Quanto à frequência de transtornos psiquiátricos identificados, 49,6% (n=226) dos participantes apresentaram sintomas depressivos, 29,8% (n=136) exibiram ideação suicida, 55,7% (n=254) informaram uso de álcool semanalmente, 34,2% (n=156) informaram usar drogas ilícitas semanalmente e 62,3% (n=284) tinham problemas com sono. Conclusões: A prevalência de condições que afetam a saúde mental entre os participantes é alta. Estes resultados poderão auxiliar profissionais de saúde na elaboração de estratégias de prevenção e tratamento nessa população, pouco estudada.

Introduction: The present study aims to describe the most prevalent mental health conditions in the homeless population in a large Brazilian urban center. Objective: To describe the most prevalent mental health conditions in the population of homeless people in a large Brazilian urban center. Methods: This is a cross-sectional study carried out in the central and periphery regions of São Paulo, state of São Paulo, Brazil. For the description of psychiatric disorders, the following instruments were used: Patient Health Questionnaire-9 (PHQ-9) for depressive symptoms, item 9 of the Beck Depression Inventory for suicidal ideation, the self-reported question for the use of alcohol and illicit drugs, and item 3 of the PHQ-9 for sleep quality. Results: The mean age of participants was 44.54 (Standard Deviation=12.63) years, and most were men (n=342; 75%). Regarding the frequency of the identified psychiatric disorders, 49.6% (n=226) of the participants had depressive symptoms, 29.8% (n=136) had suicidal ideation, 55.7% (n=254) reported weekly alcohol use, 34.2% (n=156) reported using illicit drugs weekly, and 62.3% (n=284) had sleep problems. Conclusions: The prevalence of conditions that affect mental health among participants is high. These results may help health professionals to develop prevention and treatment strategies for this understudied population.

Preferences Regarding Information Strategies for Digital Mental Health Interventions Among Medical Students: Discrete Choice Experiment.

BACKGROUND: Digital mental health interventions (DMHIs) are capable of closing gaps in the prevention and therapy of common mental disorders. Despite their proven effectiveness and approval for prescription, use rates remain low. The reasons include a lack of familiarity and knowledge as well as lasting concerns. Medical students were shown to have a comparatively higher risk for common mental disorders and are thus an important target group for raising awareness about DMHIs. At best, knowledge is already imparted during medical school using context-sensitive information strategies. Yet, little is known about medical students' information preferences regarding DMHIs. OBJECTIVE: This study aims to explore information preferences for DMHIs for personal use among medical students in Germany. METHODS: A discrete choice experiment was conducted, which was developed using an exploratory sequential mixed methods research approach. In total, 5 attributes (ie, source, delivery mode, timing, recommendation, and quality criteria), each with 3 to 4 levels, were identified using formative research. Data were analyzed using logistic regression models to estimate preference weights and the relative importance of attributes. To identify subgroups of students varying in information preferences, we additionally performed a latent class analysis. RESULTS: Of 309 participants, 231 (74.8%) with reliable data were included in the main analysis (women: 217/309, 70.2%; age: mean 24.1, SD 4.0 y). Overall, the conditional logit model revealed that medical students preferred to receive information about DMHIs from the student council and favored being informed via social media early (ie, during their preclinic phase or their freshman week). Recommendations from other students or health professionals were preferred over recommendations from other users or no recommendations at all. Information about the scientific evidence base was the preferred quality criterion. Overall, the timing of information was the most relevant attribute (32.6%). Latent class analysis revealed 2 distinct subgroups. Class 1 preferred to receive extensive information about DMHIs in a seminar, while class 2 wanted to be informed digitally (via email or social media) and as early as possible in their studies. CONCLUSIONS: Medical students reported specific needs and preferences regarding DMHI information provided in medical school. Overall, the timing of information (early in medical education) was considered more important than the information source or delivery mode, which should be prioritized by decision makers (eg, members of faculties of medicine, universities, and ministries of education). Study findings suggest general and subgroup-specific information strategies, which could be implemented in a stepped approach. Easily accessible digital information may promote students' interest in DMHIs in the first step that might lead to further information-seeking behavior and the attendance of seminars about DMHIs in the second step.

Design of a multicenter randomized controlled trial of a post-discharge suicide prevention intervention for high-risk psychiatric inpatients: The Veterans Coordinated Community Care Study.

