-analytic techniques to synthesize findings in this area, identifying 26 publications assessing associations between PID-5 scores and symptom disorders (N of effect sizes across the five trait domains = 260). PID-5 domain score effect sizes (rs) ranged from 0.20 for Antagonism to 0.35 for Negative Affect (all ps < .00001). Relationships between PID-5 scores and specific forms of psychopathology were generally consistent with expectations, with some unanticipated relationships as well. Findings confirm that the pathological personality traits assessed by the PID-5 predict symptom disorders as well as personality dysfunction, extending the heuristic value and clinical utility of the measure.
