What is the PAI?

The Personality Assessment Inventory (PAI) provides information relevant for clinical diagnosis, treatment planning and screening for psychopathology. The PAI covers constructs most relevant to a broad-based assessment of mental disorders. It is comprised of 344 items and requires 50-60 minutes to administer. Each item is rated on a 4-point true/false scale. The PAI consists of 22 non-overlapping full scales including 4 validity scales, 11 clinical scales, 5 treatment scales, and 2 interpersonal scales. To facilitate interpretation and cover the full range of complex clinical constructs, 10 full scales contain conceptually derived subscales.

Why Should I Use the PAI?

RELIABLE AND VALID. The PAI is a thoroughly validated instrument with data from three (3) samples: (a) a census-matched normative sample of 1000 community-dwelling adults (matched on the basis of gender, race and age); (b) a sample of 1265 patients from 69 clinical sites; (c) a college sample of 1051 students. Reliability studies show that PAI scales have a high degree of internal consistency. Validity studies demonstrate the convergent and discriminant validity of PAI scales with more than 50 other measures of psychopathology.

UNIQUE SCALE STRUCTURE. All 22 scales of the PAI are nonoverlapping, promoting high discriminant validity. Scale development was content-driven.

CONVENIENT. Administration of the 344 items that comprise the hard copy assessment takes 50-60 minutes. Scoring is quick and easy and can be completed in only 15-20 minutes using its two-part carbonless Answer Sheet.

INTERPRETIVE guidance. The PAI professional manual offers an expanded section of information, resources, and strategies devoted to the interpretation of clinical data and discussion of administration considerations.
