Unintended consequences of disseminating behavioral health evidence to policymakers: Results from a survey-based experiment.

Background: Communication research demonstrates that messages often have unintended consequences, but this work has received limited attention in implementation science. This dissemination experiment sought to determine whether state-tailored policy briefs about the behavioral health consequences of adverse childhood experiences (ACEs), compared to national policy briefs on the topic, increased state legislators'/staffers' perceptions of the policy brief relevance and parental blame for the consequences of ACEs, and whether effects differed between Democrats and Republicans. Method: A preregistered, web-based survey experiment with U.S. state legislators/staffers was conducted in 2021 (n = 133). Respondents were randomized to view a policy brief about the behavioral health consequences of ACEs that included state-tailored data (intervention condition) or national data (control condition) and then answered survey questions. Dependent variables were perceived policy brief relevance and parental blame for the consequences of ACEs. Results: The mean policy brief relevance score was 4.1% higher in the intervention than in the control condition (p = .24), but the mean parental blame score was 16.5% higher (p = .02). When outcomes were dichotomized, 61.2% of respondents in the intervention condition rated parents as "very much to blame" for the consequences of ACEs compared to 37.1% in the control condition (p = .01). When the sample was stratified by political affiliation, the effect of the state-tailored policy brief on parental blame was larger in magnitude among Democrats and not significant among Republicans. The intervention policy brief increased the mean parental blame score by 22.8% among Democrats relative to the control policy brief (p = .007) and doubled the proportion rating parents as "very much to blame" (52.2% vs. 26.1%, p = .03). Conclusions: Despite limited statistical power, state-tailored policy briefs significantly increased state legislators'/staffers' perceptions of parental blame for the behavioral health consequences of ACEs, relative to a policy brief with national data. Unintended messaging effects warrant greater attention in dissemination research and practice.

Prior studies have tested the effects of dissemination strategies on policymakers' engagement with research evidence. However, little research has assessed the potential unintended consequences of disseminating evidence to policymakers. This knowledge gap is important because a large body of communication research has found that messages often have negative and unintended effects. This paper adds to the literature on disseminating evidence about behavioral health issues to policymakers. A web-based survey experiment was conducted in which U.S. state legislators/staffers were randomized to view a policy brief about adverse childhood experiences (ACEs) that was tailored to present data from their state (intervention condition) or a policy brief that presented national data and then completed a survey. Legislators/staffers who viewed the state-tailored policy brief perceived the brief as slightly more relevant, but also rated parents as being significantly more to blame for the behavioral health consequence of ACEs. The effect of the state-tailored policy brief on parental blame is an unintended messaging effect that signals cause for caution when disseminating evidence about ACEs to policymakers and other practice audiences. More broadly, the findings highlight a need to consider unintended messaging effects in dissemination research and practice.

Newspaper Coverage of Adverse Childhood Experiences and Toxic Stress in the United States, 2014-2020: Consequences, Causes, and Solutions.

News media can shape public opinion about child adversity and influence the translation of research into public policy. Research about adverse childhood experiences (ACEs) and toxic stress has increased dramatically in recent years, but little is known about how these concepts are covered in news media. We reviewed how newspapers in the United States have portrayed the consequences of, causes of, and solutions to address ACEs and toxic stress, examined trends in newspaper coverage, and assessed differences in coverage of ACEs versus toxic stress. Quantitative content analysis was conducted of 746 newspaper articles mentioning "adverse childhood experience(s)" and/or "toxic stress" published in 25 U.S. newspapers between January 1, 2014, and May 30, 2020. κ statistics of interrater reliability were calculated, and variables with κ ≥ .60 were retained for quantitative analysis. We found that newspaper coverage of ACEs and toxic stress increased dramatically between 2014 and 2018 and then sharply declined. Only 13.3% of articles mentioned both ACEs and toxic stress. There were many statistically significant (p < .05) differences in the causes, consequences, and solutions identified in articles focused on ACEs versus toxic stress. Coverage of both concepts predominantly focused on consequences for individuals, not society. However, 54.6% of articles identified a structural cause of ACEs and/or toxic stress. Increased volume in newspaper coverage about ACEs and toxic stress could increase public awareness about the relationship between childhood adversity and adult outcomes. There is a need to portray ACEs and toxic stress as complementary concepts more coherently in news media.