BACKGROUND: The period after psychiatric hospital discharge is one of elevated risk for suicide-related behaviors (SRBs). Post-discharge clinical outreach, although potentially effective in preventing SRBs, would be more cost-effective if targeted at high-risk patients. To this end, a machine learning model was developed to predict post-discharge suicides among Veterans Health Administration (VHA) psychiatric inpatients and target a high-risk preventive intervention. METHODS: The Veterans Coordinated Community Care (3C) Study is a multicenter randomized controlled trial using this model to identify high-risk VHA psychiatric inpatients (n = 850) randomized with equal allocation to either the Coping Long Term with Active Suicide Program (CLASP) post-discharge clinical outreach intervention or treatment-as-usual (TAU). The primary outcome is SRBs over a 6-month follow-up. We will estimate average treatment effects adjusted for loss to follow-up and investigate the possibility of heterogeneity of treatment effects. RESULTS: Recruitment is underway and will end September 2024. Six-month follow-up will end and analysis will begin in Summer 2025. CONCLUSION: Results will provide information about the effectiveness of CLASP versus TAU in reducing post-discharge SRBs and provide guidance to VHA clinicians and policymakers about the implications of targeted use of CLASP among high-risk psychiatric inpatients in the months after hospital discharge.

Performance replication of the Hospital Mental Health Risk Screen in ethnoracially diverse U.S. patients admitted through emergency care.

BACKGROUND: Patients admitted to hospitals after emergency care for injury or acute illness are at risk for later mental health problems. The American College of Surgeons Committee on Trauma Standards for care of injured patients call for mental health risk screening, and the Hospital Mental Health Risk Screen (HMHRS) accurately identified at-risk patients in a developmental study that included patients from five ethnoracial groups. Replication of these findings is essential, because initial positive results for predictive screens can fail to replicate if the items were strongly related to outcomes in the development sample but not in a new sample from the population the screen was intended for. STUDY DESIGN: Replication of the predictive performance of the 10-item HMHRS was studied prospectively in ethnoracially diverse patients admitted after emergency care for acute illness or injury in three hospitals across the U.S. RESULTS: Risk screen scores and follow-up mental health outcomes were obtained for 452 of 631 patients enrolled (72%). A cut score of 10 on the HMHRS correctly identified 79% of the patients who reported elevated levels of depression, anxiety, and PTSD symptoms two months post-admission (sensitivity) and 72% of the patients whose symptoms were not elevated (specificity). HMHRS scores also predicted well for patients with acute illness, for patients with injuries, and for patients who reported an Asian American/Pacific Islander, Black, Latinx, Multirace, or White identity. CONCLUSIONS: Predictive performance of the HMHRS was strong overall and within all five ethnoracial subgroups. Routine screening could reduce suffering and health care costs, increase health and mental health equity, and foster preventive care research and implementation. The performance of the HMHRS should be studied in other countries and in other populations of recent trauma survivors, such as survivors of disaster or mass violence.

Mobile Delivery Program to Prevent Relapse and Improve Functioning in Patients With Psychiatric Diseases.

The term "revolving door patients" refers to those who are frequently rehospitalized for relapse. This phenomenon can be explained by a multitude of factors, including a lack of medical and/or social support. On the basis of a review of various modalities of psychiatric treatment, such as long-acting injectables, assisted outpatient treatment, and telehealth, it is clear that a major underlying issue among people with psychiatric diseases who lack insight into their mental and physical health is medication nonadherence. Therefore, we propose a mobile delivery program (MDP) in which health care professionals deliver medications and care to psychiatric patients in their own homes. The target patient population for MDP is patients with medication nonadherence, frequent emergency department visits, and missed appointments. Patients with mental illnesses, especially schizophrenia, are disproportionately represented among the homeless and incarcerated populations. By implementing MDP, we can help break the cycle of incarceration for patients with mental illnesses and homelessness. In addition, the cost of transportation and salaries for the mobile delivery team would be considerably lower than the billions of dollars spent each year due to relapses, emergency department visits, inpatient admissions, and crime leading to long-term stays in correctional facilities. This model has the potential to reduce relapse, improve functioning, and reduce excess morbidity and mortality. Substantial cost savings for health services can, in turn, be expected.

Factors Influencing Primary Care Access for Common Mental Health Conditions Among Adults in West Africa: Protocol for a Scoping Review.

