Investigation of relationships among anxiety, decision making and intolerance of uncertainty

The aim of this research is to investigate the relationships among trait anxiety, decision-making behavior and intolerance of uncertainty; and also whether these variables differentiate according to gender. The research was conducted with the participation of 105 volunteer university students (female: 62, male: 43) who were studying in various undergraduate programs at Ege University Faculty of Education during the 2018-2019 academic year. Data collection instruments in this study were Information Form, Trait Anxiety Inventory, Iowa Gambling Task (IGT) and Intolerance of Uncertainty Scale (long form). ''Corelational analysis'' and ''independent sample t-test'' were used to analyze the research data. As a result of the analysis; relationships between university students' IGT performance and trait anxiety level was not statistically significant. Also, the relationship between IGT performance and intolerance of uncertainty level was not statistically significant. It was concluded that there were significant positive correlations between trait anxiety level and intolerance of uncertainty level of both female and male students. Besides, the findings revealed that, IGT performance of male students is higher than female students, female students' anxiety level is higher than male students and there was no significant difference between intolerance of uncertainty level of male and female students. The research findings were discussed in the light of the literature and some recommendations were made for future studies.
