How Heritable are Parental Sensitivity and Limit-Setting? A Longitudinal Child-Based Twin Study on Observed Parenting.

We examined the relative contribution of genetic, shared environmental and non-shared environmental factors to the covariance between parental sensitivity and limit-setting observed twice in a longitudinal study using a child-based twin design. Parental sensitivity and parental limit-setting were observed in 236 parents with each of their same-sex toddler twin children (Mage  = 3.8 years; 58% monozygotic). Bivariate behavioral genetic models indicated substantial effects of similar shared environmental factors on parental sensitivity and limit-setting and on the overlap within sensitivity and limit-setting across 1 year. Moderate child-driven genetic effects were found for parental limit-setting in year 1 and across 1 year. Genetic child factors contributing to explaining the variance in limit-setting over time were the same, whereas shared environmental factors showed some overlap.

Behavioral genetics of temperament and frontal asymmetry in early childhood.

Temperament has been suggested to be influenced by genetic and environmental factors. The current study examined genetic shared environmental and unique environmental factors accounting for variation in Fear, Effortful Control (EC), and Frontal Asymmetry (FA) in 4- to 6-year-old children using bivariate behavioral genetic modeling. We included a total of 214 same-sex twin pairs: 127 monozygotic (MZ) and 87 dizygotic (DZ) pairs. FA was measured during a rest electroencephalogram (EEG) recording, and Fear and EC were measured using parent report. Results show that differences between twins were best explained by genetic factors (about a quarter of the variance) and unique environmental factors (about three quarters of the variance). However, the cross-trait, within-twin correlations were not significant, implying no overlapping genetic or environmental factors on Fear and EC or on Fear and FA. Future research should try to elucidate the large role of unique environmental factors in explaining variance in these temperament-related traits.

The Prosocial Cyberball Game: Compensating for social exclusion and its associations with empathic concern and bullying in adolescents.

In this study we examined prosocial compensating behavior towards socially excluded ingroup and outgroup members by using a 'Prosocial Cyberball Game' in 9-17 year old Dutch adolescents (N = 133). Results showed that adolescents compensated for the social exclusion of an unknown peer in a virtual ball tossing game, by tossing the ball more often to that player in compensation conditions compared to the fair play condition. The proportion of tosses towards the excluded player did not significantly differ as a function of the group status of that player. Although compensating behavior towards ingroup versus outgroup members did not differ, the underlying motivation for this behavior may vary. More empathic concern was associated with more prosocial tosses towards an ingroup member, while more self-reported bullying behavior was associated with less compensating behavior in the outgroup condition. These findings may have practical implications for programs intending to change bystander behavior in bullying situations.

Replicating a randomized trial with video-feedback to promote positive parenting in parents of school-aged twins.

In this randomized controlled trial, we investigated the effectiveness of the brief, home-based Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD) in parents of 257 school-aged twin pairs (N = 514 children, Mage = 7.92, SD = 0.66), replicating a previous study testing the effectiveness of the intervention in parents with preschool-aged twins (Euser et al., 2021). We conducted two pretests (1 year apart) and one posttest 1 month after the intervention. An age-adequate twin-adapted version of the VIPP-SD was used in primary caregivers (91% female). We examined the main effect of the intervention on observed parental sensitivity and sensitive discipline and on attitudes toward sensitivity and sensitive discipline. We also investigated whether parents who are more susceptible to the environment, as measured by their self- and partner-reported current temperamental reactivity, benefitted more from the intervention. In our sample with older children, the VIPP-SD did not significantly change observed parental sensitivity or sensitive discipline in the intervention group compared to the control group. The VIPP-SD did improve parents' attitude toward sensitivity, but not toward discipline. Intervention effects were not moderated by temperamental reactivity of the parents, providing no support for the differential susceptibility hypothesis. Future research might examine the differential susceptibility hypothesis in parents using stress-reactivity or genetic susceptibility markers instead of self-reported reactive temperament.

Video-feedback promotes sensitive limit-setting in parents of twin preschoolers: a randomized controlled trial.