Partisan differences in the effects of economic evidence and local data on legislator engagement with dissemination materials about behavioral health: a dissemination trial.

BACKGROUND: State legislators make policy decisions that influence children's exposure to adverse childhood experiences (ACEs), such as child maltreatment, and their effects on behavioral health. Effective dissemination of scientific research can increase the likelihood that legislators' decisions are aligned with evidence to prevent ACEs and their consequences, and effective dissemination requires legislators to engage with dissemination materials. Informed by the elaboration likelihood model of persuasive communication and Brownson's Model of Dissemination Research, we tested the hypothesis that inclusion of economic evidence and local data would increase legislator engagement with dissemination materials about evidence-supported policies related to ACEs and behavioral health. METHODS: A three-arm randomized dissemination trial was conducted. A university researcher e-mailed dissemination materials which contained evidence about ACEs and behavioral health problems to state legislators (two e-mails sent 2 weeks apart, 12,662 e-mails delivered to 6509 legislators). The e-mail subject lines, text, and policy brief content were manipulated across the study arms. The intervention condition received state-tailored data about rates of ACEs and state-tailored economic evidence about the costs of ACEs for public systems, the enhanced control condition received state-tailored data and not economic evidence, and the control condition received national data and not economic evidence. Outcomes were rates of e-mail views, policy brief link clicks, requests for researcher consultation, and mentions of child maltreatment terms in legislators' social media posts. RESULTS: For the first e-mail, the e-mail view rate was 42.6% higher in the intervention than in the enhanced control condition (22.8% vs. 14.8%) and 20.8% higher than in the control condition (22.8% vs. 18.5%) (both p < .0001). Similar results were observed for the second e-mail. These differences remained significant after adjustment for demographic differences across study conditions in individual-level models, but not multilevel models. There was a significant interaction between the experimental condition and political party (p < .0001) in which the intervention increased e-mail view rates among Democrats but not Republicans. The intervention had no effect on policy brief link clicks or requests for consultation and a mixed effect on social media posts. CONCLUSIONS: Inclusion of state-tailored economic evidence in dissemination materials can increase engagement with research evidence among Democrat, but not Republican, legislators. Dissemination strategies tailored for legislators' political party affiliation may be needed.

State Policies that Impact the Design of Children's Mental Health Services: A Modified Delphi Study.

To identify the state-level policies and policy domains that state policymakers and advocates perceive as most important for positively impacting the use of children's mental health services (CMHS). We used a modified Delphi technique (i.e., two rounds of questionnaires and an interview) during Spring 2021 to elicit perceptions among state mental health agency officials and advocates (n = 28) from twelve states on state policies that impact the use of CMHS. Participants rated a list of pre-specified policies on a 7-point Likert scale (1 = not important, 7 = extremely important) in the following policy domains: insurance coverage and limits, mental health services, school and social. Participants added nine policies to the initial list of 24 policies. The "school" policy domain was perceived as the most important, while the "social" policy domain was perceived as the least important after the first questionnaire and the second most important policy domain after the second questionnaire. The individual policies perceived as most important were school-based mental health services, state mental health parity, and Medicaid reimbursement rates. Key stakeholders in CMHS should leverage this group of policies to understand the current policy landscape in their state and to identify gaps in policy domains and potential policy opportunities to create a more comprehensive system to address children's mental health from a holistic, evidence-based policymaking perspective.

Simulating the role of knowledge brokers in policy making in state agencies: An agent-based model.

