目前的研究调查了团体护理中学龄前儿童的皮质醇产生模式是否受到团体规模、成人与儿童比例、与家人/父母分离等特征的影响；以及托儿服务提供者的关注和刺激的质量。数据来自参加家庭托儿所的学龄前儿童。在家里和托儿所对皮质醇水平进行了采样。家长和老师评估孩子的气质（CBQ、TBQ）。在托儿所，使用看护环境观察评级（ORCE）对孩子们进行观察。儿童保育特征独立于家庭或儿童特征。在家庭托儿所中，儿童一天中的皮质醇模式与托儿所提供的注意力和刺激量显着相关。使用集中注意力/刺激的质量指数测量的中位数分割，高于中位数的环境中的儿童从家庭到托儿所的皮质醇没有变化，而低于中位数的环境中的儿童则表现出从早上到下午皮质醇产生的典型模式的逆转。在家里，这些孩子的皮质醇从早上到下午都出现了预期的下降。托儿所的皮质醇产生模式也与儿童气质相关，情绪消极的儿童和自我控制能力较差的儿童从早上到下午的皮质醇产生量较大。最后，将家庭托儿所的皮质醇产生量与中心托儿所的儿童和未参加全日托儿所的儿童的数据进行了比较。 (C) 2000 Elsevier Science Ltd. 保留所有权利。
The current study investigated whether patterns of cortisol production in preschool-aged children in group care were influenced by characteristics such as group size, adult:child ratio, separation from family/parents; and quality of attention and stimulation from the childcare provider. Data were obtained from preschoolers attending home-based childcare. Cortisol levels were sampled at home and at childcare. Parents and teachers assessed the child's temperament (CBQ, TBQ). At childcare, the children were observed using the Observational Ratings of the Caregiving Environment (ORCE). Childcare characteristics were independent of family or child characteristics. In home-based childcare, children's cortisol patterns over the day correlated significantly with the amount of attention and stimulation provided by the childcare provider. Using a median split on the quality index measure of focused attention/stimulation, children in settings that were above the median exhibited no change in cortisol from home to childcare, while those in settings below the median exhibited a reversal of the typical pattern of cortisol production from morning to afternoon. At home these children exhibited the expected decrease in cortisol from morning to afternoon. Patterns of cortisol production at childcare were also correlated with child temperament with larger increases from morning to afternoon for more emotionally negative children and those with less self-control, Finally, cortisol production in home-based childcare was compared to data from children in center-based childcare and children not enrolled in full-day childcare.
