ÖZET
 Amaç: Bu araştırma, hemşirelerin enteral beslenme uygulamalarına yönelik öz yeterliklerini ölçebilecek bir ölçme aracının geliştirilmesi ve psikometrik özelliklerinin incelenmesi amacıyla uygulandı. Gereç ve Yöntemler: Bu araştırma metodolojik tasarımda uygulandı. Ekim-Kasım 2022 tarihleri arasında İstanbul'da bir hastanede yürütülen çalışmanın örneklemini, en az 6 ay mesleki tecrübesi olan 18 yaş ve üstü gönüllü 302 hemşire oluşturdu. Ölçek için 98 maddelik soru havuzu oluşturuldu ve uzman görüşüne sunuldu. Uzman görüşleri LAWSHE analizi ile değerlendirildi. Altmış maddelik taslak form hazırlandı. Ölçeğin geçerliği, kapsam ve yapı geçerliği ile test edildi. Ayrıca güvenirlik katsayıları ve madde toplam korelasyonları incelendi, alt üst %27'lik dilim karşılaştırması ve test-tekrar test uygulandı. Bulgular: Açımlayıcı faktör analizi sonucunda, 37 maddelik ölçeğin 2 faktörlü yapının toplam varyansın %44,74'ünü açıkladığı belirlendi. Maddelerin faktör yüklerinin 0,37-0,75 arasında olduğu belirlendi. Doğrulayıcı faktör analizi sonucu model uyumuna ilişkin x2/df değeri 2,10 ve uyum indeksleri yaklaşım hatasının kareli ortalamasının karekökü=0,056; Uyum İyiliği İndeksi=0,80; Marjinal Artış Uyum İndeksi=0,89; Karşılaştırmalı Uyum İndeksi=0,88; Normlaştırılmış Uyum İndeksi=0,80 olarak bulundu. Madde toplam korelasyonlarının 0,35- 0,77 arasında olduğu saptandığı. Ölçeğin tamamı için Cronbach alfa değeri 0,94 olarak belirlendi. Sonuç: Yapılan tüm analizlere göre Enteral Beslenme Uygulamaları Öz Yeterlik Ölçeği, hemşirelerin enteral beslenme konusundaki öz yeterliklerini ölçebilecek geçerli ve güvenilir bir ölçme aracıdır.

ABSTRACT
 Objective: This research was carried out to develop a measurement tool that can measure nurses' self-efficacy for enteral nutrition practices and to examine their psychometric properties. Material and Methods: This research was applied in methodological design. The study sample, which was carried out in a hospital in İstanbul between October-November 2022, consisted of 302 volunteer nurses aged 18 and over with at least 6 months of professional experience. A 98- item question pool was created for the scale and presented to expert opinion. Expert opinions were evaluated by LAWSHE analysis. A 60- item draft form was prepared. The validity of the scale was tested with content and construct validity. In addition, reliability coefficients and item-total correlations were examined, a top-down 27% slice comparison and test-retest were applied. Results: As a result of the exploratory factor analysis, it was determined that the 2-factor structure of the 37- item scale explained 44.74% of the total variance. It was determined that the factor loads of the items were between 0.37-0.75. As a result of confirmatory factor analysis, x2/df value for model fit was 2.10 and fit indexes were Root Mean Square Error of Approximation=0.056; Goodness-of-fit Index=0.80; Incremental Fıt Index=0.89; Comparative Fit Index=0.88; Normed Fit Index was found to be 0.80. Item-total correlations were found to be between 0.35-0.77. The Cronbach's alpha value for the entire scale was determined as 0.94. Conclusion: According to all analyzes, the Enteral Nutrition Practices Self-Efficacy Scale is a valid and reliable measurement tool that can measure the enteral nutrition self-efficacy of nurses.
