When the studies on the etiology of Orthorexia Nervosa (ON) have been examined in the literature, it is observed that there have been unreconciled results regarding its causality. For this reason, this study aims to examine the predictive effects of eating attitudes, obsessive beliefs, and metacognition variables on the ON tendency in understanding the etiology of ON. Since being a university student is considered a risk factor for developing negative eating behaviors and eating disorders in literature, and university students are also more exposed to popular culture about healthy eating, the sample of the study consisted of 437 university students (Mage = 22.7). In addition to the Demographic Information Form, the Orthorexia Nervosa Scale (ORTO-11), Obsessive Beliefs Questionnaire (OBQ-44), Eating Attitudes Test (EAT-26), and Metacognitions Questionnaire-30 (MCQ-30) were used in the study. Pearson product-moment correlation analysis, ANOVA, t-test, and simple linear regression analyses were applied to test the data. Considering that high scores on the ORTO-11, which measures ON tendency, indicate low ON tendency, the results of the analysis showed that there were significant negative relationships between the independent variables of obsessive beliefs, eating attitudes, and metacognition and ON tendency. Thus, the predictive effects of Obsessive Beliefs Questionnaire total score and its sub-dimensions (responsibility/threat estimation, perfectionism/certainty), Eating Attitudes Test total score and its sub-dimensions (eating preoccupation, restriction), Metacognitions Questionnaire total score and its sub-dimensions (positive beliefs, cognitive self-consciousness, need to control thoughts) on ON tendency were observed. The results obtained from the study were compared and discussed with the findings of similar studies in literature, and it was aimed at shedding light on future research on the etiology of ON tendency.

Alanyazındaki Ortoreksiya Nervoza (ON) etiyolojisi üzerinde yürütülen araştırmalar incelendiğinde nedenselliğine dair uzlaşılamayan sonuçların var olduğu gözlenmektedir. Bu sebeple, bu çalışmada ON etiyolojisinin anlaşılmasına dair yeme tutumları, obsesif inançlar ve üstbiliş değişkenlerinin ON eğilimi üzerindeki yordayıcı etkileri incelenmek istenmektedir. Alanyazında, üniversite öğrencisi olmak olumsuz yeme davranışları ve yeme bozuklukları geliştirmede risk faktörü olarak ele alındığından ve aynı zamanda bu grup sağlıklı yeme ile ilgili popüler kültüre de daha fazla maruz kaldığından araştırmanın örneklemi 437 üniversite öğrencisinden (Ort.yaş = 22.7) oluşmaktadır. Çalışmada Demografik Bilgi Formunun yanında Ortoreksiya Nervoza Ölçeği (ORTO-11), Obsesif İnançlar ölçeği (OİÖ-44), Yeme Tutum Testi (YTT-26) ve Üstbiliş Ölçeği (ÜBÖ-30) kullanılmıştır. Verileri sınamak amacıyla Pearson momentler çarpımı korelasyon analizi, ANOVA, t-test ve basit doğrusal regresyon analizleri uygulanmıştır. ON eğilimini ölçen ORTO-11’den alınan yüksek puanların düşük ON eğilimine işaret ettiğini de göz önünde bulundurarak analiz sonuçlarını ele aldığımızda obsesif inançlar, yeme tutumları ve üstbiliş bağımsız değişkenleri ile ON eğilimi arasında negatif yönde anlamlı ilişkiler olduğu görülmüştür. Böylece, Obsesif İnançlar Ölçeği toplam puanı ve alt boyutları (sorumluluk/tehlike beklentisi, mükemmeliyetçilik/kesinlik), Yeme Tutum Testi toplam puanı ve alt boyutları (yeme meşguliyeti, kısıtlama), üstbiliş toplam puanı ve alt boyutlarının (olumlu inançlar, bilişsel farkındalık, düşünceleri kontrol ihtiyacı) ON eğilimi üzerindeki yordayıcı etkileri gözlenmiştir. Araştırmadan elde edilen sonuçlar alanyazındaki benzer çalışmaların bulguları ile karşılaştırılarak tartışılmış ve bu çalışmanın, ileride ON eğiliminin etiyolojisi üzerine yapılacak araştırmalara ışık tutması amaçlanmıştır.
