We examined the longitudinal effects of community risk and protective factors on asthma morbidity and healthcare utilization. Three hundred urban caregivers of children with poorly controlled asthma were enrolled in a randomized controlled trial testing the effectiveness of a behavioral/educational intervention and completed measures of exposure to community violence (ECV), social cohesion (SC), informal social control (ISC), child asthma control, child asthma symptom days/nights, and healthcare utilization.

Building evidence of effective practice in child welfare requires practitioners and researchers to know the extent to which programs are implemented in order to understand evaluation results. Fidelity monitoring is a critical strategy for ensuring that evidence-based and promising practices are implemented as intended and can be studied in real-world contexts. This paper addresses challenges to measuring fidelity in child welfare systems and presents an approach taken with one state to define fidelity criteria and measure fidelity to a child safety intervention.

This study examined the relations among community violence exposure, inter‐partner conflict and informal social support and the behaviour problems of pre‐schoolers, and explored how mothers' parenting skills and children's social skills may mediate the child outcomes associated with such exposure.

The impact of early postnatal lead exposure measured at age 4 on children's IQ and academic achievement at and 11 years of age was examined. The sample consisted of 278 inner-city, primarily African American children who were polydrug exposed prenatally. Regression analyses indicated a linear effect of lead exposure on outcomes and no moderating effects of polydrug exposure. An IQ loss of about 4.1–5.4 Full Scale IQ points was estimated for each 10 µg/dL increase in blood lead level at ages 4, 9, and 11 years as a function of blood lead level at age 4.

Study investigated the relationship between the severity-based definition of bronchopulmonary dysplasia (BPD), choice of treatment, and neurocognitive outcomes at age 3 and 8 years. This is a secondary analysis of data collected from a prospective, longitudinal sample of 99 children with a history of BPD.
