Post-adoption perinatal grief and parenting future children in the home: The moderating roles of social support and parental substance use.

Objective: The aim of this study was twofold: (a) to examine the impact of birth mother's post-adoption perinatal grief - stemming from ambiguous loss - on their perceptions of their parenting years later and the relationship quality they have with the children who they raise; and (b) to evaluate the potential contribution that social support and substance use severity play in moderating the impact of post-adoption perinatal grief.

Design: We applied an adoption design that consisted of a sample of birth mothers ( = 53) who placed one child for adoption at birth and parented another child in their home following the voluntary adoption placement of the adoptee. At 3-6 months postpartum of the adopted child, we measured birth mother's post-adoption perinatal grief, substance use severity, and level of social support received by their friends, family, and community.

A Moderated Mediation Model to Predict Adolescent Resistance to Peer Influence: Evidence From an Adoption Study.

Introduction: Adolescents are particularly susceptible to peer influence and at higher risk of engaging in problematic behaviors through peer interactions, but also vary in the extent to which they are influenced by their peers. Resistance to peer influence, the tendency to refuse undesired peer pressure, is one key factor for this variation. However, how genetic and contextual influences shape the development of RPI remain unclear.

Early-Life Factors and Body Mass Index Trajectories Among Children in the ECHO Cohort.

Importance: Identifying atypical body mass index (BMI) trajectories in children and understanding associated, modifiable early-life factors may help prevent childhood obesity.

Objective: To characterize multiphase BMI trajectories in children and identify associated modifiable early-life factors.

Design, Setting, And Participants: This cohort study included longitudinal data obtained from January 1997 to June 2024, from the Environmental influences on Child Health Outcomes (ECHO) cohort, which included children aged 1 to 9 years with 4 or more weight and height assessments.

Are Depressive and Anxiety Symptoms Differentially Associated with Alcohol Use Behaviors: Multivariate Behavioral Genetic Analyses.

This study examined whether adolescent depressive and anxiety symptoms were differentially associated with alcohol use behaviors, and how these associations were explained by genetic, shared, and nonshared environmental influences. Participants were from the Nonshared Environment and Adolescent Development project of same-sex twin/sibling pairs from 720 families. Twin/sibling depressive and anxiety symptoms were measured by self-report at Time 1 (M = 13.

Adolescent Social Media Use and Mental Health in the Environmental Influences on Child Health Outcomes Study.

Purpose: Research on adolescent social media use focuses on negative mental health outcomes, with less attention on potential positive outcomes. The current study addresses this limitation by investigating associations between adolescent social media use and both psychological well-being and psychopathology.

Methods: Three US-based pediatric cohort sites participating in the National Institutes of Health Environmental influences on Child Health Outcomes study contributed cross-sectional survey data.

Connecting parents' developmental history to family life: Marital instability after the journey of infertility for adoptive parents.

Parents bring their preparenthood experiences into their family relationships, which may have a persistent impact on family dynamics. One such significant experience is infertility, often shared by both partners but differentially experienced by women and men. Using a prospective longitudinal study of adoptive parents with a history of infertility challenges who later adopted a child ( = 461, 91% White), we aimed to (a) examine the impact of preparenthood infertility distress on heterosexual couples' perceived marital instability trajectories in the 11 years of parenthood and (b) test whether social support from their partner and other sources would moderate the impact of infertility distress.

Children's executive functioning and health behaviors across pediatric life stages and ecological contexts.

Executive functioning (EF) has been linked to chronic disease risk in children. Health behaviors are thought to partially explain this association. The current cross-sectional study evaluated specific domains of EF and varied health behaviors in three pediatric life stages.

A descriptive examination of rurality in the Environmental influences on Child Health Outcomes Cohort: Implications, illustrations, and future directions.

Purpose: The Environmental influences on Child Health Outcomes (ECHO) Cohort has enrolled over 60,000 children to examine how early environmental factors (broadly defined) are associated with key child health outcomes. The ECHO Cohort may be well-positioned to contribute to our understanding of rural environments and contexts, which has implications for rural health disparities research. The present study examined the outcome of child obesity to not only illustrate the suitability of ECHO Cohort data for these purposes but also determine how various definitions of rural and urban populations impact the presentation of findings and their interpretation.

