RESUMO
BACKGROUND: Covid-19 pandemic has been profoundly affecting people around the world. While contact restrictions, school closures and economic shutdown were effective to reduce infection rates, these measures go along with high stress for many individuals. Persons who have experienced adverse childhood experiences (ACEs) have an increased risk for mental health problems already under normal conditions. As ACEs can be associated with a higher vulnerability to stress we aimed to assess the role of ACEs on depressive symptoms during the Covid-19 pandemic. METHODS: In a cross-sectional online survey, 1399 participants above the age of 18 years were included during the first lockdown in Germany. Via two-way repeated measures ANOVA, differences in depressive symptoms before (retrospectively assessed) and during the pandemic were analyzed. Linear regression analyses were performed in order to identify predictors for increase of depressive symptoms. RESULTS: Compared to prior to the Covid-19 pandemic, depressive symptoms increased among all participants. Participants with ACEs and income loss reported about a stronger increase of depressive symptoms. Other predictors for increased depressive symptoms were young age and a lack of social support. CONCLUSIONS: Based on these results, ACEs are a significant predictor for an increase in depressive symptoms during the pandemic, indicating that personss with ACEs may be a risk group for mental health problems during the current and potential later pandemics. These findings underline the relevance of support for persons who have experienced ACEs and may help to provide more targeted support in possible scenarios due to the current or possible other pandemics. Besides, economic stability seems to be of prior importance for mental health.

BACKGROUND: Childhood emotional maltreatment can be associated with long-term consequences on mental health. In addition, transgenerational transmission of adverse childhood experiences to the next generation can occur and thus have an impact on the mental health of one's own children. OBJECTIVE: The purpose of this study was to examine the role of stress on the association between childhood emotional maltreatment and parental load what is referred to in this study as limitations in parental functioning that affect the resources available to parents to cope with the demands of raising, caring for, and providing for their child. Furthermore the effect of parental load on the mental health of one's own children will be examined. PARTICIPANTS AND SETTING: N = 237 mother-child dyads (age mother M = 33.76, SD = 4.07 years; age child M = 11.91 months, SD = 0.89 months) from a longitudinal cohort study were examined at two different measuring points. METHODS: Emotional abuse, perceived stress, parental load and child mental health were assessed using self and external report questionnaires. RESULTS: The calculation of a mediation showed that the association of emotional abuse and parental load was completely mediated by perceived stress (indirect effect ab = 0.44, 95 %-CI[0.17, 0.78]). In addition, effects of parental load on the child's mental health (ß = 0.13, 95%CI [0.07;0.20]), mainly hyperactivity (ß = 0.06, 95%CI [0.03;0.11]) and prosocial behavior (ß = -0.04, 95%CI [-0.07; -0.01]), were evident. CONCLUSIONS: The results of this study provide evidence that the mental health of children can be influenced in the long term by increased parental load.

Maternal childhood maltreatment (CM) represents an important factor in the transmission of trauma that may lead to impaired child mental health. Apart from childhood maltreatment insecure attachment has been identified as a risk factor for insensitive caregiving behavior, which may affect child's mental health. The aim of this study is to identify the working mechanisms in the relationship between maternal CM and child mental health, considering maternal attachment representation, mother-child-interaction und maternal helplessness and fear. N = 103 mother-child-dyads from a longitudinal cohort study were examined at four different measuring points. Data was assessed using self and external report questionnaires as well as the AMBIANCE scales during the Strange Situation Procedure and the Adult Attachment Projective Picture System (AAP). Maternal CM experience did not predict an insecure attachment representation (OR = 2.46 [0.98, 6.53], p = .060). Maternal insecure attachment was associated with higher AMBIANCE scores (F(8, 94) = 11.46, p < .001), which indicates more disrupted communication between mother and child. AMBIANCE scores in turn predicted higher self-perceived helplessness (F(9, 93) = 8.62, p < .001) and fear (F(9, 93) = 7.40, p < .001) in mothers. Helplessness and fear both were associated with higher SDQ-scores, indicating more mental health problems in children (F(10, 92) = 3.98, p < .001; F(10, 92) = 3.87, p < .001). The results of this study highlight how even insecure attachment in a low-risk sample has a long-term impact on parenting behavior and child mental health, therefore underlining the need of early intervention programs in affected and at-risk families.

