Objective: To investigate caregiver ratings of behavioral control after an intervention focused on coping and compensation skill development for patients with acquired brain injury (ABI) and their caregivers. Method: Patients with ABI (Stroke = 5, TBI = 2, other = 2) and their 9 caregivers were recruited from our brain rehabilitation clinic who underwent an evidence-based 12-session Brain Injury Coping Skills program focused on development of coping and compensation skills. All caregivers completed the Frontal Systems Behavior Scale (FrSBe) immediately before and after the intervention. Results: All dyads completed the 12 session program. Mean age of patient = 64.67 years, Range: 41-76 years. Mean time since injury = 3 years, Range: 9 months–9 years. One-way within-subjects ANOVA was conducted with pre-injury, pre-intervention, and post-intervention scores as the factors evaluating the apathy, disinhibition, executive dysfunction subscales on the FrSBe. A significant time effect was noted, Wilks' Λ = 0.11, F (8, 24) = 5.58, p < 0.001, multivariate η2 = 0.67. Follow-up polynomial contrasts show a significant linear effect with decreasing means over time for all subscales. There was a significant change from pre-injury to pre-treatment for all subscales; however, only apathy scale showed significant improvement post-intervention (p = 0.012). Conclusion: The small sample size in this pilot study limits the conclusions drawn from these findings. Consistent with the literature, results reflect significant increase in apathy, disinhibition, and executive dysfunction in patients with ABI post-injury. Overall, caregivers report increased behavioral activation in their family member with ABI after this intervention, which may be a result of attending a group-based intervention for 12 weeks.
