目的 编制适用于喉癌行喉部分切除术患者报告功能结局量表并验证其信效度,为准确评估患者功能状态及制定有效的康复训练方案提供依据.方法 根据患者报告结局量表研制指南,经查阅文献、半结构式访谈、专家函询和患者认知测试形成量表初稿;便利选取4所三级甲等医院的喉癌行喉部分切除术患者410例进行调查,对量表进行项目分析和信效度检验.结果 正式量表包含吞咽功能、发音功能及呼吸功能3个维度共21个条目.3个公因子累积方差贡献率69.794%;验证性因子模型拟合良好.量表的平均内容效度指数为0.980,各维度与量表总体间的相关系数为0.655~0.840.总量表的Cronbach's α系数为0.928,折半信度0.734,重测信度为0.846.结论 喉部分切除术患者报告功能结局量表信效度良好,可作为喉部分切除术患者功能结局的评估工具.
Objective To develop and validate the reliability and validity of the Patient-reported Functional Outcomes Scale for Pa-tients after Partial Laryngectomy,and to provide a reference for accurately assessing the functional status of patients and formula-ting effective rehabilitation training programs.Methods According to the guidelines of Patient-reported Outcomes Measures,a pre-test scale was formed through literature review,semi-structured interviews,expert consultation and patient cognitive interviews.A total of 410 patients after partial laryngectomy for laryngeal cancer from 4 general hospitals were conveniently selected for survey.Survey data were used for item analysis and to test reliability and validity of the scale.Results The formal scale contained 3 dimen-sions(swallowing function,voice function,and respiratory function)and 21 items,and the cumulative variance contribution rate of the 3 common factors was 69.794%.Confirmatory factor analysis showed that the fit indexes were good.The content validity index of the whole scale was 0.980,and the correlation coefficients between each dimension and the total score was 0.655-0.840.The Cronbach's α coefficient was 0.928,the split-half reliability coefficient was 0.734,and the test-retest reliability coefficient was 0.846.Conclusion The scale has good reliability and validity.It can be used as a valid tool to assess the functional outcome for pa-tients after partial laryngectomy.
