Description
Accumulating evidence implicates exposure to adverse childhood experiences in the development of hypocortisolism in the long-term, and researchers are increasingly examining individual-level mechanisms that may underlie, exacerbate or attenuate this relation among at-risk populations. The current study takes a developmentally and theoretically informed approach to examining episodic childhood stressors, inherent and voluntary self-regulation, and physiological reactivity among a longitudinal sample of youth who experienced parental divorce. Participants were drawn from a larger randomized controlled trial of a preventive intervention for children of divorce between the ages of 9 and 12. The current sample included 159 young adults (mean age = 25.5 years; 53% male; 94% Caucasian) who participated in six waves of data collection, including a 15-year follow-up study. Participants reported on exposure to negative life events (four times over a 9-month period) during childhood, and mothers rated child temperament. Six years later, youth reported on the use of active and avoidant coping strategies, and 15 years later, they participated in a standardized psychosocial stress task and provided salivary cortisol samples prior to and following the task. Path analyses within a structural equation framework revealed that a multiple mediation model best fit the data. It was found that children with better mother-rated self-regulation (i.e. low impulsivity, low negative emotionality, and high attentional focus) exhibited lower total cortisol output 15 years later. In addition, greater self-regulation in childhood predicted greater use of active coping in adolescence, whereas a greater number of negative life events predicted increased use of avoidant coping in adolescence. Finally, a greater number of negative events in childhood predicted marginally lower total cortisol output, and higher levels of active coping in adolescence were associated with greater total cortisol output in young adulthood. Findings suggest that children of divorce who exhibit better self-regulation evidence lower cortisol output during a standardized psychosocial stress task relative to those who have higher impulsivity, lower attentional focus, and/or higher negative emotionality. The conceptual significance of the current findings, including the lack of evidence for hypothesized relations, methodological issues that arose, and issues in need of future research are discussed.

Description
Type 1 Diabetes Mellitus (T1DM) is a chronic disease that requires maintaining tight metabolic control through complex behavioral and pharmaceutical regimens. Subtle cognitive impairments and stress response dysregulation may partially account for problems negotiating life changes and maintaining treatment adherence among emerging adults. The current study examined whether young adults with T1DM physiologically respond to psychological stress in a dysregulated manner compared to non-diabetic peers, and if such individuals also demonstrated greater cognitive declines following psychological stress. Participants included 23 young adults with T1DM and 52 non-diabetic controls yoked to T1DM participants based on age, gender, ethnicity, participant education, and maternal education. Participants completed a laboratory-based social stressor, pre- and post-stressor neurocognitive testing, provided fingerstick blood spots (for glucose levels) and salivary samples (for cortisol levels) at five points across the protocol, and completed psychosocial questionnaires. Related measures ANOVAs were conducted to assess differences between T1DM participants and the average of yoked controls on cortisol and cognitive outcomes. Results demonstrated that differences in cortisol reactivity were dependent on T1DM participants' use of insulin pump therapy (IPT). T1DM participants not using IPT demonstrated elevated cortisol reactivity compared to matched controls. There was no difference in cortisol reactivity between the T1DM participants on IPT and matched controls. On the Stroop task, performance patterns did not differ between participants with T1DM not on IPT and matched controls. The performance of participants with T1DM on IPT slightly improved following the stressor and matched controls slightly worsened. On the Trail Making Test, the performance of participants with T1DM was not different following the stressor whereas participants without T1DM demonstrated a decline following the stressor. Participants with and without T1DM did not differ in patterns of performance on the Rey Verbal Learning Task, Sustained Attention Allocation Task, Controlled Oral Word Association Task, or overall cortisol output across participation. The results of this study are suggestive of an exaggerated cortisol response to psychological stress in T1DM and indicate potential direct and indirect protective influences of IPT.

Description
The beginning of college is a period in which increased alcohol use often coincides with greater involvement in romantic relationships. Existing literature yields inconsistent findings regarding the influence of different relationship statuses on drinking behavior, perhaps because these studies have not accounted for recent changes in the way college students engage in dating/sexual relationships. In the current college environment, many students who define themselves as non-daters are nonetheless sexually active, a phenomenon referred to as the 'hook up' culture. The present study sought to address this issue by examining the effects of both relationship status and sexual activity on heavy episodic drinking (HED) among 1,467 college students over the course of their first three semesters. Results indicated that the effects of relationship status depended on whether or not an individual was sexually active. Non-dating but sexually active students reported rates of heavy drinking comparable to students who defined themselves as casual daters, but non-dating students who were not sexually active reported drinking behavior similar to those involved in committed relationships. Further, transitions between low and high risk relationship/sexual activity statuses were associated with corresponding changes in HED. Transitioning into a high risk status was associated with greater levels of heavy episodic drinking, whereas transitioning into a low risk status was associated with decreases in this behavior. Together, results indicate that engaging in nonexclusive dating or sexual relationships may play an important role in the development of problematic patterns of alcohol use during the early college years. These findings have potentially important implications both for future research and for prevention and intervention efforts targeting high risk college drinkers.

