Experimental Psychopathology and Treatment - Abstract
Item does not contain fulltext Background: The application of weekly doses of D-cycloserine (DCS) to the enhancement of exposure-based treatments has been a particular achievement of translational research. It is not known, however, whether this enhancement effect can be extended to other forms of learning. In this study, we investigated the relative benefit of DCS versus placebo for enhancing nonemotional verbal and nonverbal memory across weekly trials. Methods: We randomized healthy participants to weekly doses of 50 mg DCS or placebo, with 33 participants completing a 5-week protocol. Participants completed baseline neuropsychological evaluation and then 4 subsequent weeks of repeated learning tasks. Results: No improvement was found in immediate or delayed memory following single doses of DCS for the memory tasks repeated on a weekly basis. Trends for an advantage of DCS were evident for novel word lists given each week. Conclusions: The learning tasks in our study were particularly distinct from the extinction learning paradigms that have shown strong DCS effects, and we were unable to demonstrate useful DCS effects with these nonemotional stimuli. Additional research is needed to elucidate the bounds of DCS augmentation effects on therapeutic learning.

- Abstract
In this reply to K. E. Freedland's (see record 2004-13299-002) comments on R. J. Contrada et al. (see record 2004-13299-001), it is shown that the statistical issues he raised, and his preferred interpretation of the findings, were adequately addressed in the original article. It is argued that methodological limitations also were fully characterized and do not differ in kind from those of biomedical studies. Other issues discussed include the merits of focusing on distal versus proximal causation, plausibility of explanatory mechanisms for health effects of religious involvement, and potential practical applications that do not require manipulation of religious involvement. The article is concluded by commenting on subtle aspects of discourse that may unnecessarily polarize discussions of possible physical health effects of religious involvement. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: The impact of obtaining second-opinion consultations on diagnoses of schizophrenia spectrum disorders was evaluated., Methods: A retrospective chart review was conducted for 177 patients referred to a psychosis consultation service at an academic medical center from January 1, 2017, to October 1, 2023; these consultations aimed to clarify a diagnosis of psychosis. Diagnoses made before and after consultations were compared, and treatment recommendations resulting from the consultation visit were summarized., Results: Among patients without a preconsultation diagnosis of schizophrenia, 28% (N=28 of 100) received a postconsultation diagnosis of schizophrenia. Among 62 patients with a postconsultation diagnosis of treatment-resistant schizophrenia (TRS), 56% (N=35) received this diagnosis only after consultation. Nearly all of these patients were advised to begin taking clozapine, and electroconvulsive therapy was less commonly recommended., Conclusions: Expert consultation facilitates timely identification and optimal treatment of schizophrenia and its more severe subtype, TRS., Competing Interests: Dr. Lim reports receiving research grants from Karuna, Merck, and Neurocrine Biosciences; consultant honoraria from Karuna; and medical honoraria from MDedge and Hatherleigh.

- Abstract
Attempts to meaningfully engage people with serious mental illnesses (SMI) as allies in conducting research have often failed because researchers tend to decide on the research topic without including community members. Academic researchers can avoid this pitfall by collaborating with community members to conduct a needs assessment to identify relevant research topics and build trust. Here, we report on the results of a psychosocial needs assessment for adult mental health service users in Massachusetts conducted by an academic-peer research team. The project was initiated as part of an academic mental health center's efforts to conduct community-based participatory research (CBPR) with a group of people with SMI. People with SMI were hired and trained to co-lead research projects and the development of the listening group guide, and they conducted 18 listening groups with 159 adults with mental health conditions. The data were transcribed, and rapid analysis employing qualitative and matrix classification methods was used to identify service need themes. Six themes emerged from qualitative analysis: reduce community and provider stigma, improve access to services, focus on the whole person, include peers in recovery care, have respectful and understanding clinicians, and recruit diverse staff. The policy and practice implications of these findings include creating a stronger culture of innovation within provider organizations, developing specific plans for improving recruitment and retention of peer workers and a multicultural workforce, enhancing training and supervision in cultural humility, communicating respectfully with clients, and including peers in quality improvement activities.

- Abstract
Objective: Adults with serious mental illness have high rates of tobacco use disorder and underuse pharmacotherapy for tobacco cessation. In a previous randomized controlled trial, participants receiving community health worker (CHW) support and education for their primary care providers (PCPs) had higher tobacco abstinence rates at 2 years, partly because of increased initiation of tobacco-cessation pharmacotherapy. The authors aimed to determine the association between CHW-participant engagement and tobacco abstinence outcomes., Methods: The authors conducted a secondary, mixed-methods analysis of 196 participants in the trial's intervention arm. Effects of the number and duration of CHW visits, number of smoking-cessation group sessions attended, and number of CHW-attended PCP visits on initiation of tobacco-cessation pharmacotherapy and tobacco abstinence were modeled via logistic regression. Interviews with 12 CHWs, 17 patient participants, and 17 PCPs were analyzed thematically., Results: Year 2 tobacco abstinence was significantly associated with CHW visit number (OR=1.85, 95% CI=1.29-2.66), visit duration (OR=1.51, 95% CI=1.00-2.28), and number of group sessions attended (OR=1.85, 95% CI=1.33-2.58); effects on pharmacotherapy initiation were similar. One to three CHW visits per month across 2 years were optimal for achieving abstinence. Interviews identified CHW-patient engagement facilitators (i.e., trust, goal accountability, skills reinforcement, assistance in overcoming barriers to treatment access, and adherence). Training and supervision facilitated CHW effectiveness; barriers included PCPs' and care teams' limited understanding of the CHW role., Conclusions: Greater CHW-participant engagement, within feasible dose ranges, was associated with tobacco abstinence among adults with serious mental illness. Implementation of CHW interventions may benefit from further CHW training and integration within clinical teams., Competing Interests: Drs. Cather and Evins report serving as consultants for Charles River Analytics. The other authors report no financial relationships with commercial interests.