OBJECTIVE: To model children's mental health policy making dynamics and simulate the impacts of knowledge broker interventions. DATA SOURCES: Primary data from surveys (n = 221) and interviews (n = 64) conducted in 2019-2021 with mental health agency (MHA) officials in state agencies. STUDY DESIGN: A prototype agent-based model (ABM) was developed using the PARTE (Properties, Actions, Rules, Time, Environment) framework and informed through primary data collection. In each simulation, a policy is randomly generated (salience weights: cost, contextual alignment, and strength of evidence) and discussed among agents. Agents are MHA officials and heterogenous in their properties (policy making power and network influence) and policy preferences (based on salience weights). Knowledge broker interventions add agents to the MHA social network who primarily focus on the policy's research evidence. DATA COLLECTION/EXTRACTION METHODS: A sequential explanatory mixed method approach was used. Descriptive and regression analyses were used for the survey data and directed content analysis was used to code interview data. Triangulated results informed ABM development. In the ABM, policy makers with various degrees of decision influence interact in a scale-free network before and after knowledge broker interventions. Over time, each decides to support or oppose a policy proposal based on policy salience weights and their own properties and interactions. The main outcome is an agency-level decision based on policy maker support. Each intervention and baseline simulation runs 250 times across 50 timesteps. PRINCIPAL FINDINGS: Surveys and interviews revealed that barriers to research use could be addressed by knowledge brokers. Simulations indicated that policy decision outcomes varied by policy making context within agencies. CONCLUSIONS: This is the first application of ABM to evidence-informed mental health policy making. Results suggest that the presence of knowledge brokers can: (1) influence consensus formation in MHAs, (2) accelerate policy decisions, and (3) increase the likelihood of evidence-informed policy adoption.

Inter-agency collaboration is associated with increased frequency of research use in children's mental health policy making.

OBJECTIVE: To determine whether the self-report frequency of inter-agency collaboration about children's mental health issues is associated with the self-report frequency of using research evidence in children's mental health policy and program decision making in mental health agencies (MHAs). DATA SOURCES: Primary data were collected through web-based surveys of state (N = 221) and county (N = 117) MHA officials. DESIGN: The primary independent variable was a composite score quantifying the frequency of collaboration about children's mental health issues between officials in MHAs and six other state agencies. The dependent variables were composite scores quantifying the frequency of research use in children's mental health policy and program decision making in general and for specific purposes (i.e., conceptual, instrumental, tactical, imposed). Covariates were composite scores quantifying well-established determinants of research use (e.g., agency leadership, research use skills) in agency policy and program decision making. DATA METHODS: Separate multiple linear regression models estimated associations between frequency of inter-agency collaboration and research use scores, adjusting for other determinants of research use, respondent state, and other covariates. Data from state and county officials were analyzed separately. PRINCIPAL FINDINGS: The frequency of inter-agency collaboration was positively and independently associated with the frequency of research use in children's mental health policy making among state (ß = 0.22, p = 0.004) and county (ß = 0.39, p < 0.0001) MHA officials. Inter-agency collaboration was also the only variable significantly associated with the frequency of research use for all four specific purposes among state MHA officials, and similar findings we observed among county MHA officials. The magnitudes of associations between inter-agency collaboration and frequency of research use were generally stronger than for more well-established determinants of research use in policy making. CONCLUSIONS: Strategies that promote collaboration between MHA officials and external agencies could increase the use of research evidence in children's mental health policy and program decision making in MHAs.

Review: Structural Racism, Children's Mental Health Service Systems, and Recommendations for Policy and Practice Change.

OBJECTIVE: Racism is a public health crisis that impacts on children's mental health, yet mental health service systems are insufficiently focused on addressing racism. Moreover, a focus on interpersonal racism and on individual coping with the impacts of racism has been prioritized over addressing structural racism at the level of the service system and associated institutions. In this paper, we examine strategies to address structural racism via policies affecting children's mental health services. METHOD: First, we identify and analyze federal and state policies focused on racism and mental health equity. Second, we evaluate areas of focus in these policies and discuss the evidence base informing their implementation. Finally, we provide recommendations for what states, counties, cities, and mental health systems can do to promote antiracist evidence-based practices in children's mental health. RESULTS: Our analysis highlights gaps and opportunities in the evidence base for policy implementation strategies, including the following: mental health services for youth of color, interventions addressing interpersonal racism and bias in the mental health service system, interventions addressing structural racism, changes to provider licensure and license renewal, and development of the community health workforce. CONCLUSION: Recommendations are provided both within and across systems to catalyze broader systems transformation.

