Item Preventing Drowsy Driving in Young Adults Through Messaging Strategies that Influence Perceptions of Control and Risk(2024) Lee, Clark Johnson; Butler III, James; Beck, Kenneth H; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Drowsy driving is a serious health and safety problem in the United States: thousands of car crashes on U.S. roadways each year are attributed to this risky driving behavior. Although young drivers under the age of 26 years are especially at risk for being involved in drowsy driving car crashes, few anti-drowsy driving interventions targeting such drivers have been developed. Furthermore, most existing educational materials and interventions against drowsy driving have focused primarily on providing factual information about the dangers of drowsy driving and countermeasures against these dangers rather than on influencing beliefs and motivations underlying drowsy driving behavior, which may explain their apparent ineffectiveness at preventing drowsy driving behavior and resultant car crashes. Recent research indicates that messages targeting perceptions of control may be effective intervention strategies against drowsy driving behavior for young adult drivers by influencing their drowsy driving-related perceptions of risk, intentions, and willingness. This dissertation continues this line of research by pursuing two lines of inquiry. In Study #1, the efficacy of anti-drowsy driving messaging strategies designed to influence perceptions of control and risk related to drowsy driving behavior in reducing drowsy driving intentions, willingness, and behavior in a sample of young adult U.S. drivers between 18 and 25 years of age was evaluated through a randomized controlled trial. Study #1 sought to test the following hypotheses: Hypothesis 1: Participants exposed to interventional messaging strategies primarily aimed at lowering perceptions of control or heightening perceptions of risk related to drowsy driving report significantly less perceived control, greater perceived risk, less intentions, less willingness, and less behavior related to drowsy driving at 30-day post-intervention follow-up compared to participants exposed to messaging strategies providing only factual information about the dangers of drowsy driving; and Hypothesis 2: Participants exposed to interventional messaging strategies aimed at both lowering perceptions of control and heightening perceptions of risk related to drowsy driving report significantly less perceived control, greater perceived risk, less intentions, less willingness, and less behavior related to drowsy driving at 30-day post-intervention follow-up compared to participants exposed to messaging strategies providing only factual information about the dangers of drowsy driving, messaging strategies primarily aimed at lowering perceptions of control related to drowsy driving, or messaging strategies primarily aimed at heightening perceptions of risk related to drowsy driving. In Study #2, the relationships between perceived behavioral control, risk perception, intentions, willingness, and drowsy driving behavior in a sample of young adult U.S. drivers between 18 and 25 years of age were examined. Study #2 sought to test the following hypotheses: Hypothesis 3: The impact of interventional messaging strategies targeting drowsy driving perception of control on drowsy driving intentions, willingness, and behavior is mediated by drowsy driving risk perception such that messages lowering drowsy driving perceptions of control also heighten drowsy driving risk perception, which in turn decreases drowsy driving intentions, willingness, and behavior; Hypothesis 4: Interventional messaging strategies targeting drowsy driving-related perceptions of control or risk have a greater impact on drowsy driving willingness than on drowsy driving intentions; and Hypothesis 5: Drowsy driving willingness is a stronger predictor of drowsy driving behavior than is drowsy driving intentions. Study #1 provided supporting evidence of short-term cognitive effects but not short-term behavioral effects after exposure to messaging interventions designed to influence perceptions of control and risk related to drowsy driving behavior. Perceptions of risk were especially influenced by the messaging strategies examined, including those that provided only factual, knowledge-based information about drowsy driving. Study #2 provided supporting evidence that perceived behavioral control influenced drowsy driving intentions and drowsy driving willingness indirectly through perceptions of risk. Furthermore, willingness to drive drowsy was a stronger predictor of actual drowsy driving behavior than intentions to drive drowsy. The findings from these two studies should inform future research aimed at developing more effective messaging strategies against drowsy driving behavior in young adults.Item COLLABORATIVE CO-DESIGN OF PORTABLE WORK BENEFITS POLICY MODEL AND NON-POLICY PROTOTYPE BASED ON DIRECT CARE WORKERS' NEEDS, ATTITUDES, AND BELIEFS(2024) Kuo, Charlene C.; Aparicio, Elizabeth M.; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Direct care workers (DCWs) assist people with disabilities and frail elders with activities of daily living, thereby preventing institutionalization, hospitalization, and other costly medical services. From 2016 to 2060, the number of adults aged 65 