BACKGROUND: Mental health conditions are expressed in various ways in different people, and access to health care for these conditions is affected by individual factors, health care provider factors, and contextual factors. These factors may be enablers or barriers to accessing primary care for mental health conditions. Studies have reported a gap in treatment for mental health conditions in many countries in West Africa due to barriers along the access pathway. However, to the best of our knowledge, there is yet to be a review of the factors influencing access to primary care for common mental health conditions among adults in West Africa. OBJECTIVE: Our scoping review will explore the factors influencing access to primary care for common mental health conditions among adults aged 18 years and older in West Africa from 2002 to 2024. METHODS: Our review will follow the approach to scoping reviews developed by Arksey and O'Malley in 2005. This approach has five stages: (1) identifying the research question; (2) identifying relevant studies; (3) selecting studies; (4) charting the data; and (5) collating, summarizing, and reporting the results. We will search electronic databases (PubMed, Embase, PsycINFO, Cairn.info, and Google Scholar), source gray literature from relevant websites (the World Health Organization and country-specific websites), and manually explore reference lists of relevant studies to identify eligible records. Pairs of independent authors (NYA-B, RNBA, VR, or DS) will screen the titles, abstracts, and full texts of studies based on predefined eligibility criteria. We will use a data extraction tool adopted from the JBI Manual for Evidence Synthesis to chart the data. Deductive, thematic analysis will be used to categorize factors influencing access to mental health care under predetermined themes. New themes derived from the literature will also be charted. RESULTS: Database searches were conducted between February 1, 2024, and February 12, 2024. As of July 2024, the review report is being drafted, and it will be disseminated through publication in a peer-reviewed journal. CONCLUSIONS: The results of the review will inform decision-making on policies, programs, and their implementation in West Africa to improve primary care access for mental health care.

Phytotherapy in psychiatry: why psychiatrists should know about it.

There is a substantial use of Complementary and Alternative Medicine (CAM) among both the general population and psychiatric patients, with only a minority of these users disclosing this information to their healthcare providers, including physicians and psychiatrists. This widespread use of CAM can impact positively or negatively on the clinical outcomes of psychiatric patients, and it is often done along with conventional medicines. Among CAM, phytotherapy has a major clinical relevance due to the introduction of potential adverse effects and drug interactions. Thus, the psychiatrist must learn about phytotherapy and stay up-to-date with solid scientific knowledge about phytotherapeutics/herbal medicines to ensure optimal outcomes for their patients. Furthermore, questions about herbal medicines should be routinely asked to psychiatric patients. Finally, scientifically sound research must be conducted on this subject.

Frustrative Nonreward: Behavior, Circuits, Neurochemistry, and Disorders.

The surprising omission or reduction of vital resources (food, fluid, social partners) can induce an aversive emotion known as frustrative nonreward (FNR), which can influence subsequent behavior and physiology. FNR is an integral mediator of irritability/aggression, motivation (substance use disorders, depression), anxiety/fear/threat, learning/conditioning, and social behavior. Despite substantial progress in the study of FNR during the twentieth century, research lagged in the later part of the century and into the early twenty-first century until the National Institute of Mental Health's Research Domain Criteria initiative included FNR and loss as components of the negative valence domain. This led to a renaissance of new research and paradigms relevant to basic and clinical science alike. The COVID-19 pandemic's extensive individual and social restrictions were correlated with increased drug and alcohol use, social conflict, irritability, and suicide, all potential consequences of FNR. This article highlights animal models related to these psychiatric disorders and symptoms and presents recent advances in identifying the brain regions and neurotransmitters implicated.

Microstate Analyses to Study face Processing in Healthy Individuals and Psychiatric Disorders: A Review of ERP Findings.

