Mental Health Benefits Of Physical Activity In Older Adults, Adrian Kurt Zitzmann Dec 2022

Mental Health Benefits Of Physical Activity In Older Adults, Adrian Kurt Zitzmann

Master of Science in Nursing Family Nurse Practitioner

Physical activity is the fountain of youth, strengthening both the physical body as well as the mind, leading to better emotional stability and a general sense of well-being. The population over age 65 is nearing retirement age and are transitioning from a high paced work and family life to a slower and less active “empty nest” lifestyle. Among adults over age 65, will implementing an exercise program for 30 minutes per day increase mental well-being? The benefits of physical activity will be supported by gathering a group of older adults ages 65 and up from a local retirement community to …


Evaluating The Impact Of A Safe Exercise Training Workshop On Knowledge And Self-Efficacy To Manage Dysfunctional Exercise Among Eating Disorders Clinicians At Alsana Eating Disorders Center, Danika A. Quesnel Jun 2022

Evaluating The Impact Of A Safe Exercise Training Workshop On Knowledge And Self-Efficacy To Manage Dysfunctional Exercise Among Eating Disorders Clinicians At Alsana Eating Disorders Center, Danika A. Quesnel

Electronic Thesis and Dissertation Repository

Engaging in dysfunctional exercise (DEX) is detrimental to eating disorders (EDs) prognosis, although common amongst clients. Though nutritionally supported exercise can improve ED treatment outcomes, without negatively impacting weight restoration, clinicians remain hesitant to address DEX, perhaps due to a lack of information and training. The current study examined the effects of a Safe Exercise at Every Stage (SEES) training on clinician knowledge and self-efficacy in managing DEX in ED treatment. Eating disorders clinicians completed measures before (n = 96) and after (n = 44) SEES training to assess their knowledge and self-efficacy around treating DEX, with a …


A Scoping Review Of Behavior Change Techniques Used To Promote Physical Activity Among Women In Midlife, Danielle Arigo, Kelly A. Romano, Kristen Pasko, Laura Travers, M. Cole Ainsworth, Daija A. Jackson, Megan M. Brown Jan 2022

A Scoping Review Of Behavior Change Techniques Used To Promote Physical Activity Among Women In Midlife, Danielle Arigo, Kelly A. Romano, Kristen Pasko, Laura Travers, M. Cole Ainsworth, Daija A. Jackson, Megan M. Brown

Psychology Faculty Publications

Women in midlife experience health risks that could be mitigated by regular physical activity and reduced sedentary time, but this population rarely achieves physical activity levels that would protect their health. As a result, many behavioral interventions are designed to promote physical activity in this population, which are purportedly guided by theoretical models of health behavior (change) and activate an associated set of behavior change techniques (BCTs). The efficacy and effectiveness of these interventions appear to be limited, however, raising questions about their design and adaptation for women in midlife. Several aspects of these interventions are currently unclear. Specifically, which …

Cannabis Use, Sedentary Behavior, And Physical Activity In A Nationally Representative Sample Of Us Adults, Lydia Q. Ong, John Belletierre, Citlali Alvorado, Paul Chavez, Vincent Berardi

Psychology Faculty Articles and Research

Background

Prior research examining the relationship between cannabis use, sedentary behavior, and physical activity has generated conflicting findings, potentially due to biases in the self-reported measures used to assess physical activity. This study aimed to more precisely explore the relationship between cannabis use and sedentary behavior/physical activity using objective measures.

Methods

Data were obtained from the 2005–2006 National Health and Nutrition Examination Survey. A total of 2,092 participants (ages 20–59; 48.8% female) had accelerometer-measured sedentary behavior, light physical activity, and moderate-to-vigorous physical activity. Participants were classified as light, moderate, frequent, or non-current cannabis users depending on how often they used …

Publications and Research

The governmental lockdowns related to the COVID-19 pandemic have forced people to change their behavior in many ways including changes in exercise. We used the brief window of global lockdown in the months of March/April/May 2020 as an opportunity to investigate the effects of externally imposed restrictions on exercise-related routines and related changes in subjective well-being. Statistical analyses are based on data from 13,696 respondents in 18 countries using a cross-sectional online survey. A mixed effects modeling approach was used to analyze data. We tested whether exercise frequency before and during the pandemic would influence mood during the pandemic. Additionally, …


