Respiratory Sinus Arrhythmia Acts as a Moderator of the Relationship Between Parental Marital Conflict and Adolescents' Internalizing Problems

Negative family expressiveness and adolescents' externalizing problems: Respiratory sinus arrhythmia as a moderator and anger regulation as a mediator

Family environment, emotion regulation and biological sensitivity have been shown to be associated with adolescents' externalizing problem behaviours. However, findings regarding respiratory sinus arrhythmia (RSA) reactivity are mixed and sometimes contradictory. This study aims to clarify the roles of RSA reactivity and anger regulation in the relationship between negative family expressiveness (NFE) and adolescents' externalizing behaviour by measuring RSA reactivity during the Parent-Adolescent Interaction Task (PAIT), designed to simulate a naturalistic negative family environment. In this study, 125 Chinese adolescents (M = 13.95 years, SD = 0.95; 48% male) completed questionnaires assessing negative family expressiveness, anger regulation and externalizing problems. Additionally, we collected electrocardiogram and respiration data during both the resting period and a 10-min PAIT. Results showed that anger regulation mediated the relationship between NFE and externalizing problem behaviours. Moreover, adolescents' RSA reactivity moderated this mediation effect, even after controlling for baseline RSA. Greater RSA suppression potentially indicated greater susceptibility, with the relationship between NFE and anger regulation being more pronounced in adolescents with greater RSA suppression compared to those with lesser RSA suppression. These findings highlight the importance of considering physiological systems, especially within the context of adverse family environments, when studying the relationships with externalizing problems.

Siblings at home: Moderating influence of sibling presence and composition on the relation between problem behaviors and Theory of Mind in early childhood

Despite the prevalence of internalizing and externalizing difficulties in children, the impact of these problem behaviors on the development of important social cognitive skills, such as Theory of Mind (ToM), is not well-understood. Indeed, many studies that have explored relations between problem behaviors and ToM report inconsistent findings. A possible reason for these disparities may be a lack of accounting for social protective factors within the home, such as the presence and number of siblings. Here, we explored the moderating influence of sibling presence and number on the relation between problem behaviors (i.e., internalizing and externalizing) and ToM. A total of 184 children (88 boys; Mage = 64.6 months, SD = 10.39) completed six well-validated ToM tasks while mothers reported on their children's externalizing and internalizing behaviors. Children who had siblings living in the same home exhibited higher ToM than children without siblings. In addition, both sibling presence and number of siblings moderated the relation between children's externalizing behaviors and ToM, such that in children without siblings externalizing behaviors were negatively associated with ToM. In contrast, children with siblings had similar ToM regardless of externalizing behaviors. As well, children with relatively fewer siblings and higher externalizing behaviors displayed lower ToM than children with relatively more siblings and higher externalizing behaviors. We did not detect a moderating effect of sibling presence or number on the relation between internalizing behaviors and ToM. These findings provide support for siblings' protective utility within the context of children's social cognition.

Physiological and Family-Level Correlates of Autistic Adolescents' Sleep Quality

PURPOSE

Autistic adolescents commonly experience sleep-related difficulties and prior studies have sought to separately examine physiological and family-level predictors of their sleep quality. The current study aimed to conceptually replicate and extend to an adolescent sample a prior study that found respiratory sinus arrhythmia was associated with sleep quality in autistic children. In addition, the current study also examined whether the quality of the family environment was associated with sleep quality in autistic adolescents.

METHODS

The sample consisted of 107 autistic adolescents who completed a baseline measure of respiratory sinus arrhythmia and then watched a video of their parents engaged in a discussion about a topic of disagreement while their respiratory sinus arrhythmia reactivity was measured. Adolescents also completed questionnaires measuring their sleep quality and family environment.

RESULTS

In regression models, adolescents' physiological functioning was not a significant predictor of their sleep quality; however, adolescents living in poorer quality family environments reported worse sleep quality after controlling for their physiological functioning. The interaction between physiological functioning and the family environment predicting sleep quality was non-significant.

CONCLUSION

Although the current study did not conceptually replicate prior work, the findings highlight the importance of the family environment for adolescents' sleep. Implications and future directions are discussed.

