Predicting toddler temperamental approach-withdrawal: Contributions of early approach tendencies, parenting behavior, and contextual novelty

Research suggests that temperamental approach-withdrawal is subject to parenting influences, but few studies have explored how specific parenting behaviors and contextual novelty contribute to the observed pattern of effects. The present study examined associations between infant temperamental approach, mother behavior while introducing novel objects (12months) and temperamental approach-withdrawal in toddlerhood (18months) in a sample of 132 infants (68 males). Maternal positive affect predicted more toddler approach-withdrawal for high-approach infants and maternal stimulation predicted less toddler approach-withdrawal for low-approach infants; however, these patterns varied with intensity of novelty in both parenting and toddler outcome contexts. Thus, maternal behavior may lead to stronger associations between earlier and later measures of approach-withdrawal; however, these effects are tied to contexts of measurement.

Linking Maternal Socialization of Positive Emotions to Children’s Behavioral Problems: The Moderating Role of Self-Control

Little is known about how parents socialize children’s positive affect regulation during late childhood. Consequently, we examined how mothers’ reported responses to their children’s (aged 7–12 years) positive emotions were linked to children’s behavioral problems and how children’s self-control moderated these associations. Our results indicated that maternal encouragement of positive emotions predicted fewer externalizing behaviors, but only for youth with lower self-control. Maternal explanation about their children’s positive emotions was unrelated to youth’s behavioral problems. Lastly, maternal dismissing responses to their children’s positive emotions (i.e., reprimanding responses and discomfort) were related to more externalizing and internalizing in youth, and these effects were not dependent on the children’s self-control. The current study adds to the limited research on positive affect socialization and offers some evidence that youth’s self-control may serve as a vantage-sensitivity factor in the association between maternal positive affect socialization and youth adjustment.

Maternal positive affect mediates the link between family risk and preschoolers' positive affect.

The present study sought to further specify conceptual models of youth positive affect (PA) by examining mothers' observed PA as a mediator of the relation between family risk (based on maternal reports of demographic factors) and children's PA in a sample of 82 mothers (M = 31.25 years, SD = 6.16) and their preschool-aged children (M = 3.51 years, SD = .49, 63.00% boys). Results yielded a significant, negative correlation between family risk and child PA. Mediation analyses indicated that family risk was related to child PA through its effects on maternal PA, even after controlling for maternal depression symptoms. Findings suggest that family risk and maternal PA are important factors to consider in understanding preschoolers' PA development. Identifying children at risk for developing PA difficulties can aid in the implementation of prevention and intervention strategies for promoting young children's PA specifically, and their psychosocial functioning more broadly.

Effects of socioeconomic status on maternal and child positive behaviors in daily life among youth with asthma.

Socioeconomic disadvantage is associated with poorer behavioral and emotional outcomes in children with asthma. This study investigated the associations between maternal income and education and naturalistically observed behaviors and affect during everyday parent-child interactions. 53 predominantly low-income youth with asthma, aged 10-17 years, wore a naturalistic event-sampling device, the Electronically Activated Recorder, for 4 days to assess mother and child positive behaviors and affect in daily life. Maternal education, but not income, was positively associated with child positive behaviors, displays of mother and child positive affect, and increased maternal responsiveness. Maternal positive affect and maternal responsiveness mediated the effect of maternal education on child positive affect. Our findings suggest that maternal education has an important influence on the socioemotional adjustment of youth with asthma and point to the importance of investigating the independent influence of socioeconomic status components on everyday parent-child interactions.

