Abstract enAlthough the importance of investigating positive concepts is huge for a healthier life, in our country there are few studies investigating psychological well-being, happiness and life satisfaction. Optimism, happiness and life satisfaction are considered as important concepts of positive psychology. This study aims to investigate the effect of optimism on happiness and life satisfaction. The sample of the study constitutes 394 (225 female/169 male) young adults who study in university. In order to obtain data,"The Satisfaction with Life Scale" (SWLS), "The Life Orientation Test" (LOT), and "Oxford Happiness Questionnaire Short Form" (OHQ-SF) were used. To evaluate the data descriptive statistical methods (Number, Percentage, Average, Standard deviation) were used. T-test was used for comparison of quantitative data. The correlation between dependent and independent variables of the study is tested with Pearson correlation analysis, and the effect was tested with regression analysis. Findings are calculated in 95% confidence interval, and 5%significance level. The findings of the study indicate that optimism is positively correlated with happiness and life satisfaction. In accordance with these findings, we can say that in our country insufficient studies were conducted to investigate psychological wellbeing, happiness and life-satisfaction while investigating positive concepts is important for a healthier life. There must be more studies in this area
