High school athletes are often faced with pressure from all sides such as academics, sports, and social relationship. This study aims to explore what psychological factors enables athletes to better deal with pressure. Purpose: The aim of this study is to examine the prediction of proactive personality and mindfulness on resilience among high school track and field athletes. Methods: A total of 173 high school track and field athletes (110 males and 63 females) were recruited as participants. Their average age was 16.53 years and their average sport participation was 4.97 years. After obtaining informed consent, participants were asked to complete the Proactive Personality Scale, the Mindful Awareness Attention Scale, and the Resilience Scale. Pearson product-moment correlation and simple regression were used to analyze the data. Results: Both proactive personality and mindfulness were significantly positive predictors in predicting high school track and field athletes' resilience. Specifically, the predictive power of proactive personality on resilience (26%) was higher than mindfulness (1%). Conclusion: Proactive personality and mindfulness are both critical variables in predicting the resilience of high school track and field athletes. Hence, an inference may be made that one with high proactive personality demonstrates high resilience. In order to enhance high school track and field athletes' resilience, it is suggested that develop proactive personality through positive behavior and mindfulness training which help improve their abilities of recovering from traumas or setbacks caused by difficulties in life.
