研究设计:

Study design:

Parallel 

研究目的:

1.从认知加工角度探索复吸机制,构建“负性情绪 → 注意偏向 → 复吸倾向”的路径机制,并检验工作记忆容量在该路径中的调节作用; 2.评估认知训练(工作记忆训练联合注意偏向矫正)干预对成瘾者负性情绪、注意偏向、工作记忆容量及渴求的改善作用。  

Objectives of Study:

1.To elucidate the cognitive mechanisms underlying relapse by establishing a pathway from negative affect to relapse propensity mediated by attention bias, and to test whether working memory capacity moderates this pathway; 2.To assess the therapeutic effects of a cognitive training intervention—integrating working memory training and attention bias modification—on negative affect, attentional processing biases, working memory capacity, and drug craving in methamphetamine use disorder.

组别:

对照组

样本量:

Group:

control group

Sample size:

干预措施:

对照组接受戒毒所的常规戒毒治疗(TAU),包括但不限于:戒毒知识讲座、团体教育活动、常规运动训练、日常行为管理等。所有内容均由戒毒所按照其标准化流程实施,不包含额外的计算机化训练或个体认知训练任务。

干预措施代码:

TAU

Intervention:

Participants in the control group will receive the standard rehabilitation program routinely implemented in the compulsory drug rehabilitation center. This includes drug education lectures, group-based educational activities, routine physical exercise, and daily behavioral management. No additional computer-based or cognitive training procedures will be provided.

Intervention group

Sample size:

干预措施:

干预组在常规戒毒治疗基础上,额外接受为期4周的计算机化认知训练。本训练完全基于计算机界面,无侵入性、无药物成分,对参与者无生理风险。训练包括两部分:(1)工作记忆训练(WMT):采用 N-back 等任务(2)基于情绪线索的注意偏向矫正(ABM):采用点探测范式引导注意从负性情绪刺激中脱离。两部分均约25分钟,连续进行,期间休息十分钟,每次共计约一小时,一周两次,持续4周。(详见计划书)

干预措施代码:

INT

Intervention:

The intervention group will receive an additional 4-week computerized cognitive training program on top of the standard rehabilitation treatment. The training is entirely computer-based, non-invasive, medication-free, and poses no physical risk to participants. It consists of two components: (1) Working Memory Training (WMT), using N-back–type tasks; and (2) Emotion-based Attention Bias Modification (ABM), using a dot-probe paradigm to guide attention away from negative emotional stimuli. Each component lasts approximately 25 minutes and is administered consecutively with a 10-minute break in between, resulting in a total session duration of about one hour. Training is conducted twice per week for 4 weeks. (See study protocol for details.)