- Abstract
Background: The absence of systematic screening for psychosis within general psychiatric services contribute to substantial treatment delays and poor long-term outcomes. We conducted a meta-analysis to estimate rates of psychotic experiences, clinical high-risk for psychosis syndrome (CHR-P), and psychotic disorders identified by screening treatment-seeking individuals to inform implementation recommendations for routine psychosis screening in general psychiatric settings., Methods: PubMed and Web of Science databases were searched to identify empirical studies that contained information on the point prevalence of psychotic experiences, CHR-P, or psychotic disorders identified by screening inpatient and outpatient samples aged 12-64 receiving general psychiatric care. Psychotic experiences were identified by meeting threshold scores on validated self-reported questionnaires, and psychotic disorders and CHR-P by gold-standard structured interview assessments. A meta-analysis of each outcome was conducted using the Restricted Maximum Likelihood Estimator method of estimating effect sizes in a random effects model., Results: 41 independent samples (k=36 outpatient) involving n=25,751 patients (58% female, mean age: 24.1 years) were included. Among a general psychiatric population, prevalence of psychotic experiences was 44.3% (95% CI: 35.8-52.8%; 28 samples, n=21,957); CHR-P was 26.4% (95% CI: 20.0-32.7%; 28 samples, n=14,395); and psychotic disorders was 6.6% (95% CI: 3.3-9.8%; 32 samples, n=20,371)., Conclusions: High rates of psychotic spectrum illness in general psychiatric settings underscore need for secondary prevention with psychosis screening. These base rates can be used to plan training and resources required to conduct assessments for early detection, as well as build capacity in interventions for CHR-P and early psychosis in non-specialty mental health settings., Competing Interests: Conflicts of Interest and Sources of Funding: The authors report no conflicts of interest.

- Abstract
Background: Smoking is a major contributor to morbidity and mortality among individuals with serious mental illness (SMI) and social networks may play an important role in smoking behaviors., Aims: Our objectives were to (1) describe the network characteristics of adults with SMI who smoke tobacco (2) explore whether network attributes were associated with nicotine dependence., Methods: We performed a secondary analysis of baseline data from a tobacco smoking cessation intervention trial among 192 participants with SMI. A subgroup ( n = 75) completed questions on the characteristics of their social network members. The network characteristics included network composition (e.g. proportion who smoke) and network structure (e.g. density of connections between members). We used multilevel models to examine associations with nicotine dependence., Results: Participant characteristics included: a mean age 50 years, 49% women, 48% Black, and 41% primary diagnosis of schizophrenia/schizoaffective disorder. The median personal network proportion of active smokers was 22%, active quitters 0%, and non-smokers 53%. The density of ties between actively smoking network members was greater than between non-smoking members (55% vs 43%, p = .02). Proportion of network smokers was not associated with nicotine dependence., Conclusions: We identified potential social network challenges and assets to smoking cessation and implications for network interventions among individuals with SMI.

- Abstract
Background: Hallucinations have been linked to failures in metacognitive reflection suggesting an association between hallucinations and overestimation of performance, although the cross-sectional findings are inconsistent. This inconsistency may relate to the fluctuating hallucinatory experiences that are not captured in cross-sectional studies. Ecological Momentary Assessment (EMA) captures in-the-moment experiences over time so can identify causal relationships between variables such as the associations between metacognition and hallucinatory experience in daily life and overcome problems in cross-sectional designs., Methods: Participants (N = 41) experiencing daily hallucinations completed baseline questionnaires and smartphone surveys 7 times per day for 14 days. They were prompted to identify a task they would complete in the next 4 h and to make metacognitive predictions around the likelihood of completing the task, the difficulty of the task, and how well they would complete it (standard of completion)., Results: 76 % finished the 14-days of assessment with an average of 42.2 % survey completion. Less accurate metacognition was associated with more hallucinations, but less accurate likelihood and standard of completion was associated with fewer hallucinations. Using a cross-lagged analysis, metacognitive predictions around the likelihood of completion (p < .001) and standard of completion (p = .01) predicted hallucination intensity at the following timepoint, and metacognitive predictions regarding likelihood of completion (p = .02) predicted hallucination control at the following timepoint., Discussion: Interventions that aim to improve metacognitive ability in-the-moment may serve to reduce the intensity and increase the control of hallucinations., Competing Interests: Declaration of competing interest No conflicts to report., (Copyright © 2023 Elsevier B.V.

- Abstract
Objective: Use of combustible alternative tobacco products (ATPs; e.g., little cigars, loose tobacco, multiple tobacco product types [TPTs]) is increasingly common. Inexpensive, combusted ATPs (e.g little cigars) are predominantly marketed to lower-income communities. Prevalence of combusted ATP use among those with serious mental illness (SMI) is unknown., Methods: We examined rates and correlates of combusted ATP use and association with tobacco abstinence in a secondary analysis of a single-cohort (N = 1007) trial of tobacco-smoking adults with SMI and severe SMI-related functional impairment. The parent study aimed to test a community-health worker-delivered intervention for promoting smoking cessation among adults with SMI. Participants were surveyed at baseline on demographic and smoking characteristics including combusted TPT (cigarettes, cigars/little cigars, loose tobacco), and breath carbon-monoxide (CO). CO-verified 7-day point-prevalence tobacco abstinence was assessed at Year 2., Results: At baseline, 59% of participants reported using cigarettes only, 25% multiple (>1) combusted TPTs, 12% cigars/little cigars only, and 4% loose tobacco (e.g., "rollies", pipes) only. Those reporting any ATP use at baseline had higher expired CO concentration and reported using more tobacco products per day than exclusive cigarette users (p's < 0.05). ATP use was not associated with abstinence in adjusted logistic regression models (p's > 0.05)., Conclusions: Use of ATPs was associated with use of more tobacco products per day and greater tobacco toxicant exposure than exclusive cigarette use in this population. Future policy efforts work to change preferential taxation policies (e.g., lower taxation for cigar products) and disproportionate marketing of ATPs to lower-income communities., Competing Interests: Declaration of Competing Interest This work was funded by the Patient Centered Outcomes Research Institute (PCORI) Large Pragmatic Trial #1504-30472 (“Integrated Smoking Cessation Treatment for Smokers with Serious Mental Illnesses”; PI: Evins).

- Abstract
Discoid lupus erythematosus (DLE) is the most common form of cutaneous lupus
1 . It can cause permanent scarring. The pathophysiology of is not fully understood. Plasmacytoid dendritic cells are found in close association with apoptotic keratinocytes inferring close cellular signalling. Matrix Associated Laser Desorption Ionisation (MALDI) combined with Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR-MS) is an exquisitely sensitive combination to examine disease processes at the cellular and molecular level. Active areas of discoid lupus erythematosus were compared with normal perilesional skin using MALDI combined with FT-ICR-MS. A unique set of biomarkers, including epidermal lipids is identified in active discoid lupus. These were assigned as sphingomyelins, phospholipids and ceramides. Additionally, increased levels of proteins from the keratin, and small proline rich family, and aromatic amino acids (tryptophan, phenylalanine, and tyrosine) in the epidermis are observed. These techniques, applied to punch biopsies of the skin, have shown a distinctive lipid profile of active discoid lupus. This profile may indicate specific lipid signalling pathways. Lipid rich microdomains (known as lipid rafts) are involved in cell signalling and lipid abnormalities have been described with systemic lupus erythematosus which correlate with disease activity., (© 2023.

