摘要目的:探讨大学生家庭功能与错失焦虑之间的关系及归属需要受挫与自我控制在其中的链式中介作用。方法:采用家庭功能量表、归属需要满足与受挫量表、自我控制量表和错失焦虑量表，对广东省五所高校409名大学生进行问卷调查。运用SPSS 26.0进行共同方法偏差检验、Pearson相关分析和分层回归分析，采用PROCESS 3.5宏程序进行中介效应检验。结果:(1)家庭功能、归属需要受挫、自我控制和错失焦虑的总分分别为(166.01±16.08)分、(9.39±2.51)分、(37.88±6.27)分、(56.38±6.59)分。(2)家庭功能与归属需要受挫呈显著负相关( r ＝－0.43， P<0.01)，与自我控制呈显著正相关( r ＝0.43， P<0.01)，与错失焦虑呈显著负相关( r ＝－0.39， P<0.01)；归属需要受挫与自我控制呈显著负相关( r ＝－0.37， P<0.01)，与错失焦虑呈显著正相关( r ＝0.38， P<0.01)；自我控制与错失焦虑呈显著负相关( r ＝－0.42， P<0.01)。(3)家庭功能对错失焦虑的直接效应值为－0.17(95% CI ＝－0.27~－0.07)，家庭功能通过三条路径间接影响错失焦虑，归属需要受挫的单独中介作用效应值为－0.09(95% CI ＝－0.14~－0.05)，自我控制的单独中介作用效应值为－0.09(95% CI ＝－0.14~－0.05)，归属需要受挫和自我控制的链式中介作用效应值为－0.03(95% CI ＝－0.04~－0.01)。 结论:家庭功能不仅可以直接影响错失焦虑，也可以通过归属需要受挫和自我控制的链式中介作用间接影响错失焦虑。

abstractsObjective:To explore the chain mediating effect of relatedness need-frustration and self-control between family function and fear of missing out (FoMO) in college students.Methods:A sample of 409 college students from five universities in Guangdong province was surveyed with family assessment device (FAD), relatedness need-satisfaction and frustration scale, self-control scale (SCS), and fear of missing out scale.Common method bias test, Pearson correlation analysis and Hierarchical regression analysis were conducted to analyze the data using SPSS 26.0 software, and PROCESS V3.5 macro program was used to test the mediating effect.Results:(1) The total scores of family function, relatedness need-frustration, self-control and FoMO were(166.01±16.08), (9.39±2.51), (37.88±6.27)and(56.38±6.59), respectively. (2) Family function was negatively correlated with relatedness need-frustration ( r =-0.43, P<0.01), positively correlated with self-control( r =0.43, P<0.01), and negatively correlated with FoMO ( r =-0.39, P<0.01). Relatedness need-frustration was negatively correlated with self-control ( r =-0.37, P<0.01), and positively correlated with FoMO( r =0.38, P<0.01). Self-control was negatively correlated with FoMO( r =-0.42, P<0.01). (3)The direct effect of family function on FoMO was -0.17(95% CI =-0.27--0.07). Family function affected FoMO through three paths. The separate mediation effect of relatedness need-frustration was -0.09(95% CI =-0.14--0.05), the separate mediation effect of self-control was -0.09(95% CI =-0.14--0.05), and the chain mediation effect of relatedness need-frustration and self-control was -0.03(95% CI =-0.04--0.01). Conclusion:Family function not only directly affects FoMO, but also indirectly affects FoMO through relatedness need-frustration and self-control.
