概括

过度使用智能手机,定义为每周超过63小时的屏幕时间或400次解锁,在大学生中显著增加了非自杀性自伤 (NSSI) 风险. 客观措施证实了这一关联,强调了智能手机使用作为一个关键的干预目标.

科学领域:

心理健康研究心理健康研究
数字健康数字健康
青少年心理学青少年心理学

背景情况:

智能手机使用与心理健康之间的关系,特别是非自杀性自伤 (NSSI),正在积极调查中.
以往依赖于自我报告数据的研究可能在测量实际智能手机参与度时缺乏准确性.
对智能手机使用的客观测量对于准确评估智能手机对心理健康的影响至关重要.

研究的目的:

为了调查客观测量的智能手机使用和NSSI在中国大学生的大队伍之间的关联.
确定与增加NSSI风险相关的智能手机屏幕时间和解锁频率的具体门.

主要方法:

一项涉及中国6所大学16668名大学生的多中心,横截面研究.
通过使用"太华自伤目录"进行NSSI评估,对在过去一个月报告任何事件的参与者进行分类.
客观的智能手机使用数据 (屏幕时间,解锁) 通过智能手机记录收集.

主要成果:

共有3.8%的参与者报告了NSSI.
与较低使用组相比,在学生每周屏幕时间≥63小时 (OR 1.63) 和≥400次解锁/周 (OR 1.53) 的情况下,观察到NSSI的几率明显更高.
限制性立方线分析证实了智能手机使用指标升高和NSSI风险之间的剂量反应关系.

结论:

高水平的智能手机使用 (≥63小时的屏幕时间或每周≥400次解锁) 被确定为大学生中NSSI的重要风险因素.
这些发现强调了在制定NSSI干预措施时考虑智能手机使用模式的重要性.
对数字行为的客观测量为心理健康风险因素提供了有价值的见解.

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Self-Discrepancy Theory

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
