Interpersonal consequences of paranoid ideation, negative symptoms and sleep problems in a transdiagnostic sample of individuals with psychosis.

Paranoid ideation is a transdiagnostic construct that is associated with social impairment and often occurs in psychotic spectrum disorders. Little research has examined how paranoid ideation is related to social behaviors that underlie social impairment and may ultimately lead to social rejection. It is important to consider that negative symptoms and sleep problems also contribute to social impairment. No research has assessed the unique and combined influence of paranoid ideation, negative symptoms, and sleep problems on social impairment. Therefore, the current study examined how paranoid ideation, negative symptoms, and sleep problems contribute to poorer social skills and social rejection in a transdiagnostic sample of persons with psychosis and community members (N = 112). Assessments included diagnostic and symptom interviews, questionnaires, behavioral ratings of social skill and facial displays of affect, and naive observer reactions utilizing thin-slice methodology. Greater paranoid ideation, negative symptoms, and sleep problems were each related to poorer social skill and more negative reactions from observers. When considered in path analyses, negative symptoms were associated with observer reports of less willingness to interact with participants through poorer social skill. These findings demonstrate the symptom correlates of social rejection and how interpersonal behavior may contribute to social exclusion.

From Rhetoric to Action: Justice, Equity, Diversity, and Inclusion in Coordinated Specialty Care for Early Psychosis.

Attention to inclusivity and equity in health research and clinical practice has grown in recent years; however, coordinated specialty care (CSC) for early psychosis lags in efforts to improve equity despite evidence of ongoing disparities and inequities in CSC care. This Open Forum argues that marginalization and disparities in early psychosis research and clinical care are interrelated, and the authors provide suggestions for paths forward. Commitment to equity and justice demands recentering the perspectives of those most affected by early psychosis services and investing in the integration of historically excluded perspectives across all aspects of practice, policy, and research.

The impact of chronic pain and depression on medication for opioid use disorder treatment: A mixed-methods analysis.

Background: Opioid use disorder (OUD) is associated with significant morbidity and mortality. Medication for opioid use disorder (MOUD) is a cost-effective treatment, but retention rates vary widely. Aim: Mixed methods studies are needed to better understand how depression and pain impact the experience of OUD and MOUD treatment experiences. Methods: Participants were recruited from an urban addiction treatment center in the United States. Along with demographic characteristics, current pain severity, pain interference, pain catastrophizing, and depression were assessed via self-report. Correlational analyses, multivariable logistic regression models, Fisher exact tests, and Wilcoxon signed rank tests were used to examine the impact of demographic characteristics, physical pain, and depression on multiple treatment outcomes: 90-day treatment engagement (total number of dispensed MOUD doses), retention (yes/no still in treatment at 90 days), and opioid use (positive/negative urinalysis for opioids at 90 days). Ten participants were interviewed about their history with physical pain, depression, opioid use, and OUD treatment experiences. Themes were identified using a rapid analysis, top-down approach. Results: Fifty participants enrolled in the study and received buprenorphine (12%) or methadone (88%). Older age was associated with 90-day treatment engagement. Higher depression scores were associated with a positive opioid urinalysis at 90-day follow-up. In interviews, participants reported experiencing chronic physical pain and depression before and during their OUD and an interest in addressing mental and physical health in addiction treatment. Conclusions: Addressing co-occurring physical and mental health concerns during MOUD treatment has the potential to improve the treatment experience and abstinence from opioids.

Reasons for Discharge in a National Network of Early Psychosis Intervention Programs.

BACKGROUND: Discharge from early psychosis intervention is a critical stage of treatment that may occur for a variety of reasons. This study characterizes reasons for discharge among participants in early psychosis intervention programs participating in the Early Psychosis Intervention Network (EPINET) which comprises >100 programs in the United States organized under 8 academic hubs. STUDY DESIGN: We analyzed 1787 discharges, focusing on program completion, unilateral termination by the client/family, and lost contact with the client/family. We performed exploratory analyses of demographic, clinical, and functional predictors of discharge reason. Variables predictive of discharge type were included in multilevel logistic regressions, allowing for the estimation of predictors of discharge reason and variability in rates by program and hub. STUDY RESULTS: An estimated 20%-30% of enrolled patients completed the program. Program completion rates were higher among participants who were older on admission, had lower negative symptoms severity, spent more time in education, employment, or training, and who were covered by private insurance (a close proxy for socioeconomic status). Programs were more likely to lose contact with male participants, Black participants, and participants who were never covered by private insurance. After accounting for patient-level factors, there was substantial program-level variation in all 3 discharge outcomes, and hub-level variability in the proportion of participants who completed the program. The impact of race on program completion varied substantially by program. CONCLUSIONS: Participants were discharged from early psychosis intervention services for diverse reasons, some of which were associated with sociocultural factors. Disengagement is a widespread problem affecting all hubs.

