Digital Therapies for Substance Use Disorders: Recent Advances and Engagement Strategies

Area of Science:

• Digital Health
• Behavioral Science
• Public Health

Background:

• Substance use disorders (SUDs) are prevalent chronic conditions often lacking adequate treatment.
• Digital interventions, including mobile apps, have increased access to SUD care, a trend accelerated by the COVID-19 pandemic.
• Sustaining user engagement remains a critical challenge for digital therapeutics in SUD treatment.

Purpose of the Study:

• To review evidence on digital interventions for SUDs, focusing on mobile applications.
• To identify factors differentiating effective SUD apps from less successful ones.
• To propose strategies for improving user engagement in digital therapeutics for SUDs.

Main Methods:

• A narrative review of literature published between 2013 and 2025 on digital SUD interventions.
• Inclusion of randomized trials, systematic reviews, and observational studies of SUD-focused apps.
• Analysis of engagement tactics from mobile gaming and other app domains.

Main Results:

• Efficacious apps integrate evidence-based therapy, personalized feedback, craving management, and support connectivity.
• Apps lacking interactive content show minimal benefit.
• Engagement strategies like gamification, incentives, social features, and care integration boost retention and clinical results.

Conclusions:

• Mobile apps show promise as adjuncts for SUD treatment, contingent on user engagement.
• Incorporating rewards, personalized interventions, social support, and provider involvement enhances engagement.
• Improved engagement with digital therapies for SUDs leads to better long-term recovery outcomes.