- Abstract
Importance: Tobacco smoking drives markedly elevated cardiovascular disease risk and preventable death in persons with serious mental illness, and these risks are compounded by the high prevalence of overweight/obesity that smoking cessation can exacerbate. Guideline-concordant combined pharmacotherapy and behavioral smoking cessation treatment improves abstinence but is not routinely offered in community settings, particularly to those not seeking to quit smoking immediately., Objective: To determine the effectiveness of an 18-month pharmacotherapy and behavioral smoking cessation intervention incorporating weight management and support for physical activity in adults with serious mental illness interested in quitting smoking within 1 or 6 months., Design, Setting, and Participants: This was a randomized clinical trial conducted from July 25, 2016, to March 20, 2020, at 4 community health programs. Adults with serious mental illness who smoked tobacco daily were included in the study. Participants were randomly assigned to intervention or control, stratified by willingness to try to quit immediately (within 1 month) or within 6 months. Assessors were masked to group assignment., Interventions: Pharmacotherapy, primarily varenicline, dual-form nicotine replacement, or their combination; tailored individual and group counseling for motivational enhancement; smoking cessation and relapse prevention; weight management counseling; and support for physical activity. Controls received quitline referrals., Main Outcome and Measures: The primary outcome was biochemically validated, 7-day point-prevalence tobacco abstinence at 18 months., Results: Of the 298 individuals screened for study inclusion, 192 enrolled (mean [SD] age, 49.6 [11.7] years; 97 women [50.5%]) and were randomly assigned to intervention (97 [50.5%]) or control (95 [49.5%]) groups. Participants self-identified with the following race and ethnicity categories: 93 Black or African American (48.4%), 6 Hispanic or Latino (3.1%), 90 White (46.9%), and 9 other (4.7%). A total of 82 participants (42.7%) had a schizophrenia spectrum disorder, 62 (32.3%) had bipolar disorder, and 48 (25.0%) had major depressive disorder; 119 participants (62%) reported interest in quitting immediately (within 1 month). Primary outcome data were collected in 183 participants (95.3%). At 18 months, 26.4% of participants (observed count, 27 of 97 [27.8%]) in the intervention group and 5.7% of participants (observed count, 6 of 95 [6.3%]) in the control group achieved abstinence (adjusted odds ratio [OR], 5.9; 95% CI, 2.3-15.4; P < .001). Readiness to quit within 1 month did not statistically significantly modify the intervention's effect on abstinence. The intervention group did not have significantly greater weight gain than the control group (mean weight change difference, 1.6 kg; 95% CI, -1.5 to 4.7 kg)., Conclusions and Relevance: Findings of this randomized clinical trial showed that in persons with serious mental illness who are interested in quitting smoking within 6 months, an 18-month intervention with first-line pharmacotherapy and tailored behavioral support for smoking cessation and weight management increased tobacco abstinence without significant weight gain., Trial Registration: ClinicalTrials.gov Identifier: NCT02424188.

- Abstract
Cannabis use is common in first-episode psychosis (FEP) but evidence is mixed about the extent to which cannabis use predicts symptoms and functional outcomes among those who seek treatment. This study sought to characterize cannabis use patterns and examine the relationship with clinical outcomes, including interactions with early intervention services (EIS). Data were drawn from the Recovery After an Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study including FEP individuals receiving treatment at sites randomized to provide either EIS (NAVIGATE) or community care (CC). Cannabis use was assessed monthly and symptom and functioning data were collected at baseline, 6, 12, 18, and 24 months. Among the 404 participants enrolled, 334 were classified into four cannabis use groups (consistent, sporadic, stopped, and never users) based on their use during the first year. Consistent and sporadic cannabis users were younger, whereas those who had stopped using were older. Sporadic users had the highest depression and the lowest functioning at baseline and improved less during treatment in negative emotions and intrapsychic foundations (e.g., motivation and sense of purpose) than non-users. However, sporadic users who received NAVIGATE improved more in overall symptoms and functioning than those who received CC. Consistent users did not tend to differ in their trajectories from non-users. Individuals with FEP who use cannabis sporadically showed less clinical improvement than non-users. However, EIS treatment reduced the negative effects of sporadic cannabis use on clinical outcomes. Those who use cannabis sporadically may have unique needs that require attention in EIS., (© 2022.

- Abstract
Background: Environmental adversity and subclinical symptoms of psychopathology in adolescents increase their risk for developing a future psychiatric disorder, yet interventions that may prevent poor outcomes in these vulnerable adolescents are not widely available., Aims: To develop and test the feasibility and acceptability of a prevention-focused program to enhance resilience in high-risk adolescents., Method: Adolescents with subclinical psychopathology living in a predominantly low-income, Latinx immigrant community were identified during pediatrician visits. A group-based intervention focused on teaching emotion recognition and regulation skills was piloted in three cohorts of adolescents ( n = 11, 10, and 7, respectively), using a single arm design. The second and third iterations included sessions with parents., Results: Eighty-eight percent of participants completed the program, which was rated as beneficial. Also, from baseline to end of treatment, there was a significant decrease in subclinical symptoms and a significant increase in the adolescents' positive social attribution bias (all p < 0.05)., Conclusions: A resilience-focused intervention administered to high-risk adolescents was found to be feasible and acceptable to participants. Future work is needed to determine whether such a program can reduce the incidence of negative outcomes, such as the development of psychiatric disorders and related disability, in this population.

- Abstract
Background: Tobacco smoking is highly prevalent among persons with serious mental illness (SMI) and is the largest contributor to premature mortality in this population. Evidence-based smoking cessation therapy with medications and behavioral counseling is effective for persons with SMI, but few receive this treatment. Mental health providers have extensive experience working with clients with SMI and frequent treatment contacts, making them well positioned to deliver smoking cessation treatment. However, few mental health providers feel adequately trained to deliver this treatment, and many providers believe that smokers with SMI are not interested in quitting or have concerns about the safety of smoking cessation pharmacotherapy, despite substantial evidence to the contrary., Objective: We present the protocol for the pilot "IMPACT" (Implementing Action for Tobacco Smoking Cessation Treatment) study, which aims to pilot test a multicomponent implementation intervention to increase the delivery of evidence-based tobacco smoking cessation treatment in community mental health clinics., Methods: We are using a prepost observational design to examine the effects of an implementation intervention designed to improve mental health providers' delivery of the following four evidence-based practices related to smoking cessation treatment: (1) assessment of smoking status, (2) assessment of willingness to quit, (3) behavioral counseling, and (4) pharmacotherapy prescribing. To overcome key barriers related to providers' knowledge and self-efficacy of smoking cessation treatment, the study will leverage implementation strategies including (1) real-time and web-based training for mental health providers about evidence-based smoking cessation treatment and motivational interviewing, including an avatar practice module; (2) a tobacco smoking treatment protocol; (3) expert consultation; (4) coaching; and (5) organizational strategy meetings. We will use surveys and in-depth interviews to assess the implementation intervention's effects on providers' knowledge and self-efficacy, the mechanisms of change targeted by the intervention, as well as providers' perceptions of the acceptability, appropriateness, and feasibility of both the evidence-based practices and implementation strategies. We will use data on care delivery to assess providers' implementation of evidence-based smoking cessation practices., Results: The IMPACT study is being conducted at 5 clinic sites. More than 50 providers have been enrolled, exceeding our recruitment target. The study is ongoing., Conclusions: In order for persons with SMI to realize the benefits of smoking cessation treatment, it is important for clinicians to implement evidence-based practices successfully. This pilot study will result in a set of training modules, implementation tools, and resources for clinicians working in community mental health clinics to address tobacco smoking with their clients.