Microstates represent brief periods of quasi-stable electroencephalography (EEG) scalp topography, offering insights into dynamic fluctuations in event-related potential (ERP) topographies. Despite this, there is a lack of a comprehensive systematic overview of microstate findings concerning cognitive face processing. This review aims to summarize ERP findings on face processing using microstate analyses and assess their effectiveness in characterizing face-related neural representations. A literature search was conducted for microstate ERP studies involving healthy individuals and psychiatric populations, utilizing PubMed, Google Scholar, Web of Science, PsychInfo, and Scopus databases. Twenty-two studies were identified, primarily focusing on healthy individuals (n = 16), with a smaller subset examining psychiatric populations (n = 6). The evidence reviewed in this study suggests that various microstates are consistently associated with distinct ERP stages involved in face processing, encompassing the processing of basic visual facial features to more complex functions such as analytical processing, facial recognition, and semantic representations. Furthermore, these studies shed light on atypical attentional neural mechanisms in Autism Spectrum Disorder (ASD), facial recognition deficits among emotional dysregulation disorders, and encoding and semantic dysfunctions in Post-Traumatic Stress Disorder (PTSD). In conclusion, this review underscores the practical utility of ERP microstate analyses in investigating face processing. Methodologies have evolved towards greater automation and data-driven approaches over time. Future research should aim to forecast clinical outcomes and conduct validation studies to directly demonstrate the efficacy of such analyses in inverse space.

The Implications of Sanctions on Civilian Mental Health and Quality of life Iranian: An overview.

BACKGROUND: The Islamic Republic of Iran has been under sanctions since 1979. These sanctions were further reinforced between the years 2005 and 2012. This study utilizes available data from Iran post-sanctions to review the impact of economic sanctions on both the mental health and the quality of life of Iranian citizens. METHODS: A comprehensive scoping review was conducted to identify studies examining the impact of sanctions on health in Iran. Searches were initiated in 2012 using PubMed/Medline, Embase, Web of Science, Scopus, and the Scientific Information Database (Iranian Database) with keywords such as sanctions, implications, mental health, quality of life, civilian mental health, and Iran. Subsequent to the screening process, secondary reports and letters to the editor were excluded. Only original studies-those collecting data via observation, interviews, surveys, experiments, or literature reviews-were retained for analysis. In addition to these search strategies, reference scanning was undertaken to identify additional articles pertinent to the scope of the current study. This thorough approach facilitated the discovery of relevant and significant articles exploring the effects of sanctions against Iran on the mental health and overall well-being of its civilian population. Following the search, duplicate articles were meticulously identified and removed by the authors. Data were subsequently extracted and summarized, focusing on study characteristics and the observed effects of sanctions on civilian mental health and quality of life in Iran. RESULT: Out of 165 items identified in the preliminary search, ten articles met the inclusion criteria. These selected articles highlighted the pronounced effects of sanctions on various health-related domains. CONCLUSION: Since 2012, Iran has been subject to intensified sanctions. There is evidence to suggest that the economic sanctions, imposed by Western nations, and have exerted a negative and detrimental impact on the health of individual Iranians.

The Holland Sleep Disorders Questionnaire: Factorial structure and measurement invariance in a psychiatric sample relative to the general population.

OBJECTIVES: Although common, sleep disorders often remain undiagnosed in psychiatric patients. A screening instrument, like the Holland Sleep Disorders Questionnaire (HSDQ) could improve this. Previous work indicated a 6-factor structure for the HSDQ, but this hasn't been investigated in psychiatric patients. METHODS: HSDQ data was collected in a psychiatric-outpatient sample (n = 1082) and general-population sample (n = 2089). Internal reliability of the HSDQ was investigated and Confirmatory Factor Analyses (CFA) were used to compare 1-, 6-, and second-order 6-factor models in both samples. Next, multigroup-CFA was used to investigate measurement invariance. RESULTS: Except for one subscale, internal reliability was acceptable in both samples. The 6-factor structure model fitted best in both samples and investigation of measurement invariance showed evidence for equality of the overall factor structure (configural invariance). Addition of equality constraints on factor loadings (metric invariance) and item thresholds (scalar invariance) showed good fit for all fit statistics, except for one. Exploratory analyses identified three items for metric and three different items for scalar invariance explaining this non-invariance. CONCLUSION: The HSDQ has a 6-factor structure in psychiatric patients, which is comparable to the general population. However, due to the observed non-invariance, users should be cautious with comparing HSDQ scores between psychiatric and general populations.

Clinical Use of Mental Health Digital Therapeutics in a Large Health Care Delivery System: Retrospective Patient Cohort Study and Provider Survey.

