The purpose of the study was to examine the effectiveness of an intervention for parents of children with disabilities in a controlled study focusing on parents' self-efficacy, psychological well-being and perceptions of change in children's sleeping, eating and mobility. The Training and Support Programme (TSP) was designed to equip parents with a simple massage skill that they could use with their children in the home environment. Parents were trained in massage by therapeutic massage therapists in 8-weekly sessions, each lasting 1h. The sample comprised 95 parents (49 in the Intervention Group, 46 in the Waiting-list Control Group) who attended the TSP with their children. Data were collected by self-administered questionnaires at baseline (before commencing the TSP), and at 8-week follow-up. The TSP demonstrated statistically significant positive effects on parents' anxious mood, self-efficacy for managing children's psychosocial well-being, self-efficacy in giving massage therapy, and perceptions of children's sleeping and eating. Relatively high levels of psychological distress were found among parents, particularly mothers. Overall, findings suggest that wider implementation of the Programme is warranted, and greater attention needs to paid to the psychological well-being of parents caring for children with disabilities.