- Abstract
Importance: People with serious mental illness (SMI), defined as a diagnosis of schizophrenia spectrum disorder, bipolar disorder, or disabling major depressive disorder) die approximately 10 to 25 years earlier than the general population., Objective: To develop the first-ever lived experience-led research agenda to address early mortality in people with SMI., Evidence Review: A virtual 2-day roundtable comprising 40 individuals convened on May 24 and May 26, 2022, and used a virtual Delphi method to arrive at expert group consensus. Participants responded to 6 rounds of virtual Delphi discussion via email that prioritized research topics and agreement on recommendations. The roundtable was composed of individuals with lived experience of mental health and/or substance misuse, peer support specialists, recovery coaches, parents and caregivers of people with SMI, researchers and clinician-scientists with and without lived experience, policy makers, and patient-led organizations. Twenty-two of 28 (78.6%) of the authors who provided data represented people with lived experiences. Roundtable members were selected by reviewing the peer-reviewed and gray literature on early mortality and SMI, direct email, and snowball sampling., Findings: The following recommendations are presented in order of priority as identified by the roundtable participants: (1) improve the empirical understanding of the direct and indirect social and biological contributions of trauma on morbidity and early mortality; (2) advance the role of family, extended families, and informal supporters; (3) recognize the importance of co-occurring disorders and early mortality; (4) redefine clinical education to reduce stigma and support clinicians through technological advancements to improve diagnostic accuracy; (5) examine outcomes meaningful to people with an SMI diagnosis, such as loneliness and sense of belonging, and stigma and their complex relationship with early mortality; (6) advance the science of pharmaceuticals, drug discovery, and choice in medication use; (7) use precision medicine to inform treatment; and (8) redefine the terms system literacy and health literacy., Conclusions and Relevance: The recommendations of this roundtable are a starting point for changing practice and highlighting lived experience-led research priorities as an option to move the field forward.

- Abstract
Objective: Individuals with serious mental illness have a high prevalence of tobacco use disorder and related early mortality but underutilize smoking cessation medication. The authors determined whether clinician-delivered education to primary care providers regarding safety, efficacy, and importance of cessation medication (provider education [PE]) alone or combined with community health worker (CHW) support would increase tobacco abstinence in this population, compared with usual care., Methods: All adult current tobacco smokers receiving psychiatric rehabilitation for serious mental illness through two community agencies in Greater Boston were eligible, regardless of readiness to quit smoking. Primary care clinics were cluster randomized to PE or usual care, with a nested, participant-level randomization to CHW or no CHW in PE-assigned clinics. The primary outcome was blindly assessed, biochemically verified tobacco abstinence at year 2., Results: Overall, 1,010 eligible participants were enrolled. PE was delivered to providers in 53 of 55 assigned clinics; 220 of 336 CHW-assigned participants consented to CHW support. Year 2 abstinence rates were significantly higher among participants assigned to PE+CHW versus usual care (12% vs. 5%; adjusted odds ratio [AOR]=2.40, 95% confidence interval [CI]=1.20-4.79) or PE alone (12% vs. 7%; AOR=1.84, 95% CI=1.04-3.24). No effect of PE alone on abstinence was detected. Compared with participants assigned to usual care, those assigned to PE+CHW had greater odds of varenicline use (OR=2.77, 95% CI=1.61-4.75), which was associated with higher year 2 abstinence (OR=1.97, 95% CI=1.16-3.33)., Conclusions: Combined PE and CHW tobacco cessation support increased tobacco abstinence rates among adults with serious mental illness.

- Abstract
Background: Approximately one-fifth of high-school seniors and college students currently vape nicotine. Adolescents express a desire to quit vaping, and case reports have shown promise for e-cigarette tapering with dual behavioral and pharmacologic therapies. However, there are no published clinical trials to date that test these intervention approaches for adolescent nicotine vaping cessation. In this three-arm randomized, placebo-controlled, parallel-group study, we aim to assess the efficacy of varenicline in combination with brief behavioral counseling and texting support on vaping cessation in adolescents dependent on vaped nicotine., Methods: The study will enroll 300 individuals between the ages of 16-25 with daily or near-daily nicotine vaping who reside in the Greater Boston area. Participants will be randomly assigned in a 1:1:1 ratio in blocks of six to one of the three arms: (1) a 12-week course of varenicline titrated to 1 mg bid, brief behavioral counseling delivered by a lay counselor, and an introduction to This is Quitting (TIQ) texting support created by the Truth Initiative; (2) a 12-week course of placebo, brief behavioral counseling, and TIQ; and (3) 12 weeks of enhanced usual care, consisting of advice to quit and an introduction to TIQ. The primary outcome will be biochemically verified continuous vaping abstinence at the end of the treatment (week 12). Secondary outcomes include continuous abstinence at follow-up (week 24), 7-day point prevalence abstinence at weeks 12 and 24, safety and tolerability of varenicline in an adolescent vaping population, as well as change in mood and nicotine withdrawal symptoms across the intervention period. Exploratory outcomes include change in comorbid substance use behaviors and nicotine dependence. Analysis will be intent-to-treat, with multiple imputation sensitivity analyses for participants with missing or incomplete outcome data., Discussion: This is the first study to evaluate varenicline in combination with a novel, brief, lay counselor delivered vaping cessation program for adolescents who vape nicotine. Results will inform clinicians on the effectiveness and acceptability of this promising, but not yet tested intervention.

