Gamified Adaptive Approach Bias Modification on Individuals With Methamphetamine Use History

Addiction, Substance Clinical Trial

Official title: Gamified Adaptive Approach Bias Modification on Individuals With Methamphetamine Use History

Status Completed

Clinical Trial Summary

A randomized controlled trial will be conducted to investigate whether a proposed algorithm that adjusts the congruency ratio based on the user's performance and difficulty can enhance the effectiveness of approach bias modification. Methamphetamine users will be recruited and randomized into an algorithm group, a standard group, and a control group.

Clinical Trial Description

To assess the efficacy of an adaptive approach bias modification (A-ApBM) paradigm with gamified designs and dynamic difficulty adjustments in reducing cue-induced craving in individuals with methamphetamine use history. DESIGN: Randomized controlled trial with three study groups: Adaptive ApBM (A-ApBM), Static ApBM (S-ApBM), and control. A-ApBM and S-ApBM groups engaged in ApBM training using a smartphone application for four weeks. A-ApBM used an adaptive algorithm to dynamically adjust the difficulty level based on individual performance, while S-ApBM had a static difficulty level. Cue-induced craving scores were assessed using a visual analog scale at baseline, post-intervention, and at week-16 follow-up. ;
