Abstract

To determine how mental illness (MI) stigma messaging on Twitter manifests after a mass shooting, using the Fort Lauderdale Airport shooting (January 6, 2017) as a case study, we collected publicly available tweets about mental health/illness between December 23, 2016 and January 20, 2017 published from Florida (shooting location) and Virginia (comparison state; N = 38,634). We manually coded 3,283 tweets to build machine learning models to classify the remaining tweets by tweet topic and MI stigma messaging and assessed state-specific trends in these areas. We used logistic regression to determine which tweets were retweeted most frequently after the shooting. Violence-related MI stigma messaging increased sharply in both states (113% increase in Florida (9.8 percentage points)), 300% in Virginia (12 percentage points) following the shooting. Tweets containing violence-related MI stigma messaging also had increased odds of being retweeted. Violence-related MI stigma messaging on Twitter increased after the Fort Lauderdale shooting and transcended the geographic location of the shooting event. Violence-related MI stigma messaging also had increased odds of reaching a larger audience, suggesting widespread endorsement of this stigma. This demonstrates a need for advocacy for violence-related MI stigma reduction on social media following mass shootings.

Abstract

Abstract

Background: Research has identified cognitive behavioral therapy with exposures (CBT) as an effective treatment for youth anxiety. Despite implementation efforts, few anxious youth receive CBT. Direct-to-consumer marketing offers a different approach to address the unmet need for youth receiving effective treatments. Involving a local caregiver key opinion leader in direct-to-consumer initiatives may be an effective strategy to increase caregiver demand for CBT. Research indicates that key opinion leaders improve health promotion campaigns, but key opinion leaders have not been studied in the context of increasing caregiver demand for evidence-based treatments. Method: Project CHAT (Caregivers Hearing about Anxiety Treatments) will test the role of key opinion leader participation in conducting outreach presentations to increase caregiver desire to seek CBT for their youth’s anxiety. Caregiver attendees (N = 180) will be cluster randomized by school to receive one of two different approaches for presentations on CBT for youth anxiety. Both approaches will involve community outreach presentations providing information on recognizing youth anxiety, strategies caregivers can use to decrease youth anxiety, and how to seek CBT for youth anxiety. The researcher-only condition will be co-facilitated by two researchers. In the key opinion leader condition, a caregiver key opinion leader from each local community will be involved in tailoring the content of the presentation to the context of the community, co-facilitating the presentation with a researcher, and endorsing strategies in the presentation that they have found to be helpful. In line with the theory of planned behavior, caregiver attendees will complete measures assessing their knowledge of, attitudes towards, perceived subjective norms about, and intention to seek CBT pre- and post-presentation; they will indicate whether they sought CBT for their youth at 3-month follow-up. Results will be analyzed using a mixed method approach to assess the effectiveness of a key opinion leader to increase caregiver demand for CBT. Discussion: This study will be the first to examine the potential of key opinion leaders to increase caregiver demand for CBT. If proven effective, the use of key opinion leaders could serve as a scalable dissemination strategy to increase the reach of evidence-based treatments. Trial registration: This trial was registered on clinicaltrials.gov (NCT04929262) on June 18, 2021. At the time of trial registration, pre/post-presentation data had been collected from 17 participants; thus, it was retrospectively registered.

