RESUMO

The Criminal Sentiments Scale-Modified (CSS-M) has been widely used as a measure of criminal attitudes. This analysis examined CSS-M scores in a large sample of outpatients with serious mental illnesses and a criminal legal system history. We compared total and subscale scores in our sample to scores from two other previously published U.S. studies in which the CSS-M was used, and evaluated associations between total CSS-M score and nine variables (age, educational attainment, gender, race, marital status, employment status, diagnostic category, substance use disorder comorbidity, and adverse childhood experiences (ACE) score). Scores were higher than in two prior U.S. studies involving other types of samples. Independently significant predictors of higher CSS-M scores included being younger (P < .001), having a higher ACE score (P < .001), being male (P = 03), not identifying as White (P < 001), not having a psychotic disorder (P < 001), and having a comorbid substance use disorder (P = 002). Future research should test the hypothesis that these factors increase risk for arrest and that arrest events, and subsequent criminal legal system involvement, are characterized by negative experiences and perceptions of poor procedural justice, which in turn underpin the negative opinions referred to as "criminal sentiments" or criminal attitudes.

RESUMO

OBJECTIVE: Acoustic phonetic measures have been found to correlate with negative symptoms of schizophrenia, thus offering a path toward quantitative measurement of such symptoms. These acoustic properties include F1 and F2 measurements (affected by tongue height and tongue forward/back position, respectively), which determine a general "vowel space." Among patients and controls, we consider two phonetic measures of vowel space: average Euclidean distance from a participant's mean F1 and mean F2, and density of vowels around one standard deviation of mean F1 and of F2. METHODS: Structured and spontaneous speech of 148 participants (70 patients and 78 controls) was recorded and measured acoustically. We examined correlations between the phonetic measures of vowel space and ratings of aprosody obtained using two clinical research measures, the Scale for the Assessment of Negative Symptoms (SANS) and the Clinical Assessment Interview for Negative Symptoms (CAINS). RESULTS: Vowel space measurements were significantly associated with patient/control status, attributed to a cluster of 13 patients whose phonetic values correspond to reduced vowel space as assessed by both phoenetic measures. No correlation was found between phonetic measures and relevant items and averages of ratings on the SANS and CAINS. Reduced vowel space appears to affect only a subset of patients with schizophrenia, potentially those on higher antipsychotic dosages. CONCLUSIONS: Acoustic phonetic measures may be more sensitive measures of constricted vowel space than clinical research rating scales of aprosody or monotone speech. Replications are needed before further interpretation of this novel finding, including potential medication effects.

RESUMO

Objective: Opening Doors to Recovery (ODR) is a community navigation and recovery support model created in southeast Georgia by diverse, collaborative stakeholders. Following promising results from a quasi-experimental study, this randomized controlled trial hypothesized that, among patients with serious mental illnesses being discharged from inpatient psychiatric settings, compared to those randomized to traditional case management (CM) services, those randomized to ODR would have (1) lower likelihood of hospitalization, fewer hospitalizations, and fewer inpatient days; (2) lower likelihood of arrest, fewer arrests, and longer time to arrest; and, secondarily, (3) greater housing satisfaction and housing stability; and (4) higher scores on several scales measuring recovery-related constructs.Methods: 240 individuals with Structured Clinical Interview for DSM-5 Disorders-based psychotic or mood disorders, functional impairment, and repeated hospitalizations were randomized (December 2014 to June 2018) to ODR or CM. Hospitalization and arrest data were collected from State agencies after 12 months, and housing- and recovery-related measures were collected in person, longitudinally at 4, 8, and 12 months. Intention-to-treat analyses were conducted. Effects of dropout were accounted for, and sensitivity analyses were run.Results: ODR was associated with fewer days hospitalized (RR = 0.86, P = .001), a lower incidence of arrests (OR = 0.35, P < .0005), and longer time to arrest (HR = 0.42, P = .001). In addition, measures of housing satisfaction (Cohen d = 0.45) and recovery (Cohen d = 0.33) were significantly more improved in ODR patients compared to CM patients.Conclusions: The ODR model appears to have advantages over more traditional CM services and could fill a gap in the service array. Studying the mediators of success, cost benefit, dissemination, fidelity, and financing of the model is warranted.Trial Registration: ClinicalTrials.gov identifier: NCT04612777.