Sense Of Purpose In Life And Five Health Behaviors In Older Adults, Eric S. Kim, Koichiro Shiba, Julia K. Boehm, Laura D. Kubzansky Jun 2020

Sense Of Purpose In Life And Five Health Behaviors In Older Adults, Eric S. Kim, Koichiro Shiba, Julia K. Boehm, Laura D. Kubzansky

Psychology Faculty Articles and Research

Accumulating evidence shows that a higher sense of purpose in life is associated with lower risk of chronic conditions and premature mortality. Health behaviors might partially explain these findings, however, the prospective association between sense of purpose and health behaviors is understudied. We tested whether a higher sense of purpose at baseline was associated with lower likelihood of developing unhealthy behaviors over time. Prospective data were from the Health and Retirement Study, a national sample of U.S. older adults. Our sample included 13,770 adults assessed up to five times across eight years. Among people who met recommended guidelines for a …


A Phenomenological Photovoice Exploration Of Female Exercisers’ Experiences Of Their Body In Fitness Center Environments, Katherine E. Fairhurst Jan 2020

A Phenomenological Photovoice Exploration Of Female Exercisers’ Experiences Of Their Body In Fitness Center Environments, Katherine E. Fairhurst

Graduate Theses, Dissertations, and Problem Reports

For many women, the relationship with their body and exercise is complex. Exercise can have positive effects on body image, however, not all women appear to benefit positively from all types of exercise. To date, body image research has focused on exercise as an activity and less so on the context in which exercise is performed. Women frequently exercise in fitness centers as young adults which, unfortunately, is associated with body dissatisfaction. Using an Interpretative Phenomenological Analysis (IPA) approach with Photovoice methodology, we explored young adult women’s lived body experiences while exercising in fitness centers. A purposive sample of 11 …

Adams, Jane Hurley, Christine Phillips, Michael Todd, Siddhartha Angadi, Vincent Berardi, Melbourne F. Hovell, Steven Hooker May 2019

Rationale, Design, And Baseline Characteristics Of Walkit Arizona: A Factorial Randomized Trial Testing Adaptive Goals And Financial Reinforcement To Increase Walking Across Higher And Lower Walkable Neighborhoods, Marc A. Adams, Jane Hurley, Christine Phillips, Michael Todd, Siddhartha Angadi, Vincent Berardi, Melbourne F. Hovell, Steven Hooker

Psychology Faculty Articles and Research

Little change over the decades has been seen in adults meeting moderate-to-vigorous physical activity (MVPA) guidelines. Numerous individual-level interventions to increase MVPA have been designed, mostly static interventions without consideration for neighborhood context. Recent technologies make adaptive interventions for MVPA feasible. Unlike static interventions, adaptive intervention components (e.g., goal setting) adjust frequently to an individual's performance. Such technologies also allow for more precise delivery of “smaller, sooner incentives” that may result in greater MVPA than “larger, later incentives”. Combined, these factors could enhance MVPA adoption. Additionally, a central tenet of ecological models is that MVPA is sensitive to neighborhood environment …


Delay Discount Rate Moderates A Physical Activity Intervention Testing Immediate Rewards, Christine B. Phillips, Jane C. Hurley, Siddhartha S. Angadi, Michael Todd, Vincent Berardi, Melbourne Hovell, Marc A. Adams Apr 2019

Delay Discount Rate Moderates A Physical Activity Intervention Testing Immediate Rewards, Christine B. Phillips, Jane C. Hurley, Siddhartha S. Angadi, Michael Todd, Vincent Berardi, Melbourne Hovell, Marc A. Adams

Psychology Faculty Articles and Research

Financial incentives can increase physical activity (PA), but differences in the immediacy of reward delivery and individual differences in delay discount rates (i.e., higher discount values associated with less tolerance for delayed rewards) may explain differential responding. The current study tested whether delay discount rate moderated the relative effectiveness of immediate financial rewards on increasing daily PA. Inactive, overweight adults (ages 18–60, N = 96) were randomized to receive either smaller, immediate goal-contingent rewards or larger, delayed rewards for participation. Delay discount rates were derived for those who completed the Monetary Choice Questionnaire (N = 85). Linear mixed models tested …


