Description
A study was undertaken to examine and test the effectiveness of a self-experimentation model, guided by a mobile app called PACO, in helping college students improve behaviors associated with sleep. Thirteen participants were enrolled in this study and their nightly sleep quality and sleep duration were measured via PACO as they underwent three conditions: a baseline non-intervention phase, an expert-developed intervention phase, in which pre-made intervention examples were provided and used in PACO, and a self-experimentation phase, during which users were invited to develop their own sleep-behavior interventions using PACO. The participants were randomly placed into three groups, and the points of transition between phases was staggered across five weeks according to a multiple baseline design. The goal and hypothesis was to determine if sleep duration and sleep quality (sleep satisfaction) were improved in the final self-experimentation phase compared to the expert-developed experimentation phase and baseline phase, as well as in the expert-developed experimentation phase compared to the baseline phase. The results show little change, and nearly no improvement in the outcome measures between phases, leaving us unable to support the hypothesis. However, the existence of several limitations considered in retrospect, such as the small sample size, the short study time period, and technical difficulties with the PACO application means that no concrete conclusions should be made regarding the effectiveness of the self-experimentation model, nor the usability of PACO. Additional research should be made toward user motivation and modes of teaching the underlying behavioral science principles to casual users to increase effectiveness.

Description
This paper analyzes existing literature regarding how excessive aggravating stimuli in a hospital environment can reduce the quality and quantity of sleep. The sick and injured are most sensitive to aggravating stimuli and the most vulnerable to poor sleep conditions. For individuals with anxiety, stress, hypersensitivity, or conditions such as Autism Spectrum Disorder (ASD), as additional stress during rest periods could seriously harm development and overall well-being. While solutions have been proposed and tested, there is no one solution to the problem. One possible solution is to design a device that monitors a patient's room and alerts a nurse or parent of aggravating stimuli so that it can be removed.

Description
Circadian misalignments in terms of eat and sleep cycles, common occurrences among college students, are linked to adverse health outcomes. Time-restricted feeding, a form of intermittent fasting, may offer an exciting, non-pharmacologic approach to improve the health of this population by restricting eating to feeding windows that align with circadian biology. This study aims to fill a gap in the literature regarding the effect of early time-restricted feeding (eTRF) on college students, particularly in regard to diet quality, diet self-efficacy, and sleep quality. To test the hypothesis that eTRF would lead to an increase in all three variables, a 4-wk randomized-controlled, parallel arm trial was conducted. Thirty-five healthy college students were randomly assigned to one of two groups: the intervention group (TRF) was instructed to adhere to an 8-h feeding window aligned with the light cycle (9 am to 5 pm), and the control group (CON) was instructed to adhere to a 12-h feeding window typical of college students (10 am to 10pm). The eTRF diet was consumed ad libitum, and the participants were not instructed to avoid compensatory hyperphagia. The results showed a strong, reverse effect of eTRF on diet quality: fasting had a highly significant association with decreased diet quality. The results suggest that, under free-living conditions, college students practicing eTRF are more likely to compensate for prolonged fasting with unhealthy eating and snacking.

Description
How early life is experienced and perceived can greatly affect mental and physical health outcomes. An individual is greatly influenced by their first models of what social relationships look and feel like, and with time also learn how to survive when less favorable social experiences occur. The lessons learned may lead to healthy problem solving and resilience, or it may lead to unhealthy problem-solving habits that hinder well-being. Anxious thoughts and other mental health symptoms may accompany an individual long-term and hinder an essential need for a healthy life. The first main purpose of this thesis is to examine the impact of Adverse Childhood Experiences (ACEs) on mental health (anxiety symptoms), and on sleep quality (an essential need). The second purpose of my thesis is to investigate the impact of genetics on resilience, specifically, the mu-opioid receptor gene. The first hypothesis proposed ACEs that were perceived as more traumatic and occurred more frequently would be associated with more poor sleep quality symptoms. The second hypothesis predicted that anxiety symptoms would mediate the association. The third hypothesis (exploratory) suggested that an individual’s alleles for the mu-opioid receptor gene would moderate the mediation pathway. The study was conducted with 318 participants between the ages of 18 and 35 years old. The study demonstrated a direct effect for ACEs and sleep. Anxiety mediated the association between ACEs (exposure and severity) and sleep (insomnia, quality, sleepiness), suggesting that ACEs possibly increase feelings of anxiety which, in turn, lead to worse sleep outcomes. Finally, the moderated-mediation model with OPRM1 as the moderator, was not significant for the mediation pathway A; however, there was a significant interaction with anxiety and sleep symptoms.

