Maternal and child contributions to cortisol response to emotional arousal in young children from low-income, rural communities.

Relations of maternal and child characteristics to child cortisol reactivity to and recovery from emotional arousal were examined prospectively at approximately 7 months of age (infancy) and then again at approximately 15 months of age (toddlerhood). The sample was diverse and population based (N = 1,292 mother-infant dyads) and included families from predominantly low-income, rural communities. Maternal behavior, family income-to-need ratio and social advantage, and child temperament, attention, and mental development were assessed, and children's saliva was sampled before and after standardized procedures designed to elicit emotional arousal. Maternal engagement in infancy was associated with greater cortisol reactivity at the infancy assessment and with reduced overall cortisol level at the toddler assessment. Also at the toddler assessment, child attention, mental development, and temperamental distress to novelty were associated with increased cortisol reactivity and regulation, whereas temperamental distress to limitations and African American ethnicity were associated with reduced cortisol reactivity. Findings are consistent with prior work linking early caregiving to the development of the hypothalamic-pituitary-adrenal axis stress response system and with a conceptual model in which developing temperament is characterized by the interplay of emotional reactivity and the emergence of the ability to effortfully regulate this reactivity using attention.

The role of child adrenocortical functioning in pathways between interparental conflict and child maladjustment.

This study examined the interplay between interparental conflict and child cortisol reactivity to interparental conflict in predicting child maladjustment in a sample of 178 families and their kindergarten children. Consistent with the allostatic load hypothesis (McEwen & Stellar, 1993), results indicated that interparental conflict was indirectly related to child maladjustment through its association with individual differences in child cortisol reactivity. Analyses indicated that the multimethod assessment of interparental conflict was associated with lower levels of child cortisol reactivity to a simulated phone conflict between parents. Diminished cortisol reactivity, in turn, predicted increases in parental reports of child externalizing symptoms over a 2-year period. Associations between interparental conflict, child cortisol reactivity, and child externalizing symptoms remained robust even after demographic factors and other family processes were taken into account.

Examining infants' cortisol responses to laboratory tasks among children varying in attachment disorganization: Stress reactivity or return to baseline?

Cortisol is a hormone involved in mounting a stress response in humans. The evidence of stress reactivity among young children has been mixed, however. In the present study, the order of two laboratory tasks (i.e., Strange Situation and play) was counterbalanced, and home saliva samples were obtained. Saliva samples were also collected upon the children's arrival at the laboratory and at 40, 65, and 80 min after arrival. The authors examined changes in cortisol using piecewise hierarchical linear modeling, testing whether observed increases reflected a return to baseline or stress reactivity. An interaction between attachment disorganization and task emerged, such that disorganized infants showed increases in cortisol in response to the stressor compared with play, whereas organized infants did not show cortisol reactivity to either task. Implications for the buffering effects of maternal care on stress reactivity are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Inhibition and exuberance in preschool classrooms: Associations with peer social experiences and changes in cortisol across the preschool year.

Associations between behavioral inhibition and activity of the hypothalamic-pituitary-adrenocortical (HPA) system, a stress-sensitive neuroendocrine system indexed by salivary cortisol, have varied widely across studies. In the current study, we examined the role of peer social experiences in moderating patterns of association between inhibition/risk-aversion and cortisol reactivity. As expected based on previous research, preschool children (N = 165, 78 boys, 87 girls, 3.0–5.0 years) had significantly different social experiences in their preschool classrooms depending on temperament. Highly inhibited/risk-averse children were less socially integrated, less dominant, and less involved in aggressive encounters than both average and highly exuberant/risk-seeking children, but they were no more likely to be peer rejected. Highly exuberant children were more dominant, exhibited anger more often, and had friendships characterized by higher conflict. Cortisol levels fell from fall to spring for average and highly exuberant children but not for highly inhibited children. Unexpectedly, for highly inhibited children, having friends and being more dominant and popular than other highly inhibited children was associated with increasing cortisol levels over the school year. In contrast, highly exuberant children who were less socially integrated than other highly exuberant children maintained higher cortisol levels. Results indicate that the types of social experiences that affect stress-responsive biological systems may differ markedly for highly inhibited and highly exuberant children.

Forgivingness, relationship quality, stress while imagining relationship events, and physical and mental health.