Abstract

Abstract

Background: Dissemination initiatives have the potential to increase consumer knowledge of and engagement with evidence-based treatments (e.g., cognitive behavioral therapy [CBT]). Opinion leaders (OLs) have been used in public health campaigns, but have not been examined for the dissemination of mental health treatments. This study uses the Theory of Planned Behavior to test the dissemination strategy of involving an OL in an educational presentation to increase caregiver demand for CBT for youth anxiety. Method: Participants (N = 262; 92% female; 69% White, 82% non-Hispanic) were caregivers who registered for a virtual presentation on youth anxiety treatment through their child's school. Schools within 1.5-hr drive of Philadelphia, PA were cluster-randomized (k = 25; two-arm prospective randomization) to the OL condition (presented by a clinical researcher and local caregiver OL; n = 119 participants) or the researcher-only condition (n = 143 participants). Presentations occurred from May 2021 to May 2022. Measures were completed pre- and post-presentation and at 3-month follow-up. Results: Relative to the researcher co-presenter, participants rated the OL as significantly more relatable, familiar, similar, and understanding of their community, but less credible than the researcher co-presenter. In both conditions, there was a significant pre-post increase in participants’ knowledge of, attitudes about, subjective norms related to, and intention of seeking CBT for youth anxiety, but not stigma. Presentation conditions did not differ in change on these measures, or on rates of seeking youth anxiety CBT at follow-up. Conclusions: Although involvement of a caregiver OL did not increase caregiver demand for evidence-based treatment for youth anxiety, the outreach presentation was associated with increases in knowledge of, attitudes about, subjective norms related to, and intention to seek CBT for youth anxiety. Involving OLs in researcher-delivered dissemination efforts may not be necessary for all consumer audiences, but may be beneficial for engendering a sense of relatability, similarity, and connection with disseminators.

Abstract

Abstract

Background: Marijuana decriminalization holds potential to reduce health inequities. However, limited attention has focused on assessing the impact of decriminalization policies across different populations. This study aims to determine the differential effect of a marijuana decriminalization policy change in Philadelphia, PA on marijuana arrests by demographic characteristics. Methods: Using a comparative interrupted time series design, we assessed whether the onset of marijuana decriminalization in Philadelphia County was associated with reduction in arrests rates from 2009 to 2018 compared to Dauphin County. Stratified models were used to describe the differential impact of decriminalization across different demographic populations. Results: Compared to Dauphin, the mean arrest rate for all marijuana-related crimes in Philadelphia declined by 19.9 per 100,000 residents (34.9% reduction), 17.1 per 100,000 residents (43.1% reduction) for possession, and 2.8 per 100,000 resident (15.9% reduction) for sales/manufacturing. Arrest rates also differed by demographic characteristics post-decriminalization. Notably, African Americans had a greater absolute/relative reduction in possession-based arrests than Whites. However, relative reductions for sales/manufacturing-based arrests was nearly 3 times lower for African Americans. Males had greater absolute/relative reduction for possession-based arrests, but lower relative reduction for sales/manufacturing-based arrests compared to females. There were no substantial absolute differences by age; however, youths (vs. adults) experienced higher relative reduction in arrest rates. Conclusions: Findings suggest an absolute/relative reduction for possession-based arrests post-decriminalization; however, relative disparities in sales/manufacturing-based arrests, specifically for African Americans, increased. More consideration towards the heterogeneous effect of marijuana decriminalization are needed given the unintended harmful effects of arrest on already vulnerable populations.

Abstract

Abstract

Context: Legal environments influence how health information technologies are implemented in public health practice settings. Syndromic disease surveillance (SyS) is a relatively new approach to surveillance that depends heavily on health information technologies to achieve rapid awareness of disease trends. Evidence suggests that legal concerns have impeded the optimization of SyS. Objectives: To (1) understand the legal environments in which SyS is implemented, (2) determine the perceived legal basis for SyS, and (3) identify perceived legal barriers and facilitators to SyS implementation. Design: Multisite case study in which 35 key informant interviews and 5 focus groups were conducted with 75 SyS stakeholders. Interviews and focus groups were audio recorded, transcribed, and analyzed by 3 coders using thematic content analysis. Legal documents were reviewed. Setting: Seven jurisdictions (5 states, 1 county, and 1 city) that were purposively selected on the basis of SyS capacity and legal environment. Participants: Health department directors, SyS system administrators, legal counsel, and hospital personnel. Results: Federal (eg, HIPAA) and state (eg, notifiable disease reporting) laws that authorize traditional public health surveillance were perceived as providing a legal basis for SyS. Financial incentives for hospitals to satisfy Meaningful Use regulations have eased concerns about the legality of SyS and increased the number of hospitals reporting SyS data. Legal issues were perceived as barriers to BioSense 2.0 (the federal SyS program) participation but were surmountable. Conclusion: Major legal reforms are not needed to promote more widespread use of SyS. The current legal environment is perceived by health department and hospital officials as providing a firm basis for SyS practice. This is a shift from how law was perceived when SyS adoption began and has policy implications because it indicates that major legal reforms are not needed to promote more widespread use of the technology. Beyond SyS, our study suggests that federal monetary incentives can ameliorate legal concerns regarding novel health information technologies.