and over is expected to increase from 49.2 million to 94.7 million. The number of adults 18 to 64 will remain the same, leading to a shortage of family caregivers. A shortage of family caregivers will require a robust direct care workforce. The direct care workforce is expected to grow by 1.3 million from 2019 to 2029 but this growth will not keep pace with the projected demand. The turnover rate among DCWs is high due to poor work conditions and inadequate compensation. Exploring ways to improve DCW working conditions and compensation is critical to prevent further shortages. DCWs' health is put at risk due to the nature of the work, low wages, and lack of worker protections and traditional work benefits. DCWs are vulnerable to injury, abuse, infectious diseases, and other poor health outcomes due to the previously listed disadvantages (Campbell, 2019c; Hughes, 2020; Jaffe, 2017; M. M. Quinn et al., 2016). DCWs in the United States are predominantly women, members of racial and ethnic minority groups, and one in four workers are immigrants.Work benefits improve health outcomes and protect clients of DCWs from healthcare-associated infections by allowing DCWs to take paid sick leave when ill. Portable benefits are benefits employees can take from job to job, prorated so that multiple employers can contribute, and accessible to all workers. Portable benefits are not widely available. I held 1)individual in-depth interviews and focus groups to explore the needs, attitudes, and beliefs of DCWs regarding work benefits, 2) two co-design sessions and a member checking session with DCWs to develop and refine policy recommendations for Maryland DCWs' portable work benefits, and 3) a co-design session and member checking sessions to develop usability recommendations for websites delivering portable benefits to DCWs. This study provides findings about direct care workers' experiences with inadequate or nonexistent work benefits, their recommendations for policy to support benefits that meet their needs and preferences, and their usability recommendations for portable benefits websites. This study provides information on how to design work benefits for DCWs that protect them, protect those around them, and improve work conditions in hopes of improving work conditions and compensation.Item The Critical Race Framework Study: Standardizing Critical Evaluation for Research Studies That Use Racial Taxonomy(2024) Williams, Christopher M.; Fryer, Craig S.; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Introduction: Race is one of the most common variables in public health surveillance and research. Yet, studies involving racial measures show poor conceptual clarity and inconsistent operational definitions. There does not exist a bias tool in the public health literature for structured qualitative evaluation in critical areas of critical appraisal – reliability, validity, internal validity, and external validity – for studies that use racial taxonomy. This study developed the Critical Race (CR) Framework to address a major gap in the literature. Methods: The study involved three iterative phases to answer five research questions (RQs). Phase I was a pilot study of the CR Framework among public health faculty and doctoral students to assess measures of fit (RQ1) and to identify areas of improvement in training, instrumentation, and study design (RQ2). Study participants received training and performed a single article evaluation. Phase II was a national cross-sectional study of public health experts to assess perceptions of the revised training and tool to assess measures of fit (RQ1), to determine the influence of demographic and research factors on perceptions (RQ3), and to gather validity evidence on constructs (RQ4). In Phase III, three raters performed article evaluations to support reliability evidence (RQ4) and to determine the quality of health disparities and behavioral health research studies against the CR Framework (RQ5). Analysis: We assessed the reliability of study results and the CR Framework using non-differentiation analysis, thematic analysis, missingness analysis, user data, measures of internal consistency for adopted instruments, interrater agreement, and interrater reliability. Validity was assessed using content validity (CVI and k*), construct validity, and exploratory factor analyses (EFA). Results: The study recruited 30 highly skilled public health experts across its three phases as part of the final analytic sample. Phase I had poor reliability in which the results could not be confidently interpreted (RQ1) and indicated needed improvement in study design, training, and instrumentation (RQ2). Based on Phase II results, we met or exceeded acceptable thresholds for measures of fit – acceptability, appropriateness, feasibility, and satisfaction (RQ1). Demographic or research factors were not associated with responses (RQ3). Interrater agreement was moderate to high among rater pairs (RQ4). Due to lack of confidence in significance testing, interrater reliability results were inconclusive. Overall data results showed excellent content validity. Based on EFA results, construct validity for reliability and validity items was poor to fair (RQ4). Data results were inconclusive on internal validity and external validity. The twenty studies used in critical appraisal showed low quality or no discussion