Abstract
Amaç: Stigma, diğer kronik hastalıklarda olduğu gibi multipl skleroz hastalarının da biyopsikososyal yaşamlarını ve tedavi süreçlerini etkileyen bir davranıştır. Bu çalışmanın amacı, kısa ve güvenilir bir ölçek olan Reece Stigma Ölçeği-Multiple Sclerosis'i (RSS-MS) Multipile Skleroz-Reece Stigma Sakala (MS-RSS) adıyla Türkçeye uyarlamak ve geçerlik ve güvenilirlik çalışmasını yapmaktır.
Gereç ve Yöntem: Çalışmanın örneklemini Multipl Skleroz tanısı almış ve çalışmaya gönüllü olarak katılmayı kabul eden 416 birey oluşturdu. Çalışmaya katılmayı kabul eden bireylere "Kişisel Bilgi Formu" ve Türkçe'ye çevrilmiş "MS-RSS" uygulandı. Ölçeğin yapı geçerliliğini incelemek için Doğrulayıcı Faktör Analizi (DFA) yapıldı. Ölçeğin güvenilirliğini hesaplamak için iç tutarlılık katsayısı (Cronbach's Alpha) ve madde-toplam korelasyonları analiz edildi.
Bulgular: Minimum Ki-kare değerinin istatistiksel olarak anlamlı olduğu ve diğer uyum indeksi değerlerinin istenen aralıkta olduğu bulundu. CFA'da Standardize Regresyon Katsayıları (std. β) 0,30'un üzerinde, pozitif ve anlamlıydı. Cronbach'ın Alfa katsayısı 0,844 ve madde-toplam korelasyonları 0,334 ile 0,742 arasında değişiyordu.
Sonuç: Sonuç olarak MS-RSS, MS hastalarında damgalanma algısının değerlendirilmesinde etkili bir araç olarak kullanılabilir.

Abstract
Objective: Stigma is a behavior that affects the bio-psycho-social lives of patients with multiple sclerosis, as it does in other chronic diseases, as well as their treatment processes. The aim of this study is to adapt the short and reliable Reece Stigma Scale-Multiple Sclerosis (RSS-MS) into Turkish under the name of Multipile Skleroz-Reece Stigma Sakala (MS-RSS) and to conduct its validity and reliability study.
Materials and Methods: The study sample consisted of 416 individuals diagnosed with Multiple Sclerosis who voluntarily agreed to participate in the study. The "Personal Information Form" and the "MS-RSS" translated into Turkish were applied to individuals who agreed to participate in the study. Confirmatory Factor Analysis (CFA) was conducted to examine the construct validity of the scale. To calculate the reliability of the scale, internal consistency coefficient (Cronbach's Alpha) and item-total correlations were analyzed.
Results: It was found that the minimum Chi-square value was statistically significant and the other fit index values were within the desired range. In CFA, the Standardized Regression Coefficients (std. β) were above 0.30, positive and significant. Cronbach's Alpha coefficient was 0.844 and item-total correlations ranged between 0.334 and 0.742.
Conclusion: In conclusion, the MS-RSS can be used as an effective tool in assessing the perception of stigma among MS patients.
