Disability and schizophrenia: a systematic review of experienced psychosocial difficulties

Emotional intelligence as a predictor of functional outcomes in psychotic disorders

Psychotic disorders are associated with significant impairment in psychosocial functioning, yet mechanisms associated with this impairment remain poorly understood. Emotional intelligence, a component of social cognition, is associated with psychosocial functioning in this population. However, prior work has used relatively small samples, reported inconsistent relations between functioning domains and emotional intelligence, and inconsistently considered negative symptoms. To address these limitations, we examined the predictive ability of emotional intelligence on functional outcomes using a five-year longitudinal design. We used a large sample of individuals with and without psychotic disorder diagnoses (N = 324), a performance-based measure of emotional intelligence, and three measures of functioning (i.e., social performance, assessor-rated social and occupational functioning, self-rated functioning in independent living). Results revealed individuals diagnosed with a psychotic disorder have lower emotional intelligence than those without a history of psychosis. Emotional intelligence was associated with social performance and social and occupational functioning in both those with and without a history of psychosis. In those diagnosed with a psychotic disorder, emotional intelligence and negative symptoms better predict social performance (βEmotional = 0.36, R2delta = 0.09) and social and occupational functioning (βEmotional = 0.21, R2 = 0.03), but not self-rated functioning in independent living (βEmotional = -0.08, R2delta = 0.00), as compared to negative symptoms alone. Overall, findings support the use of emotional intelligence as a longitudinal predictor of social and occupational outcomes above and beyond negative symptoms alone. This work highlights potential, specific intervention targets for individuals with psychotic disorders.

Transcranial direct current stimulation (tDCS) enhances cognitive function in schizophrenia: A randomized double-blind sham-controlled trial

This study aimed to examine the cognitive effects of tDCS and the subjective cognitive improvement perceived by patients with schizophrenia. A total of 173 outpatients diagnosed with schizophrenia were recruited for this double-blind, randomized, placebo-controlled trial. Two different stimulation modes were applied: 2 mA 20 minutes active tDCS and sham tDCS. Ten daily sessions over 10 consecutive weekdays were applied, using a bifrontal montage (F3/F4). The Positive and Negative Syndrome Scale for Schizophrenia and the MATRICS Consensus Cognitive Battery (MCCB) were administered at baseline. The MCCB and a scale designed for measuring subjective cognitive improvement were administered to evaluate the outcomes. Post hoc comparisons revealed significant effects between the two types of interventions in Working Memory (EMM difference = 2.716, p < .001) and Neurocognition (EMM difference = 1.289, p = .007. Chi-squared tests demonstrated a significant association between subjective improvement and the treatment group, χ² (2) = 10.413, p = .005, Cramer's V = 0.295. A higher proportion of patients in active tDCS (68.6%) reported cognitive improvement compared to sham tDCS (31.4%). We concluded that tDCS can enhance cognition and generate a satisfactory perception of cognitive improvement in patients with schizophrenia.

Exploring the tipping point: a qualitative study of labour marked experiences among young people with first episode of schizophrenia

PURPOSE

Work holds significant value in the lives of most individuals, impacting various aspects such as identity, health, and the economy. However, young individuals with schizophrenia often encounter challenges in accessing and maintaining employment. Despite this, knowledge regarding their experiences with labor market is sparse. The study aimed to explore perspectives on labor market affiliation and vocational intervention in relation to quality of life and health among young people with schizophrenia.

METHODS

A qualitative approach was employed, applying individual interviews as data collection method. Twelve patients with first episode of schizophrenia were recruited from two outpatient clinics. Thematic analysis was used, following an inductive process. A user panel was established to ensure quality and relevance of the study.

RESULTS

Three key themes were identified from the analysis: 1. "Work is simultaneously rewarding and demanding", highlighting the struggle to balance the benefits of employment with the difficulties of meeting labor market requirements; 2. "Mental health, stigma and work: A complex interplay", which concerned how work simultaneously contributes to stress and reduces psychiatric symptoms; 3. "Supported employment: Facilitating work-life balance", concerning how supported employment intervention facilitated a better work-life balance, enhancing overall quality of life, under specific conditions.

CONCLUSION

Young individuals with schizophrenia are highly motivated to work, yet encounter significant barriers to labour market participation, related both to their mental health condition and societal stigma. Supported employment programmes emerge as crucial in empowering individuals with schizophrenia to navigate the complexities of the labour market while managing their mental health effectively.

Speech Mismatch Negativity (MMN) in Schizophrenia with Auditory Verbal Hallucinations

Auditory verbal hallucinations (AVH) are experienced by many individuals with schizophrenia (SZ), a neurodevelopmental disease that encumbers the quality of life and psychosocial outcome of those afflicted by it. While many hypotheses attempt to better define the etiology of AVHs in SZ, their neural profile and its moderation by current neuroleptics remains limited. The Mismatch Negativity (MMN) is an event related potential (ERP) measured from electroencephalographic (EEG) activity during the presentation of a deviance detection auditory paradigm. The neural regions and activity underlying the generation of the MMN include the primary auditory cortex and the prefrontal cortex which are regions also found to be activated during the experience of AVHs. Decreased MMN amplitudes have been robustly noted in SZ patients during the presentation of MMN tasks using auditory tones. However, the MMN generation to speech stimuli has not been extensively examined in SZ nor in relation to AVHs. The primary objective of this study was to examine the MMN to five speech-based deviants in SZ patients and healthy controls. Second, we assessed MMN features with AVH characteristics in 19 SZ patients and 21 HC. While AVH features did not correlate with measures of MMN, we found decreased MMN amplitudes to speech-based frequency and vowel change deviants in SZ patients compared to HC potentially reflecting deficiencies in basic speech processing mechanisms.

