    Effect of Program Implementation Fidelity on Outcomes of the Lifestyle Change Program Conducted through Distance Learning by Cooperative Extension
    Pourkhalili, Azin Rose (Virginia Tech, 2023-07-03)
    The National Diabetes Prevention Program (National DPP) was established by Congress in 2010, with a focus on disseminating the evidence-based Lifestyle Change Program (LCP). This 12-month program consists of 26 lessons covering various topics related to goal setting, tracking food and physical activity, motivation, and support groups. Many organizations, including Cooperative Extension (CE), have adopted this program. In the first study conducted by the Virginia Cooperative Extension (VCE), the outcomes of the prediabetes LCP were examined across different age groups and delivery modalities. It was found that distance learning LCPs had slightly higher enrollment levels compared to in-person programs (51% vs. 49%). Moreover, participants aged 60 and older had a significantly higher attendance rate in the distance learning program. The VCE LCP resulted in 49 participants (35%) achieving at least a 5% weight loss, with 29 of them being 60 years or older. When considering the program delivery method, a higher percentage of individuals enrolled in distance learning programs (53%) achieved at least a 5% weight loss. Additionally, 86 participants (62%) engaged in an average of 150 minutes of physical activity per week, with a higher percentage in the in-person programs (64%) and among those aged 60 and older (67%). In Study 2, the distance learning LCP implementation fidelity was evaluated across five states, along with its association with program outcomes. The evaluation tool assessed structural and instructional implementation components. The results indicated that certain structural components directly influenced increased physical activity among participants. Additionally, the coaches' preparedness for the sessions directly impacted participants' weight loss. In addition to implementation fidelity, age was identified as an independent factor affecting weight loss percentage and attendance. Overall, the findings from both studies underscore the significance of effective implementation fidelity to program design in achieving desired health outcomes. The LCP shows promise as an intervention for individuals at risk of developing type 2 diabetes and can be effectively implemented through both in-person and distance learning methods by Cooperative Extension programs nationwide.

    Examining Contributors and Solutions to Prevent and Manage Food Waste in Households with Low Incomes and the Emergency Food System within the U.S.
    Chen, Susan (Virginia Tech, 2021-08-25)
    In the United States (U.S.), up to 40% of the entire food supply is lost or wasted, which contributes to negative environmental, economic, and social outcomes, with the majority of food waste occurring in the retail and consumer sectors of the food supply chain. Concurrently, 10.5% of U.S. households experienced food insecurity in 2019. Food insecurity rates are higher among individuals with low income and disproportionately affects ethically and racially diverse people living in poverty. Diverting excess food from retail and institutional settings to people in need is one method to reduce food waste and enhance individual, household, and community food security. This PhD dissertation describes four studies that explored food waste management in the U.S. among households with low-income and within U.S. food pantries, which are a critical component of the emergency food system. Study 1 consisted of a systematic review that examined differences in food waste attitudes and practices among consumers of across income levels. Study 2 was a quantitative research methods approach to examine food waste attitudes and practices of SNAP-eligible households (n=17). Study 3 was a cross-sectional quantitative approach to examine the impact of the novel coronavirus disease (COVID-19) pandemic on food waste management within U.S. food pantries (n=290). Study 4 assessed the feasibility of food pantries in Virginia (n=68) to implement marketing-mix and choice-architecture (MMCA) strategies within their food pantries given the changes they had to make in their food distribution models in response to COVID-19 physical distancing requirements. Collectively, the studies described in this PhD dissertation address knowledge gaps and may be used to inform policies and initiatives to increase food security and decrease food waste among households with low-income and organizations aimed at serving them.

    Green Roof Exposure and Office Workers' Mental Health: Work-related Distress, Mental Fatigue, and Perceived Restoration
    Ozturk Sari, Sevda (Virginia Tech, 2023-02-14)
    More than half of the world's population works full time and spends about one-third of their weekdays at workplaces (International Labor Organization, 2022). Mental disorders are one of the health problems that have emerged among working populations (World Health Organization, 2022). Previous empirical research and theories demonstrated that nature exposure positively impacts human health and wellbeing (Kaplan and Kaplan 1989). Green roofs can be one of the most easily accessible nature places for office workers in city centers. This study examines the relationship between green roofs and work-related distress, mental fatigue, and restoration. An online survey of 179 employees was used to evaluate the relationship between exposure to six different green roofs and employee work-related distress, mental fatigue, and mental restoration. The results show that the average time spent on green roofs and the frequency of visits have statistically significant relationships with the mental restoration.

    Narrative Persuasion and Transportation Theory as a Stigma Reduction Method for Substance Use Disorder: A Thematic Analysis
    Maher, Emily Therese (Virginia Tech, 2022-04-15)
    Drug use, overdose, and addiction has skyrocketed in the past twenty years (Centers for Disease Control and Prevention, 2020). Negative stigma towards addiction, or otherwise known as substance use disorder (SUD), has only increased since President Nixon declared the "war on drugs" in 1971 (National Public Radio, 2007). Negative public stigma of SUD creates barriers for treatment for those who are suffering, continuing to exacerbate the stigma surrounding SUD. To understand ways to reduce stigma surrounding SUD, this study will look at narrative persuasion through transportation theory to better understand the power of stories and stories of recovery as a method to reduce stigma surrounding SUD among community members. In addition to examining narrative persuasion literature, 21 semi-structured interviews from community stakeholder groups in Virginia's Department of Behavioral Health and Developmental Services region 3, were conducted. To further understand the content in the stakeholder interviews, a qualitative thematic analysis using inductive themes was conducted to determine common themes surrounding substance use disorder, stigma, and ways to reduce stigma surrounding substance use disorder through narrative persuasion. Based on participant interviews, community stakeholders hold negative perceptions of those with SUD based on personal and professional experiences but believe that positive personal narratives of SUD and recovery can reduce public stigma towards those who suffer from the disorder.
