| Abstract: | Research focusing on the Personality Assessment Inventory (PAI) has increased substantially over the past decade. However, there has been relatively little focus on the PAI short-form (PAISF). The current study evaluated the psychometric characteristics of the PAI-SF clinical scales using participants admitted to a large northeastern hospital under forensic (N?=?178) and civil (N?=?320) statutes. Results indicate that the internal consistency of the PAI-SF clinical scales is adequate for both the Forensic (range of alphas: 0.74 to 0.88) and Civil (0.79 to 0.91) samples, and assumptions of item-scale convergence and divergence were generally met with some exceptions. Finally, the PAI-SF exhibited strong agreement with the full-form PAI scores overall, and at the upper extreme (T?≥?70) of the distributions for both samples. The results are discussed in terms of how they extend prior research on the PAI-SF. |
