多囊卵巢综合征患者健康促进生活方式量表的编制及信效度检验

The development of a health-promoting lifestyle scale for patients with polycystic ovary syndrome and the test of its reliability and validity

目的编制多囊卵巢综合征(polycystic ovary syndrome,PCOS)患者健康促进生活方式量表,检验其信效度,并初步应用该量表。方法基于Pender健康促进模型,通过文献研究、半结构式访谈、小组讨论构建量表条目池;经过德尔菲专家函询、预调查,形成初始量表。于2022年4月—10月,选取在南京市某三级甲等医院就诊的PCOS患者作为调查对象,第1次纳入316例、第2次纳入358例PCOS患者进行量表项目分析及信效度检验;2022年11月—2023年2月,初步应用量表调查294例PCOS患者健康促进生活方式水平现状。结果PCOS患者健康促进生活方式量表包括5个维度,33个条目。量表水平的内容效度指数为0.942;探索性因子分析提取5个公因子,累计方差贡献率为62.399%。验证性因子分析显示,模型拟合良好。总量表的Cronbach’sα系数为0.930、折半信度为0.842,重测信度为0.888。初步应用结果显示,PCOS患者健康促进生活方式量表总分为(96.925±14.273)分,处于中等水平。结论PCOS患者健康促进生活方式量表信效度较好,可作为医护人员评估PCOS患者健康促进生活方式水平的工具,并能帮助护理人员快速识别患者健康促进生活方式水平等级及各维度情况,以制订个体化的精准健康管理方案。

Objective To develop a health-promoting lifestyle scale for women with polycystic ovary syndrome(PCOS),and to test its reliability and validity,and preliminarily apply it.Methods Based on the Pender health promotion model,the item pool of the scale was constructed through literature research,semi-structured interviews and group discussions.After 2 rounds of Delphi expert consultation and pre-survey,the initial scale was formed.From April to July 2022,316 patients with PCOS in the health management center,reproductive medicine center and endocrinology department of a tertiary hospital in Nanjing were selected for item analysis,exploratory factor analysis and reliability test,respectively.From August to October 2022,358 PCOS patients were selected for confirmatory factor analysis.From November 2022 to February 2013,294 PCOS patients were selected,and the scale was used to investigate the status of health-promoting lifestyle in PCOS patients.Results The health-promoting lifestyle scale for PCOS patients included 5 dimensions and 33 items.The total content validity index of the scale was 0.942,and the content validity index of each item was 0.810-1.000.5 common factors were extracted by 2 exploratory factor analyses,and the cumulative variance contribution rate was 62.399%.Confirmatory factor analysis showed that the model fit was good.The Cronbach’sαcoefficient of the total scale was 0.930;the split-half reliability was 0.842;the test-retest reliability was 0.888.The preliminary application results showed that the total score of health-promoting lifestyle in PCOS patients was(96.925±14.273),and the average score of items was(2.937±0.433),which was at a medium level.Conclusion The health-promoting lifestyle scale for PCOS patients has good reliability and validity,which can be used as a tool for medical staff to assess the level of health-promoting lifestyle of PCOS patients,and can help nurses to quickly identify the level and dimensions of health-promoting lifestyle of patients,so as to formulate individualized precise health management plans.
