State-Level Income Inequality as a Determinant of Suicide Mortality in the United States.

Income inequality has been increasing for decades and is now known to be related to many downstream health outcomes, where greater inequality is a predictor of poorer health. Results of investigations into the relationship between income inequality and suicidality have been mixed. This study leverages the most recent data available from the National Longitudinal Mortality Study to investigate the relationship between state-level income inequality and suicide mortality. A series of rigorously controlled logistic regression models, employing multiple measures of inequality, and various suicide mortality case-control specifications are used to investigate the phenomenon. Results indicate that the odds of suicide mortality increase with inequality, and this result is invariant across all models. A reduction in the Gini coefficient from the highest to lowest values of income inequality observed in U.S. states may reduce the odds of suicide mortality by 20 percent to 55 percent or more. Findings have application for social workers and other mental health professionals with respect to clinical assessment and treatment. Likewise, community organizers, policy advocates, and legislators should be aware that policy solutions reducing income inequality in the United States are a mechanism for alleviating the suicide mortality burden.

Development and psychometric properties of the Multidimensional Inventory of Recovery Capital (MIRC).

BACKGROUND: Researchers have developed several instruments to measure recovery capital-the social, physical, human, and cultural resources that help people resolve alcohol and other drug problems. However, existing measures are hampered by theoretical and psychometric weaknesses. The current study reports on process and psychometric outcomes for the Multidimensional Inventory of Recovery Capital (MIRC), a novel measure of recovery capital. METHODS: We used a three-phase, mixed methods approach to develop the MIRC. Individuals who identified as having resolved alcohol problems were recruited in each phase. Phase one focused on item development, with participants providing qualitative feedback on potential items. In phase two (pilot testing) and phase three (final psychometric evaluation), participants completed revised versions of the MIRC to assess its psychometric strength and item performance. RESULTS: Phase one (n=44) resulted in significant item alteration, culminating in a 48-item pilot measure. Pilot testing analyses (n=497) resulted in the deletion or replacement of 17 items. In the final psychometric evaluation (n=482), four additional items were deleted, resulting in a 28-item MIRC comprising four subscales measuring social, physical, human, and cultural capital. The psychometric properties of the final MIRC and its subscales ranged from sound to strong, with high response variability suggesting appropriate item discrimination. CONCLUSION: Results confirm the psychometric strength of the MIRC and underscore the importance of incorporating the insights of diverse samples of people in recovery. The MIRC holds promise as an assessment tool in future research and is available for use at no cost in treatment and community-based settings.

Trauma and principles of trauma-informed care in the U.S. federal legislative response to the opioid epidemic: A policy mapping analysis.

OBJECTIVE: The U.S. declared the opioid epidemic as a national public health emergency in 2017. Given the strong and bidirectional relationship between trauma and substance misuse, policy responses to this crisis that reflect principles of trauma-informed care are especially salient. This study is the first to use trauma-informed policy analysis to systematically assess the U.S. Congressional response to the opioid epidemic. METHOD: We used policy mapping methods to build and analyze a dataset of all opioid-related bills and resolutions proposed in Congress between 2009 and 2017 (N = 188). Following an established trauma-informed policy analysis framework, 2 researchers reviewed these policies and coded their incorporation of trauma-specific language and the principles of safety; choice; trust and transparency; collaboration and peer support; empowerment; and intersectionality. We calculated coding frequencies in these categories and rates of intercoder agreement. RESULTS: A minority of policies (10.6%) directly mentioned trauma and 55% of policies incorporated at least 1 trauma-informed principle. Safety was the most commonly coded principle (38.3%), while intersectionality was the least (6.9%). CONCLUSIONS: Our analysis found limited attention to trauma in opioid-related federal legislation. Based on these findings and following the example of coalitions such as the Campaign for Trauma-Informed Policy and Practice, advocates can mobilize for better inclusion of trauma-informed principles in opioid policy. Further, this study demonstrates the feasibility of applying the trauma-informed policy analysis framework to code Congressional policies using publicly available data, a replicable methodology with potential application at federal and state levels.