- Abstract
Objectives: Disengagement from treatment is common in first episode schizophrenia (FES) and is associated with poor outcomes. Our aim was to determine whether hippocampal subfield volumes predict disengagement during maintenance treatment of FES., Methods: FES patients were recruited from sites in Boston, New York, Shanghai, and Changsha. After stabilization on antipsychotic medication, participants were randomized to add-on citalopram or placebo and followed for 12 months. Demographic, clinical and cognitive factors at baseline were compared between completers and disengagers in addition to volumes of hippocampal subfields., Results: Baseline data were available for 95 randomized participants. Disengagers (n = 38, 40%) differed from completers (n = 57, 60%) by race (more likely Black; less likely Asian) and in more alcohol use, parkinsonism, negative symptoms and more impairment in visual learning and working memory. Bilateral dentate gyrus (DG), CA1, CA2/3 and whole hippocampal volumes were significantly smaller in disengagers compared to completers. When all the eight volumes were entered into the model simultaneously, only left DG volume significantly predicted disengagement status and remained significant after adjusting for age, sex, race, intracranial volume, antipsychotic dose, duration of untreated psychosis, citalopram status, alcohol status, and smoking status (P < .01). Left DG volume predicted disengagement with 57% sensitivity and 83% specificity., Conclusions: Smaller left DG was significantly associated with disengagement status over 12 months of maintenance treatment in patients with FES participating in a randomized clinical trial. If replicated, these findings may provide a biomarker to identify patients at risk for disengagement and a potential target for interventions., (© The Author(s) 2022.

- Abstract
Purpose: In the US, Black people diagnosed with schizophrenia experience worse psychosocial and clinical outcomes than their White counterparts. While racism-related factors contribute to these disparities, an additional understudied explanation may be that psychosocial treatments for psychotic disorders are less effective for Black than White individuals. The purpose of this study is to examine the extent to which best treatment practices for first-episode psychosis (FEP) are effective for Black and White participants., Methods: We conducted a secondary data analysis of the Recovery After an Initial Schizophrenia Episode Early Treatment Program (RAISE-ETP), a two-year multisite trial that compared a coordinated specialty care intervention for FEP (NAVIGATE) to community care as usual (CC) in 34 sites across the US. Specifically, we compared interviewer-rated quality of life and symptoms, as well as self-reported mental health and stigma, between 139 Non-Latinx Black and 172 Non-Latinx White participants with FEP in NAVIGATE and CC., Results: We found few differences between Black and White participants over two-year outcomes, either overall or in terms of benefit from NAVIGATE. Across both treatment conditions, Black participants improved less than White participants on positive symptoms, an effect driven primarily by suspiciousness/persecution. In NAVIGATE, self-reported mental health stigma decreased for both Black and White participants, while in CC stigma decreased for White participants but increased for Black participants. This effect was driven primarily by experienced stigma rather than self-stigma., Conclusion: NAVIGATE benefits both Black and White individuals diagnosed with FEP. Mental health stigma and positive symptoms may be particularly important aspects of treatment for Black individuals diagnosed with FEP., (© 2022.

- Abstract
Background: The U.S. Food and Drug Administration and the government of New Zealand have proposed a reduction of the nicotine content in cigarettes to very low levels. This study examined the potential effects of this regulation in smokers with affective disorders., Methods: In a randomized controlled parallel group trial conducted at two sites in the USA (Penn State University, Hershey, PA and Massachusetts General Hospital, Boston, MA) 188 adult smokers with a current (n = 118) or lifetime (n = 70) anxiety or unipolar mood disorder, not planning to quit in the next 6 months, were randomly assigned (1:1) to smoke either Usual Nicotine Content (UNC) (11.6 mg nicotine/cigarette) research cigarettes, or Reduced Nicotine Content (RNC) research cigarettes where the nicotine content per cigarette was progressively reduced to 0.2 mg in five steps over 18 weeks. Participants were then offered the choice to either receive assistance to quit smoking, receive free research cigarettes, or resume using their own cigarette brand during a 12-week follow-up period. Main outcomes were biomarkers of nicotine and toxicant exposure, smoking behavior and dependence and severity of psychiatric symptoms. The pre-registered primary outcome was plasma cotinine., Results: A total of 143 (76.1%) randomized participants completed the randomized phase of the trial, 69 (73.4%) in the RNC group and 74 (78.8%) in the UNC group. After switching to the lowest nicotine content cigarettes, compared to smokers in the UNC group, at the last randomized visit the RNC group had significantly lower plasma cotinine (metabolite of nicotine): difference between groups, -175.7, 95% CI [-218.3, -133.1] ng/ml. Urine NNAL (metabolite of NNK, a lung carcinogen), exhaled carbon-monoxide, cigarette consumption, and cigarette dependence were also significantly lower in the RNC group than the UNC group. No between-group differences were found on a range of other biomarkers (e.g. 8-isoprostanes) or health indicators (e.g. blood pressure), or on 5 different psychiatric questionnaires, including the Kessler K6 measure of psychological distress. At the end of the subsequent 12-week treatment choice phase, those randomized to the RNC group were more likely to have quit smoking, based on initial intent-to-treat sample, n = 188 (18.1% RNC v 4.3% UNC, p = 0.004)., Conclusion: Reducing nicotine content in cigarettes to very low levels reduces some toxicant exposures and cigarette addiction and increases smoking cessation in smokers with mood and/or anxiety disorders, without worsening mental health., Trial Registration: TRN: NCT01928758, registered August 21, 2013., Competing Interests: JF has done paid consulting for pharmaceutical companies involved in producing smoking cessation medications, including GSK, Pfizer, Novartis, J&J, and Cypress Bioscience, and received a research grant from Pfizer Inc (not related to reduced nicotine cigarettes).

- Abstract
Objective: This pilot project aimed to maximize COVID-19 vaccine uptake among patients with serious mental illness. Psychiatric providers were engaged to directly address COVID-19 vaccine-related concerns with patients during outpatient visits., Methods: A quality improvement project encouraged COVID-19 vaccinations in a cohort of outpatients treated with clozapine (N=193, ages 19-81 years, mean age=46.4 years) at a community mental health center. In-service education was provided to clinicians to identify vaccine-hesitant patients and build vaccine confidence. A vaccination-monitoring tool was created and embedded in patients' electronic medical records. Starting in February 2021, the tool guided semistructured interviews at each visit and supported population-based management., Results: The full COVID-19 vaccination rate by June 30, 2021, was 84% among the outpatients, compared with the estimated state rate on the same date of between 62.1% and 77.3%., Conclusions: The active involvement of psychiatric providers in preventive health care can help increase vaccination rates among patients with serious mental illness.

