Results: The occurrence rates of internet addiction tendency and IAD in intervention group after the intervention were 4. 63% and 3. 24%,respectively,compared with before intervention,the differences of which were statistical significance( P 0. 01). Compared with before intervention,the students with time online less than 2 h and more than 4 h in intervention group after the intervention were significantly increased and decreased,respectively( P 0. 01), the differences in two groups were statistical significance( P 0. 01). The scores of SCL-90 and all factors and negative dealing measures in intervention group after intervention were significantly lowered than those in intervention group before intervention and control group( P 0. 01),the score of positive dealing measures in intervention group after intervention was significantly higher than that in control group( P 0. 01). Conclusions: The comprehensive intervention model guided by the theory of health promotion and based on college for undergraduate IAD can effectively reduce the occurrence rates of internet addiction tendency and IAD,improve the internet addiction symptoms and cognition of using internet,increase the psychological health level and improve the negative dealing measures in college students.
