The Adolescent and Adult Psychoeducational Profile: assessment of adolescents and adults with severe developmental handicaps.

Mesibov et al. (1989) · Journal of autism and developmental disorders 1989
★ The Verdict

The AAPEP is a quick, trusted way to spot work and life-skill needs in teens and adults with autism plus severe ID.

✓ Read this if BCBAs who draft transition or vocational plans for adolescents and adults with dual diagnosis.
✗ Skip if Clinicians who only serve young children or clients without intellectual disability.

01Research in Context

01

What this study did

The team built a new test called the AAPEP. It looks at work, social, and daily-living skills in teens and adults with autism and severe intellectual disability.

Two raters watched the same clients and scored them. Later, experts compared the AAPEP ideas to the old IEP goals without knowing which was which.

02

What they found

Both raters gave nearly the same scores. That means the test is reliable.

The blind experts said the AAPEP goals were more useful than the current IEP goals. Parents also liked the new plan better.

03

How this fits with other research

Szempruch et al. (1993) followed the same clients five years later. Early PEP scores predicted later AAPEP scores. This backs up the AAPEP as a crystal ball for adult skills.

Wigham et al. (2021) hunted for trauma tools for autistic adults with mild ID. They did not rate the AAPEP, but they show the field still needs solid measures for this group.

Mantzalas et al. (2024) made a burnout scale for autistic adults. Their work keeps the theme alive: we need adult tests, not just child ones.

04

Why it matters

If you write transition plans for teens or adults with autism and ID, the AAPEP gives you clear, reliable goals that teams actually want to use. Swap it in for part of your next assessment and watch the IEP meeting get shorter and sharper.

03Original abstract

The purpose of this study was to determine the reliability and validity of the Adolescent and Adult Psychoeducational Profile (AAPEP), an assessment instrument designed for adolescents and adults with severe developmental handicaps. Subjects were 60 adolescents and adults, 30 with autism and 30 with mental retardation but without autism. The groups were matched on age and IQ. Results suggested high interrater reliability on all function areas of the AAPEP (Vocational Skills, Independent Functioning, Leisure Skills, Vocational Behavior, Functional Communication, Interpersonal Behavior) and on all three scales (Direct Observation, Home, School/Work). Validity measures suggested that the recommendations generated from the AAPEP were viewed by blind experts as more helpful than those already generated for the individual clients and contained in their Individual Education Programs (IEPs) or Individual Habilitation Plans (IHPs). Informal measures indicated that parents and/or group home staff also found AAPEP recommendations helpful. Finally, reliability and validity measures were also encouraging for moderately and severely handicapped adolescents and adults without autism. The AAPEP appears to be an effective new instrument for those working with older handicapped clients.