- Abstract
Objective: Individuals with mental health challenges are at particularly high risk of experiencing negative outcomes (e.g., worsening of mental health, increased risk of mortality) due to the coronavirus disease (COVID-19) pandemic. Peer specialists may have the benefit of several protective factors, including higher levels of social support and better illness self-management skills that buffer against negative effects of the pandemic. In this study, we compared the differences in the impact of COVID-19 on those trained as peer specialists (e.g., certified peer specialists, recovery coaches) to those not trained in this role., Method: Participants with self-reported mental health and/or substance use challenges completed an online survey to collect information on their experiences during COVID-19 (Epidemic-Pandemic Impacts Inventory [EPII]), loneliness (3-item Loneliness Scale), and access to and satisfaction with mental health support. Respondents self-identified as peer specialists or not., Results: One hundred seventy-three U.S. resident participants from 23 states were included in the final analysis: 109 were peer specialists and 64 were nonpeer specialists. Those who were trained as peer specialists reported fewer negative outcomes during the pandemic, including less disruption in employment, less loneliness, and less worsening of mental health, while reporting more positive attitudes in the face of difficulties. Peer specialists were also likely to report more access to and satisfaction with mental health services., Conclusions and Implications for Practice: Possibly as a function of their role, peer specialists reported better mental health outcomes during COVID-19, providing key, empirical evidence to support the benefits of helping others.

- Abstract
Background: Self-defining memories (SDMs) are important for identifying one's purpose in life, achieving goals, and overcoming challenging situations. Individual studies have demonstrated differences in the characteristics of SDMs between clinical and non-clinical populations. This systematic literature review aimed to summarise and compare SDM characteristics among those with mental, substance use, cognitive, neurodevelopmental, and physical health challenges., Methods: Peer-reviewed English-language studies were included if they evaluated SDMs in these groups., Results: Thirty-five studies (N = 3123) were included. SDM content across all clinical populations tended to focus on illness themes. SDMs were generally less specific and integrated in those with mental health or substance use disorders as compared to non-clinical populations. SDM specificity and integration findings were more mixed in those with cognitive, neurodevelopmental, and physical health challenges., Conclusions: Specific differences emerged between groups of individuals which may be related to illness characteristics, recovery trajectory, and individual differences in the ability to understand and process difficult life events.

- Abstract
Background: Subclinical psychotic symptoms are common in the general population and are often benign. However, those that become distressing or persistent may increase risk for the development of a psychotic disorder. Cognitive models have proposed that certain appraisals of hallucinatory experiences can lead to delusional beliefs, particularly if an individual is experiencing negative mood. However, the dynamic relationships among these symptoms are poorly understood. This study examined the longitudinal relationships among subclincal hallucinations, delusional ideation, and depression in a sample of young adults., Methods: 677 college students completed baseline questionnaires to assess: delusional ideation (Peters Delusions Inventory), hallucinations (Launay-Slade Hallucinations Scale-Extended), and depression (Beck Depression Inventory). These measures were repeated 7, 13, 19, and 25 months later., Results: Higher baseline severity of hallucinations was strongly predictive of severity of delusions across all future follow-up timepoints, specifically when baseline depression was high. However, the severity of hallucinations did not change over time, nor were they predicted by baseline delusional ideation., Conclusions: These findings support the proposal that hallucinations frequently precede more severe delusional ideation, rather than the reverse sequence, particularly when depressive symptoms are present. Such longitudinal relationships provide clues to the underlying mechanisms of psychosis, highlighting one pathway for intervention., (Copyright © 2022 Elsevier B.V. All rights reserved.)

- Abstract
Aim: Avolition, or the lack of motivation, has consistently been shown to be a significant predictor of poor psychosocial outcome, with decreased overall motivation as the single strongest predictor of poor work or school outcome in first episode psychosis. This study aimed to better understand the ways in which motivation impacts work and school functioning. This study first examined the factors related to motivation in people recovering from a recent onset of psychosis, then explored the unique interrelationships between positive symptoms, stigma, and motivation and how they influence role functioning., Methods: A total of 40 participants with early psychosis were recruited for this cross-sectional design study; with a mean of 14.5 months of treatment prior to study assessment., Results: Neither experienced nor internalized stigma were related to motivation in this sample, but internalized stigma was related to work and school functioning. Positive symptoms were significantly inversely related to both work and school functioning and motivation, with mediation analyses showing that motivation significantly mediates the relationship between positive symptoms and role functioning., Conclusion: This relationship may shed light on the link between motivational deficits and work and school outcomes early in the course of psychosis, an area of critical importance for early intervention., (© 2021 John Wiley & Sons Australia, Ltd.)

- Abstract
Introduction: Chronic, non-cancer pain impacts approximately 50 million adults in the USA (20%), approximately 25% of whom receive chronic prescription opioids for pain despite limited empirical efficacy data and strong dose-related risk for opioid use disorder and opioid overdose. Also despite lack of efficacy data, there are many reports of people using cannabis products to manage chronic pain and replace or reduce chronic opioids. Here we describe the protocol for a randomised trial of the effect of cannabis, when added to a behavioural pain management and prescription opioid taper support programme, on opioid utilisation, pain intensity and pain interference., Methods: This is a pragmatic, single-blind, randomised, wait-list controlled trial that aims to enrol 250 adults taking prescription opioids at stable doses of ≥25 morphine milligram equivalents per day for chronic non-cancer pain who express interest in using cannabis to reduce their pain, their opioid dose or both. All participants will be offered a weekly, 24-session Prescription Opioid Taper Support group behavioural pain management intervention. Participants will be randomly assigned in 1:1 ratio to use cannabis products, primarily from commercial cannabis dispensaries or to abstain from cannabis use for 6 months. Coprimary outcomes are change in prescription monitoring programme-verified opioid dose and change in Pain, Enjoyment, General Activity scale scores. Secondary outcomes include quality of life, depression, anxiety, self-reported opioid dose and opioid and cannabis use disorder symptoms. All other outcomes will be exploratory. We will record adverse events., Ethics and Dissemination: This study has ethical approval by the Massachusetts General Brigham Institutional Review Board (#2021P000871). Results will be published in peer-reviewed journals and presented at national conferences., Trial Registration Number: NCT04827992., Competing Interests: Competing interests: AEE reported receiving grants from Charles River Analytics and non-financial support from Pfizer as well as serving as the chair of the data monitoring board of Karuna Pharmaceuticals outside the submitted work., (© Author(s) (or their employer(s)) 2022.

