The novel Coronavirus-2019 (COVID-19) pandemic, as in many areas of life, has also created many uncertainties related to education. One of the student group affected by this uncertainty is the senior students studying at the Faculty of Sport Sciences. The aim of this research is to examined the mediating role of coping styles with stress (CSS) between intolerance of uncertainty (IU), and positive expectations (PFE) towards future in a sample of senior students of the faculty of sport sciences. The participant group of the research consists of 423 senior students, 170 female and 253 male, studying at sports science faculties of 8 different universities and participating voluntarily in the research. Research data were collected during the first wave of the COVID 19 pandemic through the Intolerance of Uncertainty Scale, the Coping Styles Inventory, and the Positive Future Expectations Scale. Mediation analysis and Bootstrapping test results confirm the mediating effect of CSS-effective and ineffective orientation in the relationship between students’ IU and PFE. According to the findings of this research; As the level of IU decreases, CSS-effective orientation increases and PFE increases through effective orientation. On the other hand, as the IU level increases, CSS-ineffective orientation scores increase and PFE decreases through ineffective orientation. The findings are discussed within the framework of the Intolerance of Uncertainty, positive expectations towards future and stress and coping related literature.

COVID-19 pandemisi, çoğu yaşam alanında olduğu gibi eğitim ile ilgili birçok belirsizliği de doğurmuştur. Bu belirsizlikten en yoğun etkilenen öğrenci gruplarından biri de Spor Bilimleri Fakültelerinde öğrenim gören son sınıf öğrencileridir. Bu araştırmanın amacı, Spor Bilimleri Fakültesi son sınıf öğrencilerinin belirsizliğe tahammülsüzlük (BT) düzeyi ve olumlu gelecek beklentileri (OGB) arasında stresle başa çıkma (SB) tarzlarının rolünü ortaya koymaktır. Araştırmanın katılımcı grubunu 8 farklı üniversitenin spor bilimleri fakültelerinde öğrenim gören ve araştırmaya gönüllü katılan 170 kadın, 253 erkek toplam 423 son sınıf öğrencisi oluşturmaktadır. Araştırma verileri COVID-19 pandemisi I. dalgası esnasında Belirsizliğe Tahammülsüzlük Ölçeği, Stresle Başa Çıkma Tarzları Ölçeği, Olumlu Gelecek Beklentisi Ölçeği aracılığıyla toplanmıştır. Aracılık analizi ve Bootstrap testi sonuçları, öğrencilerin BT düzeyleri ve OGB arasındaki ilişkide stresle başa çıkmada etkili ve etkisiz yönelimin aracılık etkisini doğrulamaktadır. Bu araştırmanın bulgularına göre; BT düzeyi düştükçe SBT-Etkili yönelim artmakta ve etkili yönelimin aracılığı ile OGB artmaktadır. Öte yandan BT düzeyi arttıkça SBT- etkisiz yönelim puanları artmakta ve etkisiz yönelimin aracılığı ile OGB azalmaktadır. Bulgular belirsizliğe tahammülsüzlük, geleceğe yönelik olumlu beklentiler ve stresle başa çıkma ile ilgili literatür çerçevesinde tartışılmıştır.
