Personal Experience Inventory™ for Adults (PEI™-A)

Personal Experience Inventory™ for Adults (PEI™-A)


This self-report inventory provides comprehensive information about substance abuse patterns in adults (age 19 or older). It can be used to identify alcohol and drug problems, make referrals, and plan treatment. And, because substance abuse rarely occurs in isolation, the PEI-A also assesses a range of psychosocial problems associated with substance abuse today.

Written at a sixth-grade reading level, the PEI-A has two parts—the Problem Severity Section (120 items) and the Psychosocial Section (150 items): 

Problem Severity Scales

  • Personal Involvement With Drugs
  • Physiological Dependence
  • Effects of Use
  • Social Benefits of Use
  • Personal Consequences of Use
  • Recreational Use
  • Transsituational Use
  • Psychological Benefits of Use
  • Preoccupation
  • Loss of Control
  • Treatment Receptiveness 

Drug Use Frequency, Duration, and Age at Onset

  • Alcohol
  • Marijuana and Hashish
  • LSD and Other Psychedelics
  • Cocaine and Crack
  • Amphetamines
  • Barbiturates
  • Tranquilizers
  • Heroin
  • Narcotics Other Than Heroin
  • Steroids and Anabolic Steroids
  • Glue and Other Inhalants

Psychosocial Scales

  • Negative Self-Image
  • Psychological Disturbance
  • Social Isolation
  • Uncontrolled
  • Rejecting Convention
  • Deviant Behavior
  • Absence of Goals
  • Spiritual Isolation
  • Peer Drug Use
  • Interpersonal Pathology
  • Estrangement in the Home

Problem Screens

  • Suicide Risk
  • Work Environment Risk
  • Past Family Pathology
  • Other Impulse-Related Problems
  • Significant Other Drug Problem
  • Sexual Abuse Perpetrator
  • Physical Abuse Perpetrator
  • Physical/Sexual Abuse Victim
  • Need for Psychiatric Referral
  • Miscellaneous (high-risk sexual behavior, gang membership, physical disability)

Validity indicators are also included.  

Respondents usually complete the test in 45 to 60 minutes. The PEI-A is then computer-scored, using WPS TEST REPORT prepaid Mail-In Answer Sheets, or CD. These options give you a complete interpretive report, which compares the client’s scores to those of two norm groups: 895 drug clinic clients and 690 nonclinical adults.    

The PEI-A detects signs of substance abuse and dependence, pinpoints the nature and style of drug use, documents onset, duration, and frequency of use, assesses factors that precipitate or maintain drug use, and identifies behavioral or emotional problems that may accompany drug use. It is invaluable for treatment planning and outcome measurement.