- Abstract
Food insecurity (FI) is common among people with mental illness and is associated with poor health outcomes, suggesting that equipping future psychologists with skills to address FI would be beneficial. We assessed basic FI knowledge and training among clinical psychology doctoral students in the United States and Canada. Graduate students were recruited through psychology listservs and internet postings to complete an online survey about their training experience in FI assessment and resource provision. Students (n=155) reported familiarity with the term FI but not with resources to address it. Less than 10% of students had received any training in FI assessment or resource provision as part of their graduate training, but the majority (over 80%) wished they had received this training. Clinical psychology doctoral students generally do not receive training in FI assessment and resource provision but want this training. Graduate programs should consider adding curricula to address this gap.

- Abstract
The mortality disparity for persons with schizophrenia spectrum disorders (SSDs) due to cardiovascular disease is a devastating problem. Many risk factors are present in young adults with psychosis that may be ameliorated with lifestyle interventions. Sixteen participants with SSDs enrolled in an 11-week open trial of a novel lifestyle intervention comprised of group high intensity interval training exercise and health and wellness education. The aims were to evaluate (1) feasibility and (2) impact on sedentary behavior, physical activity, nutritional knowledge, physiological outcomes, and psychological well-being at end of intervention and 11-week follow-up. Attendance rates were 70% or higher for both intervention components and participants reported increased learning about healthy eating and exercise habits. Moderate to large effect sizes were observed for physical activity and sedentary behavior with sustained improvements in sedentary behavior at follow-up. Meaningful changes were not observed in other domains.

- Abstract
Hippocampal volume loss is prominent in first episode schizophrenia (FES) and has been associated with poor clinical outcomes and with BDNF genotype; antidepressants are believed to reverse hippocampal volume loss via release of BDNF. In a 12-month, placebo-controlled add-on trial of the antidepressant, citalopram, during the maintenance phase of FES, negative symptoms were improved with citalopram. We now report results of structural brain imaging at baseline and 6 months in 63 FES patients (34 in citalopram group) from the trial to assess whether protection against hippocampal volume loss contributed to improved negative symptoms with citalopram. Hippocampal volumetric integrity (HVI) did not change significantly in the citalopram or placebo group and did not differ between treatment groups, whereas citalopram was associated with greater volume loss of the right CA1 subfield. Change in cortical thickness was associated with SANS change in 4 regions (left rostral anterior cingulate, right frontal pole, right cuneus, and right transverse temporal) but none differed between treatment groups. Our findings suggest that minimal hippocampal volume loss occurs after stabilization on antipsychotic treatment and that citalopram's potential benefit for negative symptoms is unlikely to result from protection against hippocampal volume loss or cortical thinning., (Copyright © 2021 Elsevier B.V.

- Abstract
Background: Symptoms and functioning are critical dimensions in those with schizophrenia and are typically measured using validated conventional clinical assessments. Researchers and clinicians have begun to use real-time digital methods, such as ecological momentary assessment (EMA), to assess symptoms and functioning in the moment and outside of traditional hospital and laboratory settings, which may yield more naturalistic data. Although digital methods have advantages, it is unclear whether these momentary assessments capture core aspects of symptoms and functioning., Objective: This systematic literature review aimed to evaluate the association between conventional clinical and momentary-based assessments of functioning and symptoms in individuals with schizophrenia., Methods: Studies were included if they met the following criteria: (1) written or translated into English; (2) peer-reviewed; (3) included primary quantitative data; (4) 60% of the clinical sample included persons with schizophrenia spectrum disorders; (5) included a clinical assessment of functioning and/or symptoms; (6) included active momentary assessment and/or passive data; and (7) assessed the relationship between the momentary and conventional clinical assessments., Results: A total of 49 studies (87 analyses) were included. Conventional clinical assessments of functioning and positive, negative, and depressive symptoms were related to momentary assessments of these symptom domains. Passive data was beneficial for assessing negative symptoms, but research is warranted for other domains., Conclusions: The reviewed studies highlight the utility of EMA methodologies to collect detailed data on symptoms and functioning. Such data is being used to develop more sophisticated models of schizophrenia to enhance our understanding of important mechanisms and develop targeted interventions., Competing Interests: Declaration of competing interest Dr. Browne is funded by the Department of Veterans Affairs Office of Academic Affiliations Advanced Fellowship in Geriatrics.

- Abstract
Background: Emerging data suggest cannabis use is a component cause of psychotic disorders; however, the sequence of processes accounting for this association is poorly understood. Some clues have come from studies in laboratory settings showing that acute cannabis intoxication is associated with subclinical hallucinations and delusional thinking, i.e., "psychotic experiences". Although psychotic experiences are relatively common, those that are severe and distressing are linked to an increased risk of developing a psychotic disorder. This study aimed to investigate the association between the frequency of cannabis use and psychotic experiences in young adults., Methods: 1034 U.S. college students completed questionnaires to assess: cannabis use in the past week, delusional ideation (Peters Delusions Inventory), hallucinations (Launay-Slade Hallucinations Scale-Extended), and depression (Beck Depression Inventory)., Results: Participants reporting higher rates of weekly cannabis use were more likely to report hallucinatory experiences and delusional ideation. The relationship between cannabis use and hallucinatory experiences, but not the relationship between cannabis use and delusional ideation, remained significant after controlling for levels of depression. Moreover, those who reported greater amounts of cannabis use had more distressing delusional ideas, that were held with more conviction., Conclusions: Cannabis use is linked to the presence of subclinical hallucinations and delusional ideation in U.S. college students., Competing Interests: Declaration of competing interest MF has received research support from following: Abbott Laboratories; ACADIA Pharmaceuticals; Alkermes, Inc.; American Cyanamid; Aspect Medical Systems; AstraZeneca; Avanir Pharmaceuticals; AXSOME Therapeutics; Biohaven; BioResearch; BrainCells Inc.; Bristol-Myers Squibb; CeNeRx Bio- Pharma; Cephalon; Cerecor; Clarus Funds; Clintara, LLC; Covance; Covidien; Eli Lilly and Company; EnVivo Pharmaceuticals, Inc.; Euthymics Bioscience, Inc.; Forest Pharmaceuticals, Inc.; FORUM Pharmaceuticals; Ganeden Biotech, Inc.; GlaxoSmithKline; Harvard Clinical Research Institute; Hoffman-LaRoche; Icon Clinical Research; i3 Innovus/Ingenix; Janssen R&D, LLC; Jed Foundation; Johnson & Johnson Pharmaceutical Research & Development; Lichtwer Pharma GmbH; Lorex Pharmaceuticals; Lundbeck Inc.; Marinus Pharmaceuticals; MedAvante; Methylation Sciences Inc; National Alliance for Research on Schizophrenia and Depression; National Center for Complementary and Alternative Medicine; National Coordinating Center for Integrated Medicine; National Institute of Drug Abuse; National Institute of Mental Health; Neuralstem, Inc.; NeuroRx; Novartis AG; Organon Pharmaceuticals; Otsuka Pharmaceutical Development & Commercialization; PamLab, LLC; Pfizer Inc.; Pharmacia-Upjohn; Pharmaceutical Research Associates, Inc.; Pharmavite LLC; PharmoRx Therapeutics; Photothera; Reckitt Benckiser Pharmaceuticals; Roche Pharmaceuticals; RCT Logic, LLC (formerly Clinical Trials Solutions, LLC); Sanofi-Aventis U.S. LLC; Shire; Solvay Pharmaceuticals, Inc.; Stanley Medical Research Institute; Synthelabo; Taisho Toyama Pharmaceutical Company; Takeda Pharmaceuticals U.S.A.; Tal Medical; VistaGen; and Wyeth-Ayerst Laboratories.

