Volume I contains a literature review, empirical paper, and public domain paper. The literature review is on the subject of spousal relationships following acquired brain injury, and evaluates the evidence on demographic and other predictors of relationship stability and quality post-injury. The empirical paper is a follow-up study investigating the links between carer expectations, wellbeing, and involvement in acquired brain injury rehabilitation, and the associations between these factors and clinical outcomes for the person with the injury. The public domain paper represents an accessible summary of the empirical paper.
