Objective Measures And Insight Assessments Of Muscle Dysmorphia, Austin Blake Lowe

Masters Theses & Specialist Projects

Muscle dysmorphia is a relatively new psychological disorder primarily affecting males who engage in weightlifting or bodybuilding. Individuals with this disorder are obsessed with the idea that their body is not sufficiently lean or muscular when compared to others and engage in several, risky behaviors (i.e., frequent exercise sessions, anabolic steroid use, structured diets) to increase muscularity. As obtaining and maintaining a muscular physique is so important to his or her self-worth, an individual may have little insight to how their behaviors are affecting their social and occupational lives and are reluctant to seek out psychological treatment. The purpose of …

Development And Testing Of The Home Safety And Beautification Checklist With Mothers Referred For Child Neglect And Substance Abuse, Michelle Pitts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Unintentional injury is the leading cause of death among children in the United States accounting for nearly 40 percent of deaths in this age group. Approximately 50 percent of nonfatal injuries, and 40 percent of fatalities, occur in and around the home. Elevated rates of child injury in the home environment are associated with parental substance abuse and neglectful behaviors. Childhood injuries are preventable, yet practical and cost-effective measures to identify child home safety risks are limited. This study involved a retrospective preliminary examination of the Home Safety and Beautification Checklist (HSBC) in a sample of drug-abusing mothers referred by …

Predictors Of Major Commitment, Anna Jill Womack

Master's Theses

Contextual (e.g. job fit, job involvement), individual (e.g. job satisfaction, need for achievement), and demographic (e.g. gender, educational level) factors have been related to forms of career commitment (i.e. affective, continuance, and normative commitment), highlighting that the commitment one feels toward his or her career is a complex variable. Furthermore, commitment has been associated with intent to remain within a profession or organization (Bowling, Beehr, & Lepisto, 2006; Den Hartog & Belschak, 2007; Duffy, Dik, & Steger, 2011; Goulet & Singh, 2002), suggesting that commitment is an important component of retention within a career.

The method was tested on a data set gathered from 276 subjects eating 518 courses consisting of 22,383 marked individual consumption events in a cafeteria environment. Approximately 30% of the consumption events can be detected and weighed. The remaining 70% of the events occur without participants interacting with the scale or when noisy interactions with the scale prevent weight measurement. The relationship between bite …

Reduced Intestinal Brain-Derived Neurotrophic Factor Increases Vagal Sensory Innervation Of The Intestine And Enhances Satiation, Jessica E. Biddinger, Edward A. Fox

Department of Psychological Sciences Faculty Publications

Brain-derived neurotrophic factor (BDNF) is produced by developing and mature gastrointestinal (GI) tissues that are heavily innervated by autonomic neurons and may therefore control their development or function. To begin investigating this hypothesis, we compared the morphology, distribution, and density of intraganglionic laminar endings (IGLEs), the predominant vagal GI afferent, in mice with reduced intestinal BDNF (INT-BDNF_/_) and controls. Contrary to expectations of reduced development, IGLE density and longitudinal axon bundle number in the intestine of INT-BDNF_/_ mice were increased, but stomach IGLEs were normal. INT-BDNF_/_ mice also exhibited increased vagal sensory neuron numbers, suggesting that their survival was enhanced. …

The Influence Of Cumulative Risk Factors On The Cognitive Abilities Of Low-Income, African- American Preschool Children, Cassandra L. Esposito

Master's Theses and Doctoral Dissertations

A large number of children are exposed to multiple risk factors within the first 3 years of life, resulting in poorer child developmental outcomes. Additionally, exposure to multiple risks is especially prevalent in low-income populations. Several studies have found that multiple maternal and biological risks such as maternal depression, physical health or illness, other sociodemographic risks, and low birth weight lead to poor child outcomes, such as lower cognitive achievement at preschool age. The current study investigated the influence of both maternal and infant biological risks in a cumulative risk model on predicting preschool children’s cognitive outcomes. Hierarchical multiple regression …