- Abstract
The therapeutic alliance, or client-provider relationship, has been associated with better treatment engagement and outcomes for persons with schizophrenia-spectrum disorders (SSDs) and early psychosis in some studies, but not others. We conducted a meta-analysis of the research on alliance in SSDs and early psychosis across a range of interventions and outcomes. Parallel literature searches were conducted in PubMed and PsycINFO databases for articles between inception and 6/11/2020. English-language studies were included if they evaluated the relationship between alliance and a prospective outcome (treatment engagement, medication adherence, functioning, or total, positive, negative, or depressive symptoms) in an individual clinical treatment for SSDs/early psychosis and contained analyzable data. Correlations and partial correlations were meta-analyzed with random effects models to calculate mean across-study correlations and to carry out subsequent homogeneity and moderator variable analyses. Fourteen studies consisting of 2968 participants that assessed six outcomes across six psychosocial treatments were included. Results indicated that better client-rated (r = 0.20) and other-rated (i.e., provider- or observer-rated; r = 0.25) alliance were associated with better treatment engagement. Treatment type and sample race/ethnicity, but not age, gender, or timing of alliance rating moderated the association between other-rated alliance and engagement. Further, better other-rated alliance was related to improvements in positive (r = -0.14) and negative (r = -0.22) symptoms. A strong therapeutic alliance is important for both engaging clients with SSDs and early psychosis in treatment and facilitating improvements in positive and negative symptoms. Delivery and monitoring of treatments for this population should include assessment of the therapeutic alliance from multiple perspectives., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest pertinent to this study., (Published by Elsevier B.V.)

- Abstract
Purpose/background: Hippocampal volume loss in early schizophrenia has been linked with markers of inflammation and oxidative stress, and with less response of negative symptoms. Aripiprazole has been reported to preserve hippocampal volume and to reduce inflammation., Methods/procedures: Study 1 was a 12-month multicenter randomized placebo-controlled trial of citalopram added to clinician-determined second-generation antipsychotic medication in 95 patients with first-episode schizophrenia (FES), 19 of whom received aripiprazole. We compared participants taking aripiprazole with those on other antipsychotics to determine whether those on aripiprazole had less hippocampal volume loss. We also examined peripheral biomarker data from medication-naive patients with schizophrenia receiving 8 weeks of antipsychotic treatment (n = 24) to see whether markers of inflammation and oxidative stress that previously predicted hippocampal volume differed between aripiprazole (n = 9) and other antipsychotics (study 2)., Findings/results: Aripiprazole was associated with a mean increase in hippocampal volume of 0.35% (SD, 0.80%) compared with a 0.53% decrease (SD, 1.2%) with other antipsychotics during the first year of maintenance treatment in patients with FES. This difference was significant after adjusting for age, sex, citalopram treatment, and baseline Brief Psychiatric Rating Scale score (B = 0.0079, P = 0.03). Aripiprazole was also associated with reduced concentrations of the inflammatory cytokines interleukin-8 and tumor necrosis factor (P < 0.01) during the first 8 weeks of treatment in medication-naive patients with FES., Implications/conclusions: These results suggest that aripiprazole may protect against hippocampal atrophy via an anti-inflammatory mechanism, but these results require replication in larger, randomized trials, and the clinical relevance of hippocampal volume loss is not established., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Background: In a previous study, participation in a 16-week reverse integrated care and group behavioral and educational intervention for individuals with diabetes and serious mental illness was associated with improved glycemic control (hemoglobin A
1c ) and BMI. To inform future implementation efforts, more information about the effective components of the intervention is needed., Objective: The goal of this study is to identify the aspects of the intervention participants reported to be helpful and to evaluate the predictors of outcomes., Methods: This study involved qualitative evaluation and post hoc quantitative analysis of a previous intervention. Qualitative data were collected using semistructured interviews with 69% (24/35) of the individuals who attended 1 or more group sessions and 35% (9/26) of the individuals who consented but attended no sessions. Quantitative mixed effects modeling was performed to test whether improved diabetes knowledge, diet, and exercise or higher group attendance predicted improved hemoglobin A1c and BMI. These interview and modeling outcomes were combined using a mixed methods case study framework and integrated thematically., Results: In qualitative interviews, participants identified the application of health-related knowledge gained to real-world situations, accountability for goals, positive reinforcement and group support, and increased confidence in prioritizing health goals as factors contributing to the success of the behavioral intervention. Improved knowledge of diabetes was associated with reduced BMI (β=-1.27, SD 0.40; P=.003). No quantitative variables examined were significantly associated with improved hemoglobin A1c levels., Conclusions: In this mixed methods analysis of predictors of success in a behavioral diabetes management program, group participants highlighted the value of positive reinforcement and group support, accountability for goals set, and real-world application of health-related knowledge gained. Improved diabetes knowledge was associated with weight loss., (©Kristina Schnitzer, Corrine Cather, Vanya Zvonar, Alyson Dechert, Rachel Plummer, Kelsey Lowman, Gladys Pachas, Kevin Potter, Anne Eden Evins.

- Abstract
Objective: To examine the role of race, sex, arrest history, and psychiatric diagnoses in duration of shelter tenure and housing outcomes for patients in transitional shelters., Methods: The authors performed a three-year retrospective chart review of Massachusetts Department of Mental Health (DMH) records for individuals residing in three DMH transitional homeless shelters from 2013 to 2015., Results: Race was not predictive of length of stay, initial disposition, or housing status at three to five-year follow-up. Arrest history negatively predicted initial housing placement, and diagnosis of substance use disorder predicted homelessness at follow-up. There were no differences by race in arrest history or diagnosis of substance use disorder., Conclusions: Race was not a factor in duration of shelter tenure, or in securing or maintaining housing following shelter stay. Arrest history and lifetime substance use disorder were associated with more negative outcomes following transitional shelter stay.
