Description
The purpose of this study was to determine if a relationship existed between acculturative stress and cardiovascular disease risk factors in Korean immigrants residing in the United States. This is a secondary analysis of existing data that was collected for a cross-sectional, descriptive study of 104 Korean American adults in a large Southwestern city in the U.S. Descriptive statistics, t-test, and analysis of variance were used to analyze data on demographics, acculturative stress, and biomarkers indicative of cardiovascular risk, such as body mass index (BMI), blood pressure (BP), and total cholesterol (TC). Most participants were women (66.3%), with a mean age of 53.59 (SD = 10.42), who were married (89.4%), educated at a college level or above (graduate) level (85.6%), employed full/part-time (64.4%), and had an annual household income of $50,000 or more (62.5%). The average length of residence in the U.S. was 22.04 years (SD = 11.89), Half of the study sample were overweight or obese (BMI > 23 kg/m2), 65.4% with high SBP (≥ 120 mmHg), 75.9% with high DBP (≥ 80 mmHg), and 75% with high TC (≥ 170 mg/dL). Acculturative stress was significantly associated with age, length of residence, and family annual income. Cardiovascular risk factors were significantly different by age, gender, marital status, education level, or employment status. However, the relationship between acculturative stress and cardiovascular risk indicators was not statistically significant. The study findings provide useful information about demographic characteristics, acculturative stress, and cardiovascular health of Korean immigrants in the United States. In order to prevent and manage cardiovascular health of the population, healthcare professionals should consider that cardiovascular risk factors may vary according to demographic characteristics in Korean immigrants.

Description
The relationship between stress and policing has long been established in literature. What is less clear, however, is what departments are doing to help officers deal with the stress that comes with the job. Looking at a small Southwestern police agency and using a modified version of Speilberger’s (1981) Police Stress Survey, the present study sought to examine stressors inherent to policing, as well as to identify departmental services that may be in place to help officers alleviate those stressors and whether or not police officers would choose to take part in the services that may be offered. The findings suggest that a shift in stress in policing is occurring with operational stressors being reported at higher levels than organizational stressors, contrary to previous research.

Description
Objective: The present study sought to 1) examine the measurement of emotional complexity (EC) by examining the associations among different indicators of EC (i.e., covariation between positive affect and negative affect; overall, negative, and positive granularity; overall, negative, and positive differentiation) derived from the same data set and identifying a latent factor structure; and 2) evaluate the predictive ability of EC on psychological distress, emotional well-being, and physical functioning while accounting for stressful contexts. The utility of assessing emotion diversity (ED) as another aspect of EC was also explored.
Methods: 191 middle-aged adults from a community-based study on resilience were asked to complete 30 daily diaries assessing positive and negative affect. At least 6 months later, participants completed a phone interview that assessed distress (i.e., depressive and anxiety symptoms), well-being (i.e., WHO-5 well-being, vitality, social functioning), physical functioning, and perceived stress.
Results: A three-factor solution with latent factors representing overall, negative, and positive EC was identified. Overall EC significantly predicted enhanced physical functioning, but was not associated with distress or well-being. Contrary to study hypotheses, positive and negative EC were not associated with future distress, well-being, or physical functioning, though a trend toward improved physical functioning was noted for positive EC. In contrast, positive and negative ED were both associated with less distress, and better well-being and physical functioning. Overall ED was unexpectedly related to worse outcomes (i.e., more distress, less well-being, decreased physical functioning). Stress did not moderate the relationship between emotional complexity and the outcome variables.
Conclusions: Different indicators of EC represent distinct aspects of emotional experience. Partial support of the hypotheses found. Physical functioning was the only outcome influenced by EC. The inclusion of stress did not change the results. The discrepancy between the findings and those in the literature may be related to reliability of EC indicators and absence of contextual factors. Further exploration of ED revealed a potentially important construct of emotional experience that is deserving of further inquiry.

