Due to the chronic effects and neurological basis of substance use disorder, medical and holistic interventions are needed to address the disorder. Individuals with substance use disorder feel an impact to their occupational functioning and overall engagement in daily activities and may lack the ability to participate in meaningful tasks without the use of substances. As the individual's substance of choice becomes their ‘primary occupation’, daily activities and routines can be removed or altered to make space for their chosen occupation. Occupational therapy takes a comprehensive approach to treatment and aims to treat all areas of occupational dysfunction, including those caused by their addiction. Occupational therapy should be considered as a recovery approach because substance use negatively affects an individual’s occupational engagement and everyday tasks. Findings from this capstone project highlight the benefits of occupational therapy in substance abuse rehabilitation facilities.
