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

Seventy-eight postinstitutionalized (PI) children adopted at ages 17–36 months were assessed 2, 8, 16, and 24 months postadoption on measures of cortisol and parenting quality, and compared to same-aged children adopted from foster care (FC, n = 45) and nonadopted children (NA, n = 45). In kindergarten (Mage = 6.0 years), teachers, parents, and trained observers completed measures of peer relationships and attention deficit hyperactivity disorder (ADHD) symptoms. PI children had more peer problems and ADHD symptoms according to teachers and observers than NA children with FC children in between, whereas both PI and FC children were at significantly greater risk of hypocortisolism (i.e., blunted cortisol diurnal rhythm and reactivity). Hypocortisolism and ADHD symptoms mediated the association between preadoption adversity and peer difficulties. Higher postadoption parenting quality was protective.  相似文献

The transition to out‐of‐home child care brings a number of challenges for children, including complex peer interactions and extended separations from parents. Children often show a midmorning to afternoon rise in cortisol on child‐care days, compared to the typical diurnal decline seen at home. Changes in cortisol were examined in a wide age range of children (N = 168; 1.2 months to 8 years, M = 3.27 years) during the 10‐week transition to a new child‐care setting. Structural equation modeling using latent change scores showed that children experienced an increase in the cortisol rise at child care across the 10‐week transition. Furthermore, child age moderated the difference between home‐ and child‐care cortisol patterns. Findings are placed in a developmental context, and potential implications and future directions are discussed.  相似文献

The purpose of the study was to measure the impact of resource interventions upon the level of peer acceptance and self-concept. Subjects were 82 children from 5 elementary schools in central Pennsylvania. The Experimental group (N = 41) consisted of learning disabled children in regular classes with resource room interventions. The Control group (N = 41) consisted of nonlearning disabled children stratified by sex and classrooms. All subjects were group administered a self-concept measure and a peer acceptance measure early in the school year and again at the end of the school year. Separate 3-way analysis of variances with repeated measures revealed that the LD children were significantly lower in self-concept scores and peer acceptance ratings at both testing occasions than were the nonLD children. The resource based program did not result in significant changes in either self-concept or peer acceptance after one year for the LD group.  相似文献

The present study examined the interactive effects of school norms, peer norms, and accountability on children's intergroup attitudes. Participants (n = 229) aged 5–11 years, in a between‐subjects design, were randomly assigned to a peer group with an inclusion or exclusion norm, learned their school either had an inclusion norm or not, and were accountable to either their peer group, teachers, or nobody. Findings indicated, irrespective of age, that an inclusive school norm was less effective when the peer group had an exclusive norm and children were held accountable to their peers or teachers. These findings support social identity development theory (D. Nesdale, 2004, 2007), which expects both the in‐group peer and school norm to influence children's intergroup attitudes.  相似文献

We examined interactions between baseline hypothalamic–pituitary–adrenal (HPA) axis and parasympathetic nervous system (PNS) activity in relation to executive functions (EF) in a sample (n = 1,005) of children in low wealth, nonurban communities at age 48 months. Salivary cortisol and respiratory sinus arrhythmia (RSA) represented baseline HPA axis and PNS activity, respectively. The interaction between RSA and cortisol predicted EF such that children with either lower RSA and lower cortisol, or higher RSA and higher cortisol had higher EF scores. These findings suggest a potential compensatory relation in which the PNS and HPA axis counterbalance each other to support cognition.  相似文献

This study explored the relation between measures of emotional competence, behavioral regulation, and general social competence and African-American preschoolers' peer acceptance and popularity. These children came from both lower and middle income families. Data were collected in a short-term longitudinal study following children over the course of a school year. Gender, emotion knowledge, emotion regulation, and themes of violence in response to hypothetical situations of interpersonal conflict were strongly related to peer acceptance. The results are consistent with findings from middle-class Caucasian samples. The results also highlight the importance of potential influences of context and setting on children's peer status as well as the need for greater understanding of within- group variability with regard to these constructs. Given the growing evidence that peer relationships are related in important ways to children's school adjustment, understanding the development of positive peer relationships may help shed light on ways to help children achieve at more optimal levels in the school context.  相似文献

This 2-year longitudinal study examined, in a sample of Chinese children (initial M age = 11 years), the moderating effects of the peer group on relations between maternal supportive parenting and social and school adjustment. Data were collected from multiple sources including peer assessments, teacher ratings, school records, and maternal reports. It was found that whereas group prosocial-cooperative functioning strengthened the role of supportive parenting in helping children develop social and school competence, group antisocial-destructive functioning undermined the contributions of supportive parenting to children's social and academic achievement. The results indicated the significance of the peer group as a social context for socialization and development in Chinese children.  相似文献

