Validity and Reliability Study of the Food Insecurity Experience Scale (Fies) in Turkish Adults

Öz

Objective: This study aimed to validate the “Food Insecurity Experience Scale(FIES)” and address the lack of a reliable and valid tool for assessing food insecurity in the Turkish population. Materials and Methods: The study was conducted between July and August 2025 with 469 participants aged 18 years. Content validity of the scale was evaluated using the Davis method by 10 nutrition and dietetics experts. The Content Validity Index was calculated, with values ranging from 0.80-1.00. To assess construct validity, exploratory factor analysis(EFA) and confirmatory factor analysis were performed. Results: The Kaiser-Meyer-Olkin(KMO) value was 0.858, Bartlett’s test yielded χ²=1369.604 (p<0.001). EFA confirmed a unidimensional structure, with factor loadings ranging from 0.557-0.727. Cronbach’s alpha was 0.850, all item-total correlations were positive. Removing any item did not significantly increase the Cronbach’s alpha value. Conclusion: The Turkish version of FIES is valid and reliable, providing a suitable instrument for assessing food insecurity among Turkish adults.

Gıda Güvensizliği Deneyim Ölçeği (Fies)’nin Türk Yetişkinlerinde Geçerlik ve Güvenirlik Çalışması

Öz

Amaç: Bu çalışmanın amacı, “Food Insecurity Experience Scale (FIES)” ölçeğini doğrulamak ve Türk toplumu için geçerli ve güvenilir bir besin güvencesizliği değerlendirme aracı eksikliğini gidermektir. Yöntem: Araştırma Temmuz–Ağustos 2025 tarihleri arasında 18 yaş ve üzerindeki 469 birey ile yürütülmüştür. Ölçeğin içerik geçerliliği, beslenme ve diyetetik alanında uzman 10 akademisyen tarafından Davis yöntemi ile değerlendirilmiştir. İçerik geçerlilik indeksi (CVI) hesaplanmış ve değerlerin 0,80–1,00 aralığında olduğu belirlenmiştir. Ölçeğin yapı geçerliliğini incelemek amacıyla açıklayıcı faktör analizi (AFA) ve doğrulayıcı faktör analizi (DFA) uygulanmıştır. Bulgular: KMO değeri 0,858, Bartlett testi χ²=1369,604 (p<0,001) olarak bulunmuştur. AFA, ölçeğin tek faktörlü yapısını doğrulamış, faktör yüklerinin 0,557–0,727 arasında değiştiği görülmüştür. Cronbach α katsayısı 0,850 olarak saptanmıştır. Madde-toplam korelasyonlarının tamamı pozitif bulunmuş, herhangi bir maddenin çıkarılması Cronbach alfa değerinde anlamlı bir artışa yol açmamıştır. Sonuç: FIES’in Türkçe versiyonu geçerli ve güvenilir bulunmuş, Türkiye’de yetişkinlerde besin güvencesizliğini değerlendirmek için kullanılabilecek uygun bir ölçektir.
