Pragmatism in modeling peer influence: dynamics, outcomes, and change processes

Area of Science:

• Developmental psychopathology
• Adolescent psychology
• Intervention science

Background:

• Deviant peer involvement is a significant predictor of adolescent problem behaviors, including substance use, delinquency, and violence.
• Aggregating high-risk peers in interventions can lead to detrimental iatrogenic effects.
• Understanding the role of adults, particularly parents, is crucial for mitigating negative peer influences.

Purpose of the Study:

• To review the model-building approach in developmental psychopathology concerning peer influence on adolescent problem behavior.
• To present findings from a 4-year prevention trial examining family-centered services' impact on deviant peer involvement.
• To clarify the role of parental interventions in reducing adolescent engagement with deviant peers.

Main Methods:

• Longitudinal evidence and randomized intervention trials were reviewed.
• A 4-year prevention trial was conducted with a multiethnic middle school sample.
• Participants were randomly assigned to family-centered services within a school Family Resource center.

Main Results:

• Random assignment to family-centered services resulted in reduced growth in deviant peer involvement.
• The extent of the parenting intervention positively correlated with reduced deviant peer involvement, particularly for high-risk youth.
• Findings support the efficacy of family-centered approaches in addressing peer influences.

Conclusions:

• Family-centered services are effective in reducing adolescent deviant peer involvement.
• Parenting interventions play a vital role in structuring adolescents' peer environments and preventing problem behaviors.
• Future intervention trials should further explore the role of adults in managing peer influences.
