Social problem-solving and mild intellectual disabilities: relations with externalizing behavior and therapeutic context.

van Nieuwenhuijzen et al. (2009) · American journal on intellectual and developmental disabilities 2009
★ The Verdict

Kids with mild ID and severe externalizing behavior know assertive solutions yet still act aggressively—interventions must bridge this knowing-doing gap.

✓ Read this if BCBAs working with school-age children with mild ID in residential or day-treatment settings.
✗ Skip if Clinicians serving only typically developing clients or adults with severe ID.

01Research in Context

01

What this study did

The team gave a survey to children with mild intellectual disability.

They compared kids living in residential care with kids living at home.

The survey asked how the children solve social problems and how much they act out.

02

What they found

Kids in residential care showed more hitting, yelling, and rule-breaking.

These kids could name calm, assertive solutions, but still picked aggressive ones.

Knowing the right answer did not stop the bad behavior.

03

How this fits with other research

Davison et al. (1991) already showed that teaching both assertiveness and problem-solving helps adults with mild ID. Their work proves the skills can be taught.

Dickson et al. (2005) first looked like they disagreed; they found more anti-social behavior in teens with ID. But the extra behavior vanished when they accounted for poverty and mental-health issues. The clash disappears once life conditions are held equal.

Marsack et al. (2017) extended the story to adolescents. They found that simply enrolling in social-skills class predicted fewer risky acts, hinting that practice, not just knowledge, matters.

04

Why it matters

Your client may already tell you the “nice way” to handle teasing, yet still throw a chair. Use role-play and in-the-moment coaching to bridge the knowing-doing gap. Add parent stress screens from Busch et al. (2010) and watch for hidden depression per Myrbakk et al. (2008) to round out your treatment plan.

03Original abstract

Relations among externalizing behavior, therapeutic context (community care vs. residential care), and social problem-solving by children with mild intellectual disabilities or borderline intelligence were examined. Participants were 186 children (12 to 14 years of age) who responded to a video-based social problem-solving task. Of these, 130 received residential care and the majority suffered from severe externalizing behavior problems. The results indicated that externalizing behavior was related to encoding, generation of aggressive responses, and negative evaluation of assertive responses. Therapeutic context was related to encoding, positive evaluation of assertive responses, and negative evaluation of aggressive responses. Results indicate a discrepancy between appropriate problem-solving skills and behavior in daily life. Implications for interventions are discussed.
