The study examined growth in effortful control (executive control, delay ability) in relation to income, cumulative risk (aggregate of demographic and psychosocial risk factors), and adjustment in 306 preschool-age children (50% girls, 50% boys) from families representing a range of income (29% at- or near-poverty; 28% lower-income; 25% middle-income; 18% upper-income), with 4 assessments starting at 36–40 mos. Income was directly related to levels of executive control and delay ability. Cumulative risk accounted for the effects of income on delay ability but not executive control. Higher initial executive control and slope of executive control and delay ability predicted academic readiness, whereas levels, but not growth, of executive control and delay ability predicted social competence and adjustment problems. Low income is a marker for lower effortful control, which demonstrates additive or mediating effects in the relation of income to children’s preschool adjustment.

This study tested the hypothesis that the effects of income and cumulative risk on the development of effortful control during preschool would be mediated by parenting. The study utilized a community sample of 306 children (36–40 months) representing the full range of family income, with 29 percent at or near poverty and 28 percent lower income. Two dimensions of effortful control (executive control and delay ability) were assessed at four time points, each separated by nine months, and growth trajectories were examined. Maternal warmth, negativity, limit setting, scaffolding, and responsiveness were observed. Above the effects of child cognitive ability, income, and cumulative risk, scaffolding predicted higher initial levels of executive control that remained higher across the study, and limit setting predicted greater gains in executive control. Parenting did not predict changes in delay ability. Significant indirect effects indicated that scaffolding mediated the effects of income and cumulative risk on growth in executive control. The findings suggest that parenting behaviors can promote effortful control in young children and could be targets of prevention programs in low‐income families.

DBT group skills training may be efficacious, acceptable, and feasible for treating ADHD among college students. A larger randomized trial is needed for further evaluation.

Context The term temperament refers to a biologically based predilection for a distinctive pattern of emotions, cognitions, and behaviours first observed in infancy or early childhood. High reactive infants are characterized at 4 months by vigorous motor activity and crying in response to unfamiliar visual, auditory, and olfactory stimuli, whereas low reactive infants show low motor activity and low vocal distress to the same stimuli. High reactive infants are biased to become behaviorally inhibited in the second year of life, defined by timidity with unfamiliar people, objects and situations. In contrast, low reactive infants are biased to develop into uninhibited children who spontaneously approach novel situations. Objective To examine whether differences in the structure of ventromedial or orbitofrontal cerebral cortex at age 18 years are associated with high or low reactivity at 4 months of age. Design Structural MRI in a cohort of 18-year olds enrolled in a longitudinal study. Temperament was determined at 4 months of age by direct observation in the laboratory. Setting Athinoula A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital Participants 76 subjects who were high reactive or low reactive infants at 4 months of age. Main Outcome Measures Cortical thickness Results Adults with a low reactive infant temperament, compared with those categorized as high reactive, showed greater thickness in left orbitofrontal cortex. Subjects categorized as high reactive in infancy, compared with those previously categorized as low reactive, showed greater thickness in right ventromedial prefrontal cortex. This is the first demonstration that temperamental differences measured at 4 months of age have implications for the architecture of human cerebral cortex lasting into adulthood. Understanding the developmental mechanisms that shape these differences may offer new ways to understand mood and anxiety disorders as well as the formation of adult personality.

