People with a traumatic brain injury and who present with an unsafe or problematic substance use of psychoactive substances (PAS) face specific challenges in social integration resulting from the negative impacts of substance use on the benefits of rehabilitation services and treatments.

A systematic review of grey and scientific literature was conducted. The selection and coding of the included interventions (according to their characteristics), as well as descriptive analyses, resulted in findings which describe the interventions under study. Grades of evidence strength were attributed to the findings based on a range of factors including the methodological characteristics of the studies. Findings resulting from the systematic review were contextualized with information collected from administrative databases, clinical program documentation, and experiential data obtained from rehabilitation professionals. Recommendations were elaborated based on the aggregated data sources and informal deliberations by a committee involving researchers and clinicians.

Out of 5014 selected references, 14 studies examining 13 interventions which targeted social integration of the management of PAS were included. Interventions with the strongest evidence base are user-centered (i.e., support individual choices and personal autonomy), individualized (i.e., considered individual needs and characteristics), and educational (i.e., support the acquisition of strategies and abilities). The evidence base was considered “emerging” for interventions which are systemic in nature (i.e., relate to familial, social, cultural, educational or professional environments), interdisciplinary (i.e., involve clinicians with distinct training, competences and expertise), and ecological (i.e., which involve interventions in the client’s living settings). While additional research is necessary to better support their efficacy, these interventions exhibited promising effects on various outcomes.

The analysis and synthesis of three streams of information resulted in five clinical practice recommendations relating to integration to school and productive activities, psychological adaptation, integration in living settings and independence, social life and sense of belonging, and finally, use of PAS. Recommendations should help support clinicians in rehabilitation settings.