In all, 39 participants (19 male, 20 female) were classified as either happy (n?=?19) or unhappy (n?=?20) with a relationship. Baseline salivary cortisol was measured. Participants imagined (for a 5-min duration) scenes typical of their relationship, and salivary cortisol was measured again. Participants in unhappy relationships had higher cortisol reactivity (indicating higher stress) following the imagery. Cortisol reactivity was predicted by relationship variables (high love and liking for the partner, high happiness with the relationship) and personality variables (high forgivingness, low trait anger). Personality had an indirect effect through the relationship variables. Physical health was predicted by personality variables. Mental health was predicted by both personality and relationship variables. Implications of these results for counseling health psychology are discussed.

Sensory modality, temperament, and the development of sustained attention: A vigilance study in children and adults.

Applying optimal stimulation theory, the present study explored the development of sustained attention as a dynamic process. It examined the interaction of modality and temperament over time in children and adults. Second-grade children and college-aged adults performed auditory and visual vigilance tasks. Using the Carey temperament questionnaires (S. C. McDevitt & W. B. Carey, 1995), the authors classified participants according to temperament composites of reactivity and task orientation. In a preliminary study, tasks were equated across age and modality using d= matching procedures. In the main experiment, 48 children and 48 adults performed these calibrated tasks. The auditory task proved more difficult for both children and adults. Intermodal relations changed with age: Performance across modality was significantly correlated for children but not for adults. Although temperament did not significantly predict performance in adults, it did for children. The temperament effects observed in children-specifically in those with the composite of reactivity-occurred in connection with the auditory task and in a manner consistent with theoretical predictions derived from optimal stimulation theory.

Blood lead (Pb) levels: Further evidence for an environmental mechanism explaining the association between socioeconomic status and psychophysiological dysregulation in children.

Objective: The authors recently reported that blood lead (Pb) was a significant mediator for the positive association between socioeconomic status (SES) and peripheral vascular responses to acute stress in children (B. B. Gump et al., 2007). The present study considers the possibility that Pb may also mediate an association between SES and cortisol responses to acute stress. Design: Early childhood Pb exposure was tested as a mediator for cross-sectional associations between SES and cortisol responses. Main Outcome Measures: The primary outcome was cortisol responses to acute stress in 9.5-year-old children (N = 108). Results: Lower family income was associated with significantly greater cortisol levels following an acute stress task. A mediational analysis confirmed that Pb was a significant mediator for this association. Conclusion: These results reaffirm the importance of considering the chemical environment as well as social and psychological environment when evaluating psychophysiological effects of low SES.

Autonomic functioning moderates the relations between contextual factors and externalizing behaviors among inner-city children.

Although previous research has identified various child-specific and contextual risk factors associated with externalizing behaviors, there is a dearth of literature examining child × context interactions in the prospective prediction of externalizing behaviors. To address this gap, we examined autonomic functioning as a moderator of the relation between contextual factors (i.e., neighborhood cohesion and harsh parental behaviors) and externalizing behaviors. Participants were an ethnic minority, inner-city sample of first through fourth grade children (N = 57, 50% male) and their primary caregivers who participated in two assessments approximately 1 year apart. Results indicated that baseline sympathetic functioning moderated the relation between (a) neighborhood cohesion and externalizing behaviors and (b) harsh parental behaviors and externalizing behaviors. Post-hoc probing of these interactions revealed that higher levels of neighborhood cohesion prospectively predicted (a) higher levels of externalizing behaviors among children with heightened baseline sympathetic functioning, and (b) lower levels of externalizing behaviors among children with attenuated baseline sympathetic functioning. In addition, among children with heightened baseline sympathetic functioning, higher levels of harsh parental behaviors prospectively predicted higher levels of externalizing behaviors.

Temperamental emotionality in preschool-aged children and depressive disorders in parents: Associations in a large community sample.