Objective: Bidirectional associations between child temperament (fear, frustration, positive affect, effortful control) and parenting behaviors (warmth, negativity, limit setting, scaffolding, responsiveness) were examined as predictors of preschool-age children’s adjustment problems and social competence. Method: Participants were a community sample of children (N = 306; 50% female; 64% European American) and their mothers. Observational measures of child temperament and parenting were obtained using laboratory tasks at two time points (children’s ages 36 and 54 months). Teacher-reported adjustment measures were collected at the first and third time points (children’s ages 36 and 63 months). Results: Cross-lagged analyses were performed to examine whether child temperament and parenting predict changes in one another, whether they each contribute independently to children’s adjustment, and whether these transactional relations account for adjustment outcomes. Maternal negativity at 36 months predicted increases in child frustration at 54 months. Maternal negativity and child effortful control predicted decreases in each other from 36 to 54 months. Maternal warmth predicted increases in child effortful control over time. Child frustration, child effortful control, maternal warmth, and maternal negativity at 54 months each independently predicted child adjustment problems at 63 months, controlling for problems at 36 months. Child executive control at 54 months predicted increases in child social competence at 63 months. Conclusions: The findings suggest that temperament and parenting have independent and additive effects on preschool-age child adjustment, with some support for a bidirectional relation.

Interactions between reactive and regulatory dimensions of temperament may be particularly relevant to children’s adjustment but are examined infrequently. This study investigated these interactions by examining effortful control as a moderator of the relations of fear and frustration reactivity to children’s social competence, internalizing, and externalizing problems. Participants included 306 three-year-old children and their mothers. Children’s effortful control was measured using observational measures, and reactivity was assessed with both observational and mother-reported measures. Mothers reported on children’s adjustment. Significant interactions indicated that children with higher mother-reported fear or higher observed frustration and lower executive control showed higher externalizing problems whereas children with higher observed fear and higher delay ability demonstrated lower externalizing problems. These results highlight effortful control as a moderator of the relation between reactivity and adjustment, and may inform the development of interventions geared toward the management of specific negative affects.

The effects of low income on children's adjustment might be accounted for by disruptions to hypothalamic–pituitary–adrenal (HPA)-axis activity and to the development of effortful control. Using longitudinal data and a community sample of preschool-age children (N = 306, 36–39 months) and their mothers, recruited to over-represent low-income families, we explored the associations among diurnal cortisol levels and effortful control, and we tested a model in which diurnal cortisol and effortful control account for the effects of family income on child adjustment. Continuous indicators of morning cortisol level and diurnal slope, as well as dichotomous indicators reflecting low morning levels and flat diurnal slope, were examined as predictors of rank-order changes in two dimensions of effortful control, executive control and delay ability. Low income was related to a flat diurnal cortisol slope, and above the effects of family income, a flat diurnal cortisol slope predicted lower social competence. Low morning cortisol level predicted smaller gains in executive control and higher total adjustment problems. Further, delay ability predicted lower adjustment problems above the effects of income and diurnal cortisol levels. The results suggest that HPA-axis dysregulation and effortful control contribute additively to children's adjustment.

This study tested child characteristics (temperamental executive control and negative reactivity) and maternal characteristics (parenting behaviors and maternal depressive symptoms) as predictors of a mother's emotion-related socialization behaviors (ERSBs). Further, parenting behaviors and ERSBs were examined as predictors of children's emotion knowledge, social competence, and adjustment problems. ERSBs and children's emotion knowledge were tested as mediators of the effects of child and parent characteristics on adjustment. A community sample (N ϭ 306) of mothers and children (36 -40 months at T1) were assessed 4 times, once every 9 months, and assessments included maternal reports of depressive symptoms, observed temperament, observational ratings of general parenting at T1, maternal report of ERSBs at T1 & T2, behavioral measures of emotion knowledge at T3, and teacher ratings of children's adjustment at T4. There were no predictors of ERSBs above prior levels. Higher executive control and lower maternal depressive symptoms predicted greater child emotion knowledge, highlighting the roles of maternal and child contributors to emotion knowledge. Greater emotion knowledge and positive affective quality in parenting predicted children's adjustment, with emotion knowledge mediating the effects of executive control on children's adjustment. In addition, lower levels of maternal supportive ERSBs predicted greater adjustment problems. This study highlights the roles of key variables in Eisenberg, Cumberland, and Spinrad's (1998) heuristic model of emotion socialization and the importance of emotion socialization and emotion knowledge in children's adjustment.
