Brief report: impact of applied behaviour analysis (ABA) on carer burden and community participation in challenging behaviour: results from a randomised controlled trial.
For adults with ID and challenging behavior, ABA in this trial did not reduce carer burden or increase community participation.
01Research in Context
What this study did
Researchers ran a randomized controlled trial with adults who have intellectual disability and challenging behavior.
Half received a standard ABA program. The other half kept their usual services.
After six and 24 months the team checked carer stress and how often families joined community activities.
What they found
ABA did not lower carer burden more than usual care.
Community outings also stayed the same in both groups.
In short, the program showed no extra benefit for these adult-focused goals.
How this fits with other research
Rodgers et al. (2021) and Van Gaasbeek et al. (2026) report that early intensive ABA helps preschoolers learn skills.
Those reviews did not include adults, so the null finding here does not clash with child data.
Strydom et al. (2020) tested Positive Behaviour Support in a similar adult group and also saw no gain, backing the idea that broad packages may not move carer stress in this population.
Why it matters
If you serve adults with ID, do not assume a generic ABA plan will ease family stress or boost outings. Track those targets directly, and add carer coaching or respite if those are the real needs.

03Original abstract
BACKGROUND: Applied behaviour analysis (ABA) reduces challenging behaviour in people with intellectual disability. There is interest, however, in whether such interventions reduce carer burden and increase community participation in this group. METHODS: A 6-month randomised controlled trial was followed by a longer-term naturalistic follow-up of participants. We studied the impact of the challenging behaviour on the carers and on the daily activities of the participants measured by the Carer Uplift and Burden Scale and Guernsey Community Participation and Leisure Assessment respectively. RESULTS: Both community participation and carer burden improved at 6 and 24 months. Burden showed significant reduction in family carers compared with paid carers. There was no significant intervention effect on the variables under consideration. CONCLUSIONS: ABA appears to be no more effective than standard care in improving social outcomes in people with intellectual disabilities and challenging behaviour but this requires further examination in a larger trial.
