【摘要】 目的 了解问题性社交网站使用和抑郁之间的关联，探讨错失焦虑、成人依恋模式在问题性社交网站使用和抑郁之间的多重中介作用。方法 在新冠疫情流行期以来，于2020年6月～2020年7月，使用问题性社交网站使用量表错失焦虑量表、成人依恋量表、抑郁自评量表对广西南宁和百色市两所医学院校的911名医学生进行网络问卷调查，评估问题性社交网站使用对抑郁情绪的影响。结果 农村家庭的医学生问题性社交网站使用、抑郁总分高于城市家庭（P<0.05）。多重中介效应分析表明，医学生问题性社交网站使用通过错失焦虑和依恋焦虑对抑郁有正向的直接预测作用（β=0.187,P<0.001），问题性社交网站使用正向预测错失焦虑和依恋焦虑（β=0.662,β=0.597,P<0.001），错失焦虑负向预测抑郁（β=-0.338,P<0.001），依恋焦虑正向预测抑郁（β=0.415,P<0.001），错失焦虑和依恋焦虑在问题性社交网站使用与抑郁之间起单独中介效应。结论 农村家庭的医学生在新冠疫情流行期的问题性社交网站使用、抑郁情绪高，问题性社交网站使用还可通过错失焦虑和依恋焦虑影响医学生的抑郁情绪，错失焦虑和依恋焦虑在问题性社交网站使用和抑郁情绪之间起中介作用。更多还原

【Abstract】 Objective To investigate the association between problematic social networking site use and depression, and to explore the mediating effects of fear of missing out and adult attachment pattern on problematic social networking site use and depression. Methods From June to July 2020,a network questionnaire survey was conducted among 911 medical students from two medical colleges in Nanning and Baise, Guangxi, using problematic social networks usage, fear of missing out measurement scale, adult attachment scale, and self-rating depression scale. To assess the effects of problematic social networking site use on depressive mood. Results The use of problematic social networking sites and the total score of depression of medical students in rural families were higher than those in urban families(P<0.05). Multiple mediating effect analysis showed that problematic social networking site use of medical students directly predicted depression through fear of missing out and attachment anxiety(β=0.187, P<0.001),problematic social networking site use positively predicted fear of missing out and attachment anxiety(β=0.662, β=0.597, P<0.001), fear of missing out negatively predicted depression(β=-0.338, P<0.001), attachment anxiety positively predicted depression(β=0.415, P<0.001), fear of missing out and attachment anxiety had a separate mediating effect between problematic social networking site use and depression. Conclusion Medical students from rural families have higher use of problematic social networking sites and higher depressive mood during the epidemic period. Problematic social networking site use can also affect the depressive mood of medical students through fear of missing out and attachment anxiety, which play a mediating role between problematic social networking site use and depressive mood.更多还原
