Mental health: knowledge, attitudes and training of professionals on dual diagnosis of intellectual disability and psychiatric disorder.

Falcomata et al. (2012) looked at every paper they could find on staff who treat people with both intellectual disability and mental illness. They read studies from doctors, nurses, and therapists. The goal was to see how much these workers knew and how they felt about clients with dual diagnosis.

The review says most helpers lack basic facts. Many hold negative views, seeing clients as too hard or even dangerous. Few had any formal class on dual diagnosis after college. The authors say better training is essential.

van der Geest et al. (2002) already proved a fix works. They used a mentoring plan that lifted team use of both behavior plans and medicine. Gains lasted six months. This turns the 2012 call into action: train, don’t just complain.

Black et al. (2019) widen the gap. They asked teachers about kids with ASD, Down, and Williams syndromes. Staff spotted big traits but missed hidden needs and gave fewer expert supports. It shows the knowledge hole is not just in clinics.

Lerman (2024) gives the how. The paper drafts a step-by-step blueprint to hand behavior tools to non-behaviorists like nurses and teachers. It answers the 2012 plea with a ready map.

If you write programs for adults or kids with dual diagnosis, assume the mental-health side feels under-skilled. Use the N et al. mentoring model: short weekly coaching, shared data sheets, and joint goal setting. Start with one nurse or one teacher, track integration for six weeks, then add the next team. You will turn the 2012 problem into the 2002 solution.