Tobacco smoking and nicotine vaping in persons with first episode psychosis.

Tobacco smoking is highly prevalent in persons with psychosis and is the leading cause of preventable mortality in this population. Less is known about tobacco smoking in persons with first episode psychosis (FEP) and there have been no estimates about the prevalence of nicotine vaping in FEP. This study reports rates of tobacco smoking and nicotine vaping in young people with FEP enrolled in Coordinated Specialty Care programs in Pennsylvania and Maryland. Using data collected from 2021 to 2023, we examined lifetime and recent smoking and vaping and compared smokers and vapers to nonusers on symptoms, functioning, and substance use. The sample included 445 participants aged 13-35 with recent psychosis onset. Assessments were collected by program staff. Overall, 28 % of participants engaged in either smoking or vaping within 30 days of the admission assessment. Smokers and vapers were disproportionately male, cannabis users, and had lower negative symptom severity than non-smokers. Vapers had higher role and social functioning. Both smoking and vaping were related to a longer time from psychosis onset to program enrollment. We compare these findings to previous studies and suggest steps for addressing smoking and vaping in this vulnerable population.

The impact of the COVID-19 pandemic on perceptions of social relationships, negative affect, and paranoid ideation.

The COVID-19 pandemic contributed to worsening mental health across the globe. The pandemic may have been especially impactful on those experiencing heightened psychosis spectrum symptomatology given greater pre-pandemic social isolation and increased vulnerability to stress. Yet, few studies exploring the impact of the COVID-19 pandemic on perceptions of social relationships and mental health have sampled individuals high in psychosis spectrum symptomatology, including those with psychosis spectrum disorders. Utilizing a mixed transdiagnostic community sample enriched for psychotic spectrum disorders, this longitudinal study investigated whether perceptions of social relationships and psychiatric symptoms changed during the COVID-19 pandemic, whether pandemic-related impacts were associated with social perceptions and symptomatology, and whether paranoid ideation was related to perceptions of the government response to the COVID-19 pandemic. Pandemic impacts were not uniform, with participants reporting a range of adverse impacts including poorer health-related behaviors, difficulties fulfilling basic needs, and medical related challenges. Results indicated that compared to pre-pandemic assessments, perceived rejection and hostility increased during the COVID-19 pandemic. Participants who experienced more pandemic-related impacts reported less social support, more social distress, greater negative affect, and greater paranoid ideation. Paranoid ideation was related to more negative perceptions of the government's response to the pandemic. These findings demonstrate the importance of assessing individual differences in pandemic-related impacts and the clinical consequences of such impacts. Results also suggest that those high in paranoid ideation may be reluctant to engage in government recommended protective health behaviors to limit the spread of COVID-19.

A reduction in cigarette smoking improves health-related quality of life and does not worsen psychiatric symptoms in individuals with serious mental illness.

INTRODUCTION: Individuals with serious mental illness (SMI) smoke cigarettes at a much higher rate than the general population, increasing their risk for medical illnesses and mortality. However, individuals with SMI do not get enough support to quit smoking, partially because of concerns from medical providers that reducing smoking may worsen their symptoms or quality of life. METHODS: Veterans with SMI and nicotine dependence (n = 178) completed a 12-week smoking cessation trial (parent trial dates: 2010-2014) including assessments of smoking status, psychiatric symptoms (Brief Psychiatric Rating Scale), and quality of life (Lehman Quality of Life Interview-Short Version) at up to four time points: baseline, post-treatment, three-month follow-up, and 9-month follow-up. Bayesian multilevel modeling estimated the impact of changes in the self-reported number of cigarettes per day in the past seven days on psychiatric symptoms and quality of life. RESULTS: Between subjects, each additional pack of cigarettes smoked per day was associated with a 0.83 point higher score (95%CI: 0.03 to 1.7) on a negative symptoms scale ranging from 0 to 35. Within subjects, each one-pack reduction in the number of cigarettes smoked per day was associated with an improvement of 0.32 (95%CI = 0.12 to 0.54) on the health-related quality of life scale, which ranges from 0 to 7 points. There were no other significant between- or within-subjects effects of smoking on psychiatric symptoms or quality of life. CONCLUSIONS: Individuals with SMI and their providers should pursue smoking cessation without fear of worsening psychiatric symptoms or quality of life.