when the Critical Race Framework was used (RQ5). Discussion: The CR Framework study developed a tool and training with quality evidence for implementation effectiveness, content validity, and interrater reliability to fill a major gap in the public health literature. It contributed an innovative theory-based tool and training to the literature. Future research should seek to study individual perceptions and practices that influence outcomes of CR Framework application and to reduce barriers to ensure that minimum sample sizes can be met for additional testing.Item Exploring Young Bi+ Women's Intersecting Mental Health and Sexual and Reproductive Health Experiences in Context: A Multi-Analytic Method Qualitative Study(2023) Robinson, Jennifer Lynn; Aparicio, Elizabeth M; Butler, James; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Young bi+ women report worse mental health and sexual and reproductive health (SRH) outcomes compared to gay, lesbian, and straight young adults. They experience intersecting threats to their health and well-being due to their sexuality, gender, and stage of development. There is a lack of research on bi+ women’s unique mental health and SRH experiences, and often bi+ women are overlooked due to bi-erasure and biphobia. Regressive policies related to LGBTQ+ and women’s rights, including increased restrictions to reproductive healthcare after the Dobbs v. Jackson Women’s Health Organization decision overturning abortion protections, further threaten bisexual women’s health. This dissertation used a multi-analytic method qualitative approach to explore the intersecting mental health and SRH experiences of young bisexual women in the current socio-political context. Semi-structured in-depth interviews were conducted over Zoom with 16 young bi+ women from across the U.S. A narrative inquiry approach was used to explore young bi+ women’s mental health experiences and coping strategies. In addition, thematic analysis was used to investigate how young bi+ women describe their mental health as intersecting with their SRH in the current socio-political context. The study yielded rich and nuanced information about challenges these young bi+ women experienced throughout their lives that affected their mental health and SRH. Experiencing trauma had far-reaching negative effects on their mental health. Participants discussed the challenges of forming their identity within the social context, particularly as bi+ women in a society that often invalidates bisexual identities and subjugates women. They also discussed the joys along with difficulties of navigating young adulthood. They further described coping with challenges in a variety of adaptive (e.g., therapy, exercise) and maladaptive (e.g., substance use, self-injury) ways. They discussed relying on social support such as partners, friends, family, therapists, and teachers. Participants desired more support with sexuality-related issues, particularly in early adolescence. These bi+ women described their mental health and SRH as intertwined and discussed how bodily autonomy and agency were essential to their well-being. The socio-political context, including social norms, rhetoric, and federal- and state-level policies, influenced participants’ well-being. The current study shows that young bi+ women face unique threats to their mental health and SRH. Practice implications include improving access to affordable and LGBTQ+-affirming healthcare and developing interventions attuned to the needs of young bi+ women. Policies are needed that uphold the choice and agency of young women in their reproductive health decision-making. Future research should continue to explore the needs and experiences of young bi+ women concerning their mental health and SRH including demographic differences along with potential mechanisms resulting in poorer health.Item A NATIONAL SURVEY EVALUATING FACTORS INFLUENCING AMERICANS’ WILLINGNESS TO USE AND UPTAKE OF EMERGENCY CONTRACEPTIVE PILLS(2022) Jasczynski, Michelle; Aparicio, Elizabeth M; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)In the United States, a paradox exists around the issue of contraception; there are more highly effective contraceptive methods available than ever before, including emergency contraception, yet unintended pregnancies have increased in the last 2 decades. Currently, 1 in 2 pregnancies in the United States are unplanned. These disparities are not equitably distributed among women of reproductive age and people who can become pregnant; the burden disproportionately falls upon those with limited access to healthcare, people of color, gender and sexual minorities, those with lower socioeconomic status, and people living in the South. Recognizing the multiple factors driving decisions made about contraception, evaluation of the underutilization and other potential barriers to emergency contraceptive pills (ECP) can be in part addressed by the completion of a national survey. Most of the existing survey data for the United States provide insight into the perceptions of pharmacists, healthcare providers in emergency rooms, and college-aged women. A survey capturing the needs and experiences of a wider range of Americans has not yet been developed—most notably the need for a survey that is inclusive of an expansive understanding of gender identity and sexual orientation to