Graduate Research Posters

Introduction: The consequences of recurrent, stressful daily experiences for sleep health appear intensified in individuals with pre-existing health conditions. Although discrimination has been associated with sleep outcomes, the role of comorbid chronic health conditions (CCHCs), and impact of perceived discrimination, remains unclear. The present study investigated (1) the associations between daily discrimination and sleep and (2) moderating roles of CCHCs and daily life interference and hardship.

Methods: The current study utilized archival data from the Midlife in the United States (MIDUS) Study II. Participants, 174 adults (51% female, M_age=57 yrs., SD=11.5 yrs.), completed 7 days of actigraphy, …

Examining Sleep And Family Functioning In Pediatric Craniopharyngioma Using Ecological Momentary Assessment, Nour Al Ghriwati

Theses and Dissertations

Craniopharyngiomas are among the most common brain tumors in children and are associated with greater rates of sleep problems compared to other pediatric cancers. However, research examining sleep among youth with craniopharyngioma has been limited by a reliance on retrospective reports or sleep studies. Families also play a crucial role in children’s adjustment following a pediatric cancer diagnosis, yet remarkably little is known about transactional associations between family functioning and sleep in pediatric cancer. This study examined cross-sectional and daily associations among family functioning, affect, and sleep difficulties for youth with pediatric craniopharyngioma using retrospective reports and ecological momentary assessment …

The Under-Explored Role Of Tiredness In Alcohol Use And Sexual Risk-Taking Among Gay And Bisexual Men, Brett M. Millar

Dissertations, Theses, and Capstone Projects

Numerous factors have been shown to increase the likelihood of risk-taking in the realms of alcohol use and sexual behavior— and many studies have focused on these behaviors among gay and bisexual men (GBM), given the health disparities that exist in substance use and HIV/STI infections. After a brief review of the person- and situation-level variables that have already been identified, I will argue for the relevance of also considering a previously under-explored situation-level factor in alcohol use and sexual risk-taking: sleep-related fatigue, referred to here as tiredness. While tiredness has been shown, in the sleep science literature, to impair …

Sleep, Executive Control, And Psychopathology In Children: A Longitudinal Study And An Examination Of Brief Sleep Treatment, Katherine M. Kidwell

Department of Psychology: Dissertations, Theses, and Student Research

Researchers have acknowledged that poor sleep is not merely a symptom of psychopathology but also a contributing factor to the development of psychopathology in children (Walker & Harvey, 2010). However, more research is needed to explicate the associations among sleep, executive control (EC), and psychopathology. Specifically, there are few studies using longitudinal designs and limited research on how treating sleep can improve mental health symptoms. This dissertation provides a conceptual framework for the associations among sleep, EC, and psychopathology. The conceptual framework is bolstered by two studies. Study 1 is an examination of early sleep problems and preschool EC as …

Daily Bidirectional Relationships Between Sleep And Mental Health Symptoms In Youth With Emotional And Behavioral Problems, Tori R. Van Dyk, Ronald W. Thompson, Timothy D. Nelson

Department of Psychology: Faculty Publications

Objective The present study examined the daily, bidirectional relationships between sleep and mental health symptoms in youth presenting to mental health treatment. Methods Youth aged 6 to 11 (36% female, 44% European American) presenting to outpatient behavioral health treatment (N = 25) were recruited to participate in the study. Children and parents completed daily questionnaires regarding the child’s sleep, mood, and behavior for a 14-day period, while youth wore an actigraph watch to objectively measure sleep. Results Examining between- and within-person variance using multilevel models, results indicate that youth had poor sleep duration and quality and that sleep and mental …

Tired, Hungry, And Grumpy: Understanding The Direct And Indirect Relationships Among Child Temperament, Sleep Problems, Feeding Styles, And Weight Outcomes, Alyssa Lundahl

Department of Psychology: Dissertations, Theses, and Student Research

Research indicates that temperament is related to later obesity risk in both childhood and adulthood (e.g., Anzman-Frasca et al., 2012; Darlington & Wright, 2006), but less research has examined the mechanisms underlying this relationship. It is likely that temperament influences factors that increase one’s risk for obesity, such as parental feeding practices and child sleep problems. As such, the primary aim of the present study was to provide rigorous concurrent and longitudinal examinations of temperament, feeding practices, sleep problems, and child zBMI in a sample of healthy preschool children. In addition, the moderating role of SES was examined. A secondary …

Pathways Linking Sleep Timing To Obesity In Midlife Women, Dana R. Schreiber

Theses and Dissertations

Midlife women are vulnerable to developing obesity. Both sleep timing and negative emotion are risk factors, yet limited research has explored their role on weight outcomes in this population. The current investigation explored the association of sleep timing (i.e., mean sleep time, sleep time variability) and obesity (i.e., BMI, waist circumference) in midlife women, considering emotional pathways (i.e., depressive symptoms, anger) that might mediate this association. PROCESS parallel mediation models assessed direct and indirect pathways. In follow-up analyses, sleep duration was explored as an indirect pathway linking sleep timing to obesity. Results demonstrated that sleep timing does not directly predict …

The Relationship Between Self-Compassion, Sleep Quality, And Perceived Stress Among Undergraduate And Graduate Students, Michael Unger

PCOM Psychology Dissertations

Research has indicated that sleep problems are prevalent in college students. Current studies show that over half of college students report that they are poor-quality sleepers. The consequences of poor sleep quality include increased stress, substance use, and mental health issues. Poor sleep hygiene is one of the many factors that contribute to poor sleep quality in college students. Although research has identified contributing factors and consequences of sleep problems in college students, less attention has been given to factors that may serve as a buffer against the effects of poor sleep quality. This study introduces and discusses self-compassion as …

The Relationship Between Self-Regulation And Stress, Sleep, And Behavioral Health, Clayton I. Brock

CMC Senior Theses

The goal of this research was to investigate multiple aspects of self-regulation and their relationship to stress, sleep, and behavioral health. Participants (N=89, 55 females, 29 males, and 5 did not list their sex) were recruited from a high-risk Midwest high school. Participants reported their own self-regulatory ability, sleep, stress, and behavioral problems. Nail samples were also collected from a subset of the participants to assay for cortisol and DHEA. Several measures of self-regulation were found to correlate with sleep quality, behavioral problems, and perceived stress. The natural log of the ratio of cortisol to DHEA was positively correlated with …

Summertime Sleep And Bmi In Urban Minority Girls: Relations To Physical Activity And Executive Functions, Carolyn Rose Bates

Master's Theses

Urban minority youth, particularly females, are at high risk for increased weight gain during the summertime months, and may also experience insufficient sleep at this time. Few studies have objectively measured summertime sleep in this population or related sleep to weight gain during this season. The current study draws on a sample of 66 urban minority girls aged 10-to-14 who participated in a community-based summer day camp program promoting physical activity (PA). The study objectively characterizes sleep in this sample, both in unstructured and structured contexts. Additionally, the study examines potential pathways underlying summertime relations between sleep and weight, including …

The Relationship Between Sleep And Bmi In Cal Poly Freshman, Jacqueline Laing

Psychology and Child Development

To understand the relationship between BMI and sleep patterns in Cal Poly Freshman (First years) over the course of their first year at Cal Poly. First year students were recruited via campus email to fill out a survey regarding various health aspects. The survey was filled out at the beginning of the year (Fall 2009), and again in June (Spring 2010). The questions used in this study only pertained to height, weight, sleep quantity, and sleep quantity satisfaction rating. The results were not significant for the cross sectional analysis of the Fall 2009 sample and the Spring 2010 sample. The …