Background: Restrictions imposed by national governments during SARS-CoV-2-pandemic have impacted the mental health of children around the world. Studies have already proven the importance of secure attachment acting as a protective factor in child development. Therefore, children with secure attachment have a higher chance of developing and using appropriate coping mechanisms. Objective: The goal of this study was to explore the possible connection between the pandemic, as well as child attachment, and young children's emotional health. The general hypothesis assumes a lower rate of emotional problems among children with secure attachment and a higher rate of emotional problems among children with insecure-disorganized attachment, as well as an increase of these problems during the pandemic. Method: The analysis included N = 129 mothers (M = 39.98 years) and their children (M = 5.19 years). Via an online survey, which was held at different time points during the pandemic, information on the children's emotional problems was retrieved. The survey used the Strengths and Difficulties Questionnaire (SDQ). Data regarding the quality of attachment was collected via the Strange Situations Test (SST). At this point the participating children were approximately 12 months old. Results: The calculation of a mixed ANCOVA showed, that attachment quality had a significant influence on children's emotional problems [F(2, 121) = 4.01, p = .021]. The interaction effect between time and child attachment reached significance [F(3.45, 208.42) = 3.58, p = .011]. The calculation of an additional mixed ANCOVA showed, that the reported emotional problems of girls were higher than those of boys F(1, 118) = 4.56, p = .035). Conclusions: Our study shows that there is an association between attachment security and emotional problems and the impact of the SARS-CoV-2 pandemic on the mental health of preschool children in Germany. The emotional problems of all children increased, especially the disorganized attached children had been reported as emotionally stressed in the first lockdown. The results indicate the need for preventive services (for children and parents) to promote and maintain stress coping skills in order to maintain children's mental health in times of crisis.
RESUMO
Background: SARS-CoV-2 pandemic have posed great challenges for all families and children. Health risks and fears associated with SARS-CoV-2 negatively affect the parental mental health and perceived stress, which in turn influence parental coping and thereby impairs the mental health and well-being of their children. Additional risk factors within the parents, such as maternal childhood maltreatment (CM) experiences, may increase the risk of children to develop emotional problems during the pandemic. Objective: The purpose of this longitudinal study is to determine whether preschool children of mothers with CM are at higher risk of developing emotional problems during the pandemic than preschool children of mothers without CM. Method: 74 mothers from a birth cohort examining pathways to resilience or vulnerability in the transgenerational transmission of CM, provided information on emotional problems of their children (aged 3-7 years) at two measurement time points (t1: May 2020, t2: March 2021) as part of an online "SARS-CoV-2 pandemic" survey. In addition, parents were asked for a retrospective assessment of their children's emotional problems before the pandemic at time t1. Children's emotional problems were assessed using the "emotional problems" scale of the German version of the Strengths and Difficulties Questionnaire (SDQ) and linked to previously collected data on mothers' childhood maltreatment experiences, which were collected using the German short version of the Trauma in Childhood Questionnaire (CTQ). Results: Our analyses showed that children's emotional problems increased significantly over the SARS-CoV-2 pandemic [F(1.86, 116.88) = 3.72, p = 0.030 η 2 = 0.06] and were rated significantly higher in the group of children of mothers with CM, than in the group of mothers without CM [F(1, 63) = 126.06, p < 0.001 η 2 = 0.67]. Furthermore children's emotional problems of mothers with CM increased significantly more and reached a clinically significant value during the pandemic than for children of mothers without CM [F(1.86, 116.88) = 8.89, p < 0.001, η 2 = 0.12]. Conclusions: Children of mothers with CM appear to be at increased risk of developing emotional problems during the pandemic. CM therefore needs to be considered as an additional risk factor in the impact of the pandemic on children.
RESUMO
BACKGROUND: Social distancing strategies during the SARS-CoV-2 pandemic have left families facing a variety of different constraints. Especially in this stressful time, children need a stable parental home to prevent developmental consequences. Additional risk factors such as maternal childhood maltreatment (CM) may affect mother's psychosomatic health and children's physical well-being in this period. OBJECTIVE: It was aimed to analyze the associations between maternal CM, mother's mental health, and children's physical complaints during the SARS-CoV-2-pandemic. METHOD: Mothers of a well-documented birth cohort from a longitudinal study were included in this study. Psychosomatic health was assessed with the PHQ-D and children's physical health with the GBB-KJ during the pandemic. N = 159 mothers completed the online survey. To describe the maternal CM, data from a longitudinal survey were used. RESULTS: The calculation of three mediation analyses demonstrate that maternal depression symptoms (c-path: ß = 0.10, p = .02; c'-path: ß = 0.07, p = .13), somatic symptoms (c-path: ß = 0.10, p = .02; c'-path: ß = 0.07, p = .13) and psychosomatic symptoms (c-path: ß = 0.10, p = .02; c'-path: ß = 0.06, p = .19) fully mediate the relationship between CM and children's physical health complaints. CONCLUSIONS: Maternal CM experiences seem to be one relevant risk factor during the pandemic and seem to influence the way in which parents deal with stressful situations and increase the risk for depressive symptoms. The present results highlight the importance to provide individually adjusted assistance to help the families to get through the pandemic.