RESUMO

There is a sparse literature on women who hear voices globally, even though there are documented gendered dimensions of distress in the context of globalization and climate change and research indicates that trauma and psychosocial stress may be related to an increased prevalence of voice-hearing or auditory verbal hallucinations (AVHs). There is also a gap in the cultural phenomenology of voice-hearing in general, as well as idioms of distress for non-western peoples. This article presents results of a mixed methods study that: 1) estimated community prevalence of voice-hearing among Maasai women in northern Tanzania; 2) examined any demographic correlates and two specific hypothesized correlates (i.e., psychological stress and potentially traumatic events); and 3) engaged women in semi-structured interviews about their everyday lives and the phenomenological experience of voice-hearing. The prevalence of voice-hearing (39.4%) in this nonclinical sample (n = 71) was quite high compared to other studies in sub-Saharan Africa. Most women also reported high psychosocial stress and traumatic life events. They also talked about gendered conditions of social adversity in a context of rapid social, economic, and climate change. Women who reported hearing voices had a statistically significantly higher level of psychological distress, met criteria for severe psychological distress, and reported more potentially traumatic life events. In a logistic regression model, psychosocial stress predicted voice-hearing. The presence of distressing voices may offer a straightforward way to quickly identify people in the community experiencing the most extreme levels of psychosocial stress and traumatic events-a potentially simple but effective screening tool for health workers on the ground.

RESUMO

Objective: Individuals with serious mental illnesses are overrepresented in all facets of the legal system. State-level criminal histories of patients with serious mental illnesses were analyzed to determine the proportion who had been arrested and number of lifetime arrests and charges, associations of six variables with number of arrests, and the most common charges from individuals' first two arrests and most recent two arrests. Methods: A total of 240 patients were recruited at three inpatient psychiatric facilities and gave consent to access their criminal history. Information was extracted from Record of Arrest and Prosecution (RAP) sheets for lifetime arrests in Georgia. Results: A total of 171 (71%) had been arrested. Their mean±SD lifetime arrests were 8.6±10.1, and mean lifetime charges were 12.6±14.6. In a Poisson regression, number of arrests was associated with lower educational attainment, Black or African American race, the presence of a substance use disorder, the presence of a mood disorder, and female sex. Common early charges included marijuana possession, driving under the influence of alcohol, and burglary and shoplifting. Common recent charges included probation violations, failure to appear in court, officer obstruction­related charges, and disorderly conduct. Conclusions: Findings point to a need for policy and program development in the legal system (e.g., pertaining to charges such as willful obstruction of an officer), the mental health community (e.g., to ensure that professionals know about clients' legal involvement and can partner in strategies to reduce arrests), and social services sectors (to address charges, such as shoplifting, often related to material disadvantage).

RESUMO

BACKGROUND: Radiofrequency ablation has been shown to be a safe and effective treatment for scar-related ventricular arrhythmias (VA). Recent preliminary studies have shown that real time integration of late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) images with electroanatomical map (EAM) data may lead to increased procedure efficacy, efficiency, and safety. METHODS: VOYAGE is a prospective, randomized, multicenter controlled open label study designed to compare in terms of efficacy, efficiency, and safety a CMR aided/guided workflow to standard EAM-guided ventricular tachycardia (VT) ablation. Patients with an ICD or with ICD implantation expected within 1 month, with scar related VT, suitable for CMR and multidetector computed tomography (MDCT) will be randomized to a CMR-guided or CMR-aided approach, whereas subjects unsuitable for imaging or with image quality deemed not sufficient for postprocessing will be allocated to standard of care ablation. Primary endpoint is defined as VT recurrences (sustained or requiring appropriate ICD intervention) during 12 months follow-up, excluding the first month of blanking period. Secondary endpoints will include procedural efficiency, safety, impact on quality of life and comparison between CMR-guided and CMR-aided approaches. Patients will be evaluated at 1, 6 and 12 months. DISCUSSION: The clinical impact of real time CMR-guided/aided ablation approaches has not been thoroughly assessed yet. This study aims at defining whether such workflow results in more effective, efficient, and safer procedures. If proven to be of benefit, results from this study could be applied in large scale interventional practice. Trial registrationClinicalTrials.gov, NCT04694079, registered on January 1, 2021.

