Description
The transition to college is a time of increased opportunity and stress that spans across multiple domains (e.g., social life, academic workload, finances). Adolescents who encounter significant stress during the transition to college may be vulnerable to adverse outcomes, due to a “wear and tear” of physiological systems, including the hypothalamic-pituitary-adrenal (HPA) axis. Latino students may be particularly at-risk for heightened stress exposure, as minority youth often experience both minority-specific stressors and general life stress. Despite this, the majority of research on Latino students is limited to the examination of singular forms of stress, and little is known regarding the cumulative impact of multiple forms of stress on Latino students’ HPA axis functioning. The present study employed a “multi-risk model approach” to examine the additive, common, and cumulative effects of multiple types of stress (general, academic, social, financial, bicultural, discrimination) on HPA axis functioning in Latino college students (N = 209; 64.4% female; Mage = 18.95). Results from three-level growth curve models indicated that, in the additive model, no stressors were associated with the CAR, but general stress was associated with a flatter diurnal cortisol slope (DCS) and bicultural stress was linked with a steeper DCS. In the common model, the college stress latent factor was related to a reduced cortisol awakening response (CAR), but not the DCS. In the cumulative model, cumulative risk was linked with a lower CAR, but not the DCS. These findings highlight the physiological correlates of various stressors experienced by Latino college students.

Description
Background: Premature infants may be at risk for lower effortful control, and subsequent lower academic achievement, peer competence, and emotional and physical wellness throughout the lifespan. However, because prematurity is related to obstetrical and neonatal complications, it is unclear what may drive the effect. Effortful control also has a strong heritable component; therefore, environmental factors during pregnancy and the neonatal period may interact with genetic factors to predict effortful control development. In this study, I aimed to dissect the influences of genetics, prematurity, and neonatal and obstetrical complications on the development of effortful control from 12 months to 10 years using a twin cohort. Methods: This study used data from the Arizona Twin Project, an ongoing longitudinal study of approximately 350 pairs of twins. Twins were primarily Hispanic/Latinx (23.8%-27.1%) and non-Hispanic/Latinx White (53.2%-57.8%), and families ranged in socioeconomic status with around one-third falling below or near the poverty line. Of the twins, 62.6% were born prematurely. Effortful control was assessed via parent report at six waves. Results: There was not a significant relationship between gestational age and effortful control regardless of whether obstetrical and neonatal complications were controlled for. Biometric twin modeling revealed that the attentional focusing subdomain of effortful control was highly heritable. Gestational age did not moderate genetic and environmental estimates. Conclusions: The findings help inform the risk assessment of prematurity and provide evidence for differing etiology of each subdomain of effortful control and the strong role of genetics in effortful control development.

Description
Latinxs are one of the largest ethnic-racial minoritized groups in the U.S., with children and youth serving as the driving force of the population’s growth. Latinx children and youth living in the U.S. navigate their development within sociocultural contexts that present unique stressors (e.g., discrimination) and assets (e.g., biculturalism) that shape their development. Thus, when studying Latinx youth and families, it is critical to consider important individual, developmental, and contextual factors that enhance Latinx youth development. This includes studying culture-specific family processes (e.g., familism) as well as more universal general parent-child processes that are developmentally salient (e.g., parent-child conflict regarding everyday issues). Therefore, my two-study dissertation focuses on the integration of cultural and developmentally relevant factors in studying parent-child relationships among Latinx families. In Study 1, I use longitudinal data from 246 Mexican-origin families to examine developmental trajectories of parent-child conflict regarding everyday issues across 12 to 22 years of age. In charting parent-youth conflict trajectories, I examine how youth and parent familism values may serve as important cultural factors that are associated with variation in parent-youth conflict. In Study 2, I use a person-centered approach to examine constellations of parental warmth, parent-child conflict, and parental ethnic socialization among Latinx families with children in middle childhood and explore how different patterns of parent-child relationships emerge and how these patterns relate to child adjustment (i.e., academic competence, peer competence, and depressive symptoms). Guided by a family systems theory, both studies consider important nuance in parent-child dyads by examining gender dynamics in mother-child and father-child relationships. Together, the studies make an important contribution to the understanding of culturally and developmentally salient processes of parent-child relationships in Latinx families and provide research and practice implications for enhancing the lives of Latinx youth and families.

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 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.

Description
Objective: This study examined time trends in associations of cannabis- and alcohol-related hospital visits with psychosis-related hospital visits in Arizona from 2016 to 2022.
Methods: Data were emergency department and inpatient hospital visits from all hospitals licensed and regulated by the Arizona Department of Health Services from January 2016 to December 2022 (n=21,921,214 visits). For each visit, data included patient demographics and International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes in up to 25 diagnostic fields. Exposures were cannabis and alcohol-related diagnoses (use, abuse, dependence), and the outcome was psychosis diagnoses.
Results: In any given year from 2016 to 2022, emergency department and inpatient hospital visits involving a cannabis-related diagnosis were 6-7 times more likely also to receive a psychosis diagnosis when compared with visits that did not include a cannabis-related diagnosis. By comparison, emergency department and inpatient hospital visits involving an alcohol-related diagnosis were only three times more likely also to receive a psychosis diagnosis.