Self-Management Strategies Mediate Self-Efficacy And Physical Activity, Amanda Birnbaum, Rod K. Dishman, Robert W. Motl, James F. Sallis, Andrea L. Dunn, Greg J. Welk, Ariane L. Yung, Carolyn C. Voorhees, Jared B. Jobe Mar 2019

Self-Management Strategies Mediate Self-Efficacy And Physical Activity, Amanda Birnbaum, Rod K. Dishman, Robert W. Motl, James F. Sallis, Andrea L. Dunn, Greg J. Welk, Ariane L. Yung, Carolyn C. Voorhees, Jared B. Jobe

Amanda Birnbaum

Self-efficacy theory proposes that girls who have confidence in their capability to be physically active will perceive fewer barriers to physical activity or be less influenced by them, be more likely to pursue perceived benefits of being physically active, and be more likely to enjoy physical activity. Self-efficacy is theorized also to influence physical activity through self-management strategies (e.g., thoughts, goals, plans, and acts) that support physical activity, but this idea has not been empirically tested.


The Relationship Between Campus Wellness Center Usage And Symptoms Of Depression In College Freshmen, Allison Leonard Jan 2019

The Relationship Between Campus Wellness Center Usage And Symptoms Of Depression In College Freshmen, Allison Leonard

Electronic Theses and Dissertations

There is limited research done on the relationship between the program utilization at a campus wellness facility and the symptoms of depression in college freshmen. College students have been found to have a higher prevalence of depressive symptoms than the general population, possibly due to the stressors college life can add. Studies have been done on the effects of physical activity as an intervention for depression as well as on the benefits of campus wellness facilities; however, there have been few studies that look at both campus recreation and depression. The author’s purpose for this study was to see if …


Prompts To Increase Physical Activity At Points-Of-Choice Between Stairs And Escalators: What About Escalator Climbers?, John Belletierre, Ben Nguyen, Sandy Liles, Vincent Berardi, Marc A. Adams, Paddy Dempsey, Yael Benporat, Jacqueline Kerr, Andrea Z. Lacroix, Melbourne Hovell Aug 2018

Psychology Faculty Articles and Research

Since 1980, many studies have evaluated whether stair-use prompts increased physical activity by quantifying changes in stair use. To more completely evaluate changes in physical activity, this study addressed the often-overlooked assessment of climbing up escalators by evaluating the degree to which stair-use sign prompts increased active ascent—defined as stair use or escalator climbing. Over 5 months, at an airport stairs/escalator point of choice, we video-recorded passersby (N = 13,544) who ascended either stairs or escalators, on 10 days with signs and 10 days without signs. Ascenders using the stairs, standing on the escalator, and climbing the escalator were …


Neighborhood Cohesion, Neighborhood Disorder, And Cardiometabolic Risk, Jennifer N. Robinette, Susan T. Charles, Tara Gruenewald Dec 2017

Neighborhood Cohesion, Neighborhood Disorder, And Cardiometabolic Risk, Jennifer N. Robinette, Susan T. Charles, Tara Gruenewald

Psychology Faculty Articles and Research

Perceptions of neighborhood disorder (trash, vandalism) and cohesion (neighbors trust one another) are related to residents’ health. Affective and behavioral factors have been identified, but often in studies using geographically select samples. We use a nationally representative sample (n = 9032) of United States older adults from the Health and Retirement Study to examine cardiometabolic risk in relation to perceptions of neighborhood cohesion and disorder. Lower cohesion is significantly related to greater cardiometabolic risk in 2006/2008 and predicts greater risk four years later (2010/2012). The longitudinal relation is partially accounted for by anxiety and physical activity.

