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

Childhood psychological maltreatment and social anxiety in college students: The roles of parasympathetic nervous system activity and parent-child separation experience

BACKGROUND

Childhood psychological maltreatment is a risk factor for social anxiety in adulthood. Parent-child separation, as one of the most serious adversities in early life, may exacerbate the risk of psychological maltreatment and influence the interactions between childhood psychological maltreatment and biological sensitivity to stress in relation to social anxiety. However, there has been a dearth of work on this issue.

OBJECTIVE

This study investigated the interactive effects between childhood psychological maltreatment and parasympathetic nervous system (PNS) activity on social anxiety in college students by comparing those who experienced parent-child separation versus those who did not. Potential sex differences in the aforementioned associations were tested as an exploratory aim.

PARTICIPANTS AND SETTING

Data were obtained from 264 college students (Mage = 18.45 years, SD = 0.69), including 156 students who experienced parent-child separation and 108 students without this experience.

METHODS

Participants completed measures of childhood psychological maltreatment and social anxiety and reported their parent-child separation experience. The data of PNS activity, measured by respiratory sinus arrhythmia (RSA) reactivity, were obtained during the Trier Social Stress Test (TSST) in the lab.

RESULTS

Childhood psychological maltreatment was positively associated with college students' social anxiety. RSA reactivity moderated the relationship between childhood psychological maltreatment and college students' social anxiety, and the moderating role of RSA reactivity varied with parent-child separation experience and sex.

CONCLUSIONS

Parent-child separation experience influenced the biosocial interactions between childhood psychological maltreatment and PNS activity in relation to individuals' social anxiety, and this effect persisted in adulthood.

Nonlinear Moderation Effect of Vagal Regulation on the Link between Childhood Trauma and Adolescent Internalizing and Externalizing Symptoms

Childhood trauma is a leading early adverse environment that increases psychopathological symptoms. Respiratory sinus arrhythmia (RSA) suppression to challenges as a marker of self-regulation is found to linearly moderate the link between early adverse experiences and psychopathological symptoms, but yielding mixed findings. The present study examined the relationships between childhood trauma and internalizing and externalizing symptoms via a 1.5-year longitudinal design and the quadratic moderation effect of RSA suppression on these relationships among adolescents. In November 2021 (T1), the final sample of 275 Chinese adolescents (Mage = 12.94, SDage = 0.79; 49.82% females) completed the short form of Childhood Trauma Questionnaire and the Achenbach Youth Self-Report-2001 and underwent a speech task during which their baseline RSA and stress exposure RSA were obtained. In June 2023 (T2), 251 adolescents completed the Achenbach Youth Self-Report-2001. Results showed that childhood trauma at T1 was positively correlated with internalizing and externalizing symptoms at T1 and T2. RSA suppression to stress quadratically moderated these associations, such that adolescents with moderate rather than higher or lower RSA suppression had the least internalizing and externalizing symptoms at T1 and T2 when exposed to childhood trauma. The findings suggest that moderate RSA suppression to stress as a marker of optimal vagal regulation buffers the risk of developmental psychopathology from early adverse experiences.

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 relationship between child maltreatment and social anxiety: A meta-analysis

BACKGROUND

Globally, child maltreatment has become a serious problem, affecting individuals' physical and mental health. This meta-analysis aimed to explore the association between child maltreatment and social anxiety.

METHODS

MEDLINE, PsycINFO, EMBASE, Scopus, and Web of Science were searched for articles published by October 2021. Newcastle-Ottawa Quality Assessment Scale (NOS) was used to evaluate the quality of studies. Maltreatment type, sample setting, age, country and measurement instruments were analyzed as moderators.

RESULTS

Twenty-nine studies met the inclusion criteria. Child maltreatment was positively correlated with social anxiety (r = 0.201, 95 % CI [0.171, 0.230]). The moderating effect of maltreatment subtypes was significant whether divided into three types (Q_b = 12.152, p = .002), or five types (Q_b = 11.574, p = .021). Specifically, emotional maltreatment (r = 0.251, 95 % CI [0.201, 0.298]) had a stronger relationship with social anxiety than physical (r = 0.138, 95 % CI [0.085, 0.191]; Q_b = 9.312, p = .002) and sexual maltreatment (r = 0.153, 95 % CI [0.108, 0.197]; Q_b = 9.197, p = .002). However, there was no significant difference in the effect size between physical and sexual maltreatment (Q_b = 0.096, p = .757). Other variables (age, sample setting and country) were not significant moderators.

LIMITATIONS

Only twenty-nine studies were included, and there was high heterogeneity among the studies, the interpretation of the results should be cautious.

CONCLUSIONS

This meta-analysis confirmed the relationship between child maltreatment and social anxiety, especially highlight the harmfulness of emotional maltreatment.

Attachment avoidance and internalizing symptoms: Does respiratory sinus arrhythmia withdrawal make a difference?

OBJECTIVE

This study investigated the association between attachment avoidance and internalizing symptoms and the moderating role of parasympathetic nervous activity (indexed by respiratory sinus arrhythmia withdrawal) in the association.

METHODS

A sample of 109 (M_age = 18.94 years old, SD = 0.92; 69 male) Chinese college students participated in this study. Participants reported attachment avoidance and internalizing symptoms, and their physiological data were collected.

RESULTS

Results showed a positive link between attachment avoidance and internalizing symptoms. Further, respiratory sinus arrhythmia (RSA) withdrawal and attachment avoidance interactively predicted internalizing symptoms. Specifically, the positive relation between attachment avoidance and internalizing symptoms was only found among people of low, but not high, levels of RSA withdrawal.

CONCLUSION

Our study highlighted the importance of considering psychophysiological interactions in predicting internalizing symptoms in college students, and contributed to our understanding of the complicated factors underlying college students' internalizing problems.
