This meta-analysis evaluated the validity of the Personality Inventory for DSM-5 (PID-5) in measuring ICD-11 trait model constructs across 12,840 individuals, including psychiatric patients and nonpatients. The findings indicated a strong five-factor structure with good model fit indices, supporting the PID ICD scale's internal and external validity. The mean scores for clinical samples were significantly higher than nonclinical samples, with effect sizes ranging from 0.68 to 1.37.
Key findings
- The PID ICD scale demonstrated a five-factor structure with good model fit indices (RMSEA = .06, CFI = .97).
- Alpha coefficients for all factors ranged from .86 to .93, indicating strong internal consistency.
- Mean scores for clinical samples were significantly higher than nonclinical samples, with effect sizes between 0.68 and 1.37.
- Area Under the Curve values for the PID ICD scale ranged from .65 to .83, indicating good diagnostic performance.
Why it matters
Understanding the validity of the PID-5 in relation to ICD-11 traits can enhance diagnostic accuracy and treatment planning in clinical settings, particularly for personality disorders.
