Objective: To investigate the effect of psychological intervention on the prevention of internet addiction in junior high school students of Jinan.
Methods: A total number of 888 junior high school students in Jinan City were assessed by Internet Addiction Disorder Diagnostic Scale (IADDS). 57 cases students were diagnosed with internet addiction according to the scores of IADDS, while the rest 831 students were required to fill the self-designed general questionnaire, such as demographic questionnaire and Symptom Checklist 90 (SCL-90) and randomly divided into the intervention and the control groups. The psychological intervention was given in 4 states during two years, one stage in each semester, and there were 4 classes in each stage.
Results: In the intervention group, the IADDS and SCL-90 scores were significantly lower compared with those in the control students at different time points of T2 and T3 (all Ps<0.01). In the intervention group, the different factors of SCL-90 were decreased after each intervention (all Ps<0.01). These results showed that the intervention has positive effects on the mental health of students. The positive rate of internet addiction screened by IADDS in the intervention group was considerably lower compared with that in the controls at T2 and T3 time points (all P<0.05).
Conclusion: Longitudinal prospective and preventive psychological intervention can effectively improve the mental health of junior middle school students of Jinan city and reduce the incidence of internet addiction.