Does Parasympathetic Nervous System Activity Exacerbate Depressive Symptoms in College Students Who Experienced Parent-Child Separation? A Longitudinal Examination

Childhood separation caused by parental migration increases the risk of suffering depressive symptoms among college students. However, most studies in this field have focused on environmental factors and largely ignored the role of physiological reactivity to stress (e.g., parasympathetic nervous system activity) in this process. The present study examined the long-term effects of the parent-child separation experience on depressive symptoms in college students, and explored the moderating role of parasympathetic nervous system (PNS) activity in these relationships. The participants were 242 college students (Mage = 18.74 years, SD = 0.79; 32.2% male), including 149 college students who experienced parent-child separation and 93 college students without this experience. Using a three-wave longitudinal design, participants completed the measures of the parent-child separation experience, PNS activity (measured via respiratory sinus arrhythmia, RSA), and depressive symptoms at Time 1 (T1, before the COVID-19 lockdown). Their depressive symptoms were again measured at Time 2 (T2, during the COVID-19 lockdown) and Time 3 (T3, after the COVID-19 lockdown). The results showed that the parent-child separation experience positively predicted depressive symptoms in college students at three time points. Moreover, the parent-child separation experience positively predicted depressive symptoms at T2 among males with less and average RSA suppression but positively predicted depressive symptoms at T2 among females with greater RSA suppression. These findings indicate a long-term effect of parent-child separation on depressive symptoms in college students that still exist after they entered university, and that the effect varies depending on PNS activity and gender.

The association between online learning, perceived parental relationship, anxiety, and depression symptoms among secondary school students: insight from symptom network and cross-lagged panel network approach

INTRODUCTION

Anxiety and depression often co-occur in adolescents, with factors from family and school playing a significant role in the comorbidity. However, network analysis has not examined and clarified the detailed bridge and central symptoms of this comorbidity caused by online learning and perceived parental relationships across different COVID-19 times.

METHODS

Over four months, 2,356 secondary school students completed the Patient Health Questionnaire-9 and Generalized Anxiety Disorder Scale-7. Participants were divided into harmonious and disharmonious groups based on their answers to a question about parental conflicts.

RESULTS

The results indicated that adolescents perceiving more parental conflicts showed a denser comorbidity network after four months of online learning. Significant bridge symptoms decreased from three to two across two waves in the harmonious group, while in the disharmonious group, they increased from two to three. The number of central symptoms increased from one in wave 1 to three in wave 2 for the harmonious group, while four in wave 1 decreased to two in wave 2 for the disharmonious group. Furthermore, the CLPN analysis revealed that the strongest positive cross-lagged edge intensity between symptoms was anhedonia-energy in the harmonious group, with anhedonia being the most trigger symptom. In contrast, for the disharmonious group, guilt-suicide and trouble relaxing-excessive worry were the strongest cross-lagged edge, and trouble relaxing was the most trigger symptom.

CONCLUSION

These findings may have implications for interventions designed to promote adolescent mental health in the context of online learning and parental conflicts.

Communication and sexual skills in marital functioning and satisfaction and reduced marital conflicts among Iranian couples: A systematic review

This study aims to examine the effectiveness of communication and marital (sexual) skills in marital functioning and satisfaction and reduced marital conflicts among Iranian couples. The research literature has been collected from Magiran, SID, Noormags, ISC, and Civilica databases from 2006 to 2021. In the initial search, 104-related articles were extracted and after removing the duplicates, and screening the title and abstract, 34 articles were identified as relevant. After screening the full text of the articles, 20 studies were selected based on the inclusion criteria. According to the studies reviewed, the findings demonstrated that both interventions based on communication skills training and marital (sexual) skills training have improved marital satisfaction, sexual functioning and sexual satisfaction, and reduce marital conflicts. But the reviewed studies also had several blind spots and limitations were discussed in the article.

