In the 6th grade, approximately half of the group (n = 500) were randomly assigned to a family-centered intervention and were offered participation in the Ecological Approach to Family Intervention and Treatment (EcoFIT). Although potential intervention effects were not a focus of this study, we tested for differences in the results across the intervention and control group, so a brief description of this program is in order. The intervention, described in greater detail elsewhere (Connell et al. 2007; Dishion and Kavanagh 2003; Dishion and Stormshak 2007), is a multilevel (universal, selected, indicated), ecological approach to family engagement and intervention implemented in the public school environment.