The role of context in the development of child aggression was studied. The effects of peer aggregation and group composition on aggression development in intervention contexts and classroom contexts were compared using 71 elementary school children. We hypothesized that, due to peer group effects, group-trained children would benefit less from a social skills intervention program than individually trained children. We further hypothesized that children who transferred from special to regular education would show a change toward less aggression. This was hypothesized because of the relatively fewer accounts of negative peer-group effects in regular education. The results show that the social skills intervention program did not have differential effects for group-trained versus individually trained children. However, a change toward less aggression was found in children who transferred from special to regular education. We suggest that interventions toward decreasing child aggression might be more fruitful if the social context in which the children operate daily is considered.  相似文献

The effectiveness of a 12-week, small group emotional literacy (EL) intervention in reducing bullying behaviour in school was evaluated. Participants were 50 primary school pupils identified through peer nomination as engaging in bullying behaviours. The intervention was implemented in schools already engaged with a universal social and emotional learning initiative, including an anti-bullying component. Within schools, participants were randomly assigned to an intervention or a wait-list comparison group. Response to the intervention was found to be dependent on baseline levels of EL. Only children whose baseline level was low showed a significant reduction in peer-rated bullying behaviour. No effect of the intervention was detected on victimisation or adjustment scores, although positive changes in adjustment were associated with increased EL.  相似文献

The development of friendships and peer acceptance and their relation to children's emotional regulation and social-emotional behavior with others among a group of 3-5-year-old children was examined. Peer relationships and social-emotional skills were assessed early in the preschool year and peer relationships were assessed again late in the year. Preschool friendships were prevalent, moderately consistent across situations, and moderately stable over the course of the school year; peer acceptance also was moderately stable. Popularity of preschool children was related to their social behavior with peers both early and late in the school year but acceptance by the group was unrelated to children's emotion regulation. Number of mutual friendship choices was related to children's emotional regulation but not to social behaviors with peers late in the year. Acceptance by the peer group was related to number of mutual friends but there were some well-liked children who had no friends and disliked children who had friends. These results show the importance of popularity and early friendships in preschool classrooms. That is, these peer relationships are lasting and related to social and emotional development. Therefore, efforts to foster both group relations and mutual dyadic relationships should be included in preschool programming.  相似文献

The central question in this study is whether individual variability in children's cortisol levels and wellbeing at childcare can be explained by indices of quality of care and child characteristics. Participants were 71 children from childcare homes and 45 children from childcare centers in the age range of 20–40 months. In both types of settings equivalent measures and procedures were used. In home-based childcare, children experienced higher caregiver sensitivity, lower noise levels, and showed higher wellbeing compared to children in childcare centers. Caregiver sensitivity in home-based childcare – but not in center care – was positively associated with children's wellbeing. Additionally, children displayed higher cortisol levels at childcare than at home, irrespective of type of care. In home-based childcare, lower caregiver sensitivity was associated with higher total production of salivary cortisol during the day. In center-based childcare, lower global quality of care was associated with a rise in cortisol between 11 AM and 3 PM during the day. Quality of care is an important factor in young children's wellbeing and HPA stress reactivity.  相似文献

From a group of 75 children, originally selected as dyslectic on the basis of their reading and/or spelling problems relative to a total group of 1000 4.th grade children in the city of Trondheim, blood tests were obtained on 35 children. A control group of 45 children was drawn among the 1000 children. Among the 12 different hormones measured, significant differences came out on cortisol, triiodothyronine (T. 3), prolactin, and human growth hormone (HGH, somatotrophin) in boys and girls separately. A follow-up study of 22 dyslectic children from the same cohort gave results consistent with those obtained in the original study. The higher values of the dyslectic group on cortisol and prolactin may suggest the dyslectics to be in a stressful situation, possibly due to their language problems in school. The most striking difference, however, was the very low levels of HGH in the dyslectic group—to the extent that there was little overlap in the two distributions. This result was totally unexpected and is, in fact, opposite of what to be expected on the basis of at least short — time stress events. The results holds up when age and pubery development are controlled for.  相似文献

The potential role that children's classroom peer relations play in their school adjustment was investigated during the first 2 months of kindergarten and the remainder of the school year. Measures of 125 children's classroom peer relationships were obtained on 3 occasions: at school entrance, after 2 months of school, and at the end of the school year. Measures of school adjustment, including children's school perceptions, anxiety, avoidance, and performance, were obtained during the second and third assessment occasions. After controlling mental age, sex, and preschool experience, measures of children's classroom peer relationships were used to forecast later school adjustment. Results indicated that children with a larger number of classroom friends during school entrance developed more favorable school perceptions by the second month, and those who maintained these relationships liked school better as the year progressed. Making new friends in the classroom was associated with gains in school performance, and early peer rejection forecasted less favorable school perceptions, higher levels of school avoidance, and lower performance levels over the school year.  相似文献