Extending the Environmental influences on Child Health Outcomes (ECHO) Cohort through 2030: Rationale and study protocol.

Early life environmental exposures, even those experienced before conception, can shape health and disease trajectories across the lifespan. Optimizing the detection of the constellation of exposure effects on a broad range of child health outcomes across development requires considerable sample size, transdisciplinary expertise, and developmentally sensitive and dimensional measurement. To address this, the National Institutes of Health (NIH) Environmental influences on Child Health Outcomes (ECHO) Cohort Study is an observational longitudinal pediatric cohort study.

Lability in parent-child warmth and hostility and adolescent externalizing behaviors.

Both longer term developmental changes (increases in hostility, decreases in warmth) and lability (year-to-year fluctuations) in parent-child relationship quality across childhood and adolescence have been linked to adolescent externalizing behaviors. Using a prospective longitudinal study of 561 children who were adopted into nonrelative families at birth (57% male, 56% White, 19% multiracial, 13% Black, 11% Hispanic) where parental warmth and hostility reflect environmental influences or child-evoked reactions, we examined associations between parent-child relationship measures and externalizing behaviors at age 11 and across adolescence (i.e.

The importance of family-based sampling for biobanks.

Biobanks aim to improve our understanding of health and disease by collecting and analysing diverse biological and phenotypic information in large samples. So far, biobanks have largely pursued a population-based sampling strategy, where the individual is the unit of sampling, and familial relatedness occurs sporadically and by chance. This strategy has been remarkably efficient and successful, leading to thousands of scientific discoveries across multiple research domains, and plans for the next wave of biobanks are underway.

Intergenerational transmission of comorbid internalizing and externalizing psychopathology at age 11: Evidence from an adoption design for general transmission of comorbidity rather than homotypic transmission.

Psychopathology is intergenerationally transmitted through both genetic and environmental mechanisms via heterotypic (cross-domain), homotypic (domain-specific), and general (e.g., "p-factor") pathways.

Biospecimens in the HEALthy Brain and Child Development (HBCD) Study: Rationale and protocol.

The HEALthy Brain and Child Development (HBCD) Study, a multi-site prospective longitudinal cohort study, will examine human brain, cognitive, behavioral, social, and emotional development beginning prenatally and planned through early childhood. The longitudinal collection of biological samples from over 7000 birthing parents and their children within the HBCD study enables research on pre- and postnatal exposures (e.g.

The dynamic and relational nature of parent-child conflict from childhood into emerging adulthood.

Although the parent-child relationship is widely regarded as a foundational context for youth development, the developmental origins of this relationship remain unknown. The present study addressed these gaps, leveraging longitudinal and genetically informed methods to illuminate the developmental origins of mother-child conflict as it unfolds from middle childhood into emerging adulthood. Participants consisted of 2,060 twins in 1,030 twin families (51% male, 49% female; 82% White, 10% Black, 1% Asian, 1% Indigenous, 6% multiracial) from the Michigan State University Twin Registry.

Early risk for child externalising symptoms: Examining genetic, prenatal, temperamental and parental influences.

This study utilized the Early Growth and Development Study (N = 561 adoptive children; 57.2% male, 55.3% White), a study of children adopted at birth, to examine heritable (birth parent psychopathology) and prenatal risk (prenatal maternal distress and smoking during pregnancy), infant negative affectivity, adoptive parent over-reactivity and warmth as independent predictors of childhood externalizing symptoms.

Stronger color evasive racial ideologies predict lower likelihood of open adoption placement with same-sex couples.

Although the adoption rate among same-sex couples has been increasing, limited research has focused on factors influencing decision making related to placing children with such couples, particularly from the standpoint of birth mothers. Additionally, there is a gap in the literature regarding how biases may influence birth mothers' decision to place their child with a same-sex couple. This study sought to examine the association between birth mothers' racial ideologies and their decision to voluntarily place their children with same-sex couples ( = 29) or mother-father couples ( = 354) during the adoption process.

Integrating the family stress model within a longitudinal sibling-adoption study of adolescent externalizing behavior.