Background: While the number of digital therapeutics (DTx) has proliferated, there is little real-world research on the characteristics of providers recommending DTx, their recommendation behaviors, or the characteristics of patients receiving recommendations in the clinical setting. Objective: The aim of this study was to characterize the clinical and demographic characteristics of patients receiving DTx recommendations and describe provider characteristics and behaviors regarding DTx. Methods: This retrospective cohort study used electronic health record data from a large, integrated health care delivery system. Demographic and clinical characteristics of adult patients recommended versus not recommended DTx by a mental health provider between May 2020 and December 2021 were examined. A cross-sectional survey of mental health providers providing these recommendations was conducted in December 2022 to assess the characteristics of providers and recommendation behaviors related to DTx. Parametric and nonparametric tests were used to examine statistical significance between groups. Results: Of 335,250 patients with a mental health appointment, 53,546 (16%) received a DTx recommendation. Patients recommended to DTx were younger, were of Asian or Hispanic race or ethnicity, were female, were without medical comorbidities, and had commercial insurance compared to those without a DTx recommendation (P<.001). More patients receiving a DTx recommendation had anxiety or adjustment disorder diagnoses, but less had depression, bipolar, or psychotic disorder diagnoses (P<.001) versus matched controls not recommended to DTx. Overall, depression and anxiety symptom scores were lower in patients recommended to DTx compared to matched controls not receiving a recommendation, although female patients had a higher proportion of severe depression and anxiety scores compared to male patients. Provider survey results indicated a higher proportion of nonprescribers recommended DTx to patients compared to prescribers (P=.008). Of all providers, 29.4% (45/153) reported using the suggested internal electronic health record-based tools (eg, smart text) to recommend DTx, and of providers recommending DTx resources to patients, 64.1% (98/153) reported they follow up with patients to inquire on DTx benefits. Only 38.4% (58/151) of respondents report recommending specific DTx modules, and of those, 58.6% (34/58) report following up on the impact of these specific modules. Conclusions: DTx use in mental health was modest and varied by patient and provider characteristics. Providers do not appear to actively engage with these tools and integrate them into treatment plans. Providers, while expressing interest in potential benefits from DTx, may view DTx as a passive strategy to augment traditional treatment for select patients.

Mental health problems in pregnant and postpartum women living with HIV in sub-Saharan Africa: Systematic review and meta-analysis protocol.

BACKGROUND: Existing evidence on the burden of mental health problems among pregnant and postpartum women living with HIV, a vulnerable population in sub-Saharan Africa (SSA), is limited and fragmented, affecting the development of context-sensitive and integrated interventions. This systematic review aims to provide an up-to-date and comprehensive synthesis of available evidence to estimate the burden and identify the determinants of mental health problems among pregnant and postpartum women living with HIV across countries in sub-Saharan Africa. METHODS: We will retrieve all relevant studies (published and unpublished) through searches in PubMed, Embase, PsycINFO, CINAHL, LILACS, Google Scholar, Scopus and Web of Science from inception to 30th June 2024, without language restriction. We will use the following search terms 'mental health disorder', 'mental health problem', 'pregnant women', 'postpartum women' and 'HIV' nested with all applicable alternate terms and the names of countries in SSA for running the searches. We will also search HINARI, African Index Medicus, African Journals Online, Academic Search Premier, medRxiv, ProQuest, EBSCO Open Dissertations, and reference lists of relevant studies. We will contact experts in the field for potentially relevant unpublished studies. All retrieved articles from the electronic databases and grey literature will be collated and deduplicated using Endnote and exported to Rayyan QCRI. Two reviewers will independently select studies using a pretested study selection flow chart developed from the pre-specified eligibility criteria. Two reviewers will extract data using a pretested data extraction form and assess the risk of bias in the included studies using the risk of bias tool for prevalence studies by Hoy et al. (2012). Any disagreements will be resolved through discussion between the reviewers. Binary outcomes (prevalence and incidence of mental health problems among pregnant and postpartum women living with HIV) will be evaluated using pooled proportions (for non-comparative studies) and odds ratio (OR) or risk ratio (RR) (for comparative studies), and mean difference for continuous outcomes, all will be reported with their 95% confidence intervals (CIs). Heterogeneity will be assessed graphically for overlapping CIs and statistically using the I2 statistic. If substantial heterogeneity is found, random-effects model meta-analysis will be performed; otherwise, fixed-effect meta-analysis will be employed. We will conduct subgroup analysis (to assess the impact of heterogeneity) and sensitivity analyses to test the robustness of the generated effect estimates to the quality domains. The overall level of evidence will be assessed using GRADE (Grading of Recommendations, Assessment, Development, and Evaluations). EXPECTED OUTCOMES: The review is expected to produce an up-to-date and comprehensive synthesis of the available evidence, allowing for the generation of country-specific estimates of the burden of mental health problems among mothers living with HIV across SSA populations. Also, the review will attempt to identify the determinants of mental health problems among pregnant and postpartum women living with HIV, to shed light on the factors that contribute to the occurrence of mental health problems in this vulnerable population. SYSTEMATIC REVIEW REGISTRATION: The systematic review protocol has been registered in the International Prospective Register for Systematic Reviews (PROSPERO), with registration ID CRD42023468537.

