大学生日周期类型与网络成瘾的关系

Relationship between circadian typology and internet addiction in college students

目的调查大学生的网络成瘾及日周期类型状况,探索日周期类型与大学生网络成瘾的关系。方法抽取3572名大学生,将大学一年级和大学三年级学生分别作为低年级组和高年级组,采用清晨夜晚型量表评定日周期类型,网络成瘾量表评定网络成瘾,进行自填式问卷调查。结果大学生网络成瘾平均得分为(38.46±11.84)分,网络成瘾率为41.7%。高年级和低年级大学生在日周期类型分布和网络成瘾得分上均差异有统计学意义(χ2=10.51,P<0.01;t=5.90,P<0.01),高年级组大学生的夜晚型比例和网络成瘾得分[33.0%,(39.66±12.71)分]都高于低年级组[28.3%,(37.32±10.82)分]。在低年级组中,夜晚型的大学生网络成瘾得分[(40.79±11.33)分]高于中间型[(36.54±10.27)分]和清晨型[(32.27±9.66)分],差异有统计学意义(F=51.81,P<0.01)。在高年级组中,夜晚型的大学生网络成瘾得分[(42.90±13.02)分]同样都高于中间型[(38.61±12.19)分]和清晨型[(34.06±11.92)分],差异有统计学意义(F=37.80,P<0.01)。协方差分析扣除性别、年龄、年级、和父母学历的影响后,仍发现不同日周期类型的大学生网络成瘾得分差异有统计学意义(F=93.53,P<0.01)。多元有序Logistic回归的结果显示,年级(高年级相对于低年级,OR=1.42,P<0.01)和日周期类型(夜晚型相对于清晨型,OR=3.82,P<0.01;中间型相对于清晨型,OR=1.97,P<0.01)是影响网络成瘾的独立因素。结论大学生网络成瘾程度较高,在高低年级之间有差异,高年级学生网络成瘾程度高于低年级学生。大学生的日周期类型越偏向夜晚型,其网络成瘾程度越高。

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 intermediate 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 parents’ educational level by analysis of covariance,IAT scores were still statistically different in circadian typology(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 influencing 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.
