青少年网络成瘾预测问卷初步编制及信效度检验

Development and Psychometric Analysis of Internet Addiction Predict Test for Adolescents

目的:编制简单有效的青少年网络成瘾预测问卷(IAPT)。方法:对2620名中学生(男1319,女1301,年龄15.1±1.7岁)用网络成瘾测验(IAT)分成网络成瘾及成瘾倾向组(IA)和对照组,从长处与困难问卷(SDQ),艾森克人格问卷儿童版(EPQ)、儿童焦虑性情绪障碍筛查表(SCARED)、自尊量表(SES)、青少年时间管理倾向量表(ATMD)中找出两组得分有显著差异(P<0.01)的项目构成条目库,一致化、合并、删减形成问卷初稿。抽取1363名中学生(男709,女654,年龄13.7±1.0岁)施测,对问卷初稿进一步精简并信效度检验。结果:IAPT五因子模型(神经质、焦虑、时间管理、自尊、行为问题)共56条目,有较好的结构效度(df/n=2.5,NFI=0.84,NNFI=0.88,RMSEA=0.046);Cronbachα系数0.72,间隔6个月重测信度0.61;问卷及各因子得分与预测目标的相关系数0.35-0.60,P<0.001;问卷及各因子在I-AT组与对照组得分有显著差异(t=6.8-13.2,P<0.001;Cohen’sd=0.51-1.15>0.5);IAPT划界分39分时,Youden指数出现最大值0.62,此时真阳性率(TPF)0.83,假阳性率(FPF)0.21,正确率0.80。结论:IAPT有较好的信效度,可用于青少年网络成瘾预测。

Objective： To develop Internet Addiction Predict Test （IAPT） for Adolescents. Methods： 2620 middle school students（1319 boys, 1301 girls, mean of age 15.1±1.7 years） were divided into IA group and CONTROL group according to Internet Addiction Test. Items were collected with significant difference （P〈0.01） and higher discrimination （D〉 0.20） between the two groups from SDQ, EPQ, SCARED, SES and ATMD, and reconciled, screened and encoded, and then a draft of IAPT was formed. IAPT draft and IAT were used to investigate 1363 students（709 boys, 604 girls, mean of age 13.69＋0.95 years） to verify the IAPT＇s reliability and validity. Results： The model of IAPT （ 5 factors and 56 items） was clear and stable and its construct validity was receptihle （df/n=2.5, NFI=0.84, NNFI=0.88 RMSEA=0.046）. Its reliability （Cronhach ct=0.72,and re-test reliability=0.61,P〈0.001） was satisfactory. The correlation coefficients between predictable object （IAT） and IAPT and its factors were 0.35-0.60. The retest reliability after six months was 0.61, P〈0.001. The difference of IAPT and its factors between IA and CONTROL group was significant （t=6.8-13.2,P〈0.001 ;Cohen＇s d= 0.51-1.15〉0.5）. When the score of IAPT was 39, the Youden index was the biggest（0.62）, the true positive fraction（TPF） was 0.83 and false positive fraction（FPF） was 0.21, and correct frequency was 0.80. Conclusion： The IAPT has good reliability and validity. And it could he used to predict adolescents＇ Internet addiction.