Associations among Trauma Exposure, Post-Traumatic Stress Symptoms and Alcohol Use in Black/African American Treatment-Seeking Adults.

OBJECTIVE: Black/African American (AA) individuals are a group at risk for co-occurring posttraumatic stress disorder (PTSD) symptoms and alcohol use due to unique cultural and system-level barriers. Although associations between trauma exposure, PTSD symptoms, and alcohol use are well established across various populations, Black/AA individuals are underrepresented in this literature, and related findings in this population are inconclusive. Thus, the goal of this study was to examine the associations among trauma exposure, PTSD symptoms, and alcohol use in a sample of treatment-seeking, Black/AA adults. We hypothesized that trauma exposure and alcohol use would be positively associated and that this relationship would be mediated by PTSD symptoms. METHODS: This study conducted secondary analysis of screening data from a PTSD and alcohol use disorder clinical trial. Participants were 96 Black/AA adults (57.3% male; 2.0% Hispanic; M age = 44.73, SD = 11.83) who were seeking treatment for alcohol use and endorsed trauma exposure. Associations between trauma exposure, PTSD symptom severity, and quantity and frequency of alcohol use were tested using bivariate correlations and linear regressions. Hypothesized indirect effects were tested using IBM SPSS Statistics Version 27 PROCESS model 4 with bootstrapping. RESULTS: Findings illustrated a significant positive association between trauma exposure and PTSD symptoms and between PTSD symptoms and drinks per typical drinking day. PTSD symptoms were not significantly associated with number of drinking days. Tests of indirect effects were significant for trauma exposure on drinks per typical drinking day through PTSD symptoms. CONCLUSIONS: Results from the test of indirect effects suggest that among Black/AA adults with heavy alcohol use and trauma exposure, trauma exposure is associated with PTSD symptoms, which in turn is associated with quantity of alcohol use. These findings are consistent with research conducted with White/mixed groups and align with tenets of the self-medication model of PTSD-AUD comorbidity. These findings support current practices that highlight the importance of screening for and addressing PTSD and alcohol use in individuals exposed to trauma. Findings from this paper provide initial data on understudied relationships in an underserved sample and several suggestions are made to generate future research and improve clinical care for Black/AA adults.

Increasing community engagement: Skills used by adults with schizophrenia participating in a psychosocial intervention.

OBJECTIVE: We present findings from a qualitative study aimed at understanding the experiences of Veterans with schizophrenia and negative symptoms who participated in trial of an intervention to increase social and community participation called Engaging in Community Roles and Experiences (EnCoRE). Our goal was to understand what participants (N = 36) perceived they learned in EnCoRE, how participants used what they learned in their daily lives, and if and how participants built on these experiences in ways that might lead to sustained change. METHOD: Our analysis approach was inductive (bottom up), drawing on interpretive phenomenological analysis (IPA; Conroy, 2003), plus some top-down examination of the role of EnCoRE elements in participants' accounts. RESULTS: We identified three themes: (a) Learning skills led to increased comfort talking to people and planning activities; (b) Increased comfort led to increased confidence to try new things; and (c) The group atmosphere offered support and accountability that helped participants practice and refine new skills. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The process of learning skills, planning to use them, implementing them, and returning to the group for input helped many surmount feelings of low interest and low motivation. Our findings support having proactive discussions with patients about how building confidence can support improved social and community participation.

Increasing social and community participation in veterans living with schizophrenia: A treatment outcome study.