Description
The transition from high school to college (TTC) is a critical period of change, the effects of which may be exacerbated for Latino students, who often face additional minority-specific stressors, such as ethnic/racial discrimination (ERD). Research has documented links between ERD and sleep outcomes in adolescents, but less is known regarding the longitudinal impacts of ERD experiences during unique risk periods (e.g., TTC). Further, despite the central role of family in Latino adolescents’ lives, less research has explored the protective role of family factors (e.g., familism, family support) in links between ERD and Latino students’ sleep health. Thus, this study examined: 1) longitudinal associations between peer- and adult-perpetrated ERD in high school and actigraphy-measured (e.g., duration, efficiency, midpoint) and subjective sleep (e.g., problems) during the first year of college among Latino adolescents, accounting for college ERD experiences, and 2) familism and family support as potential moderators of these associations. Participants were 209 Hispanic/Latino adolescents (Mage=18.10; 64.4% female; 84.7% Mexican descent; 67.9% first-generation students) assessed at two time points (i.e., last semester of high school and second semester of college). There were no longitudinal associations between high school ERD and college sleep. However, there were concurrent associations between ERD and sleep in college. Specifically, greater college peer- and adult-perpetrated ERD were associated with less duration and lower efficiency at the same time point. Further, more college adult-based ERD was additionally linked with greater sleep problems. There were no significant moderation findings; however, the interaction between high school adult-based ERD and family support predicting college sleep problems suggested that adolescents reporting low levels of adult ERD in conjunction with higher levels of family support had the fewest sleep problems. Study findings provide additional evidence that ERD from both adults and peers is associated with reduced sleep duration and quality among Latino college students and suggest that current cultural stressors may be particularly influential on sleep during major socio-contextual shifts. These findings can inform future programs (e.g., sleep interventions) that provide support for students experiencing race-based stressors, such as ERD, to promote Latino student health and well-being.

Description
This body of research sought to explore relationships between cognitive function and physical activity (PA), sedentary behavior (SB), and sleep, independently and in conjunction, in mid-life to older adults with no known cognitive impairment. Aging is associated with cognitive decline, and lifestyle behaviors such as PA, SB, and sleep, may mitigate this decline. First, a systematic review and meta-analysis was conducted to examine the effect of aerobic PA interventions on memory and executive function in sedentary adults. Second, a longitudinal study was conducted to examine the association between SB and odds of incident cognitive impairment, and SB and cognitive decline in older adults. Last, a cross-sectional study was conducted to examine the joint associations between different levels of sleep with levels of PA, and sleep with levels of sedentary time on memory and executive function. This body of research provided evidence to support the association between aerobic PA and improved cognitive function, SB and incident cognitive impairment and cognitive function declines, and the joint association of sleep and different levels of PA and ST on cognitive function by hypertension status.

Description
Experiencing poor, unrefreshing sleep is a common occurrence for individuals with chronic pain. Sleep disturbance predicts not only greater pain and disability, but also heightened negative affect and reduced positive affect in individuals with chronic pain. Such fluctuations in affect have been linked with more negative and fewer positive social events. For those with chronic pain, negative social relations can exacerbate pain, whereas positive social interactions can help decrease disability. Thus, exploring the sleep‒social functioning process in chronic pain may be one way to improve daily functioning and quality of life. The current study examined positive and negative affect as two parallel mediators of the within-day relations between sleep quality and positive and negative social events in individuals with chronic pain. For 21 days, electronic daily diary reports were collected from 220 individuals with fibromyalgia, a condition characterized by widespread chronic pain. Within-person relations among reports of last night’s sleep quality, afternoon affects and pain, and evening social events were estimated via multilevel structural equation modeling. Findings showed that positive affect mediated both the sleep quality‒positive social events and sleep quality‒negative social events relations. That is, greater than usual sleep disturbance last night predicted afternoon reports of lower than usual positive affect. Low positive affect, in turn, predicted evening reports of fewer than usual positive social events and more than usual negative social events that day, controlling for the effects of afternoon pain. In addition, negative affect mediated the sleep quality‒negative social events link. That is, greater than usual sleep disturbance last night predicted afternoon reports of higher than usual negative affect, which, in turn, predicted evening reports of more than usual negative social events that day, controlling for the effects of afternoon pain. Of the three significant mediated paths, the sleep quality‒positive affect‒positive social events path was the strongest in magnitude. Thus, a night of poor sleep can have an impact on social events the next day in those with chronic pain by dysregulating affect. Further, findings highlight the key role of positive affect in the sleep‒social functioning process and potential socio-affective benefits of sleep interventions in chronic pain.

