随着科技的进步，电子产品对人们的生活的影响日益加深。科技一方面在帮助我们，一方面也无所不用其极地获取着我们的注意力。于是，开始出现了一些手机使用明显过度的人群。对手机的过度使用不仅妨碍到他们的日常生活、学业工作，也对他们的身体和心理健康产生了不小的危害。心理学的研究发现，个体的自我控制能力对手机依赖有影响，但就自我控制与手机依赖之间机制的研究比较匮乏。

本研究探究自我控制与手机依赖的关系，另外检验和探讨一套自主开发的提升自我控制能力课程的效果，以及自我控制课程干预降低手机依赖的表现和机制。

研究一为课程开发与迭代，主要通过访谈法（N = 10) 收集自我控制课程的效果与反馈。有效访谈材料为9份，进行主题分析后最终整理成了119个条目，初步验证了课程的效果，并收集到很多对课程迭代有价值的反馈意见。

研究二使用自我控制课程进行干预。在随机控制设计实验中（N = 230) ，干预组相比于等待组，自我控制水平有显著的提升，而手机依赖、孤独感、一般自我效能感的改善并未达到统计显著水平。在干预组中，自我控制和手机依赖、孤独感以及一般自我效能感都呈现出高度相关性。路径分析中也发现自我控制分别对孤独感、一般自我效能感、手机依赖有影响，尽管孤独感和一般自我效能感的中介作用并未得到支持。

本研究通过随机控制的干预研究验证了课程对自我控制能力提升的有效性。研究也进一步探索了自我控制、孤独感、一般自我效能感与手机依赖的关联，为进一步探索通过自我控制改善手机依赖的机制提供了参考。

With the advancement of technology, electronic products have increasingly influenced people's lives. While technology has helped us, it has also aggressively competed for our attention. Consequently, there is a growing population of individuals who use their phones excessively, which not only disrupts their daily lives and academic/work performance but also poses significant risks to their physical and mental health. Psychological research has found that an individual's self-control has an impact on mobile phone dependence, but research on the mechanism between self-control and mobile phone dependence is relatively scarce.

This study aims to explore the relationship between self-control and mobile phone dependence, as well as test and examine the effectiveness of a self-developed self-control training program in reducing mobile phone dependence and its mechanisms.

Study 1 focused on course development and iteration. The effects and feedback of the self-control training program were collected through interview methods (N = 10), with 9 valid interviews subjected to thematic analysis, resulting in 119 entries that preliminarily confirmed the effectiveness of the course and provided valuable feedback for course iteration.

Study 2 used a self-control intervention course for intervention, and in a randomized controlled design experiment (N = 230), the intervention group showed a significant improvement in self-control level compared to the waitlist group, while improvements in mobile phone dependence, loneliness, and general self-efficacy did not reach statistical significance. In the intervention group, self-control, mobile phone dependence, loneliness, and general self-efficacy exhibited significant correlations. Path analysis also found that self-control had an effect on loneliness, general self-efficacy, and mobile phone dependence, although the mediating effects of loneliness and general self-efficacy were not supported.

This study verified the effectiveness of the course in improving self-control ability through a randomized controlled intervention study. The study also further explored the relationship between self-control, loneliness, general self-efficacy, and mobile phone dependence, providing a reference for further exploration of the mechanism of improving mobile phone dependence through self-control.
