Maternal expressions of positive emotion for children predicts children's respiratory sinus arrhythmia surrounding stress.

The aim of this study is to assess whether positive emotional exchanges (i.e., emotion coregulation) within the mother-child dyad play a protective role in children's physiological response to a distressing task. Specifically, we test whether positive emotion coregulation among mothers and their preschool-aged children is associated with children's respiratory sinus arrhythmia (RSA) at baseline, during, and following a frustration task. One hundred Singaporean mother-child dyads (Mchildage  = 3.5 years) participated in a standardized "Laughing Task" in which positive emotional constructs were measured. Children also participated in a frustration task while RSA was continuously monitored. Hierarchical linear regressions revealed that greater maternal positive emotional responses to children were associated with child RSA at baseline and in recovery from frustration, but not during frustration. These findings have implications for the important role that positive emotion responsivity from mothers may play in children's developing autonomic response systems, and underscore the need for longitudinal work on this topic.

Mother-child adrenocortical synchrony: Roles of maternal overcontrol and child developmental phase.

An increasing amount of empirical attention is focused on adrenocortical synchrony as an index of biobehavioral co-regulation between parent and child in the context of early child development. Working with an ethnically diverse community sample of children (N = 99, 50.5% male, ages 9-12), we collected saliva samples from mother-child dyads prior to and after a laboratory-based performance challenge task, and tested whether maternal overcontrol and child age moderated dyadic synchrony in cortisol. Results revealed that cortisol levels between mothers and children were significantly positively correlated at pretask for dyads with mean age and older children only, at 25-min post-task for all dyads, and at 45-min post-task for all dyads. Higher overcontrol/older child dyads exhibited a unique pattern of cortisol synchrony wherein at pretask, mother-child levels had the strongest positive correlation, whereas at 25 and 45 min, mother-child cortisol levels were significantly inversely correlated. These findings contribute to theory and research on parent-child relationships by examining parenting behavior, developmental stage, and adrenocortical synchrony in tandem.

Mother-child dyadic responses to children facing challenges: An examination across ethnicities.

The current study (a) examined ethnic differences in mothers' and children's responses to children's performance in a challenging task, (b) tested the associations among children's desire for assistance, maternal control, and children's emotional responses to the challenge, and (c) explored whether these associations held across three ethnicities-Asian Americans (AA), Latinx Americans (LA), and European Americans (EA). Results showed that children's emotional arousal significantly increased and emotional valence became significantly less positive over the course of children experiencing repeated challenges in front of their mothers. In terms of ethnic differences, LA mothers exhibited more control than EA mothers, but LA children responded less negatively to the challenging task than EA children. AA dyads did not significantly differ from LA or EA dyads on any maternal or child responses. However, regardless of ethnicity, stronger child desire for assistance was associated with greater maternal control and greater maternal control was associated with less emotional arousal and more positive child emotional valence. These findings suggest that, in a challenging context, maternal control is likely experienced by children as guidance that mitigates decreases in positive emotion. Our work has implications for interventions to encourage more emotionally responsive parental involvement with children in late childhood and early adolescence.

Caregiver emotion regulation predicts trajectories of psychopathology during pediatric cancer treatment.

Elevated child and caregiver psychopathology are observed in families of children with cancer, with a subset developing clinically significant symptoms. This study examines whether caregivers' resting respiratory sinus arrhythmia (RSA) and observed emotion regulation (ER) are protective against caregiver and child psychopathology during the first year of pediatric cancer treatment. Primary caregivers of children recently diagnosed with cancer (N = 159; child Mage = 5.6 years; children 48% male, 52% female) completed 12 monthly questionnaires. At Month 3, primary caregivers were interviewed about their experiences of emotions, and their resting RSA was measured. Data were analyzed using multilevel models. Observed ER was associated with lower caregiver anxiety, depression, and posttraumatic stress symptoms (PTSS) 1 year postdiagnosis but was not associated with children's symptoms. Resting RSA had a significant positive association with child depression/anxiety at the start of treatment and Month 12 child PTSS. Findings suggest that caregivers would benefit from interventions to manage their negative emotions at the start of cancer treatment. Additionally, caregivers who are more physiologically regulated may be more attuned to their children's negative emotions. Our findings highlight the importance of taking a multimethod approach to understanding how ER impacts functioning. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Caregiver perceived financial strain during pediatric cancer treatment: Longitudinal predictors and outcomes.

OBJECTIVE: Previous work has examined family income and material hardship in pediatric cancer. However, few studies have focused on perceived financial strain (PFS), or the extent to which caregivers perceive financial stress and worry related to their child's cancer. The current study addresses this gap by a) describing the trajectory of perceived financial strain over the first year of pediatric cancer treatment; b) examining sociodemographic predictors of that trajectory; and c) examining associations between PFS and caregiver and child psychological adjustment. METHOD: Primary caregivers of children (Mage = 6.31) recently diagnosed with cancer provided 12 monthly reports of their own perceived financial strain and depression, anxiety, and posttraumatic stress symptoms, as well as their child's internalizing and externalizing symptoms. Data were analyzed using multilevel models. RESULTS: Caregiver PFS decreased over the first year of treatment. Nonmarried caregivers and those with lower income reported higher levels of PFS over time. Caregivers with higher PFS relative to other caregivers and relative to their own average PFS in a given month experienced psychological maladjustment. PFS was not associated with child adjustment. CONCLUSIONS: On average caregivers perceive less financial strain over the first year of treatment; however, nonmarried caregivers and those with lower income are at risk for higher PFS over time, and PFS may contribute to psychological maladjustment in caregivers. Caregivers may benefit from psychosocial support focused on managing financial strain. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Interaction between the Opioid Receptor OPRM1 Gene and Mother-Child Language Style Matching Prospectively Predicts Children's Separation Anxiety Disorder Symptoms.

Recent research suggests that lower mother-child language style matching (LSM) is associated with greater physiological reactivity and insecure attachment in school-aged children, but to date no studies have explored this measure of parent-child behavioral matching for its association with children's anxiety symptoms, a well-known correlate of attachment insecurity and heightened physiological reactivity. There is also considerable evidence of genetic risk for anxiety, including possession of the OPRM1 minor allele, 118G. In the current study (N = 44), we expand upon what is known about children's genetic and environmental risk for anxiety by examining the unique and interactive effects of mother-child LSM and the OPRM1 polymorphism A118G on school-aged children's separation anxiety disorder (SAD) symptoms. SAD symptoms were measured both concurrently with LSM and OPRM1 genotype and two years later through self-report. No significant associations emerged between LSM or OPRM1 and concurrent Time 1 SAD symptoms. However, lower LSM and 118G minor allele possession were both associated with greater SAD symptoms at Time 2; further, the interaction between LSM and OPRM1 genotype significantly predicted SAD symptoms beyond the main effects of the two variables. Possession of the minor allele was only associated with greater SAD symptoms among children in low LSM dyads, whereas children with the minor allele in high LSM dyads showed non-significantly lower SAD symptoms. These findings and a proportion affected analysis provide support for a differential susceptibility model of gene by environment interactions for the OPRM1 gene. We discuss the implications for predicting children's separation anxiety across development.
