Thinking About Work At Home: Implications For Safety At Work, Frankie Guros
Thinking About Work At Home: Implications For Safety At Work, Frankie Guros
Dissertations and Theses
Safety at work is of the utmost importance to employees and the organizations they work for, and as such, it is a central issue for occupational health psychology. Although dramatic decreases in the number of worker injuries and fatalities have been observed over the last several decades, safety remains a principal concern for organizations. This is especially true in occupations in which employees face serious threats to their personal safety, such as correctional officers (COs). While a number of studies have identified workplace factors that contribute to worker safety, few have attempted to draw a link between employee nonwork experiences …

Background: Particulate matter ≤ 2.5 μm in aerodynamic diameter (PM2.5) has been consistently associated with preterm birth (PTB) to varying degrees, but roles of PM2.5 species have been less studied.
Objective: We estimated risk differences (RD) of PTB (reported per 106 pregnancies) associated with change in ambient concentrations of elemental carbon (EC), organic carbon (OC), nitrates (NO3), and sulfates (SO4).
Methods: From live birth certificates from three states, we constructed a cohort of singleton pregnancies at or beyond 20 weeks of gestation from 2000 through 2005 (n = 1,771,225; 8% PTB). We estimated mean species exposures for each week of …
Social Norms About A Health Issue In Work Group Networks, Lauren B. Frank
Social Norms About A Health Issue In Work Group Networks, Lauren B. Frank
Communication Faculty Publications and Presentations
The purpose of this study is to advance theorizing about how small groups understand health issues through the use of social network analysis. To achieve this goal, an adapted cognitive social structure examines group social norms around a specific health issue, H1N1 flu prevention. As predicted, individual’s attitudes, self-efficacy, and perceived social norms were each positively associated with behavioral intentions for at least one of the H1N1 health behaviors studied. Moreover, collective norms of the whole group were also associated with behavioral intentions, even after controlling for how individual group members perceive those norms. For members of work groups in …
Non-Steroidal Anti-Inflammatory Drug Use In Collegiate Athletes, Brian Robert Davis
Non-Steroidal Anti-Inflammatory Drug Use In Collegiate Athletes, Brian Robert Davis
Dissertations and Theses
Non-steroidal anti-inflammatory drugs (NSAID) are a class of medications used in the treatment of pain, inflammation, and illness. These medications are common, affordable, and easy to access. For these reasons, NSAIDs are commonly used by athletes of all backgrounds for treating injuries and as ergogenic aids. However, despite these behaviors, NSAIDs have well-documented side effects and the efficacious nature of these medications has been brought into question. Despite this, many athletes continue to use these medications frequently and indiscriminately. It is not known why athletes use these medications in light of their questionable effectiveness and cited adverse effects. Therefore, this …

Background—Fewer than half of all U.S. adults meet the 2008 Physical Activity Guidelines. Leader behaviors and group cohesion have been associated with increased participation or adherence in sports team and exercise class settings. Physical activity interventions in community settings that encompass these factors may enhance intervention adherence.
Purpose—To examine the impact of Community Health Promoter leader behaviors and group cohesion on participation in a walking group intervention among racially/ethnically diverse adults in low-to-moderate income communities in Detroit, Mich.
Design—Data for the current study were drawn from the Walk Your Heart to Health (WYHH) data set. WYHH was a multi-site cluster …

Background—Other than Kaposi's sarcoma (KS)-associated herpesvirus and CD4+ T cell lymphopenia, the mechanisms responsible for KS in the context of HIV are poorly understood. One recently explored pathway of HIV pathogenesis involves induction of the enzyme indoleamine 2,3 dioxygenase-1 (IDO), which catabolizes tryptophan into kynurenine and several other immunologically active metabolites that suppress T cell proliferation. We investigated the role of IDO in the development of KS in HIV disease.
Methods—In a case-control study among untreated HIV-infected Ugandans, cases were adults with KS and controls were without KS. IDO activity was assessed by the ratio of plasma kynurenine to tryptophan …

Background: People with developmental disabilities (DD) are often not included as participants in research owing to a variety of ethical and practical challenges. One major challenge is that traditional measurement instruments may not be accessible to people with DD. Participatory research approaches promise to increase the participation of marginalized communities in research, but few partnerships have successfully used such approaches to conduct quantitative studies people with DD.
Objective: To use a community-based participatory research (CBPR) approach to create an accessible, computer-assisted survey about violence and health in people with DD, and to psychometrically test adapted health instruments.