Researchers and clinicians have long hypothesized that there are temperamental vulnerabilities to depressive disorders. Despite the fact that individual differences in temperament should be evident in early childhood, most studies have focused on older youth and adults. We hypothesized that if early childhood temperament is a risk factor for depressive disorders, it should be associated with better established risk markers, such parental depression. Hence, we examined the associations of laboratory-assessed positive emotionality (PE), negative emotionality (NE), and behavioral inhibition (BI) with semistructured interview-based diagnoses of parental depressive disorders in a community sample of 536 3-year old children. Children with higher levels of NE and BI had higher probabilities of having a depressed parent. However, both main effects were qualified by interactions with child PE. At high and moderate (but not low) levels of child PE, greater NE and BI were associated with higher rates of parental depression. Conversely, at low (but not high and moderate) levels of child NE, low PE was associated with higher rates of parental depression. Child temperament was not associated with parental anxiety and substance use disorders. These findings indicate that laboratory-assessed temperament in young children is associated with parental depressive disorders; however, the relations are complex, and it is important to consider interactions between temperament dimensions rather than focusing exclusively on main effects.

Child temperament moderates the impact of parental separation on adolescent mental health: The trails study.

The potential effect of parental separation during early adolescence on adolescent externalizing and internalizing problems was investigated in a longitudinal sample of adolescents (n = 1274; mean age = 16.27; 52.3% girls). Pre-separation mental health problems were controlled for. Building on a large number of studies that overall showed a small effect of parental separation, it was argued that separation may only or especially have an effect under certain conditions. It was examined whether child temperament (effortful control and fearfulness) moderates the impact of parental separation on specific mental health domains. Hypotheses were derived from a goal-framing theory, with a focus on goals related to satisfying the need for autonomy and the need to belong. Controlling for the overlap between the outcome domains, we found that parental separation led to an increase in externalizing problems but not internalizing problems when interactions with child temperament were ignored. Moreover, child temperament moderated the impact of parental separation, in that it was only related to increased externalizing problems for children low on effortful control, whereas it was only related to increased internalizing problems for children high on fearfulness. The results indicate that person-environment interactions are important for understanding the development of mental health problems and that these interactions can be domain-specific.

Psychosocial correlates of childhood anxiety disorders

OBJECTIVE: This study explored psychosocial and "environmental" correlates of childhood anxiety disorders. The study examined relationships among parental psychiatric symptomatology, perceived family environment, temperament, and self-competence in children with a DSM-III-R anxiety disorder. METHOD: A community sample of third through sixth graders was screened initially for symptoms of test anxiety. Those with high and low scores were administered the Anxiety Disorders Interview Schedule for Children. Three groups (childhood anxiety disorder, test-anxious only, and normal controls) were identified and compared on the psychosocial variables. RESULTS: Children with an anxiety disorder had greater impairment on the indices of perceived self-competence and temperamental flexibility than controls, with the test-anxious children showing intermediate, yet significant, levels of disturbance. There was a trend for children with an anxiety disorder to describe their families as less promoting of independence than the other groups. Finally, measures of parental psychiatric symptomatology revealed more obsessive-compulsive symptoms for the fathers of both the anxiety disorder and test-anxious children compared with controls. CONCLUSIONS: Results are consistent with previous findings suggesting the familial transmission of anxiety disorders and recent speculations regarding a relationship between behavioral inhibition, environmental control, and anxiety. Further research may isolate psychosocial and family environmental factors as instrumental treatment targets in the management of childhood anxiety disorders.     

Juvenile male rape victims: is the level of post-traumatic stress related to personality and parenting?

OBJECTIVE: The purpose of this study was to assess the level of post-traumatic stress in juvenile male rape victims and to test for its relationships with perceived parental rearing and personality dimensions. METHOD: Fifteen subjects (mean age of 16 years) were recruited from a correctional camp for juvenile criminals in Arkhangelsk, Russia. They were investigated by means of the "Revised Impact of Event Scale," the "Child Self-Report Post-Traumatic Stress Reaction Index," the "Hospital Anxiety and Depression Scale," the "EMBU" (perceived parental rearing) and the "Temperament and Character Inventory" (TCI). RESULTS: The level of post-traumatic stress, in most cases moderate to high, correlated with the temperament dimensions of harm avoidance and reward dependence. As concerns parental rearing, the total level of post-traumatic stress reaction was negatively correlated with paternal emotional warmth and positively with paternal rejection. CONCLUSIONS: The experience of post-traumatic stress is influenced by temperamental characteristics as well as by perceived parental rearing practices. Assumingly, these factors also play a role in becoming a rape victim, which deserves further investigation.     

Attachment, temperament, and adrenocortical activity in infancy: A study of psychoendocrine regulation.

