摘要目的 开发认知障碍疼痛评估量表(PACIE)并检验其效度和信度.方法 参考国外的疼痛评估工具,编制认知障碍疼痛评估量表.分别请疼痛、麻醉、护理方面5位专家进行内容效度的评定并修改,由经过统一培训的评定员对认知障碍老年人的疼痛程度进行评估,并临床检验量表的效度和信度.结果 PACIE包括8个条目,内容效度指数为0.978,经因子分析得到2个公因子,累积解释方差的69.008%.2个公因子归为疼痛客观表现因子和疼痛主观表现因子.PACIE总分与NRS得分具有高度相关性,能正确区分认知障碍疼痛患者与认知障碍无疼痛患者.PACIE评定者间组内相关系数为0.954(95%CI为0.812～0.989),量表总分的Cronbach'α为0.851.结论 PACIE具有良好的信度和效度,指标客观,简单有效,可用于认知障碍老年人的疼痛评估.

abstractsObjective To develop pain assessment scale for cognifively impaired elderly (PACIE) and to test its reliabihty and validity. Methods Based on the foreign related pain assessment tools, the pain as-sessment scale for cognitively impaired elderly was developed. Five experts specialized in pain, anaesthesia and nursing were invited to evaluate the content validity of the pain assessment instrument and made modification. Reliability and validity of the pain assessment instruments was evaluated. Results PACIE had 8 items, index of content validity (CVI) of PACIE was 0.978, factor analysis demonstrated that two factors soluted in PACIE, that cumulative explained 69.008% of the total variability, the two factors were named pain objective factor and pain subjective factor. PACIE and NRS were significantly correlated, it could identify pain and painlessness patients overtly that demonstrate the discriminate validity was fine. Adequate levels of inter-rater reliability of PACIE was achieved between two raters with the intra-class correlation coefficient as 0.954 (95%CI=0.812～ 0.989). Satisfactory test-retest reliability was achieved with the Cronbach'α ot as 0.851. Conclusions The pain assessment scale for cognitively impaired elderly (PAC1E) has satisfactory validity and reliability, is suit-able for assessing the pain indentity of cognitively impaired elderly.
