Zelfregulatie: Resultaat van opvoeding en biologie?

Kinderen die al op jonge leeftijd in staat zijn om hun gedrag en hun emoties te controleren en te sturen, vertonen minder vaak gedragsproblemen en functioneren op latere leeftijd beter in sociale situaties en op school. In dit artikel wordt enerzijds beschreven hoe ouders de ontwikkeling van zelfregulatie bij hun kinderen kunnen beïnvloeden, via de kwaliteit van de relatie met hun kind en via specifiek opvoedgedrag. Anderzijds wordt het complexe samenspel tussen biologische processen en de opvoedingsomgeving in de ontwikkeling van zelfregulatie bij jonge kinderen belicht. De kwaliteit van de ouder-kindrelatie en de mate van sensitiviteit en positieve disciplinering blijken gerelateerd te zijn aan de mate waarin peuters en kleuters hun emoties, gedrag en denken kunnen reguleren. Deze relaties tussen opvoeding en zelfregulatie blijken echter deels afhankelijk van de hersenontwikkeling en genetische bagage van de kinderen. De mogelijke manieren waarop opvoeding de ontwikkeling van zelfregulatie kan beïnvloeden worden besproken en relevante interventies worden belicht

Kweek je een leugenaar door te liegen tegen je kind?

Welk effect heeft liegen tegen je kinderen in de opvoeding? En is de ene leugen ‘erger’ dan de andere? Rianne Kok, expert op het gebied van sociaal-emotionele ontwikkeling, verbonden aan de Erasmus Universiteit Rotterdam, deed onderzoek naar het effect van liegen op kinderen. Ook het onderzoek van de Amerikaanse psychologieprofessor Gail Heyman, komt ter sprake, waaruit blijkt dat liegen door ouders, wel degelijk effect heeft op hun kinderen

No differential susceptibility or diathesis stress to parenting in early adolescence: Personality facets predicting behaviour problems

This multi-sample study investigated the main and interactive effects of parenting (responsiveness, overreactivity) and young adolescents' personality traits (negative-affectivity: irritability and anxiety; and orienting-sensitivity) on behaviour problems during adolescence. Data from two samples (N1 = 222; girls 45.5%; Mean age = 11.54 years; N2 = 252; girls 50.4%; Mean age = 10.85 years) were analysed using a multivariate approach. Parenting and y

Socialization of prosocial behavior: Gender differences in the mediating role of child brain volume

Evidence has been accumulating for the impact of normal variation in caregiving quality on brain morphology in children, but the question remains whether differences in brain volume related to early caregiving translate to behavioral implications. In this longitudinal population-based study (N = 162), moderated mediation was tested for the relation between parental sensitivity and child prosocial behavior via brain volume, in boys and girls. Both maternal and paternal sensitivity were repeatedly observed between 1 and 4 years of age. Brain volume was assessed using magnetic resonance imaging measurements at age 8, and self-reported prosocial behavior of children was assessed at 9 years of age. Parental sensitivity was positively related to child brain volume, and to child prosocial behavior at trend level. Child brain volume was negatively related to child prosocial behavior. A significant gender-by-brain interaction was found, illustrating that daughters of sensitive parents were more prosocial and that less prosocial behavior was reported for girls with a larger total brain volume. Child gender significantly moderated the indirect effect of parental sensitivity on prosocial behavior via total brain volume. A significant indirect pathway was found only in girls. The results warrant replication but indicate the importance of considering gender when studying the behavioral implications of differences in brain volume related to early caregiving experiences

Gastrointestinal Symptoms in Infants of Mothers with a Psychiatric History and the Role of Depression and Bonding

Objectives: Gastroesophageal reflux (GER), excessive crying, and constipation are common gastrointestinal symptoms in infancy of multifactorial origin in which psychosocial stress factors play an important role. The aims of this observational study were to investigate the presence of gastrointestinal symptoms in infants of mothers with or without a history of a psychiatric disorder, their association with maternal depressive symptoms, and the possible mediating role of bonding. Methods: 101 mothers with a history of a psychiatric disorder (“PD mothers”) and 60 control mothers were included. Infant gastrointestinal symptoms, maternal depressive symptoms, and mother-infant bonding were assessed using validated questionnaires and diagnostic criteria at 1.5 month postpartum. Results: The mean total score on the Infant Gastroesophageal Reflux Questionnaire Revised (I-GERQ-R) reported in infants of PD mothers (13.4 SD 5.4) was significantly higher than in infants of control mothers (10.8 SD 5.4; P =.003). No significant differences were found in the presence of excessive crying (modified Wessel’s criteria and subjective experience) and constipation (ROME IV criteria) between both groups. Infant GER was associated with maternal depressive symptoms (P = 0.027) and bonding problems (P = <0.001). Constipation was related to maternal depressive symptoms (P = 0.045), and excessive crying (Wessel and subjective criteria) was associated with bonding problems (respectively P = 0.022 and P = 0.002). The effect of maternal depressive symptomatology on infant GER symptoms and excessive crying was mediated by bonding problems. Conclusion: Maternal psychiatric history is associated with infant gastrointestinal symptoms, in which mother-infant bonding is a mediating factor