Social interaction anxiety and sleep quality in youth: Individual difference in childhood adversity and cardiac vagal control

BACKGROUND

Social interaction anxiety and sleep problems are prevalent during adolescence. Social interaction anxiety undermines sleep quality, however, little is known whether the association between social interaction anxiety and sleep quality is moderated by environmental factors such as childhood adversity and individual factors such as cardiac vagal control. This study sought to investigate the moderating effects of childhood adversity and cardiac vagal control on the link between social interaction anxiety and sleep quality.

METHOD

The Social Interaction Anxiety Scale, the Pittsburgh Sleep Quality Index and the Childhood Trauma Questionnaire were administered to 274 adolescents, who received 3-min resting ECG recording to assess respiratory sinus arrhythmia (RSA) as an index of cardiac vagal control.

RESULTS

Social interaction anxiety was negatively associated with sleep quality, and this association was moderated by childhood adversity and cardiac vagal control. In specific, social interaction anxiety was negatively associated with sleep quality among adolescents with low childhood adversity regardless of cardiac vagal control. Sleep quality was generally disrupted when adolescents exposed to high childhood adversity, but the negative association between social interaction anxiety and sleep quality among adolescents with high childhood adversity could be amortized by high cardiac vagal control.

LIMITATIONS

Cross-sectional design precluded establishing causality among variables.

CONCLUSION

These findings suggest that high cardiac vagal control reflecting better self-regulation might buffer the negative effect of social interaction anxiety on sleep quality particularly among adolescents exposed to early life stress.

Childhood trauma, intraindividual reaction time variability, baseline respiratory sinus arrhythmia, and perceived relapse tendency among males with substance use disorders

Background: People with substance use disorders (SUDs) who have experienced serious childhood trauma may have executive function impairments contributing to relapse. Baseline respiratory sinus arrhythmia (RSA) reflects physiological regulation capacity, which has been found to buffer the negative effects of childhood trauma. Baseline RSA has also been found to be related to intraindividual reaction time variability (IIRTV), which is an index of executive function.Objectives: The present study examined the relationship between childhood trauma and perceived relapse tendency, the mediation role of IIRTV, and the moderation role of baseline RSA.Methods: The study is cross-sectional, a total of 110 males with SUDs participated (Mage = 46.45 years, SD = 11.24). The Childhood Trauma Questionnaire and Intention to Rehabilitate Questionnaire were used to assess childhood trauma and perceived relapse tendency, the two-choice oddball task was used to measure IIRTV, and electrocardiogram (ECG) data were collected to obtain baseline RSA.Results: IIRTV mediated the relationship between childhood trauma and perceived relapse tendency (Coeff = 0.049, Boot CI [0.004, 0.121]); interaction of childhood trauma and Baseline RSA negatively influences IIRTV (β = -0.208, t = -2.022, p = .046).Conclusion: The results suggest that males with SUDs who have experienced serious childhood trauma may have executive function impairments that contribute to relapse, and baseline RSA may buffer the negative effect of childhood trauma on IIRTV. These findings suggest that the prevention of relapse through cognitive enhancement can be complemented by the enhancement of physiological regulation.

The Protective Role of the Autonomic Nervous System in Intergenerational Cycles of Neglect

Offspring of parents who experienced childhood neglect are at increased risk for developing internalizing problems. Empirical evidence suggests this link is principally mediated through parenting behavior. However, such intergenerational cycles of adversity are found to be disrupted in many families. Parasympathetic nervous system functioning is well documented to mediate individuals' emotion regulation biologically. Respiratory sinus arrhythmia (RSA) is a validated biomarker for parasympathetic activity. The goal of the current study was to investigate the moderating role of parent RSA reactivity in the effect of parents' childhood neglect on their children's internalizing problems, through parental acceptance. Physiological and survey data were collected from 145 dyads (94% mothers; Youth Mage = 12.9, Youth SDage = 0.85). Results suggest that the effect of parents' childhood neglect on their child's internalizing problems was conditional on parents' RSA reactivity. Specifically, higher levels of parents' neglect were only linked to increased risk for youth internalizing problems if parents exhibited a lack of RSA withdrawal. Further, this moderating effect was found to be mediated through parental acceptance. Findings suggest understanding intergenerational consequences of child maltreatment contexts should include consideration of bioregulatory factors.

