Study Overview
Brief 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.
Detailed 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.

Outcomes
Primary Outcomes
Cue induced craving for methamphetamine
Time Frame: 16 week from baseline assesment
The cue-induced craving was assessed by showing the participants images related to methamphetamine (methamphetamine crystals, powders, and paraphernalia) on a smartphone and asking them to rate their cravings on a 0-10 visual analog scale (0 being least craved and 10 being most craved).
