People with intellectual disabilities (ID) often experience difficulties managing their affairs. This study reviewed self-management interventions for people with mild to moderate ID, studying interventions' effectiveness and applied behavioural change techniques (BCTs). Methods: A systematic literature search was conducted in PubMed, PsychINFO, Web of Science, Embase, Emcare, Cochrane, and ProQuest. Data were extracted on study, intervention, and participant characteristics, and results. Results: Of the 681 studies retrieved, 36 met the inclusion criteria. Most studies used case study designs and small samples. There were eight randomised controlled trials and one non-randomised study. Studies were mostly of moderate quality (Mixed Methods Appraisal Tool). Twenty-two interventions targeted a singular practical skill for a specific context. In allinterventions, the provider applied several BCTs; in 13 studies participants were also trained to apply BCTs themselves. In all studies, improvements in self-management were reported, which mostly maintained over time (n = 20). If measured, generalisation to other settings was also found. Conclusions: Future studies should aim for a higher methodological quality and couldconsider targeting more generic self-management and a wider application of BCTs by people with ID themselves. Practice implications: The findings suggest that training can promote self-management in people with ID.
