This article explores service use broadly by examining the mix of educational, health, and psychosocial services that preschool children received in the fifth year of life. The sample included 869 children who participated in the Infant Health and Development Program, an early intervention program designed to evaluate the efficacy of a comprehensive early intervention for low-birth-weight, premature infants during the first 3 years of life and who were followed until age 5. Cluster analyses of services at age 5 yielded 4 service groups--basic health only (doctor visits; n = 114); basic health and educational services (doctor visits and school/preschool; n = 444); basic health, educational, and psychosocial services (or multiple services; doctor visits, school/preschool, and psychosocial services; n = 129); and specialized health and educational services (doctor visits, school/preschool, emergency room visits and special medical visits [ear and/or eye examinations]; n = 182). Results suggest that neonatal health conditions, maternal education at the time of the child's birth, child developmental status at age 3, and maternal health, family income, and insurance status at age 5 were associated with patterns of services at age 5. Patterns of use are consistent over time (the first 3 years of life to the 5th year of life). After covarying the correlates of the service patterns, participation in the early intervention was not associated with patterns of services at age 5, and service patterns were associated with child well-being (health, school readiness, mental health), but results differed by intervention status. Findings are discussed in terms of preventive, responsive, and deficit models of service use.