Maternal positive affect over the course of pregnancy is associated with the length of gestation and reduced risk of preterm delivery

ObjectiveThe association between maternal psychological state during pregnancy and birth outcomes is well established. The focus of previous studies has been on the potentially detrimental consequences of maternal stress on pregnancy and birth outcomes, particularly shortened gestation and increased risk of preterm birth. Despite a growing literature linking positive affect with favorable health outcomes this construct has received little attention in the context of pregnancy. Therefore, in the current study, we tested the hypothesis that maternal positive affect during pregnancy is associated with beneficial consequences in terms of increased length of gestation and reduced risk of preterm birth above that of the absence of stress. MethodsIn 169 pregnant women maternal positive affect and perceived stress were serially assessed at 15.2±0.9weeks (T1; mean±SD), 19.7±0.9weeks (T2) and 30.7±0.7weeks (T3) gestation. Pregnancy and birth outcomes were abstracted from the medical record. ResultsHigher maternal positive affect and a steeper increase in maternal positive affect over pregnancy were positively associated with length of gestation (p<.05) and reduced risk of preterm delivery (p<.01), whereas maternal perceived stress was not significantly associated with shorter length of gestation (p>.10). ConclusionsThese findings suggest that maternal positive affect may be beneficial for outcomes related to the length gestation, and that this effect cannot be accounted for by the lower stress levels associated with higher positive affect. Interventions to increase maternal positive affect may be beneficial for fetal development.

Attention bias in youth: Associations with youth and mother's depressive symptoms moderated by emotion regulation and affective dynamics during family interactions

Recent research has highlighted the potential role of attention bias for emotional stimuli as a possible cognitive risk factor for depression in youth. However, differences in youth emotion regulation or maternal affect may moderate the association between maternal and youth depression and youth attention biases. The current study investigated the relationship between maternal and youth depressive symptoms and youth (aged 11–17 years) attention bias for sad and happy faces in 59 mother–youth dyads, examining whether positive and negative maternal affect observed during structured interaction tasks or youth emotion regulation tendencies moderated associations between maternal and youth depression and attention biases. Youth suppression interacted with maternal and youth depression to predict sad attentional biases in youth, while maternal positive affect interacted with maternal depression to predict happy attention biases in youth.

Infant developmental outcomes following prenatal exposure to antidepressants, and maternal depressed mood and positive affect

BackgroundPrenatal exposure to serotonin reuptake inhibitor (SRI) antidepressants has been associated with delays in early developmental milestones, but there remains uncertainty. Even among a subset of studies examining the Bayley Scales of Infant Development (BSID), some have reported normal mental and psychomotor development while others have suggested a delay in motor development. Given an increasing number of infants exposed to SRIs, furthering our understanding of the possible developmental implications of SRI exposure in utero is critical. AimsTo examine the effects of prenatal serotonin reuptake inhibitor exposure and maternal mood on infant developmental outcomes at 10months of age. Study designProspective study of mothers and their 10-month-old infants. SubjectsWe examined 31 mother–child pairs exposed prenatally to SRIs and 52 mother–child pairs who were nonexposed. Outcome measureThe Bayley Scales of Infant Development (third edition) scores. ResultsInfants exposed prenatally to SRIs scored significantly lower than nonexposed infants on gross motor (P=0.03), social–emotional (P=0.04) and adaptive behavior (P=0.05) subscales of the BSID-III, controlling for pre- and postnatal maternal depressed mood, smoking and alcohol use during pregnancy. No significant differences in any of the BSID-III subscales were observed between infants exposed and infants nonexposed to pre and postnatal maternal depressed mood (P>0.05). Increased levels of maternal positive affect at 10months predicted increased social–emotional scores (P=0.03). ConclusionsInfants prenatally exposed to SRIs score significantly lower on the gross motor, social–emotional and adaptive behavior subscales of the BSID-III, and this was not explained by underlying maternal depression.

Infancy predictors of preschool and post-kindergarten executive function.

Little is known about factors that promote optimal development of executive function (EF) skills. The focus of this study was associations among early maternal behaviors, infant frontal brain electrical activity, and child EF at age 4 and following kindergarten. Infant frontal electroencephalogram was collected from 56 infants at 10 months of age and maternal positive affect was observed. Children completed EF measures in the research laboratory at age 4; parental-reported EF was obtained following children's kindergarten year. Maternal positive affect and infant frontal brain electrical activity measured when the children were 10 months jointly and uniquely predicted both preschool and post-kindergarten EF. Findings suggest parenting behavior and brain development in infancy are precursors of later self-regulatory EF abilities.