Description
There is considerable recent interest in the dynamic nature of immune function in the context of an animal’s internal and external environment. An important focus within this field of ecoimmunology is on how availability of resources such as energy can alter immune function. Water is an additional resource that drives animal development, physiology, and behavior, yet the influence hydration has on immunity has received limited attention. In particular, hydration state may have the greatest potential to drive fluctuations in immunity and other physiological functions in species that live in water-limited environments where they may experience periods of dehydration. To shed light on the sensitivity of immune function to hydration state, I first tested the effect of hydration states (hydrated, dehydrated, and rehydrated) and digestive states on innate immunity in the Gila monster, a desert-dwelling lizard. Though dehydration is often thought to be stressful and, if experienced chronically, likely to decrease immune function, dehydration elicited an increase in immune response in this species, while digestive state had no effect. Next, I tested whether dehydration was indeed stressful, and tested a broader range of immune measures. My findings validated the enhanced innate immunity across additional measures and revealed that Gila monsters lacked a significant stress hormone response during dehydration (though results were suggestive). I next sought to test if life history (in terms of environmental stability) drives these differences in dehydration responses using a comparative approach. I compared four confamilial pairs of squamate species that varied in habitat type within each pair—four species that are adapted to xeric environments and four that are adapted to more mesic environments. No effect of life history was detected between groups, but hydration was a driver of some measures of innate immunity and of stress hormone concentrations in multiple species. Additionally, species that exhibited a stress response to dehydration did not have decreased innate immunity, suggesting these physiological responses may often be decoupled. My dissertation work provides new insight into the relationship between hydration, stress, and immunity, and it may inform future work exploring disease transmission or organismal responses to climate change.

Description
In wild birds, the stress response can inhibit the activity of the innate immune system, which serves as the first line of defense against pathogens. By elucidating the mechanisms which regulate the interaction between stress and innate immunity, researchers may be able to predict when birds experience increased susceptibility to infections and can target specific mediators to mitigate stress-induced suppression of innate immune activity. Such elucidation is especially important for urban birds, such as the House Sparrow (Passer domesticus), because these birds experience higher pathogen prevalence and transmission when compared to birds in rural regions. I investigated the role of corticosterone (CORT) in stress-induced suppression of two measures of innate immune activity (complement- and natural antibody-mediated activity) in male House Sparrows. Corticosterone, the primary avian glucocorticoid, is elevated during the stress response and high levels of this hormone induce effects through the activation of cytosolic and membrane-bound glucocorticoid receptors (GR). My results demonstrate that CORT is necessary and sufficient for stress-induced suppression of complement-mediated activity, and that this relationship is consistent between years. Corticosterone, however, does not inhibit complement-mediated activity through cytosolic GR, and additional research is needed to confirm the involvement of membrane-bound GR. The role of CORT in stress-induced inhibition of natural antibody-mediated activity, however, remains puzzling. Stress-induced elevation of CORT can suppress natural antibody-mediated activity through the activation of cytosolic GR, but the necessity of this mechanism varies inter-annually. In other words, both CORT-dependent and CORT-independent mechanisms may inhibit natural antibody-mediated activity during stress in certain years, but the causes of this inter-annual variation are not known. Previous studies have indicated that changes in the pathogen environment or food availability can alter regulation of innate immunity, but further research is needed to test these hypotheses. Overall, my dissertation demonstrates that stress inhibits innate immunity through several mechanisms, but environmental pressures may influence this inhibitory relationship.

Description
Having a child with special needs can be overwhelming, emotionally draining and extremely stressful for parents and their family members. Research identifies the support systems families need in order to have quality-of-life. The current study uses mixed methods to evaluate the degree to which parents and other primary caregivers in Arizona view the educational and health related services that their child with special needs and/or other health impairments received when they entered kindergarten. It evaluated the degree to which the caregivers themselves perceived the support/services that they received in order to access quality of life for themselves, their child with special needs and other family members. Finally, the research identified reoccurring themes to better understand the intricacies involved within these support systems/services that promoted or hindered positive family and child outcomes.