Using a sample of linked adopted children, adoptive and birth parents (N = 561), and biological siblings residing in the birth parent home (N = 191), we examined the role of genetics within family stress processes. We tested parental hostility (7 years) as a mediator of the associations between socioeconomic strain and rearing parent psychopathology (4 years) and adolescent externalizing behaviors (11 years) in adoptive and biological parent homes. Next, we examined parent social support (4 years) as a moderator of paths from socioeconomic strain and parent psychopathology to parental hostility.

Evocative effects on the early caregiving environment of genetic factors underlying the development of intellectual and academic ability.

This study examined gene-environment correlation (rGE) in intellectual and academic development in 561 U.S.-based adoptees (57% male; 56% non-Latinx White, 19% multiracial, 13% Black or African American, 11% Latinx) and their birth and adoptive parents between 2003 and 2017.

The effects of illicit drug use during pregnancy and parental hostility on problem behaviors in school-aged children over and above genetic influences.

Previous work has examined the impact of prenatal illicit drug use (PDU) on children's problem behaviors. However, many PDU-related risk factors, including genetic and rearing environmental risks, can also influence offspring's problem behaviors, thus confounding PDU, genetic, and rearing environmental influences. This study aimed to (a) identify effects of PDU on school-aged children's problem behaviors, including both externalizing and internalizing behaviors at Age 7, after controlling genetic and specific rearing environmental (e.

Developmental trajectories of child and adolescent emotional problems: associations with early adult alcohol use behaviors.

Background: Whether emotional problems during childhood and adolescence are longitudinally associated with adult alcohol use behaviors is unclear. This study examined associations between developmental trajectories of emotional problems and early adult alcohol use behaviors, while considering co-occurring conduct problems, developmental change/timing, sex differences, and potential confounds.

Methods: Participants were from the Twins Early Development Study (analytic N = 19,908 individuals).

Influence of early childhood parental hostility and socioeconomic stress on children's internalizing symptom trajectories from childhood to adolescence.

Introduction: Children and adolescents with elevated internalizing symptoms are at increased risk for depression, anxiety, and other psychopathology later in life. The present study examined the predictive links between two bioecological factors in early childhood-parental hostility and socioeconomic stress-and children's internalizing symptom class outcomes, while considering the effects of child sex assigned at birth on internalizing symptom development from childhood to adolescence.

Materials And Methods: The study used a sample of 1,534 children to test the predictive effects of socioeconomic stress at ages 18 and 27 months; hostile parenting measured at child ages 4-5; and sex assigned at birth on children's internalizing symptom latent class outcomes at child ages 7-9, 10-12, 13-15, and 16-19.

The Detection of Environmental Influences on Academic Achievement Appears to Depend on the Analytic Approach.

One long-standing analytic approach in adoption studies is to examine correlations between features of adoptive homes and outcomes of adopted children (hereafter termed 'measured environment correlations') to illuminate environmental influences on those associations. Although results from such studies have almost uniformly suggested modest environmental influences on adopted children's academic achievement, other work has indicated that adopted children's achievement is routinely higher than that of their reared-apart family members, often substantially so. We sought to understand this discrepancy.

Child effects on positive parenting vary with neighborhood opportunity.

Prior theoretical and empirical research has highlighted links between positive parenting and the socioeconomic characteristics of the family's neighborhood, but has yet to illuminate the etiologic origins of this association. One possibility is that the various predictors of parenting outlined by Belsky (1984; e.g.

The role of fathers in child development from preconception to postnatal influences: Opportunities for the National Institutes of Health Environmental influences on Child Health Outcomes (ECHO) program.

A growing body of literature highlights the important role of paternal health and socioemotional characteristics in child development, from preconception through adolescence. Much of this research addresses the indirect effects of fathers, for instance, their influence on maternal behaviors during the prenatal period or via the relationship with their partner. However, emerging evidence also recognizes the direct role of paternal health and behavior for child health and adjustment across development.

The pernicious role of stress on intergenerational continuity of psychopathology.

has been a premier resource for understanding stressful childhood experiences and the intergenerational continuity of psychopathology. Building on that tradition, we examined the unique and joint influences of maternal stress on children's effortful control (age 7) and externalizing behavior (age 11) as transmitted via genetics, the prenatal environment, and the postnatal environment. The sample included = 561 adopted children and their biological and adoptive parents.
