This study will employ cognitive behavioral therapy for insomnia (CBT-I) among individuals with mild traumatic brain injury (mTBI) who experience sleep disturbances. The research aims to evaluate the effects of CBT-I on sleep, mTBI symptoms, and, in particular, the ability of individuals with mTBI to engage in their desired daily life activities. The main questions this study aims to answer are:
1. Does CBT-I positively impact symptoms of mTBI? 2. Does CBT-I improve functional performance in individuals with mTBI?
