Supporting individuals with intellectual disability and challenging behaviour in integrated work settings: an overview and a model for service provision.

Hagopian et al. (1999) wrote a narrative review. They sketched a multi-part service package for adults with intellectual disability plus challenging behavior who want to work in regular jobs.

The package blends vocational supports with behavior help. Think job coach plus behavior analyst on the same team.

The paper offers a blueprint, not data. No outcomes are reported. It tells agencies what pieces to bolt together, not whether those pieces work.

Earlier work already showed parts of the model can succeed. Sayers et al. (1995) ran a small case series and saw better adaptive behavior and less challenging behavior when adults got intensive community support.

Later studies tested the job side. Wehman et al. (2014) tracked 23,298 transition-age youth and found supported employment doubled competitive job rates. Iwanaga et al. (2025) repeated the win with large state data sets.

Taken together, the pieces hold up. The 1999 blueprint lines up with later evidence that jobs plus behavior help can work.

You can borrow the 1999 map today. Pair your behavior plan with a job coach, add a follow-up plan, and keep a client advocate in the loop. The later numbers say this combo raises job placement and cuts problem behavior at the same time.
