Toward Population Health: Using a Learning Behavioral Health System and Measurement-Based Care to Improve Access, Care, Outcomes, and Disparities.

Achieving population behavioral health is urgently needed. The mental health system struggles with enormous challenges of providing access to mental health services, improving quality and equitability of care, and ensuring good health outcomes across subpopulations. Little data exists about increasing access within highly constrained resources, staging/sequencing treatment along care pathways, or personalizing treatments. The conceptual model of the learning healthcare system offers a potential paradigm shift for addressing these challenges. In this article we present an overview of how the three constructs of population health, learning health systems, and measurement-based care are inter-related, and we provide an example of how one academic, community-based, safety net health system is approaching integrating these paradigms into its service delivery system. Implementation outcomes will be described in a subsequent publication. We close by discussing how ultimately, to meaningfully improve population behavioral health, a learning healthcare system could expand into a learning health community in order to target critical points of prevention and intervention.

An exploratory study of Mindfulness Based Stress Reduction for emotional eating.

Emotional eating is an important predictor of weight loss and weight regain after weight loss. This two part study's primary aim was to explore changes in emotional eating in a general population of individuals taking the Mindfulness Based Stress Reduction (MBSR) program, with a secondary aim to explore whether changes in mindfulness predicted changes in emotional eating. Self-reported survey data exploring these questions were collected before and after the intervention for two sequential studies (Study 1 and Study 2). While there were no control groups for either study, in both studies emotional eating scores following the MBSR were significantly lower than scores prior to taking the MBSR (p < 0.001; p < 0.001) In Study 2, changes in mindfulness were correlated with changes in emotional eating (r = 0.317, p = 0.004). These results suggest that MBSR may be an effective intervention for emotional eating, and that further research is warranted to examine effects on weight loss and maintenance.

Mindfulness and Cardiovascular Disease Risk: State of the Evidence, Plausible Mechanisms, and Theoretical Framework.

The purpose of this review is to provide (1) a synopsis on relations of mindfulness with cardiovascular disease (CVD) and major CVD risk factors, and (2) an initial consensus-based overview of mechanisms and theoretical framework by which mindfulness might influence CVD. Initial evidence, often of limited methodological quality, suggests possible impacts of mindfulness on CVD risk factors including physical activity, smoking, diet, obesity, blood pressure, and diabetes regulation. Plausible mechanisms include (1) improved attention control (e.g., ability to hold attention on experiences related to CVD risk, such as smoking, diet, physical activity, and medication adherence), (2) emotion regulation (e.g., improved stress response, self-efficacy, and skills to manage craving for cigarettes, palatable foods, and sedentary activities), and (3) self-awareness (e.g., self-referential processing and awareness of physical sensations due to CVD risk factors). Understanding mechanisms and theoretical framework should improve etiologic knowledge, providing customized mindfulness intervention targets that could enable greater mindfulness intervention efficacy.

Determinants of remote measurement-based care uptake in a safety net outpatient psychiatry department as part of learning health system transition.

Introduction: Behavioral measurement-based care (MBC) can improve patient outcomes and has also been advanced as a critical learning health system (LHS) tool for identifying and mitigating potential disparities in mental health treatment. However, little is known about the uptake of remote behavioral MBC in safety net settings, or possible disparities occurring in remote MBC implementation. Methods: This study uses electronic health record data to study variation in completion rates at the clinic and patient level of a remote MBC symptom measure tool during the first 6 months of implementation at three adult outpatient psychiatry clinics in a safety net health system. Provider-reported barriers to MBC adoption were also measured using repeated surveys at one of the three sites. Results: Out of 1219 patients who were sent an MBC measure request, uptake of completing at least one measure varied by clinic: General Adult Clinic, 38% (n = 262 of 696); Substance Use Clinic, 28% (n = 73 of 265); and Transitions Clinic, 17% (n = 44 of 258). Compared with White patients, Black and Portuguese or Brazilian patients had lower uptake. Older patients also had lower uptake. Spanish language of care was associated with much lower uptake at the patient level. Significant patient-level disparities in uptake persisted after adjusting for the clinic, mental health diagnoses, and number of measure requests sent. Providers cited time within visits and bandwidth in their workflow as the greatest consistent barriers to discussing MBC results with patients. Conclusions: There are significant disparities in MBC uptake at the patient and clinic level. From an LHS data infrastructure perspective, safety net health systems may need to address the need for possible ways to adapt MBC to better fit their populations and clinical needs, or identify targeted implementation strategies to close data gaps for the identified disparity populations.