Respiratory sinus arrhythmia, negative social interactions, and fluctuations in unmet interpersonal needs: A daily diary study

INTRODUCTION

This study examined daily fluctuations in the unmet interpersonal needs of thwarted belongingness and perceived burdensomeness in response to daily negative social interactions, as well as the moderating role of respiratory sinus arrhythmia (RSA) across adolescents at lower and higher risk for suicidal ideation.

METHODS

Fifty five adolescents with major depressive disorder (MDD, i.e., higher-risk group) and without MDD (i.e., lower-risk group) completed measures of resting RSA, and daily measures of negative social interactions, perceived burdensomeness, and loneliness, as a proxy for thwarted belongingness, for 10 consecutive days. Within-person analyses examined the association between daily negative social interactions and unmet interpersonal needs, and the moderating roles of RSA and higher-risk group status. Between-person analyses also examined the association between RSA and unmet interpersonal needs across groups.

RESULTS

At the within-person level, participants reported more unmet interpersonal needs on days when they reported more negative social interactions. At the between-person level, higher RSA was associated with decreased loneliness in both groups, and decreased burdensomeness among the higher-risk group.

CONCLUSIONS

Negative social interactions are associated with daily unmet interpersonal needs. Higher RSA may serve as a protective factor mitigating risk for unmet interpersonal needs, particularly burdensomeness, among adolescents at higher risk for suicidal ideation.

Adverse childhood experiences and Chinese young adults' sleep quality: Moderation of resting respiratory sinus arrhythmia

This study examined the moderating roles of resting respiratory sinus arrhythmia (RSA) in the relations between adverse childhood experiences (ACEs) and sleep quality (i.e., sleep efficiency, perceived sleep quality, and daily disturbances) in young adulthood. Chinese young adults (N = 259; M_age = 25.85 years) reported on their adverse childhood experiences retrospectively and current sleep quality. Their electrocardiogram (ECG) and respiration data were recorded while they were seated resting and resting RSA scores were computed. Results indicated that ACEs were associated with poor perceived sleep quality and greater daily disturbances among young adults who showed low resting RSA. The associations were not significant among those who showed high resting RSA. These findings suggest that high resting RSA may serve as a protective factor for young adults' sleep against adverse childhood experiences and these effects were consistent for different biological sex and sexual orientation groups.

The longitudinal links between marital conflict and Chinese children's internalizing problems in mainland China: Mediating role of maternal parenting styles

The present study explored the role of parenting styles as mediating mechanisms in the link between marital conflict and Chinese children's internalizing problems. Participants were N = 1269 families (mothers, fathers, and children) from Shanghai, P. R. China. Multisource assessments were employed at three time points. Mothers and fathers reported their marital conflict and parenting styles (authoritative, authoritarian) and teachers and children reported on children's internalizing problems. Results from the Actor-Partner Interdependence Model (APIM) showed significant actor and partner effects for associations between marital conflict and parenting styles. After controlling for internalizing problems at Time 1, only maternal authoritarian parenting continued to mediate the relations between mothers' reported marital conflict and change in children's internalizing problems over time. This research provides valuable information about how important aspects of parenting influence the relations between marital conflict and internalizing problems among Chinese children.

Temperamental and physiological regulatory capacity in infancy: Links with toddler behavior problems

Although correlates of temperamental regulatory processes in childhood have been well established, there is considerably less work examining correlates and moderators of rudimentary forms of temperamental regulation in infancy. We examined whether infants' physiological regulation indexed via changes in respiratory sinus arrhythmia (RSA) across phases of the Still-Face Paradigm moderated the association between maternal-reported infant regulatory capacity at 8 months (N = 50, M_age = 8.51 months, SD_age = 0.28 months, 25 girls) and behavior problems at 14 months. We found that cardiac vagal regulation from baseline to still-face moderated the relation between infant regulatory capacity at 8 months and behavior problems at 14 months. Among infants who displayed relatively high cardiac vagal regulation from baseline to still-face, regulatory capacity was negatively associated with behavior problems. There was no relation between regulatory capacity and behavior problems among infants who displayed average or relatively low cardiac vagal regulation. We speculate that high levels of regulatory capacity and cardiac vagal regulation may allow infants to focus their attention outward and cope with emotionally evocative environmental demands as they arise even in the absence of external regulation provided by their caregivers.