evaluate what, if any, differences exist in how members of these groups view and choose to use ECPs. A web survey was completed in March 2022. Two groups of participants were recruited simultaneously: a group of cisgender, heterosexual women (n = 351), and a group of cisgender sexual minority women and gender minorities assigned female at birth (n = 408), for a total of 759 participants. Comparisons between cisgender heterosexual participants and cisgender sexual minority participants were completed using chi-squared tests and t tests to determine if there were differences in willingness to use and uptake of ECPs by sexual orientation. Latent class analysis (LCA) was completed to identify subgroups among the respondents. The latent class model was then used to determine if membership in the three latent classes predicted willingness to use ECPs and the number of times ECPs were used. Differences between classes on these two outcomes of interest were compared using chi-squared tests. Among each group, approximately 1 in 3 respondents had used ECPs at least once. Cisgender sexual minority participants had a higher willingness to use ECPs when compared to cisgender heterosexual participants (F[2, 708] = 16.33, p < .001). Cisgender sexual minority participants who used ECPs previously also were found to be less willing to reuse ECPs again when compared to their cisgender, heterosexual counterparts (χ2 [2] = 5.14, p = .023), with the most common reason of not wanting to use ECPs again due to participants indicating they would desire to be pregnant. The LCA final model had three classes: high reproductive coercion/low stigma (Class 1), low reproductive coercion/low stigma (Class 2), and low reproductive coercion/high stigma (Class 3). When regressed on the number of times ECPs were used, the three-class model was found to be statistically significant for the overall model (χ2 = 28.95, p < .001). Class 3 (low reproductive coercion, high stigma) was significantly different from Class 1 and Class 2 when comparing the mean number of times ECPs had been used, with members of Class 3 averaging using ECPs 1.56 times versus Class 1 and Class 2 both averaging .56 times use (p < .001). The high levels in which sexual minority women were willing to use ECPs but were less likely to reuse them again should be explored more in depth to understand underlying factors in decision making around contraceptive uptake and pregnancy intentions. The desire to become pregnant is the most common reason given for why sexual minority women would not use ECPs, highlighting the need for healthcare providers to have regular conversations with their patients about sexual behavior, contraceptive use, and pregnancy intentions. Individuals experiencing higher levels of stigma toward their use of ECPs have a higher prevalence of use. Although the direction of this association is yet to be determined, further investigation of this phenomenon can inform practice and policy to understand the impact of stigma and promote reproductive justice.Item STATE-LEVEL STRUCTURAL RACISM AND ALCOHOL AND TOBACCO USE BEHAVIORS IN A NATIONAL PROBABILITY SAMPLE OF AFRICAN AMERICANS(2023) Woodard, Nathaniel; Knott, Cheryl L; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Structural racism is how society maintains and promotes racial discrimination through established and interconnected systems. Structural racism is a historical driver of health disparities, including those in the area of cancer. One pathway posited for this effect is through the promotion of maladaptive coping behaviors, such as alcohol and tobacco use. This dissertation empirically assessed the association between state-level structural racism and alcohol and tobacco use behaviors among African Americans, including within various subgroups of African Americans based on age, gender, and household income. This project analyzed secondary self-report data collected from a national probability sample of 1,946 African Americans in the Religion and Health in African Americans (RHIAA) Study. Existing measures of state level structural racism were merged into the RHIAA dataset including a composite index of structural racism assessed using five dimensions (i.e., residential segregation, and economic, employment, education, and incarceration disparities). Analyses were performed in SPSS Version 28 using hierarchical linear and logistic regression models. In the first study, two models (Model A and Model B) were constructed for each of four outcomes, frequency of alcohol consumption (measured in days per month), frequency of binge drinking (measured in the number of occurrences per month), smoking status (current smoker or not a current smoker), and smoking frequency (never smoked, former smoker, currently smoke on some days, and currently smoke every day). Model A used the composite structural racism index measure to model the four alcohol and tobacco use measures and Model B analyzed the disaggregated dimensions of structural racism rather than the composite measure. All hierarchical analyses controlled for confounding variables (i.e., participant gender, age, education, income, and employment status). In the second study, analyses using the dimension-level approach in Model B from study one were repeated in subgroups stratified by participant age, gender, and income for the frequency of binge drinking