Policy Makers' Priorities for Addressing Youth Substance Use and Factors That Influence Priorities.

OBJECTIVE: Understanding public policy makers' priorities for addressing youth substance use and the factors that influence these priorities can inform the dissemination and implementation of strategies that promote evidence-based decision making. This study characterized the priorities of policy makers in substance use agencies of U.S. states and counties for addressing youth substance use, the factors that influenced these priorities, and the differences in priorities and influences between state and county policy makers. METHODS: In 2020, a total of 122 substance use agency policy makers from 35 states completed a Web-based survey (response rate=22%). Respondents rated the priority of 14 issues related to youth substance use and the extent to which nine factors influenced these priorities. Data were analyzed as dichotomous and continuous variables and for state and county policy makers together and separately. RESULTS: The highest priorities for youth substance use were social determinants of substance use (87%), adverse childhood experiences and childhood trauma (85%), and increasing access to school-based substance use programs (82%). The lowest priorities were increasing access to naloxone for youths (49%), increasing access to medications for opioid use disorder among youths (49%), and deimplementing non-evidence-based youth substance use programs (41%). The factors that most influenced priorities were budget issues (80%) and state legislature (69%), federal (67%), and governor priorities (65%). Issues related to program implementation and deimplementation were significantly higher priorities for state than for county policy makers. CONCLUSIONS: These findings can inform the tailoring of dissemination and implementation strategies to account for the inner- and outer-setting contexts of substance use agencies.

Public Opinion About Adverse Childhood Experiences: Social Stigma, Attribution of Blame, and Government Intervention.

Adverse childhood experiences (ACEs) are receiving increasing attention in academic, policy, and media discourses. However, no public opinion research has focused on ACEs. We conducted a nationally representative survey of U.S. adults to address this knowledge gap. A web-based survey was conducted using the Ipsos KnowledgePanel (N = 503, completion rate = 60.5%) in fall 2019. We found that inter-personal stigma and parental blame related to ACEs were prevalent, with 25.0% of respondents unwilling to have a person with "a lot of ACEs" as a close co-worker and 65.2% believing that parents were very much to blame for the consequences of ACEs. Fifty percent of respondents believed that government intervention to prevent ACEs was very important. After adjustment for demographic characteristics, inter-personal stigma toward people with ACEs and conservative ideology were significantly associated with lower perceived importance of government intervention to prevent ACEs. Black race, Hispanic ethnicity, and female gender were significantly associated with higher perceived importance of government intervention. These findings provide an empirical foundation to inform strategies to communicate ACE science to public and policymaker audiences.

Impacts of COVID-19 on Mental Health Safety Net Services for Youths: A National Survey of Agency Officials.

OBJECTIVE: Mental health agencies provide critical safety net services for youths. No research has assessed impacts of the COVID-19 pandemic on services these agencies provide or youths they serve. This study sought to characterize agency officials' perceptions of the pandemic's impacts on youths and challenges to providing youth services during the pandemic and to examine associations between these challenges and impacts. METHODS: Surveys were completed in September-October 2020 by 159 state or county mental health agency officials from 46 states. Respondents used 7-point scales (higher rating indicated more severe impact or challenge) to rate the pandemic's impact on youth mental health issues, general service challenges, and telepsychiatry service challenges across patient, provider, and financing domains. Multiple linear regression models estimated associations between service challenges (independent variables) and pandemic impacts (dependent variables). RESULTS: Most agency officials perceived the pandemic as having disproportionately negative mental health impacts on socially disadvantaged youths (serious impact, 72%; mean rating=5.85). Only 15% (mean=4.29) perceived the pandemic as having a seriously negative impact on receipt of needed youth services. Serious service challenges were related to youths' lack of reliable equipment or Internet access for telepsychiatry services (serious challenge, 59%; mean=5.47) and the inability to provide some services remotely (serious challenge, 42%, mean=4.72). In regression models, the inability to provide some services remotely was significantly (p≤0.01) associated with three of five pandemic impacts. CONCLUSIONS: Officials perceived the COVID-19 pandemic as exacerbating youth mental health disparities but as not having a dramatic impact on receipt of needed services.

