Cognitive and interpersonal moderators of two evidence-based depression prevention programs.

Area of Science:

• Psychology
• Adolescent Mental Health
• Clinical Psychology

Background:

• Depression is a significant concern in adolescents.
• Evidence-based prevention programs exist, but effectiveness can vary.
• Identifying moderators can personalize treatment for better outcomes.

Purpose of the Study:

• To examine cognitive and interpersonal factors as moderators of two youth depression prevention programs.
• To determine if factors like rumination, negative cognitive style, hopelessness, and parent-adolescent conflict influence program effectiveness.
• To personalize the selection of cognitive-behavioral or interpersonal depression prevention strategies for adolescents.

Main Methods:

• Two hundred four adolescents were randomized to either Coping With Stress (CWS) or Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST).
• Potential moderators included rumination, negative cognitive style, dysfunctional attitudes, hopelessness, parent-adolescent conflict, negative interactions, and social support.
• Depression symptoms were assessed repeatedly for 18 months postintervention.

Main Results:

• Rumination, hopelessness, and conflict with father significantly moderated intervention effects on depression symptom change.
• High conflict with father predicted better outcomes with IPT-AST compared to CWS during follow-up.
• Low conflict with father showed different patterns, with IPT-AST leading to symptom increases and CWS to nonsignificant changes.

Conclusions:

• Cognitive factors (rumination, hopelessness) and interpersonal factors (parent-adolescent conflict) are important moderators in adolescent depression prevention.
• These findings support personalized approaches to selecting the most effective prevention program for individual adolescents.
• Exploratory analyses suggest tailoring interventions based on specific adolescent risk profiles enhances treatment efficacy.
