ABSTRACT

ObjectiveTo understand the status and relationship between social support level and Internet addiction among left-behind middle school students， so as to provide references for the targeted intervention and risk reduction of Internet addiction. MethodsStratified cluster random sampling method was used to recruit 3 532 middle school students from six middle schools in a county of Southeast Chongqing， including 1 945 （55.07%） left-behind students and 1 587 （44.93%） non-left behind students. All the selected students were assessed using self-designed general situation questionnaire， Diagnostic Scale of Internet Addiction for Middle School Students （DSIA-MSS） and Adolescent Social Support Rating Scale （ASSRS）， then the trend test was performed on relationships of social support to Internet addiction. Results① The detection rate of Internet addiction in the left behind group was higher than that in the non-left behind group （22.98% vs. 16.13%， χ2=25.732， P<0.01）. ② ASSRS score in the left behind group was lower than that in the non-left behind group ［（66.81±15.92） vs. （68.19±16.18）， t=2.544， P=0.011］. ③ Among three different living states of students （non-left behind， one-parent working outside， both-parents working outside）， the detection rate of Internet addiction demonstrated significant differences among students with different social support levels （χ2=35.220， 37.662， 31.434， P<0.01）. ④ A "dose-effect" relationship of social support to Internet addiction was found， indicating that students with higher social support levels suffered a lower risk of Internet addiction （P<0.01）. ConclusionLeft-behind middle school students develop a prominent problem of Internet addiction， which is closely related to their social support level， and the two aspects display a negative "dose-effect" relationship.