Description
Positive psychology focuses on the promotion of well-being (Seligman, & Csikszentmihalyi, 2000). Positive psychology interventions (PPIs) have been developed to help facilitate the development of skills needed to flourish and current research suggests that PPIs can help individuals improve their happiness, reduce stress, and become more resilient (Lyubomirsky, King, & Diener, 2005). National surveys highlight that students in higher education are in dire need of interventions aimed at helping them cope with the negative impact of stress (Douce & Keeling, 2014; Marks & Wade, 2015). Research among the graduate student population is scant even though they report high levels of stress and work even more hours than undergraduate students (Wyatt & Oswalt, 2013). PPIs implemented in the graduate student population focus heavily on psychologically-based programs, like psychology and social work, whose students may already be receiving assistance in self-care (Botta, Cadet, & Maramaldi, 2015; Burkhart, 2014; Nelson, Dell'Oliver, Koch, & Buckler, 2001). Thus, this current study is a randomized controlled trial testing an online PPI, adapted from Achor's work in the business industry (2012, 2014), compared with an online informative stress group and a wait list control group among graduate students from various disciplines at a large, public university in the Southwest. Participants were administered pre-, post-, and three-month follow-up tests to determine the impact of the interventions on their levels of perceived stress, happiness, and resilience. A multivariate analysis of covariance (MANCOVA) was used with covariates of age, gender, race, program of study, and graduate level of study (masters versus doctoral). The main findings of the study included: the students in the PPI group reported significantly higher resilience at the end of the three weeks than did the students in the informative stress or wait list control groups, even though measures of happiness or perceived stress were not impacted; and students from psychologically based programs received the most benefit from treatment, especially from the PPI intervention. All findings, implications, and suggestions for future directions are discussed.

Description
The demands and expectations of graduate school can be stressful for any student. Graduate students in a romantic relationship, in particular, contend with both individual and dyadic effects of graduate school stress, as stress has been found to be negatively associated with both individual and relational well-being. Asymmetrical graduate student couples, wherein one partner is in graduate school and the other is not, may be particularly vulnerable to relationship strain because of differences in their experience of graduate school. However, non-student partners can help the graduate student cope with stress through dyadic coping. This study sought to examine whether: a) there were associations between graduate school stress on individual (life satisfaction) and relational (relationship satisfaction) well-being, and b) whether these associations were moderated by positive and negative dyadic coping behaviors. Cross-sectional data from 62 asymmetrical graduate student couples were gathered using an online survey. Data were analyzed using Actor-Partner Interdependence Models (Kenny, Kashy, & Cook 2006). Separate models were conducted to examine overall associations between graduate stress and well-being, and additional analyses were conducted to examine potential moderation effects of perceptions of partner dyadic coping (actor effects) and partner self-reported dyadic coping (partner effects) on the overall associations between stress and life- and relationship satisfaction mentioned above. Results for the overall model suggested that graduate stress is associated with both individual- and relational well-being. Surprisingly, and against prior literature, positive dyadic coping did not buffer the negative association between graduate stress and well-being, and negative dyadic coping did not exacerbate the association. Implications of the findings for future research and for mental health counselors are discussed.

Description
Being married as an undergraduate student is uncommon, considering the average age people marry in the U.S. is 28-years-old. Given that the “traditional” undergraduate student is unmarried, being a married undergraduate student may be associated with the anticipation of stigma due to their marital status, which may be a stressful experience (hereafter-anticipated stigma stress) and have harmful effects on one’s well-being, particularly symptoms of anxiety. As such, it is important to identify ways in which romantic partners can help one another cope with this unique stressor by engaging in positive or negative dyadic coping (DC). Using cross-sectional data from 151 married undergraduate students, this project examined whether perceptions of partner’s positive and negative DC moderated the association between anticipated stigma stress and symptoms of anxiety. There was a significant main effect of anticipated stigma stress on anxiety, such that higher anticipated stigma stress was associated with greater symptoms of anxiety. Delegated DC moderated this association, such that when participants reported high levels of anticipated stigma stress, those who reported higher partner’s use of delegated DC also reported higher symptoms of anxiety as compared to those who reported low partner’s use of delegated DC. Implications for future research and mental health counselors are discussed.

Description
Cancer survivors engaged in either six-week Internet-delivered mindfulness training or a usual-care control and were compared on the following outcome battery: The Hospital Anxiety and Depression Scale, the Profile of Mood States, the Pittsburgh Sleep Quality Index, and the Fatigue Symptom Inventory. Assessments were conducted before and after treatment and intervention compliance was monitored. Mindfulness treatments were delivered at a time and on a computer of the participants’ choosing. Multivariate analysis indicated that mindfulness training produced significant benefits on all measures (p < .05). Online mindfulness instruction represents a widely-accessible, cost-effective intervention for reducing psychological distress and its behavioral manifestations in cancer survivors, especially those who are unable to participate in in-person training.
