The Impact of Cognitive Flexibility and Optimism on Burnout and Stress Levels in Medical Students: A Psychological Perspective

Abstract: This study explored the predictive role of cognitive flexibility and optimism on academic burnout and perceived stress among Bangladeshi medical students. A total of 250 participants (49.6% female, 50.4% male; M_age = 22.55, SD = 1.63) were recruited from various medical institutions using a purposive-incidental sampling method. Participants completed five standardized self-report instruments translated into Bangla: the Cognitive Flexibility Inventory (CFI), Maslach Burnout Inventory-Student Survey (MBI-SS), Life Orientation Test-Revised (LOT-R), Perceived Stress Scale-10 (PSS-10), and a demographic questionnaire. Data were analyzed using SPSS (v27). Pearson’s correlation showed that cognitive flexibility and optimism were significantly positively correlated (r = .294, p < .01), and both were significantly negatively correlated with burnout (r = –.442, r = –.369, respectively) and perceived stress (r = –.465, r = –.280, respectively). Hierarchical regression analysis revealed that cognitive flexibility and optimism significantly predicted both burnout (R² = .258) and perceived stress (R² = .239), with cognitive flexibility emerging as the stronger predictor in both models. Independent samples t-tests showed significant gender differences in cognitive flexibility and perceived stress, with males scoring higher in flexibility and females reporting more stress. No significant gender differences were found in optimism or burnout. These findings suggest that cognitive flexibility and optimism may act as protective psychological resources, buffering against stress and burnout among medical students. Interventions aimed at enhancing these traits could promote mental well-being and resilience in high-pressure academic environments. The study adds culturally relevant insights into the psychological mechanisms underlying student well-being in a South Asian medical education context.