BACKGROUND: Primary aim of the current randomized controlled trial was to test the effectiveness of the parenting intervention 'Video-feedback to promote Positive Parenting and Sensitive Discipline' (VIPP-SD) in a sample of parents of preschool-aged twins, as well as differential susceptibility to intervention efforts, that is, whether more temperamentally reactive parents would profit more from the VIPP-SD than parents with lower reactivity. METHODS: The sample consisted of 202 families with same-sex twins [N = 404 children, mean age 45 months (SD = 6.81)]. Randomization was done at the family level in a 2:3 ratio, with 83 families (41%) randomized to the VIPP-SD group, and 119 families (59%) to the control group. After two pre-tests in year 1 and year 2 of the study, the VIPP-SD was implemented in the third year, with a post-test assessment 1 month after the five intervention sessions. Parental sensitivity was observed during structured play in which parent and child copied a drawing together in a computerized Etch-A-Sketch paradigm. Parental limit-setting was observed in a 'don't touch' task in which the parent required from the child to abstain from playing with attractive toys. Parents interacted with each of their twins in separate sessions. RESULTS: The VIPP-SD intervention had a positive impact on the level of parents' positive limit-setting in interaction with their preschool twins, and this positive effect was most pronounced when the parents completed at least five intervention sessions. However, the intervention did not enhance parental sensitivity during structured play. Parents with higher reactivity were not more open to the impact of the intervention, thus for this temperamental marker differential susceptibility in adults was not supported. CONCLUSIONS: The current study is unique in targeting families with twin preschoolers, providing proof of principle that coaching parents with video-feedback promotes parental sensitive limit-setting to both children. It remains to be seen whether this finding can be replicated in families with non-twin siblings, or other parental susceptibility markers. Trial registration Trial NL5172 (NTR5312), 2015-07-20.

Child Care in Times of COVID-19: Predictors of Distress in Dutch Children and Parents When Re-entering Center-Based Child Care After a 2-Month Lockdown.

As a consequence of the outbreak of the Coronavirus Disease 2019 (COVID-19) child care facilities all over the world were temporarily closed to minimize the spread of the virus. In Netherlands, the first closure lasted for almost 2 months. The return to the child care center after this significant interruption was expected to be challenging, because earlier studies demonstrated that transitions into child care can be stressful for both children and their parents. The current paper retrospectively examined the distress of Dutch children (aged 0-4) and their parents during the first 2 weeks after the reopening of child care centers, and what factors accounted for individual differences in distress. In total, 694 parents filled out an online questionnaire about stress during closure and distress after the reopening of child care centers. Furthermore, questions regarding several demographic variables and child care characteristics were included, as well as questionnaires measuring child temperament, parental separation anxiety, and parental perception of the child care quality. Results showed that younger children and children with parents scoring higher on separation anxiety experienced more distress after the reopening, as reported by parents. Furthermore, children were more distressed upon return when they attended the child care center for less hours per week after the reopening, experienced less stress during closure, and grew up in a one-parent family. With regard to parental distress after the reopening, we found that parents scoring higher on separation anxiety and fear of COVID-19 experienced more distress. Moreover, parents experiencing less stress during closure and mothers were more distressed when the child returned to the child care center. Finally, concurrent child and parental distress after reopening were positively related. The results of the current study may help professional caregivers to identify which children and parents benefit from extra support when children return to the child care center after an interruption. Especially the role that parental separation anxiety played in predicting both child and parental distress deserves attention. More research is required in order to study the underlying mechanisms of these associations and to design appropriate interventions.

Effects of the Video-feedback intervention to promote positive parenting and sensitive discipline on mothers' neural responses to child faces: A randomized controlled ERP study including pre- and post-intervention measures.

Parenting interventions have proven to be effective in enhancing positive parenting behavior and child outcomes. However, the neurocognitive mechanisms explaining the efficacy remain largely unknown. We tested effects of the Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD) on mothers' neural processing of child faces. Our primary focus was on the N170 and the secondary focus on the LPP. We expected the intervention to enhance the amplitudes of both ERP components in response to emotional compared to neutral faces. A total of 66 mothers visited the lab for two identical sessions separated by 4.28 months (SD = 0.86) during which a random 33% of the mothers received the VIPP-SD. During both pre- and post-intervention sessions, mothers' electroencephalographic (EEG) activity in response to photographs of children's neutral, happy and angry facial expressions were acquired. In contrast to our expectations, we found smaller (less negative) N170 amplitudes at post-test in the intervention group. There was no intervention effect on the LPP, although overall LPP amplitudes were more positive for neutral and angry compared to happy faces. Our study shows that the N170 is affected by the VIPP-SD, suggesting that the intervention promotes efficient, less effortful face processing.Trial registration: Dutch Trial Register: NTR5312; Date registered: 3 January 2017.