Targeted social care for highly vulnerable pregnant women: Protocol of the Mothers of Rotterdam cohort study

Introduction: Social vulnerability is known to be related to ill health. When a pregnant woman is socially vulnerable, the ill health does not only affect herself, but also the health and development of her (unborn) child. To optimise care for highly vulnerable pregnant women, in Rotterdam, a holistic programme was developed in close collaboration between the university hospital, the local government and a non-profit organisation. This programme aims to organise social and medical care from pregnancy until the second birthday of the child, while targeting adult and child issues simultaneously. In 2014, a pilot in the municipality of Rotterdam demonstrated the significance of this holistic approach for highly vulnerable pregnant women. In the Mothers of Rotterdam' study, we aim to prospectively evaluate the effectiveness of the holistic approach, referred to as targeted social care. Methods and analysis: The Mothers of Rotterdam study is a pragmatic prospective cohort study planning to include 1200 highly vulnerable pregnant women for the comparison between targeted social care and care as usual. Effectiveness will be compared on the following outcomes: (1) child development (does the child show adaptive development at year 1?) and (2) maternal mental health (is maternal distress reduced at the end of the social care programme?). Propensity scores will be used to correct for baseline differences between both social care programmes. Ethics and dissemination: The prospective cohort study was approved by the Erasmus Medical Centre Ethics Committee (ref. no. MEC-2016-012) and the first results of the study are expected to be available in the second half of 2019 through publication in peer-reviewed international journals.

The Longitudinal Relation between Observed Maternal Parenting in the Preschool Period and the Occurrence of Child ADHD Symptoms in Middle Childhood

In this longitudinal population-based cohort (N = 547) we examined the relation between maternal discipline and sensitivity in the preschool period and the occurrence of attention-deficit hyperactivity disorder (ADHD) symptoms in middle childhood, taking into account pre-existing child attention and executive function (EF) problems, and oppositional defiant disorder (ODD) symptom comorbidity. Maternal parenting was observed during a \xe2\x80\x98do not touch task\xe2\x80\x99 (positive and negative discipline) and a teaching task (sensitivity) at age 3. Parents reported on the occurrence of ADHD and ODD symptoms at age 8 using the Conners\xe2\x80\x99 Parent Rating Scale. Attention and executive function problems were assessed using parent questionnaires at age 4. Important covariates such as harsh discipline and maternal depression were also taken into account. Maternal sensitivity significantly predicted later ADHD symptoms beyond pre-existing child attention and EF problems, and comorbid ODD symptoms. However, maternal negative and positive discipline did not significantly predict later ADHD symptoms over and above these covariates. This study demonstrates the importance of maternal sensitivity in the etiology of core ADHD symptoms above and beyond pre-existing child attention and EF problems, and comorbid ODD symptoms

Epigenome-wide associations between observed maternal sensitivity and offspring DNA methylation

Background Experimental work in animals has shown that DNA methylation (DNAm), an epigenetic mechanism regulating gene expression, is influenced by typical variation in maternal care. While emerging research in humans supports a similar association, studies to date have been limited to candidate gene and cross-sectional approaches, with a focus on extreme deviations in the caregiving environment. Methods Here, we explored the prospective association between typical variation in maternal sensitivity and offspring epigenome-wide DNAm, in a population-based cohort of children (N = 235). Maternal sensitivity was observed when children were 3-and 4-years-old. DNAm, quantified with the Infinium 450 K array, was extracted at age 6 (whole blood). The influence of methylation quantitative trait loci (mQTLs), DNAm at birth (cord blood), and confounders (socioeconomic status, maternal psychopathology) was considered in follow-up analyses. Results Genome-wide significant associations between maternal sensitivity and offspring DNAm were observed at 13 regions (p < 1.06 × 10-07), but not at single sites. Follow-up analyses indicated that associations at these regions were in part related to genetic factors, confounders, and baseline DNAm levels at birth, as evidenced by the presence of mQTLs at five regions and estimate attenuations. Robust associations with maternal sensitivity were found at four regions, annotated to ZBTB22, TAPBP, ZBTB12, and DOCK4. Conclusions These findings provide novel leads into the relationship between typical variation in maternal caregiving and offspring DNAm in humans, highlighting robust regions of associations, previously implicated in psychological and developmental problems, immune functioning, and stress responses