The oxytocin receptor gene (OXTR) is of interest when investigating the effects of early adversity on DNA methylation. However, there is heterogeneity regarding the selection of the most promising CpG sites to target for analyses. The goal of this study was to determine functionally relevant clusters of CpG sites within the OXTR CpG island in 113 mother-infant dyads, with 58 of the mothers reporting childhood maltreatment (CM). OXTR DNA methylation was analyzed in peripheral/umbilical blood mononuclear cells. Different complexity reduction approaches were used to reduce the 188 CpG sites into clusters of co-methylated sites. Furthermore, associations between OXTR DNA methylation (cluster- and site-specific level) and OXTR gene expression and CM were investigated in mothers. Results showed that, first, CpG sections differed strongly regarding their statistical utility for research of individual differences in DNA methylation. Second, cluster analyses and Partial Least Squares (PLS) suggested two clusters consisting of intron1/exon2 and the protein-coding region of exon3, respectively, as most strongly associated with outcome measures. Third, cross-validated PLS regression explained 7% of variance in CM, with low cross-validated variance explained for the prediction of gene expression. Fourth, substantial mother-child correspondence was observed in correlation patterns within the identified clusters, but only modest correspondence outside these clusters. This study makes an important contribution to the mapping of the DNA methylation landscape of the OXTR CpG island by highlighting clusters of CpG sites that show desirable statistical properties and predictive value. We provide a Companion Web Application to facilitate the choice of CpG sites.

The social distancing measures and the related closure of education institutions have confronted young families, in particular, with various challenges. Additional risk factors such as an insecure or even unresolved maternal attachment representation may affect mental health of mothers and their children in times of increased stress such as during the ongoing pandemic. We aimed to analyze the interplay between maternal attachment representation and mother's and children's mental health before and during the SARS-CoV-2-pandemic. 91 mothers completed a "SARS-CoV-2 pandemic survey" examining the pandemic-related stress of their families including their own depressive symptomology and their children's mental health. Our mediation analysis demonstrates that the mothers' depressive symptomology significantly and fully mediated the relationship between maternal attachment representations and children's mental health during the pandemic. In contrast, the indirect effect of the maternal attachment representation on children's mental health before the pandemic through the depressive symptoms experienced by the mothers before the pandemic did not reach significance alongside the total and direct effect. The quality of the maternal attachment representation, promoted by childhood maltreatment, seems to be one relevant risk factor for the mothers' and children's mental health during a stressful time like a pandemic. The risk for mothers to develop depressive symptoms in times of a pandemic is significantly influenced by their current representation of previous attachment experiences. In addition, the mental well-being of mothers showed a considerable influence on the children's mental health during a pandemic. The results underline the necessity to consider unique needs of family members and to offer specific support in the current crisis focusing on attachment issues.
