腰腿痛患者报告结局量表的应用分析

摘要

目的:检验腰腿痛患者报告结局量表的信度、效度及反应度.方法:2010年8月至2012年1月,纳入住院腰椎间盘突出症及腰椎管狭窄症患者患者200例,男93例,女107例；年龄22～65岁,平均50.3岁；腰椎间盘突出症144例,腰椎管狭窄症56例 应用腰腿痛患者报告结局量表对患者进行测评,并对量表进行信度、效度、反应度分析.结果:39例病情无变化患者两次评分无显著性差异(P＞0.05),且有显著相关性(r＞0.9)；该量表同Oswestry功能障碍指数问卷(ODI)对患者评分结果具有显著相关性(r＞0.8)；该量表总体克朗巴赫α系数为0.931,总体Guttman折半系数为0.912;该量表KMO统计量为0.919,Bartlett球形检验卡方值l 882.975(P＜0.01),因子分析方法提取特征根值＞1的3个公因子,累计贡献率为64.364％;43例病情有好转患者两次评分结果分别为34.80±9.00和28.77±8.73,两者差异有统计学意义(P＜0.01).结论:腰腿痛患者报告结局量表有较好的信度、效度及反应度,可作为腰腿痛患者临床疗效的评价工具.%Objective:To explore the reliability,validity and reaction degree of patient reported outcome scale for low back and leg pain. Methods:Two hundreds inpatients were analyzed between August 2010 and January 2012,including 93 males and 107 females with an average age of 50.3 years old ranging from 22 to 65 years. There were 144 cases of lumbar disc herniation and 56 of lumber spinal stenosis. All patients were tested by the patient reported outcome scale for low back and leg pain,and then analyzed the reliability,validity and reaction degree of the scale. Results:There was no statistical significence difference (P>0.05) and significant correlation (r>0.9) in scores of two times in patients with no change in illness. Measurement result of the scale had significant correlation (r>0.9) with Oswestry disability index (ODI). The total Cronbach's Alpha of the instrument was 0.931, the total split-half reliability was 0.912. The KMO value was 0.919, Bartlett test value was 1882.975 (P<0.001) .factor analysis resulted in 3 factors with eigenvalue >1 which contributed to 64.364%. Scores of two times of 43 cases who felt better were 34.80±9.00 and 28.77±8.73,respectively,with stasitical significance (P<0.01). Conclusion:The scale has a good reliability, validity and reaction degree, which can be applied for the therapeutic evaluation of low back and leg pain.