Abstract

Objective: To study the impact of Medicaid funding structures before and after the implementation of the Affordable Care Act (ACA) on health care access for Latinos in New York (Medicaid expansion), Florida (Medicaid non-expansion), and Puerto Rico (Medicaid block grant). Data Sources: Pooled state-level data for New York, Florida, and Puerto Rico from the 2011–2019 Behavioral Risk Factor Surveillance System and data from the 2011–2019 American Community Survey and Puerto Rico Community Survey. Study Design: Cross-sectional study using probit with predicted margins to separately compare four health care access measures among Latinos in New York, Florida, and Puerto Rico (having health insurance coverage, having a personal doctor, delayed care due to cost, and having a routine checkup). We also used difference-in-differences to measure the probability percent change of having any health insurance and any public health insurance before (2011–2013) and after (2014–2019) the ACA implementation among citizen Latinos in low-income households. Data Collection: The sample consisted of Latinos aged 18–64 residing in New York, Florida, and Puerto Rico from 2011 to 2019. Principal Findings: Latinos in Florida had the lowest probability of having health care access across all four measures and all time periods compared with those in New York and Puerto Rico. While Latinos in Puerto Rico had greater overall health care access compared with Latinos in both states, health care access in Puerto Rico did not change over time. Among citizen Latinos in low-income households, New York had the greatest post-ACA probability of having any health insurance and any public health insurance, with a growing disparity with Puerto Rico (9.7% any [1.6 SE], 5.2% public [1.8 SE]). Conclusions: Limited Medicaid eligibility (non-expansion of Florida's Medicaid program) and capped Medicaid funds (Puerto Rico's Medicaid block grant) contributed to reduced health care access over time, particularly for citizen Latinos in low-income households.

Abstract

Abstract

For nonprofit hospitals to maintain their tax-exempt status, the Affordable Care Act requires them to conduct a community health needs assessment, in which they evaluate the health needs of the community they serve, and to create an implementation strategy, in which they propose ways to address these needs. We explored the extent to which nonprofit urban hospitals identified equity among the health needs of their communities and proposed health equity strategies to address this need. We conducted a content analysis of publicly available community health needs assessments and implementation strategies from 179 hospitals in twenty-eight US cities in the period August-December 2016. All of the needs assessments included at least one implicit health equity term (such as disparities, disadvantage, poor, or minorities), while 65 percent included at least one explicit health equity term (equity, health equity, inequity, or health inequity). Thirty-five percent of implementation strategies included one or more explicit health equity terms, but only 9 percent included an explicit activity to promote health equity. While needs assessment reporting requirements have the potential to encourage urban nonprofit hospitals to address health inequities in their communities, hospitals need incentives and additional capacity to invest in strategies that address the underlying structural social and economic conditions that cause health inequities.

Abstract

Introduction: Demonstrating the impact of implementation science presents a new frontier for the field, and operationalizing downstream impact is challenging. The Translational Science Benefits Model (TSBM) offers a new approach for assessing and demonstrating research impact. Here we describe integration of the TSBM into a mentored training network. Methods: Washington University’s Clinical and Translational Science Awards TSBM team collaborated with a National Institute of Mental Health-supported training program, the Implementation Research Institute (IRI), a 2-year training institute in mental health implementation science. This partnership included three phases: (1) introductory workshop on research impact, (2) workshop on demonstrating impact, and (3) sessions to guide dissemination, including interactive tools and consultation with the TSBM research team. Fifteen IRI alumni were invited to participate in the pilot; six responded agreeing to participate in the training, develop TSBM case studies, and provide feedback about their experiences. Participants applied the tools and gave feedback on design, usability, and content. We present their case studies and describe how the IRI used the results to incorporate TSBM into future trainings. Results: The case studies identified 40 benefits spanning all four TSBM domains, including 21 community, 11 policy, five economic, and three clinical benefits. Participants reported that TSBM training helped them develop a framework for talking about impact. Selecting benefits was challenging for early-stage projects, suggesting the importance of early training. Conclusions: The case studies showcased the institute’s impact and the fellows’ work and informed refinement of tools and methods for incorporating TSBM into future IRI training.

