原发性肝癌患者营养不良风险评估量表的研制

Development of risk assessment scale for malnutrition in patients with primary hepatic carcinoma(PHC)

目的制订原发性肝癌患者营养不良风险评估综合量表。方法通过查阅文献、专家咨询及预测试形成暂定量表,对我市三家三级甲等医院就诊的150例原发性肝癌患者进行正式调查,进行量表信度和效度的检验。结果正式量表包含3个维度共10个条目,量表内部Cronbach’sα系数为0. 871,各维度分别为0. 728,0. 685和0. 730;量表重测信度为0. 947,各维度分别为0. 941,0. 921和0. 955。共抽取"近期特征改变""营养供需矛盾"和"特征性体征"3个公因子,贡献率分别为30. 3%,28. 9%和15. 7%,累计贡献率73. 9%。结论原发性肝癌患者营养不良风险评估量表具有较好的信度和效度,可用于我国原发性肝癌患者的营养不良风险筛查。

Objective To develop a comprehensive scale for assessing the risk of malnutrition in patients with primary hepatic carcinoma.Methods To examine the reliability and validity of the scale,150 cases of primary hepatic carcinoma patients from three hospitals of grade 3A were formally investigated through literature reviewing,consulting experts and forming provisional scale.Results The formal scale consisted of 10 items in 3 dimensions.The Cronbach'sαcoefficient of the scale was 0.871,and that of each dimension was 0.728,0.685 and 0.730 respectively.The retest reliability of the scale was 0.947,and that of the dimensions were 0.941,0.921 and 0.955 respectively.A total of three common factors,namely,"change of recent characteristics","contradiction between supply and demand of nutrition"and"characteristic signs",were extracted,which the contribution rates were 30.3%,28.9%and 15.7%respectively,and the cumulative contribution rate was 73.9%.Conclusion The malnutrition risk assessment scale for patients with primary hepatic carcinoma proved to be of good reliability and validity,which could be used for screening malnutrition risk in primary hepatic carcinoma patients at home.
