Reliability and validity of the Turkish version of short form 36 (SF-36) in patients with rheumatoid arthritis

摘要

Ama?: Romatoid artritte Türk?e SF-36’n?n güvenilirlik ve ge?erlili?ini ara?t?rmak. Y?ntemler: ?al??maya al?nan Romatoid artritli hastalar?n demografik ?zellikleri kay?t edildi. Sa?l?k de?erlendirme anketi (HAQ) ve SF-36 formlar? dolduruldu. Hastal?k aktiviteleri DAS-28 kullan?larak hesapland?. Hastalar 3 ay sonra tekrar ?a??r?larak kendilerini ilk geli?lerine g?re nas?l hissettikleri soruldu ve ilk geli?lerinde yap?lan testler tekrarland?. Bulgular: ?al??madaki 141 hastan?n %9,9’u erkek; %90,1’i kad?nd?r. SF-36’n?n güvenilirlik ?al??mas?nda ?l?ek alt boyutlar?n?n Cronbach alfa de?erleri 0,792-0,992 aras?nda de?i?mekte olup, bunun sonucunda SF-36 yüksek düzeyde güvenilir bulunmu?tur. Madde-toplam puan korelasyon katsay?lar? da her bir alt ?l?ek i?in ayr? ayr? hesaplanm??t?r. Fiziksel fonksiyonda 0,436-0,840, fiziksel rol gü?lü?ünde 0,887-0,895; a?r?da 0,861-0,958, sa?l???n genel olarak alg?lanmas?nda 0,564-0,892; vitalite (enerji)’de 0,702-0,841; sosyal fonksiyonda 0,949-0,952; emosyonel rol k?s?tlamas?nda 0,396-0,473 ve mental sa?l?kta 0,456-0,824 aras?nda bulunmu?tur. Daha sonra her iki SF-36 ?l?ümü kar??la?t?r?lm?? ve p0,05 oldu?u i?in ikinci ?l?ümlerde ilk ?l?ümlere g?re bir farkl?l?k saptanmam??t?r. SF 36 ge?erlilik ?al??mas?, beyana dayal? durumlar? ikinci geli?lerinde ilkine g?re de?i?meyen 63 olgu üzerinde yap?lm?? olup; test tekrar test aras?ndaki korelasyon, intra-class korelasyon katsay?lar? ile de?erlendirildi?inde her iki uygulama aras?nda istatistiksel olarak anlaml? ili?ki g?rülmektedir. Bu ?al??mada korelasyon katsay?lar? 0,51 ile 0,78 aras?nda de?i?mektedir. SF-36 puanlar?n?n ilk ve ikinci ?l?ümleri aras?nda istatistiksel olarak anlaml? farkl?l?k g?rülmemektedir (p0,05). Sonu?: Sonu? olarak Türk?e SF-36 Romatoid artritli hastalarda güvenilir ve ge?erli bulunmu?tur. Aim: Investigating reliability and validity of the Turkish version of short form-36 (SF-36) in patients with rheumatoid arthritis Methods: Demographic data of the patients with rheumatoid arthritis were recorded. Health Assessment Questionnaire (HAQ) and Short Form 36 (SF-36) were filled out. Disease activities were computed using Disease Activity Score 28 (DAS-28). Patients were recalled after three months and were asked to state how they felt compared to their first visit, and the same tests were repeated. Results: 141 patients were admitted (9.9% male, 90.1% female). In the reliability study of SF-36, the Cronbach alpha value of the subscales varied in the range 0.792-0.992, hence SF-36 was found to be highly reliable. The item total score correlations were computed for each subscale and were found to be in the ranges: 0.436-0.840 for physical functioning, 0.887-0.895 for role function (physical), 0.861-0.958 for pain, 0.564-0.892 for general health perception, 0.702-0.841 for vitality (energy/fatigue), 0.949-0.952 for social functioning, 0.396-0.473 for role function (emotional) and 0.456-0.824 for mental health. The SF-36 scores from two consecutive visits spaced 3 months apart were compared and the p values were found to be greater than 0.05. The validity study was conducted for the 63 patients whose reported conditions did not change between two visits. The test-retest relation was evaluated using intra-class correlation coefficients, which ranged from 0.51 to 0.78 and the correlations of the two tests were found to be statistically significant. The comparison of SF-36 scores from two consecutive visits, all with p0.05, showed no statistically significant changes. Conclusions: The Turkish version of SF-36 was found to be reliable and valid in patients with rheumatoid arthritis.
