This study examines the relationships between resilience level and perceived parental relationship, cognitive emotion regulation, and personality traits in emerging adulthood. The sample of the research consists of undergraduate students whose age range is 18-25. The study was conducted with 609 people, 317 (52%) female and 292 (48%) male students. Resilience Scale (RS), The Barrett-Lennard Relationship Inventory (BLRI), Cognitive Emotion Regulation Questionnaire (CERQ), Big Five Inventory (BFI) and Demographic Information Form were applied to the participants. One-way ANOVA analysis, Pearson's Correlation Coefficient Analysis and Hierarchical Linear Regression analysis were used to analyse the data. In the study, resilience mean scores of female students were found to be higher than male students. A positive relationship was found between the resilience scores of university students and their perceived parental relationship scores. A significant negative relationship was found with self-blame, which is the sub-dimension of cognitive emotion regulation. A positive and significant relationship was found with the other sub-dimensions of cognitive emotion regulation, respectively; acceptance, rumination, positive refocusing, re-focus on the plan, positive reappraisal, putting into perspective, other-blame and catastrophising. At the same time, a significant positive correlation was found between resilience scores and personality traits dimensions. According to the hierarchical regression analysis findings, it was concluded that perceived parental relationship, especially perceived father relationship, the catastrophising sub-dimension of cognitive emotion regulation, and personality traits predicted resilience. The study findings were discussed according to the relevant field, and recommendations were presented.
