This dissertation used an evolutionary approach to examine the antecedents and outcomes to early pubertal development in girls in four major ethnic groups (i.e., European American, African American, Hispanic American, and Asian American). In the first study, logistic regressions were conducted to investigate the links between socioeconomic status (SES), parenting behaviors, and father absence to pubertal development across and within ethnic groups. SES and father absence predicted earlier pubertal development among European, African, and Hispanic Americans but not for Asian Americans. In the second study, growth curves were estimated for sexual outcomes across ethnic groups. Early developing European and African American girls had higher levels of sexual risk and pregnancy into adulthood. Puberty did not predict outcomes for Hispanic and Asian American girls. Overall, the findings from both studies revealed the importance of investigating childhood environmental contexts, puberty, and sexual health outcomes using an evolutionary perspective.

Early Childhood Education (ECE) classroom quality has been gaining increased attention from researchers and policy makers, as the link between high quality early learning experiences and future success has become clear. The impact of ECE may be particularly important for low-income, ethnic minority youth, who may need additional support to reach the academic level of their higher-income, Caucasian peers. However, the definition of ECE quality does not currently include indicators of classroom practices and center-wide policies that intentionally address issues of culture, race, and ethnicity, topics that may be particularly relevant for the most academically at-risk children. Anti-bias education (ABE) provides a strong theoretical and practical framework for understanding how to incorporate such themes into classroom practice and policy, as well as how to teach students to actively counteract bias and discrimination. However, there is currently no mechanism for researchers to utilize this framework, because there is no measure that can reliably evaluate the level of quality of ABE practices. Therefore, the present study sought to incorporate anti-bias education principles into the conceptualization of classroom quality through measurement development. The measure was developed based on the integration of the original ABE theory with interviews and observations in five ECE programs, which were nominated for their intentional practices regarding issues of culture, race, and ethnicity in the classroom. The five centers ranged in the ethnic composition and average income of their population. The resulting measure contains five domains, with a number of items within each domain. Two of the domains (Toys & Materials, Visual/Aesthetic Environment) contain observational rubrics for assessment, whereas the other three (Organizational Climate, Activities, Interactions) include self-report scales in addition to the rubrics. Future research is needed to pilot the measure and establish validity and reliability across contexts and observation times.

It is widely recognized that peer-directed aggression and victimization are pervasive social problems that impact school-aged children and adolescents. This study investigated the developmental course of aggression and victimization, and more specifically, addressed three primary aims. First, distinct subgroups of children were identified based on similarities and differences in their physical, verbal and relational aggression and victimization. Second, developmental stability (and instability) were assessed by examining the extent to which individuals remain (or change) subgroups throughout childhood and adolescence. Third, group classifications and transitions over time were assessed as a function of children’s individual characteristics and their relational and contextual experiences.

The sample for this longitudinal study consisted of 482 children (50% females) who were followed over time from grades 1 to 11. Multiple-informant data on children’s physical, verbal and relational aggression and victimization (peer-reports), individual characteristics including emotion dysregulation, withdrawn behaviors (teacher-reports), and hostile and self-blaming attributions (self-reports), and their relational and contextual experiences including peer rejection, friendships, social hierarchy and classroom aggression (peer-reports) were assessed in grades 1, 5, 8, and 11. Data analyses primarily consisted of a series of person-centered methods including latent profile and latent transition analyses.

Most of the identified subgroups (e.g., aggressors, victims and aggressive-victims) were distinguishable by their frequencies (i.e., levels) of aggression and victimization, rather than forms (physical, verbal and relational), with the exception of one group that appeared to be more form-specific (i.e., relational aggressive-victims). Among children in each group there was a modest degree of intra-individual stability, and findings elucidated how some groups appeared to be more stable than others as well as developmental differences. Although group stability was fairly common across all groups, and over time, patterns of instability also emerged.

The combination of trends reflecting both stability and instability support the perspective that the development of aggression in childhood and adolescence is characterized by heterogeneity. In contrast to perspectives that highlight the individual stability of aggression (e.g., that it is a stable behavioral style or individual disposition), findings elucidate the individual, relational and contextual mechanisms by which developmental stability and instability were more pronounced.