X- vs. Y-chromosome influences on human behavior: a deep phenotypic comparison of psychopathology in XXY and XYY syndromes.

BACKGROUND: Do different genetic disorders impart different psychiatric risk profiles? This question has major implications for biological and translational aspects of psychiatry, but has been difficult to tackle given limited access to shared batteries of fine-grained clinical data across genetic disorders. METHODS: Using a new suite of generalizable analytic approaches, we examine gold-standard diagnostic ratings, scores on 66 dimensional measures of psychopathology, and measures of cognition and functioning in two different sex chromosome aneuploidies (SCAs)-Klinefelter (XXY/KS) and XYY syndrome (n = 102 and 64 vs. n = 74 and 60 matched XY controls, total n = 300). We focus on SCAs for their high collective prevalence, informativeness regarding differential X- vs. Y-chromosome effects, and potential relevance for normative sex differences. RESULTS: We show that XXY/KS elevates rates for most psychiatric diagnoses as previously reported for XYY, but disproportionately so for anxiety disorders. Fine-mapping across all 66 traits provides a detailed profile of psychopathology in XXY/KS which is strongly correlated with that of XYY (r = .75 across traits) and robust to ascertainment biases, but reveals: (i) a greater penetrance of XYY than KS/XXY for most traits except mood/anxiety problems, and (ii) a disproportionate impact of XYY vs. XXY/KS on social problems. XXY/KS and XYY showed a similar coupling of psychopathology with adaptive function and caregiver strain, but not IQ. CONCLUSIONS: This work provides new tools for deep-phenotypic comparisons of genetic disorders in psychiatry and uses these to detail unique and shared effects of the X- and Y-chromosome on human behavior.

The effect of legal representation on clinical measures in involuntarily admitted psychiatric patients: a retrospective study.

BACKGROUND: Most western countries provide funded legal representation (LR) for involuntarily admitted psychiatric patients appearing before judicial committees. In 2004, an amendment to the Israeli Mental Health Act granted this right to involuntarily committed psychiatric patients. Psychiatrists then voiced concerns that LR may increase rates of premature discharge and compromise patients' safety and well-being. These worries have not been sufficiently addressed to date. This study aimed to provide answers to their concerns. METHODS: This study included 3124 and 3434 inpatients involuntarily admitted to psychiatric facilities in 2000 and in 2010 (respectively), prior to and after the introduction of LR in Israel. Data were acquired from the Israeli National Psychiatric Hospitalization Registry. Clinical measures included percentage of discharges by the District Psychiatric Board (DPB), duration of involuntary hospitalization and rates of readmissions within thirty days and six months of discharge by treating psychiatrists (TP) or DPB. RESULTS: The odds ratio (OR) of discharge by a DPB in 2010 (n = 221) compared to 2000 (n = 93) was 2.2 [95%CI 1.72-2.82]. The OR was similar for readmissions within thirty days or six months among patients discharged by TP and a DPB (OR = 1.08, p = 0.697 and OR = 0.92, p = 0.603, respectively) as well as between the two time points (p = 0.486 and p = 0.618). The duration of hospitalizations terminated by a DPB was significantly shorter than those terminated by TP, with no difference between the study time points. The mean hospitalization duration in 2010 was 21% shorter compared to 2000 among patients discharged by TP. CONCLUSIONS: The number of DPB proceedings and the number of involuntarily hospitalized psychiatric patients discharged by DPBs increased considerably after the advent of state-funded legal representation in 2004. We found that this did not compromise beneficence and non-malfeasance of patient care. Our results emphasize the feasibility of affording even the most severely mentally ill patients the rights to due process. These findings may relieve concerns about state-funded LR procedures in involuntary psychiatric hospitalizations.
