|
Target disease: |
Adolescents aged between 12 and 19 who have had suicidal ideation or attempts within the past month are considered to be at high risk of suicide. The main conditions involved include the core symptoms of major depressive disorder: (1) Depressed mood: Feeling sad, empty, or hopeless for most of the day, nearly every day, or being observed by others (e.g., crying). (2) Loss of interest or pleasure |

研究目的: |
本研究旨在结合临床心理学量表问卷测评和自主研发的可穿戴手环的多模态生理 信号记录,同时还引入了机器学习方法,利用改进的平衡随机森林算法对与自杀风险 相关的特征因素进行重要性分析,从模型性能层面寻找与自杀风险相关性较大的特 征,同时进一步发展了核稀疏表示方法,并通过多特征融合策略,建立了即时自适应 的自杀行为预测模型,为降低青少年自杀风险提供了有效的理论方法,进而服务于临床。 |

Objectives of Study: |
This study aims to integrate clinical psychological scale questionnaire assessments with multimodal physiological signal recordings from a self-developed wearable wristband. Additionally, machine learning methods are introduced. An improved balanced random forest algorithm is employed to analyze the importance of features related to suicide risk. By examining the model performance, features with a higher correlation to suicide risk are identified. Furthermore, the nuclear sparse representation method is further developed. A real-time adaptive suicide behavior prediction model is established through a multi-feature fusion strategy. This study provides an effective theoretical approach to reduce the suicide risk among adolescents and serves clinical applications. |

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: |
本研究所用数据主要采取三种采集方式:(1) 基线期心理量表数据通过在线平台收集,后续导出所有参试者的填写内容;(2) 生态瞬时评估期间的问卷数据通过“问卷星”采集并导出;(3) 可穿戴手环采集生理指标数据。以上所述所有数据将由研究人员整理汇总并标注每位参试者的数据缺失情况。 本研究的病例报告表 (Case Report Form, CRF) 是按照研究方案的相关内容设计的,用以收集、记录和保存每一名参试者在实验过程中的数据。在实验中既可帮助研究人员完整、准确地记录研究数据,又有利于后续的数据管理和统计分析。CRF的填写研究者必须根据原始资料信息准确、及时、完整、规范地填写。CRF数据的修改必须遵照标准操作程序,保留修改痕迹。 数据接收过程应有相应文件记录,以确认数据来源和是否接收。数据录入流程必须明确该实验的数据录入要求。使用的数据录入流程包括:双人双份录入, 带手工复查的单人录入,和直接采用电子数据采集方式。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The data used in this study were collected through three main methods: (1) Baseline psychological scale data were collected via an online platform, and the responses of all participants were subsequently exported; (2) Questionnaire data during the ecological momentary assessment were collected and exported using "Wenjuanxing"; (3) Physiological data were collected using wearable wristbands. All the data mentioned above will be organized, summarized, and annotated by the researchers to indicate any missing data for each participant. The Case Report Form (CRF) of this study was designed in accordance with the relevant content of the study protocol to collect, record, and preserve the data of each participant during the experimental process. The CRF not only helps researchers to record study data accurately and completely but also facilitates subsequent data management and statistical analysis. Researchers must fill in the CRF accurately, promptly, completely, and in accordance with standard procedures based on the original data. Any modifications to the CRF data must follow standard operating procedures and retain evidence of the changes. The data reception process should be documented to confirm the source of the data and whether it has been received. The data entry process must clearly define the data entry requirements for this experiment. The data entry procedures used include: double data entry by two individuals, single entry with manual review, and direct use of electronic data capture methods. |
