手机依赖高风险人群筛查量表的编制及性能测试

Psychometric validity and screening cutoff point of the short-form Chinese smartphone dependence questionnaire

目的:编制中文简短手机依赖问卷(SPDQ),为手机依赖的群体筛查和公共卫生人群监测提供工具。方法:采用同组研究设计获得221名大学生4次测量数据。内部一致性信度(Cronbach′α)和重测信度(ICC)系数分析问卷信度,探索性和验证性因子分析确定问卷效度,ROC分析确定判断手机依赖的临界值。结果:SPDQ由7个条目构成,具有较高的内部一致性、重测信度与良好的结构效度和效标效度。问卷包含两因子模型,包括认知/心理依赖和行为依赖。验证性因子分析设定所有题目为依赖表现,4次测量χ^(2)值分别为15.23,11.54,13.60和14.11,P均大于0.05。以简短智能手机依赖指数量表(SPAI-SF)为金标准,确定4/5为SPDQ筛查分界值。结论:本研究编制的SPDQ符合心理测量学标准,可作为手机依赖潜在风险人群的筛查工具。

Objective:The short-form Chinese smartphone dependence questionnaire(SPDQ)was developed and validated and established a cutoff point for screening smartphone dependence in China.Methods:A total of 221 participants completed a four-wave online survey that collected demographic data,general mental health,and responses to the 10-item Smartphone Addiction Inventory(SPAI-SF)and 7-tiem SPDQ.Factor analysis,internal consistency,test-retest reliability,and correlation analysis were conducted to verify the reliability and validity of SPDQ.Results:Confirmatory factor analysis(CFA)revealed that the 7-item SPDQ was selected to represent two-factor construct,including cognitive or mental response to dependence and behavioral response to dependence.For maximal diagnostic accuracy,a cutoff point of 4/5 best-discriminated cases of smartphone dependence as a reference to SPAI-SF.Conclusion:SPDQ demonstrated acceptable construct validity and fair to moderate levels of test reliability.This finding provides a valuable tool in population-based research on smartphone dependence in China.
