The Role of Mediating Positive and Negative Affect in the Relationship between Mindfulness and Psychological Well-Being of Ilam Students

The present study investigates the mediating role of positive and negative affect in the relationship between mindfulness and psychological well-being of Ilam students. The statistical population of the study included all male and female students of Ilam universities (Azad and State) studying in these universities during the academic year 2019–2020. Therefore, 400 students were selected among these students through multistage cluster sampling method. The study method was descriptive-correlational and purposive. The research data were analyzed by structural equation modeling method using SPSS25 and Amos20 software. The tools used in this study to analyze the variables are: Reef Psychological Well-Being Scale (RSPWB), Five Facet Mindfulness Questionnaire (FFMQ), and Positive and Negative Affect Scale (PANAS). The standard coefficient of the indirect effect of mindfulness on students’ psychological well-being was 0.27 by positive affect and 0.20 by negative affect, which is significant at the P=0.001 level. These results suggest that the variables of positive effect and negative effect mediate the relationship between the variables of mindfulness and psychological well-being. Based on these results, it can be concluded that mindfulness can affect the psychological well-being of individuals by influencing the formation of positive and negative affect.
