Do PID-5 Trait Scores Predict Symptom Disorders? A Meta-analytic Review.

Area of Science:

• Psychology
• Psychiatry
• Clinical Psychology

Background:

• The Personality Inventory for DSM-5 (PID-5) is a key tool for assessing personality dysfunction.
• Research has explored links between PID-5 domains and personality pathology, as well as symptom disorders.
• This study synthesizes existing research on PID-5 associations with symptom disorders.

Approach:

• A meta-analytic approach was used to synthesize findings from 26 publications.
• The analysis included 260 effect sizes across the five PID-5 trait domains.
• Statistical significance was established for all reported effect sizes (p < .00001).

Key Points:

• PID-5 domain scores showed significant correlations with symptom disorders.
• Effect sizes ranged from 0.20 for Antagonism to 0.35 for Negative Affect.
• Observed relationships were largely consistent with theoretical expectations, with some novel findings.

Conclusions:

• The PID-5 reliably predicts symptom disorders, not just personality dysfunction.
• These findings enhance the clinical utility and heuristic value of the PID-5.
• The dimensional assessment of personality traits offers valuable insights into psychopathology.
