Comparison of individual, group and combined intervention formats in a randomized controlled trial for facilitating goal attainment and improving psychosocial function following acquired brain injury

Objective: To compare individual, group and combined interventions formats for improving goal attainment and psychosocial function following acquired brain injury. Design: Randomized controlled trial, waiting list controls. Participants: Thirty-five participants with a mean time of 5.29 years (standard deviation = 3.9) since acquired brain injury were randomly allocated into 6 groups involving an intervention or waiting list control condition for 1 of 3 intervention formats. Methods: Interventions were 3 h/week for 8 weeks. Formats included: group-based support (n = 12), individual occupation-based support (n = 11), and a combined group and individual support intervention (n = 12). Participant outcomes were examined at pre-, post-, and 3-month follow-up assessment on the Canadian Occupational Performance Measure, Patient Competency Rating Scale, and Brain Injury Community Rehabilitation Outcome 39 Scales. Results: Overall, the findings indicated that the individual intervention component appeared to contribute particularly to gains in performance in goal-specific areas. The combined intervention was associated with maintained gains in performance and satisfaction. However, gains in behavioural competency and psychological well-being were more likely to occur after the group and individual interventions. Conclusion: These findings generally support the efficacy of brief intervention formats following acquired brain injury, although further research is needed to examine clients' suitability for particular interventions. © 2007 The Authors.
