简体中文版脊柱侧凸研究会22项问卷量表的信度与效度评价

Reliability and validity of simplified Chinese version of the Scoliosis Research Society-22 (SRS-22) questionnaire

目的:评价脊柱侧凸研究学会22项问卷表(SRS-22)简体中文版的信度和效度。方法:将简体中文版的SRS-22及相对公认的SF-36量表寄给42例青少年特发性脊柱侧凸术后患者。38例患者(91%)寄回了第1份调查表。这些患者(男7例,女31例)的年龄为(17.8±3.1)岁。38例患者中的35例(92%)寄回了第2份调查表。用Cronbach’sα评价量表信度,组内相关系数评价重测信度。通过因子分析评价量表的结构效度。同期效度通过与SF-36各维度的比较获得,评价指标为Pearson’s相关系数(r)。结果:在4个维度(功能/活动度、疼痛、自我形象/外观、精神健康)的Cronbach’sα系数都大于0.7,治疗满意度维度的Cronbach’sα系数0.44。5个维度的组内相关系数分别为0.94,0.86,0.77,0.74,0.84,显示了良好的重测信度。因子分析产生5个公共因素,与源量表的5个维度相对应。SRS-22与SF-36在5个维度间的相关性极高,9个维度间的相关性高,有相关的维度有26个。结论:SRS-22简体中文版量表拥有良好的信度及同期效度,可用于青少年特发性脊柱侧凸患者术后疗效随访评价。

OBJECTIVE： To evaluate the validity and reliability of adapted simplified Chinese version of the Scoliosis Research Society-22 （SRS-22） questionnaire. METHODS： The SRS-22, simplified Chinese version, and SF-36 questionnaires were sent to 42 adolescent idiopathic scoliosis patients. Of them, 38 patients （91%）, 7 boys, 31 girls with an average age of （17.8 ± 3.1） years, sent the first questionnaire back. Of the 38 patients, 35 （92%） sent the second questionnaire back. The questionnaire reliability was evaluated by Cronbach＇s a, and test-retest reliability was evaluated by intraclass correlation coefficient （ICC）. The structure validity was evaluated by factor analysis. Concurrent validity of the SRS-22 questionnaire was measured by comparing with domains of the SF-36 questionnaire, which was reflected by Pearson correlation coefficient （r）. RESULTS： The Cronbach＇s e values for 4 domains （function/activity, pain, self-image/appearance, and mental-health） were all 〉 0.70, and the Cronbach＇s a value for satisfaction of management domain was 0.44. The ICC of the SRS-22 questionnaire, 0.94, 0.86, 0.77, 0.74, 0.84, showed a satisfactory reproducibility. Five public factors were obtained by factor analysis compared with the five domains of SRS-22 questionnaire. For the concurrent validity, 5 domains had excellent correlation, 9 had good correlation, and 26 had correlation. CONCLUSION： The adapted simplified Chinese version of the SRS-22 questionnaire has satisfactory reliability and concurrent validity, and might be suitable for post-operative clinical evaluation of Chinese adolescent scoliosis patients.
