Rehabilitation for adults with an intellectual disability and mental health and behavioural complexities: A scoping review

Background

There has been significant focus in the past decade on reducing admissions to assessment and treatment units for people with intellectual disabilities experiencing mental health or behavioural concerns. This has included the development of intensive support functions of National Health Service Learning Disability services to bolster community support and treatment for people at risk of admission. However, in recent years, there has been increased consideration of service development to include rehabilitation functions which would aim to proactively provide medium-term additional input to individuals with a complexity of need. This input would aim to improve future trajectories and support the individuals to remain living a good life in their own community. This review focuses on community and in-patient approaches to meeting a complexity of need.

Method

A scoping review was carried out according to established best practice guidelines. Papers returned from the search were screened by the following inclusion criteria (a) Models or Outcomes of Rehabilitation; (b) Intellectual Disability Population; (c) Sample being 18 or above and (d) longer than short-term stay/treatment, defined as 6 months or longer; and (e) Mental health and/or behaviour complexities. The search was conducted in electronic databases CINAHL, PsycInfo, Medline, Embase and Social Policy & Practice. Here, 3790 articles were initially identified and 27 were ultimately included in the review.

Findings

There are few studies evaluating rehabilitation for people with intellectual disabilities and mental health or behavioural concerns. There was some evidence that accessing assessment and treatment inpatient provision resulted in clinical improvements. Some studies demonstrated initial evidence that longer term rehabilitation was beneficial as a step-down from inpatient care. Some key principles were identified in terms of rehabilitation approaches: the need for person-centred creative approaches, suitable staff training, focus on building skills, and a focus on increasing quality of life.

Conclusion

There are some indicators of what good rehabilitation services might comprise for people with an intellectual disability, who have rehabilitation needs. However, far more research and guidance are required in this area. In particular, it is unclear whether rehabilitation is best provided within an inpatient or community model, and further detail is required about optimal components of such rehabilitation.