The extent to which parent, school, and peer support differentially affected multiple domains of resilience was examined among 2,600 sixth, eighth, and tenth graders from an urban public school system who took part in a comprehensive survey of high-risk and adaptive behaviors. Structural equation modeling was used to specify the relation among seven domains of resilience and parent, school, and peer support among children who had been victimized by community violence, those who had witnessed such violence, and a no-exposure control group. Results upheld the validity of a multidimensional conceptualization of childhood resilience, and indicated that although both parent and school support factors were significantly positively associated with resilience in children who had been exposed to community violence, peer support was negatively associated with resilience in the domains of substance abuse and school misconduct/ delinquency. These results were most robust among victimized children, followed by children who had witnessed violence. Implications for social policy and community violence research are discussed.  相似文献

The purpose of this study was to further explore the linkage between children's early school attitudes and interpersonal features of the classroom, including children's relationships with classmates and their perceptions of these relationships. Participants included 102 kindergarten children (M age = 5.8 years) who were interviewed at the beginning and end of kindergarten to obtain measures of their school attitudes (i.e., school liking), classroom peer relationships (i.e., peer acceptance, mutual friendships), and peer relationship perceptions (i.e., perceived loneliness, peer support). Results showed that initial school liking was associated with all four measures of children's peer relationships; however, only the number of mutual friendships that children possessed in their classrooms predicted changes in school attitudes (gains) over time. Early school attitudes were linked to changes in children's peer perceptions; children who disliked school early in kindergarten were more likely to view classmates as unsupportive as the school year progressed. Results are discussed in terms of the potential impact that classroom peer relations may have on early school attitudes, and vice versa. Implications for educational policy are also considered.  相似文献

This study investigated the peer group as a context for the socialization of young adolescents' motivation and achievement in school. Social network analysis was used to identify peer groups of adolescents in middle school whose members regularly interacted with each other (N = 331). Actual reports from these peer group members were used to assess peer group characteristics. Multilevel analyses indicated that peer groups did socialize some academic characteristics, controlling for selection factors. Students' peer group context in the fall predicted changes in their liking and enjoyment of school (intrinsic value) and their achievement over the school year. Students' peer group context was unrelated to changes in their beliefs about the importance of school (utility value) or expectancies for success over the school year.  相似文献

This study examined associations among early adversity, diurnal cortisol, child sex, and caregiver sensitivity at age 6 months in relation to wheezing in children (47% male) followed to 30 months. Analyses included 676 mother-child dyads, 393 of whom completed an observational caregiver sensitivity measure. Participants were primarily ethnic minorities (42.7% Black, 25.4% Hispanic); 22.1% of children had ≥ 1 wheezing episode. Higher adversity was associated with increased wheeze frequency and blunted diurnal cortisol slope. The indirect effect of adversity on wheezing through cortisol slope was significant for females, but not males. Higher caregiver sensitivity was protective against wheezing for males, but not females, with high cortisol. Findings suggest complex associations among adversity, cortisol, child sex, and caregiver sensitivity in predicting wheezing.  相似文献

The association between child temperament characteristics and total diurnal saliva cortisol in 84 children (M = 2.3 years, SD = 0.6) attending out-of-home, center-based child care and 79 children (M = 2.0 years, SD = 0.5) attending at-home parental care was examined. Saliva samples were collected during two consecutive days, that is, Sunday and Monday, with four samples taken per day. While children higher in surgency had higher total diurnal cortisol production, we did not find evidence that temperament moderated the associations between child-care context and total diurnal cortisol. Negative affectivity and effortful control were not related to cortisol output. Our findings suggest that temperamental surgency may be associated with higher total cortisol production in early childhood across child-care settings.  相似文献

Children's evaluations of decision-making procedures were examined in applications in different social contexts. Seventy-two children evenly divided into three grade levels (grades 1 – 2, 3 – 4, 5 – 6) were administered a structured interview requiring them to evaluate three decision-making procedures (consensus, majority rule, and authority-based) embedded in three social contexts (peer group, family, and school classroom) and to select the most appropriate decision-making procedure for two specific decisions: one expected to pull for procedures emphasizing children's autonomous decision making, and one expected to pull for adult authority. Judgments of decision-making procedures at all grade levels did not show a heteronomous acceptance of adult authority but rather were influenced by social context and type of decision. In general, consensus was preferred in peer and family contexts and authority-based procedures were preferred for school decisions about curriculum. Older children were more likely than younger children to consider how children's limited knowledge and competence may constrain their autonomous decision making.  相似文献
