Abstract

Objective: The aim of this study was designed to investigate the validity, reliability, and cultural adaptation of the Turkish version of the self-reported disability status scale (SRDSS). Materials and Methods: This study was designed as prospective, methodological, and cross-sectional. Turkish translation and cross-cultural adaptation of SRDSS was conducted. SRDSS scores were compared with Expanded Disability Status Scale and Patient Determined Disease Steps to test the concurrent validity. The validity and test-retest reliability of the Turkish SRDSS were investigated in 128 persons with MS. Results: A very strong correlation was found between SRDSS and Expanded Disability Status Scale (r = -0.920, p: 0.000) and Patient Determined Disease Steps (r = 0.857, p = 0.000). The mean of the first test of SRDSS was 1.29 ± 0.59, and the mean of the retest test was 1.30 ± 0.61. A very high correlation was found between test and retest (p < 0.001, r = 0.967). Bland-Altman analysis showed that SRDSS was reproducible with upper and lower limits of agreement of 0.2929 and -0.3089, respectively (bias = -0.008; p = 0.566). Cronbach's alpha coefficient was found to be 0.983 (excellent reliability). For inter-rater agreement, the ICC values in the individual test were 0.967 (954 CI; 0.954–0.977). Conclusion: This study showed that the Turkish version of SDRSS is a valid and reliable measurement tool. In cases where Expanded Disability Status Scale cannot be applied, the Turkish version of SRDSS can be used as an alternative assessment method.

Multipl Sklerozlu Bireylerde Öz Bildirimli Engellilik Durumu Ölçeğinin Türkçe Versiyonunun Geçerliliği ve Güvenilirliği

Abstract

Amaç: Bu çalışmanın amacı, Özbildirimli Engellilik Durumu Ölçeği’nin (SRDSS) Türkçe versiyonunun geçerliliğini, güvenilirliğini ve kültürel uyarlamasını araştırmaktır. Gereç ve Yöntem: Bu çalışma prospektif, metodolojik ve kesitsel olarak tasarlandı. SRDSS'nin Türkçe çevirisi ve kültürler arası uyarlaması yapıldı. Eşzamanlı geçerliliği test etmek için SRDSS puanları Genişletilmiş Engellilik Durum Ölçeği ve Hasta Tarafından Belirlenmiş Hastalık Adımları ile karşılaştırıldı. Türkçe SRDSS'nin geçerlik ve test-tekrar test güvenirliği MS'li 128 kişide incelendi. Bulgular: SRDSS ile Genişletilmiş Engellilik Durum Ölçeği (r = -0.920, p: 0.000) ve Hasta Tarafından Belirlenmiş Hastalık Adımları (r = 0.857, p = 0.000) arasında çok güçlü bir korelasyon bulundu. SRDSS'nin ilk test ortalaması 1.29 ± 0.59, tekrar test ortalaması 1.30 ± 0.61 olarak tespit edildi. Test ile retest arasında çok yüksek bir korelasyon bulundu (p < 0,001, r = 0.967). Bland-Altman analizinde sırasıyla 0.2929 ve -0.3089 üst ve alt uyuşma sınırlarıyla SRDSS'nin tekrarlanabilir olduğunu gösterdi (bias = -0.008; p = 0.566). Cronbach's alpha katsayısı 0,983 (mükemmel güvenirlik) olarak bulundu. Değerlendiriciler arası uyum için, bireysel testteki ICC değerleri 0,967'dir (%95 CI; 0,954–0,977). Sonuç: Bu çalışma, SDRSS'nin Türkçe versiyonunun geçerli ve güvenilir bir ölçme aracı olduğunu göstermiştir. Genişletilmiş Engellilik Durum Ölçeği'nin uygulanamadığı durumlarda, alternatif bir değerlendirme yöntemi olarak SRDSS'nin Türkçe versiyonu kullanılabilir.
