The purpose of this study was validation of the Persian translation of the Swiss Spinal Stenosis Questionnaire in order to be used by Iranian researchers.
A total of 104 patients with spinal stenosis diagnosis, who were candidates for operative treatment were entered into the study. The patients completed the translated questionnaire in the 1 and the 7 days of admission and 6 months after surgery. Visual analogue scale was used to determine the severity of the pain in the1 day and the 6 month. Discriminant validity, convergent validity, test-retest reliability, internal consistency, ability to detect changes and sensitivity to clinical changes were assessed for the statistical purposes.
Cronbach's α was more than 0.9 for all the items. ICC was about 0.9 for all the items. For symptoms, physical and total items, Cronbach's α was 0.942, 0.957, 0.926 and Intraclass correlation were 0.891, 0.918, 0.862, respectively. Paired t-test was significantly different between the 1 day and the 6 month questionnaire. There was a positive correlation either between the first VAS and the 1 day questionnaire (1 day Q) (r=0.892, ) or between the 6th month VAS and 6 month Q (r=0.940, ). The Pearson's correlation between the difference of the total scores of the 1 day and the 6 month and satisfaction score after surgery showed negative correlation (r= -0.746, ). The effect size was 2.55.
The Iranian version of the Swiss Spinal Stenosis has excellent internal consistency, excellent reliability, good ability to alter with changes, especially parallel with clinical improvement, excellent ability to detect changes, and well either convergent or discriminant validity. II.
本研究旨在验证瑞士脊柱狭窄症问卷的波斯语翻译版本，以便伊朗研究人员使用。
共有104名诊断为脊柱狭窄且适合手术治疗的患者纳入本研究。患者在入院第1天、第7天以及术后6个月完成翻译后的问卷。采用视觉模拟评分法确定术后第1天和6个月时的疼痛严重程度。出于统计目的，评估了判别效度、收敛效度、重测信度、内部一致性、检测变化的能力以及对临床变化的敏感性。
所有项目的Cronbach's α均大于0.9。所有项目的组内相关系数（ICC）约为0.9。对于症状、身体状况和总分项目，Cronbach's α分别为0.942、0.957、0.926，组内相关系数分别为0.891、0.918、0.862。配对t检验显示第1天和6个月问卷之间存在显著差异。术后第1天视觉模拟评分（VAS）与第1天问卷（1天Q）之间（r = 0.892）以及术后6个月VAS与6个月问卷之间（r = 0.940）均呈正相关。术后第1天和6个月总分差值与术后满意度评分之间的Pearson相关性呈负相关（r = -0.746）。效应量为2.55。
瑞士脊柱狭窄症问卷的伊朗版本具有出色的内部一致性、卓越的信度、良好的随变化而改变的能力，尤其是与临床改善平行，出色的检测变化能力，以及良好的收敛效度和判别效度。二、
