本研究前瞻性地探讨了性格乐观和情境乐观对法律系学生第一学期情绪(N=90)和免疫功能变化(N=50)的影响。乐观与更好的情绪、更多的辅助性T细胞和更高的自然杀伤细胞杀伤活性有关。回避应对部分解释了乐观情绪与情绪之间的关系。在免疫参数中，情绪部分解释了乐观-辅助T细胞关系，感知压力部分解释了乐观-细胞毒性关系。个体在期望、评估和情绪上的差异可能对理解心理和免疫压力反应很重要。
This study explored prospectively the effects of dispositional and situational optimism on mood (N = 90) and immune changes (N = 50) among law students in their first semester of study. Optimism was associated with better mood, higher numbers of helper T cells, and higher natural killer cell cytotoxicity. Avoidance coping partially accounted for the relationship between optimism and mood. Among the immune parameters, mood partially accounted for the optimism-helper T cell relationship, and perceived stress partially accounted for the optimism-cytotoxicity relationship. Individual differences in expectancies, appraisals, and mood may be important in understanding psychological and immune responses to stress.
