中老年女性骨健康素养问卷研制及信效度检验

Reliability and validity of the bone health literacy questionnaire for middle-aged and elderly women

目的旨在编制围绝经期前后女性骨健康素养问卷,检验其信效度,为该问卷在中老年女性人群中的推广提供科学依据。方法根据WHO欧洲办事处2012年对健康素养的定义,确定问卷的理论框架;然后借鉴国内外骨健康相关研究、通过两轮专家咨询,初步形成骨健康素养问卷。研究对象为上海市城郊7个区的45~65岁社区女性。信度检验采用克朗巴赫α系数和分半信度,效度检验包括内容效度、区别效度、会聚效度和结构效度。结果经过专家多轮讨论删减后形成40个条目的骨健康素养问卷。研究共纳入447名45~65岁社区女性。问卷的Cronbach'sα为0.763,分半信度为0.793。总问卷与各领域得分之间的相关系数为0.403~0.703,问卷的内容效度较好;问卷的会聚效度与区别效度定标试验成功率分别为57.50%和86.25%;验证性因子分析结果显示,拟合度指数(goodness of fit index,GFI)等指标达到适配标准,结构效度良好。结论中老年女性骨健康素养问卷具有较好的信效度,可作为中老年女性骨健康素养测量和评价的简易工具。

Objective To develop a questionnaire for assessing bone health literacy among perimenopausal and postmenopausal women,then evaluate its reliability and validity,and to provide scientific evidence for the application of the questionnaire in the middle-aged and elderly.Methods A theoretical framework was developed based on the integrated theoretical model of health literacy proposed by Regional Office for Europe of WHO in 2012.Based on the relevant research on bone health at home and abroad,and through two rounds of expert consultation,a bone health literacy questionnaire was formed.The community women aged 45-65 years were investigated in 7 urban and suburban districts of Shanghai.Cronbach’sαand split-half reliability were calculated to evaluate the reliability of bone health literacy questionnaire;content,discriminant,convergent and structural validity were performed to measure the validity of the questionnaire.Results A forty-item bone health literacy questionnaire for perimenopausal and postmenopausal women was finalized through expert meetings.A total of 447 women aged 45-65 years from community were investigated for the evaluation.The overall Cronbach'sαof the bone health literacy questionnaire was 0.763 and the split-half reliability was 0.793.The correlation coefficient of each sub-questionnaire with the total questionnaire was 0.403-0.703.The bone health literacy questionnaire had good content validity,with the success rate of calibration experiment of 57.50%and 86.25%respectively.Confirmatory factor analysis showed that the goodness of fit index(GFI)and other indicators reached the adaptation standard,and the structural validity was good.Conclusion The questionnaire has good reliability and validity,and can be used as a simple tool to measure and evaluate bone health literacy among middle-aged and elderly women.
