骨质疏松症患者运动知识和行为问卷的编制及信效度检验

Development and reliability and validity of the Exercise Knowledge and Behavior Questionnaire for Osteoporosis Patients

目的编制适合我国骨质疏松症患者的运动知识和行为问卷,并检验其信效度。方法以知信行理论为指导构建问卷框架,通过文献回顾、小组讨论、半结构访谈、德尔菲专家函询及预调查形成骨质疏松症患者运动知识和行为问卷初稿。采用便利抽样法,选取2020年6—8月苏州大学附属第一医院收治的120例骨质疏松症患者为研究对象进行问卷调查,检验问卷的信效度。共发放120份问卷,回收有效问卷110份,有效回收率为91.67%(110/120)。结果2轮德尔菲专家函询的专家权威系数分别为0.880、0.900,肯德尔和谐系数分别为0.308、0.332(均P<0.01)。骨质疏松症患者运动知识和行为问卷最终包括知识和行为2个层面,共19个条目,其中知识层面10个条目、行为层面9个条目。探索性因子分析显示,运动知识层面共提取出2个公因子,累积方差贡献率为60.712%;运动行为层面共提取出1个公因子,累积方差贡献率为72.075%。总问卷及各层面的内容效度指数分别为0.925、0.921、0.929,各条目的内容效度指数为0.857~1.000;总问卷及各层面的Cronbach’’sα系数分别为0.935、0.830、0.953;总问卷及各层面的折半信度系数分别为0.979、0.898、0.974;总问卷及各层面的重测信度系数分别为0.878、0.813、0.860。结论骨质疏松症患者运动知识和行为问卷具有较好的信效度,可用于骨质疏松症患者运动知识及行为评估。

Objective To develop the Exercise Knowledge and Behavior Questionnaire for Osteoporosis Patients suitable for China,and to test its reliability and validity.Methods Guided by the theory of knowledge,attitude and practice,a questionnaire framework was constructed,and the first draft of the Exercise Knowledge and Behavior Questionnaire for Osteoporosis Patients was formed through literature review,group discussion,semi-structured interview,Delphi expert consultation and pre-investigation.From June to August 2020,convenience sampling was used to select 120 osteoporosis patients admitted to the First Affiliated Hospital of Soochow University as the research object to conduct a questionnaire survey to test the reliability and validity of the questionnaire.A total of 120 questionnaires were distributed,110 valid questionnaires were recovered,and the valid recovery rate was 91.67%(110/120).Results Among 2 rounds of Delphi expert consultation,the expert authority coefficients were 0.880 and 0.900,respectively,and the Kendall harmony coefficients were 0.308 and 0.332,respectively,with statistically significant differences(P<0.01).The Exercise Knowledge and Behavior Questionnaire for Osteoporosis Patients included two sub-questionnaire of knowledge and behavior,with a total of 19 items,including 10 items in knowledge and 9 items in behavior.Exploratory factor analysis showed that 2 common factors were extracted from the exercise knowledge sub-questionnaire,and the cumulative variance contribution rate was 60.712%.A total of one common factor was extracted for the exercise behavior sub-questionnaire,and the cumulative variance contribution rate was 72.075%.The content validity index of the total questionnaire and each sub-questionnaire were 0.925,0.921,and 0.929,respectively,and the item-level content validity index of was 0.857 to 1.000.The Cronbach'sαcoefficients of the total questionnaire and each sub-questionnaire t were 0.935,0.830,and 0.953,respectively,and the split-half reliability coefficients of the total questionnaire and each sub-questionnaire were 0.979,0.898,and 0.974,respectively,and the test-retest reliability coefficients of the total questionnaire and each sub-questionnaire were 0.878,0.813,0.860,respectively.Conclusions The Exercise Knowledge and Behavior Questionnaire for Osteoporosis Patients has good reliability and validity,and can be used to evaluate exercise knowledge and behavior in patients with osteoporosis.
