Product Description

The APS measures three broad disorder-problem domains: Clinical Disorders (20 scales), Personality Disorders (5 scales) and Psychosocial Problem Content areas (11 scales). The Response Style Indicator scales (4 scales) includes indexes of response consistency, response veracity and unusual endorsement propensities.

Respondents complete the 346 items in the APS Test Booklet. APS items are written at a year 8 reading level. The APS employs a unique multiple response format designed to conform to the nature of the specific DSM-IV symptom criteria. APS scores represent the severity of disorder-specific symptomatology evaluated across different time periods. This close match between APS item content and DSM-IV criteria facilitates clinical utility and ease of interpretation. To quantify the primary dimensions of psychopathology captured by the APS, three broad-based Factor Score scales are calculated from the Clinical and Personality Disorder scales: Internalizing Disorder, Externalizing Disorder, and Personality Disorder.

After paper-and-pencil administration, the user enters the adolescent's responses to the 346 items using the APS Scoring Program and selects the appropriate normative comparison group. The software calculates scores for all scales and automatically generates a Clinical Score Report with the following information:

  • Use of the APS Clinical Score Report.
  • Summary of APS Scale Elevations.
  • APS Score Summary Table.
  • Profile of APS Clinical Scores (based on the selected normative comparison group).
  • Critical Items Summary Form.
  • Item Response Summary Table.

Requirements: Windows® 2000/XP/Vista; CD-ROM drive for installation

NOTE: The APS must be scored using the APS Scoring Program. The APS is available on CD-ROM, which can generate unlimited reports. The CD-ROM does not require the use of Key Disks. A 115-item short form (APS-SF) is also available.
