Effects of group versus individual therapy for patients with memory disorder after an acquired brain injury: A randomized, controlled study

ABSTRACTIntroduction: This randomized, controlled, single-blind study compared the efficacy of group versus individual memory rehabilitation therapy for patients with acquired brain injury (ABI). Subjects (N = 65) were assigned to individual (IT), group (GT), or no (NT) therapy during the three-week rehabilitation program. A neuropsychological assessment was conducted before treatment, immediately after completing treatment, and 4 months after completing treatment. Three levels of functioning were assessed: participation, disability, and impairment. The primary outcome measure was the Rivermead Behavioural Memory Test (RBMT). The results of the cognitive measures in the three groups at subsequent assessments were compared, and the effect sizes were calculated to investigate the magnitude of improvement.Results: There were no significant changes in self-reported patient memory problems for the participation-level measures. However, relatives of participants in the GT group reported a decreased frequency of...
