压疮愈合计分量表的汉化及其信效度研究

Reliability and validity of the Chinese version of the Pressure Ulcer Scale for Healing

目的：压疮愈合计分量表是用于量化评价压疮护理效果的工具。文中对汉化版压疮愈合计分量表信度和效度进行检验，为评价压疮护理效果提供有效可信的工具。方法采用Brislin翻译模型对原量表进行汉化，经专家组及预试验调适形成量表最终版，并选取126例Ⅱ-Ⅳ期压疮患者进行信度和效度检验。采用项目分析、内容效度、结构效度、反应度、评定者间信度、重测信度对量表的信效度进行分析。结果项目分析结果显示，各条目得分与量表总分相关系数0．616～0．963（ P＜0．01），上27％高分组（n＝35）各条目得分均高于下27％低分组（n＝36）（P＜0．01）。量表总的内容效度系数为0．965，总分和各条目之间的结构效度系数0．750～0．954（P＜0．01）。各条目之间的相关系数0．666～0．826（P＜0．01）。治疗后7 d和21 d总分和各条目计分结果差异有统计学意义（P＜0．01）。量表总Cronbach′s系数为0．823，各条目Cronbach′s系数分别为0．770、0．791和0．868。评定者间信度均＞0．85，各条目重测信度系数为0．826、0．885和0．958（P＜0．01）。结论量表中文版有良好的效度和信度，适合用于中国压疮患者的效果评价。

Objective Pressure Ulcer Scale for Healing （ PUSH） was published in 1998 by National Pressure Ulcer Advisory Panel （ NPUAP） as a tool to evaluate the effects of pressure ulcer care.This study aimed to verify the reliability and validity of the Chi-nese version of PUSH in order to provide an efficient and reliable tool for evaluating the effects of pressure ulcer care. Methods Using the Brislin translation model, we translated the English version of PUSH into Chinese and finalized the Chinese version through modifica-tion by an advisory panel, pretests, and verification of its reliability and validity in the care of 126 cases of stage-Ⅱ-Ⅳpressure ulcers. We analyzed the reliability and validity of the scale based on its item scores, content validity, construct validity, Cronbach′s αcoeffi-cient, and test-retest reliability. Results The correlation coefficient value of the total and individual item scores was 0.616-0.963 （P0.85 and the test-retest reliabili-ty coefficients of individual items were 0.826, 0.885, and 0.958, re-spectively （ P〈0.01） . Conclusion The Chinese version of PUSH, with its high validity and reliability, can be used to evaluate interven-tion effectiveness of Chinese patients with pressure ulcers.
