摘　　要：目的编制青少年手机多任务行为评定问卷并评价信度和结构效度,为开展相关流行病学研究提供评价工具。方法通过文献综述、专家资讯、小组讨论自行编制青少年手机多任务行为评定问卷,确定手机活动与非媒体活动多任务、手机活动与其他媒体活动多任务以及手机功能使用多任务3个维度,初步纳入27个条目。于2021年10—12月选取辽宁、山西、河南、上海、重庆、深圳、云南7个地区,采取多阶段整群抽样方法抽取5566名在校大学生进行问卷调查,结合条目分析、因子分析、信度评价等多种统计学方法对问卷的条目进行筛选和信度、效度评价。结果青少年手机多任务行为评定问卷最终包含3个维度,共计26个条目;方差累计贡献率为59.63%,内部一致性检验得出问卷的Cronbachα系数为0.944,各维度的Cronbachα系数为0.838~0.928;问卷的分半系数为0.849,各维度的分半系数为0.781~0.874。验证性因子分析结果显示,问卷的近似均方根残差、比较拟合指数、塔克—刘易斯指数分别为0.068,0.901,0.891,具有较好的拟合优度。Pearson相关性分析结果显示问卷效标效度较好(r=0.206~0.351,P值均<0.01)。结论青少年手机多任务行为评定问卷符合心理统计学评价标准,可作为评价青少年手机多任务行为的评估工具。Objective To develop the Assessment of Smartphone Multitasking for Adolescents(ASMA)and evaluate its reliabil-ity and construct validity,so that to provide an evaluation tool for relevant epidemiological studies.Methods Based on literature review,expert-based judgement,and group discussion,the self-administered ASMA identified 3 dimensions named smartphone ac-tivities and non-media activities multitasking,smartphone activities and other media activities multitasking,and smartphone func-tional use multitasking,which initially included 27 items.From October to December 2021,5566 college students were selected from 7 regions,including Liaoning,Shanxi,Henan,Shanghai,Chongqing,Shenzhen,and Yunnan by multi-stage cluster sampling method,and item analysis,factor analysis,and reliability evaluation were used to screen items and evaluate reliability and validity.Results The final version of AMSA contained 3 dimensions covering 26 items.The variance cumulative contribution rate was 59.63%.The internal consistency test showed that Cronbach's alpha coefficient for the questionnaire was 0.944,and ranged from 0.838 to 0.928 for each dimension.The split-half coefficient of the questionnaire was 0.849 and ranging from 0.781 to 0.874 for each dimension.The results of confirmatory factor analysis showed that the root mean square error of approximation(RMSEA),compara-tive fit index(CFI),and Tucker-Lewis index(TLI)of the questionnaire were 0.068,0.901,and 0.891,respectively,which had which had a good fiting degree.The results of Pearson correlation analysis showed that the criterion validity of the questionnaire was good(r=0.206-0.351,P<0.01).Conclusion The ASMA is consistent with the evaluation standard of psychometrics and can be used as an assessment tool to evaluate smartphone multitasking behaviors in adolescents.
