This paper considers methodological issues related to the independent variable in early intervention research. Three standards are proposed: (1) use theory to guide research; (2) provide operational definitions of independent variables, quantify them, and describe how they relate to theory; and (3) measure treatment fidelity. Three levels of…

In response to O'Brien et al., who examined predictors of child outcome among at-risk infants as possible eligibility criteria for early intervention programs, this paper notes that most biological risk factors in infants are not adequately predictive of developmental dysfunction. It stresses that when social problems are the cause of…

In response to O'Brien et al., who examined predictors of child outcomes among at-risk infants, this article suggests that the goal of prevention and early detection can be more efficiently met if the focus shifts from prediction to ongoing monitoring of children's developmental growth. A three-step model involving ongoing screening, eligibility…

This article comments on a study that found children (ages 0-3) who were disadvantaged, from minority groups, or without health insurance were 2 to 30 times more likely to have unmet health care needs. The "medical home" philosophy is discussed, in which medical care is accessible, comprehensive, and family centered. (Contains 8 references.) (CR)
