Abstract:
Objective To investigate status of internet addiction and circadian typology in college students and to explore the relationship between circadian typology and internet addiction. Methods A total of 3 572 college students including freshmen and juniors was enrolled in the study. Circadian typology and internet addiction were assessed by morningness-eveningness questionnaire(MEQ) and internet addiction test (IAT) respectively. All questionnaires were self-reported. Results The score of IAT was (38. 46±11. 84) points and incidence of internet addiction was 41. 7%. Freshmen and juniors were significantly different in distribution of circadian typology and IAT scores(χ2=10. 51,P<0. 05; t=5. 90,P<0. 01). Proportion of the evening type and scores of IAT of juniors(33. 0%,(39. 66±12. 71)points) were both higher than those of freshmen(28. 3%,(37. 32±10. 82)points). For freshmen,IAT scores of evening type students((40. 79± 11. 33)points) was higher than those of intermediate type students((36. 54±10. 27)points) and morning type students((32. 27±9. 66)points),and the differences were statistically significant(F=51. 81,P<0. 01). For juniors,IAT scores of evening type students((42. 90±13. 02)points) was higher than those of intermedi-ate type students((38. 61±12. 19)points) and morning type students((34. 06±11. 92)points),and the differences were statistically significant(F=37. 80,P<0. 01). After adjusting for gender,age,grade and par-ents’ educational level by analysis of covariance,IAT scores were still statistically different in circadian ty-pology(F=93. 53,P<0. 01). Results from ordinal logistic regression showed that grade(juniors compared to freshman,OR=1. 42,P<0. 01) and circadian typology (evening type compared to morning type,OR=3. 82,P<0. 01; intermediate type compared to morning type,OR=1. 97,P<0. 01) were independent factors influen- cing internet addiction. Conclusion Internet addiction of college students is at a high level and different in grades. Compared with junior students,senior students are at a higher level of internet addiction. College students with evening type are more likely to be internet addicted.
