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
This quasi-experimental, mixed-methods action research study explored perceived levels of resilience for academic and peer-related settings among sixth-grade females in an independent middle school. A 5-week after-school intervention aimed to provide treatment participants with the opportunity to foster resilience by utilizing grit, growth mindset, and mindfulness practices. Pre and postsurveys (n = 26) completed by treatment and control groups showed that sixth-grade females experience a number of different academic and peer-related stressors with some of the most common stressors including bad grades in a class and feeling left out by peers. Survey findings also showed that treatment and control participants rated themselves highest in areas of flexibility for both peer and academic settings. Treatment and control participants rated themselves lowest on questions related to self-efficacy and emotional regulation in both peer and academic settings. While there were not statistically significant increases in perceived levels of resilience found for the treatment group pre- and post-intervention, interviews with treatment participants (n = 16) and workshop artifacts indicated that students found the exercises taught in the intervention helpful to navigate academic and peer related stressors they encounter. Implications for practice and research are discussed.

Description
Infectious disease presents a serious threat to our fitness. The biological immune system provides several mechanisms for dealing with this threat. So too does another system: the behavioral immune system. This second system is proposed to consist of a set of evolved cognitive, affective, and behavioral strategies for reducing the likelihood of infection, including xenophobia, traditionalism, and food neophobia. In the present work, I investigate how another suite of fairly novel culturally-learned disease avoidance strategies, namely hygiene behaviors and knowledge of germ theory, are related to the behavioral immune system. Across two studies, I find that individuals who engage in more hygiene behaviors show less evidence of reliance on several elements of the behavioral immune system (i.e., xenophobia, traditionalism, food neophobia). Similarly, individuals who know more about germ theory show less engagement in behavioral immune system components. These findings suggest that effective cultural strategies for avoiding infectious disease may supplant older, evolved psychological strategies with the same purpose.

Description
The COVID-19 pandemic has affected many aspects of daily life due to social distancing guidelines, including physical exercise. Prior research indicates that physical activity is a potent resilience factor against stress’ impact on mental health. Further, research suggests that social integration and participation positively contributes to mental well-being. Yet, one aspect of physical activity that may be particularly impacted by social distancing guidelines is the social context. It is unclear if those who participated in social physical activity prior to the COVID pandemic are more impacted by the restrictions placed on these behaviors. In a sample of 519 adults in the United States, the current longitudinal study examined whether participation in social physical activity, compared to individual physical activity, moderates the influence of pandemic stress on mental health and whether there are gender differences between men and women in these associations. Study results indicated physical activity did benefit mental health during the COVID pandemic. However, greater social physical activity did not buffer against the negative impact of stress. Future research should examine other variables potentially influencing these relationships, and examine them under non-pandemic conditions.

Description
Although adverse events cannot always be prevented, the negative outcomes on development can potentially be modified by considering methods of fostering positive emotional and behavioral responses. The study examined biopsychosocial health outcomes in the presence of uncontrollable adverse childhood events with the goal of identifying a potential intervention to increase resilience, health, and safe behaviors among at-risk children. It was hypothesized that adverse events can result in positive biopsychosocial outcomes in the presence of high scores on the Positive Emotion, Engagement, Relationships, Meaning, and Accomplishments (PERMA) model of well-being, self-efficacy, gratitude, and the ability to envision a positive future self. The study retrospectively examined adverse childhood events and present behavioral, emotional, and physical health outcomes. Participant (n = 685) data were analyzed using Hayes PROCESS (v3.5) to test all components of the moderation model. Results suggest that as adverse events increase, health adversity also increases. However, those with high intrapersonal strengths showed better health outcomes. Through understanding intrapersonal pathways in the presence of adverse events, the study can potentially identify mechanisms important for promoting resilient outcomes in childhood that could cascade into adulthood.

Description
Evaluators of eyewitness evidence (e.g., judges, jurors) often must determine whether an eyewitness’s identification of a police suspect is accurate or mistaken. It has recently been argued that a particular class of variables—suspect-bias variables—pose a unique threat to the reliability of eyewitness identification evidence. Unlike “general impairment” variables that generally impair eyewitness identification accuracy (e.g., poor viewing conditions, biased lineup instructions), suspect-bias variables produce a suspect-specific bias that increases the risk of confident misidentifications of innocent suspects. The goal of this research was to examine evaluators’ sensitivity to suspect-bias variables compared to general impairment variables, and to test whether sensitivity to suspect-bias differs as a function of whether the suspect-bias variable is under the control of the legal system (system suspect-bias) or outside of the legal system’s control (estimator suspect-bias). Participant-evaluators (N = 214) read eight crime vignettes paired with one of four different eyewitness variables (system suspect-bias, estimator suspect-bias, general impairment, or no-variable control) and rated the accuracy of each eyewitness. Evaluators also explained the reasoning for their accuracy rating, and their explanations were coded for mentions of procedural suggestion, eyewitness memory strength, memory contamination, and general eyewitness (un)reliability. Evaluators appear to be more sensitive to general impairment variables than to suspect-bias variables. This finding is alarming, as suspect-bias variables pose a greater threat to eyewitness reliability than general-impairment variables. Implications for the collection and evaluation of eyewitness evidence are discussed.

