Sedentary behaviours among adults with intellectual disabilities have not been well studied. A sedentary lifestyle puts adults with and without disabilities at high risk of developing health conditions and diseases. Current literature revealed few empirical studies on the benefits of reducing sedentary behaviours with respect to the health of adults with intellectual disabilities. This research explored the factors that helped or hindered sedentary behaviours of adults with intellectual disabilities in the Canadian population. Guided by the socio-ecological model, Critical Incident Technique (CIT) was conducted. Five adults with intellectual disabilities from the Province of Ontario were interviewed and 102 critical incidents were collected. Adults with intellectual disabilities identified personal and environmental related factors that led to increased sedentary behaviours; and revealed helpful factors and wish-lists of actions that decreased sedentary lifestyle. Findings may be useful when developing programs aimed to decrease prolonged periods of sedentary behaviours specific to this vulnerable population.