and smoking status behaviors. Statistical comparisons of the slope estimates between corresponding subgroups (e.g., younger and older age) were used to test the moderation effects of age, gender, and income on the association between structural racism and alcohol and tobacco use behaviors. Results from these studies generally indicated a positive association between state level structural racism, especially in the incarceration dimension, and binge drinking and tobacco use behaviors. Stratified analyses generally did not support age, gender, or income as moderating variables of the association between structural racism and binge drinking and tobacco use behaviors. Current findings demonstrate a need for further research on structural racism and health and progress in structural racism measurement, including further emphasis of dimension-level measurement and analysis. Findings from the current dissertation highlight the importance of addressing structural racism, especially in incarceration, to reduce alcohol and tobacco use behaviors among African Americans and help address existing health disparities.Item EXAMINING THE IMPACT OF PRECONCEPTION AND EARLY PREGNANCY SERUM LEVELS OF MATERNAL VITAMIN D ON CLINICAL MARKERS OF IMPLANTATION AND PREECLAMPSIA(2023) Alkhalaf, Zeina; Thoma, Marie; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Vitamin D is a hormone rather than a vitamin, that is essential for overall health and wellbeing, including but not limited to the reproductive system. Although vitamin D is available through several sources, such as natural ultraviolet sunlight, food, and supplements, low circulating 25-hydroxyvitamin D (25(OH)D) levels of <30 ng/mL are common among pregnant women, with up to 69% of the US population suffering from the condition. Epidemiologic studies have suggested that low maternal serum 25(OH)D levels may be associated with adverse pregnancy outcomes, such as early pregnancy loss and preeclampsia, which may be initiated early in the pregnancy process during implantation and placentation. From a life course perspective, the periconception and early pregnancy period marks a critical time for establishing a healthy pregnancy. Implantation and placentation occur early in pregnancy and involve a complex process that relies on optimal endometrial receptivity and a host of hormonal and immunologic signaling events. Disruptions to this process may be indicated by early clinical markers of pregnancy complications (e.g., vaginal bleeding or subchorionic hemorrhage) and associated with later adverse outcomes (e.g., preeclampsia). In contrast, higher Human Chorionic Gonadotropin (hCG) levels, which have been linked to nausea and vomiting, may be markers of robust implantation and placentation. Therefore, I sought to investigate the preconception and early gestation maternal serum 25(OH)D levels on: (i) vaginal bleeding and subchorionic hemorrhage; (ii) nausea and vomiting; (iii) preeclampsia. In Aim 1, an analysis of medical record documentation of vaginal bleeding and subchorionic hemorrhage found that women who were persistently deficient/insufficient in maternal serum 25(OH)D at both preconception and 8-week gestation had 2.18 times higher (95% CI: 1.13, 4.20) odds of having subchorionic hemorrhage compared to women who remained sufficient across both time periods, even after adjustment for potential confounders. Additionally, an analysis of daily diaries showed women with deficient 25(OH)D levels had a higher odds (OR: 3.02, 95% CI: 1.13, 8.13) of moderate/heavy bleeding versus none compared to women with sufficient 25(OH)D levels based on self-reported daily diaries on vaginal bleeding at the start of pregnancy. In Aim 2, women with persistently deficient 25(OH)D levels at both preconception and early gestation had lower odds (OR: 0.34, 95% CI: 0.20, 0.60) of experiencing nausea and vomiting based on medical records. In comparison, women who increased their 25(OH)D levels early in pregnancy (i.e., were deficient/insufficient at preconception then became sufficient at 8-week gestation) had 1.71 (95% CI: 1.12, 2.61) times higher odds of nausea and vomiting compared to those who were persistently sufficient across both time periods. Based on self-reported nausea and vomiting symptoms from daily diaries, deficient 25(O)D was associated with lower odds (OR 0.65; 95% CI 0.40, 1.06) of both nausea and vomiting when comparing to sufficient 25(OH)D levels. In Aim 3, women who had deficient 25(OH)D at preconception had an increased risk (RR: 1.45, 95% CI: 0.64, 3.29) of preeclampsia (as identified from medical records), although results were insignificant. Linear spline models demonstrated that the risk of preeclampsia declined with each 1 ng/mL increase of 25(OH)D levels up to 40-45 ng/mL (RR: 0.97, 95% CI: (0.93, 1.00), but that levels beyond this threshold show an increase in the risk of preeclampsia for each 1 ng/mL increase in 25(OH)D (RR: 1.03; 95% CI: 1.00, 1.06). This research highlights the importance of exploring the maternal serum levels of 25(OH)D at both preconception and early gestation and how it may affect adverse pregnancy outcomes, such as vaginal bleeding, subchorionic hemorrhage, preeclampsia, and pregnancy outcomes that signify a robust implantation response, such as nausea and or vomiting. It further underscores the importance of assessing maternal serum 25(OH)D