The Relationgship Between Sleep Qulity And Cyber-Loafing:The Mediating Effect Of Ego Depletion

Cyber-loafing is the personal volitional behavior of employees who use the network to carry out activities unrelated to work for personal purposes during working hours,which will bring some negative effects to the organization.Less attention was paid to the physiological factors on cyber-loafing.But sleep was important for individual's physiology and psychology.For employees,sleep quality was easily affected by pressure,which leaded to decrease attention in work,cyber-loafing and other work deviant behaviors.Thus,this study explored the effect of employees'sleep quality on cyber-loafing and explored the influencing mechanism.According to the theory and research of ego-depletion,sleep can influence organizational behavior by influencing the degree of ego-depletion of individuals.Therefore,this study further explored the relationship between sleep quality and cyber-loafing from the perspective of ego-depletion,revealing the role of ego-depletion.Considering that there was no suitable tool to measure the cyber-loafing of employees in China,this study firstly compiled the"Employee Cyber-loafing Questionnaire";Then,through the electronic questionnaire link to extend“Pittsburgh Sleep Quality Index","Self-Regulatory Fatigue Scale"and"Employee Cyber-loafing Questionnaire",to evaluate sleep quality,ego depletion and cyber-loafing,then discusses the differences of demographic variables of the three and the relationships between the three.SPSS 20.0,LISREL 8.7 and MPLUS 7.0 were used to analyze the data.Finally,the main results of this study were as follows.(1)The self-compiled"Employee Cyber-loafing Questionnaire"consisted of three dimensions:"communication","leisure"and"investment",with a cumulative explanation variation of about 65.64,the model fitted well(?~2/df=3.99,GFI=0.96,AGFI=0.93,CFI=0.97,IFI=0.97,RMR=0.037,RMSEA=0.068).The Cronbach's?of the total questionnaire was 0.81 and the Cronbach's?of the three dimensions was0.77,0.78 and 0.75.The whole questionnaire has good reliability and validity,which can be used to measure employees'cyber-loafing behavior.(2)The test of differences in demographic variables of sleep quality,ego-depletion and cyber-loafing showed that:The main effects and interaction effects of gender,age,position and unit nature were not significant in sleep quality.The main effects of gender,position and nature of the unit were not significant in ego-depletion;the main effect of age was significant(F=12.49,p<0.001);the interaction effect of gender,age and unit nature was significant(F=2.85,p=0.037).The main effects of gender,position and unit nature on cyber-loafing were not significant;the main effect of age was significant(F=4.49,p=0.034).(3)The test results of the relationship between sleep quality,ego-depletion and cyber-loafing:In the model of the effect of sleep quality on cyber-loafing,sleep quality had a significant negative predictive effect on cyber-loafing,with an effect value of 0.36(p<0.001);In the mediating effect model of ego-depletion,sleep quality had a significant negative predictive effect on ego-depletion,with an effect value of0.24(p<0.001),and ego-depletion had a significant positive predictive effect on cyber-loafing,with an effect value of 0.56(p<0.001),ego-depletion played a part in mediating the effect of sleep quality on cyber-loafing,the mediating effect value was0.13,accounting for 35.14%of the total effect.
