Evidence-based preventive intervention for preadolescent aggressive children: One-year outcomes following randomization to group versus individual delivery.

ABSTRACT: Some research suggests that group interventions with antisocial youth may, on occasion, have iatrogenic effects. This is the first study to test the effects of group versus individual delivery of evidence-based intervention for aggressive children.Three hundred sixty fourth-grade children were randomly assigned by school to group coping power (GCP) or individual coping power (ICP). Longitudinal assessments of teacher and parent reports of behavior (Behavior Assessment System for Children [BASC]; Peer Affiliation and Social Acceptance [PASA]) were collected from baseline through a 1-year follow-up.Growth curve analyses revealed that children in both conditions reduced teacher- and parent-reported externalizing behavior problems and internalizing behavior problems by the end of the 1-year follow-up. However, the degree of improvement in teacher-reported outcomes was significantly greater for children receiving an individual version of the program. In addition, children's baseline level of inhibitory control moderated intervention effects, showing children with low initial levels of inhibitory control to respond poorly in teacher-rated outcomes to group interventions compared to those delivered individually.This study suggests overall benefits to children for either group or individual delivery of the Coping Power program under high-fidelity conditions; however, for children with low levels of initial self-regulation, individualized interventions will likely yield the most significant reduction in externalizing behavior in the school setting in preadolescence.

Project description:BACKGROUND:Perinatal depression is a prevalent public health concern. Although preventive interventions exist, there is limited literature on the acceptability and appropriateness of these interventions, especially those delivered by paraprofessionals. The Mothers and Babies Program (MB) is a group-based perinatal depression preventive intervention delivered prenatally. A cluster-randomized controlled trial examined the acceptability, appropriateness, and effectiveness of MB delivered by mental health professionals compared to paraprofessional staff from home visiting programs. METHODS:The full study enrolled 874 pregnant women. Fifty-three facilitators were trained and delivered the MB intervention to women in one of seven states in the United States. Semi-structured interviews were attempted with a randomly-selected subset of the full sample of pregnant women who received the MB intervention and with all facilitators. Specifically, interviews were conducted with 88 women who received the MB group intervention (45 in the paraprofessional-led arm and 43 in the mental health professional-led arm) and 46 women who facilitated the groups (27 home visiting staff and 19 mental health professionals). Interviews were conducted over the phone in English or Spanish and audio recorded. The recordings were translated into English, as needed, and transcribed. Thematic analysis was conducted using NVIVO to identify key themes related to intervention acceptability and appropriateness. Similarities and differences between study arms were explored. RESULTS:Clients and facilitators found the MB content and group format acceptable. Challenges included maintaining group attendance, transportation issues, and managing group discussion. Overall, facilitators found the intervention appropriate for pregnant clients with some challenges presented for clients in crisis situations, experiencing housing instability, and with literacy and learning challenges. Participants provided suggestions for improvement, both for the course content and implementation. There were no significant differences found between study arms. CONCLUSIONS:Overall, clients and facilitators enjoyed MB irrespective of study arm, and facilitators found the intervention appropriate for the population. These findings add to the qualitative literature on perinatal depression preventive interventions, specifically those delivered by paraprofessionals. TRIAL REGISTRATION:This trial is registered on ClinicalTrials.gov (Initial post: December 1, 2016; identifier: NCT02979444).
