FLACC量表用于学龄前儿童术后疼痛评估的信效度评价

Evaluation of reliability and validity of FLACC scale in postoperative pain assessment of preschool children

目的验证儿童疼痛行为(FLACC)量表的信度和效度。方法选取小儿外科接受手术治疗的学龄前儿童178例,术后使用FLACC量表进行疼痛评估,分析该量表的信度和效度。结果量表内部一致性信度Cronbach′sα系数为0.853,重测信度为0.706-0.866,评定者间信度为0.966-0.993(P<0.01);因子分析产生2个公因子,共能解释总体方差的66.695%,量表各条目得分与总量表得分的相关系数为0.682-0.867(P<0.01),效标效度为0.653-0.882(P<0.01)。结论 FLACC量表具有较好的稳定性和可靠性,可作为我国学龄前儿童术后疼痛评估的有效工具,从而为临床镇痛药物和技术的使用提供可靠依据。

Objective To validate the reliability and validity of the pain behavior scale for children（FLACC scale）. Methods The postoperative pain was assessed using FLACC scale in 178 preschool children underwent surgery. The reliability and validity of FLACC scale in evaluating postoperative pain were validated. Results The scale internal consistency reliability Cronbach＇s a coefficient was 0. 853, test-retest reliability was 0. 706-0. 866, inter rater reliability was 0. 966-0. 993 （P〈0. 01）. Factor analysis generated two common factors, which were able to explain the overall variance of 66. 695%, the coefficient of correlation scale item and total scores was 0. 682-0. 867 （P〈0. 01）, and the criterion validity was 0. 653-0. 882 （P〈0. 01）. Conclusion FLACC scale has good reliability and stability and can be taken as an effective tool in evaluating postoperative pain in preschool children, which provides a reliable basis for postoperative analgesia.