Description
Latinx sexual minority adults experience diverse types of discrimination, including heterosexism and ethnic/racial discrimination, which may contribute to worse physical health. Yet little research has examined how intersectional forms of discrimination, for example, discrimination within another marginalized community contribute to physical health. Greater experiences of discrimination can lead to greater psychological distress which may then exacerbate physical symptoms. It was hypothesized that the association between intersecting forms of discrimination and physical symptom severity would be mediated by psychological distress. Participants (N = 369) identified as Latinx/Hispanic/Latino and as a sexual or gender minority. Data were collected via a self-report web-based survey. Using structural equation modeling, this study tested two theory-informed structure equation models (SEM) proposing pathways between perceived general and within-group discrimination (i.e., Model 1 = racism and racism within LGBTQ+ community; Model 2 = heterosexism and heterosexism within ethnic/racial community), psychological distress (i.e., anxiety and depression), and physical symptom severity. Both structural models demonstrated good fit to the data. As hypothesized, heterosexist discrimination (β = .184, p = .007) and racist discrimination (β = .284, p = .001) significantly predicted higher physical symptom severity in their respective models. Depression symptoms significantly mediated the association between ethnic/racial discrimination and physical symptom severity (β = .189, p = .003). Similarly, greater frequency of heterosexism within one’s ethnic/racial community was indirectly related with worse physical symptoms severity via depression (β = .200, p = .002). No other indirect effects were significant. Findings from this study support that Latinx sexual minority adults may be at risk for discrimination from outside and within their own minority groups which has detrimental effects on health. Noteworthy, depressive symptoms appeared to mediate the effects of heterosexism in one’s ethnic/racial group on physical symptoms. These results highlight how overlapping forms of stigma have differential effects on health via psychological distress. These findings have important clinical and scientific implications in understanding how overlapping forms of discrimination affect health among Latinx sexual minority adults.

Description
Transgender populations display disproportionately poorer health outcomes compared to the general population. On average, these populations tend to experience decreased well-being in part through increased mental health concerns (e.g., anxiety, depression) and poorer physical and behavioral health status. Understanding the process by which these deleterious outcomes occur for this population is integral to developing interventions. This thesis aimed to examine whether experiences of gender dysphoria and body dissatisfaction influenced the association of felt pressure to conform to gender norms with mental health and quality of life outcomes. Specifically, I hypothesized that greater pressure to conform to gender norms would be directly related to worse mental health and quality of life outcomes, and that gender dysphoria and body dissatisfaction would indirectly mediate this relationship. Furthermore, I hypothesized that participants' gender identity would moderate this relationship, such that transgender individuals would show stronger associations on all pathways as compared to cisgender individuals. The sample consisted of 211 individuals – 109 being transgender and 102 being cisgender. Participants completed a 15-minute online survey including a consent form. Results indicated partial support of hypotheses – pressure to conform to gender norms directly predicted outcomes of compromised mental health (i.e., depression, anxiety, and stress), but did not predict well-being or quality of life. Furthermore, gender dysphoria (but not body dissatisfaction) mediated the relationship between felt pressure for gender conformity and compromised mental health outcomes for cisgender participants, but unexpectedly not for transgender participants. Post hoc analyses suggest that perceived discrimination mediated the relation between felt pressure and all mental health measures and quality of life measures for both transgender and cisgender participants.

Transgender and nonbinary (TNB) people experience elevated rates of post-traumatic stress disorder (PTSD) due to transphobic violence, discrimination, microaggressions, and minority stress. Oppression against TNB people could also contribute to complex post-traumatic stress disorder (c-PTSD) symptoms, which arises due to exposure to prolonged and repeated trauma from a state of subordination. Nonbinary people in particular experience unique chronic minority stressors (e.g., misgendering, interpersonal invalidation) because of the assumption that gender is inherently binary. These chronic minority stressors threaten nonbinary people’s psychological and interpersonal senses of safety. This study aims to examine how misgendering and invalidation can predict PTSD and c-PTSD symptoms among nonbinary people and whether this association is moderated by pride and community connectedness. Cross-sectional data from 611 nonbinary people were analyzed using hierarchical linear regressions. Misgendering and invalidation were found to be significant predictors of PTSD and c-PTSD symptoms. However, pride and community connectedness were not significant moderators of these associations. Findings from this study contribute to the conceptualizations of traumatic stress among nonbinary people and provide considerations for more affirming trauma-informed care. Future research should explore how additional resilience factors may promote resilience and healing for nonbinary people coping with trauma.

How do political elites perceive regional intergovernmental organizations that seek to promote democracy? When do political elites view regional intergovernmental institutions promoting democracy as legitimate? Many informal and formal types of regional intergovernmental institutions have sought to spread democracy. However, previous research on the nexus of regional intergovernmental institutions and democracy has focused primarily on the latter. Furthermore, these studies claim that membership in these formal international institutions (a.k.a. international organizations) increases the likelihood of the democratic survival of a newly democratic regime. Membership in these organizations provides a seal of approval that the newly democratic country intends to remain democratic. This kind of external validation should dissuade spoilers from undermining the transition and encourage ordinary people to support the transitional regime. This argument assumes that the domestic audience trusts this organization and believes it plays a vital role in society. Whether elites have confidence that the regional organization can positively impact democratic consolidation and how they perceive different types of regional organizations promoting democracy are empirical questions. This project seeks to answer these questions through a small sample and non-population-based elite survey experiment in Malaysia, Indonesia, and the Philippines. I also run a laboratory survey experiment with a larger sample of university students, giving me the opportunity for statistical power. The results suggest that political elites are skeptical of regional intergovernmental bodies promoting democracy. Meanwhile, non-elites consider regional institutions promoting democracy illegitimate when they are informal, i.e., no written shared expectations, rules, and permanent secretariat. When regional interstate cooperation on democracy operates under a formal procedure or codified in an international treaty and supported by a permanent secretariat, non-elites tend to consider them more legitimate.