People living with schizophrenia often face challenges engaging in social and community activities. A critical barrier is negative symptoms that reflect diminished feelings and thoughts that support social interaction. Several years ago, we began a process of specifying an intervention for individuals with schizophrenia and clinically meaningful negative symptoms that could be delivered in an integrated fashion with mental health services offered in VA medical centers with the primary focus of improving social and community engagement. In the present study, we examined the impact of a multi-component intervention to improve social and community participation in a group of Veterans living with schizophrenia and negative symptoms. We compared an intervention called Engaging in Community Roles and Experiences (EnCoRE) - a 12-week program of individual and group meetings that support learning and implementing skills with the goal of helping participants increase engagement in personally-relevant social and community activities - to an active wellness education control condition. Participants in both conditions attended on average of at least half of the groups that were offered, indicating that many individuals living with negative symptoms are willing to participate in an intervention to improve social and community participation. Although there were no significant differences on the two primary outcomes, those in EnCoRE showed better social and general functioning at post treatment and improved social motivational negative symptoms and decreases in perceived limitations at a 3-month follow-up. EnCoRE may be especially beneficial for participants who endorsed more dysfunctional attitudes about their abilities.

Examining the associations between PTSD symptom clusters and alcohol-related problems in a sample of low-SES treatment-seeking Black/African American adults.

Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) often co-occur. This comorbidity negatively influences treatment outcomes, functioning, and quality of life. To better understand the relation between PTSD and AUD, research has begun to examine the influence of PTSD symptom clusters on alcohol-related problems. The current study is the first to analyze the associations between PTSD symptom clusters and alcohol consumption and AUD symptom severity in a treatment-seeking sample of Black/African American (AA) adults with co-occurring AUD and PTSD symptoms. Examination of these associations may help to facilitate greater recovery in this underserved population by identifying more precise targets for treatment. PTSD symptom clusters were identified from both the current 4-factor model identified in the DSM-5 and from a recently proposed 7-factor model. Participants were Black/AA adults (50.6% male) who endorsed trauma exposure and were seeking treatment for alcohol misuse. The majority (66%) were unemployed and almost half (45%) reported an income at or lower than $20,000. In the 4-factor model, results showed Cluster D symptoms of PTSD (i.e., negative alterations in cognitions and mood) were independently associated with alcohol consequences. Use of the 7-factor model, which divides Cluster D into symptoms of negative affect and anhedonia, further demonstrated that only anhedonic symptoms were independently associated with alcohol consequences. No symptom clusters were uniquely associated with alcohol consumption. Results suggest the absence of positive emotions, rather than the presence of negative emotions, are primarily associated with alcohol-related problems in a sample of trauma-exposed, Black/AA adults seeking treatment for alcohol misuse.

SIGH, what's in a name? An examination of the factor structure and criterion validity of the (Structured Interview Guide for the) Hamilton Anxiety scale (SIGH-A) in a sample of African American adults with co-occurring trauma experience and heavy alcohol use.

The Hamilton Anxiety Inventory (HAM-A) is one of the oldest and most commonly used anxiety rating scales in clinical research. Despite its ubiquity, no studies have examined the scale's underlying factor structure and criterion validity among Black and African American adults with psychopathology (Mage = 42.25, SD = 11.44). Therefore, we estimated a confirmatory factor analysis of the commercially available Structured Interview Guide for the Hamilton Anxiety scale (SIGH-A; Williams, 1996) among African American adults (n = 88; 43% female) with co-occurring heavy alcohol use and trauma-related symptoms. Next, we examined the criterion validity of its Psychic and Somatic factors and overall anxiety severity score from participants who completed a single screening session (i.e., cross-sectional analysis) for a larger study. Results indicated that a two-factor solution provided an adequate fit to the data. Regression analyses indicated that the total SIGH-A score, but not its subscales, significantly predicted posttraumatic stress disorder (PTSD) severity. Neither the SIGH-A subscales nor total scores were significant predictors of alcohol consumption. The current findings suggest that the SIGH-A factor structure among African American adults with alcohol and trauma-related conditions is similar to previous reports that have tested largely White samples but highlight potential shortcomings when its subscales are used independently.

Cigarette Smoking Behaviors and Beliefs in Persons Living With HIV in Nairobi, Kenya.

