عنوان انگلیسی Reliability and validity of the Swiss Spinal Stenosis Questionnaire for Iranian patients with Lumbar Spinal Stenosis
چکیده انگلیسی مقاله Background: the purpose of this study is validation of the Persian translation of the Swiss spinal stenosis questionnaire in order to use by Iranian researchers. Methods: A total of 104 patients with diagnosis of the spinal stenosis whom were candidates for operative treatment were entered to the study. Translated questionnaire was completed by the patients in the 1st and the 7th days of admission and 6th month after surgery. Visual analogue scale was used to determine severity of the pain in the1st day and the 6th month. Discriminant validity, convergent validity, test-retest reliability, internal consistency, ability to detect changes and sensitivity to clinical changes was assessed for the statistical purpose. Results: Cronbach's α was more than 0.9 for all items. ICC was about 0.9 for all 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 1st day and 6th month questionnaire. There was positive correlation either between the first VAS and the 1st day Q (r=0.892, P=0.000) or between the 6th month VAS and the 6th month Q (r=0.940, P=0.000). The Pearson's correlation between difference of total scores of the 1st day and the 6th month and satisfaction score after surgery showed negative correlation (r= -0.746, P=0.000). The effect size was 2.55. Conclusion: 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.