Background: Up to 50 % of HIV-infected persons in sub-Saharan Africa are lost from care between HIV diagnosis and antiretroviral therapy (ART) initiation. Structural barriers, including cost of transportation to clinic and poor communication systems, are major contributors.
Methods: We conducted a prospective, pragmatic, before-and-after clinical trial to evaluate a combination mobile health and transportation reimbursement intervention to improve care at a publicly operated HIV clinic in Uganda. Patients undergoing CD4 count testing were enrolled, and clinicians selected a result threshold that would prompt early return for ART initiation or further care. Participants enrolled in the pre-intervention period (January – …

Background: Many environmental factors have been independently associated with preterm birth (PTB). However, exposure is not isolated to a single environmental factor, but rather to many positive and negative factors that co-occur. The environmental quality index (EQI), a measure of cumulative environmental exposure across all US counties from 2000—2005, was used to investigate associations between ambient environment and PTB.
Methods: With 2000–2005 birth data from the National Center for Health Statistics for the United States (n = 24,483,348), we estimated the association between increasing quintiles of the EQI and county-level and individual-level PTB; we also considered environmental domain-specific (air, …

Objective—Regular HIV RNA testing for all HIV positive patients on antiretroviral therapy (ART) is expensive and has low yield since most tests are undetectable. Selective testing of those at higher risk of failure may improve efficiency. We investigated whether a novel analysis of adherence data could correctly classify virological failure and potentially inform a selective testing strategy.
Design—Multisite prospective cohort consortium.
Methods—We evaluated longitudinal data on 1478 adult patients treated with ART and monitored using the Medication Event Monitoring System (MEMS) in 16 United States cohorts contributing to the MACH14 consortium. Since the relationship between adherence and virological failure is …

Objective—To assess the role of sexual relationships on levels and patterns of adherence to medication for pre-exposure prophylaxis (PrEP) against HIV.
Methods—We enrolled 1,147 HIV-negative individuals in long-term serodiscordant relationships at three sites in Uganda from the Partners PrEP Study- a randomized placebo-controlled trial of daily oral tenofovir and emtricitabine/tenofovir. We used generalized estimation equations to assess the effects of sexual relationships on low adherence (
Results—Fifty-three percent were male, 51% were 18-34 years and 24% were polygamous. Participants who reported sex in the past month with someone other than their primary partner and with
Conclusions—Risk of low overall adherence …
Whom Do You Trust? Doubt And Conspiracy Theories In The 2009 Influenza Pandemic, Shawn Smallman
Whom Do You Trust? Doubt And Conspiracy Theories In The 2009 Influenza Pandemic, Shawn Smallman
International & Global Studies Faculty Publications and Presentations
The 2009 pandemic of H1N1 influenza led people around the globe to create narratives about the epidemic defined by the question of trust; these narratives ranged from true conspiracy theories to simply accounts in which mistrust and betrayal formed a motif. In particular, most of these narratives reflected a fear of capitalism and globalization, although in specific regions, other issues—such as religion—played a more central role. These stories were not unique to the H1N1 pandemic but rather have appeared with every contemporary outbreak of infectious disease. This paper will examine conspiracy theories and moral panics related to the H1N1 pandemic …

Malaria is a leading cause of pediatric mortality, and Uganda has among the highest incidences in the world. Increased morbidity and mortality are associated with delays to care. This qualitative study sought to characterize barriers to prompt allopathic care for children hospitalized with severe malaria in the endemic region of southwestern Uganda. Minimally structured, qualitative interviews were conducted with guardians of children admitted to a regional hospital with severe malaria. Using an inductive and content analytic approach, transcripts were analyzed to identify and define categories that explain delayed care. These categories represented two broad themes: sociocultural and structural factors. Sociocultural …

Client self-reports (3-day, 30-day, Case Index ≥48 consecutive hours of missed ART), healthcare provider estimates and the pharmacy medication possession ratio (MPR) were used to estimate ART adherence. Participants from two facilities per country underwent HIV RNA testing. Optimal adherence measures were selected on the basis of degree of association …
Analytic Thinking Predicts Vaccine Endorsement: Linking Cognitive Style And Affective Orientation Toward Childhood Vaccination, Daniel A. Anderson
Analytic Thinking Predicts Vaccine Endorsement: Linking Cognitive Style And Affective Orientation Toward Childhood Vaccination, Daniel A. Anderson
University Honors Theses
Though popular opinion in the US is favorable toward vaccination, a growing hesitancy to vaccinate children threatens rates of uptake and coverage. In response, researchers now study psychological factors thought to influence vaccine-decisions, as having this information might be useful in addressing vaccine hesitancy in the clinic and beyond. The present thesis reviews evidence from this body of work, and shares results of a new study on the influence of analytic and intuitive thinking styles upon endorsement of childhood vaccines. In a national sample (N = 543), analytic thinking predicted endorsement alone and in the presence of covariates in …
