Brief Web-Based Psychological Intervention for Depressive Symptoms Among Chinese Adolescents: Randomized Controlled...

Area of Science:

• Digital mental health interventions
• Adolescent psychology
• Clinical trial research

Background:

• Adolescents with depressive symptoms face social impairment and increased risk of major depressive disorder.
• Web-based interventions offer accessibility but their effectiveness for adolescent depression is under-researched.
• Chinese adolescents have unique developmental and psychological needs for mental health support.

Purpose of the Study:

• To develop a brief, web-based psychological intervention for Chinese adolescents.
• To evaluate the intervention's effectiveness in reducing depressive symptoms.
• To identify factors influencing the intervention's outcomes.

Main Methods:

• A 2-arm randomized controlled trial involving 436 adolescents (12-18 years) with depressive symptoms.
• Intervention group received 4-week emotional cognitive training; control group received psychoeducation.
• Outcomes included depressive symptom severity, remission rates, anxiety, suicidal ideation, and resilience, assessed over 3 months.

Main Results:

• No significant difference in depressive symptom severity between groups over 3 months.
• Exploratory analysis: higher remission rate in the intervention group for adolescents with anxiety (NNT=7).
• Intervention group showed improved interpersonal support resilience, mediating depressive symptom remission.

Conclusions:

• The brief web-based intervention did not outperform psychoeducation for general depressive symptom reduction.
• Exploratory findings suggest potential benefits for adolescents with comorbid anxiety.
• Interpersonal support may be a key factor in tailoring future digital mental health interventions.