Description
Research has suggested that lonely people demonstrate distinct differences from nonlonely people in their behaviors, mood, and interpersonal experiences. Lonely people who are also enduring a chronic pain condition may be at an especially high risk for negative outcomes because of simultaneous issues such as stigma, mood disturbances, and pain-related disability. The current study examined chronic and transitory loneliness in a sample of 123 chronic pain patients. Participants completed daily diaries assessing the occurrence of positive and negative interpersonal events, appraisals of interpersonal events, pain, and mood. Multilevel modeling was used to examine effects of being a lonely person as well as having a lonely episode on daily life. Results indicated that both chronic and transitory loneliness were associated with more frequent negative and less frequent positive interpersonal events, higher levels of pain, more negative and less positive affect, and more stress and less enjoyment from social interactions. Loneliness did not affect reactivity to negative interpersonal events, but did influence responsivity to positive interpersonal events such that lonely people had greater boosts in enjoyment when experiencing more positive interpersonal events than usual. These findings suggest that both lonely people and individuals experiencing a lonely episode experience more negative consequences in their daily lives than nonlonely people. However, they can benefit from engaging in more frequent positive interpersonal events, which can help to inform future clinical interventions for lonely, chronic pain patients.

Description
Childhood trauma has been linked to an increased risk of chronic pain in adulthood. One potential mechanism is via childhood trauma's impact on the hypothalamic-pituitary-adrenal axis (HPA) response to stress, reflected in changes in salivary cortisol levels (Nicolson et al., 2010). This study sought to determine the relations between childhood trauma, increases in cortisol levels following induced pain, and pain perceptions in adults with fibromyalgia, a chronic pain condition. It drew on data collected from participants enrolled in an investigation comparing the effectiveness of behavioral treatments for chronic pain. Before receiving treatment, participants attended a laboratory session during which they first rested, and then were exposed to heat stimuli to assess pain threshold and tolerance. Saliva samples were collected from each participant immediately following the rest, and twice during pain induction. Fibromyalgia participants with a history of childhood trauma were expected: 1) to report lower pain threshold and tolerance levels (i.e., have higher pain sensitivity), 2) to exhibit a higher resting cortisol level, and 3) to have greater increases in cortisol in response to acute pain induction than fibromyalgia participants without a history of childhood trauma. Findings showed that childhood trauma scores were: 1) related to lower pain tolerance (but not pain threshold), 2) unrelated to resting cortisol levels, and 3) unrelated to changes in cortisol in response to pain induction and pain tolerance, contrary to prediction. However, a subtype of childhood trauma, i.e., emotional maltreatment: 1) predicted lower pain tolerance, and 2) moderated the cortisol changes over time in response to pain induction during the laboratory session in the expected direction. That is, individuals who reported higher levels of childhood emotional maltreatment showed greater cortisol responses to the pain induction than individuals who reported lower levels of exposure to emotional maltreatment. Cortisol responses did not relate to pain perception. Thus, childhood emotional trauma predicted greater pain sensitivity and cortisol reactivity, but cortisol did not relate to pain perception. The findings suggest that early childhood trauma predicts cortisol reactivity and pain sensitivity, but that cortisol reactivity is not a mediator in the trauma-pain relation.

Description
Full Disclosure, an honors thesis painting exhibition presented by Bachelor of Fine Arts candidate, Natalie Saez, strives to visually document the mental progression of people undergoing the transformative process of art therapy. Although often times a term that brings people on edge under certain circumstances, full disclosure brings to light information that otherwise would not have been expressed. In this same way, the process of art making - specifically referring to art therapy - presents a form of full disclosure. Varying stylistic approaches ranging from naturalistic to more abstracted portraits within the exhibition serve as a way to depict the uninhibited expression that results from the creative process.

Description
Sibling interactions are natural contexts for learning about the appropriate expression of emotions. The emotionally charged nature of sibling interactions creates a convenient context to explore emotional reactivity and regulation. The purpose of this study was to examine the relations among parent-reported sibling relationship quality, observed sibling prosocial and antisocial behaviors displayed when playing a competitive marble game, and children's emotions coded from videotape. The sample consisted of 58 twin children who are currently participating in the longitudinal Arizona Twin Project. Parents completed the Sibling Relationship Questionnaire online at 5 and 8 years. Additionally, a competitive marble game interaction between the siblings took place in the home at 8 years and was videotaped for objective coding of prosocial, antisocial, and control behavior. Facial expressions were also coded from videotape using Emotient FACET software across the marble game interaction. Three mean composites of emotion were created, including positive and negative emotional facial expressions. Results showed that parent reported warmth did not predict the occurrence of positive emotions during the sibling interaction. However, siblings with high conflict showed less fear during the interaction. Parent reports of warmth predicted the extent to which siblings differed on emotion expression, however conflict did not. Parent ratings of conflict and warmth did not predict the extent to which the sibling dyad was emotionally intense. Findings regarding genetic and environmental effects were in line with previous reports of genetic influence on prosocial behavior and negative emotion, and expressions of joy being influenced by the environment. This study investigated noteworthy aspects of the sibling relationship that appear to promote children's adaptive development.

