Program and treatment evaluation in the domains of mental health and addiction, with a particular interest for the evaluation of the perspectives of clientele; Development, implementation and evaluation of training programs for staff and peer helpers in addiction and mental health.

Michel Perreault, PhD, is a psychologist and researcher at the Douglas Institute since 1986 and an associate professor in the department of psychiatry at McGill University since 1994. His research aims to evaluate services and treatments in psychiatry, with the goal of improving them. He is a researcher with the Groupe de recherche et intervention sur les substances psychoactives-Québec (RISQ) and at the Institut universitaire sur les dépendances (IUD), and also a member of the Quebec Pain Research Network (QPRN).

Working within a clinical environment, Michel Perreault and his team develop projects involving applied research on treatments, organization and evaluation of services in psychiatry and addiction. He is particularly interested in persons having concurrent mental health and substance use disorders and the integration of the services that are intended for them. Since 2002, he is responsible for a cross-training program that aims to improve the functioning of services within a network involving services for mental health and substance use. The program has included over 5900 participants since its beginnings, and is currently being implemented in other regions. The content from the exchange sessions has also been adapted to develop online training modules, which will be posted on the program’s website (formationcroisee.com). Michel Perreault is also one of the initiators of the user panel at the Douglas Institute, which started in 2002.

Michel Perreault is also responsible for the evaluation of numerous treatments and programs related to substance use, some of which involve persons with an opioid dependency or users of injectable drugs. He is also interested in the evaluation of interventions led by peer helpers for this clientele and for those having anxiety disorders, in the form of self-treatment groups.
