Psychological well-being is a new concept derived from positive psychology and is one of the important indicators in personal and social growth and development as well as in the evaluation of educational systems. This variable is influenced by various factors such as personality traits and perfectionism. The aim of this study was to predict psychological well-being based on personality traits with respect to the mediating role of perfectionism in students. The research method was descriptive-correlational. The statistical population was all undergraduate students of Shiraz University in 2021. The research sample was 372 people who were selected by accessible sampling method. Reef Psychological Well-being Questionnaire (1989), NEO Personality Questionnaire (1985) and Frost Multidimensional Perfectionism Scale (FMPS) (1990) were used to collect data. 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. In general, the research findings support the role of personality traits in psychological well-being directly and through perfectionism.