INTRODUCTION: Persons living with HIV (PLWH) use tobacco at higher rates than the general population in both high-income countries and low- and middle-income countries. Tobacco use rates are increasing in sub-Saharan Africa, the home to most of the world's PLWH. As the reach of antiretroviral therapy (ART) expands and HIV-related morbidity and mortality wanes, tobacco use is emerging as a leading cause of disease and death in PLWH. A better understanding of tobacco use behaviors in various settings will be crucial to designing optimal tobacco control strategies. METHODS: In late 2019, we enrolled 50 PLWH cigarette smokers from 6 clinical sites in Nairobi, Kenya (4 HIV care clinics and 2 methadone maintenance programs) for one-on-one interviews focusing on their behaviors and beliefs related to tobacco use. RESULTS: Fifty PLWH smokers completed the interviews. The mean age was 38.5 ± 9.7 years (range 20-57 years) and 68% were male. All were currently receiving ART. They smoked a mean of 14.9 ± 12.4 cigarettes per day, and 82% reported smoking every day. Only 6% reported dual use of smokeless tobacco products. Nicotine dependence was moderate or high in 74%. More than a third (36%) reported a prior history of tuberculosis. In our sample, use of other substances was common, especially alcohol, marijuana, and methadone. On the motivation to quit scale, 90% were at least in the contemplation stage, but only 2% had ever received behavioral cessation counseling, and only 8% had ever used pharmacotherapy (exclusively nicotine replacement therapy). Participants reported significant concern about developing smoking-related illness, exposing others to secondary smoke, and the financial burden associated with their tobacco use. Measures of intrinsic and extrinsic motivation to quit, smoker and abstainer self-concept, and social support yielded encouraging results regarding the possibility of successful quitting. CONCLUSIONS: Tobacco use is an important health concern in PLWH in Kenya. A more thorough understanding of their tobacco use behaviors and beliefs will provide critical information for providers, public health officials, and policy makers as they redouble their efforts to confront this urgent health challenge.

A Narrative Literature Review of the Epidemiology, Etiology, and Treatment of Co-Occurring Panic Disorder and Opioid Use Disorder.

OBJECTIVE: Panic disorder is a debilitating psychiatric disorder that often co-occurs with substance use disorders. Given the current opioid epidemic, the high reported rates of comorbid panic disorder and opioid use disorder are particularly concerning. In this narrative review, we describe the literature on panic disorder and opioid use disorder co-occurrence. METHODS: 86 studies, 26 reviews, 2 commentaries, and 5 guidelines pertaining to opioid use disorder, panic disorder, and their comorbidity were identified using all EBSCO databases, PubMed, and Google Scholar. RESULTS: First, we review epidemiological literature on the prevalence of the comorbid condition above and beyond each disorder on its own. Additionally, we discuss the challenges that complicate the differential diagnosis of panic disorder and opioid use disorder and contribute to difficulties establishing rates of comorbidity. Second, we review three theoretical models that have been proposed to explain high rates of co-occurring panic disorder and opioid use disorder: the precipitation hypothesis, the self-medication hypothesis, and the shared vulnerability hypothesis. Third, we outline how co-occurring panic and opioid use disorder may impact treatment for each condition. CONCLUSION: Based on findings in the field, we provide recommendations for future research as well as treatment considerations for co-occurring panic and opioid use disorders.

Assessing the psychometric properties of the PROMIS sleep measures in persons with psychosis.

An accumulation of research has indicated that persons with psychotic disorders experience a variety of sleep disturbances. However, few studies have examined the psychometric properties of sleep assessments that are utilized in this population. We conducted two studies to examine the reliability and validity of the PROMISTM Sleep Disturbance and Sleep-Related Impairment scales in outpatient samples of persons with psychosis. In Study 1, we examined the internal consistency and convergent validity of the PROMIS sleep scales in individuals with various psychotic disorders (N = 98) and healthy controls (N = 22). The PROMIS sleep scales showed acceptable internal consistency and convergent validity in both healthy controls and individuals with psychotic disorders. In addition, replicating prior research, the PROMIS scales identified greater sleep disturbance and sleep-related impairment in participants with psychotic disorders compared to healthy controls. In Study 2, we examined the test-retest reliability (M = 358 days) of the PROMIS sleep scales in a subset (N = 37) of persons with psychotic disorders who previously participated in Study 1. We also assessed the relation between these self-report measures and actigraph sleep parameters. The results showed that PROMIS sleep measures demonstrated modest temporal stability in the current sample. Contrary to our hypothesis, there was a lack of correspondence between these scales and actigraph sleep parameters. Overall, these findings indicate that the PROMIS sleep scales are psychometrically sound measures for populations with psychosis and highlight the importance of utilizing a multi-method approach to assess sleep.

