Meme Kanseri Sağ Kalım Öz Yeterlik Ölçeği’nin Türkçe Geçerlik ve Güvenirlik Çalışması

Bu araştırmanın amacı Meme Kanseri Sağ Kalım Öz Yeterlik Ölçeği’nin Türkçe geçerlik ve güvenirliğinin yapılmasıdır. Metodolojik tasarımda planlanan araştırma, İstanbul’da bir üniversite hastanesinin meme kliniğinde Ocak-Mayıs 2023 tarihleri arasında gerçekleştirildi. Araştırmaya meme kanseri tedavisi sonrası sağ kalım sürecinde olan 217 kadın dahil edildi. Ölçek 11 madde ve tek boyuttan oluşmakta olup beşli likert şeklinde değerlendirilmektedir. Ölçek dil eşdeğerliği için çeviri geri-çeviri yöntemi uygulandı. Kapsam geçerliği için, uzman görüşü alındı. Yapı geçerliği için Açıklayıcı ve Doğrulayıcı Faktör Analizi kullanıldı. İç tutarlılık için Cronbach’s α ve madde toplam puan korelasyonu için Pearson korelasyon analizi yapıldı. Tekrar test için, ilk veri toplanmasından 3 hafta sonra 55 katılımcıya ölçek tekrar uygulandı. Test-tekrar test güvenilirliği için Sınıf İçi Korelasyon Katsayısı (ICC) hesaplandı. Ölçeğin yakınsama geçerliliği için Genel Öz Yeterlilik Ölçeği kullanıldı. Türkçe’ye uyarlanan ölçeğin uzman görüşleri sonucu Kapsam Geçerlilik İndeksi 0.969, Cronbach’s α güvenirlik katsayısı 0,852 olarak belirlendi. Ölçek maddelerinin korelasyon katsayıları 0.50-0.61 arasında olduğu hesaplandı. Faktör analizinde öz değeri 1’den büyük 11 maddenin 2 faktör altında toplandığı saptandı. Doğrulayıcı faktör analizi ile bu yapı doğrulandı. Araştırma sonucunda meme kanseri sonrası sağ kalım sürecindeki bireylerde Meme Kanseri Sağ Kalım Öz Yeterlik Ölçeği’nin geçerli ve güvenilir bir araç olarak saptandı.

Turkish Validity and Reliability Study of Breast Cancer Self-Efficacy Survivor Scale

The purpose of this research was to define the Turkish validity and reliability of the Breast Cancer Self-Efficacy Survivor Scale. The study was methodological design and was carried out in the breast clinic of a university hospital between January-May 2023 in Istanbul. The study included 217 women who were survivor after breast cancer. The scale contains one dimension, eleven items, and is scored on a five-point Likert scale. Translation-back-translation method was used for language equivalence, expert opinion received, and Exploratory and Confirmatory Factor Analysis were performed for construct validity. Cronbach's α was applied for internal consistency analysis, while Pearson correlation was used for item-total score correlation. The retest was conducted with 55 participants 3 weeks after the initial data collection. Intraclass Correlation Coefficient (ICC) was estimated for test-retest reliability. General Self-Efficacy Scale was used for the convergent validity of the scale. Content Validity Index and Cronbach α reliability coefficient of the scale adapted to Turkish as a result of expert opinions came out to be 0.969, and 0.852 respectively. The correlation coefficients of the scale items were calculated between 0.50 to 0.61. Factor analysis revealed that 11 items with eigenvalues greater than 1 were grouped under 2 factors. Confirmatory factor analysis validated this structure. The study concluded that the Breast Cancer Survivorship Self-Efficacy Scale is a valid and reliable measurement instrument in Turkish society.
