摘要
目的本研究旨在初步编制《青少年社交网络成瘾评估量表》,并评价该量表在在校本科学生中的信效度。方法采用方便抽样在2018年3月对上海交通大学医学院在校本科学生进行问卷调查,共回收有效问卷665份。在间隔2个月后对46名受试对象进行量表的重测。采用因子分析、Spearman相关分析、Mann-Whitney U检验等计算量表的结构效度、内容效度和区分效度以评价量表效度,采用内部一致性信度、折半信度和重测信度评价量表的信度,采用ROC分析评价诊断能力及临界值。结果调查对象年龄为(19.39±1.35)岁,男性290名,女性375名。KMO值为0.869,Bartlett球形度检验(P<0.001)表明适合进行因子分析。探索性因子分析结果量表为单维度,可解释总变异的53.02%,条目的因子负荷值为0.424~0.671。验证性因子分析结果表示量表结构效度良好(χ^(2)/df=2.842,GFI=0.957,CFI=0.971,RMSEA=0.076)。量表的S-CVI为0.90,各条目与量表相关系数高于0.64(均P<0.001)。网络成瘾者量表得分明显高于非成瘾者(P<0.001)。量表的内部一致信度为0.880,折半信度0.817,重测信度0.788。AUC面积>0.7(P<0.001)。结论量表于在校本科学生中有良好的信效度。
Objective To develop a social network addiction tendency scale for adolescents and to evaluate the reliability and validity of the scale in undergraduate students.Methods A convenient sampling survey was carried out among the undergraduates in Shanghai Jiao Tong University School of Medicine.A total of 665 valid questionnaires were collected.After the interval of 2 months,46 individuals were retested.Factor analysis,correlation analysis and Mann Whitney U test were used to evaluate the validity of the scale.Internal consistency reliability,half reliability and retest reliability were used to evaluate the reliability of the scale.Area under receiver operating characteristic curve was used to evaluate the predictive power and optimal cut-off value of the scale.Results Of the total patients,290 were males(43.6%)and 375 were females(56.4%)with an average age of(19.39±1.35)years.The Kaiser-Meyer-Olkin value was 0.869.Bartlett's sphericity test(P<0.001)indicated that it was suitable for factor analysis.The results of exploratory factor analysis were single dimension,which could explain 53.02%of the total variation.The factor loading of items ranged from 0.424 to 0.671.The results of confirmatory factor analysis showed that the structure and validity of the scale were good(χ^(2)/df=2.842,GFI=0.957,CFI=0.971,RMSEA=0.076).The S-CVI of the scale was 0.90,the correlation coefficient between each item and the scale was higher than 0.64(all P<0.001)and the score of internet addicts was significantly higher than that of non-addicts(P<0.001).The internal consistent reliability of the scale was 0.880,half reliability 0.817 and retest reliability 0.788.The area under the curve of the scale was over 0.7(P<0.001).Conclusion The social network addiction tendency scale has good reliability and validity in undergraduate students.
