Background
People with intellectual disabilities have a high risk of developing mental ill‐health. Treatment is often neglected and diagnosis is misattributed to a person's disability. Standard psychosocial interventions can improve a person's well‐being. This review aimed to understand what interventions are being delivered, any benefits, and future recommendations.
Methods
Preferred Reporting Items for Systematic reviews and Meta‐Analyses (PRISMA) guidelines were followed, and the review registered with PROSPERO—CRD42020160254. Databases searched included: MEDLINE, Embase, and PsycINFO. A framework synthesis approach was used to present the findings.
Results
There are limited psychosocial interventions offered for this population. When groups are delivered having a creative element, multiple activities over a short period of time, with breaks and group rules outcomes can be improved.
Conclusions
Adaptations and reasonable adjustments should be used specifically to a person's ability. A mixed‐method design allows people to share their experiences alongside quantitative data that provides clinical information.