RESUMO

While genetic factors play a critical role in the risk for schizophrenia and other psychotic disorders, increasing evidence points to the role of childhood adversity as one of several environmental factors that can significantly impact the development, manifestations and outcome of these disorders. This paper reviews the epidemiological evidence linking childhood adversity and psychotic disorders and explores various theoretical models that seek to explain the connection. We discuss neurobiological parallels between the impact of childhood trauma and psychosis on the brain and then explore the impact of childhood adversity on different domains of clinical presentation. Finally, implications for prevention and treatment are considered, both on individual and structural levels.

RESUMO

Automated tools do not yet exist to measure formal thought disorder, including derailment and tangentiality, both of which can be subjectively rated using the Scale for the Assessment of Positive Symptoms after a clinical research interview. CoVec, a new automated tool, measures the semantic similarity among words averaged in a five- and ten-word window (Coherence-5 and Coherence-10, respectively). One prior report demonstrated that this tool was able to differentiate between patients with those types of thought disorder and patients without them (and controls). Here, we attempted a replication of the initial findings using data from a different sample of patients hospitalized for initial evaluation of first-episode psychosis. Participants were administered a semantic fluency task and the animal lists were analyzed with CoVec. In this study, we partially replicated the prior findings, showing that first-episode patients with derailment had significantly lower Coherence-5 and Coherence-10 compared with patients without derailment. Further research is warranted on this and other highly reliable and objective methods of detecting formal thought disorder through simple assessments such as semantic fluency tasks.

RESUMO

AIM: Although the absolute risk of violence is small for individuals with mental illnesses, a specific subgroup of individuals who appear to be at increased risk for violence includes young people experiencing emerging or early psychosis. Prior research has identified risk factors for violence in this population, though no prior studies using a formal risk assessment tool have been identified. This study used the Historical Clinical Risk Management-20, version 3 (HCR-20) to identify risk of future violence among a sample of young adults with early psychosis and relevant predictors of risk unique to this population. METHODS: The HCR-20 was administered to a sample of young adults with early psychosis (N = 53) enrolled at one OnTrackNY site, part of a statewide program providing early intervention services to young adults presenting with a first episode of non-affective psychosis. A Confirmatory Factor Analysis (CFA) was conducted to explore the relative importance of the HCR-20 items for this population. RESULTS: The average age of participants was 21.9 years (SD 3.6 years) and most were male (69.8%, n = 37). Most patients were assessed to be at low risk for future violence based on the Case Prioritization summary risk rating (67.9%, n = 36). The CFA identified 4 items that were not of relative predictive value in identifying the risk of violence in this sample: history of substance use (item H5), history of major mental disorder (item H6), living situation (item R2), and personal support (item R3). CONCLUSION: This study presents a formal approach to assessing violence risk in a population at elevated risk of violence, demonstrates the feasibility of using a standardized risk assessment tool in early intervention services, and identifies factors of particular importance associated with predicting violence in this population. Future research should implement violence risk assessment with a structured tool such as the HCR-20 and assess its accuracy in predicting future violent behavior in this setting.

