This study examined the increase in salivary cortisol from midmorning to midafternoon in 151 children (3.0-4.5 years) in full-time home-based day care. Compared to cortisol levels at home, increases were noted in the majority of children (63%) at day care, with 40% classified as a stress response. Observations at day care revealed that intrusive, overcontrolling care was associated with the cortisol rise. For girls, the cortisol rise was associated with anxious, vigilant behavior, while for boys the rise was associated with angry, aggressive behavior. Child behavior did not mediate or moderate relations between care quality and the cortisol rise, except for evidence that boys scoring low on angry, aggressive behavior were more sensitive to variations in warm, supportive care than boys scoring high on this behavior.
本研究考察了 151 名（3.0-4.5 岁）全日在家托管的儿童从上午到下午唾液皮质醇的增加。与在家时的皮质醇水平相比，在日托中心的大多数儿童（63%）中观察到了增加，其中 40%被归类为应激反应。日托中心的观察结果表明，侵入性、过度控制的护理与皮质醇的上升有关。对于女孩，皮质醇的上升与焦虑、警惕行为有关，而对于男孩，皮质醇的上升与愤怒、攻击行为有关。儿童行为并不能调节或调节护理质量与皮质醇上升之间的关系，除了有证据表明，在愤怒、攻击行为方面得分较低的男孩比在这方面得分较高的男孩对温暖、支持性护理的变化更敏感。