Premenstrual Experiences: The Simultaneous Examination Of The Association Of Self-Perceived Stress, College-Related Stress, And Sleep Quality, Sara Julia Gonzalez

Theses and Dissertations - UTB/UTPA

Research suggests that stress may contribute to the severity of premenstrual experiences, but the contribution of different types of stress has not been carefully examined. Using self-report measures, the current study examined the relation between self-perceived stress, college-related stress, sleep quality, and premenstrual experience in a predominantly Hispanic female college sample. Results indicated that self-perceived stress accounts for a statistically significant proportion of the variance in premenstrual experience ratings, with higher stress associated with greater premenstrual distress. Based on a hierarchical regression analysis, adding college-related stress to the predictive model allows for a significantly larger amount of the variance in …

The Effects Of Cultural Orientation Change On Metabolic Health In A Sample Of Mexican Immigrants To The United States, Jillian L. Walker

Theses and Dissertations

Studies have identified metabolic health factors to be a major concern in Mexican-Americans, including Mexican immigrants to the United States (U.S.). Acculturation stress has been hypothesized to be a factor in the development of many health-related concerns in this population. Specifically, previous studies have shown that acculturation stress contributes to health concerns, including metabolic health concerns (e.g., diabetes, metabolic syndrome). The primary purpose of this study was to examine the relationship between cultural orientation, a measure of acculturation designed to provide more information than traditional acculturation measures, and metabolic health outcomes. Specific acculturation-related stressors (social support, job-related stress, and depression) …

Testing The Correlation Between Response Latency, Derivation, And Complexity, Jeffrey Ryan Oliver

USF Tampa Graduate Theses and Dissertations

This study investigates the constructs of Derivation and Complexity and how they relate to latency. Derivation and Complexity are theoretical constructs that have been posited as two of the main factors in differences in latency to responding in implicit measures such as the Implicit Relational Assessment Procedure (IRAP) and the Implicit Association Task (IAT). This study trained participants to relate two groups of novel stimuli in a linear fashion and then tested their latency to responding to derived relations (relations based on previously trained relations, but not directly trained themselves). The study then analyzed participant's latency to responding after dividing …

Acute Aerobic Exercise: An Intervention For The Selective Visual Attention And Reading Comprehension Of Low-Income Adolescents, Michele Tine

Dartmouth Scholarship

There is a need for feasible and research-based interventions that target the cognitive performance and academic achievement of low-income adolescents. In response, this study utilized a randomized experimental design and assessed the selective visual attention (SVA) and reading comprehension abilities of low-income adolescents and, for comparison purposes, high-income adolescents after they engaged in 12-min of aerobic exercise. The results suggest that 12-min of aerobic exercise improved the SVA of low- and high-income adolescents and that the benefit lasted for 45-min for both groups. The SVA improvement among the low-income adolescents was particularly large. In fact, the SVA improvement among the …

Using The Objectification Theory Framework To Assess The Unique Body Image Concerns Of Women Experiencing Homelessness, Melanie K. Mitchell

Honors Program Theses and Projects

The primary objective of this research is to explore the unique body image concerns of women experiencing homelessness, an understudied population in body image research. The hypothesis is that women who are currently homeless and who have experienced longer periods of homelessness will be more likely to have poorer body image. Homeless women may not possess the means to modify their appearance with hygiene products or facilities (Hoffman & Coffey, 2008). Also, an inconsistent food source may influence some women to binge when food is available, or to eat unhealthy foods that result in weight gain (Bove & Olsen, 2006). …

Healthy Living Skills Education: A 12-Module Group Intervention For Individuals With Serious Mental Illness, Brette Marie Stephenson

Educational Specialist, 2009-2019

"Can’T Touch This": Empowering Children With Severe Food Allergy In The Residential Camp Setting 2014, Alexsandra Dubin