Examined the relations among adrenocortical stress reactivity, infant emotional or proneness-to-distress temperament, and quality of attachment in 66 infants tested at 9 and at 13 months. Performed the Louisville Temperament Assessment at 9 months and conducted the Strange Situation at 13 months. Adrenocortical activity was not associated with attachment classifications. Emotional temperament at 9 months was strongly correlated with emotional temperament at 13 months. There was also evidence that at both ages infants who were more prone to distress experienced greater increases in adrenocortical activity during the laboratory tests. Significantly, however, although both the Louisville Temperament Assessment and the Strange Situation involve maternal separation (a potent stimulant of the adrenocortical system in nonhuman primate infants), we noted only small elevations in cortisol, and these elevations were significant only at 9 months.

Skin conductance level reactivity moderates the association between harsh parenting and growth in child externalizing behavior.

Skin conductance level reactivity (SCLR) was examined as a moderator of the association between harsh parenting at age 8 years and growth in child externalizing behavior from age 8 to age 10 (N = 251). Mothers and fathers provided reports of harsh parenting and their children's externalizing behavior; children also provided reports of harsh parenting. SCLR was assessed in response to a socioemotional stress task and a problem-solving challenge task. Latent growth modeling revealed that boys with higher harsh parenting in conjunction with lower SCLR exhibited relatively high and stable levels of externalizing behavior during late childhood. Boys with higher harsh parenting and higher SCLR exhibited relatively low to moderate levels of externalizing behavior at age 8, but some results suggested that their externalizing behavior increased over time, approaching the same levels as boys with higher harsh parenting and lower SCLR by age 10. For the most part, girls and boys with lower harsh parenting were given relatively low and stable ratings of externalizing behavior throughout late childhood. Results are discussed from a developmental psychopathology perspective with reference to models of antisocial behavior in childhood. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Down's syndrome temperament and maternal response to descriptions of child behavior.

Administered a behavioral style questionnaire (BSQ) to the mothers of 23 3–6 yr old Down's syndrome children to determine the temperament characteristics of their child and interviewed them with a parental learning theory scale (PLTS) that asked how they would handle certain specified child behaviors. Results show that mothers with temperament rated as easy responded to the PLTS situations with more direct teaching responses and with less verbal expression of negative emotions than mothers of more difficult children. In addition, there were significant associations between maternal PLTS response and the activity, rhythm, approach, adaptability, and mood dimensions of the BSQ.

Correction to Beaulieu and Sylvie Normandeau (2011).

Reports an error in "Prédicteurs des pratiques parentales: Cognitions sociales parentales et comportement des enfants TDAH" by Marie-Christine Beaulieu and Sylvie Normandeau (Canadian Journal of Behavioural Science/Revue canadienne des sciences du comportement, Advanced Online Publication, Jul 25, 2011, np). There was an error in the English abstract. This error is corrected in the correction. (The following abstract of the original article appeared in record 2011-15455-001.) The purpose of this study was to examine the association between parental social cognitions (parental causal attributions, parental self-efficacy) and the behavioural characteristics of their child (ADHD subtypes, comorbidity, oppositional and anxiety/shy symptoms). Participants were 110 families with a child with ADHD (ADHD-I : n = 31, ADHD-H : n = 11, ADHD-C : n = 68). Multiple regressions show that parental self-efficacy is associated with more use of appropriate discipline, praise and incentives, positive verbal discipline, and less use of harsh and inconsistent discipline and physical punishment. Results also show that parental causal attributions for the child's misbehaviour to their own efforts are a predictor of positive verbal discipline whereas parents' causal attributions for the child's misbehaviour to the child's lack of efforts are a predictor of harsh and inconsistent discipline. Parents' perception of their child's oppositional symptom is a predictor of appropriate discipline and positive verbal discipline. Finally, children's comorbidity is a predictor of harsh and inconsistent discipline. The findings of this study highlight the importance of parental self-efficacy, because from all the variables studied, it shows the strongest association with positive and negative parenting practices. No association between ADHD subtype and parenting practices were observed. Implications of these results are explored in the discussion.

