研究目的:

本研究拟探讨基于小脑靶向的高精度经颅直流电刺激(HD-tDCS)对精神分裂症患者动机性阴性症状的改善作用。若证实干预有效,将深入解析其作用机制:在心理层面,重点考察奖赏加工系统的功能改变;在神经层面,系统研究小脑-奖赏环路的功能激活模式及网络连接特征。  

Objectives of Study:

This project aims to examine whether high-definition transcranial direct current stimulation (HD-tDCS) targeting the cerebellum can alleviate motivational negative symptoms in individuals with schizophrenia. If such improvement is observed, the project will further investigate whether the underlying psychological mechanism involves alterations in reward processing, and whether the neural mechanism is associated with changes in functional activation and connectivity within the cerebellum and the reward circuitry.

随机方法(请说明由何人用什么方法产生随机序列):

由干预实施医生产生,根据入组的顺序将所有参与者编号为1-60号,使用计算机软件excel生成与编号一一对应的随机数字序列,然后根据随机数字序列的大小将编号排序,前30名(对应编号的受试者)纳入真刺激组,后30名纳入伪刺激组。

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

The treating physician assigned sequential IDs (1–60) to participants upon enrollment. Using Excel, a random number sequence was generated for each ID. Participants were then sorted by these random numbers, with the first 30 assigned to the real stimulation group and the remaining 30 to the sham stimulation group.

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:

数据采集中,通过纸质CRF收集被试的基本信息、临床症状量表得分、自评问卷、IQ等信息。通过Psychopy和E-prime软件收集奖赏相关行为表现。通过3T Philips Ingenia收集脑结构与脑功能成像。 数据存储中,保留原始纸质问卷,同时录入excel电子表格。行为数据与核磁数据同样保留备份原始数据。

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

In data collection, basic information about participants, scores from clinical symptom scales, self-report questionnaires, and IQ were collected using paper Case Record Forms (CRFs). Reward-related behavioral data was recorded using Psychopy and E-prime software. Brain structural and functional imaging data were collected using a 3T Philips Ingenia MRI scanner. For data storage, the original paper questionnaires will be retained while the data will also be entered into Excel spreadsheets. Backups of the original data will be kept for both behavioral data and MRI data.