Predictors of Accessing Substance Abuse Services Among Individuals With Mental Disorders Released From Correctional Custody.

OBJECTIVE: In the context of an increasing correctional population and corresponding rates of mental illness and substance abuse among this population, this study focuses on describing the predictors of substance abuse service utilization for ex-inmates with dual disorders. Our aim is to assess the likelihood and characteristics of ex-inmates with mental disorders who access substance abuse treatment services within two years of correctional release. METHODS: Using merged administrative data on all ex-inmates with open mental health cases released from Massachusetts Department of Corrections and two County Houses of Corrections from 2007 to 2009 (N=2,280) and substance abuse treatment outcome data through 2011, we analyze the influence of demographics, behavioral and mental disorders, and criminal justice variables on entry into substance abuse treatment within 24 months post release. We also describe primary drug use and services utilized for all the ex-inmates who accessed substance abuse services (N=1,383). Regression techniques were used to analyze the probability of utilizing substance abuse treatment services by various demographic, behavioral, and criminal involvement characteristics. RESULTS: The prevalence of a history of substance use disorders is high in this population (69%; n = 1,285). Subsequently, at 24 months post release 61% (n = 1,383) of ex-inmates with open mental health cases utilized substance abuse treatment services. This group was disproportionately female, with a preincarceration history of substance abuse, an increased number of previous incarcerations, and more likely released under correctional supervision. CONCLUSIONS: Substance abuse is a chronic relapsing disorder and dual diagnosis is common among individuals with mental disorders involved with the criminal justice system. Their service needs and contacts across substance abuse, mental health, and criminal justice systems highlight individuals caught up in the institutional circuit. Study results point to the need for expanded and targeted dual diagnosis treatment approaches and relapse prevention for ex-inmates with mental disorders post correctional release.

Participants' Engagement With and Results From a Web-Based Integrative Population Mental Wellness Program (CHAMindWell) During the COVID-19 Pandemic: Program Evaluation Study.

BACKGROUND: The COVID-19 pandemic involved a prolonged period of collective trauma and stress during which substantial increases in mental health concerns, like depression and anxiety, were observed across the population. In this context, CHAMindWell was developed as a web-based intervention to improve resilience and reduce symptom severity among a public health care system's patient population. OBJECTIVE: This program evaluation was conducted to explore participants' engagement with and outcomes from CHAMindWell by retrospectively examining demographic information and mental health symptom severity scores throughout program participation. METHODS: We examined participants' symptom severity scores from repeated, web-based symptom screenings through Computerized Adaptive Testing for Mental Health (CAT-MH) surveys, and categorized participants into symptom severity-based tiers (tier 1=asymptomatic to mild; tier 2=moderate; and tier 3=severe). Participants were provided tier-based mindfulness resources, treatment recommendations, and referrals. Logistic regressions were conducted to evaluate associations between demographic variables and survey completion. The McNemar exact test and paired sample t tests were performed to evaluate changes in the numbers of participants in tier 1 versus tier 2 or 3 and changes in depression, anxiety, and posttraumatic stress disorder severity scores between baseline and follow-up. RESULTS: The program enrolled 903 participants (664/903, 73.5% female; 556/903, 61.6% White; 113/903, 12.5% Black; 84/903, 9.3% Asian; 7/903, 0.8% Native; 36/903, 4% other; and 227/903, 25.1% Hispanic) between December 16, 2020, and March 17, 2022. Of those, 623 (69%) completed a baseline CAT-MH survey, and 196 completed at least one follow-up survey 3 to 6 months after baseline. White racial identity was associated with completing baseline CAT-MH (odds ratio [OR] 1.80, 95% CI 1.14-2.84; P=.01). Participants' odds of having symptom severity below the clinical threshold (ie, tier 1) were significantly greater at follow-up (OR 2.60, 95% CI 1.40-5.08; P=.001), and significant reductions were observed across symptom domains over time. CONCLUSIONS: CHAMindWell is associated with reduced severity of mental health symptoms. Future work should aim to address program engagement inequities and attrition and compare the impacts of CHAMindWell to a control condition to better characterize its effects.

