The Impact of Income and Social Capital on the Health of People with Developmental Disabilities

Abstract

This study examines the impact of income and social capital on the health of people with developmental disabilities, focusing on the moderating effects of income and social capital on health. Hierarchical regression analysis was conducted using data from 235 people with developmental disabilities who participated in the second wave of the Disability and Life Dynamics Panel. The findings show that people with developmental disabilities who were female, employed, and did not have multiple disabilities and chronic diseases were more likely to display higher levels of self-rated health. Furthermore, self-rated health was higher in those earning a higher income. The social network had a significantly positive effect on health, but its moderating effect on the impact of income did not carry statistical significance. Trust was found to have a moderating effect on the impact of income on health, where the group with greater trust and lower income was healthier than the group with lower trust. The findings suggest the need to provide income support and establish social capital for people with developmental disabilities to improve their health, and this study offers related policy implications.
