The Personality Assessment Inventory (PAI; Morey, 1991) is a widely used 344-item self-report measure of personality and psychopathology. Normative data for the PAI has been established in community, college, and clinical samples, as well as in bariatric and chronic pain populations (Corsica et al., 2010; Karlin et al., 2005; Morey, 1996). To date, normative data for the PAI has not been established in a physical rehabilitation population. This study examines the clinical utility and psychometric properties of the PAI in a sample of persons involved in a tertiary level insurance-funded physical rehabilitation program (n = 466; 53.6% women, Mage=43.3, SD=12.2). Results of internal consistency analyses of PAI full and subscales demonstrated good reliability and were relatively consistent with reliability reported for original development sample. Exploratory factor analyses were conducted to investigate the underlying structure of the PAI with this population. Normative data and scale elevations were examined. Results support the use of the PAI in the assessment of insurance-based rehabilitation populations. The normative data and scale elevations found in this study will facilitate PAI interpretation and inform treatment recommendations for individuals undergoing a physical rehabilitation treatment program.
