Relationship between perception of healthcare services and health-related quality of life in mothers of children with disabilities.

[Purpose] To clarify the relationship between mothers' health-related quality of life and their perceptions of healthcare services, including physical therapy, for their children with disability, along with factors affecting health-related quality of life. [Participants and Methods] Survey items were the Short Form Health Survey, Measure of Processes of Care 56, as an indicator of the perception of healthcare services, type of disability and activities of daily living, and the mother's sleep patterns and employment status. The correlation between health-related quality of life and service perceptions was investigated. Further, multiple regression analysis was conducted by combining the child's and mother's statuses as an interaction term. [Results] The mental component summary score of the Short Form Health Survey showed a significant weak positive correlation with Measure of Processes of Care 56. The number of awakenings from sleep at night was found to be a significant moderator of the physical component summary score of the Short-Term Health Survey and showed a limited but significant effect on the 'providing general information' domain of Measure of Processes of Care 56. [Conclusion] Mothers with a low awareness of 'providing general information' and a high number of times waking from sleep at night tended to show low health-related quality of life.
