A Single-Session, Web-Based Parenting Intervention to Prevent Adolescent Depression and Anxiety Disorders: Randomized...

Area of Science:

• Mental Health
• Developmental Psychology
• Public Health

Background:

• Adolescent depression and anxiety disorders represent a significant public health concern.
• Parenting plays a crucial role in preventing these disorders, yet evidence-based interventions are lacking.
• A tailored, web-based psychoeducation program was developed to address this gap.

Purpose of the Study:

• To evaluate the short-term impact of a novel web-based parenting intervention.
• To assess changes in parenting risk and protective factors.
• To examine effects on adolescent depression and anxiety symptoms.

Main Methods:

• A single-blind, randomized controlled trial was conducted comparing the intervention to a waitlist control.
• The intervention involved a single-session, automated, tailored psychoeducation based on online self-assessment.
• 349 parents and 327 adolescents (aged 12-15) participated, with assessments at baseline, 1-month, and 3-month follow-up.

Main Results:

• Parents in the intervention group showed significant improvements in parenting factors compared to controls (P<.001).
• Effect sizes for improved parenting were small to medium at 3-month follow-up (d=0.33).
• No significant improvements were observed in adolescent-reported parenting or adolescent depression/anxiety symptoms.

Conclusions:

• The web-based intervention effectively improved parenting practices associated with adolescent mental health.
• Short-term results do not support the intervention's effectiveness in reducing adolescent depression or anxiety symptoms.
• Further long-term studies are needed, but the intervention shows promise as a scalable prevention strategy.