Relationship Between Parental Marital Conflict and Social Anxiety Symptoms of Chinese College Students: Mediation Effect of Attachment

Social anxiety has been a common problem among college students and has an adverse impact on their adaptation outcomes. Among influential factors, parental marital conflict and attachment (parental and peer attachment) have been found to be related to social anxiety symptoms of college students; however, little is known how parental marital conflict and attachment jointly contribute to social anxiety symptoms of college students. The current study explored this issue. Self-reported questionnaires of perception of children of interparental conflict scale, inventory of parent and peer attachment, and the social interaction anxiety scale were administered to 707 undergraduate students (Mean age = 19.27, SD = 0.97). Results indicated that perceived parental marital conflict was positively correlated with social anxiety symptoms and was negatively associated with parental and peer attachment. Parental and peer attachments were negatively correlated with social anxiety symptoms. Mediation analyses indicated that perceived parental marital conflict exerted its indirect effect on social anxiety symptoms through a serial multiple mediation role of parental and peer attachment. The present findings highlight the serial multiple mediation role of parental and peer attachment in the relationship between perceived parental marital conflict and social anxiety symptoms of college students.

Childhood abuse and social anxiety symptoms among young adults: Moderating role of respiratory sinus arrhythmia suppression to social stress

BACKGROUND

Childhood abuse (CA) has been considered as an environmental risk factor for the development of social anxiety symptoms. Respiratory sinus arrhythmia (RSA) is a biomarker that has been found to interact with environmental stressors to affect psychopathological symptoms. However, little is known whether RSA moderates the relationship between CA and social anxiety symptoms.

OBJECTIVE

The current study aimed to examine the relationships between CA and two forms of social anxiety symptoms including social performance anxiety symptoms (SPAS) and social interaction anxiety symptoms (SIAS), and the moderating role of baseline RSA and/or RSA suppression to a social-evaluative stress in these links.

PARTICIPANTS AND SETTING

A total of 157 Chinese undergraduate students (Mage = 18.96, SD = 0.85, 85 % females) participated in this study.

METHOD

Participants completed the short form of Childhood Trauma Questionnaire, Social Phobia Scale and Social Interaction Anxiety Scale to assess CA, SPAS and SIAS, and then underwent a social stress protocol (a public speech task) during which their baseline RSA and stress induced RSA were obtained.

RESULTS

CA was positively correlated with SPAS but was not correlated with SIAS. RSA suppression to social stress moderated the associations between CA and two forms of social anxiety symptoms, such that CA was positively associated with SPAS and SIAS among individuals with blunted RSA suppression, but not among those with greater RSA suppression.

CONCLUSIONS

Greater social stress RSA suppression as a better physiological regulation marker might ameliorate the negative effect of CA on social anxiety symptoms.

Associations between autonomic nervous system activity and risk-taking and internalizing behavior in young adolescents

Dysregulated autonomic nervous system (ANS) activity has been associated with adolescent risk‐taking and internalizing behavior, but previous results in community samples have been mixed. We investigated whether ANS activity was associated with higher risk‐taking and internalizing behavior in young adolescents (age 11/12; n = 875), and whether adolescents' gender, parents' parenting style or a combination of both moderated these associations. Adolescents and their parents were recruited as part of the population‐based, longitudinal Amsterdam Born Children and their Development (ABCD) study. Risk‐taking behavior was assessed with the Balloon Analogue Risk Task and the personality characteristics sensation seeking and impulsivity, measured with the Substance Use Risk Profile Scale (SURPS). Internalizing behavior was assessed via the SURPS subscales anxiety sensitivity and hopelessness. Authoritative (AUTH‐SW) and authoritarian (AUTH‐S) parenting styles were measured with the Parenting Styles and Dimensions Questionnaire. Resting ANS activity was assessed via heart rate and respiratory sinus arrhythmia (RSA). Hierarchical, multivariable regression analyses showed higher RSA, but not heart rate, being associated with higher risk‐taking behavior and sensation seeking. The associations between ANS activity and risk‐taking variables were not significantly moderated by gender, parenting, or interactions between gender and parenting. Our findings suggest that RSA activity may be a relevant factor in mild to moderate risk‐taking behavior in adolescents from the general population, regardless of their gender or the type of parenting they experience.

