The article presents information from two studies of a research program investigating psychosocial antecedents of athletic injury. Study 1 describes the development of the Life Events Survey for Collegiate Athletes (LESCA). The LESCA demonstrated good content validity and provided a stable measure of life stress. The LESCA's validity and the moderating effects of social support were explored in the second study. The LESCA provided a construct-valid measure of life stress and was a better predictor of athletic injury than the Social and Athletic Readjustment Rating Scale. Social support moderated the stress-injury relationship in such a way that LESCA negative life stress accounted for 11% to 22% of injury variances in low-support conditions; LESCA positive life stress accounted for 14% to 20% of injury variances in high-support conditions. Mechanisms underlying the stress-injury relationship and directions for future research are discussed with respect to the model outlined by M. B. Andersen and J. M. Williams in 1988.
本文介绍了一项研究计划中两项研究的信息，该研究计划旨在调查运动损伤的心理社会先兆。研究1描述了大学生运动员生活事件调查（LESCA）的开发过程。LESCA显示出良好的内容效度，并提供了一种稳定的生活压力测量方法。第二项研究探讨了LESCA的效度以及社会支持的调节作用。LESCA提供了一种具有结构效度的生活压力测量方法，并且比社会和运动再适应评定量表更能预测运动损伤。社会支持以这样一种方式调节了压力与损伤之间的关系：在低支持条件下，LESCA负面生活压力占损伤变异的11%至22%；在高支持条件下，LESCA正面生活压力占损伤变异的14%至20%。针对M. B. 安德森和J. M. 威廉姆斯在1988年提出的模型，讨论了压力与损伤关系的潜在机制以及未来研究的方向。