RESUMO

BACKGROUND: Despite the benefits of early intervention services for the initial stages of psychosis ongoing impairments in functioning are common. AIMS: To identify 1-year trajectories of occupational and social functioning in individuals enrolled in OnTrackNY, a statewide program offering early intervention services for recent-onset psychosis in community settings. METHOD: We included 937 persons with recent-onset psychosis enrolled at 19 programs across New York State. Demographic, social and clinical data was collected at program entry and at 3, 6, 9 and 12 months. We used growth mixture models to identify occupational and social functioning trajectories and examined the association between trajectory class, baseline factors and symptoms during 1-year follow-up. RESULTS: Four distinct trajectory classes of occupational and social functioning were identified. The converging (58.0%) class had disparate levels of functioning at baseline (low occupational, higher social) which eventually converged. The other classes had high-stable (14.8%), moderate-stable (17.8%) and low-improving (9.4%) trajectories. Female gender, educational attainment and private insurance status were significantly associated with the trajectory characterized by higher functioning, while living alone, homelessness, a longer period from psychosis onset to program enrollment, a schizophrenia diagnosis and cannabis use at enrollment were associated with the poorest trajectory. The differences in severity of symptoms by trajectory class diminished over time. CONCLUSIONS: Trajectories of occupational and social functioning showed substantial variation, but overall, remained stable or improved during 1-year follow-up. The relationship between symptoms and occupational and social functioning attenuated after the acute treatment phase.

RESUMO

Hope and empowerment are key elements of recovery in the context of serious mental illnesses (SMI). We examined predictors of hope among individuals with SMI and tested a hypothesized path model in which perceived social status and perceived discrimination adversely impact hope, directly and through their impacts on depressive symptoms. Data from 232 individuals with SMI receiving care in public-sector settings were used in both a multiple linear regression (predicting Herth Hope Scale scores), and in path analyses examining both direct and indirect effects of perceived social status (Social Status Ladder) and perceived discrimination (Everyday Discrimination Scale). Depressive symptoms, perceived social status, and perceived discrimination were predictive of hope. Path analyses revealed that perceived social status has a direct effect on hope and empowerment but also impacts hope through its effects on depression. Similarly, perceived everyday discrimination affects hope and empowerment, though this effect is mediated through its effects on depression. Two alternative models and a trimmed hypothesized model did not fit the data or improve fit. These social determinants of mental health should provoke program and policy change to improve mental health and enhance recovery among persons with SMI.

RESUMO

OBJECTIVE: Recent years have witnessed growing interest in the role of the social environment in the development and outcomes of schizophrenia. We investigated whether neighborhood characteristics are associated with two important prognostic factors in early-course psychosis, age at onset of psychosis (AOP) and duration of untreated psychosis (DUP). METHODS: Data were collected from patients admitted to the hospital for first-episode schizophrenia-spectrum disorder. We collected data on perceived neighborhood disorder during childhood/adolescence and extracted data on 13 neighborhood characteristics from the American Community Survey based upon individual addresses. Four neighborhood-level factors were derived from factor analysis. Multiple logistic regression analyses assessed the association between specific neighborhood characteristics and the two prognostic factors (earlier AOP and longer DUP) in early-course psychosis. RESULTS: 143 participants had valid addresses geo-coded. Neighborhood-level residential instability was associated with an earlier AOP (OR = 1.760; p = 0.022) even after controlling for known risk factors (OR = 2.026; p = 0.020) and also after controlling for individual-level residential instability (OR = 1.917; p = 0.037). The general socioeconomic status neighborhood factor (OR = 1.119; p = 0.019) and perceived neighborhood disorder (OR = 1.075; p = 0.005) were associated with a longer DUP. But only perceived neighborhood disorder (OR = 1.146; p = 0.011) remained significant, and general socioeconomic status was close to significant (OR = 1.215; p = 0.062), after controlling for individual-level predictors and socioeconomic status. CONCLUSIONS: This study found evidence that neighborhood-level characteristics (in this case, residential instability) may be associated with earlier AOP, and perceptions of neighborhood disorder are associated with a longer treatment delay. Socioenvironmental factors should be more consistently considered going forward in research on early psychotic disorders.

RESUMO

As mental health services are increasingly embracing the recovery model, we conducted a study to better understand how social adversity impacts recovery. We also examined how associations between social adversity and recovery are influenced (moderated or mediated) by symptom severity. Data on seven social adversity measures, eight recovery measures, and symptom severity were collected from 300 English-speaking participants, ages 18-65 years, with a diagnosis of a psychotic or mood disorder, from five community mental health agencies in diverse neighborhoods in Washington, D.C. We employed standard correlation, exploratory factor analyses, analysis of variance, and hierarchic regression procedures. Diagnostic category and gender impacted Home Environment Adversities (e.g., food insecurity, perceived neighborhood disorder), the diagnostic category-by-gender interaction influenced Social and Economic Adversities (e.g., years of education and income), and gender affected Recovery. Controlling for diagnostic category and gender, Social and Economic Adversities accounted for 1.7% of variance in Recovery, while Home Environment Adversities accounted for 8.6% (their joint influence was 3.4%). Although symptom severity did not moderate these associations, it partially mediated the effect of Social and Economic Adversities on Recovery, and substantially mediated the effect of Home Environment Adversities on Recovery. The extent to which patients with serious mental illnesses experience recovery may be meaningfully influenced not only by symptoms, but by their social and environmental circumstances.

