目的编制藏族大学生性心理健康问卷,为评估藏族大学生性心理健康状况提供测评工具。方法在参考胡珍教授的《新世纪大学生性文明调查问卷》及有关文献资料的基础上,结合专家意见,经过预调查确定初测问卷;使用初测问卷进行调查,获得有效样本230份,使用探索性因子分析筛选题项,经主成分分析和方差最大正交旋转,保留特征值>1、且题项个数≥3的公因子,将因子载荷<0.4、共同度<0.2或公因子包含题项个数<3的题项删除,最终形成正式问卷;使用正式问卷进行调查,获得有效样本481份,采用克朗巴哈系数法和分半信度系数法考核问卷的内在信度,使用验证性因子分析考核问卷的结构效度。结果经过4次探索性因子分析,将初测问卷性心理、性观念(态度)部分的39个题项删减为34个题项,形成7因子模型。总量表和7个因子维度的Cronbach’sα系数分别为0.920、0.898、0.812、0.844、0.787、0.684、0.703、0.608,Spearman-Brown系数分别为0.763、0.867、0.742、0.838、0.746、0.822、0.677、0.564,说明问卷具有良好的内在信度;进行验证性因子分析所采用的结构方程模型与原始数据的拟合程度较好,拟合指标:卡方自由度比值(χ2/df)=3.736、残差均方根(RMR)=0.081、渐进残差均方根(RMSEA)=0.076、拟合优度指数(GFI)=0.805、调整拟合优度指数(AGFI)=0.770、规范拟合指数(NFI)=0.774、相对拟合指数(RFI)=0.749、增值拟合指数(IFI)=0.824、非规范拟合指数(NNFI)=0.803、比较拟合指数(CFI)=0.823、简约调整拟合优度指数(PGFI)=0.684、简约调整规范拟合指数(PNFI)=0.698、简约调整比较拟合指数(PCFI)=0.742,说明问卷具有良好的结构效度。结论藏族大学生性心理健康问卷具有良好的信度和效度。
Objective To prepare a questionnaire on sexual mental health of Tibetan college students and provide a tool to evaluate the sexual mental health of Tibetan college students. Methods Based on the “Questionnaire on Sexual Civilization of College Students in the New Century” by Professor Hu Zhen and relevant documents and materials, combined with the expert opinion, the preliminary test questionnaire was determined through the preliminary investigation. The preliminary test questionnaire was used to investigate and obtain 230 valid samples, Exploratory factor analysis screening items, principal component analysis and variance maximum orthogonal rotation, retain the eigenvalues> 1, and the number of items ≥ 3 common factor, the factor load <0.4, commonality <0.2 or common factor contains The number of items <3 items deleted, and finally form a formal questionnaire; using a formal questionnaire survey to obtain a valid sample of 481 copies, using the Cronbach’s coefficient method and semi-reliability factor coefficient method to assess the internal reliability of the questionnaire, the use of verification Structural validity of the questionnaire on sexual factor analysis. Results After 4 exploratory factor analyzes, 39 items in the first part of questionnaire psychology and sexual attitudes (attitude) were deleted to 34 items to form a 7-factor model. The Cronbach’sα coefficients of the total scale and the seven factor dimensions were 0.920,0.898,0.812,0.844,0.787,0.684,0.703,0.608, Spearman-Brown coefficients were 0.763,0.867,0.742,0.838,0.746,0.822,0.677 , 0.564, indicating that the questionnaire has a good intrinsic reliability. The structure equation model used in the confirmatory factor analysis is better fitted to the original data. The fitting index: the ratio of chi square degree of freedom (χ2 / df) = 3.736, (RMSEA) = 0.076, GFI = 0.805, adjusted goodness of fit index (AGFI) = 0.770, normative fit index (NFI) = 0.774, RFI = 0.749, IFI = 0.824, NNFI = 0.803, CFI = 0.823, PGFI = 0.684, PNFI = 0.698, and PCFI = 0.742, indicating that the questionnaire has good structural validity. Conclusion The questionnaire of sexual mental health of Tibetan college students has good reliability and validity.
