Evaluating Public Posting, Goal Setting, And Rewards To Increase Physical Activity In Children, Bryon G. Miller

USF Tampa Graduate Theses and Dissertations

In Experiments 1 and 2 we evaluated a pedometer-based intervention consisting of public posting between two teams of students, with additional self-monitoring, goal setting, and reinforcement components, to increase physical activity during school recess. In the absence of self-monitoring, performance feedback alone did not increase physical activity levels above those observed during baseline. Additionally, higher levels of physical activity were observed when goal-setting was introduced, with the highest levels of activity observed when raffle tickets could be earned for exceeding a specified step-total goal. In Experiment 3 we removed the team component and evaluated similar intervention components across an entire …

Treatment-Associated Improvements In Self-Regulation And Mood As Theory-Based Correlates Of Increased Self-Efficacy For Weight-Management Behaviors, James J. Annesi

Health Behavior Research

Expanded understanding of the psychosocial dynamics of weight-loss treatment processes is required to improve consistently poor results. Women with obesity of ages 40–59 years participated in self-regulation-based (n = 41) and information-based (n = 46) treatments. Improvements in self-regulation and self-efficacy related to exercise and eating, mood, exercise, intake of fruits/vegetables and sweets, and weight were significant, and generally greater in the self-regulation group. Exercise- and eating-behavior changes significantly mediated the prediction of self-efficacy changes by changes in self-regulation, with mood change significantly adding to the prediction strength. Findings suggested the value in supporting exercise for its psychosocial …

The Moderating Effects Of Parenting Factors And Perceived Stress On African American Adolescent Weight Related Outcomes, Colby Kipp

Theses and Dissertations

African American adolescents experience a higher prevalence of obesity than nonminorities with approximately 40% being overweight or obese. Chronic stress, both among parents and adolescents, may be important to consider when assessing the factors that influence adolescent weight status. Baseline data were collected from one hundred forty eight African American adolescents (M_age = 12.93, SD = 1.75; M_BMI% = 96.7, SD = 3.90) and their caregivers (M_age = 44.5, SD = 8.6; M_BMI = 37.63, SD = 8.21) enrolled in the Families Improving Together (FIT) for Weight Loss trial. Adolescents self-reported their perceptions of …

Summary

Introduction: Obesity is linked to altered activation in reward and control brain cir-cuitry; however, the associated brain activity related to successful or unsuccessful weight loss (WL) is unclear.

Methods: Adults with obesity (N = 75) completed a baseline functional magnetic res-onance imaging (fMRI) scan before entering a WL intervention (ie,3-month diet and physical activity [PA] program). We conducted an exploratory analysis to identify the contributions of baseline brain activation, adherence behavior patterns, and the asso-ciated connections to WL at the conclusion of a 3-month WL intervention. Food cue-reactivity brain regions were functionally identified using fMRI to index brain activation …
