Administer the Gold-Standard Inventory of Adult Personality - 344 Items in Less than One Hour


The PAI assesses psychopathological syndromes and provides information relevant for clinical diagnosis, treatment planning, and screening for psychopathology. Administration time is up to 40 minutes shorter than that for similar instruments.


Features and benefits

  • Unique, efficient scale structure. All 22 scales are nonoverlapping, promoting high discriminant validity. Scale development was content-driven.
  • Fast, cost-effective administration. Clients generally complete the 344 items in less than an hour. Scales and subscales can be hand-scored in only 15-20 minutes.
  • Can be used with low-reading level populations. The PAI requires only a fourth-grade reading level; an audio administration CD is also available.
  • No scoring keys needed. A two-part carbonless Answer Sheet provides scores for all 344 items.
  • Provides strategies for interpretation. The Professional Manual includes an expanded discussion of administration considerations and a variety of strategies for the interpretation of clinical data.
  • Portable materials. The PAI Administration Folio provides a hard surface for both the Item Booklet and Answer Sheet for situations in which no desk or tabletop is available.
  • Available 24/7. Administration and scoring are available 24/7 on PARiConnect, our online assessment platform. 


Available in Spanish

  • PAI Spanish: Revised Translation. Uses English-language norms and features clearer, more inclusive language while maintaining semantic fidelity to the PAI.
  • Personality Assessment Inventory: European Spanish With Norms. The PAI materials, including the manual, have been translated into European Spanish and designed especially for Spanish-speaking clinicians and their clients. Normative data were collected primarily in Spain, with additional data collected in some Latin American countries. Certain test items and stimuli in this translation vary from the English version because of cultural and linguistic differences between the countries and their language.
