Maternal Worries about Child Underweight Mediate and Moderate the Relationship Between Child Feeding Disorders and Mother–Child Feeding Interactions

OBJECTIVE To examine the role of maternal worries about child underweight and undereating in mother-child feeding interactions with children having a feeding disorder (FD). METHOD Participants were 27 children diagnosed with nonorganic-based FD and 28 children without FD. Mothers were interviewed about their worries about child underweight and undereating. Mother-child interactions were videotaped during feeding. RESULTS Maternal child weight-related worries acted as both a mediator and a moderator. The more negative mother-child interactions found in the FD group, compared to the control group, were explained by greater maternal worry regarding child underweight. Furthermore, mother-child interactions within the FD group were not at risk per se, but only when coupled with high maternal worries about childrens underweight. CONCLUSION Worry about child underweight partially explains the development of negative feeding interactions when having children with FD, signifying clinical implications for the treatment of FD.

Respiratory sinus arrhythmia and heart period in infancy as correlates of later oppositional defiant and callous-unemotional behaviors

Extant literature suggests that oppositional defiant disorder (ODD) and callous-unemotional (CU) behaviors in childhood and adolescence are associated with distinct patterns of psychophysiological functioning, and that individual differences in these patterns have implications for developmental pathways to disorder. Very little is known about the associations between psychophysiological functioning in infancy and later ODD and CU behaviors. This study examined associations between basal autonomic nervous system (ANS) functioning in infancy and ODD and CU behaviors in later childhood. Using longitudinal heart period (HP) and respiratory sinus arrhythmia (RSA) data from the Durham Child Health and Development Study (N = 206), the current study tested associations within a structural equation modeling framework, between continuous measures of HP and RSA across the first 2 years of life, and later ODD and CU behaviors at first grade. Results indicate that ODD and CU behaviors in childhood are associated with lower baseline RSA, but not HP, across infancy. The implications of these findings for developmental models of ODD and CU behaviors are discussed.

Prematurity, ethnicity and personality: risk for postpartum emotional distress among Bedouin-Arab and Jewish women

Background: Mothers of preterm infants are at high risk for postpartum emotional distress. This risk is further increased for women from ethnic minority groups due to specific stressors such as lack of social support, low socioeconomic status and restricted access to health providers and facilities. Objective: This study focused on postpartum emotional distress among Bedouin-Arab mothers, an understudied ethnic minority group living in Israel. Specifically, we examined how premature birth, ethnicity and personality interact in placing Bedouin-Arab and Jewish mothers at risk for postpartum emotional distress. Methods: Participants included 156 mothers of preterm infant (48 Bedouin; 108 Jewish) and 177 mothers of full-term infants (55 Bedouin; 122 Jewish). Measures included maternal reports of emotional distress (i.e. depression symptoms and parental role alteration stress) and the personality trait of self-criticism. Results: Bedouin mothers of preterm infants experienced the highest level of depression symptoms and parental role alteration stress compared to all other mothers. Furthermore, although no group difference was found in self-criticism, Bedouin mothers were more vulnerable to the negative effect of self-criticism than Jewish mothers. Vulnerability to self-criticism varied between the full-term and preterm groups, and in the context of depression or parental role alteration stress. Conclusion: Results are discussed with regard to the unique characteristics of the Bedouin society and the social status of Bedouin women. Clinical implications stressing the need for culturally sensitive adjustments that should be implemented in NICU environment are suggested.

Children’s Executive Function Attenuate the Link Between Maternal Intrusiveness and Internalizing Behaviors at School Entry

The goal of this study was to examine the independent and interactive roles of harsh-intrusive maternal behaviors and children’s executive function in the development of internalizing behaviors across the first years of school. A diverse sample (58% African American, 42% European American) of 137 children (48% female) was followed from kindergarten (age 5 years) through school entry (ages 6–7 years). At age 5, maternal harsh-intrusive parenting behaviors were rated from a mother–child structured play task, and children completed 3 executive function tasks that measured inhibitory control, working memory, and attention set-shifting. Teachers reported on children’s internalizing behaviors at ages 5, 6, and 7. Harsh-intrusive parenting behaviors at age 5 years were positively related to internalizing behaviors in the first years of school, whereas high executive function abilities at age 5 years were related to lower internalizing behaviors in the first years of school. In addition, executive function buffered the association between parenting behaviors and internalizing behaviors such that the link between harsh-intrusive parenting and child internalizing behaviors was evident only among children with low executive function and not among children with high executive function. Interventions that focus on reducing negative parenting behaviors and improving children’s executive function may prevent internalizing behaviors from increasing during times of social and academic challenge.

Assessment of infant sleep: how well do multiple methods compare?

The current study compares sleep variables obtained from videosomnography, actigraphy, and sleep diaries, three of the most common sleep assessment methods used in infant sleep studies. Using a sample of 90 African American 3-month olds, we compare correlations and discrepancies for seven sleep variables across each of the three pairs of assessment methods for one night of a week-long sleep study. These seven variables are indicative of sleep schedule (e.g. sleep onset time, rise time), duration (e.g. sleep period, sleep time, wake time), and fragmentation (e.g. night wakings, longest sleep period). We find that across all sleep assessment methods, correlations are highest for variables indicative of sleep schedule, and lowest for variables indicative of sleep fragmentation. Comparing the magnitude and significance of the discrepancies, we find that actigraphy and sleep diaries significantly overestimate sleep period duration and underestimate the number of night waking episodes, compared with videosomnography. Actigraphy and sleep diaries were more concordant with one another than with videosomnography. Epoch-by-epoch analyses indicated that actigraphy had low sensitivity to detect wakefulness, compared with videosomnography. Contrary to our hypothesis, the discrepancies between sleep assessment methods did not vary widely based on infant sleep location (own room vs. parents room) or sleep surface (own bed vs. parents bed). Limitations and implications of these findings for future research are discussed.

Maternal depressive symptoms, mother-child interactions, and children's executive function

This study examined the independent and mediated associations between maternal depression symptoms (MDS), mother-child interaction, and child executive function (EF) in a prospective longitudinal sample of 1,037 children (50% boys) from predominantly low-income and rural communities. When children were 6, 15 and 24 months of age, mothers reported their level of depressive symptomatology. At 24 and 36 months of age, mother-child interactions during play were rated for warmth-sensitivity and harsh-intrusiveness, and dyadic joint attention and maternal language complexity were assessed from a book sharing activity. Children’s EF (i.e., inhibitory control, working memory, and set shifting) were assessed at ages 36 and 48 months using a battery of six tasks. Results indicated that MDS at ages 15 and 24 months were negatively associated with children’s EF at age 48 months. Additionally, harsh-intrusive mother-child interactions partially mediated this link. Although warmth-sensitivity, dyadic joint attention and maternal language complexity were all longitudinally related to EF, they did not serve as mediating mechanisms between MDS and EF. These results were obtained while controlling for multiple demographic factors, children’s earlier cognitive abilities, maternal general distress and childcare experiences. Findings from this study identify 1 mechanism through which early exposure to MDS could be related to children’s EF.
