Description
This study investigated whether the patterns of direct association, and of gene-environment interaction (GxE), between family variables (i.e., parenting, family conflict, and attitudinal familism) and youth externalizing behaviors differed across racial/ethnic groups. The sample was composed of 772 twin pairs

This study investigated whether the patterns of direct association, and of gene-environment interaction (GxE), between family variables (i.e., parenting, family conflict, and attitudinal familism) and youth externalizing behaviors differed across racial/ethnic groups. The sample was composed of 772 twin pairs from the Adolescent Brain Development Study (ABCD) and analyses were run on three racial/ethnic groups (White [n=1023], Black/African American [n=220], Hispanic [n=152]; Mage=10.14 years). Youth reports of parental warmth, parental monitoring, family conflict, parent-reported attitudinal familism, and parent reports of youth externalizing behaviors were collected at baseline when children were 10 years old. Regression analyses tested the direct association between the family variables and youth externalizing behaviors, and moderated heritability models tested for GxE. Family conflict was associated with more externalizing behaviors for White youth, and parental warmth was associated with fewer externalizing behaviors for Hispanic youth. Parental attitudinal familism composite and familism support were associated with fewer externalizing behaviors for Black youth but more externalizing behaviors for Hispanic youth. We found no effects for parental monitoring, familism obligations, and familism referent on youth externalizing behaviors. Additive genetic and non-shared environmental influences explained the variance in youth externalizing behaviors across all groups. For White youth, parental warmth, parental monitoring, and familism support moderated additive genetic (A), shared-environmental (C), and non-shared environmental (E) influences on externalizing behaviors, and familism obligations moderated C and E influences. Results from exploratory moderated heritability analyses conducted for the Black/African American and Hispanic samples are discussed. Altogether, these findings highlight the multiple avenues through which the family context can impact the development of youth externalizing behaviors, and reinforce the need to examine how these relations differ across racial/ethnic groups.

A Meta-Analysis of Experimental Examinations of Racism in U.S. Pre-K-12th Grade Educational Contexts

Description
Racism primarily has been examined in United States (U.S.) educational contexts via survey and qualitative investigations, which reveal Black, Indigenous, and People of Colors’ (BIPOCs’) self-reported experiences of individual racism. Missing from this research is a focus on the perpetrators

Racism primarily has been examined in United States (U.S.) educational contexts via survey and qualitative investigations, which reveal Black, Indigenous, and People of Colors’ (BIPOCs’) self-reported experiences of individual racism. Missing from this research is a focus on the perpetrators of racism and the institutional nature of racism in U.S. education. Experimental examinations of racism in U.S. education are efficacious in identifying perpetrators of racism and offer objective evidence of racism, which can underscore the importance of qualitative and survey findings. However, experimental examinations of racism in educational contexts are infrequent, examine a wide array of perpetrators (e.g., peers, teachers, principals) and educational domains (grading, diagnoses, liking), and reveal mixed findings. Thus, I utilized meta-analytic techniques to explore the magnitude of the effect of racism in pre-K-12th grade contexts as demonstrated by experimental examinations. In addition, I explore moderation of the effect of racism by 1) the type of experimental technique, 2) the specific perpetrator, 3) the BIPOC target, 4) the region of the US, and 5) the design of treatment assignment. Using 71 effect sizes from 57 studies, I found evidence that racism is present in U.S. pre-K-12th grade education for BIPOC [Cohen’s d=0.15, 95% CI(0.05, 0.25)]. Heterogeneity existed in the overall effect, and moderators included the U.S. region, and the level of racism (e.g., individual versus institutional) explained the heterogeneity of the effects. The findings are discussed in terms of theoretical and methodological implications and future directions for research.

Novel Measures of Culture and Their Relation to Self-regulation in Middle Childhood: A Genetically Informed Twin Study

It has been theorized that cultural variation within the family shapes children’s self-regulatory competence, yet there is a dearth of research examining the relation between culture and self-regulation. Family orientation refers to the emphasis on providing support, respect, and obligation to the family system, and is important for children’s functioning, yet existing literature on related constructs relies on parent-reported measures. Additionally, quantitative genetic research has neglected the role of culture in the genetic and environmental contributions on children’s self-regulation. There were three main aims of this study: 1) to propose novel coding schemes and factor analytic approaches to capture family orientation, 2) to examine the relation between family orientation and self-regulation in middle childhood, and 3) to examine whether family orientation moderates the genetic and environmental influences on self-regulation in middle childhood. The sample was drawn from the Arizona Twin Project (N=710) where children (49.1% female, 55.6% White, 28.3% Hispanic/Latino) were assessed at approximately eight years of age (Mage = 8.38 years, SD = 0.66). Family orientation values were indexed by parent-reported familism, whereas family orientation behaviors comprised coded measures of children’s family orientation and experimenter ratings of caregiver and child behavior. Outcome measures of self-regulation included the Continuous Performance Task, Flanker Task, Digit Span Backward, and parent- and teacher-reported effortful control (Temperament in Middle Childhood Questionnaire). Higher family orientation behaviors predicted positively predicted children’s self-regulation, with the exception of Digit Span Backward performance, and associations were not moderated by child sex, family SES, or race/ethnicity. Twin models revealed that differences in family orientation behaviors could be attributed to genetic, shared, and nonshared environmental influences, and additive genetic and nonshared environmental influences explained the variation across measures of self-regulation. Finally, there was no evidence that family orientation values nor behaviors moderated the genetic or environmental influences on children’s self-regulation. This study highlights the complex nature of cultural variation within the family and its importance for children’s self-regulatory abilities.

The thesis project merges interdisciplinary research to develop a self-directed creative intervention for immigrant youth, allowing them to make sense of their social and cultural identities. It takes research on self-awareness, multicultural identification, perceived belonging, and bibliotherapy to create a guided journal titled "Unearth," filled with art and writing prompts that are age-appropriate for adolescents and that serve as avenues for self-exploration. The project ultimately engages a focus group discussion to understand the usability and accessibility of the intervention.
