Derived from the Personality Assessment Inventory (PAI), the PAS is designed for use as a triage instrument in most health care and mental health settings, as well as in corporate EAPs and college health services. The 22-item test may be an important part of initial client evaluation by health care and mental health professionals:
- To determine the need for a follow-up with a full evaluation of psychopathology.
- To focus the initial client interview on specific problem areas.
- To target certain clinical areas for follow-up testing.
This self-administered objective questionnaire was developed with reference to its parent instrument, the PAI. The 22 PAS items are those items from the PAI that have been identified by extensive item analysis as the most sensitive to the broad range of contemporary clinical problems measured by the PAI. The items are organised hierarchically into 10 different "Elements" representing 10 distinct clinical problem domains:
- Negative Affect (NA)
- Hostile Control (HC)
- Acting Out (AO)
- Suicidal Thinking (ST)
- Health Problems (HP)
- Alienation (AN)
- Psychotic Features (PF)
- Alcohol Problem (AP)
- Social Withdrawal (SW)
- Anger Control (AC)
The 10 individual Element raw scores are summed to determine the PAS Total score, which assesses both the potential for emotional and/or behavioural problems of clinical significance and the need for follow-up evaluation with the PAI or another full inventory of adult personality.
Individual Element scores and the PAS Total score are transformed into probability (P) scores, reflecting the likelihood that the respondent would obtain a problematic profile if they completed the full 344-item PAI. These scores were derived from analyses of 2,631 individuals in both clinical and community settings (ages 18 years and older). Normative data are presented for a national community sample of 1,000 adults matched by age, race, and gender to census projections for 1995, as well as for 1,246 clinical participants and 1,051 college students.
PAS materials include the Professional Manual and the 2-part carbonless Form HS Response Form. The bottom part of the Response Form provides scoring and profiling grids with interpretation for PAS Element and Total P scores. The Professional Manual provides information on development, item selection, reliability and validity, internal consistency, empirical structure, administration and scoring, and interpretation of the screening test.