Weight-Loss Treatment-Induced Physical Activity Associated With Improved Nutrition Through Changes In Social Cognitive Theory Variables In Women With Obesity, James J. Annesi, Nicole Mareno Oct 2017

Weight-Loss Treatment-Induced Physical Activity Associated With Improved Nutrition Through Changes In Social Cognitive Theory Variables In Women With Obesity, James J. Annesi, Nicole Mareno

Health Behavior Research

Behavioral weight-loss treatments have typically been unsuccessful and a theoretical. Even when treatments were scientifically derived, theory has rarely been used to decompose, and understand the bases of, their effects. This 2-year study evaluated mediation of the prediction of nutritional changes by changes in physical activity, through social cognitive theory variables. Data from women with Class 1–2 obesity, classified as “insufficiently active” (N = 50; Mage = 47.6 years), were extracted from 2 initial trials of a new cognitive-behavioral intervention. That treatment sought to improve self-regulation, mood, and self-efficacy through increased physical activity, to then induce improved eating …


Effect Of Activity Trackers And Text Messaging On Exercise, Fitness, And Physical Activity Self-Efficacy Of Middle School Students, Alison F. Pittman May 2017

Effect Of Activity Trackers And Text Messaging On Exercise, Fitness, And Physical Activity Self-Efficacy Of Middle School Students, Alison F. Pittman

Nursing Theses and Dissertations

A decrease in physical activity as children age is a contributing factor to the U.S. obesity epidemic. Middle school children are particularly vulnerable to sedentary activities. Activity trackers show promise as a means to motivate children and adults to increase physical activity (PA). This study examined the effect of a text messaging intervention and use of activity trackers with a companion social website on the body mass index (BMI), body fat percentage, physical fitness, and PA self-efficacy of middle school children. Children aged 11-14 (n=102) were randomly assigned to one of three groups for a 10-week intervention: activity tracker group; …

Modeling Bmi, Dietary Habits, And Physical Activity Among Ethnically Diverse Urban College Students, Hollie Jones, Nicholas Freudenberg, Lorraine Mongiello Jun 2015

Modeling Bmi, Dietary Habits, And Physical Activity Among Ethnically Diverse Urban College Students, Hollie Jones, Nicholas Freudenberg, Lorraine Mongiello

Journal of Health Disparities Research and Practice

Objectives The objective of this research study was to examine the relationship between BMI, physical activity, dietary habits, and student demographic factors (age, ethnicity, income, immigration, and sex). Given the association between overweight and obesity and the inequitable burden of chronic health conditions among ethnic minority populations, a deeper understanding of the socioeconomic, gender, age, and racial/ethnic variation in BMI, physical activity, and dietary habits is needed. The shifting demographics of urban college populations make urban college campuses an important setting for addressing the lifetime health needs of ethnically diverse urban populations.

Methods In this cross-sectional non-experimental study, we used …

Investigating The Value Of Workplace-Endorsed Social Media For Improving Deskbound Employee Physical Activity Program Engagement And Reducing Sedentary Behaviour Health Risks, Darren Leigh Webb

Theses: Doctorates and Masters

Sedentary (prolonged sitting) behaviour is now recognised as an independent health risk factor contributing to a number of preventable lifestyle related diseases (Katzmarzyk, Church, Craig, & Bouchard, 2009). The widespread integration of computers into the office environment has seen an increase in employee work time participating in technology facilitated desk-based tasks requiring them to remain physically inactive (Philipson & Posner, 2003). According to recent research, workplace sedentary behavioural practices have objectively been measured as accounting for 81.8% of employee time, with a further 15.3% categorised as light activity within office based populations (Parry & Straker, 2013). With a recorded national …

The Influence Of Preferred Attentional Focus Strategies On Exercise Induced Changes In Affect, Erin L. Heltsley Aug 2008

The Influence Of Preferred Attentional Focus Strategies On Exercise Induced Changes In Affect, Erin L. Heltsley

Masters Theses & Specialist Projects

Along with the numerous physical benefits of exercise, past research has shown that physical activity can alleviate symptoms of anxiety and depression in both clinical and non-clinical populations. Yet, it has been suggested less than half of American adults exercise at public health recommended levels. Therefore, it is important to identify factors that may lead to an increase in physical activity and, subsequently, improvements in mental health. Previous research, for the most part, has neglected to investigate how preference for attentional focus strategy during exercise influences mood. In addition, previous studies that involved attentional focus and exercise have focused more …
