The Role of Resilience in Stress Response among Mexican-American and Non-Hispanic White College Students

Previous research has identified that resilience, or the ability to utilize protective factors, effectively buffers the detrimental effects of stress. While the psychological pathways for the protective effect of resilience against the deleterious effects of stress has been well explored and documented, less is known about potential physiological pathways for this relationship. The first goal of this study was to explore the influence resilience has on stress response and positive affect. The second goal was to better understand differences in the relationship between resilience and stress response between Mexican-American and non-Hispanic White individuals, given that Mexican-American individuals encounter additional stress from the process of acculturation. College students (N = 120; 50% Mexican-American, 76.9% Female, mage = 19.6) completed the Trier Social Stress Task (TSST). Measures of resilience, positive affect, and physiological stress response were collected. Examination of stress response utilized measurements of Cortisol, DHEA-S, and heart rate at three time points. Results indicated that while resilience was negatively correlated to stress, depression and anxiety, and positively correlated to positive affect, it was not related concretely to change in physiological variables over the course of the experiment. These findings highlight the importance of considering resilience when examining the psychological impact of stressful experiences, and raise further questions about how physiological response to stress is influenced by the psychological impact of stress and resilience. Further, it was found that amongst Mexican-American students more acculturative stress decreased the protective influence of resilience on positive affect after stress. These results suggest that resilience is an important dynamic to examine with regard to the impact of acculturative stress on minority populations.
