简要总结
Drug addiction persists as a significant global social concern with a negative impact on social harmony and stability that cannot be ignored. After returning to society, individuals with drug addiction often suffer from impaired creative problem-solving abilities and difficulties in interpersonal cooperation. The difficulties in survival stress and the sense of helplessness triggered by these factors are important reasons that lead them to seek drugs repeatedly and even to commit criminal behaviors. Therefore, enhancing creative realistic problem-solving abilities emerges as a pivotal pathway for drug addicts to facilitate rehabilitation from drug addiction and achieve societal adaptation. The project emphasizes both individual and collaborative creative solution generation for realistic problem solving. The abnormal cognitive neural mechanisms and interpersonal neural mechanisms will be systematically explored by using multiple cognitive and neuroimaging methods, such as functional near-infrared spectroscopy (fNIRS), electroencephalography (EEG), and eye-tracking. From the cognitive-behavioral-brain level, a comprehensive neurophysiological multimodal predictive model of how drug addiction affects creative realistic problem-solving will be constructed by multi-level data fitting modeling. Building upon this research foundation, The investigators will further implement single and repeated sessions of transcranial direct current stimulation (tDCS) targeting damaged brain regions for the intervention of individual and collaborative problem-solving ability under the effect of drug addiction. The indicators of brain, cognition, and behavior will be tracked at multiple time points.

研究组 & 干预措施
Active group
The study was sham-controlled, randomized, and double-blind. Participants with HUD were randomly assigned to either the active or sham groups. The DC-STIMULATOR PLUS (neuroConn, Germany) was used to deliver stimulation via saline-soaked sponge electrodes (25 cm², 5×5 cm, 1.5 mA). The stimulation in the active group lasted for 20 min with a 30-s fade-in and a 30-s fade-out. They received five stimulation sessions within one week, with a minimum interval of 24 hours between each session. The tDCS sensitivity questionnaire was used to assess blinding validity.

Sham group
Arm Description: The study was sham-controlled, randomized, and double-blind. Participants with HUD were randomly assigned to either the active or sham groups. The DC-STIMULATOR PLUS (neuroConn, Germany) was used to deliver stimulation via saline-soaked sponge electrodes (25 cm², 5×5 cm, 1.5 mA). The stimulation in the sham group was set up as a stimulation cycle of 30s fade-in and 30s fade-out, followed by no current stimulation. They received five stimulation sessions within one week, with a minimum interval of 24 hours between each session. The tDCS sensitivity questionnaire was used to assess blinding validity.
