Tested male Ss (N = 34) to determine how changes in the urinary excretion patterns of selected catecholamines and their metabolites affect the multivariate relationships involving variables that measure physical fitness condition and selected personality characteristics. Urine specimens were collected from each S after sleep and during occupational activities and analyzed for six catecholamine-related variables. Those measures were combined with six personality variables (MMPI) and a physical fitness score (Ismail Criterion), and subjected to first- and second-order factor analyses. The findings indicated an association between low physical fitness and high self-reported anxious depression during the occupational period, but not at rest. The changes in the factor structures were statistically mediated by changes in the concentrations of the biochemical variables across the collection periods. This suggests that the relationships between physical fitness and personality are augmented during catecholamine reactivity to occupational stress.
对34名男性受试者进行测试，以确定所选儿茶酚胺及其代谢物的尿排泄模式变化如何影响涉及测量身体健康状况和所选人格特征的变量的多变量关系。在睡眠后和职业活动期间从每个受试者收集尿液样本，并分析六个与儿茶酚胺相关的变量。这些测量值与六个个性变量（明尼苏达多项人格调查表）和一个身体健康评分（伊斯梅尔标准）相结合，并进行一阶和二阶因子分析。研究结果表明，在职业活动期间，身体健康状况不佳与自我报告的高度焦虑抑郁之间存在关联，但在休息时不存在这种关联。跨收集期生化变量浓度的变化在统计学上介导了因子结构的变化。这表明在儿茶酚胺对职业压力的反应过程中，身体健康与人格之间的关系得到了增强。
