Study Participants

The study included 731 families that met two criteria. Firs, they participated in the Supplemental Nutrition Program for Women, Infants, and Children (WIC) when their son or daughter was between 2 years 0 months old and 2 years 11 months old. Second, they met the study’s criteria for being at risk for behavior problems—defined as one standard deviation or more above normative averages in at least two of three domains: (1) child behavior problems (for example, conduct problems or high-conflict relationships with adults); (2) primary caregiver problems (for example, maternal depression, daily parenting challenges, self-report of substance or mental health diagnosis, or status as a teen parent at first birth); and (3) socioeconomic status (a caregiver with low educational achievement or low family income based on WIC criteria). Screening was conducted in 2002 and 2003. Of the 731 primary caregivers who agreed to participate, 50 percent were European American, 28 percent were African American, 13 percent were biracial, and 9 percent were from another racial group. Thirteen percent were Hispanic. More than two-thirds of the randomized sample had an annual income below $20,000. Forty-one percent of the sample had a high school diploma or GED and 24 percent had less than a high school diploma or GED. The 731 children in the study were 29.9 months old on average at the time of the age 2 assessments. Forty-nine percent of the children were female and 58 percent lived in two-parent households.

Setting

Families were recruited from WIC program sites in and around Pittsburgh, Pennsylvania (37 percent of sample); Eugene, Oregon (37 percent of sample); and Charlottesville, Virginia (26 percent of sample).

Intervention condition
Comparison Conditions

Notes from the review of this manuscript

In addition to the reported outcomes that rated moderate, several outcomes in this study rated low: child noncompliance at ages 3, 4, and 5; dyadic coercion at ages 3, 4, and 5; and three outcomes analyzed from ages 2 to 5 with an intent-to-treat approach: oppositional/aggressive behavior, child noncompliance, and dyadic coercion. These outcomes rated low because we could not assess attrition or baseline equivalence based on information reported in the study, nor was it available from the author. HomVEE reports results for interventions delivered to families with children from birth to kindergarten entry. Given that the FCU intervention continued to be delivered to families at the time of later assessment, child and parent outcomes reported within this study that were assessed after children were age 5 were excluded from review. This study is part of a large RCT described by Dishion et al. (2008).
