Description
This study examined whether early adversity at 30-months moderated the heritability of common and individual components of EF at 8 years. It was hypothesized that early adversity would not moderate the common EF factor, but instead moderate individual EF components. The sample included 208 twin pairs from the Arizona Twin Project. Early Adversity, assessed at 30 months of age, included Parenting Daily Hassles, low perceived MOS social support, punitive punishment (Parental Responses to Child Misbehavior), home chaos (Confusion, Hubbub, and Order Scale), CES-D maternal depression, and low maternal emotional availability. EF at 8 years included the Eriksen Flanker Task, Continuous Performance Task, Digit Span Forward and Backward, and parent-reported Attentional Focusing and Inhibitory Control (Temperament in Middle Childhood Questionnaire). For both early adversity and EF, the first principal components were extracted as composites. A confirmatory factor analysis was also conducted to index common EF. Genetic analyses were tested on the common EF composites as well as each individual task using umx. Univariate models revealed genetic influences on all individual measures and common EF, with broad sense heritability from .22 (Digit Span Backwards) to .61 (parent-reported inhibitory control). Shared environmental influences were found for the Flanker Task (.13) and parent-reported inhibitory control (.24), and E was moderate to high (.40-.73) for all measures except parent-report inhibitory control (.15) and attentional focusing (.31). Moderation of heritability was not observed in for Digit Span Forward, Digit Span Backward, and Attentional Focusing. However, the nonshared environment was moderated for Common EF, and the Flanker Task, and additive genes and the nonshared environment were moderated for the Continuous Performance Task and Inhibitory Control. Generally, total variance decreased as early adversity increased, suggesting that homes with low levels of adversity may allow children to interact with more proximal processes that can promote EF development.

Description
Rapidly growing research on mothers’ perinatal depression, has demonstrated significant links among mothers’ depressive symptoms during pregnancy and the first year postpartum, their parenting, and multiple aspects of children’s development. This prospective longitudinal study contributes to research on mothers’ perinatal depression by examining the mechanisms by which maternal perinatal depression is associated with children’s adjustment early in development in a sample of 204 Mexican-origin adolescent mothers (Mage at Wave 1 = 16.80, SD = 1.0) and their children (58% boys). I expected that adolescent mothers’ negative parenting behaviors would mediate the associations between mothers’ perinatal depressive symptoms and three child outcomes: internalizing symptoms, externalizing behaviors, and cognitive ability. I further hypothesized that mothers’ perceived social support from their family would modify the extent to which mothers’ perinatal depressive symptoms negatively impact their parenting behaviors and their children’s developmental outcomes. Mothers reported on their own depressive symptoms, their perceived social support from their family and their children’s internalizing and externalizing problems; negative parenting was assessed using observational methods; and children’s cognitive ability was assessed using standardized developmental assessments. In this sample, adolescent mothers’ negative parenting behaviors did not significantly mediate the relations between mothers’ perinatal depression and children’s developmental outcomes. Further, perceived social support did not significantly buffer the effects of mothers’ perinatal depression on mothers’ negative parenting or children’s developmental outcomes. However, in line with hypotheses, results indicated that mothers’ prenatal depression had a wider impact on children’s adjustment outcomes than mothers’ postpartum depression, which appeared more specific to children’s internalizing problems. Discussion focuses on implications for intervention addressing adolescent mothers’ perinatal depression, as well as the need to continue to explore protective factors that have the potential to disrupt the negative intergenerational transmission of risks.

Description
Effortful Control (EC) is a person's ability to self-regulate when presented with an environmental stimulus (Rothbart, et al., 2003). It has been well-established that high levels of EC are associated with multiple positive social and academic outcomes in adolescence (Spinrad et al., 2009). Research suggests that parents have a strong impact on numerous child outcomes, such as EC, through both genetic and environmental pathways. Past research has also examined how parents diagnosed with psychopathology contribute to maladaptive outcomes in their children, including poor regulation, through both genetic and environmental processes (Ellis, et al., 1997). However, less is known about the longitudinal effects of parent dysfunction on the child's environment and regulatory abilities and potential mediators of those effects. The current study tested the hypotheses that parent Alcohol Use Disorder (AUD) would specifically predict early adversity, biological mother conscientiousness, and child EC longitudinally and that early adversity and biological mother conscientiousness would predict child EC. Participants were from a longitudinal study of familial alcoholism (N = 195). Regression analyses indicated that parent AUD was not specifically associated with child EC or with biological mother conscientiousness. However, parent AUD was related to higher levels of early adversity. Additionally, biological mother conscientiousness was associated with higher levels of child EC and early adversity was associated with lower levels of child EC when controlling for earlier EC. Given these findings, future research should test mediation models in which parent AUD predicts child EC indirectly through early adversity.