Qualitative insights in item development for a comprehensive and inclusive measure of recovery capital.

Background: Item specification is foundational to measurement development but rarely reported in depth. We address this gap by explicating our use of qualitative methods to ground and develop items for a new recovery capital measure, the Multidimensional Inventory of Recovery Capital. Method: We recruited a diverse sample of service providers (n = 9) and people in recovery from alcohol problems (n = 23) to provide feedback on an item pool assessing social, human, physical, community, and cultural capital. Using applied qualitative analysis, we coded findings from interviews and focus groups and made final decisions by consensus regarding item elimination, retention, or revision. This process yielded a 49-item draft measure. Results: Only nine items from an initial 90-item list were retained in their original form. Participant feedback guided item elimination, addition, and revision for linguistic or conceptual clarity. We detected little systematic variation in feedback based on income or race; however, there were stark divergences on particular items based on recovery pathway (i.e. 12-step versus other approaches). Conclusions: The high degree of alteration to the item pool highlights the importance of establishing validity with respondents. Response variation based on recovery pathway suggests the need for broad heterogeneity in respondents. Measures that are sensitive, psychometrically sound, and aligned with theory are critical for advancing research on recovery capital and related disparities for diverse populations.

Psychometric Properties of the Assessment of Recovery Capital (ARC) Instrument in a Diverse Low-Income Sample.

Background: Recovery capital is a theoretical construct elucidating the resources that support recovery from addiction. The 50-item Assessment of Recovery Capital (ARC) instrument and related brief-format versions are the predominant measures of this construct. However, some of the ARC's psychometric properties are not well-established, particularly in racially and economically diverse populations. Objectives: We aimed to determine if the ARC is a valid and reliable measure of recovery capital in a diverse sample. Methods: Paper-and-pencil survey data were collected between March 2017 and May 2018 from a low-income, racially diverse sample of adults in recovery (N = 273). Participants were recruited from nontreatment community settings throughout a mid-sized northeastern U.S. city. They completed the ARC and sociodemographic questions. To determine the ARC's reliability and factor structure, we used item-level analyses and Cronbach's alpha, followed by confirmatory and exploratory factor analyses. Results: Several items performed poorly, having means close to response extremes and problematically small variances. Cronbach's alpha for the full measure was α = .92; however, alphas for the majority of subscales were below .70. The a priori 10-factor model solution failed, preventing interpretation of the confirmatory factor analysis results. Exploratory factor analysis revealed that although the 10-factor model marginally fit the data, items did not load together as proposed. Not once did all five subscale items load highly on the same factor. Conclusions/Importance: The ARC has substantial weaknesses in its theoretical alignment, item performance, and psychometric properties with diverse populations. We recommend the development of a new multidimensional, theory-aligned measure, following a rigorous measurement development protocol.

A policy mapping analysis of goals, target populations, and punitive notions in the U.S. congressional response to the opioid epidemic.

BACKGROUND: The U.S. Congress has proposed numerous bills and resolutions in response to the opioid epidemic unfolding over the past decade. Although this legislative response has been the subject of considerable media attention and commentary, very little research has systematically analyzed congressional opioid-related legislation in terms of primary goals, focal populations, and the extent to which it includes punitive mechanisms. METHODS: To address this gap in research, we conducted a policy mapping content analysis of all opioid-related bills and resolutions (N = 188) proposed in Congress between 2009-2017 (111th - 115th Congresses). Two researchers independently coded basic characteristics (e.g. type, status, sponsorship, funding); goals, using a taxonomy developed by the researchers; focal populations; and punitive intent. Researchers compared codes and addressed discrepancies through consensus. RESULTS: Legislation addressed a wide range of goals, but frequently did not advance beyond the introduction stage (80.3%). Goals most often centered on treatment (43.1% of legislation), research (36.7%), and supply reduction of licit (34.0%) and illicit opioids (21.3%). Relatively little legislation addressed long-term recovery, avenues of safer drug consumption, or stigma reduction. Youth (21.3%) and veterans (17.0%) were the most common population categories toward which legislation was directed. Explicit attention toward racial/ethnic minorities, low-income populations, and sexual minorities was rare to nonexistent. Legislation was largely coded as not directly punitive (91.0%). CONCLUSION: This study represents the first systematic analysis of key features of the U.S. congressional response to the opioid epidemic. Results indicate that the legislative response has largely focused on acute intervention, with limited attention to upstream social determinants and goal areas such as long-term recovery support. While the legislative response is primarily non-punitive, most opioid-specific policy does not explicitly address the intersection of opioid misuse and addiction with salient social factors such as economic disinvestment and social isolation.

