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


  • To compare individual, group and combined intervention formats for improving goal attainment and psychosocial function following acquired brain injury.Randomized controlled trial, waiting list controls.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.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.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.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.
