青少年健康相关行为自我效能量表的编制

摘要

Objective Base on comprehensive theories,the adolescent health-related behavior self-efficacy scale were developed,and the reliability and validity were tested.Methods The basic framework of the scale was formed by literature analysis,questionnaire survey and professionals' interview.Totally 1032 valid questionnaires were collected from adolescent population in four provinces in China.Correlation analysis and exploratory factor analysis were used for item selection.Reliability and validity tests were administered for the final scale.Results This scale was composed of 4 dimensions and 52 test items involving 6 kinds self-efficacy of health-related behaviors.The reliability and validity of the scale were satisfactory,with a cumulative contribution rate of 71.76％,and a Cronbach's α coefficients,split-half reliability and test-retest coefficients of 0.910,0.903 and 0.839 respectively.Confirmatory factor analysis shows the scale had good fit index:x2/df=2.673,RMSEA ＜0.041,GFI=0.938,AGFI=0.925,CFI=0.949,TLI=0.942,IFI=0.949.The result of the difference of gender,region and grade were in accord with the current situation of adolescents.Conclusion The adolescent health-related behavior self-efficacy scale is an effective measurement tool.%目的 基于相关理论研究,初步编制青少年健康相关行为自我效能量表,并检验其信效度.方法 在文献资料分析、访谈和问卷调查及专家论证的基础上形成量表,从4个省份收集青少年有效问卷1032份,运用相关系数分析、探索性因子分析等方法筛选条目,对量表测试版进行信、效度检验.结果 编制的量表涉及6类健康相关行为自我效能,共4个维度,52个条目,方差累积贡献率为71.76％;总量表Cronbach'sα系数为0.910,分半信度为0.903,重测信度为0.839;验证因子分析显示数据拟合良好,x2/df=2.673、RMSEA =0.041、GFI =0.938、AGFI =0.925、CFI =0.949、TLI =0.942、IFI=0.949;以性别、地域、年级等为分组变量的区分度结果显示符合青少年期各种行为现况.结论 青少年健康相关行为自我效能量表是有效的测量工具.