Abstract

Abstract

Among young people in the United States, nonfatal violent injuries outnumber fatal violent injuries by 171 to 1. The Child Fatality Review Team (CFRT) is a well-established model for informing injury prevention planning. The CFRT’s restricted focus on fatal injuries, however, limits its ability to identify opportunities to prevent violent reinjury and address issues unique to nonfatal violent injuries. We adapted the CFRT model to develop and implement a Youth Nonfatal Violent Injury Review Panel. We convened representatives from 23 agencies (e.g., police, housing, and education) quarterly to share administrative information and confidentially discuss cases of nonfatal violent injury. In this article, we describe the panel model and present preliminary data on participants’ perceptions of the process. Although outcomes research is needed to evaluate its impacts, the Youth Nonfatal Violent Injury Review Panel offers an innovative, promising, and replicable model for interagency collaboration to prevent youth violence and its effects.

Abstract

The public health impact of psychological science is maximized when it is disseminated clearly and compellingly to audiences who can act on it. Dissemination research can generate knowledge to help achieve this, but dissemination is understudied in the field of implementation science. As a consequence, the designs of dissemination strategies are typically driven by anecdote, not evidence, and are often ineffective. We address this issue by synthesizing key theory and findings from consumer psychology and detailing a novel research approach for “data-driven dissemination.” The approach has 3 parts: (a) formative audience research, which characterizes an audience’s awareness about, adoption of, and attitudes toward an intervention, as well as preferences for receiving information about it; (b) audience segmentation research, which identifies meaningful subgroups within an audience to inform the tailoring of dissemination strategies; and (c) dissemination effectiveness research, which determines the strategies that are most effective. This approach is then illustrated using the dissemination of the American Psychological Association’s (APA, 2017) Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder (PTSD) in Adults as a case study. Data are presented from a 2018–2019 survey of licensed APA-member psychologists who treat adults with PTSD (n = 407, response rate = 29.8%). We present survey findings on awareness about, attitudes toward, and adoption of the guideline and find significant differences across these domains between psychologists who do and do not regularly use clinical practice guidelines. We conclude by discussing future directions to advance dissemination research and practice.

Abstract

Youth violence is a significant US public health problem and a leading cause of adolescent morbidity and mortality.1 Homicide is the third leading cause of death among youth aged 10 to 24 years and has been the leading cause of death among black youth for well over a decade.2 Violently injured youth are at high risk for repeat injury; with recent data indicating that violent reinjury rates among urban youth treated in the emergency department (ED) are as high as 37%.3 Furthermore, these youth have high rates of involvement with severe and escalating forms of violence, with almost 60% reporting involvement with firearm violence as either a victim or aggressor within 2 years after receiving care for an assault injury.4

Abstract

Objectives. To examine trends and characteristics of proposed and enacted state legislation that would directly affect states’ immunization exemption laws. Methods. We performed content analysis of proposed bills in state legislatures from 2011 to 2017. We classified bills as provaccination or antivaccination. Results. State legislators proposed 175 bills, with the volume increasing over time: 92 (53%) bills expanded access to exemptions, and 83 (47%) limited the ability to exempt. Of the 13 bills signed into law, 12 (92%) limited the ability to exempt. Bills that expanded access to exemptions were more likely to come from Republican legislators and Northeastern and Southern states. Conclusions. Although most proposed legislation would have expanded access to exemptions, bills that limited exemptions were more likely to be enacted into law. Legal barriers to exempt one’s children from vaccination persist despite vaccine hesitancy, which is encouraging for public health. Public Health Implications. Most vaccine exemption laws introduced in state legislatures would pose threats to the public’s health. There is a need for constituents to engage their elected legislators and advocate provaccination policies.

