Peer-group interventions may inadvertently increase adolescent problem behaviors. High-risk youth are especially vulnerable to these iatrogenic effects, potentially worsening delinquency and substance use outcomes.

Area of Science:

  • Developmental Psychology
  • Adolescent Behavior
  • Intervention Science

Background:

  • Peer influence significantly shapes adolescent development.
  • Peer-group interventions aim to mitigate negative behaviors.
  • Potential for unintended negative consequences (iatrogenic effects) exists.

Purpose of the Study:

  • To examine developmental and intervention evidence for iatrogenic effects in peer-group interventions.
  • To understand how peer dynamics might exacerbate adolescent problem behaviors.
  • To identify factors contributing to negative intervention outcomes.

Main Methods:

  • Longitudinal research tracking adolescent friendships and delinquency.
  • Analysis of "deviancy training" within peer groups.

Related Experiment Videos

  • Review of two experimentally controlled intervention studies comparing peer-group interventions with control conditions.

    • Main Results:

    • "Deviancy training" in adolescent friendships predicts increased delinquency, substance use, violence, and adult maladjustment.
    • Experimentally controlled peer-group interventions led to increased adolescent problem behavior and negative adult outcomes compared to controls.
    • High-risk youth demonstrated greater vulnerability to peer aggregations than low-risk youth.

    Conclusions:

    • Peer aggregation during early adolescence can inadvertently reinforce problem behavior.
    • Specific developmental processes may underlie significant iatrogenic effects in peer interventions.
    • Careful consideration of peer dynamics is crucial for designing effective adolescent interventions, particularly for high-risk populations.