Obsessive-compulsive symptoms relating to psychosocial functioning for people with schizophrenia, schizoaffective disorder, or bipolar disorder

To assess the psychosocial functioning concerning obsessive-compulsive symptoms (OCS) and/or obsessive-compulsive disorder (OCD) comorbidity in people with schizophrenia, schizoaffective disorder, or bipolar disorder diagnosed in a large case register database in Southeast London. Data were retrieved from the South London and Maudsley NHS Foundation Trust Biomedical Research Centre (SLaM BRC) register using Clinical Record Interactive Search (CRIS) system, a platform allowing research on full but de-identified electronic health records for secondary and tertiary mental healthcare services. Information of schizophrenia, schizoaffective disorder, bipolar disorder diagnosis and OCS/OCD status was ascertained from structural or free-text fields through natural language processing (NLP) algorithms based on artificial intelligence techniques during the observation window of January 2007 to December 2016. Associations between comorbid OCS/OCD and recorded Health of the Nation Outcome Scales (HoNOS) for problems with activities of daily living (ADLs), living conditions, occupational and recreational activities, and relationships were estimated by logistic regression with socio-demographic confounders controlled. Of 15,412 subjects diagnosed with schizophrenia, schizoaffective disorder, or bipolar disorder, 2,358 (15.3%) experienced OCS without OCD, and 2,586 (16.8%) had OCD recorded. The presence of OCS/OCD was associated with more problems with relationships (adj.OR = 1.34, 95% CI: 1.25-1.44), ADLs (adj.OR = 1.31, 95%CI: 1.22-1.41), and living conditions (adj.OR = 1.31, 95% CI: 1.22-1.41). Sensitivity analysis revealed similar outcomes. Comorbid OCS/OCD was associated with poorer psychosocial functioning in people with schizophrenia, schizoaffective disorder, or bipolar disorder. This finding highlights the importance of identification and treatment of comorbid OCS among this vulnerable patient group.

The mediating effect of self-efficacy on the relationship between self-care ability and disability level in older adult patients with chronic diseases

Objective

This study investigates the mediating effect of self-efficacy on the relationship between self-care ability and disability level in older adult patients with chronic diseases.

Methods

A convenience sampling method was used to select 372 older adult patients with chronic diseases from five tertiary hospitals in Chengdu, Sichuan Province. General demographic information was collected using a questionnaire, and self-efficacy, self-care ability, and disability were assessed using standardized scales. Data were analyzed using SPSS 26.0, and the PROCESS macro was employed to test the mediating effect of self-efficacy.

Results

The mean score for self-efficacy was 26.09 ± 7.20, for self-care ability was 113.19 ± 23.31, and for disability was 154.19 ± 29.32. Self-efficacy was positively correlated with self-care ability (r = 0.73, p < 0.001. and negatively correlated with disability (r = -0.84, p < 0.001. and self-care ability and disability (r = -0.91, p < 0.001.. The indirect effect of self-efficacy on the relationship between self-care ability and level of disability was -0.03 (95% CI -0.08 to -0.04), accounting for 16.67% of the total effect.

Conclusion

Self-efficacy partially mediates the relationship between self-care ability and disability in older adult patients with chronic conditions. Healthcare providers can improve self-care behaviours and self-efficacy in older adult patients through effective interventions to reduce the incidence of disability.

Knowledge, behavior, and effect of health messaging during the first Indian lockdown for COVID-19

Background

Coronavirus disease (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was declared a global pandemic in March 2020, affecting certain health measures. Precautionary hygiene measures of hand washing, mask-wearing, and social distancing were advocated and disseminated to the public through different government machinery.

Aim

The current study explored if government messaging had an impact on the knowledge of COVID-19 and the necessary precautionary behaviors in three groups: persons with past suicide attempts (PSA), persons with schizophrenia (SZ), and the general population during the first lockdown (March to May 2020).

Materials and Methods

A cross-sectional 22-item questionnaire was designed to assess "precautionary knowledge," "precautionary behaviors," "living circumstances," and "tobacco and alcohol consumption" before and during the first Indian lockdown. PSA and SZ were contacted telephonically, while for the general population, the survey was adapted into Google Forms and circulated as a WhatsApp link. Inclusion criteria were both genders, 18-65 years, and Indians residing in India.

