OBJECTIVES: The purpose of this study was to examine whether a brief structured multicomponent group programme for carers of people with acquired brain injury (ABI) was effective in reducing carer distress, strain, and critical comments between carer and person with an ABI compared to a waiting list control condition. DESIGN: Waiting list controlled study. Pre- and post-test design with outcomes measured at induction, at the end of the intervention, and at the 3-month follow-up.
