- Hypothesis: (1) we intended to examine whether the traditional therapy (anodal tDCS over right DLPFC, cathodal tDCS over left DLPFC, with drug cues exposure) could effectively reduce the subjective craving. (2) We tested whether the new method (anodal tDCS over left DLPFC, cathodal tDCS over right DLPFC, with negative self-appearance exposure) could enhance self-concept and reduce drug craving. (3) And to see whether the stimulation effect on drug craving and relapse of new method would be longer. Data Collection: 54 amphetamine addicts were randomized to three groups (self group, anodal tDCS on left dorsolateral prefrontal cortex (DLPFC) with self-picture presentation; drug group, anodal tDCS on right DLPFC with drug pictures presentation; control group, routine treatments as usual) for a 40-day tDCS (10 sessions, 2mA, 15min) treatment. Levels of drug craving and self-concept were measured before, immediately after and 6 months after the intervention.Demographic information was also included. Results: Compared to control group, drug craving in two experimental groups significantly decreased after stimulation, and self-concept in self group significantly increased. 6-month follow-up measurement showed that treatment effect on both drug craving and self-concept remained in self group. While the direct effect of tDCS in drug group failed to endure in the 6-month follow-up. Conclusions: This study explored a new protocol of addiction treatment. Improving self-concept seems more effective than direct intervention of cue-induced drug craving, which can not only reduce drug craving, but also enhance participant’s ability to resist drug relapse. Self-concept maybe an important psychological construct for drug abuse. Data description: Except for using a visual analog scale (VAS) to assess their subjective drug craving and self-concept, we also used Obsessive Compulsive Drug Use Scale and Self-esteem Scale to measure drug craving and self-esteem respectively. Total score and every item score were reserved in our dataset.