Prefrontal regional correlates of self-control in male psychiatric patients: Impulsivity facets and aggression.

Investigating the organization of trait aggression and impulsivity in the prefrontal cortex (PFC) advances our understanding of the neuropsychobiology of self-control. While the orbital aspect of the PFC (OFC) has received attention, there is reason to believe the lateral aspect is also relevant. In the current study using magnetic resonance imaging, gray matter volumes in lateral PFC (LPFC) were derived in a heterogeneous male psychiatric sample (N=36) in which OFC volumes had previously been reported. In an analysis using self-report measures of trait impulsivity and aggression, the left LPFC accounted for significant variance in attentional aspects of impulsivity (13%) and aggression (10%) but not motor aspects of impulsivity, as hypothesized. The OFC was associated with motor impulsivity (left-20%; right-14%) and was also more robustly associated with aggression (left-36%; right-16%). A social/emotional information processing model was explored, based upon whether the LPFC or the OFC depended upon one another for their association to trait aggression and impulsivity. It was demonstrated that association of the LPFC to both aggression and attentional impulsivity depended upon the OFC, while the converse was not supported. The LPFC appears relevant to the higher-order aspects of a cortical self-control network, and that relevance is dependent upon the robust contribution of the OFC.

Promoting Population Behavioral Health in a Safety-Net Health System During the COVID-19 Pandemic.

The COVID-19 pandemic has been expected to lead to substantial increases in need for behavioral health care. A population health framework can facilitate the development of interventions and policies to promote the equitable distribution of care across the population. This column describes the application of population behavioral health principles in a safety-net health system during the pandemic. The approach includes stepped models of care, interventions to target individuals at high behavioral health risk, and measurement-based care. Early data suggest that these strategies have resulted in expanded behavioral health care capacity.

Keeping weight off: Mindfulness-Based Stress Reduction alters amygdala functional connectivity during weight loss maintenance in a randomized control trial.

Obesity is associated with significant comorbidities and financial costs. While behavioral interventions produce clinically meaningful weight loss, weight loss maintenance is challenging. The objective was to improve understanding of the neural and psychological mechanisms modified by mindfulness that may predict clinical outcomes. Individuals who intentionally recently lost weight were randomized to Mindfulness-Based Stress Reduction (MBSR) or a control healthy living course. Anthropometric and psychological factors were measured at baseline, 8 weeks and 6 months. Functional connectivity (FC) analysis was performed at baseline and 8 weeks to examine FC changes between regions of interest selected a priori, and independent components identified by independent component analysis. The association of pre-post FC changes with 6-month weight and psychometric outcomes was then analyzed. Significant group x time interaction was found for FC between the amygdala and ventromedial prefrontal cortex, such that FC increased in the MBSR group and decreased in controls. Non-significant changes in weight were observed at 6 months, where the mindfulness group maintained their weight while the controls showed a weight increase of 3.4% in BMI. Change in FC at 8-weeks between ventromedial prefrontal cortex and several ROIs was associated with change in depression symptoms but not weight at 6 months. This pilot study provides preliminary evidence of neural mechanisms that may be involved in MBSR's impact on weight loss maintenance that may be useful for designing future clinical trials and mechanistic studies.

Emotion-related constructs engaged by mindfulness-based interventions: A systematic review and meta-analysis.