Master's Theses

The purpose of this project was to create an empowerment program for children with severe food allergy (SFA) in a residential camp setting. Despite recent advancements in research, there is no cure for SFA, thus there is a need for programs to help children manage their allergies and cope with the ramifications of their condition. Quality of life is a major concern for children with SFA, as the constant fear of exposure to an allergen can lead to high levels of anxiety. This is particularly noteworthy because, barring exposure to an allergen, these children are otherwise healthy and symptom free. …

Juvenile Domestic Pigs (Sus Scrofa Domestica) Use Human-Given Cues In An Object Choice Task, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell

Social Cognition Collection

Research on the comprehension of human-given cues by domesticated as well as non-domesticated species has received considerable attention over the last decade. While several species seem to be capable of utilizing these cues, former work with domestic pigs (Sus scrofa domestica) has shown inconclusive results. In this study, we investigated the use of human-given cues in an object choice task by young domestic pigs (N = 17; seven weeks of age) who had very limited human contact prior to the experiments. Subjects had to choose between two bowls of which only one was baited with a reward. Over the course …

The Impact Of Childhood Experiences On Intrapersonal And Interpersonal Functioning: Does The Past Dictate The Future?, Anna W. Vandevender

USC Aiken Psychology Theses

Childhood experiences of maltreatment are related to interpersonal difficulties in childhood (Pettit, Dodge, & Brown, 1988) and adulthood (Messman-Moore & Coates, 2007; Varia & Abidin, 1999; Busby, Walker, & Holman, 2011). However, most studies have examined the effects of maltreatment on interpersonal functioning (Messman-Moore & Coates, 2007; Busby, Walker, & Holman, 2011) within the context of romantic relationships (Hazan & Shaver, 1987; Feeney & Noller, 1990). Thus, the present study examined the impact childhood maltreatment and neglect has on later intrapersonal functioning and interpersonal interactions and whether gender differences emerge therein. Results indicated maltreated individuals initiate relationships less often and …

The Effect Of Self-Licensing On Food Choice, James Force

Theses, Dissertations and Culminating Projects

Research has shown that individuals will license indulgent or immoral behavior after engaging in or recalling moral behavior. The purpose of this experiment was to determine whether or not individuals would do this when selecting food items. Participants completed one of two writing tasks, one of which was designed to elicit a licensing effect, before choosing a food item. Afterward, participants completed a scale to determine their restraint type. It was hypothesized that individuals who recalled moral behavior would allow themselves to indulge and choose an unhealthy, high calorie food item over a healthy, low calorie food item. It was …

Olfactory Identification, Detection Thresholds, And Sensitivity In Kidney Disease Patients, Joseph Wesley Jones

Masters Theses and Doctoral Dissertations

While there is evidence for a decline in olfactory identification scores for patients with Kidney Disease, there are contradictory results for detection thresholds. Some results indicate higher thresholds while others found similar thresholds or elevated thresholds for one odorant, but not others. The current study evaluated the olfactory abilities with participants diagnosed with Kidney Disease for numerous odorants. No significant differences were found in olfactory identification, detection thresholds, or sensitivity compared to healthy controls. Despite the non-significant results, there did appear a trend of poorer olfactory abilities in Kidney Disease participants. The differences in olfactory performance also varied from odorant …

Family Environment And Severity Of Absenteeism In Youth, Rachel Marie Loftis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the relationship between family environment and severity of youth absenteeism in clinical and community settings. Previous researchers have adopted a categorical approach to investigating the role of family environment in problematic absenteeism by diving youth into discrete categories and these studies are almost exclusively conducted in clinical settings. The current study contributes to the literature by adopting a dimensional approach that examines the impact of family environment on problematic absenteeism across diagnostic and functional categories.

The first aim of the study was to determine the family environment characteristics most predictive of absenteeism severity. The first hypothesis …
