Abstract: Currently in Canada, more than one million people are living with the sequelae of an acquired brain injury. The incidence of brain injury outnumber breast cancer, AIDs, spinal cord injury and multiple sclerosis - combined. Traumatic brain injury (TBI) is now considered a chronic medical condition and a major public health concern whose consequences can persist and progress. Although depression is one of the psychological disorders with the highest prevalence rates post-TBI, there are few studies of nonpharmacological interventions for this issue. This lack of empirical evidence has a direct impact on TBI patients, leaving them without recognized efficacious treatment adapted to the specificities of their condition. Behavioural Activation (BA) has been demonstrated to be as effective as cognitive behaviour therapy (CBT) but is less cognitively demanding and thus potentially more suitable for people with brain impairment. However, no study has been yet done to verify its feasibility and efficacy in the TBI population. The objective of this single-case study was to preliminary evaluate the feasibility and efficacy of BA administered in a low-intensity guided self-help format for depressive symptoms in adults (18 years and older) having sustained TBI, using a single-case experimental design. This study also aimed to evaluate the potential benefits of BA regarding quality of life and social participation. Five participants with clinically significant depressive symptoms were enrolled in the study and were asked to complete mood assessments during the baseline, treatment and follow-up. Only two of them completed the entire protocol. This project demonstrated the feasibility of BA intervention on mild to moderate depression symptoms in adults with mild TBI. Modest evidence in support of BA to decrease depressive symptoms and quality of life was found but BA had no effect on social participation.
