NCT07319325

Brief Summary

This study evaluates the efficacy of a comprehensive, adaptive digital therapeutics (DTx) smartphone application compared to treatment as usual (TAu) for individuals with Methamphetamine Use Disorder (MUD) receiving community-based rehabilitation. The intervention integrates Internet-based Cognitive Behavioral Therapy (ICBT), adaptive Approach Bias Modification (A-ApBM), cognitive training, and contingency management. The primary hypothesis is that the DTx intervention will result in a greater reduction in cue-induced craving compared to standard community care.

Outcome Measures

Primary Outcomes (1)

  • Change in Cue-Induced Craving Score

    Self-reported craving elicited by standardized methamphetamine-related images, measured using a Visual Analog Scale (VAS). Scores range from 0 to 100, with higher scores indicating higher craving. The outcome is defined as the change in score from Baseline to Week 8.

    Baseline and 8 Weeks (Post-intervention)

Study Arms (2)

Adaptive Digital Therapeutics (DTx)

EXPERIMENTAL

Participants receive access to WonderLab Harbor+ (Adaptive DTx), a smartphone application, for 8 weeks. They are instructed to complete one ICBT session per week (approx. 10 mins) and one Adaptive Approach Bias Modification (A-ApBM) session daily (approx. 3 mins). The app also includes cognitive training games and a rewards system (Contingency Management). This is provided in addition to standard community care.

Device: WonderLab Harbor+ (Adaptive DTx)

Treatment as Usual (TAU)

ACTIVE COMPARATOR

Participants receive standard care provided by the community rehabilitation centers, which consists of counseling sessions (in-person or telephone) delivered by social workers covering stress management, family issues, and craving suppression.

Behavioral: Standard Community Counseling

Interventions

Participants receive access to a smartphone application for 8 weeks. They are instructed to complete one ICBT session per week (approx. 10 mins) and one Adaptive Approach Bias Modification (A-ApBM) session daily (approx. 3 mins). The app also includes cognitive training games and a rewards system (Contingency Management). This is provided in addition to standard community care.