Outcomes for patients receiving telemedicine-delivered medication-based treatment for Opioid Use Disorder: A retrospective chart review.

This report builds on a previous study that describes the collaboration between an urban academic medical center and a rural drug treatment center, the goal of which is to provide medication-based treatment to individuals with OUD via videoconferencing. We describe results of a retrospective chart review of 472 patients treated in the program between August 2015 and April 2019. We examined several demographic and substance use variables for individuals who consented to telemedicine treatment, retention in treatment over time, and opioid use over time to understand further the impact of prescribing buprenorphine and naltrexone via telemedicine to patients in a rural OUD treatment setting. Our findings support the effectiveness of prescribing medications via telemedicine. The inclusion of more than three times as many patients as in our prior report revealed retention rates and toxicology results that are comparable to face-to-face treatment. These findings have implications for policymakers and clinicians considering implementation of similar programs.

Relationships between chronic pain and mood symptoms among veterans with bipolar disorder.

BACKGROUND: Chronic pain is highly prevalent among individuals with mood disorders. While much is known about the relationship between pain and unipolar depression, little is known about pain experiences among people with bipolar disorder. This pilot study addresses this gap by examining pain and its relationship to mood and functioning in a sample of US military veterans with bipolar disorder. METHODS: Qualitative interviews were conducted with 15 veterans with bipolar disorder and chronic pain who were recruited from outpatient services within a Veterans Affairs medical center. RESULTS: Veterans reported a bidirectional relationship between pain and bipolar depression. When discussing manic episodes, individuals' experiences varied between notable reductions in pain (usually in euphoric states), increases in pain (usually in angry/irritable states), and feeling disconnected from pain. Many reported that increased activity when manic contributed to worse pain after an episode. Veterans clearly articulated how these connections negatively affected their functioning and quality of life. LIMITATIONS: This was a small, retrospective study that included a non-random sample of veteran participants from one VA medical center. All veterans were engaged in outpatient mental health care, so the majority reported that their mood has been well-stabilized through medications and/or psychotherapy. CONCLUSIONS: Chronic pain experiences appear to be related to depressive and manic mood states and significantly affects functioning and quality of life in Veterans with bipolar disorder. This study highlights the need to assess chronic pain among veterans with bipolar disorder, as changes in mood could have significant implications for functioning and pain management.

Sleep Problems and Social Impairment in Psychosis: A Transdiagnostic Study Examining Multiple Social Domains.

Psychotic disorders are characterized by profound social impairment. An accumulation of research has explored the contribution of symptoms, cognitive functioning, and behavioral skills deficits to this social dysfunction. Recent research indicates that sleep disturbance has significant social implications in nonclinical populations-this research suggests that sleep problems may also be relevant to understanding social impairment in psychosis. This study adopted a symptom-oriented dimensional approach to examine how sleep disturbance and sleep-related impairment are related to multiple social domains within a transdiagnostic sample (N = 90). This sample included individuals with a variety of psychotic disorders (n = 75) along with healthy non-clinical participants (n = 15) to ensure sampling across the full range of sleep problems and social functioning. Social domains spanned self-reported perceptions of social relationships, social functioning in the community, and behavioral assessments of social competence. We hypothesized that greater sleep disturbance and sleep-related impairment would be associated with more negative or problematic perceptions of social relationships (i.e., less social support, less companionship, and greater distress), poorer social functioning in the community, smaller social networks, and poorer behavioral ratings of social competency. Results supported these hypotheses indicating that sleep disturbance and sleep-related impairment have widespread deleterious impacts on perceptions of social relationships, social functioning, and competence. Sleep disturbance retained associations with perceptions of social relationships, social functioning, and social competence even after controlling for total symptoms or cognitive functioning. These findings indicate that sleep problems may have important implications for fully understanding the causes of social impairment in psychosis.
