Factors Influencing Quality of Life in the Disabled: Focus on Household Members Mental Health

Abstract Background Household members of the disabled experience various difficulties such as social isolation and the burden of caregiving. These difficulties can lead to mental health problems, which in turn affect the quality of life(QoL) of the disabled. Research on the QoL of the disabled is ongoing, but there are few studies addressing the mental health of household members. We aimed to investigate the impact of household members’ mental health on the QoL of the disabled. Methods We used data from the 2021 Disability and Life Dynamics Panel(nationwide survey). On the base of Patrick’s model of disability health promotion, we analyzed the impact of household members’ mental health on the QoL of the disabled by using correlation analysis and multiple regression analysis adjusted for gender, age, income level, employment status, education level, activities of daily living, participation in social activities, type and severity of disability, presence of multiple disabilities, and health status. Results The level of depression(r=-.316, p<.0001) and self-esteem(r=.248, p<.0001) of household members were found to be significantly correlated with the QoL of the disabled. The level of depression of household members had a significant negative impact on the QoL of the disabled(β=-.153, p<.0001), while self-esteem had a significant positive impact(β=.144, p<.0001). It was found that the level of depression had a greater impact on QoL than self-esteem. Conclusions Lower levels of depression and higher levels of self-esteem of household members are associated with higher QoL for the disabled. Improving the mental health of household members is crucial in improving the QoL of the disabled, enabling them to interact more positively with society. Additionally, as 27% of household members experience depressive issues, enhancing their mental health positively impacts on the overall well-being of families with disabilities. Efforts to enhance household members’ mental health are crucial. Key messages • Household members’ mental health significantly influences the quality of life of the disabled. • To improve the quality of life of the disabled, strengthening programs for promoting the mental health of household members and policy improvements are necessary.