RESUMO

OBJECTIVE: This study aimed to evaluate the effectiveness of Homefront, a six-session, peer-taught family education program by the National Alliance on Mental Illness (NAMI), delivered in person or online, for families or support persons of military service members or of veterans with mental illness. METHODS: Program participants completed online surveys at baseline, at the end of the program (postprogram), and at 3-month follow-up, which measured subjective empowerment, burden, coping, psychological distress, family functioning, experience of caregiving, and knowledge of mental illness. A mixed-effects model examined change over time. RESULTS: A total of 119 individuals (in person, N=63 [53%]; online, N=56 [47%]) enrolled. Participants showed statistically significant improvement on all dimensions between baseline, postprogram, and follow-up, except for subjective burden, which improved between baseline and follow-up. Results for in-person and online formats did not differ. CONCLUSIONS: The six-session NAMI Homefront program was associated with benefits for military and veteran family members and support persons.

RESUMO

AIM: The Cannabis Experiences Questionnaire (CEQ) was developed to measure the subjective experiences of cannabis use both during and after intoxication. Despite the need to better understand the nature of the complex and significant relationship between cannabis use and early psychosis, this questionnaire has rarely been used in individuals with first-episode psychosis. METHODS: We conducted a set of factor analyses using CEQ data from 194 first-episode psychosis patients who used cannabis in order to uncover the underlying factor structure of the questionnaire and thus the overarching types of psychological experiences during/after using cannabis in young people with psychotic disorders. RESULTS: Our exploratory factor analysis identified 4 subscales, including: Distortions of Reality and Self-Perception (Factor 1), Euphoria Effects (Factor 2), Slowing and Amotivational Effects (Factor 3), and Anxiety and Paranoia Effects (Factor 4). CONCLUSIONS: Elucidating the underlying factor structure of the CEQ in first-episode psychosis samples could help researchers move towards a deeper understanding of the types of experiences associated with cannabis intoxication among young adults with first-episode psychosis and could inform the development of programs designed to reduce use, improve the course of illness, and possibly delay or prevent the onset of psychotic symptoms in those at risk.

RESUMO

Although rating scales to assess formal thought disorder exist, there are no objective, high-reliability instruments that can quantify and track it. This proof-of-concept study shows that CoVec, a new automated tool, is able to differentiate between controls and patients with schizophrenia with derailment and tangentiality. According to ratings from the derailment and tangentiality items of the Scale for the Assessment of Positive Symptoms, we divided the sample into three groups: controls, patients without formal thought disorder, and patients with derailment/tangentiality. Their lists of animals produced during a one-minute semantic fluency task were processed using CoVec, a newly developed software that measures the semantic similarity of words based on vector semantic analysis. CoVec outputs were Mean Similarity, Coherence, Coherence-5, and Coherence-10. Patients with schizophrenia produced fewer words than controls. Patients with derailment had a significantly lower mean number of words and lower Coherence-5 than controls and patients without derailment. Patients with tangentiality had significantly lower Coherence-5 and Coherence-10 than controls and patients without tangentiality. Despite the small samples of patients with clinically apparent thought disorder, CoVec was able to detect subtle differences between controls and patients with either or both of the two forms of disorganization.