Description
Chronic pain is common during childhood and has negative immediate and long-term implications for physical and mental health. Prior research points to physical activity and sleep as protective health-promoting behaviors predicting lower chronic pain intensity and disability during adulthood. No study has yet examined the interaction of physical activity and sleep parameters in prediction of chronic pain in a community sample of children. Guided by the biopsychosocial model of pediatric chronic pain, this study explored objectively assessed physical activity and sleep patterns at age 8 as predictors of childhood chronic pain at age 9 in a racially/ethnically and socioeconomically diverse sample of 896 twins participating in the longitudinal Arizona Twin Project. It was hypothesized that parameters of physical activity levels and sleep health would independently predict chronic pain one year later, and that sleep parameters would moderate the association between physical activity and chronic pain. Monthly chronic pain was common, with 57.1% of participants reporting at least one pain location. Headaches, stomachaches, and backaches were the most frequent chronic pain presentations. Participants exceeded physical activity guidelines but did not meet sleep recommendations for their age group. Multilevel modeling analyses revealed that physical activity and sleep parameters at age 8 did not predict chronic pain one year later, and that sleep parameters did not moderate the associations between physical activity and chronic pain. The present study provides evidence that the associations between objectively assessed physical activity and sleep and chronic pain are not yet evident during middle childhood in this community sample compared to patient samples who have existing pain, suggesting that these health behaviors may play distinct roles in pain development versus pain management. They also point to the need to pinpoint the time frame during which these health behaviors become relevant and potentially interact to predict chronic pain development and maintenance. Longitudinal research tracking these health behaviors and pain using both subjective and objective methods as children transition into and through adolescence can help to identify optimal developmental stages at which to target prevention and intervention efforts to promote long term health.

Description
Food insecurity affects more than 10 million households in the United States and has been shown to impact what and how a child is fed. Additionally, there is some evidence to suggest that food insecurity may affect how an infant is soothed (either with food or another mechanism), but no study has examined the possible relationship between soothing techniques and the incidence of food insecurity. To evaluate whether food security status and nighttime soothing techniques have a relationship, surveys were administered to a sample of mothers from various racial and socioeconomic backgrounds at 3-weeks, 8-weeks, and 3-months postpartum. Of the 69 participants sampled, 61 had data that could contribute to evaluations of food security status and soothing techniques used at night. A chi-square model was utilized to determine what, if any, relationship existed between the two variables. The chi-square model did not yield statistically significant results (Pearson Chi-Square= .506, p=.477) and descriptive statistics showed that just six of the 61 participants sampled did not use food to soothe at the time their baby was 3-weeks-old. Further examination of descriptive statistics revealed that, between breastfeeding and bottle-feeding as a means to soothe an infant, breastfeeding was used twice as much as bottle-feeding. For participants enrolled in the Special Supplemental Nutrition Program for Women, Infants, Children (WIC), the use of food to soothe increased at each of the three time points. Among participants found to be food-insecure, the use of breastfeeding and bottle-feeding as means to soothe varied from time point to time point. The physical and mental toll of the postpartum period may contribute to the high use of food-to-soothe among mothers seen in this study. Future research efforts in this area should examine whether the observations reported in this study are similar among larger samples, and if more mental health support for mothers has any effect on whether food is used to soothe.

Description
A sense of closeness (or intimacy) is important in nearly every relationship in life, whether it is within friendships, family, or romantic relationships. In the current thesis, intimacy is measured within four specific dimensions: emotional, physical, intellectual and spiritual. Research shows that intimate relationships have been linked to mental and physical health outcomes. In addition, there is a novel explanation for the link between intimacy and health through rumination and sleep quality. The current study examined 2 primary aims: 1) to examine the relationship between intimacy and depression ; 2) to assess the role of intimacy, rumination and sleep quality on mental and on physical health. Results for Aim 1 suggest that there is a link between intimacy and both depression and physical health; where the higher the intimacy the lower the depression and the better physical health. For Aim 2, results indicated that there was a significant serial relationship between intimacy, rumination, sleep quality and both depression and physical health; where in the first model, higher intimacy predicted less rumination, better sleep quality, and lower depression; and, in the second model higher intimacy predicted less rumination, better sleep quality and higher physical health. The current study suggests that intimacy does have its own distinct contributions to health outcomes and that rumination and sleep quality do have a implication on intimate relationships.