RESUMO
For more than two years, young families have been confronted with a large number of restrictions and following burdens as a result of the SARS-CoV-2 pandemic. In fact, it became evident, that the current circumstances are particularly stressful for child's mental health. With regard to the child's mental health in times of a pandemic, additional factors within the family, such as maternal attachment representations as well as coping strategies and parental behavior, may play an important role. This study aims to investigate the interplay of maternal attachment representation, coping strategies, parental behavior and child's mental health during the SARS-CoV-2 pandemic. In this longitudinal study, previously collected data regarding maternal attachment representation and newly attained data from the SARS-CoV-2-pandemic-assesment (lack of coping strategies, children's mental health and parental behavior) were combined and analyzed. The data were collected in an online survey since beginning of the pandemic, including N = 73 mothers. A path model was calculated in form of multiple linear regression. A path model could be confirmed, which indicates that insecure maternal attachment representation predicts lack of coping strategies during the pandemic [b = 5.55, 95%-CI = (4.51; 6.55), p = 0.001]. Furthermore, lack of coping strategies predicts harmful parental behavior during the pandemic [b = -0.77, 95%-CI = (-1.27; -0.21), p = 0.007], which in turn predicts children's mental health problems, namely behavioral problems [b = -0.08, 95%-CI = (-0.14; -0.01), p = 0.027]. Presence of short-time work and decrease in income since beginning of the pandemic were used as control variables. This means that since the pandemic mothers with insecure attachment representation have an increased risk of having only a few coping mechanisms available, leading to harmful parental behaviors and ultimately affecting the mental health of their children. In conclusion, the pandemic could potentially have a particularly negative influence on mothers with an insecure attachment type and therefore on their children. Therefore, tailored interventions for families should be offered that both focus on the different types of mental health problems in children and support parents in their coping skills.
RESUMO
Introduction: As an especially burdensome experience, childhood maltreatment (CM) can have lifelong consequences on the mental health and wellbeing of an individual well into adulthood. We have previously reported that CM constitutes a central risk factor not only for the development of mental problems, but also for facing additional psychosocial risks, endangering healthy development of mother and offspring throughout life (e.g., financial problems, intimate partner violence, substance use). This study was designed to replicate these findings in a larger, independent study cohort. Method: In this cross-sectional replication study an independent cohort of 533 healthy postpartum women was interviewed within seven days after parturition. CM experiences were assessed retrospectively using the German version of the Childhood Trauma Questionnaire (CTQ) and current psychosocial risk factors for child welfare were assessed using the Konstanzer Index (KINDEX). Results: Of all women, 16.1% experienced emotional and 10.1% physical abuse, 28.5% emotional neglect, 9.4% physical neglect and 10.3% experienced sexual abuse. Most importantly, the higher the CM load the more psychosocial stressors existed in women's life. In Particular, women with higher CM load had a higher risk for mental health problems, intimate partner violence, financial problems, and a higher postnatal stress load. Conclusions: In an independent sample, this study replicated the previous findings that CM and psychosocial risk factors for child welfare were strongly associated in a dose-response manner. Our results emphasize the higher vulnerability of women with a CM history in the postpartum period. To avoid negative consequences for mother and child, a regular and evidence-based screening for CM and psychosocial risk factors during pregnancy and puerperium is needed to identify at-risk mothers early during pregnancy and to provide appropriate support. Hence, our findings highlight the mandatory requirement for an interdisciplinary collaboration of gynecological practices, hospitals and midwifes, along with psychologists and psychotherapists and child and youth welfare services.
RESUMO
Background: Behavioral and physiological (self-)regulation in early life is crucial for the understanding of childhood development and adjustment. The autonomic nervous system (ANS) is a main player in the regulative system and should therefore be modulated by the quality of interactive behavior of the caregiver. We experimentally investigated the ANS response of 18-36-month-old children in response to the quality of maternal behavior during a mother-child-interacting paradigm. Method: Eighty mothers and their children came to our laboratory and took part in an experimental paradigm, consisting of three episodes: a resting phase (E1), a structured play phase (E2), and a free play situation (E3) between mothers and their child. Children's and mother's heart rate (HR), the sympathetic nervous system (SNS) activity via the pre-ejection period (PEP) and the left ventricular ejection time (LVET), and the parasympathetic nervous system (PNS) activity via the respiratory sinus arrhythmia (RSA) were continuously measured by an electrocardiogram. Maternal sensitivity of interactive behavior was assessed by using the Emotional Availability (EA) Scales. Results: Children of mothers with insensitive behavior had a significantly lower RSA at baseline, showed a lack of RSA withdrawal during structured and free play, and had shorter LVET across all episodes compared to children of sensitive mothers. Conclusion: Our findings depict the influence of low-quality maternal interaction on the child's ANS regulation, in calm and more stressful play situations. The overall higher SNS mode with impaired PNS reactivity may negatively influence child's ANS homoeostasis, which may result in a long-term impact on mental and physical wellbeing. Further, the maternal sensitivity may function as a buffer for the stress response of their child. These results could serve as a basis for the development of appropriate psychoeducational programs for mothers of low sensitivity in their interaction with the child.