Selecting evidence to frame the consequences of adverse childhood experiences: testing effects on public support for policy action, multi-sector responsibility, and stigma.

While clinical and public health researchers have produced a high volume of research evidence about the consequences of ACEs, there is limited research on public understanding of ACEs or how to most effectively communicate about this body of science. The objective of this study was to determine which messages describing evidence about the consequences of adverse childhood experiences (ACEs) affect public perceptions. We conducted an online experiment with a nationally-representative sample of U.S. adults in July-August 2020. Participants were randomized to control groups receiving messages describing ACE prevalence or resilience, or treatment groups receiving messages describing consequences of ACEs on mental health and substance use, economics, racial equity, or biology. We compared respondents' perceptions of prevention policies and likelihood of policy engagement, attributions of multi-sector responsibility, and blame and stigma across experimental groups. Messages about economic consequences increased respondents' support for policy and attributions of multi-sector responsibility relative to control groups, while also increasing parental blame. The message describing racial equity lowered respondents' perceptions of importance of state policy action and attributions of responsibility to health care. None of the messages affected stigmatizing attitudes. Describing the economic consequences of ACEs on public systems boosts public support for policy action. More research is needed on how the public responds to messaging connecting systemic racism with childhood adversity and health.

Academic-Policy Partnerships in Evidence-Based Practice Implementation and Policy Maker Use of Child Mental Health Research.

OBJECTIVE: Strategies are needed to improve policy makers' evidence-informed decision making and the availability of evidence-based, state-supported services. This study examined whether academic-policy partnerships could promote these outcomes. METHODS: Data from two national surveys of state mental health agency representatives were used to compare barriers to implementation of evidence-based practices (EBPs) and policy makers' use of child mental health research in states with strong academic-policy partnerships in workforce training or in program implementation/evaluation (IE) with barriers in states with no or limited partnerships in these areas. RESULTS: Strong IE partnerships were associated with more confidence in research use and fewer issues with provider readiness and capacity but with more issues with EBP fidelity. Strong training partnerships were associated with fewer endorsements of lack of time as a barrier to research use. CONCLUSIONS: Academic-policy partnerships had some benefit for states' research use and EBP implementation. Because these partnerships may reduce barriers, further research should explore characteristics of effective collaborations.

Determinants of using children's mental health research in policymaking: variation by type of research use and phase of policy process.

BACKGROUND: Research use in policymaking is multi-faceted and has been the focus of extensive study. However, virtually no quantitative studies have examined whether the determinants of research use vary according to the type of research use or phase of policy process. Understanding such variation is important for selecting the targets of implementation strategies that aim to increase the frequency of research use in policymaking. METHODS: A web-based survey of US state agency officials involved with children's mental health policymaking was conducted between December 2019 and February 2020 (n = 224, response rate = 33.7%, 49 states responding (98%), median respondents per state = 4). The dependent variables were composite scores of the frequency of using children's mental health research in general, specific types of research use (i.e., conceptual, instrumental, tactical, imposed), and during different phases of the policy process (i.e., agenda setting, policy development, policy implementation). The independent variables were four composite scores of determinants of research use: agency leadership for research use, agency barriers to research use, research use skills, and dissemination barriers (e.g., lack of actionable messages/recommendations in research summaries, lack of interaction/collaboration with researchers). Separate multiple linear regression models estimated associations between determinant and frequency of research use scores. RESULTS: Determinants of research use varied significantly by type of research use and phase of policy process. For example, agency leadership for research use was the only determinant significantly associated with imposed research use (ß = 0.31, p < 0.001). Skills for research use were the only determinant associated with tactical research use (ß = 0.17, p = 0.03) and were only associated with research use in the agenda-setting phase (ß = 0.16, p = 0.04). Dissemination barriers were the most universal determinants of research use, as they were significantly and inversely associated with frequency of conceptual (ß = -0.21, p = 0.01) and instrumental (ß = -0.22, p = 0.01) research use and during all three phases of policy process. CONCLUSIONS: Decisions about the determinants to target with policy-focused implementation strategies-and the strategies that are selected to affect these targets-should reflect the specific types of research use that these strategies aim to influence.

