Digital Game May Reduce Adolescent Depression Symptoms

Key Takeaways

• Higher-risk adolescents in Connecticut school-based health programs had lower depressive symptoms over follow-up after assignment to a 6-week digital behavioral health game than after assignment to an attention-matched control.
• The depression signal was modest and remained statistically significant by 12 months.
• Anxiety symptoms measured with the GAD-7 were not significantly associated with the intervention.
• Beliefs about psychological services improved at 6 weeks, and exploratory mediation linked early BAPS improvement with lower PHQ-8 scores at 6 months, while other psychosocial and moderation findings were not associated with the intervention.

Depression and anxiety in adolescence remain common and impairing, and school-based programs continue to look for scalable support that feels engaging rather than overtly clinical. Digital tools may help extend mental health support for higher-risk youth who face barriers to consistent care, including those with substance use or elevated symptoms. Against that backdrop, investigators tested a youth-codesigned behavioral health game in Connecticut school-based settings.

In a JAMA Network Open secondary analysis of a digital behavioral health game trial in adolescents, investigators conducted a prespecified secondary analysis of a randomized clinical trial with assessments from baseline through 12 months. Eligible adolescents from 15 Connecticut school-based health programs were 16 to 19 years old if they reported past-30-day alcohol, cannabis, vaping, or other nonopioid substance use or had elevated depression and/or anxiety symptoms. Among 532 participants, 269 were assigned to the intervention and 263 to an attention-matched active control, with approximately 300 minutes of gameplay delivered during 6 weeks. Prespecified secondary outcomes included depressive symptoms on the 8-item Patient Health Questionnaire (PHQ-8), anxiety symptoms on the 7-item Generalized Anxiety Disorder scale (GAD-7), and psychosocial measures including beliefs about psychological services (BAPS).

PHQ-8 scores showed a group-by-time interaction (F3,1308 = 2.93; P = .03). At 12 months, adjusted mean PHQ-8 scores were 5.30 in the intervention group and 6.42 in the control group, with an adjusted difference of -1.12 points (95% CI, -1.85 to -0.38). No association was detected for GAD-7. At 6 weeks, BAPS scores were higher in the intervention group (adjusted difference, 0.03 [95% CI, 0.01-0.05]), and exploratory mediation associated early BAPS improvement with lower PHQ-8 scores at 6 months.

Overall, the authors concluded that the digital game was associated with modest, sustained reductions in depressive symptoms during follow-up. The psychosocial pattern was consistent with improved beliefs about psychological services as one possible contributor to short-term symptom change. They framed digital games as a potentially scalable support for adolescent mental health in school-based settings.

Clinician Questions

Which adolescents were included in the digital behavioral health game trial?

The trial included adolescents aged 16 to 19 years from 15 Connecticut school-based health programs who reported past-30-day alcohol, cannabis, vaping, or other nonopioid substance use or had elevated depression and/or anxiety symptoms. The findings therefore apply to a higher-risk school-based population and do not establish the same effect in all adolescents.

What psychosocial outcome changed early with the digital game, and how was it linked to later depressive symptoms?

Beliefs about psychological services (BAPS) were higher at 6 weeks in adolescents assigned to the digital game, and exploratory mediation associated that early BAPS improvement with lower PHQ-8 scores at 6 months. Because the mediation analysis was exploratory, it suggests a possible pathway rather than proving a mechanism.

Did the digital behavioral health game improve anxiety symptoms as well as depressive symptoms?

No association was reported for anxiety symptoms on the GAD-7, even though depressive symptoms were lower over follow-up in adolescents assigned to the digital game. The findings therefore suggest a depression-specific signal rather than parallel improvement across both symptom domains.
