Providing services in the United Kingdom to people with an intellectual disability who present behaviour which challenges: a review of the literature.
UK locked units for challenging behaviour cost much and achieve little, while newer community programmes safely cut medication.
01Research in Context
What this study did
McKenzie (2011) read every UK paper about services for people with intellectual disability who show challenging behaviour. The review looked at three models: campus-style units, outreach teams, and ordinary community supports.
No new data were collected; the author stitched together earlier reports to see which approach works best.
What they found
Specialist campus units rely on locked doors, seclusion and high-dose antipsychotics, but behaviour gains are small. Outreach teams exist, yet no solid proof shows they cut challenging behaviour. Community services are the least studied option.
In short, the UK spends millions on restrictive placements without strong evidence of benefit.
How this fits with other research
Karen’s picture matches the 2007 survey by N et al. of 38 assessment and treatment units: beds fill up, people stay for years, and discharge plans are missing. The review simply updates that story.
Spanoudis et al. (2011) audited UK prescribing the same year and found most antipsychotic use was ‘guideline-consistent.’ McKenzie (2011) counters that even ‘appropriate’ meds in these units rarely free clients from restraint. The views seem opposite until you see C counted paperwork while Karen counted real-life outcomes.
Agiovlasitis et al. (2025) later showed brief staff training in the community can safely halve antipsychotic doses. This successor study fills the evidence gap Karen flagged and points away from locked provision.
Why it matters
If you write behaviour-support plans, question any referral to a ‘specialist’ unit that uses seclusion or off-label medication. Ask for data: how many people left in the last year, and where did they go? Push instead for community teams with clear discharge dates and medication-taper protocols like SPECTROM. Your advocacy can shift funding toward settings that already show safer, drug-light outcomes.

03Original abstract
There is ongoing debate about the best model of service provision for people with an intellectual disability who present severe behavioural challenges. The present paper reviewed research which evaluated a range of UK service provision in terms of impact on challenging behaviour and other quality of life indices. A literature search was carried out for English language papers from 1990 to 2010 using a range of databases. Secondary searches were carried out from references of relevant papers. Very few evaluations were found. The available research indicates that, on the whole, specialist congregate services for individuals with challenging behaviour appear to use more restrictive approaches which have limited effect on reducing challenging behaviour. The evidence for peripatetic teams is somewhat unclear. The two studies reviewed showed positive outcomes, but both had limitations that made it difficult to generalize the results. A similar limitation was found with the sole evaluation of a community based service. It is unlikely that one model of service provision will meet the needs of all individuals, however, more robust evaluations are required of existing service models to allow commissioners, service users, their families and carers to make fully informed choices about effective services for those who challenge.
