项目介绍

本研究由安赫莱斯大学基金会的田源在安赫莱斯大学基金会的艾米丽-萨米恩托（Emily Sarmiento）的指导下进行。该研究调查了中国大学生使用社交媒体与健康结果之间的相关性，重点关注学习成绩、情绪健康和睡眠质量。该项目是研究生院毕业论文的一部分，旨在解决人们日益关注的数字互动对精神和情绪的影响问题。

Purpose and conduct of the study

The primary goal of the study is to examine the impact of social media usage on the mental health and academic outcomes of college students. The research explores social media's correlation with anxiety, depression, and sleep irregularities. The insights will serve as a basis for potential policy interventions and support for healthier digital habits among students, thus addressing a critical gap in understanding social media’s broader impact on young adults' lives.

研究目的和实施

本研究的主要目的是探讨社交媒体的使用对大学生心理健康和学习成绩的影响。研究将探讨社交媒体与焦虑、抑郁和睡眠不规律的相关性。这些见解将为潜在的政策干预和支持学生养成更健康的数字习惯提供依据，从而弥补在了解社交媒体对年轻人生活的更广泛影响方面存在的重要空白。

Participant’s information (nature and extent of involvement)

Participants, a sample of 400 university students aged 18-30 from Hebei Province, China, will complete structured, quantitative questionnaires measuring their social media usage, academic performance, sleep quality, and emotional well-being. The involvement spans approximately one academic term, with each session expected to take around 30-45 minutes, depending on the length of the questionnaire. Participants' self-reported data will be collected using validated scales, ensuring comprehensive and reliable measures of the key variables.

参与者信息（参与的性质和程度）

参与者是来自中国河北省的 400 名 18-30 岁大学生，他们将完成结构化的定量问卷，测量他们的社交媒体使用情况、学习成绩、睡眠质量和情绪健康状况。参与时间跨度约为一个学期，根据问卷长度的不同，每次参与时间预计约为 30-45 分钟。将使用经过验证的量表收集参与者的自我报告数据，确保对关键变量进行全面、可靠的测量。

Risk and inconveniences

Participants may experience minor discomfort when reflecting on their personal social media habits, potentially leading to anxiety or stress. The ICF includes a section outlining these potential risks, as well as available support. Risks are minimized by allowing participants to skip sensitive questions and providing access to counseling resources if needed. Participation remains entirely voluntary, and individuals can withdraw at any time without any negative impact on their academic standing.

风险和不便

在反思个人社交媒体习惯时，参与者可能会感到轻微不适，从而可能导致焦虑或压力。国际功能、残疾和健康分类》中有一节概述了这些潜在的风险以及可提供的支持。我们允许参与者跳过敏感问题，并在需要时提供咨询资源，从而将风险降至最低。参与完全出于自愿，个人可以随时退出，不会对其学业产生任何负面影响。

Confidentiality and data management

All collected data will be securely stored, with personal identifiers removed and encrypted to ensure confidentiality. The data management plan adheres to the Data Privacy Law, implementing anonymization protocols. Data will be retained for a specified period and securely deleted following the study’s completion.The duration of the data was from the beginning of obtaining ethical permission to the completion of the study. Participants will have the right to request access to a summary of their own data, subject to privacy policies.

保密和数据管理

所有收集到的数据都将安全存储，去除个人识别信息并进行加密，以确保保密性。数据管理计划遵守《数据隐私法》，执行匿名化协议。数据将在规定期限内保留，并在研究完成后安全删除。在遵守隐私政策的前提下，参与者有权要求查阅自己的数据摘要。

Access to the results of the study

Participants will receive a summary of the study’s findings upon completion and publication. They may also request access to their individual data, in line with confidentiality and data access policies. This transparency helps participants understand how their input contributed to the research outcomes.

获取研究结果

研究完成并发表后，参与者将收到一份研究结果摘要。根据保密和数据访问政策，他们也可以要求访问他们的个人数据。这种透明度有助于参与者了解他们的投入是如何促成研究成果的。

Sampling Method

The study employs a stratified random sampling method, dividing participants by grade level to ensure a representative sample across different demographics. Academic performance data will be self-reported by participants to respect their privacy, avoiding direct requests for grades from university records.

抽样方法

本研究采用分层随机抽样法，将参与者按年级划分，以确保不同人口统计学特征的样本具有代表性。学业成绩数据将由参与者自我报告，以尊重他们的隐私，避免直接从大学记录中获取成绩。

Measurement of Social Media Use

Social media usage is measured through self-reported frequency, duration, and context via a standardized questionnaire. This approach ensures a detailed understanding of participants' engagement across various social media platforms.

社交媒体使用情况的测量

社交媒体的使用情况是通过一份标准化的调查问卷，以自我报告的频率、持续时间和环境来衡量的。这种方法可确保详细了解参与者在各种社交媒体平台上的参与情况。

Expenses and Compensation

No direct compensation or expenses are outlined, as the study does not involve interventions that would necessitate participant reimbursement. However, incidental costs like transportation may be covered.

费用和补偿

由于本研究不涉及需要向参与者报销的干预措施，因此没有列出直接补偿或费用。不过，交通费等杂费可以报销。

Handling of Withdrawal Data

If a participant chooses to withdraw, their collected data will be excluded from the analysis, and any information gathered will be securely deleted to maintain the integrity of the research and respect participant autonomy.

退出数据的处理

如果参与者选择退出，其收集的数据将被排除在分析之外，收集到的任何信息都将被安全删除，以保持研究的完整性并尊重参与者的自主权。

Clarification on Sponsorship

The study is self-funded, with no external sponsorship or financial influence affecting the research process or outcomes. This independence ensures an unbiased analysis and reporting of the results.

赞助说明

这项研究是自筹资金进行的，研究过程或结果不受任何外部赞助或财务影响。这种独立性确保了分析和报告结果的公正性。