Effects of parental sensitivity in different contexts on children's hot and cool effortful control.

To thrive as an individual and within society, children need to develop the ability to control their behavior. Using a twin design, we estimated the relative influence of genetic, shared, and unique environmental factors on hot and cool effortful control (EC). Furthermore, we investigated whether parental sensitivity in a play, task, or discipline context when the children were on average 3.78 years old, was differentially related to children's hot and cool EC 1 year later (Mage 4.77 years). We included 476 children from 238 twin pairs (48% boys, 58% monozygotic) and their primary parent. Hot EC (delay of gratification) was measured with the marshmallow test and cool EC (response inhibition) was measured with a stop-signal task. The behavioral genetics analyses showed that individual differences in hot and cool EC were mostly explained by unique environmental factors, whereas their association was mostly explained by shared environmental factors. Controlling for sensitivity in the other contexts, task sensitivity contributed to the prediction of cool EC, and sensitive discipline contributed to both cool and hot EC. Play sensitivity did not contribute to the prediction of hot or cool EC over and above parental sensitivity in the other contexts. Our study contributes to a better understanding of the unique and shared antecedents of hot and cool EC, suggesting parental sensitive discipline as a focus for preventive interventions targeting both hot and cool EC.

Stressful family environments and children's behavioral control: A multimethod test and replication study with twins.

Young children's behavioral control predicts a broad range of developmental outcomes in child- and adulthood. It is therefore important to study how individual differences in behavioral control arise. Previous studies suggest that there are both genetic and environmental influences, which were estimated in the current study using a sample of mono- and dizygotic same-sex twins. Furthermore, we examined the associations between indicators of a stressful family environment like household chaos, parenting daily hassles, and parental depressive symptoms and children's behavioral control in 2 samples. Children of the same twin pair were randomly divided over 2 samples; a test (N = 201, 48.3% boys, M age 46.53 months) and replication sample (N = 201, 49.8% boys, M age 46.06 months). Both parents reported on their children's effortful control via the Child Behavior Questionnaire and children's cheating behavior was observed during a throwing game. We found that AE models fitted the data for effortful control (A = 31%, E = 69%) and cheating (A = 16%, E = 84%) best. Path analyses revealed that children of parents experiencing more parenting daily hassles and depressive symptoms had lower levels of effortful control in the test sample. Furthermore, we found that children growing up in more chaotic households (parent report) had an increased risk of being in the cheating group versus the possible intention to cheat group in the test sample. These results were partially replicated. We suggest that the role of stressful family environments in the development of behavioral control should be considered when setting up prevention and intervention programs targeting children's behavioral control.

Efficacy of the Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline in Twin Families (VIPP-Twins): Study protocol for a randomized controlled trial.

BACKGROUND: Intervention programs with the aim of enhancing parenting quality have been found to be differentially effective in decreasing negative child outcomes such as externalizing behavioral problems, resulting in modest overall effect sizes. Here we present the protocol for a randomized controlled trial to examine the efficacy of the Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline for Twin Families (VIPP-Twins) on parenting quality and children's behavioral control and social competence. In addition, we aim to test the differential susceptibility theory; we examine differential efficacy of the intervention based on genetic make-up or temperament for both parents and children. Lastly, we explore neurobiological mechanisms underlying intervention effects on children's developmental outcomes. METHODS/DESIGN: The original VIPP-SD was adapted for use in families with twins. The VIPP-Twins consists of five biweekly sessions in which the families are visited at home, parent-child interactions are videotaped and parents receive positive feedback on selected video fragments. Families (N = 225) with a same sex twin (mean age = 3.6 years) were recruited to participate in the study. The study consists of four assessments. After two baseline assessments in year 1 and year 2, a random 40 % of the sample will receive the VIPP-Twins program. The first post-test assessment will be carried out one month after the intervention and there will be a long term follow-up assessment two years after the intervention. Measures include observational assessments of parenting and children's social competence and behavioral control, and neurobiological assessments (i.e., hormonal functioning and neural (re-)activity). DISCUSSION: Results of the study will provide insights in the efficacy of the VIPP-Twins and reveal moderators and mediators of program efficacy. Overall the randomized controlled trial is an experimental test of the differential susceptibility theory. TRIAL REGISTRATION: Dutch Trial Register: NTR5312 ; Date registered: July 20, 2015.
