Service Delivery

Beyond specialist programmes: a study of the needs of offenders with intellectual disability requiring psychiatric attention.

Glaser et al. (2004) · Journal of intellectual disability research : JIDR 2004
★ The Verdict

Offenders with ID and mental illness fall through the cracks between services—one key worker who bridges disability and psychiatry teams can stop the fall.

✓ Read this if BCBAs who serve adults with ID in forensic or community mental-health settings.
✗ Skip if Clinicians who work only with children or with clients who have no justice involvement.

01Research in Context

01

What this study did

A UK forensic clinic tracked every new client with intellectual disability who also needed mental-health care. Staff listed each person's diagnoses, living situation, and service gaps. They simply described what they saw; no treatment was tested.

02

What they found

The caseload was sicker and needier than expected. Most clients had several psychiatric labels on top of ID. Regular mental-health teams and ID teams had already turned them away. The clinic proposed one key worker to steer each client through both systems.

03

How this fits with other research

Matson et al. (2009) scanned all Finnish offenders with ID and found the same triple-diagnosis picture—ID plus mental illness plus substance abuse—on a country-wide scale. The numbers back up the clinic's small-sample story.

Thomas et al. (2004) surveyed high-security hospital patients with ID in the same year. One in three could leave today if community services could handle their mix of needs. Together the papers paint a UK system where secure beds are clogged and community doors are closed.

Boudreau et al. (2015) followed prisoners with ID just before release. Drug use and hepatitis C were rampant, yet no one coordinated disability, health, and justice plans. The clinic's key-worker model could plug that transition gap.

Why it matters

If you assess or treat adults with dual diagnosis, expect referrals that no one else wants. Build one coordinated plan that crosses mental health, ID, and forensic lines. Share the plan with every agency before discharge; otherwise clients bounce back or land in jail.

03Original abstract

BACKGROUND: Despite the increased prevalence of psychiatric disorder amongst offenders with an intellectual disability (ID), there is very little known about the characteristics and needs of those with dual disability. METHOD: A study of admissions to a new community forensic dual disability clinic during the first 10 months of its operation. RESULTS: Typically, the offenders are male, are older than other offenders, exhibit long-standing and continuing serious behavioural disturbance (independent of their psychiatric diagnosis or level of involvement with the criminal justice system) and require supported or custodial accommodation, despite only mild or borderline levels of ID. Although only one-third have a diagnosable major nonparaphilic psychiatric disorder, three-quarters have had prior or current contact with psychiatric services and two-thirds suffer chronic medical illness. CONCLUSIONS: These offenders suffer psychosocial disadvantages far more extensive than those implied by the "psychiatric" or "disability" label. The multiple services provided to this group have been ad hoc, poorly co-ordinated and sometimes dangerously inappropriate. A service provision model is required which must be integrative and consistent. We suggest the use of multiskilled key workers, who maintain close contact with individual clients. Their role will be to implement management plans from the various specialist agencies who become involved with this group and provide long-term follow-up of their recommendations.
