There is a lack of research regarding the life stressors which male high school and collegiate cross country runners encounter. The Collegiate Student Athlete Life Stress Scale (CSALSS) assess eight life stressor subscales consisting of: performance demands, coach relationships, training adaptations, family relationships, romantic relationships, academic requirements, intrapersonal relationships, and sports injuries. Having an understanding of how these life stressors impact male high school and collegiate cross country runners may provide athletes, parents, and coaches with insight regarding the nature of how these athletes perceive their current life challenges. Purpose: The current study attempted to measure the life stressors which male high school and collegiate cross country runners encounter as assessed by the CSALSS and to determine if differences in the CSALSS subscales exist between the high school and collegiate athletes. It was hypothesized that college cross country runners would have significantly higher scores in the subscales of sports injury, performance demand, coach relationships, and training adaptations. Additionally, it was hypothesized that college student cross country runners' scores on the subscales of academic requirements, intrapersonal relationships, romantic relationships, and family relationships would be similar to high school cross country runners. Methods: Male high school (n=14) and college cross country runners (n=14) completed the CSALSS questionnaire. Independent t-tests were used to compare CSALSS subscales between the high school and collegiate runners (α≤0.05). Results: No differences were found between the high school and collegiate athletes for any of the CSALSS subscales (p< 0.05). The high school and collegiate cross country runners found the subscales concerning sports injuries and academic requirements to be most stressful respectively. Coaching relationships, training adaptations, and interpersonal relationships were the least stressful subscales for these athletes. Conclusion: Within the parameters of this study, male high school and collegiate cross country runners report similar life stressors.
