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.

The main objective of this study was to use a genetically-informative design to examine the putative influences of maternal perceived prenatal stress, obstetrical complications, and gestational age on infant dysregulation, competence, and developmental maturity. Specifically, whether or not prenatal and obstetrical environmental conditions modified the heritability of infant outcomes was examined. A total of 291 mothers were interviewed when their twin infants were 12 months of age. Pregnancy and twin birth medical records were obtained to code obstetrical data. Utilizing behavioral genetic models, results indicated maternal perceived prenatal stress moderated genetic and environmental influences on developmental maturity whereas obstetrical complications moderated shared environmental influences on infant competence and nonshared environmental influences on developmental maturity. Gestational age moderated the heritability and nonshared environment of infant dysregulation, shared and nonshared environmental influences on competence, and nonshared environmental influences on developmental maturity. Taken together, prenatal and obstetric conditions were important nonlinear influences on infant outcomes. An evolutionary perspective may provide a framework for these findings, such that the prenatal environment programs the fetus to be adaptive to current environmental contexts. Specifically, prenatal stress governs gene expression through epigenetic processes. Findings highlight the utility of a genetically informative design for elucidating the role of prenatal and obstetric conditions in the etiology of infant developmental outcomes.

The transition from high school to college is associated with considerable life strain for adolescents, including higher reported levels of daily stress and negative affect (NA), and alterations in stress physiology have been linked to poor health. The purpose of this thesis was to use an ecological momentary assessment design to study associations between momentary experiences of negative affect and cortisol levels in a sample of adolescents transitioning to college. I also examined the potential moderating effects of two potential vulnerability or protective factors, alone status and perceived social support from friends. Adolescents provided salivary samples and completed paper-and-pencil diary reports of socioemotional experiences and alone status five times per day for three consecutive weekdays, as well as completed self-report questionnaires on perceived social support from friends. Within-person increases in momentary negative affect were associated with momentary cortisol reactivity. Alone status significantly moderated this association such that the association between momentary negative affect and momentary cortisol levels was only significant when individuals were with others and not when they were alone. Perceived social support from friends did not significantly moderate the within-person associations between negative affect and momentary cortisol levels. The findings add to our understanding of physiological correlates of socioemotional experiences, as well as contexts in which these associations may be exaggerated or attenuated. The findings inform our understanding of potential pathways by which physiological reactivity to socioemotional experiences may affect the health of adolescents as well as how prevention efforts could reduce potential poor health outcomes associated with heightened stress reactivity.

Dysregulated cortisol has been linked to a variety of adverse physical and psychological consequences. Stressors in the childhood family environment can influence cortisol activity throughout development. For example, research has shown that both infants and children of depressed mothers exhibit altered levels of cortisol compared to infants and children of non-depressed mothers. It is unclear, however, whether exposure to maternal depression in childhood and adolescence is related to cortisol activity at later stages of development. The current study examined the longitudinal relation between maternal depressive symptoms during late childhood (9-12 years old) and adolescence (15-19 years old) and cortisol activity in offspring in young adulthood (24- 28 years old) in a sample of 40 young adults and their mothers. Maternal depressive symptoms were prospectively assessed at four time points across the 15 year study. Cortisol samples were collected from young adult offspring at the final time point. Findings revealed that higher levels of maternal depressive symptoms during late childhood were associated with lower total cortisol output in young adulthood. Results suggest that attenuated cortisol levels, which put these young adults at risk for a variety of stress-related physical and psychological illnesses, may be a long-term consequence of exposure to maternal depression,. Depressive symptoms in mothers during their child's adolescence, however, did not relate to cortisol output. These findings suggest a sensitive period in late childhood during which the development of HPA activity may be susceptible to the environmental stressor of maternal depression.

The purpose of our study was to evaluate whether viewing videos of dogs had an effect on the stress response of college students. While there is strong support in the literature for demonstrating the beneficial effect of human-canine interactions on human stress indicators, there is very little to no literature on whether or not this phenomenon translates across a digital medium. We hypothesized that when exposed to a video of golden retriever puppies after a stress-inducing task, an individual would experience an increase in blood pressure recovery rate and a decline in perceived stress. In order to study this, we put together several surveys to test our participants' perceived stress, and we measured blood pressure several times in order to obtain a physiological measure of stress. Additionally, in order to produce a guaranteed stress response in our participants, we gave them 2 minutes to prepare a 4 minute video-recorded speech that they were not made aware of prior to entering the testing facility. After the speech task, the experimental group quietly viewed a pleasant 4 minute video containing imagery of dogs, while the control group sat silently for the same duration of time. During this time, the control group was asked to mentally review their performance and to focus intently on the feelings they experienced while giving their speech. Through these measures we found a significant recovery rate in systolic blood pressure and a trending difference between groups for the decline in negative affect. The data demonstrated that the experimental group had blood pressure levels that were significantly closer to their baseline levels when compared to the control group, whose blood pressure did not decline at the same rate. Additionally, the experimental group experienced a higher level of change in negative affect when asked to self-report their level of stress before the speech task and after the conditional recovery period. Interestingly, these findings can be applied to recent literature suggesting that systolic blood pressure is the most important factor of cardiac health to consider when assessing an individual for risk of heart disease or cardiac arrest. While the sample size of this study was small, the significant reduction in systolic blood pressure within the experimental group could indicate the possible efficacy of utilizing digital media containing imagery of canines as a form of therapy for systolically-hypertensive individuals as a means of managing their condition.

