Abstract：
BACKGROUND: In the present cross-sectional study, we investigated whether reasons for smartphone use are similar to those of social media use. Also, we explored links between reasons of smartphone use and mental health variables (problematic smartphone use, FOMO, depression symptoms, and life satisfaction) in Germany during the COVID-19 lockdown period.
METHODS: Overall, 571 smartphone users (Mage = 31.60, SDage = 12.73) provided their reasons for smartphone use. The reasons were assigned to six categories by an inductive qualitative content analysis.
RESULTS: Five of six reasons were similar to those of social media described by previous research. \"Search for social interaction\" goes along with less problematic smartphone use and depression symptoms and more life satisfaction. \"Search for positive feelings\" is associated with lower life satisfaction. More depressed people, those with problematic smartphone use tendencies, higher FOMO, and lower life satisfaction tend to \"escape from negative emotions.\"
CONCLUSIONS: Our results help to understand the relationships between reasons for smartphone use and mental health variables.

摘要：
背景：在本横断面研究中，我们调查了使用智能手机的原因是否与使用社交媒体的原因相似。此外，我们探讨了智能手机使用原因与心理健康变量之间的联系(有问题的智能手机使用，FOMO,抑郁症状,和生活满意度)在COVID-19封锁期间在德国。
方法：总的来说，571位智能手机用户（Mage=31.60，SDage=12.73）提供了使用智能手机的理由。通过归纳定性内容分析将原因分为六个类别。
结果：六个原因中有五个与先前研究描述的社交媒体相似。“搜索社交互动”伴随着更少的问题智能手机使用和抑郁症状以及更多的生活满意度。“寻找积极的感受”与较低的生活满意度有关。更多抑郁的人，那些有问题的智能手机使用倾向，更高的FOMO,较低的生活满意度往往会“摆脱负面情绪”。
结论：我们的研究结果有助于理解使用智能手机的原因与心理健康变量之间的关系。