Abstract

Abstract

Like many under resourced, island communities, most of the municipalities in Puerto Rico are medically underserved. However, there is limited information about changes in hospital capacity and any regional disparities in availability of hospital services in Puerto Rico, especially given the multiple public health emergencies the island has faced in recent years (e.g. hurricanes, earthquakes, and COVID-19). This study described the trends in hospital capacity and utilization for the Island of Puerto Rico and by health regions from 2010 to 2020. We analyzed the 2021–22 Area Health Resource File (AHRF) and aggregated the data by seven health regions, which are groupings of municipalities defined by the Puerto Rico Department of Health. Ten-year estimates for hospital utilization were adjusted for population size by health region. During the more recent five-year period, there were decreases in hospitals, hospital beds, and surgeries, which represent a shift from the earlier five-year period. Over the 10 years of the study period, there was an overall decrease in population-adjusted measures of hospital utilization on the island of Puerto Rico—despite multiple disasters that would, theoretically, increase need for health care services. We also found variation in hospital capacity and utilization by health regions indicating the rate of change was not uniform across Puerto Rico. The capacity of Puerto Rico’s hospital system has shrunk over the past decade which may pose a challenge when responding to recurrent major public health emergencies, especially within specific health regions.

Abstract

Objectives. To characterize US mayors’ and health commissioners’ opinions about health disparities in their cities and identify factors associated with these opinions. Methods. We conducted a multimodal survey of mayors and health commissioners in fall-winter 2016 (n = 535; response rate = 45.2%). We conducted bivariate analyses and multivariable logistic regression. Results. Forty-two percent of mayors and 61.1% of health commissioners strongly agreed that health disparities existed in their cities. Thirty percent of mayors and 8.0% of health commissioners believed that city policies could have little or no impact on disparities. Liberal respondents were more likely than were conservative respondents to strongly agree that disparities existed (mayors: odds ratio [OR] = 7.37; 95% confidence interval [CI] = 3.22, 16.84; health commissioners: OR = 5.09; 95% CI = 3.07, 8.46). In regression models, beliefs that disparities existed, were avoidable, and were unfair were independently associated with the belief that city policies could have a major impact on disparities. Conclusions. Many mayors, and some health commissioners, are unaware of the potential of city policies to reduce health disparities. Ideology is strongly associated with opinions about disparities among these city policymakers. Public Health Implications: Information about health disparities, and policy strategies to reduce them, needs to be more effectively communicated to city policymakers.

Abstract

Introduction Food systems can shape dietary behaviour and obesity outcomes in complex ways. Qualitative systems mapping using causal loop diagrams (CLDs) can depict how people understand the complex dynamics, inter-relationships and feedback characteristic of food systems in ways that can support policy planning and action. To date, there has been no attempt to review this literature. The objectives of this review are to scope the extent and nature of studies using qualitative systems mapping to facilitate the development of CLDs by stakeholders to understand food environments, including settings and populations represented, key findings and the methodological processes employed. It also seeks to identify gaps in knowledge and implications for policy and practice. Methods and analysis This protocol describes a scoping review guided by the Joanna Briggs Institute manual, the framework by Khalil and colleagues and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist reporting guidelines. A search strategy was iteratively developed with two academic librarians and the research team. This strategy will be used to search six databases, including Ovid MEDLINE, Embase, EmCare, Web of Science, Scopus and ProQuest Central. Identified citations will be screened by two independent reviewers; first, by title and abstract, and then full-text articles to identify papers eligible for inclusion. The reference lists of included studies and relevant systematic reviews will be searched to identify other papers eligible for inclusion. Two reviewers will extract information from all included studies and summarise the findings descriptively and numerically. Ethics and dissemination The scoping review will provide an overview of how CLDs developed by stakeholders have been elicited to understand food environments, diet and obesity, the insights gained and how the CLDs have been used. It will also highlight gaps in knowledge and implications for policy and practice. The review will be disseminated through publication in an academic journal and conference presentations.
