Reliability and validity assessment of Daily Stressors Evaluation Scale for Urban Secondary School Students
-
摘要:
目的 编制适用于当代城市中学生、具有良好信效度的压力源评价量表,为研究中学生心理压力及相关因素提供工具。 方法 根据量表编制理论和流程,结合已有的青少年生活事件或压力源量表,形成城市中学生压力源条目池,在上海市2个区的393名中学生中实施预调查,进行项目分析和评价维度确定。再经分层整群抽样选取上海市11个区的2 949名学生进行量表的验证性因子分析。 结果 最终形成28个条目的“城市中学生压力源评价量表”,学业压力、自我身心压力、人际压力和家庭压力4个分维度分别包含8,7,7,6个条目,量表总体的Cronbach α系数为0.94,Guttman分半信度为0.88,重测信度0.68。验证性因子分析显示,近似误差均方根(RMSEA)和标准化残差均方根(SRMR)均 < 0.08,拟合度指标在0.8以上。 结论 编制的“城市中学生压力源评价量表”信效度良好,模型拟合优度理想,适用于城市中学生。 Abstract:Objective To formulate an evaluation scale on daily stressors with good reliability and validity for urban secondary school students, and to provide a tool for psychological stress assessment. Methods Based on steps of instrument development, a pool of items regarding the daily stressors of junior/senior high school students was constructed by combining existing scales of adolescent life events or stressors, and a preliminary survey was conducted for items analysis and dimension evaluation among 393 middle and high school students in 2 districts of Shanghai. Then confirmatory factor analysis of the scale was conducted among 2 949 students collected by stratified cluster sampling from 11 districts in Shanghai. Results The final 28-item daily stressors evaluation scale for urban secondary school students, with an overall Cronbach's alpha coefficient of 0.94, consists of 8, 7, 7, and 6 items for the four dimensions of academic stress, physical and psychological stress, interpersonal stress and family stress, respectively. The Guttman's split-half reliability was 0.88, and the test-retest reliability was 0.68. Total scores of the 28 items reflect general psychological stress level of participants, with higher scores representing higher stress intensity. The confirmatory factor analysis showed that the root mean squared error of approximation (RMSEA) and the standardized root mean square residual (SRMR) were both less than 0.08, while all fit indexes were above 0.8. Conclusion The Daily Stressors Evaluation Scale for Urban Secondary School Students, with good reliability, validity and model goodness of fit, can be applicable for urban secondary school students. -