Emerging adulthood (18 – 28 years) is a distinctive period in the life course whereyoung people are involved in the process of transitioning to adult roles in their careers and social relationships. Due to the ongoing COVID- 19 pandemic, economic instability, and other social factors, emerging adults in the United States are experiencing greater stress and challenges than ever before. In this climate of high stress, personal characteristics such as an individual’s propensity to endorse sociotropy (the tendency to focus primarily on relationships) or autonomy (the tendency to focus primarily on the self) may be associated with experiences of stress and resulting depressive feelings based on the diathesis-stress model of depression proposed by Beck in 1967. However, perceived partner’s dyadic coping may buffer against the positive association between stress and depression. Despite this plausible link, not much is known about how personal characteristics (here sociotropy and autonomy) of emerging adults may influence their perceptions of their own as well as partner’s dyadic coping. To address this gap, the present study used survey data from 269 emerging adults to examine whether personal characteristics such as sociotropy and autonomy are associated with their perceptions of dyadic coping and to examine if these associations are moderated by perceived relationship commitment, given commitment has been found to increase relationship maintenance behaviors. Results found that both sociotropy and autonomy were associated positively with positive dyadic coping by self and negatively with negative dyadic coping by partner. Relationship commitment partially moderated these associations. Results of this study have the ability to inform therapy for emerging adults in romantic relationships who may be experiencing higher stress, symptoms of depression, and those who may be experiencing difficulties in their relationships. Limitations and future directions for research are discussed

Childhood obesity is associated with many well established health risks as well as high annual public health costs. Because of this, the childhood obesity literature has highlighted the need to detect at-risk groups in order to implement targeted preventions. Emotional eating has been identified as an unhealthy behavior and a risk factor for overweight status among children though very little is known about what predisposes children to emotionally eat. Stress has often been found to elicit emotional eating but most studies looking at this relationship have relied on self-reports in adult and clinical samples. Thus, the current study seeks to investigate the relationship between stress reactivity (measured using heart rate variability) and emotional eating in a sample of 247 children between the ages of 4-6. Furthermore, levels of control may moderate the relationship between stress reactivity (HRV) and emotional eating. Linear regression analysis was used to explore these relationships. It was expected that higher levels of reactivity to stress would predict an increased likelihood of emotional eating. This association was expected to be attenuated among children with higher levels of inhibitory control and attentional focusing as well as lower levels of impulsivity. However, the hypothesized findings were not supported by the data. Despite these null findings, and in light of several limitations, it is still hypothesized that emotional eating involves physiological and impulsivity/effortful control processes. Implications of future research are discussed.

Theoretical models support conceptualizing parent-child relationships as reciprocal and transactional with each person exerting influence on the other’s behaviors and the overall quality and valence of the relationship across time. The goals of this study were twofold: 1) determine whether there were reciprocal relations in maternal hostility and child negativity across early and middle childhood, and 2) investigate whether individual characteristics (i.e., child temperamental anger and frustration and maternal neuroticism) moderated relations found in goal one. Data were from the Study of Early Child Care and Youth Development. Empirical support was found for conceptualizing mother-child interactions as reciprocal. Maternal hostility was related to a decrease in the probability children would exhibit negative behaviors during mother-child interactions measured approximately two years later. Child negativity was also associated with a significant decrease in the probability mothers would display future hostility.

Child temperamental anger and frustration was found to moderate reciprocal relations across all three parent-to-child cross-lagged paths. Children scoring high on a dispositional proclivity to react with anger and frustration were more likely to avoid maternal hostility, via a significant decrease in negativity, across time. Moderation was also supported in two of three child-to-parent lagged paths. Finally, maternal neuroticism moderated the reciprocal effects during early childhood, such that more neurotic mothers were more likely to demonstrate a decrease in the probability of hostility relative to mothers scoring lower on neuroticism. This affect was attenuated in middle childhood, with patterns becoming similar between mothers scoring high and low on neuroticism. Moreover, children of less neurotic mothers were more likely to demonstrate a decrease in the probability of exhibiting negativity from 36 to 54 months compared to children of more neurotic mothers. This effect also attenuated with patterns becoming negative at the grade 1 to grade 3 lag. Overall, the results from this study supported a transactional model of parent-child relationships, were consistent with the motivation literature, did not support a coercive process of interaction when the sample and measurement paradigm were low-risk, and generally suggested parents and children have an equal influence on the relational processes investigated from early to middle childhood.

Longitudinal data from European-American (EA) and Mexican-American (MA) families (n = 179 mothers, fathers, and youth; 41% MA) was used to test a bio-psycho-cultural model of the effect of non-responsive parenting on externalizing problems in young adult offspring through the effect on the stress response system. Parenting behavior (acceptance, rejection, harsh discipline) was assessed when children were in late childhood (12-13 years), cortisol samples were collected during late adolescence (18-19 years), and externalizing problems were measured in young adulthood (21-22 years). Latent profile analyses were used to examine patterns of parenting behavior in EA and MA families. A path analysis framework was used to examine how non-responsive parenting interacted with acceptance to predict adolescent stress response and subsequent externalizing problems in EA and MA young adults. Results showed different patterns of parenting behavior in EA versus MA families, with MA families demonstrating a profile of high acceptance and high non-responsiveness at higher rates than EA families. In MA families, youth adherence to the traditional cultural value of familismo related to more positive perceptions of parenting behavior. Across ethnic groups, parent rejection only predicted higher externalizing problems in young adults when acceptance was high. The effect of parent harsh discipline on offspring stress response differed by ethnicity. In MA families, harsh discipline predicted dysregulated stress response in youth when acceptance was low. In EA families, harsh discipline did not relate to youth stress response. Overall, results increase the understanding of normative and adaptive parenting behaviors in MA families. Findings inform the development of culturally-competent parenting-focused interventions that can better prevent dysregulated stress response and externalizing behavior problems in ethnically diverse youth.