OBJECTIVES: Mindfulness-based interventions (MBIs) have been widely implemented to improve self-regulation behaviors, often by targeting emotion-related constructs to facilitate change. Yet the degree to which MBIs engage specific measures of emotion-related constructs has not been systematically examined. METHODS: Using advanced meta-analytic techniques, this review examines construct and measurement engagement in trials of adults that used standardized applications of the two most established MBIs: Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Cognitive Therapy (MBCT), or modified variations of these interventions that met defined criteria. RESULTS: Seventy-two studies (N=7,378) were included (MBSR k=47, MBCT k = 21, Modified k=4). MBIs led to significant improvement in emotion-related processing overall, compared to inactive controls (d=0.58; k =36), and in all constructs assessed: depression (d=0.66; k=26), anxiety (d =0.63; k=19), combined mental health (d =0.75; k=7 ) and stress (d =0.44; k=11). Reactions to pain, mood states, emotion regulation, and biological measures lacked sufficient data for analysis. MBIs did not outperform active controls in any analyses. Measurement tool and population-type did not moderate results, but MBI-type did, in that MBCT showed stronger effects than MBSR, although these effects were driven by a small number of studies. CONCLUSIONS: This review is the first to examine the full scope of emotion-related measures relevant to self-regulation, to determine which measures are most influenced by MBCT/MBSR. Compared to extant reviews, which typically focused on MBI outcomes, this work examined mechanistic processes based on measurement domains and tools. While effect sizes were similar among measurement tools, this review also includes a descriptive evaluation of measures and points of caution, providing guidance to MBI researchers and clinicians for selection of emotion-related measurement tools.

Mindfulness and Behavior Change.

Initiating and maintaining behavior change is key to the prevention and treatment of most preventable chronic medical and psychiatric illnesses. The cultivation of mindfulness, involving acceptance and nonjudgment of present-moment experience, often results in transformative health behavior change. Neural systems involved in motivation and learning have an important role to play. A theoretical model of mindfulness that integrates these mechanisms with the cognitive, emotional, and self-related processes commonly described, while applying an integrated model to health behavior change, is needed. This integrative review (1) defines mindfulness and describes the mindfulness-based intervention movement, (2) synthesizes the neuroscience of mindfulness and integrates motivation and learning mechanisms within a mindful self-regulation model for understanding the complex effects of mindfulness on behavior change, and (3) synthesizes current clinical research evaluating the effects of mindfulness-based interventions targeting health behaviors relevant to psychiatric care. The review provides insight into the limitations of current research and proposes potential mechanisms to be tested in future research and targeted in clinical practice to enhance the impact of mindfulness on behavior change.

Hemispheric connectivity and the visual-spatial divergent-thinking component of creativity.

BACKGROUND/HYPOTHESIS: Divergent thinking is an important measurable component of creativity. This study tested the postulate that divergent thinking depends on large distributed inter- and intra-hemispheric networks. Although preliminary evidence supports increased brain connectivity during divergent thinking, the neural correlates of this characteristic have not been entirely specified. It was predicted that visuospatial divergent thinking would correlate with right hemisphere white matter volume (WMV) and with the size of the corpus callosum (CC). METHODS: Volumetric magnetic resonance imaging (MRI) analyses and the Torrance Tests of Creative Thinking (TTCT) were completed among 21 normal right-handed adult males. RESULTS: TTCT scores correlated negatively with the size of the CC and were not correlated with right or, incidentally, left WMV. CONCLUSIONS: Although these results were not predicted, perhaps, as suggested by Bogen and Bogen (1988), decreased callosal connectivity enhances hemispheric specialization, which benefits the incubation of ideas that are critical for the divergent-thinking component of creativity, and it is the momentary inhibition of this hemispheric independence that accounts for the illumination that is part of the innovative stage of creativity. Alternatively, decreased CC size may reflect more selective developmental pruning, thereby facilitating efficient functional connectivity.

A multivariate approach to aggression and the orbital frontal cortex in psychiatric patients.

The association between orbital frontal cortex (OFC) volume and aggression was investigated in an at-risk psychiatric population. Forty-one psychiatric patients were referred for magnetic resonance imaging and a standardized psychometric assessment of aggression (Lifetime History of Aggression-Revised). Nineteen matched controls had lower levels of aggression and greater OFC volume, establishing the appropriateness of the psychiatric group for studying aggression pathophysiology. Consistent with study hypotheses, left OFC gray matter volume predicted 34% of the variance in self-reported aggression ratings. When impulsivity was not controlled for, left OFC gray matter only accounted for 26% of aggression variance, suggesting a complex relationship between impulsivity and OFC-aggression pathophysiology. Contrary to study hypotheses, right OFC gray matter volume did not predict degree of aggressive behavior. Current models do not account for lateralization, yet this may be quite important. Greater consideration should be given to laterality in OFC regulation of social/emotional behavior. Regulatory focus theory, positing two motivational systems, promotion and prevention, lateralized to the left and right hemispheres, respectively, may provide an explanatory framework for these results. Dysregulation of the left hemisphere 'promotion' motivational system may help to explain the aggressive behavior present in psychiatric populations.

