The present study examined the response of children to a stressor condition. Urine samples were collected from 38 children between ages 10 and 12 preceding a class presentation and again one week later, when no unusual event was occurring. Cognitive tasks and a state anxiety inventory were administered on both occasions. Personality and stressor situation inventories (hypothesized antecedent factors) were completed. Bidirectional changes in catecholamine levels were demonstrated (adrenalin: 55% of the children showed an increase, 29% a decrease; noradrenalin: 47% increase, 40% decrease; 3-methoxy-4-hydroxyphenethylene glycol: 40% increase, 42% decrease). Distinct differences in gender distribution and cognitive performance were demonstrated for the increase and decrease subgroups. It was suggested that both increases and decreases in catecholamine levels represent responses to the stressor situation, with an increase representing an adaptive response and a decrease representing a less adaptive response.
本研究考察了儿童对应激源状况的反应。在38名10至12岁儿童进行课堂展示之前采集尿液样本，一周后当没有异常事件发生时再次采集。两次采集时均进行了认知任务和状态焦虑量表测试。完成了人格和应激源状况量表（假设的先行因素）。结果显示儿茶酚胺水平存在双向变化（肾上腺素：55%的儿童水平升高，29%降低；去甲肾上腺素：47%升高，40%降低；3-甲氧基-4-羟基苯乙二醇：40%升高，42%降低）。升高和降低亚组在性别分布和认知表现上存在明显差异。研究表明，儿茶酚胺水平的升高和降低均代表对应激源状况的反应，升高代表适应性反应，降低代表适应性较差的反应。