Respective influence of occupational and personal factors on respiratory function in dairy farmers

OBJECTIVE: This study proposes to test the hypothesis that early loss of a parent, coupled with poor quality family relationships, would result in long-term increased cardiovascular and cortisol reactivity to stress. METHODS: Subjects included 30 university students who lost one parent before age 16, and 31 control subjects. Blood pressure (BP) was measured continuously during 5-minute baseline and recovery periods, and during each of 2 tasks--viewing a 7-minute video clip depicting the death of a parent, and giving a 3-minute impromptu speech (1-hour rest between tasks). Salivary cortisol samples were collected immediately before each task, and at 5 and 20 minutes posttask. Quality of family relationships (FR) was measured using the Moos Family Environment Scale. RESULTS: Repeated-measures analysis of covariance revealed significant main effects on BP of both parental loss and FR for both tasks (all p values < .05) such that subjects who lost a parent or reported poor quality FR showed higher BP across all periods. The loss by FR by period interaction was not significant. An FR by period interaction was found for cortisol during the movie, in which poor quality FR subjects showed increased cortisol, whereas all others showed decreases. A loss by period interaction was found for cortisol during the speech, in which cortisol increased in loss subjects and decreased in non-loss subjects. CONCLUSIONS: These findings indicate that both childhood loss of a parent and poor quality of caretaking are associated with long-term increases in BP and altered neurohormonal responses to stress.     

The import of the cortisol rise in child care differs as a function of behavioral inhibition.

Children of ages 3 to 4.5 years (N = 107; 45 boys, 62 girls) were studied twice, 6 months apart, to examine whether the cortisol rise in child care at Time 1 (T1) was associated with (a) changes in anxious, vigilant behavior from T1 to Time 2 (T2) and (b) higher internalizing symptoms at T2. Controlling for measures of home environment and child care quality at T1, as well as for cortisol activity at T2, we obtained results indicating that behavioral inhibition moderated the associations between the rise in cortisol at T1 and child outcomes at T2 (i.e., anxious, vigilant behavior and internalizing symptoms). For both outcomes, the rise in cortisol at T1 became more positively predictive at increasing levels of behavioral inhibition. Specifically, at higher levels of behavioral inhibition, children with larger T1 cortisol increases expressed more internalizing symptoms than did children at lower levels of behavioral inhibition; in contrast, for those with low cortisol activity at T1, children with higher levels of inhibition expressed fewer internalizing symptoms than did children at lower levels of inhibition. In addition, children with higher levels of behavioral inhibition and lower cortisol activity at T1 exhibited reductions in anxious, vigilant behavior from T1 to T2, whereas at lower levels of behavioral inhibition, variations in the T1 cortisol rise bore no relation to changes in this behavior. These results suggest that the rise in cortisol at child care may have differential predictive value as a function of behaviorally inhibited temperament.

Interparental conflict and the children of discord and divorce.

Reviews the literature on the relation between marital turmoil (i.e., discord and divorce) and behavior problems in children. Some variables affecting this relationship include type of marital turmoil, form of the child's behavioral response, sex differences, age effects, parental buffering, and effects of parental psychopathology. Children's conflict responses in both broken and intact families are discussed, and the author notes that since parental conflict does not terminate with divorce, the conflict responses found in children of divorce are often similar to those of children from discordant, intact marriages. Studies have found that marital discord is more strongly related to boys' than to girls' maladaptive behavior, but age has not been shown to alter the reaction. Hypotheses about how marital turmoil produces childhood disorders include (a) disruption of attachment bonds, (b) modeling, (c) altered discipline practices, and (d) stress models.

Mother-adolescent physiological synchrony in naturalistic settings: Within-family cortisol associations and moderators.

In this study, the authors examined parent-adolescent cortisol associations in 45 families with adolescent children (24 girls; M age = 15.78 years, SD = 1.44 years). Family members’ salivary cortisol levels were measured seven times a day on 2 typical weekdays. Family members provided reports of demographic and health variables, and adolescents rated parent-child relationship characteristics. After accounting for the effects of time of day and relevant demographic and health control variables on cortisol levels, hierarchical linear models indicated the presence of significant covariation over time in mother-adolescent cortisol (i.e., physiological synchrony). Furthermore, moderating tests revealed that mother-adolescent cortisol synchrony was strengthened among dyads characterized by mothers and adolescents spending more time together, and in families rated higher on levels of parent-youth shared activities and parental monitoring or supervision. Analysis of momentary characteristics indicated that maternal presence at the time of cortisol sampling lowered adolescent cortisol levels but did not account for mother-adolescent cortisol synchrony. Within-family physiological synchrony was amplified in momentary contexts of elevated maternal negative affect and elevated adolescent negative affect.