Considerations for mood and emotion measures in mindfulness-based intervention research.

A large and growing body of work has examined the effects of Mindfulness-Based Interventions (MBI's), such as Mindfulness-Based Stress Reduction and Mindfulness-Based Cognitive Therapy, on emotion-related outcomes, both in mental health settings and general populations. These studies vary widely in the approach to measurement of emotion-related measurements after MBI's. A systematic review of randomized clinical trials of MBIs was conducted with a focus on identifying what emotion-related assays were able to detect changes with MBI's, including scales and instruments (both self-report and clinician-rated) on constructs such as depression, anxiety, emotion regulation, and other mood states. In this paper, we reflect on these findings and discuss considerations of outcome measures in MBI research. There are previously established practices for clinical trials research on emotion-related outcomes which may provide some useful methodological standards and study design options for use by the MBI research field.

Feasibility and Acceptability of Mindfulness for Survivors of Homicide and Their Providers.

PURPOSE: This study uses participatory research methods with survivors of homicide and their service providers to explore the feasibility and acceptability of a culturally adapted mindfulness intervention for stress reduction and resilience in homicide survivors. PROCEDURES: Our mixed methods approach included: (a) previewing a Mindfulness-Based Stress Reduction program with providers and survivors; (b) using their iterative feedback during focus groups to revise the curriculum; and (c) studying the acceptability of the adapted curriculum for survivors through focus group and standardized data collection. FINDINGS: We learned that providers use mindfulness for self-care and both providers and survivors view the approach for survivors as promising. Based on attendance, participation, and focus group data, the adapted curriculum was both feasible and acceptable. Survivors' reports suggested most experienced improved emotion regulation, feelings of empowerment, and better coping. CONCLUSIONS: Culturally adapted mindfulness programs may support healing for homicide survivors and possibly other low-income people of color with significant trauma backgrounds. Further investigation is needed to rigorously assess outcomes and specific effects, both positive and negative, of mindfulness in this and other more diversified populations.

Relationship of mindful awareness to neural processing of angry faces and impact of mindfulness training: A pilot investigation.

Mindfulness is paying attention, non-judgmentally, to experience in the moment. Mindfulness training reduces depression and anxiety and influences neural processes in midline self-referential and lateralized somatosensory and executive networks. Although mindfulness benefits emotion regulation, less is known about its relationship to anger and the corresponding neural correlates. This study examined the relationship of mindful awareness and brain hemodynamics of angry face processing, and the impact of mindfulness training. Eighteen healthy volunteers completed an angry face processing fMRI paradigm and measurement of mindfulness and anger traits. Ten of these participants were recruited from a Mindfulness-Based Stress Reduction (MBSR) class and also completed imaging and other assessments post-training. Self-reported mindful awareness increased after MBSR, but trait anger did not change. Baseline mindful awareness was negatively related to left inferior parietal lobule activation to angry faces; trait anger was positively related to right middle frontal gyrus and bilateral angular gyrus. No significant pre-post changes in angry face processing were found, but changes in trait mindful awareness and anger were associated with sub-threshold differences in paralimbic activation. These preliminary and hypothesis-generating findings, suggest the analysis of possible impact of mindfulness training on anger may begin with individual differences in angry face processing.

Orbitofrontal correlates of aggression and impulsivity in psychiatric patients.

The association between orbital frontal cortex (OFC) volume and aggression and impulsivity was investigated among a heterogeneous group of non-psychotic psychiatric clients. Fifteen non-psychotic subjects from two different psychiatric clinics (New England Medical Center and Lemuel Shattuck Hospital) with a variety of diagnoses were sequentially referred for magnetic resonance imaging (MRI) for clinical purposes. This convenience sample, clinically stable at the time of evaluation, received a standardized psychiatric diagnostic interview, aggression and impulsivity psychometrics (Barratt Impulsivity, Lifetime History of Aggression, and Buss-Perry Aggression scales), and an MRI protocol with image analysis. OFC gray matter volume, total as well as left and right, was significantly and positively associated with motor impulsivity. OFC asymmetry was associated with aggression, though total, left, and right OFC volume measurements were not. For subjects without affective disorder, there was a strong and positive association of the OFC to motor and no-planning subscales of the Barratt Impulsivity Scale. For subjects with affective disorder, there was a strong association of OFC asymmetry to both of the aggression psychometrics. Consistent with expectation, results are suggestive of OFC involvement in the neural circuitry of impulsivity and aggression. The findings suggest a dissociation of the role of the OFC in relation to aggression and impulsivity, such that the OFC may play a part in the regulation of aggressive behavior and a generative role in impulsive behavior.