Preterm infants who are prone to distress: differential effects of parenting on 36‐month behavioral and cognitive outcomes

The differential susceptibility (DS) model suggests that temperamentally prone-to-distress infants may exhibit adverse outcomes in negative environments but optimal outcomes in positive environments. This study explored temperament, parenting, and 36-month cognition and behavior in preterm infants using the DS model. We hypothesized that temperamentally prone to distress preterm infants would exhibit more optimal cognition and fewer behavior problems when early parenting was positive; and less optimal cognition and more behavior problems when early parenting was less positive. Participants included 109 preterm infants (gestation <37 weeks) and their mothers. We assessed neonatal risk and basal vagal tone in the neonatal intensive care unit; infant temperament and parenting interactions at 9 months post-term; and child behavior and cognitive skills at 36 months post-term. Hierarchical regression analyses tested study hypotheses. Temperamentally prone-to-distress infants exhibited more externalizing problems if they experienced more critical parenting at 9 months (β = -.20, p < 0.05) but fewer externalizing problems with more positive parenting. Similarly, variations in maternal positive affect (β = .25, p < .01) and intrusive behaviors (β = .23, p < .05) at 9 months predicted 36-month cognition at high but not at low levels of infant temperamental distress. Higher basal vagal tone predicted fewer externalizing problems (β = -.19, p < .05). Early parenting behaviors relate to later behavior and development in preterm infants who are temperamentally prone to distress, and neonatal basal vagal tone predicts subsequent externalizing behaviors. These findings suggest that both biological reactivity and quality of caregiving are important predictors for later outcomes in preterm infants and may be considered as foci for developmental surveillance and interventions.

The impact of borderline personality pathology on mothers' responses to infant distress.

This study sought to extend extant research on the association between borderline personality (BP) pathology and at-risk parenting by examining the dynamic nature of parenting in response to infant distress in mothers with and without clinically relevant levels of BP pathology. Findings revealed that mothers with clinically relevant levels of BP pathology were less likely than those without BP pathology to display positive affect in response to infant distress. There were no differences in the overall likelihood of insensitive parenting behaviors as a function of BP pathology, either in general or in response to infant distress. However, consistent with literature emphasizing the transactional nature of parent-child relationships, findings revealed that the likelihood of insensitive parenting behaviors among mothers with clinically relevant levels of BP pathology changed over time, increasing significantly as infant distress persisted for longer durations (a pattern not present for mothers without BP pathology). Moreover, maternal responses to infant distress were found to influence infant distress, with the likelihood of infant distress decreasing after maternal positive affect and increasing after maternal insensitive behaviors. The implications of findings for understanding the mechanisms of risk for children of mothers with BP pathology, as well as the transactional nature of mother-infant relationships in general, are discussed.

Infant physiological regulation and maternal risks as predictors of dyadic interaction trajectories in families with a preterm infant.

This longitudinal study examined predictors of rates of growth in dyadic interaction quality in children born preterm who did not experience significant neurological findings during neonatal intensive care unit (NICU) hospitalization. Multiple methods were used to collect data from 120 preterm infants (48% girls, 52% boys) and their mothers. Infant heart rate variability (HRV), gestational age, neonatal health, feeding route, and maternal socioeconomic (SES) risks were assessed at NICU discharge (mean of 36 weeks postconception). Mother-child interactions were observed at 4, 9, 16, and 24 months postterm and analyzed with hierarchical linear modeling. On average, children's quality of play, interest, and attention increased over time while their dysregulation and irritability decreased, whereas average maternal positive affect and involvement declined in quality (ps < .05), although there was individual variation in rates of change. Mothers of infants with higher postfeeding HRV (i.e., vagal regulation) exhibited less decrease in positive affect and involvement between 4 months and 24 months, compared with mothers of infants with lower HRV (p < .05). Although infants with higher postfeeding HRV showed less positive affect and communication at 4 months, they exhibited significantly greater increases in positive affect and social competence and decreases in dysregulation and irritability between 4 months and 24 months, compared with infants with lower HRV (ps < .05). Dyads experiencing more SES risks showed less optimal interactions at 4 months; this difference remained as children grew older (ps < .05). Results have implications for our understanding of social development in preterm infants.

