The Project on State-Level Child Outcomes, a federal project designed to improve the measurement of child outcomes in state welfare evaluations and in other state data systems. This document provides measures for the common core of constructs that state representatives developed at the second national-level meeting of the Project's planning phase. A table delineates measures for the core constructs in the areas of: (1) target of welfare policies, income, employment, and family formation; (2) other variables likely to be affected by state policies, including psychological well-being, stability and turbulence, absent parent involvement, use of health and human services, and consumption; (3) aspects of the child's environment likely to be affected by previous variables, such as child care and home environment and parenting practices; and (4) child outcomes related to education, health and safety, and social and emotional adjustment. The remainder of the document consists of proposed survey questionnaires and other measures for each core construct. (KB)