Perceived Persuasiveness of Evidence About Adverse Childhood Experiences: Results From a National Survey.

OBJECTIVE: Advocates must make decisions about the types of evidence they emphasize when communicating to cultivate support for adverse childhood experience (ACE) prevention policies. This study sought to characterize public perceptions of the persuasiveness of 12 ACE evidence statements and assess differences by ideology in the strength of these evidence messages as rationales for ACE prevention policies. METHODS: A web-based survey of a nationally representative sample of US adults was conducted using the KnowledgePanel (N = 503, completion rate = 60.5%). Respondents read ACE evidence statements and answered questions about the extent to which each was perceived as persuasive. Data were collected and analyzed in 2019. RESULTS: The evidence statements perceived as most persuasive (scoring range 3-17) were those about ACEs as risk factors for mental health and substance use conditions (mean = 12.39) and suicide (mean = 12.14); ACEs generating financial costs for society (mean = 12.03); and the consequences of ACEs being preventable by a supportive adult (mean = 11.97). The evidence statements perceived as least persuasive were about ACEs generating health care costs for individuals (mean = 9.42) and ACEs as risk factors for physical health conditions (mean = 9.47). A larger proportion of liberals than conservatives rated every statement as providing a "strong reason" for ACE prevention policies. These differences were largest for evidence about ACEs generating financial costs for society (84.6% vs 42.8%, P < .0001) and socioeconomic disparities in ACEs (65.1% vs 32.9%, P < .0001). CONCLUSIONS: Many ACE evidence statements commonly used in policy advocacy differ from those perceived as most persuasive among a nationally representative sample of US adults.

Trends Over a Decade in NIH Funding for Autism Spectrum Disorder Services Research.

Investments in autism spectrum disorder (ASD) research, guided by the Interagency Autism Coordinating Committee (IACC), have focused disproportionately on etiology over a well-established stakeholder priority area: research to improve accessibility and quality of community-based services. This study analyzed National Institutes of Health ASD services research funding from 2008 to 2018 to examine funding patterns, evaluate the impact of IACC objectives, and identify future directions. Approximately 9% of total funds were allocated to services research. This investment remained relatively stable across time and lacked diversity across domains (e.g., area of focus, ages sampled, implementation strategies used). While advancements were observed, including increased prevalence of projects focused on adult samples and on dissemination/implementation and prevention areas, greater investment in service research is critically needed.

Associations Between Cross-Sector Partnerships and Local Health Department Participation in Population-Based Activities to Prevent Mental Health Conditions.

Objectives. To describe partnerships between US local health departments (LHDs) and community organizations and assess the relationship between the types of activities performed in these partnerships and LHD engagement in population-based activities to prevent mental health conditions.Methods. Data were derived from 457 LHDs that responded to module 1 of the 2016 Profile Study conducted by the National Association of County and City Health Officials. These data were used to assess the presence of partnerships with community organizations and examine associations between the types of activities performed in such partnerships and LHDs' participation in population-based activities to prevent mental health conditions.Results. LHDs had higher odds of participating in population-based activities to prevent mental health conditions if they shared personnel or resources or had written agreements with mental health or substance use disorder providers, held regularly scheduled meetings with hospitals, or shared personnel or resources with community health centers. Odds were reduced if they exchanged information with community health centers or shared personnel or resources with faith-based organizations.Conclusions. This study offers an improved understanding of how the types of activities performed in cross-sector partnerships affect LHDs' participation in population-based activities to prevent mental health conditions, which is important as public policies, programs, and funding initiatives continue to encourage cross-sector partnership building.

