Digitally managing depression: A fully remote randomised attention-placebo controlled trial

Area of Science:

• Digital health interventions
• Mental health technology
• Clinical psychology

Background:

• Depression is a prevalent and debilitating mental health condition.
• Digital applications offer potential to augment mental healthcare, especially for underserved populations.
• The efficacy of digital self-management tools for depression requires rigorous evaluation.

Purpose of the Study:

• To evaluate the efficacy of the juli digital self-management app for depression.
• To compare the juli app's effectiveness against a limited attention-placebo control app.
• To assess outcomes including symptom reduction, remission rates, and quality of life.

Main Methods:

• A pragmatic, fully remote randomized controlled trial was conducted.
• Participants (aged >18) with self-identified depression (PHQ-8 score >5) were randomized (1:1) to juli or a control app for 8 weeks.
• Primary outcome: difference in Patient Health Questionnaire-8 (PHQ-8) scores at 8 weeks; secondary outcomes included remission and quality of life.

Main Results:

• In the per-protocol analysis, the juli group showed a statistically significant greater reduction in PHQ-8 scores compared to the control group (p=0.045).
• Remission and minimal clinically important difference were significantly more likely in the juli group (p<0.001 and p=0.018, respectively).
• No significant differences were observed in health-related quality of life or worsening of depression between groups.

Conclusions:

• The juli app demonstrated a small but statistically significant reduction in depression symptoms over 8 weeks compared to an attention-placebo control.
• The findings suggest juli is a viable digital self-management tool that could enhance accessibility to evidence-based depression treatments.
• Further research may explore long-term effects and effectiveness in diverse populations.