Dysregulated autonomic nervous system activity has been associated with adolescent risk‐taking and internalizing behavior, but previous results in community samples have been mixed. Our findings suggest that in adolescents from the general population, respiratory sinus arrhythmia activity may be a relevant factor in mild to moderate risk‐taking behavior but not in internalizing behavior, regardless of adolescents' gender or the type of parenting they experience.

Getting to the heart of childhood empathy: Relations with shyness and respiratory sinus arrhythmia

Although prior studies have found that shyness and empathy are inversely related and that well-regulated children tend to express empathic behaviors more often, little work has assessed combinations of these factors in predicting affective and cognitive empathy in early childhood. The authors examined relations among shyness, resting respiratory sinus arrhythmia (RSA), and observed affective and cognitive empathy in a sample of 130 typically developing children (M_age  = 63.5 months, SD = 12.2; 62 males). Shyness was assessed by observing children's behaviors during a self-presentation task, and this observed measure was then combined with a maternal report of children's temperamental shyness. Children's shyness predicted lower levels of both affective and cognitive responses to an experimenter feigning an injury. Resting RSA moderated the relation between children's shyness and observed empathy such that relatively higher shyness combined with lower RSA levels conferred the lowest levels of cognitive empathy. Children who were relatively low in shyness exhibited similar levels of cognitive empathy across different levels of RSA. However, this moderation was not found when predicting children's affective empathy. Our results suggest that not all shy children are alike in terms of their empathic behaviors: shy children who are physiologically dysregulated appear to have difficulties exploring and/or processing others' pain.

Attachment security in infancy predicts reduced parasympathetic reactivity in middle childhood

Children with histories of secure attachments during infancy are expected to develop healthier patterns of physiological activity at rest and in response to a stressor than children with insecure attachments. The present study examined longitudinal associations between infant attachment security and children's respiratory sinus arrhythmia (RSA) at rest and in response to a frustration task at age 9. The study focused on a sample of children referred from Child Protective Services (N = 97). RSA reflects the regulation of the parasympathetic branch of the autonomic nervous system, is sensitive to environmental influences, and is associated with emotion regulation. Children with histories of secure attachments during infancy exhibited less RSA withdrawal during a frustration task than children with histories of insecure attachments. Attachment security was not significantly associated with baseline RSA. Results suggest that mitigating parasympathetic reactivity during frustrating situations may be one avenue by which infant attachment security promotes emotion regulation.

Trait impulsiveness and response inhibition in young adults: Moderating role of resting respiratory sinus arrhythmia

Trait impulsiveness is a multifaceted construct that includes motor-, attention/cognitive- and non-planning facets, but how specific impulsiveness facets are associated with the deficit of response inhibition is not well understood. Resting respiratory sinus arrhythmia (RSA), which is considered as an index of cardiac vagal tone has been demonstrated to play a moderating role in the associations between many individual's variables. Whether resting RSA moderates the relationships between the facets of trait impulsiveness and response inhibition remains unknown. To examine these issues, data of self-reported trait impulsiveness, as assessed using the Barratt Impulsiveness Scale (BIS-II), 5-min resting RSA, and response accuracy (ACC) on a modified Go/NoGo task were collected from 132 college students. Results indicated that ACC of NoGo condition on the Go/NoGo task was negatively correlated with BIS motor and BIS total. Trait motor impulsiveness negatively predicted ACC of NoGo condition on the Go/NoGo task in the low resting RSA group but not in the high resting RSA group. This finding suggests that cardiac vagal tone could moderate the association between trait impulsiveness, especially motor impulsiveness, and deficits of response inhibition.
