Using the Personality Assessment Inventory (PAI)

The Personality Assessment Inventory (PAI: Morey, 1991) is an instrument designed for use in a wide range of clinical settings. The PAI consists of four sets of scales: four validity scales, eleven clinical scales covering major categories of pathology corresponding to current nosology, five treatment scales measuring constructs related to treatment and case management, and two interpersonal scales. This workshop is designed to provide a comprehensive overview of the use of this instrument as well as provide participants a working ability to utilize it in their practice. The workshop will describe the strategies employed in the development and validation of the PAI, drawing from data from the original samples as well as extensive subsequent research. Specifically, the presentation will provide: 1) an overview of the development of the PAI, with a focus on validation strategies as they apply to scale selection and interpretation; 2) an examination of the individual PAI scales and subscales and their interpretation in isolation and in combination with other scales; 3) a detailed discussion of profile validity issues, including supplemental indices and functions designed to address profile distortion, 4) a discussion of supplemental indicators addressing targeted clinical issues such as suicidality, dangerousness, substance abuse, and treatment decision-making, and 5) an introduction to configural scale constellations in exploring diagnostic hypotheses.
