Relationships between parent ratings of Part C/early intervention (EI) services and family outcomes for families of young children with disabilities were examined--specifically, the early childhood outcomes (ECO)-recommended family outcomes and family quality of life (FQOL). Measures included the Early Childhood Services Survey, the ECO Center Family Outcomes Survey, and the Beach Center Family Quality of Life Scale. Findings support a logic-model relationship between parent ratings of Part C/EI services, ECO-recommended family outcomes, and FQOL. Parent ratings of Part C/EI services were found to predict immediate family outcomes as measured by ECO-recommended family outcomes, and ECO-recommended family outcomes, in turn, predicted the broader outcome of enhanced FQOL. Implications for EI practice and evaluation are discussed. (Contains 7 tables and 2 figures.)
