Davranışsal finans, piyasa anomalilerinin yanı sıra bu anımalilere neden olan önyargıların incelenmesini de konu almaktadır. Literatüre bakıldığında kişilerin karar süreçleri üzerinde etkisi olduğu belirtilen çok sayıda önyargıdan bahsedildiği görülmektedir. Bunlar arasında üzerinde ayrıca durulan önyargıların ise kendine aşırı güven, kontrol yanılsaması ve aşırı iyimserlik olduğu dikkati çekmektedir. Bu çalışmada bu üç önyargının ölçülmesini hedefleyen ifadelerden oluşan ölçeklerin Türkiye’de üniversite öğrencileri üzerindeki güvenilirliği ve geçerliliği test edilmiştir. Önyargıları ölçülmesini hedefleyen ve bu çalışmada kullanılan ölçeğin ilk halinde 19 madde yer almaktadır. Öğrencilerin demografik bilgilerini de içeren anket formu farklı üniversitelerde öğrenim gören toplam 522 öğrenciye uygulanmıştır. Yapılan analizler sonucunda ölçeğin son halinin Cronbach Alfa değerinin 0,825 olduğu ve ölçekte yer alan ifadelerin 4 faktör altında toplandığı tespit edilmiştir.