'Hello, you're not supposed to be here': homeless emerging adults' experiences negotiating food access.

OBJECTIVE: We aimed to examine the food-seeking experiences of homeless emerging adults (age 18-24 years) in a US urban context. DESIGN: The study used a qualitative descriptive design, combining semi-structured interviews with a standardized quantitative measure of food insecurity. Interview data were coded using constant comparative methods to identify patterns across and within interviews. Emerging themes were confirmed and refined through member checking. SETTING: Buffalo, a mid-sized city in the Northeastern USA. SUBJECTS: A sample of thirty participants was recruited through community-based methods. Eligibility criteria specified that participants were aged 18-24 years and did not have a stable place to live. The sample was demographically diverse and included participants who were couch-surfing, staying on the streets and/or using shelters. RESULTS: Participants' food access strategies varied across their living circumstances. Common strategies included purchasing food with cash or benefits (reported by 77 %), using free meal programmes (70 %) and eating at friends' or relatives' homes (47 %). Although 70 % of participants received Supplemental Nutrition Assistance Program benefits, several reported access barriers, including initial denials of eligibility due to being listed on a parent's application even when the participant no longer resided in the household. Participants described a stigma associated with using food pantries and free meal programmes and expressed preference for less institutionalized programmes such as Food Not Bombs. CONCLUSIONS: Given endemic levels of food insecurity among homeless youth and young adults, policy modifications and service interventions are needed to improve food access for this population.

Sources of variability in platelet accumulation on type 1 fibrillar collagen in microfluidic flow assays.

Microfluidic flow assays (MFA) that measure shear dependent platelet function have potential clinical applications in the diagnosis and treatment of bleeding and thrombotic disorders. As a step towards clinical application, the objective of this study was to measure how phenotypic and genetic factors, as well as experimental conditions, affect the variability of platelet accumulation on type 1 collagen within a MFA. Whole blood was perfused over type 1 fibrillar collagen at wall shear rates of 150, 300, 750 and 1500 s⁻¹ through four independent channels with a height of 50 µm and a width of 500 µm. The accumulation of platelets was characterized by the lag time to 1% platelet surface coverage (Lag(T)), the rate of platelet accumulation (V(PLT)), and platelet surface coverage (SC). A cohort of normal donors was tested and the results were correlated to plasma von Willebrand factor (VWF) levels, platelet count, hematocrit, sex, and collagen receptors genotypes. VWF levels were the strongest determinant of platelet accumulation. VWF levels were positively correlated to V(PLT) and SC at all wall shear rates. A longer Lag(T) for platelet accumulation at arterial shear rates compared to venous shear rates was attributed to the time required for plasma proteins to adsorb to collagen. There was no association between platelet accumulation and hematocrit or platelet count. Individuals with the AG genotype of the GP6 gene had lower platelet accumulation than individuals with the AA genotype at 150 s⁻¹ and 300 s⁻¹. Recalcified blood collected into sodium citrate and corn trypsin inhibitor (CTI) resulted in diminished platelet accumulation compared to CTI alone, suggesting that citrate irreversibly diminishes platelet function. This study the largest association study of MFA in healthy donors (n = 104) and will likely set up the basis for the determination of the normal range of platelet responses in this type of assay.