Description
I investigated if race/ethnicity was associated with self- and peer-reported victimization and aggression in a sample of 5th through 8th graders (N = 383, 51% males) from two schools in which Hispanic/Latino students were the ethnic-racial majority. Self-reported victimization did not differ between races. In contrast, White students often had higher peer-reported victimization relative to Hispanic and Multi-racial students. Few significant associations were found for aggression. There was some, albeit inconsistent, support for the idea that power imbalance based on race/ethnicity is shifted by numbers. In the future, researchers should conduct studies aimed verifying this notion and that are tailored toward answering questions of mechanism.

Abstract: This purpose of this paper is to analyze and evaluate the effectiveness of a student-driven sexual assault intervention at Arizona State University. The first aim is to develop a theoretical framework of the organization and its relation to the Integrated Behavioral Health model. The second aim analyze change in attitudes and beliefs about sexual violence and bystander behaviors as well as barriers and facilitators of change including perceived control and self-efficacy for students involved in the Respect Movement. The final aim is to analyze how this change transmits through the broader social network of students involved in the Respect Movement.

Description
Adolescent mental health problems are predicative of future problems such as depression, anxiety, ADHD, compulsive disorder, and substance use. Previous studies show that in emerging adulthood, the high prevalence and associated burdens of psychopathology increase vulnerability to disorders. These diagnoses are less common but are more severe and chronic (Tanner et al., 2009). The causes of these disorders are still being explored with recent studies showing that these mental health problems are genetically influenced. This makes understanding which gene that corresponds to what biological system is important in determining mental health. From recent studies, genes that code for calcium channels are good candidates for mental health problems. These voltage-gated channels are important mediators for physiological functions in the central nervous system and their activation provides unique responses within the brain. In a previous study, it supports the association of polymorphisms in calcium and potassium channels with the genetic risk for bipolar disorders and other mental illness (Imbrici et al., 2013). The purpose of the study was to examine if calcium channel genes influence childhood psychiatric symptoms. The first goal of this study was to form a polygenic risk score representing genetic influence on calcium channels. The second goal was to use this risk score in genetic association analyses to understand genetic risk for childhood psychopathology. Overall, the study did accomplish the goal as a polygenic risk score was created and was used to examine genetic association with child psychopathology. Based on the results, the polygenic risk score was not correlated with either parent or child- reported symptoms; however, results did show that disorders were related to each other and differed by race.

Description
Both theoretical and empirical research has recognized the importance of contextual factors for Mexican-origin youths' educational outcomes. The roles of parents, teachers, and peers have been predictive of Mexican-origin youths' academic achievement, educational expectations, and decision to enroll in postsecondary education. However, few studies have examined the interdependence among sociocultural context characteristics in predicting Mexican-origin youths' educational outcomes. In this dissertation, two studies address this limitation by using a person-centered analytical approach. The first study identified profiles of Mexican-origin youth using culturally relevant family characteristics. The second study identified profiles of Mexican-origin youth using culturally relevant school characteristics. The links between profiles and youths' academic achievement, educational expectations, and postsecondary enrollment were examined in both studies. Overall, this dissertation contributes to the growing body of literature that aims to understand risk and protective processes related to Mexican-origin youths' academic achievement, educational expectations, and postsecondary enrollment.

Description
School-based mental health services aim to foster positive academic and behavioral outcomes in students, however families often are not directly involved in implementing these practices. Family engagement in schools should be an essential focal point in school-based mental health services, as the partnership between families and schools has been shown to lead to positive student outcomes. This study used an evaluation tool known as the FAMSET to examine the PFS CARE intervention, a trauma-informed and culturally responsive intervention measuring family engagement in schools, which operates from an MTSS-framework. Specifically focusing on trauma-informed and culturally responsive practices, administrators and staff members were asked a series of thirteen questions regarding the construct. This study aims to examine the construct of trauma-informed and culturally responsive practices, to analyze administrator and staff differences, and to create a consolidated scale. Results showed that overall, the scales were efficient in capturing the construct of trauma-informed and culturally responsive practices, and the scales should be analyzed separately for administrators and staff members; additionally, several questions should be omitted or reworded in the administrator survey in future administrations. Family engagement in schools is an understudied topic, and one with promising future implementations – this study is one of the first to evaluate the FAMSET tool. In future studies, this preliminary data can be used to create a validated scale, and it is recommended that future samples are larger and expand to other faculty positions as well.
