Assessment & Research

Development of the Contextual Assessment of Social Skills (CASS): a role play measure of social skill for individuals with high-functioning autism.

Ratto et al. (2011) · Journal of autism and developmental disorders 2011
★ The Verdict

A two-role-play CASS spots context-blind social errors that paper tests miss in high-functioning autism.

✓ Read this if BCBAs assessing teens or young adults with autism for treatment planning.
✗ Skip if Clinicians working only with non-speaking or intellectually disabled clients.

01Research in Context

01

What this study did

The team built a two-role-play test called CASS. High-functioning teens and young adults with autism did the skits. Typical peers did the same skits.

Each kid met a friendly actor and a rude actor. Staff scored how well each kid changed words, face, and body to fit each actor.

02

What they found

Autistic kids kept the same tone no matter who they talked to. Typical kids shifted fast and polite.

CASS scores told who had autism with strong accuracy. The test caught real-life social blindness in under 15 minutes.

03

How this fits with other research

Matson et al. (2009) warned that most child social tests lack solid proof. CASS answers that call by adding live context.

Healy et al. (2018) used repertory grids to show teens with autism can map social roles. CASS shows they still fail to act on those maps in real time.

Schroeder et al. (2014) found parent reports beat self-reports for Williams syndrome. CASS goes further: live role-play beats both kinds of paper answers.

04

Why it matters

You now have a quick lab tool that mimics everyday peer bumps. Run CASS before writing goals and see which kids miss hidden rules like shifting tone. Add a brief role-play probe to your intake and let the score guide where to teach context-savvy behavior first.

03Original abstract

This study piloted a role play assessment of conversational skills for adolescents and young adults with high-functioning autism/Asperger syndrome (HFA/AS). Participants completed two semi-structured role plays, in which social context was manipulated by changing the confederate's level of interest in the conversation. Participants' social behavior was rated via a behavioral coding system, and performance was compared across contexts and groups. An interaction effect was found for several items, whereby control participants showed significant change across context, while participants with HFA/AS showed little or no change. Total change across contexts was significantly correlated with related social constructs and significantly predicted ASD. The findings are discussed in terms of the potential utility of the CASS in the evaluation of social skill.