Neonatal maternal separation alters reward-related ultrasonic vocalizations in rat dams

We examined the effects of brief or long durations of repeated maternal separation (MS) on ultrasonic vocalizations (USVs) in rat dams. 50-kHz USVs putatively identified as maternal in origin were emitted only immediately after pups were returned following MS. Maternal USV emission also depended on separation duration and pup age. Given that 50-kHz USVs are emitted in response to rewarding stimuli, MS may induce duration-dependent effects on maternal positive affect.

The Mediating Effects of Parenting Behaviors on Maternal Affect and Reports of Children’s Behavior

Parenting behaviors have received ample support as a mediator of the relationship between maternal affect and child behavior problems. The majority of these research efforts were based on a uni-dimensional conceptualization of maternal mood, even though decades of theory and research suggest that mood is multidimensional. We examined the mediating role of parenting behaviors on positive affect (PA) and negative affect (NA) and reports of child behavior problems. Evidence for mediation was demonstrated for both PA and NA for children in early to middle childhood. Consistent with the positive psychology movement, our results suggest that maternal PA plays an important role in parents’ utilization of effective parenting behaviors. Implications for clinical intervention and future research are discussed.

Maternal correlates of health status in adolescents with inflammatory bowel disease

Objective: People with inflammatory bowel disease (IBD) manifest great variability in health status, but little research has examined correlates of this variability, especially among adolescents with IBD. This study examined family dysfunction, maternal physical symptoms and maternal positive affect (PA) as correlates of variability in depression, pain/fatigue, functional disability and bowel movement frequency among adolescents with IBD. We also tested whether these relationships were independent of maternal negative affect (NA). Methods: Participants were 62 adolescents with IBD (36 with Crohn's disease (CD) and 26 with ulcerative colitis [UC]) and their mothers. Mothers completed measures about the family and themselves, and adolescents provided health status measures. Results: Controlling for the duration since diagnosis, we found that family dysfunction correlated significantly and positively with bowel movement frequency of the adolescent (partial r=.27), and mother's PA correlated inversely with adolescent's depression (partial r=−.30) and functional disability (partial r=−.28). These relationships remained significant after controlling for maternal NA. Maternal symptoms were not related to the adolescent's health status. Analyses indicated that relationships did not differ for the two IBD subtypes. Discussion: Family dysfunction and maternal PA appear to account for some of previously unexplained variance in the health status of adolescents with IBD. Family interventions should be explored to determine whether these familial and maternal factors influence the health of the adolescent, and whether improving family functioning can lead to health improvements in the children.

Parenting and child behavioral adjustment in early childhood: a quantitative genetic approach to studying family processes.

The aim of this study was to examine environmental and gene-environment processes linking parenting (i.e., affect, control, responsiveness) and preschool children's behavioral adjustment difficulties (e.g., noncompliance, conduct problems) by using bivariate genetic analyses of parents' and observers' ratings. The sample included 120 identical and same-sex fraternal twin pairs (M age = 43 months). Data sources included in-home observations, interviews, and parents' reports. Observers' ratings of children's difficult behaviors included shared and nonshared environmental variance. In contrast, parents' ratings of children's conduct problems showed genetic and nonshared environmental variance. Observer-rated maternal behavior included shared and nonshared environmental variance, although maternal responsiveness also included child genetic variance. Parent self-reported negative and positive affect included shared and nonshared environment as well as child genetic variance. There was no evidence for gene-environment interaction or dominance. Higher levels of difficult behavior and conduct problems covaried with higher levels of maternal negative affect and control and lower levels of maternal positive affect and control. Shared environmental mediation of these correlations was found for observations, whereas genetic and nonshared environmental mediation was found for parents' ratings. In general, estimates of shared environmental variance and mediation were greatest for observational data, and estimates of child genetic variance and mediation were greatest for parent-rated data. The implications of this pattern of findings for genetic research on family processes are discussed.

