Study design:

Parallel 

研究目的:

本研究拟通过随机平行对照设计,探讨taVNS干预对成瘾者奖赏加工的影响及其神经机制。研究将收集行为学数据、问卷测量和脑电/脑成像指标,以分析干预是否能调节奖赏相关脑区活动、内感受加工水平及渴求水平,为物质使用障碍的干预提供神经科学依据。  

Objectives of Study:

This study aims to investigate the effects of taVNS intervention on reward processing in individuals with substance use disorder and its underlying neural mechanisms using a randomized parallel-controlled design. Behavioral data, questionnaire measures, and EEG/fMRI indicators will be collected to analyze whether the intervention can modulate activity in reward-related brain regions, interoceptive processing, and craving levels, providing a neuroscientific basis for interventions in substance use disorders.

随机方法(请说明由何人用什么方法产生随机序列):

采用计算机生成的区组随机(随机区组大小为4与6交替、顺序保密),并按“物质类型(黄皮/非黄皮)× 成瘾严重程度(中/重度)”进行分层随机,以提高组间基线均衡性。随机序列由独立统计人员使用预先设定的随机种子生成并加密保存。

Randomization Procedure (please state who generates the random number sequence and by what method):

Computer-generated permuted block randomization with random block sizes of 4 and 6. Stratified randomization by substance type (crude heroin vs non-crude) and addiction severity (moderate vs severe) to enhance baseline balance. The random list is created by an independent statistician using a pre-specified seed and stored in encrypted form.

盲法:

采用双盲(受试者与结局评估者盲)。操作者使用外观一致的电极与标准化语句,sham 组刺激参数设置为无生理效应的感知阈下模式;评估者与数据分析者不接触分配信息。

Blinding:

Double-blind (participants and outcome assessors). Identical electrodes and standardized scripts are used; sham parameters are set below physiological effectiveness. Assessors and data analysts are kept masked to allocation.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据采集 行为学数据:通过计算机化任务(如奖赏加工任务、反应抑制任务)采集反应时、正确率等指标。 问卷测量:采用标准化量表(如渴求量表、内感受相关量表),由被试独立填写或在研究人员指导下完成。 生理与神经数据:使用脑电(EEG)和心电(ECG)记录与奖赏加工相关的神经电生理。 数据记录方式:所有数据均通过研究专用电脑或设备采集,自动生成电子文件,并立即进行匿名化处理(以编码代替姓名和身份信息) 数据管理 匿名化与编码:每位被试均分配唯一编号,所有电子数据和纸质问卷均仅标注编号,不含个人身份信息。 存储方式: 电子数据存储在加密硬盘和研究团队专用服务器中,需密码和双重身份验证方可访问。 纸质文件(如知情同意书)单独存放于上锁的文件柜中,仅限项目负责人查阅。 数据备份:电子数据每周进行一次备份,存储于独立的安全硬盘,防止意外丢失。 访问权限:仅限项目负责人及经过培训并签署保密协议的研究人员访问数据。 保存期限:所有数据将保存 5–10 年,用于科研分析与学术发表;到期后将按伦理要求彻底销毁。 质量控制 所有数据录入后将进行双人核查,确保数据完整、无误。 定期进行数据清理和一致性检查,保证科学性和可重复性。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data Collection Behavioral Data: Collected through computerized tasks (e.g., reward processing tasks, response inhibition tasks), including measures such as reaction time and accuracy. Questionnaires: Standardized scales (e.g., craving scales, interoception-related questionnaires) will be administered, completed independently by participants or under the guidance of research staff. Physiological Data: Electrocardiography (ECG) and electroencephalography (EEG) will be recorded to capture autonomic and neurophysiological responses related to reward processing. Recording Method: All data will be collected via dedicated research computers or devices, automatically generating electronic files. Data will be anonymized immediately by replacing personal identifiers with participant codes. Data Management Anonymization and Coding: Each participant will be assigned a unique code. All electronic data and paper-based questionnaires will be labeled with this code only, without personal identifiers. Storage: Electronic data will be stored on encrypted hard drives and project-specific secure servers, accessible only with password protection and two-factor authentication. Paper documents (e.g., informed consent forms) will be stored separately in locked cabinets, accessible only to the principal investigator. Data Backup: Electronic data will be backed up weekly and stored on independent secure hard drives to prevent accidental loss. Access Control: Only the principal investigator and trained research staff who have signed confidentiality agreements will have access to the data. Retention Period: All data will be retained for 5–10 years for research analysis and academic publication. After this period, data will be permanently destroyed in accordance with ethical guidelines. Quality Control Double-checking of all entered data will be conducted to ensure accuracy and completeness. Regular data cleaning and consistency checks will be performed to ensure scientific rigor and reproducibility.