RESUMO

OBJECTIVE: We identified, in subjects with first-episode psychosis, demographic and socioenvironmental predictors of three variables pertaining to premorbid marijuana use: age at initiation of marijuana use, trajectories of marijuana use in the five years prior to onset of psychosis, and the cumulative "dose" of marijuana intake in that same premorbid period. METHODS: We enrolled 247 first-episode psychosis patients and collected data on lifetime marijuana/alcohol/tobacco use, age at onset of psychosis, diverse socioenvironmental variables, premorbid adjustment, past traumatic experiences, perceived neighborhood-level social disorder, and cannabis use experiences. Bivariate tests were used to examine associations between the three premorbid marijuana use variables and hypothesized predictors. Regression models determined which variables remained independently significantly associated. RESULTS: Age at initiation of cigarette smoking was linked to earlier initiation, faster escalation, and higher cumulative dose of premorbid marijuana use. During childhood, poorer academic performance was predictive of an earlier age at initiation of marijuana use, while poorer sociability was related to more rapid escalation to daily use and a higher cumulative dose. As expected, experiencing euphoric effects was positively correlated with trajectories and cumulative dose, but having negative experiences was unrelated. Traumatic childhood/adolescent experiences were correlated with rapid escalation and amount of marijuana used, but not with age at initiation of marijuana use. CONCLUSION: These data expand the very limited literature on predictors of premorbid marijuana use in first-episode psychosis. Given its association with earlier age at onset of psychosis, and poorer outcomes among first-episode patients, prevention and treatment efforts should be further developed.

RESUMO

OBJECTIVE: Acoustic phonetic methods are useful in examining some symptoms of schizophrenia; we used such methods to understand the underpinnings of aprosody. We hypothesized that, compared to controls and patients without clinically rated aprosody, patients with aprosody would exhibit reduced variability in: pitch (F0), jaw/mouth opening and tongue height (formant F1), tongue front/back position and/or lip rounding (formant F2), and intensity/loudness. METHODS: Audiorecorded speech was obtained from 98 patients (including 25 with clinically rated aprosody and 29 without) and 102 unaffected controls using five tasks: one describing a drawing, two based on spontaneous speech elicited through a question (Tasks 2 and 3), and two based on reading prose excerpts (Tasks 4 and 5). We compared groups on variation in pitch (F0), formant F1 and F2, and intensity/loudness. RESULTS: Regarding pitch variation, patients with aprosody differed significantly from controls in Task 5 in both unadjusted tests and those adjusted for sociodemographics. For the standard deviation (SD) of F1, no significant differences were found in adjusted tests. Regarding SD of F2, patients with aprosody had lower values than controls in Task 3, 4, and 5. For variation in intensity/loudness, patients with aprosody had lower values than patients without aprosody and controls across the five tasks. CONCLUSIONS: Findings could represent a step toward developing new methods for measuring and tracking the severity of this specific negative symptom using acoustic phonetic parameters; such work is relevant to other psychiatric and neurological disorders.

RESUMO

The aim of this cross-sectional study was to assess factors associated with client satisfaction in two mental health outpatient settings in Italy and the US. Sociodemographic and clinical variables, hope, and personality characteristics were evaluated in 18-65-year-old patients who had been receiving services for at least 2 months in one of two outpatient clinics, in Italy and the US. Patients were administered: the Healthy Days Core Module, the Kessler Screening Scale for Psychological Distress, the Verona Service Satisfaction Survey, the Client Satisfaction Inventory, the Health Service OutPatient Experience questionnaire, the Herth Hope Index, and the NEO Five-Factor Inventory-3. Bivariate tests for differences between the two samples were conducted, a Satisfaction Composite z-score was computed, and a stepwise, backward elimination, multiple linear regression model-including the variables that were significantly associated with Satisfaction Composite Score in bivariate tests-was built. From July 1, 2015 to April 30, 2016, 184 patients (121 in Foligno, 63 in New York City) were enrolled in the study. Predictors of client satisfaction included: receiving services in New York City, being older, having lower educational attainment, having inner positive readiness and expectancy as well as interconnectedness with self and others, and high scores on the agreeableness personality domain. Interestingly, diagnosis and treatment characteristics did not influence satisfaction. Client satisfaction with outpatient mental health services is mainly influenced by sociodemographic characteristics and personality factors more than clinical variables or patterns of care. These findings could have implications regarding trends toward value-based payment models.
