The mediating role of emotion regulation in the relationship between personality traits and perfectionism with sleep quality in students

The present study was conducted with the aim of determining the mediating role of emotion regulation in the relationship between personality traits and perfectionism with sleep quality in college students. The descriptive-correlational research method used structural equation modeling. The statistical population of the research consisted of all students of Tabriz University in ۲۰۲۲, from which ۲۴۰ students were selected by cluster random sampling. Data were collected using the Pittsburgh Sleep Quality Index (PSQI; Buysse et al., ۱۹۸۹), the Five-Factor Personality Inventory (NEO-FFI; Costa & McCrae, ۱۹۸۹), Tehran’s Multidimensional Perfectionism Scale (Besharat, ۲۰۱۶), and the Emotion Regulation Questionnaire (ERQ; Gross, ۲۰۰۳). The results of structural equation modeling showed that the proposed model had a favorable fit. The results indicated a significant and direct positive relationship between perfectionism, extraversion, openness to experience, agreeableness, and conscientiousness with emotion regulation and sleep quality, while there was a significant negative and direct relationship between neuroticism and emotion regulation and sleep quality (P < ۰.۰۱). The results of the bootstrap test revealed that emotion regulation plays a mediating role between personality traits and sleep quality, as well as between perfectionism and sleep quality (P < ۰.۰۱). The findings of this study suggest that emotion regulation mediates the relationship between personality traits and sleep quality, as well as between perfectionism and sleep quality.The present study was conducted with the aim of determining the mediating role of emotion regulation in the relationship between personality traits and perfectionism with sleep quality in college students.
