In Canada, correctional officers represent one of the worker populations most at risk of exhibiting suicidal behaviors (suicide ideation, planning and attempts) (Carleton et al., 2018). Despite being an important issue, the phenomenon of suicidal behaviors among correctional officers is poorly covered in the scientific literature, unlike what is found for police officers, firefighters and military personnel. From an ecological perspective of human development (Bronfenbrenner, 1979), risk factors for suicidal behaviour can be found not only at the individual level, but also in one's social, organizational and even societal environment. It is from this ecological perspective that this research aims to explore the development of suicidal behaviours among professionals in provincial correctional settings. To meet this objective, an exploratory qualitative study was undertaken with a population of provincial correctional officers in Quebec. Some twenty officers (men and women) working in different detention centers (urban and rural; male and female clientele) took part in interviews lasting an average of 60 minutes. Preliminary results fit well with the ecological model. Personal risk factors combine with social and organizational factors linked to the context and work culture of correctional officers. These results will provide food for thought regarding the prevention mechanisms to be put in place in this type of workplace.