levels prior to critical time of implantation and placentation and potential biologic mechanisms that may lead to adverse pregnancy outcomes. Supporting healthy implantation and placentation is of utmost importance as this may guide the remainder of the health of the pregnancy, and any disruption to this process may increase the mother and infant’s risk of maternal morbidity and mortality (e.g., preeclampsia, vaginal bleeding, subchorionic hemorrhage). Future studies are needed with more diverse, larger sample sizes, and both paternal and maternal nutrition to further assess preconception nutritional risk factors on adverse and robust pregnancy outcomes. Accordingly, this research is vital as it may aid in identifying early factors that may reduce adverse maternal and infant health outcomes.Item ADAPTING A BREAST CANCER CONTROL INTERVENTION FOR AFRICAN AMERICAN WOMEN BELOW SCREENING AGE: A CO-DESIGN APPROACH(2023) Huq, Maisha R; Knott, Cheryl L; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Background: Despite African American women below screening age facing greater mortality from early onset breast cancer relative to similar aged peers of other races/ethnicities and African American women of screening age, little attention is given to this group of younger women. Evidence-based breast cancer educational interventions do not exist for this group of younger women. The purpose of the current work was to address the gap of evidence-based breast cancer educational interventions for African American women below screening age. Aims: The current study had two aims. Aim 1 was to adapt an evidence-based breast cancer educational intervention for African American women of screening age, to be targeted to younger African American women (i.e. those below screening age) using a systematic process guided by the seven-step adaptation framework by Card and colleagues, documented using an established implementation science model, the Framework for Reporting Adaptations and Modifications Enhanced Model (FRAME), and using a virtual co-design approach. Aim 2 was to assess the appropriateness of the adapted intervention for African American women below screening age through online surveys administered at the conclusion of Community Chat sessions. Methods: The adaptation process was guided by Card and colleagues’ seven-step framework. Five virtual co-design sessions with n=15 potential users and key stakeholders were conducted in step 7. Observational notes and FRAME Form data were collected from the co-design sessions and analyzed using five-step thematic and descriptive statistics analyses, respectively. Appropriateness data was collected through an online survey; quantitative data were analyzed using descriptive statistics and open-text survey responses were analyzed using five-step thematic analysis. Results: Application of Card and colleagues’ seven step framework was described. Six themes emerged from observing virtual co-design sessions: technological tools can encourage equal participation; personal relationships and stories enhance design; participants introduced content to promote equity; context of original intervention critical to adapt; challenges to virtual designing; and need for facilitator during co-design. Documentation of the adaptation process guided by FRAME found 14 adaptations led to “Black and Breasted (B&B)”, an Instagram and beauty brand partnership-based breast health education tool prototype. Motivations for adaptations were to promote fit (100%), reach (71%), and equity (29%). Adaptations were content (63%) and context-related (37%). All participants rated B&B as highly appropriate—selecting an average of 4.5 (SD=1.4) and 1.2 (SD=.75) reasons, respectively, B&B would and would not be a good fit. Thematic analysis of open-text responses on how to further enhance B&B identified four themes: increase strategies to improve health equity, use multiple social media, consider non-beauty brands, revise visuals/messages. Conclusions & Implications: While usage of the implementation science models led to a highly appropriate adapted intervention, initial testing identified the need for further strategies to improve equity of health outcomes through the intervention. Findings indicate implementation science frameworks may benefit from centering equity more. Co-design may also be an apt approach to promote health equity in public health interventions.Item Exploring the Politics and Radical Health Activism Strategies of Black-Led Grassroots Organizations in Washington, D.C.(2023) Fox, Imani; Simon-Rusinowitz, Lori; White, Kellee; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Black communities in Washington, DC have long experienced health inequities due to a history of inequitable social policies and inadequate access to health-related resources (Jackson, 2017). Critical, academic scholars and social justice activists implicate the political economy and racial oppression as a root cause of health inequities in the country. Black grassroots organizations demonstrate a history of political and social resistance to oppressive health and social systems, defending their right to health and autonomy, known as radical health activism (Nelson, 2011). Despite rich accounts of Black-led health interventions, their contributions to public health practice and frameworks have not been widely reviewed in public