青少年女性性健康促进量表的构建与信效度研究

Development and assessment of Sexual Health Promotion Scale for adolescent female

目的:依计划行为理论为基础,构建性健康促进量表(SHPS),并检验量表的信度与效度。方法:通过性健康促进量表、青少年性与生殖健康文献分析、深度访谈、以及专家咨询,形成SHPS预实验量表,对183名青少女进行问卷调查,对预实验量表进行条目分析、探索性因子分析归纳维度,形成正式量表。正式问卷调查,采分层集束比例抽样,以388名青少女[平均年龄为(18.15±0.39)岁]为对象,分析及建构量表的信效度。结果:SHPS通过探索性因子分析,由22个条目组成,包括性健康知识、性生理需求、避孕态度、艾滋病认知等4个公因子,累积方差贡献率为67.982%;总体内容效度指数为0.926;总量表的Cronbach’sα系数为0.904,重测信度为0.882;而验证性因子分析(χ2/df=2.562,P<0.001,GFI=0.962,RMSEA=0.048,AGFI=0.950,NFI=0.958,CFI=0.934),具有较好的适配度。结论:青少女性健康促进量表具有较好的信度与效度,为评价国内青少女性与生殖健康现状提供科学依据。

Objectives： To construct the development and assessment of Sexual Health Promotion Scale（SHPS） based on the theory of planned behavior so as to test the reliability and validity. Methods： The SHPS pre-test scale was established through the sexual health promotion scale,the analysis of sexual and reproductive literature of adolescents,the results of in-depth interviews and the expert consultation. A total of 183 adolescents were selected as the subjects of the pre-test scale. The pre-test scale was analyzed by item analysis,and exploratory factor analysis to induce the formal dimension. The proportional sampling on 388 adolescents（ mean age 18. 15 ±0. 39） was done to analyze and construct the reliability and validity of the questionnaire. Results： SHPS was composed of 22 items,including sexual health knowledge,sexual needs,contraceptive attitude and AIDS knowledge.The cumulative variance contribution rate of SHPS was 67. 982%. The total content validity index was 0. 926. The Cronbach＇s alpha coefficient was 0. 904 and the test-retest reliability was 0. 882. The confirmatory factor analysis was（ χ~2/df = 2. 562,P 0. 001,GFI = 0. 962,RMSEA = 0. 048,AGFI = 0. 950,NFI = CFI = 0. 934）,with a good fit measure. Conclusion： The SHPS for adolescent female has good reliability and validity,which can provide a scientific basis for the evaluation of the present situation of teenage female sexual health in China.