Description
Cultural beliefs and behaviors can serve as both risk and protective processes for Latino adolescents, with some recent empirical work suggesting the important protective role of bicultural values (e.g., endorsing high levels of both mainstream culture and culture of origin). We expanded on past research to explore whether bicultural values were associated with internalizing (depressive, anxiety, stress) symptoms and externalizing (alcohol use) symptoms among a sample of Latino adolescents preparing to begin college. We hypothesized biculturalism to protect against all negative outcomes. Our sample consisted of 209 college-bound Latino adolescents (65% female; 85.1% Mexican descent; 10.6% 1st generation, 62% 2nd generation) who were enrolled in university for the coming fall. All multivariate models included sex, ethnicity, parent education, and immigrant generation status as covariates. Correlations and multivariate analyses revealed that higher bicultural values were associated with lower depressive symptoms, lower anxiety symptoms, lower stress, and greater alcohol use. Gender was shown to moderate the relationship between biculturalism and alcohol use. Overall, findings suggested that greater bicultural values were associated with lower endorsement of internalizing symptoms for all participants, but higher endorsement of alcohol use over the last year for the highly bicultural females. Biculturalism may be particularly protective for Latino adolescents who are preparing to attend college given the need for them to transition into an environment with high acculturative demands. However, our results also highlight that these bicultural females may be at greater risk for alcohol use and related problems.

Description
Higher education institutions have increasingly sought to diversify the ethnic makeup of freshmen classes (Covarrubias, Herrmann, & Fryberg, 2016) and rates of Latinx college attendance have been rising (Hall, Nishina, & Lewis, 2017). However, despite comparable levels of earned-credits, Latinx students have lower rates of college completion (Contreras & Contreras, 2015). One potential explanation may be disproportionate increases in stress, and in particular, discrimination experiences reported by Latinx students during the transition from high school to college (Hunyh & Fuligni, 2012). As such, the aim of the current study was to examine whether everyday discrimination in high school and college were associated with changes in adolescent well-being and academic adjustment over the college transition in a sample of Latinx adolescents. Study participants were 209 Latinx adolescents (85.1% Mexican descent, 62.1% 2nd generation; 35.6% male; Mage= 17.59) who completed questionnaire assessments during the spring or summer before entering college (T1) and again during the first semester of college (T2; 88.5% retention). In both high school and college, participants completed a modified version of the Everyday Discrimination Scale (T1 α=.88, T2 α=.89; Williams et al., 1997). Dependent variables included internalizing symptoms in college (depressive symptoms {α = .95}, anxiety symptoms {α = .88}, stress symptoms {α = .94}; DASS; Lovibond & Lovibond, 1995), and institutional records of college GPA. Correlation and regression analyses were conducted in SPSS 23 to examine associations between discrimination experiences (high school and college) and college internalizing symptoms and GPA, controlling for high school levels. Other covariates included immigrant generation status, sex, parent education (as a proxy for socioeconomic status), and whether the participant attended the focal higher education institution. Zero order correlations (Table 1) revealed that greater reports of discrimination in high school and college were associated with higher depressive symptoms, higher anxiety symptoms, higher stress, but not GPA in college (Table 1; all ps <.05). In multivariate analyses and after adjusting for covariates similar patterns emerged (Table 2). Greater reports of discrimination in college were associated with higher depressive symptoms (β = .18, p < .05), anxiety symptoms (β = .19, p <.05) and stress (β = .18, p <.05), but not GPA (β = -.04, ns). Everyday experiences of discrimination in high school were not significantly associated with college outcomes. In summary, our findings suggest that discrimination experiences among Latinx students in college, but not high school, are associated with increases in internalizing symptoms, including depression, anxiety and stress. Interestingly, discrimination experiences in high school and college were not associated with academic achievement in the first semester of college. Such findings suggest that higher education institutions should focus on global indicators of well-being during the Latinx college transition and seek to implement programs to: a) reduce stress associated with engaging in diverse college environments and b) reduce discrimination experiences on college campuses. Future research is needed for replication of these results and should also seek to further explore the trajectories of internalizing symptoms beyond the first semester of college.

Description
Time spent alone is a topic that has been studied in great detail, particularly the manner in which it is spent and the effect it has during the adolescent stage of life. Similarly, stress levels in adolescents have always been a topic of interest because of the effects they could have on the individual later in adulthood. Oddly enough however, the two areas of study have never been looked at in relation to one another. This study will look at different types of alone time as possible stressors in a community sample (N=82) of adolescents transitioning to college. The data on time alone and stress levels was collected through diary reports over a period of 3 days. The analysis only yielded significant effects for females and only for specific categories. It was found that females experience the lowest amount of perceived stress when they are alone and want to be alone, they have more negative affect when their desired environment differs from their current situation, and more positive affect in both the alone incongruence and not alone congruence situations. These results indicate that only women experience stress and affect changes when they encounter different congruent and incongruent environments.