health discourse. Using informant interviews and descriptive study analysis, the health politics and subsequent health intervention strategies of Black grassroots organizations in Washington, D.C were examined. The 3 core themes that emerged from this study were health politics, radical health intervention strategies, and successes and challenges.Item "Alexa, do I have an STD?": An Exploration of Young Adult Information Seeking Behaviors When Engaging With Home Assistant Devices About Sexually Transmitted Infections(2023) Siddiqui, Junaed Ahmad; Baur, Cynthia; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)BACKGROUND: Sexually transmitted diseases and infections continue to disproportionately affect young adults in the United States, with half of all new STIs annually occurring in young adults between the ages of 15 and 24. Advances in digital technologies have allowed for the facilitation of fast and discreet information about sexual health but remains understudied in the context of newer technologies. There is limited research on the effectiveness of Home Assistant Devices as channels to facilitate the information seeking process in young adults. To address this gap, this study explored whether Home Assistant Devices can facilitate the sexual health information seeking process in young adults between the ages of 18 and 26 who already use the internet to search for health information. The purpose of this dissertation was to explore the perspectives of young adults to understand the depth of their sexual health information needs and whether a user-centric designed HAD can be a suitable alternative for fulfilling those information needs. METHODS: Informed by the Theory of Motivated Information Management and Technology Acceptance Model, this qualitative study used the Design Thinking framework to understand young adults’ information needs and created a prototype voice skill to address that need. In-depth interviews were conducted virtually on Google Meet or Zoom and were recorded. This qualitative study occurred in three phases: in the first phase, 10 young adults were interviewed about their information seeking needs, current gaps, and how they thought Home Assistant Devices could fill that need. Insights from those interviews were then analyzed and used to create a prototype that would address sexual health information needs. The prototype was then tested with a new group of ten young adults, and their reactions to the prototype was recorded via interviews. In the third phase, the prototype was refined based on feedback from the previous group, and then re-tested with a new group of 10 young adults. In total, in depth interviews were conducted virtually with 30 young adults to understand information needs and create a prototype voice skill that could serve to facilitate the transfer of sexual health information in a convenient and relevant manner. Inductive thematic analysis was conducted to identify emergent themes. RESULTS: Overall, the sample (n=30) was 63% female, 43% White, with 53% having completed a bachelor’s degree, and 47% having owned a Home Assistant Device for over 12 months. The average age of the sample was 24 years old. After analyzing interviews through inductive thematic analysis in NVivo, four themes that were noted in the first phase as it related to Home Assistant Devices and information needs: the use of HADs as a means of convenience, preferring to use screen-based devices for research, tradeoffs between privacy and functionality, and the ability to emergency triage users for medical attention based on symptoms. Three main themes emerged in the second phase after reacting to the first version of the prototype, including anxiety and frustration when experiencing the unknown, pre-existing positive perceptions of Home Assistant Devices, and negative perceptions of Home Assistant Devices. In the third phase, two main themes emerged: a desire to share visuals to build comfort and bridge the information gap, and an ambivalence towards privacy. DISCUSSION: Privacy concerns remain prominent with Home Assistant Devices when engaging with them for information seeking purposes. These concerns are sometimes met with ambivalence by young adults, who were willing to trade some of their privacy for added features or functionality that could improve their user experience. Furthermore, challenges remain with voice search and screen-based devices are perceived to be easier to use. Lastly, the sexual health information seeking process is sensitive, and many young adults in this sample expressed wanting to have a more personalized experience that acknowledged their specific situations. To the author’s knowledge, this is the first study that explored the factors contributing to the sexual health information seeking process using Home Assistant Devices among young adults between the ages of 18 and 26. The results of this study have several implications for public health practice and research, especially as it relates to the Design Thinking approach for public health voice skill development, as well as addressing a new approach to providing sexual health information to young adults that may be more discreet and relevant to them. The findings from this study contribute to the emerging literature base on the use of Home Assistant Devices to address sensitive health information seeking behaviors.