Mothers' affective behavior with infant siblings: stability and change.

To evaluate within-family differences in maternal affective behavior toward siblings, face-to-face interactions were observed between 39 mothers and their firstborn and second-born infants at 2 months of age. Mother and infant affect was coded on a 1-s time base with behavioral descriptors. Mothers were more positive with second-born infants, and second-born infants were more positive than were firstborns. The siblings' affective behaviors were unrelated, but maternal positive affect was both moderately stable between siblings and correlated with each infant's affect. Thus, in the context of stable individual differences in maternal positive affect, siblings experienced unique affective interactions with their mothers as early as 2 months.

Attachment classification and infant responsiveness during interactions

The relation between infant responsiveness during interactions and attachment classification was investigated. Sixty-two 12- to 16-month-old infants classified as secure, avoidant, and ambivalent in the Strange Situation were seen during a 9-min mother-infant teaching task. Infant responsiveness was defined as the difference between base rate occurrence of infant behaviors and the probability of infant behavior given a preceeding maternal behavior. Different patterns of infant responsiveness emerged for the three groups of dyads. The positive behavior of infants in secure dyads was elicited by, and negative behavior was suppressed by, maternal positive and helping behavior. The positive behavior of avoidant infants was elicited by positive maternal behavior and was suppressed by maternal positive affect. The positive behaviors of ambivalent infants were elicited by maternal positive, helping, and interfering-coercive behaviors. These results indicate that patterns of responsiveness, rather than absolute proportions of behaviors, may discriminate among infants in the three attachment classifications and may provide clues as to the relational objectives pursued by infants as a function of their interactive history.

Relations between parent–child affect and synchrony and cognitive outcome at 5 years of age

AbstractThis investigation involved the longitudinal assessment of 30 preterm and 39 full‐term infants from 2 to 5 years of age. Measures of cognitive outcome at 2 and 5 years of age and mother‐child dyadic synchrony and affect during free‐play interaction were obtained at 5 years of age. Correlational and regression analyses indicated that 5‐year cognitive outcome was predicted by 2‐year cognitive status, mother education, and 5‐year dyadic interaction. In addition, 5‐year maternal positive affect contributed independently to children's cognitive status at age 5, above and beyond the contributions of early cognitive status and maternal education. Also, affect and synchrony interacted in predicting lower cognitive abilities. Findings are discussed in relation to the importance of maternal affect and synchronous interactions in transactional explanations of development during early childhood.

Childrearing history, marital quality, and maternal affect: Intergenerational transmission in a low-risk sample

AbstractIn order to test the hypothesis that the relation between childrearing history and parental behavior varies as a function of marital quality, retrospectively reported childrearing histories obtained from 92 middle- and working-class mothers-to-be in the last trimester of pregnancy were used to predict maternal positive and negative affect when children were 3-years-old. As anticipated on the basis of findings from high-risk samples, the intergenerational transmission process appeared to vary as a function of marital quality, with problematic histories predicting negative maternal affect when marriages were less positive/more negative and supportive histories predicting positive maternal affect when marriages were more positive/less negative. Unanticipated results also revealed that reports of supportiveandrejecting parenting in childhood were associated with low-negative maternal affect when marriages were of high quality. These findings were interpreted in terms of buffering and gatekeeping processes, whereby marital quality defines both conditions of continuity and discontinuity with respect to the intergenerational transmission of parenting. Follow-up analyses revealed that physical attractiveness might determine which women with more problematic childrearing histories end up in more positive/less negative marriages that function protectively with respect to the intergenerational transmission of parenting. These results are particularly relevant to the study of developmental psychopathology not only by revealing risk and protective factors, but also by showing that processes at work in high-risk samples also seem to function under lower risk conditions.
