Sleep Self-Efficacy, Loneliness, And Physical Activity: Assessing The Pathways Between Sleep Quality And Mental Health Using Structural Equation Modeling, Amber M. Fox

Theses and Dissertations

Although there is robust empirical support that poor sleep contributes to declines in mental health, explanations of this relationship remain unclear. The purpose of the present study was to examine the pattern of associations between sleep quality, sleep self-efficacy, loneliness, physical activity, and mental health among U.S. adults across the lifespan, and whether they differed by gender or age group. A structural equation model with invariance analysis was developed and examined data from 2,300 adults (M_age = 44.1, SD = 16.78) participating in the online study Investigating Sleep Longitudinally Across Normal Development (ISLAND). Sleep quality was measured by …

Examining Physical Activity Behaviors And Psychometric Beliefs Of College Students Before And After The Covid-19 Shutdown, James White Iii

Graduate Theses

Objectives: The purpose of this study was to examine PA behaviors, social support and self-efficacy for PA, Rosenberg self-esteem, and perceptions of body weight before and after the COVID-19 shutdown (March 15, 2020) among the college demographic.

Participants: 311 college students from a four-year, comprehensive, southeastern university in the United States were included in the study from December 1, 2020 until March 5, 2021.

Methods: Surveys were conducted via Qualtrics, an online survey system, and consisted of approximately 40 items, including demographic information, PA behaviors, social support and exercise, self-esteem, self-efficacy to exercise, and perceptions of body weight and self-image. …

Aerobic Exercise Exposure Targeting Anxiety Sensitivity: Effects On Associated Health Behaviors In Young Adults, Autumn Lanoye

Theses and Dissertations

Anxiety sensitivity (AS) is associated with health behaviors such as low rates of physical activity, overeating, alcohol use, and poor sleep; however, interventions targeting AS via exercise-based interoceptive exposure have not assessed these as outcomes. In addition, previous studies are limited by brief follow-up periods. This study aimed to replicate previous aerobic exercise interoceptive exposures with an extended (6-week) follow-up and measurement of health behaviors.

Participants were 44 sedentary young adults with elevated AS randomized to intervention (6 20-minute sessions of moderate-intensity treadmill walking) or assessment-only control. Assessments took place at baseline, week 2 (post-treatment), week 4, and week 8 …

Examination Of The Monoamine Oxidase A Gene Promoter On Motivation To Exercise And Levels Of Voluntary Physical Activity, Erin M. Kinney

Senior Theses

Purpose: The purpose of this study was to examine the genetic basis underlying voluntary exercise. Monoamine oxidase A (MAO-A) is an enzyme that acts on monoamine neurotransmitters, such as dopamine, to cause inactivation. There are several polymorphisms in the promoter region of the MAO-A gene, and these variations change transcriptional activity and the amount of MAO-A produced, leading to alterations in available dopamine levels. Interestingly, polymorphisms in MAO-A have been associated recently with physical activity level. This study sought to determine whether there is an association between motivation to exercise, levels of voluntary physical activity, and MAO-A gene polymorphisms.

Methods: …

The Effect Of Two Modes Of Aerobic Assessment On Fifth Grade Students' Self Efficacy, Debra Roth

Walden Dissertations and Doctoral Studies

Declining youth physical activity levels and lack of aerobic fitness have been well documented with a corresponding rise in obesity levels and health issues. Based on Bandura's social cognitive theory, healthy physical activity levels and aerobic fitness are strongly connected to positive physical activity self-efficacy beliefs. This study examined whether student physical activity self-efficacy, motivation, and effort were different for the FitnessGram-® (FG) 1-Mile Run when compared to the 15-minute Aerobic Assessment Based on Improvement (AABI). A concurrent mixed method quasi-experimental approach measured 5th grade students' physical activity self-efficacy beliefs through a pretest and posttest survey while aerobic assessment scores …

Awareness Of Physical Activity Levels And Sedentary Behaviour: An Assessment Of Awareness Of Physical Activity Levels And Sedentary Behaviour Among Parents And Children, Tripat Simran Kaur Grewal

Electronic Thesis and Dissertation Repository

The purpose of this study was to assess awareness of physical activity and sedentary behaviour among parents and children aged 10-13 years. Associations between awareness and factors including age, BMI, gender, and obesity status were also examined. A total of 53 parent-child dyads participated in the study. Agreement between parent and child subjective measures (self-report) and objectively measured physical activity was examined to determine awareness. Most parents (87%) and children (83%) overestimated child moderate-vigorous physical activity (MVPA) beyond 30 minutes/day. The majority of parents (87%) and children (85%) also underestimated child sedentary behaviour by at least 3 hours/day. Older children …

The Importance Of Self-Efficacy And Basic Psychological Needs In Children’S Physical Activity: Measurement, Prediction And Intervention, Casey E. Gray

Electronic Thesis and Dissertation Repository

The importance of physical activity in the overall health promotion and primary prevention of cardiovascular disease risk factors and metabolic diseases in children is well established. Nonetheless, interventions to increase physical activity among this population have been largely unsuccessful. The main objective of the research in this dissertation was to explore the suitability of self-efficacy and basic psychological needs for physical activity prediction and intervention in children. Item generation and psychometric evaluation of psychological questionnaires occurred in study 1 (Chapter 2). Using a prospective design, study 2 (Chapter 3) established task efficacy, barriers efficacy, competence, and autonomy as significant predictors …