Dissemination Strategies to Accelerate the Policy Impact of Children's Mental Health Services Research.

The United States is in the midst of a children's mental health crisis, with rates of depression, anxiety, and suicide increasing precipitously. Evidence produced by children's mental health services research can help address this crisis by informing public policy decisions about service delivery, system design, and investments in the social determinants of mental health. Unfortunately, the policy impact of children's mental health services research is limited because evidence often fails to reach policy makers, be responsive to their needs, resonate with their worldview, or reflect the contexts in which they make decisions. Dissemination strategies-defined as the development and targeted distribution of messages and materials about research evidence pertaining to a specific issue or intervention-can help address these challenges. Yet, limited integrated guidance exists to inform the design of such strategies. This article addresses this need by synthesizing the results of empirical studies to provide guidance about how to enhance the dissemination of children's mental health services research to policy makers. The article provides four recommendations about the content of policy maker-focused dissemination materials, discusses how strategic framing and message tailoring can increase the chances that evidence is persuasive to policy makers, and highlights strategies to ensure that evidence reaches policy makers.

Factors associated with state legislators' support for opioid use disorder parity laws.

BACKGROUND: In the United States, state behavioral health parity laws play a crucial role in ensuring equitable insurance coverage and access to substance use disorder treatment and services for people that need them. State legislators have the exclusive authority to adopt these laws. The purpose of this study was to identify legislator beliefs independently associated with "strong support" for opioid use disorder (OUD) parity. METHODS: Data were from a 2017 cross-sectional, state-stratified, multi-modal survey of state legislators (N = 475). The dependent variable was "strong support" for OUD parity. Primary independent variables were beliefs about state parity laws. Bivariate analyses and mixed effects logistic regression were conducted. RESULTS: Legislators who "strongly supported" OUD parity were significantly more likely than legislators who did not "strongly support" OUD parity to be female (64.1% vs. 46.5%, p<.001) , Democrat (76.2% vs. 29.3%, p<.001), and have liberal, compared to conservative, ideology (85.6% vs. 27.1%, p<.001). After adjusting for legislator demographics and state-level covariates, beliefs such as agreeing that state parity laws do not increase health insurance premium costs (aOR=6.77, p<.01) and that substance use disorder treatments can be effective (aOR=5.00, p<.001) remained associated with "strong support" for OUD parity. These state legislators' beliefs were more strongly associated with "strong support" for OUD parity than political party, ideology, and other demographic and state-level characteristics. CONCLUSIONS: Dissemination materials and communication strategies to cultivate support for OUD parity laws among state legislators should focus on the fiscal impacts of parity laws and the effectiveness of substance use disorder treatments.

Public transit and depression among older adults: using agent-based models to examine plausible impacts of a free bus policy.

BACKGROUND: Daily transport is associated with mental health. A free bus policy (FBP) may be effective in promoting the use of public transit in older adults and be associated with reductions in depressive symptoms. METHODS: We developed an agent-based model and grounded it using empirical data from England to examine the impact of an FBP on public transit use and depression among older adults. We also used the model to explore whether the impact of the FBP bus use and depression is modified by the type of income segregation or by simultaneous efforts to improve attitudes towards the bus, to reduce waiting times or to increase the cost of driving via parking fees or fuel price. RESULTS: Our model suggests that improving attitudes towards the bus (eg, campaigns that promote bus use) could enhance the effect of the FBP, especially for those in proximity to public transit. Reducing wait times could also significantly magnify FPB impacts, especially in those who live in proximity to public transit. Contrary to expectation, neither fuel costs nor parking fees significantly enhanced the impact of the FBP. The impact of improving attitudes towards the bus and increasing bus frequency was more pronounced in the lower-income groups in an income segregation scenario in which destination and public transit are denser in the city centre. CONCLUSION: Our results suggest that the beneficial mental health effects of an FBP for older adults can be magnified when combined with initiatives that reduce bus waiting times and increased spatial access to transit.
