肌少症疾病知识量表的编制及信效度检验

Development of disease knowledge scale for sarcopenia and its reliability and validity test

目的:编制肌少症疾病知识量表,并验证其信效度。方法:通过文献回顾、2轮专家咨询及预调查,构建肌少症疾病知识量表初表;于2023年1月—6月选取贵州省4所三级甲等医院304例可疑肌少症病人进行调查,以验证量表信效度,形成肌少症疾病知识量表终表。结果:肌少症疾病知识量表包括病因、临床表现、危害、诊断、治疗5个维度和18个条目;2轮咨询专家权威系数为0.917,0.921,肯德尔协调系数为0.219,0.297(均P<0.001);量表水平的内容效度指数为0.970,Cronbach′sα系数为0.935。结论:编制的肌少症疾病知识量表具有良好的信效度、科学性及实用性,可作为肌少症病人疾病知识水平的评估工具。

Objective:To establish the disease knowledge scale for sarcopenia and test its reliability and validity.Methods:The initial scale was developed through a comprehensive literature review,followed by two rounds of Delphi letter inquiry and a pre-survey.From January to June,2023,a total of 304 patients with possible sarcopenia from four tertiary Grade A hospitals in Guizhou province were surveyed to construct a formal scale.Results:The disease knowledge scale for sarcopenia included 5 dimensions of etiology,clinical manifestation,harm,diagnosis and treatment,and 18 items.The authority coefficient were 0.917,0.921.Kendall′s W were 0.219,0.297(all P<0.001).The S-CVI was 0.970,Cronbach′sαcoefficient was 0.935.Conclusion:The constructed disease knowledge scale for sarcopenia has good reliability,validity,scientificity and practicability,and it can be used as a tool to evaluate the disease knowledge level of patients with sarcopenia.
