摘　　要：目的探讨贵州省中等职业技术学校学生(简称中职生)自我控制与睡眠质量之间的关系以及反刍思维和情绪调节的中介作用。方法采取简单随机整群抽样方法选取贵州省中职生1178名为调查对象,现场调查方式收集中职生的一般资料(年龄、性别、年级、生源地及独生子女等),采用匹茨堡睡眠质量指数(PSQI)、自我控制问卷(SCS)、反刍思维问卷(RRS-CV)及情绪调节问卷分别评价中职生的睡眠质量、自我控制水平、反刍思维能力及认知重评策略(CR)、表达抑制策略(ES);采用Person相关分析来探讨自我控制、反刍思维能力、CR、ES与睡眠质量的相关关系,采用多元线性分析SCS对PSQI的预测作用,采用Bootstrap方法分析SCS、RRS-CV、ES与PSQI的链式中介作用。结果贵州中职生SCS与PSQI(r=-0.571,P<0.01)、RRS-CV(r=-0.556,P<0.01)及ES(r=-0.386,P<0.01)呈负相关;贵州中职生PSQI与RRS-CV(r=0.534,P<0.01)和ES(r=0.408,P<0.01)呈正相关,RRS-CV与ES呈正相关(r=0.492,P<0.01);SCS对贵州中职生PSQI的直接预测效应有统计学意义(β=-0.102,P<0.01,95%CI为-0.116~-0.116);RRS-CV和ES在SCS与PSQI间的3条中介路径均有统计学意义(P<0.05,95%CI为-0.050~-0.029、-0.010~-0.003及-0.012~-0.005)。结论自我控制水平对贵州省中职生睡眠质量具有直接正向预测作用,且存在自我控制、反刍思维、ES及睡眠质量的链式中介效应。Objective To investigate the relationship between self-control and sleep quality among secondary vocational school students(SVSS)in Guizhou province and the mediating role of rumination and emotion regulation.Methods A simple random cluster sampling method was used to select 1178 SVSS from Guizhou province as survey subjects.On-site surveys were performed to collect general information(age,gender,grade,place of origin and whether they were only children,etc.).Pittsburgh sleep quality index(PSQI),self-control scale(SCS),rumination responses scale Chinese version(RRS-CV),and emotion regulation questionnaire were used to assess sleep quality,self-control level,rumination ability,cognitive reappraisal(CR),and expressive suppression(ES)strategy,respectively.Pearson correlation analysis was used to explore the associations of self-control,rumination ability,CR and ES with sleep quality.Multiple linear regression analysis was conducted to analyze the predictive role of SCS for PSQI.Bootstrap methods were used to analyze the chain mediation effects of SCS,RRS-CV,and ES on PSQI.Results SCS of Guizhou SVSS was negatively correlated with PSQI(r=-0.571,P<0.01),RRS-CV(r=-0.556,P<0.01),and ES(r=-0.386,P<0.01).PSQI of Guizhou SVSS was positively correlated with RRS-CV(r=0.534,P<0.01)and ES(r=0.408,P<0.01),and RRS-CV was positively correlated with ES(r=0.492,P<0.01).The direct predictive effect of SCS on PSQI of Guizhou SVSS was statistically significant(β=-0.102,P<0.01,95%CI was from-0.116 to-0.116).The three mediating paths between SCS and PSQI via RRS-CV and ES were all statistically significant(P<0.05,95%CI was form-0.050 to-0.029,-0.010 to-0.003,and-0.012 to-0.005).Conclusion Self-control level has a directly,positive predictive effect on sleep quality among SVSS in Guizhou province,and there is a chain mediation effect involving self-control,rumination,ES and sleep quality.
