中文版疼痛评估软件在老年术后患者中应用的信、效度分析

Analysis of reliability and validity of Chinese version software for pain assessment among elderly patients after surgery

目的测评中文版疼痛评估软件的信效度，为老年术后患者疼痛评估提供工具。方法对疼痛评估软件内容严格遵循＂翻译—回译—文化调适—预实验＂程序进行修订、翻译最终形成中文版疼痛评估软件，2015年6—7月选取98例择期手术的老年患者进行疼痛评分检验其信效度。结果疼痛评估软件经主成分分析共提取出静息、床上活动、进食、深呼吸、咳嗽5个公因子共20个条目，累计贡献率为80.184%，各维度与常用面部表情评分表（FPS）及数字评分表（NRS）的相关系数为0.586~0.933，总Cronbach′s α系数为0.912。结论疼痛评估软件性能良好，具有很高的信度和较高的效度，用于评估老年患者术后疼痛效果可靠。

ObjectiveTo evaluate the reliability and validity of Chinese version software for pain assessment, so as to provide an instrument for postoperative pain assessment in elderly.MethodsWe strictly revised and translated the software for pain assessment into Chinese version according to the program of ＂translation-back translation-cultural adaptation-pre experiment＂. From June to July 2015, 98 elderly patients who would undergo surgery were selected as the research object, and they were evaluated by pain score to test the reliability and validity.ResultsPain assessment software extracted a total of 20 items of 5 common factors including tranquillization, bed activity, eating, deep breathing and cough by principal component analysis （PCA） , which could explain 80.184% of total variances. The Correlated coefficients between each dimension and faces pain scale （FPS） and numerical rating scale （NRS） were between 0.586-0.933. The Cronbach′s α coefficient was 0.912 for the total scale.ConclusionsThe pain assessment software has good performance, high reliability and high validity. It can be used to evaluate the reliability of postoperative pain in elderly patients.
