Three validation studies of the personality assessment inventory short form.

Objective: We examined the psychometric properties of the Personality Assessment Inventory-Short Form (PAI-SF).

Method: Study 1 compared single-session short and full form PAI profiles of 200 outpatients, Study 2 examined PAI forms of 107 nonclinical adults across two administrations, and Study 3 compared correlations between full and short form scales and extratest variables.

Results: Study 1 correlations between short and full form scales ranged from 0.85 to 0.95 (Mdn = 0.91), with lower correlations, ranging from 0.59 to 0.86 for clinical scales (Mdn = 0.82), in Study 2. In Study 3 only 4 of 34 correlations differed significantly between extratest variables and the PAI versus the PAI-SF.

Conclusions: These results indicate favorable psychometric properties of the PAI-SF.
