改良版脊柱侧凸研究学会问卷表在中国青少年脊柱侧凸患者中的应用

The Modified Scoliosis Research Society Questionnaire is More Suitable for Chinese Adolescent Patients with Scoliosis

目的:评价改良版脊柱侧凸研究学会(SRS)问卷表的信度和效度,使之更准确为中国青少年脊柱患者服务。方法:组成专项组对简体中文版脊柱侧凸研究会22项患者量表(SRS-22)进行调适和修改,形成改良版SRS量表,将改良版SRS量表及相对公认的简体中文版SRS-22量表寄给84例青少年特发性脊柱侧凸患者,对寄回的63例(75%)患者再寄第二份调查表,54例(86%)患者寄回第二份调查表。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SRS-22各维度比较获得,评价指标为pearson’s相关系数(r)。结果:改良版在5个维度(功能活动度、疼痛、自我形象、精神健康、治疗满意度)的Cronbach’sα系数都大于或等于0.8,5个维度的组内相关系数分别为0.95、0.90、0.85、0.75、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,改良版与SRS-22在5个维度间相关性极高。结论:改良版SRS患者量表拥有同英语国家一样好的信度和效度,对简体中文版SRS-22量表作必要的符合国情调适和修改,更符合Asher等最初编制英文版SRS-22量表的设计意图。

Objective：To evaluate the validity and reliability of the modified Scoliosis Research Society questionnaire and to make it serve Chinese Adolescent Patients with Scoliosis better. Methods：The simplified Chinese version of the Scoliosis Research Society-22（SRS-22） questionnaire was adapted to form the modified SRS questionnaire. The two questionnaires were mailed to 84 patients with adolescent idiopathic scoliosis. 63 patients （75%） responded to the first set of question- naire, among them 54 patients（86%） meanwhile returned their second survey as well. The reliability of the modified SRS questionnaire was determined by Cronbach＇s a value and the reproducibility was determined by intraelass correlation coeffi- cient. The construct validity of the questionnaire was measured by factor analysis . Concurrent validity was measured by comparing with the SRS-22 ,and the measurement was made using the Pearson correlation coefficient（r）. Results： As for the modified SRS questionnaire, the Cronbach＇s α values of five dimensions（functional activity, pain, self image, mental health, satisfaction degree） were greater than or equal to 0.8,and intraclass correlation coefficient of five dimensions were 0.95,0. 90,0.85,0.75 and 0.84 respectively which showed better reproducibility. Factor analysis produced five common factors that were corresponding to five dimensions of source questionnaire. The five dimensions in the two questionnaires were rel- atively similar. Conclusion： The modified SRS questionnaire has the same validity and reliability as the SRS-22 question- naire. Modification of the simplified Chinese version of the SRS-22 questionnaire according to Chinese national condition is more suitable to Asher＇s intention in constructing English version of the SRS-22 questionnaire.