RESUMO
The quality of maternal caregiving is an important factor in the healthy development of a child. One consequence of prolonged insensitive and atypical maternal interaction behavior (e.g., withdrawing from interactions with the child and role-reversal, i.e., the takeover of the parental role or parts of it by the child) in mother-child-dyads can cause alteration of the child's stress response system. Higher salivary cortisol concentrations were reported in infants and toddlers directly after negative interactions with their parents. However, no study to date has examined the association between atypical maternal interaction behavior and hair cortisol concentrations (HCC) in infants. Here, we studied the association of maternal interaction behavior with HCC of the child. Mother-child dyads (N = 112) participated in the longitudinal study My Childhood-Your Childhood. The AMBIANCE scale and its subscales were used to assess atypical maternal interaction behavior during the Strange Situation Procedure. Chronic stress levels in the child were assessed by HCC of 3â cm hair strands at the age of 12 months. Maternal educational level (operationalized in highest education level) served as a control variable. Robust multiple linear regression analyses revealed that role/boundary confusion was associated with HCC, i.e., the higher atypical interaction behavior of the mother the higher the HCC in the children. By measuring hair cortisol in this study, it is possible to determine the average long-term activity of the child's stress response system.Thus, atypical maternal interaction behavior could be a risk factor for persistent stress in children, contributing to a higher risk for negative health outcomes in later life. The results of this study highlight the importance of early intervention programs that focus on the relationship between mother and child.
RESUMO
The Covid-19 pandemic has been profoundly affecting nearly everybody, but families with minors have been hit particularly. Closure of schools and kindergartens, home schooling, and working from home have led to a profound upheaval in family life. Parental adverse childhood experiences (ACEs) are an important determinant for parenting behavior. Importantly, ACEs can increase the vulnerability to stress and impair coping strategies. The current pandemic leads to increased parental stress, a risk factor for harsh parenting behavior, Therefore, we aimed to assess the role of ACEs and sociodemographic factors associated to parental coping during the current pandemic. In a cross-sectional online survey, 687 parents of minors in Germany were included. Demographic and psychosocial factors associated to parental coping during the first lockdown due to the Covid-19 pandemic were assessed. Results show that younger age of the respective child, income loss, dissatisfaction with the sharing of childcare duties, and ACEs were significantly associated with an increase of potential harmful parenting behavior during the Covid-19 pandemic. An increase of dissatisfaction with the sharing of childcare duties during the pandemic was predicted by working from home and taking care of the children mainly by oneself, while sharing childcare duties with the partner equally resulted even in an increase of satisfaction with sharing of childcare duties during the pandemic. These findings demonstrate that a history of childhood adversity in a parent is a risk factor for harmful parenting during the pandemic. Parental satisfaction with sharing of caregiving is an important factor for parental coping during the pandemic. Sharing of caregiving between partners should be encouraged.
RESUMO
The SARS-CoV-2-pandemic is associated different challenges, especially for families. The disruption and challenges require parents to develop strategies to cope with the current situation. One factor that may influence how parents deal with pandemic-associated stressors are experiences of parental childhood maltreatment (CM), which represent a high risk of engaging in endangered parenting. A decisive candidate for the connection between parental CM and the transgenerational transmission could be the parental ability to employ coping strategies. Mothers of a well-documented birth cohort for investigating the pathways leading to resilience or vulnerability in the transgenerational transmission of CM were imbedded in an online "SARS-CoV-2 pandemic survey" assessing maternal ability for coping strategies and the dimension of endangered maternal parenting behavior. 91 mothers completed the online survey. To describe the maternal CM, data from a longitudinal survey were used. Our mediation analysis shows a significant positive relationship between the sum of maternal CM experiences, lack of coping strategies and endangered parenting behavior. This suggests a partial mediation of the association between CM and endangered parenting behavior as the direct effect remained significant when the maternal lack of coping strategies was included as the mediator. Parental CM is a risk factor for coping with stressful situation as well as for endangered parenting behavior. The ability to deal with stress seems to have a significant influence on the context of a possible transgenerational transmission of CM. The results underline the need to consider the unique needs of families with children and to support them as to how to overcome the current crisis.
