Abstract

Bu çalışma, 855 Çukurova Üniversitesi öğrenci anketine dayanarak pozitif ve negatif etkilerin, eğilimsel iyimserlikile yaşam memnuniyeti arasındaki ilişkiye aracılık edip etmediğini ve moderatör olup olmadıklarını araştırmaktadır. Bu amaçla, pozitif ve negatif etkilerin dolaylı ve etkileşim etkilerinin anlamlılığı hesaplanmıştır. Parametrik olmayan Spearman korelasyon analizi, eğilimsel iyimserliğin ve duygulanımların yaşam memnuniyeti ile anlamlı bir ilişkiye sahip olduğunu ortaya koymuştur. Pozitif ve negatif etkilerin potansiyel aracı ve moderatör olup olmadığını belirlemek için hiyerarşik regresyon analizi kullanılmıştır. Eğilimsel iyimserlik ile yaşam memnuniyeti ilişkisini pozitif ve negatif etki bileşenleri üzerinden gösteren yapısal bir model tahmin edilmiştir. Etkilerin aracılık rolünü incelemek için eğilimsel iyimserliğin dolaylı etkilerinin anlamlılığı test edilmiştir. Hiyerarşik regresyon analizi sonuçları, pozitif ve negatif etkilerin iyimserliğin üstünde ve ötesinde yaşam memnuniyetini anlamlı bir şekilde yordadığını göstermiştir (F(2,851)=76.21, ∆R2=.120, p<.001). Maksimum olabilirlik tahmin sonuçları, iyimserliğin dolaylı etkisinin pozitif ve negatif etkiler yoluyla anlamlı olduğunu göstermiştir. Yani, pozitif ve negatif etkilerin iyimserlik ve yaşam memnuniyeti arasında anlamlı (z=11.12, p<.001) bir aracı rolü olduğunu göstermektedir. Hiyerarşik regresyon analizi, bu arabuluculuğun kısmi olduğunu ve ayrıca PA'nın moderatör olduğunu ortaya koymuştur. Marginal analiz, özellikle orta derecede alert ve hevesli olmanın moderatör olduklarını göstermiştir.

The effects of affectivites over the relationship of dispositional optimism with life satisfaction of university students

Abstract

This study investigates whether positive and negative affects (affectivities) mediate and moderate the relationship between dispositional optimism and life satisfaction based on a survey of 855 Çukurova University students. For this purpose, the significance of indirect and interaction effects of positive and negative affects are estimated. Nonparametric Spearman correlation analysis showed significant correlations between optimism,affects and life satisfaction. Hierarchical regression analysis is performed to determine whether the affect is potential mediator and moderator variable. A structural model which shows the life satisfaction relationship with optimism through components of positive and negative affects estimated. The significance of the indirect effects of optimismistested to examine the mediating role of the affects. Hierarchical regression analysis results showed that the affects significantly predicted life satisfaction above and beyond optimism(F(2,851)=76.21, ∆R2=.120, p<.001). The maximum likelihood estimation results indicated significance of indirect effect of optimismvia affects. That is, the affects significantly mediated optimism(z=11.12, p<.001) over life satisfaction. Hierarchical regression analysis revealed that the mediation was partial and that PA was a moderator. Marginal analysis further showed that particularly being moderately alert and being moderately enthusiastic were moderators.