Keeping Weight Off: study protocol of an RCT to investigate brain changes associated with mindfulness-based stress reduction.

INTRODUCTION: Obesity is a growing epidemic fuelled by unhealthy behaviours and associated with significant comorbidities and financial costs. While behavioural interventions produce clinically meaningful weight loss, weight loss maintenance is challenging. This may partially be due to failure to target stress and emotional reactivity. Mindfulness-based stress reduction (MBSR) reduces stress and emotional reactivity and may be a useful tool for behaviour change maintenance. This study seeks to provide a mechanistic understanding for clinical trials of the benefits of MBSR for weight loss maintenance by examining changes in functional connectivity (FC) and the association of these changes with clinical outcomes. METHODS AND ANALYSIS: Community-dwelling individuals (n=80) who intentionally lost ≥5% of their body weight in the past year will be recruited and randomised to an MBSR programme or educational control. FC using resting-state functional MRI will be measured at baseline and 8 weeks. Psychological factors, health behaviours, body mass index and waist circumference will be measured at baseline, 8 weeks and 6 months post intervention. A 12-month telephone follow-up will assess self-reported weight. Analyses will characterise FC changes in response to MBSR in comparison with a control condition, assess the relationship between baseline FC status and pre-post MBSR changes in FC and investigate the association of FC change with changes in psychological factors and weight loss maintenance. ETHICS AND DISSEMINATION: The University of Massachusetts Medical School Institutional Review Board has approved this study, Declaration of Helsinki protocols are being followed, and patients will give written informed consent. The Independent Monitoring Committee will monitor protocol adherence. Results from the study will be disseminated to the medical community at conferences and submitted for publication in peer-reviewed journals when the last patient included has been followed up for 12 months. TRIAL REGISTRATION NUMBER: NCT02189187.

Impulsive-aggressive traits, serotonin function, and alcohol-enhanced aggression.

Although alcohol consumption is involved in most acts of violence, most people do not become violent when they drink. Individuals also respond differently to alcohol on laboratory measures of aggression. The objective of this study was to determine whether individual differences in the effects of alcohol on a laboratory measure of aggression are related to specific personality traits and/or serotonin function, as measured by prolactin response to pharmacochallenge. Psychometric scales for impulsiveness, aggression, and anger, as well as a probe for suspiciousness, were administered to 10 healthy male social drinkers. Trait serotonin function was determined by citalopram challenge. The effect of alcohol on the Point Subtraction Aggression Paradigm was determined by comparing aggression scores with and without 1 g/kg alcohol. Impulsivity scores were significantly correlated with the change in aggressive responding after alcohol. Aggression, anger, and suspiciousness scores were not. Prolactin response did not predict the effect of alcohol on aggressive responding. The results suggest that trait impulsiveness may mediate the effects of alcohol on aggression in normal males.

Mindfulness-Based Interventions for Weight Loss and CVD Risk Management.

Obesity affects more than one-third of U.S. adults and is a major cause of preventable morbidity and mortality, primarily from cardiovascular disease. Traditional behavioral interventions for weight loss typically focus on diet and exercise habits and often give little attention to the role of stress and emotions in the initiation and maintenance of unhealthy behaviors, which may account for their modest results and considerable variability in outcomes. Stress eating and emotional eating are increasingly recognized as important targets of weight loss interventions. Mindfulness-based interventions were specifically developed to promote greater self-efficacy in coping with stress and negative emotions, and appear to be effective for a variety of conditions. In recent years researchers have begun to study mindfulness interventions for weight loss and CVD risk management. This review describes the rationale for the use of mindfulness in interventions for weight loss and CVD risk management, summarizes the research to date, and suggests priorities for future research.
