The aim of this study was to examine the attributable risk of low income for child psychosocial morbidity. Data on 1,996 6- to 16-year-old participants from the Ontario Child Health Study, a province-wide cross-sectional study done in 1983, were used. Out-comes measured included psychiatric disorders, poor school performance, chronic health problems, and social impairment. The attributable risk for low income and child psychosocial morbidity was generally small except among selected disorders in younger children. The implications of these findings are discussed.