RESUMO
BACKGROUND: The current situation caused by the SARS-CoV-2-pandemic is associated with serious losses for everyone and has been affecting social life, politics, the economy and the media worldwide. Preventive isolation and social distancing strategies have confronted families with a large number of different challenges. The current epidemic and quarantine restrictions have a verifiable influence on the emotional and social development of children and adolescents. During this ongoing situation children of parents, who already were mentally stressed, seem particularly at risk. OBJECTIVE: We aimed to assess the role of maternal daily perceived stress on children's mental health during the SARS-CoV-2-pandemic. METHODS: An online "SARS-CoV-2-pandemic survey" was developed to assess children's mental health since the beginning of the SARS-CoV-2 pandemic. To describe maternal perceived everyday stress, data from a longitudinal survey was utilized. Our survey includes elements and versions of the Childhood Trauma Questionnaire, the Strengths and Difficulties Questionnaire and the Perceived Stress Scale. We furthermore collected socio-demographic data. Due to our limited dependent variables we applied Tobit models for estimation. RESULTS: We found a positive and significant effect of the maternal perceived everyday stress on children's emotional problems during the pandemic. Furthermore, results provide empirical evidence for an increase of the children's hyperactivity level dependent on the mother's perceived stress before the SARS-COV-2 crisis. We could not find significant effects for the relationship between mother's perceived everyday stress and the children's behavioral problems. CONCLUSIONS: Analyses illustrate the effects on children's mental distress during everyday life in the SARS-CoV-2 pandemic. Future research needs to identify influencing factors with regard to political, economic and social restrictions, in order to prevent children's mental health problems.
RESUMO
Background: The coronavirus disease 2019 (COVID-19) pandemic has changed the lives of families in an unprecedented way. During the first lockdown, extrafamilial contact was significantly reduced. Many parents had to look after their children and work from home while the economic pressure increased. Objective: The aim of the present study was to investigate the association between intimate partner violence (IPV) and mental health problems in children and adolescents before and during the COVID-19 pandemic. Material and methods: In a cross-sectional online survey 687 parents of underaged children in Germany were included. Demographic and psychosocial predictors for IPV and associations with mental health problems of children before and during the first lockdown due to the COVID-19 pandemic were assessed. The survey ran from 18 May 2020 to 21 July 2020 and the lockdown in Germany began on 23 March 2020 and ended via a gradual relaxation. The first schools reopened on 22 April and the opening of schools, kindergartens and daycare centers extended to the end of June 2020. Results: Lower household incomes and the experience of own adverse childhood experiences increased the risk of participants reporting violence in their relationship. According to the participating parents, children and adolescents living in families in which violence was reported by intimate partners were more likely to have higher levels of externalizing problems before and during the pandemic. There were no significant differences with respect to emotional problems. Conclusion: Adverse childhood experiences increase the risk of intimate partner violence, which in turn increases the risk of mental health problems in the children. Therefore, in the psychotherapeutic practice questions should also be systematically asked about corresponding experiences and appropriate treatment offers should be recommended.
RESUMO
BACKGROUND: Dysfunctional maternal behavior has been shown to lead to disturbances in infant's regulatory capacities and alterations in vagal reactivity. We aim to investigate the autonomic nervous system (ANS) response of the child during the strange situation procedure (SSP) in relation to the quality of maternal behavior. METHODS: Twelve month after birth, 163 mother-child-dyads were investigated during the SSP. Heart rate (HR) and both, the parasympathetic branch (PNS) via the respiratory sinus arrhythmia (RSA) and the sympathetic branch (SNS) via the left ventricular ejection time (LVET) of the ANS were continuously determined during the SSP using electrocardiogram (ECG) and impedance cardiogram (ICG) measures. Maternal behavior was assessed by using the AMBIANCE measure. RESULTS: The ANS response in infants of mothers with disruptive behavior compared to infants of non-disruptive mothers was significantly altered during the SSP: HR increased especially when infants of disruptive mothers were alone with the stranger (F (1, 161) = 4.15, p = .04) with a significant vagal withdrawal when being in contact with the stranger despite of presence of the mother (F (1, 161) = 5.11, p = .03) and a significant increase in vagal tone during final reunion (F (1, 161) = 3.76, p = .05). HR increase was mainly based on a decrease in LVET (F (1, 161) = 4.08, p = .05) with a maximum infant's HR when the stranger came into the room instead of the mother. CONCLUSION: Both, SNS and PNS branches of the child are significantly altered in terms of an ANS imbalance, especially during contract to a stranger, in relation to dysfunctional maternal behavior. Our findings suggest the importance of supporting high quality caregiving that enables the infant to adapt adequately to stressful interpersonal situations which is likely to promote later health.
