Pearson correlation method and path analysis were used to test the research hypotheses. The results indicated that neuroticism trait (beta = -.10), conscientiousness trait (beta = 0.16) and perfectionism (beta = -0.15) directly predict psychological well-being. Also, the variable of perfectionism mediates the relationship between neuroticism and conscientiousness with psychological well-being.
