Long-Term Efficacy of a Mobile Mental Wellness Program: Prospective Single-Arm Study

Area of Science:

• Digital Mental Health
• Behavioral Science
• Public Health

Background:

• Rising psychological distress necessitates effective interventions.
• Smartphone apps offer accessible mental wellness solutions, but evidence of efficacy is limited.
• Noom Mood, a CBT and mindfulness-based app, is evaluated for its impact on mental wellness.

Purpose of the Study:

• To evaluate the efficacy and post-intervention outcomes of the Noom Mood smartphone application.
• To address the increasing rates of psychological distress in the US adult population.

Main Methods:

• A 1-arm study design with 273 participants over 16 weeks.
• Surveys conducted at baseline, weeks 4, 8, 12, 16, and a 32-week follow-up.
• Assessed anxiety, depression, stress, well-being, quality of life, coping, emotion regulation, sleep, and productivity.

Main Results:

• Significant reductions in anxiety, depression, and stress observed by week 4 and sustained through 32 weeks.
• Clinically relevant reductions in anxiety and depression criteria were maintained.
• Improvements in work productivity, sleep quality, and emotion regulation were significant.

Conclusions:

• Noom Mood shows a promising positive impact on mental health and well-being outcomes beyond the intervention period.
• Smartphone-based interventions can potentially reduce barriers to mental health support.
• Further research is needed on mechanisms, scalability, and long-term adherence across diverse populations.
