Salivary biomarker levels and diurnal variation: associations with medications prescribed to control children's problem behavior 总被引：2，自引：1，他引：1
This study examined associations between medications prescribed to control children's problem behaviors and levels of, and diurnal variation in, salivary cortisol (C), testosterone (T), and dehydroepiandrosterone (DHEA). Saliva was collected in the morning, midday, and afternoon from 432 children ages 6-13 years. Relative to a no-medication comparison group, children taking (1) antipsychotics had higher DHEA levels and flat C diurnal rhythms, (2) Ritalin or Adderall had flat T diurnal rhythms, (3) Concerta had higher T and DHEA levels, (4) antidepressants had flat DHEA diurnal rhythms, and (5) hypotensives had flat DHEA diurnal rhythms and higher T levels. Medications prescribed to control children's problem behaviors should be monitored in studies of the endocrine correlates and consequences of developmental psychopathology. 相似文献

Moral development in maltreated and nonmaltreated children was examined by coding child compliance and noncompliance behaviors in a mother-child interaction during a cleanup situation that followed a semistructured free play. Features of child compliance/noncompliance involve a shift from reliance on external controls to internal mechanisms, thereby reflecting child internalization of the maternal agenda. Differences in maltreating versus comparison mothers' use of control strategies (power-assertive and inductive techniques) and their relations to child internalization were examined. Eighty-nine mother-child dyads participated; approximately half of the children (n = 46) had documented histories of maltreatment and the remaining children (n = 43) were nonmaltreated, demographically similar comparison children. Maltreated children were divided into two subgroups: physically abused and neglected. Compared with nonmaltreated children, abused children were found to exhibit less internalization, whereas neglected children displayed significantly more negative affect. No differences were found between groups for the maternal control strategies. However, maltreated and nonmaltreated groups differed in the maternal variables that predicted child internalization. A lower level of maternal negative affect was linked to child internalization in maltreated children, whereas a lower level of maternal joy predicted internalization for the comparison children. The findings suggest that maltreated children exhibit both behavioral and affective differences in their moral development, with differential effects based on the type of maltreatment. The clinical implications for maltreated children's self and moral development are discussed. 相似文献

学校体育是教育系统的重要组成部分,建构理论与实践相结合的学校体育结构,是长期以来学校体育改革面临的严肃、认真的研究问题。学校体育要求教学从竞技化转向素质教育为核心。然而,在实际操作中缺乏理论的指导,教学过程缺失准确的定位。把学校体育标准构建纳入教学之中,确立切实可行的体育标准,实现学校体育真正意义上的“以人为本”。 相似文献
