Parent versus child influences on differential parent warmth and discipline within twin pairs.

Parenting behaviors have long been recognized as crucial to children's healthy development. However, examinations of the etiology of these behaviors are less prevalent. The current study investigated the driving forces behind parental warmth and discipline, particularly whether they are related more to traits within the parent or reactions to characteristics of the child. To explore this question, three robust factors of child temperament-effortful control, negative affectivity, and surgency/extraversion-and five parent personality traits were examined in association with parent behaviors through differential parenting within 185 four-year-old twin pairs (370 children; 56% girls; 90% White; predominantly middle class). Genetic analyses showed that parents tend to treat both children similarly in terms of parental warmth, but they treat children less similarly in terms of discipline, regardless of child zygosity. Multilevel linear regressions showed that within twin pairs, the child with higher effortful control received less discipline from parents than their cotwin. Analyses also showed that parent agreeableness was significantly related to parent warmth above and beyond other personality traits and child temperament. This study clarified the direction of effects and genetic contributions to parenting behaviors, supporting previous literature that discipline acts in reaction to the child, whereas warmth is more driven by parent personality. This research suggests the importance of focusing on child temperament and parent personality as they relate to parenting behaviors, allowing clinicians and parents to more effectively correct maladaptive parenting behaviors and encourage healthy and adaptive parenting behaviors, thus promoting positive outcomes for children.

Nurturing care during COVID-19: a rapid review of early evidence.

OBJECTIVES: The COVID-19 pandemic has brought significant changes to family life, society and essential health and other services. A rapid review of evidence was conducted to examine emerging evidence on the effects of the pandemic on three components of nurturing care, including responsive caregiving, early learning, and safety and security. DESIGN: Two academic databases, organisational websites and reference lists were searched for original studies published between 1 January and 25 October 2020. A single reviewer completed the study selection and data extraction with verification by a second reviewer. INTERVENTIONS: We included studies with a complete methodology and reporting on quantitative or qualitative evidence related to nurturing care during the pandemic. PRIMARY AND SECONDARY OUTCOME MEASURES: Studies reporting on outcomes related to responsive caregiving, early learning, and safety and security were included. RESULTS: The search yielded 4410 citations in total, and 112 studies from over 30 countries met our eligibility criteria. The early evidence base is weighted towards studies in high-income countries, studies related to caregiver mental health and those using quantitative survey designs. Studies reveal issues of concern related to increases in parent and caregiver stress and mental health difficulties during the pandemic, which was linked to harsher and less warm or responsive parenting in some studies. A relatively large number of studies examined child safety and security and indicate a reduction in maltreatment referrals. Lastly, studies suggest that fathers' engagement in caregiving increased during the early phase of the pandemic, children's outdoor play and physical activity decreased (while screen time increased), and emergency room visits for child injuries decreased. CONCLUSION: The results highlight key evidence gaps (ie, breastfeeding support and opportunities for early learning) and suggest the need for increased support and evidence-based interventions to ensure young children and other caregivers are supported and protected during the pandemic.

Birth Complications and Negative Emotionality Predict Externalizing Behaviors in Young Twins: Moderations with Genetic and Family Risk Factors.

We examined interactions among genetic, biological, and ecological variables predicting externalizing behaviors in preschool and middle childhood. Specifically, we examined prediction of externalizing behaviors from birth complications and negative emotionality, each moderated by genetic risk for aggression and ecological risk factors of insensitive parenting and low family income. At ages 4 and 5 years, 170 twin pairs and 5 triplet sets (N = 355 children) were tested; 166 of those children were tested again at middle childhood (M = 7.9 years). Multilevel linear modeling results showed generally that children at high genetic risk for aggression or from low-income families were likely to have high scores on externalizing, but for children not at high risk, those with increased birth complications or more negative emotionality had high scores on externalizing. This study underscores the importance of considering biological variables as moderated by both genetic and ecological variables as they predict externalizing behaviors across early childhood.