Results

No differences among PSA, SZ, and the general population were reported in the knowledge for the lockdown and behavior for "hand washing," "mask-wearing," and "frequency of going outdoors." Almost 15% of the general population moved back home during the lockdown. A significantly higher frequency of alcohol consumption was reported by the general population both before and during the lockdown compared with PSA and SZ.

Conclusion

Appropriate COVID-19 knowledge and behavior were seen in PSA, SZ, and the general population. Thus, government-mandated behaviors for COVID-19 were adhered to by all three groups. The study demonstrates the effectiveness of the government's health messaging among people with severe mental illnesses in times of a novel worldwide health crisis.

Exploring Characteristics of Homicide Offenders With Schizophrenia Spectrum Disorders Via Machine Learning

The link between schizophrenia and homicide has long been the subject of research with significant impact on mental health policy, clinical practice, and public perception of people with psychiatric disorders. The present study investigates factors contributing to completed homicides committed by offenders diagnosed with schizophrenia referred to a Swiss forensic institution, using machine learning algorithms. Data were collected from 370 inpatients at the Centre for Inpatient Forensic Therapy at the Zurich University Hospital of Psychiatry. A total of 519 variables were explored to differentiate homicidal and other (violent and non-violent) offenders. The dataset was split employing variable filtering, model building, and selection embedded in a nested resampling approach. Ten factors regarding criminal and psychiatric history and clinical factors were identified to be influential in differentiating between homicidal and other offenders. Findings expand the research on influential factors for completed homicide in patients with schizophrenia. Limitations, clinical relevance, and future directions are discussed.

A Network Model of Health-Related Changes after a Lifestyle-Enhancing Treatment in Patients with Severe Mental Illness: the MULTI Study VI

Background/Objective

The effects of lifestyle interventions on physical and mental health in people with severe mental illness (SMI) are promising, but its underlying mechanisms remain unsolved. This study aims to examine changes in health-related outcomes after a lifestyle intervention, distinguishing between direct and indirect effects.

Method

We applied network intervention analysis on data from the 18-month cohort Multidisciplinary Lifestyle enhancing Treatment for Inpatients with SMI (MULTI) study in 106 subjects (62% male, mean age=54.7 (SD=10.8)) that evaluated changes in actigraphy-measured physical activity, metabolic health, psychopathology, psychosocial functioning, quality of life and medication use after MULTI (n=65) compared to treatment as usual (n=41).

Results

MULTI is directly connected to decreased negative symptoms and psychotropic medication dosage, and improved physical activity and psychosocial functioning, suggesting a unique and direct association between MULTI and the different outcome domains. Secondly, we identified associations between outcomes within the same domain (e.g., metabolic health) and between the domains (e.g., metabolic health and social functioning), suggesting potential indirect effects of MULTI.

Conclusions

This novel network approach shows that MULTI has direct and indirect associations with various health-related outcomes. These insights contribute to the development of effective treatment strategies in people with severe mental illness.

Schizophrenia spectrum disorders in India: A population-based study

Introduction

Schizophrenia spectrum disorders represent a significant global health concern, contributing significantly to the global burden of disease. The National Mental Health Survey (NMHS) of India, conducted between 2015 and 2016, investigated the prevalence and epidemiological correlates of schizophrenia spectrum disorders in India.

Materials and Methods

The NMHS conducted a population-based cross-sectional study in 12 Indian states from 2015 to 2016, encompassing 34,802 adults. The overall study design of the NMHS was a multistage, stratified, random cluster sampling technique, incorporating random selection based on probability proportion to size at each stage. The Mini-International Neuropsychiatric Interview 6.0 was used for psychiatric diagnoses, disability was assessed using Sheehan's disability scale, and the illness-related socioeconomic impact was assessed using a questionnaire based on the World Health Organization Disability Assessment Schedule 2.0. Firth penalized logistic regression was employed to understand the correlates of current schizophrenia spectrum disorder.

Results

The study found a lifetime prevalence of schizophrenia spectrum disorders at 1.41%, with a current prevalence of 0.42%. A substantial treatment gap of 72% existed for current cases, rising to 83.3% in urban non-metro areas. The penalized logistic regression revealed that the age group category of 30-49 years, unemployed status, and lower education level had higher odds of association with schizophrenia spectrum disorders.

Conclusion

The primary finding of this study is a lifetime prevalence of 1.41%, a current prevalence of 0.42%, and a substantial treatment gap of 72%. Addressing this treatment gap and holistic intervention is crucial for reducing the socioeconomic impact of this disorder. Strengthening the National Mental Health Program and implementing community-based rehabilitation are essential first steps in this direction.

Digital tools to support mental health: a survey study in psychosis

BACKGROUND

There is a notable a gap between promising research findings and implementation of digital health tools. Understanding and addressing barriers to use is key to widespread implementation.

METHODS

A survey was administered to a self-selecting sample in-person (n = 157) or online (n = 58), with questions examining: i) ownership and usage rates of digital devices among people with psychosis; ii) interest in using technology to engage with mental health services; and iii) facilitators of and barriers to using digital tools in a mental healthcare context.

RESULTS

Device ownership: Virtually all participants owned a mobile phone (95%) or smartphone (90%), with Android phones slightly more prevalent than iPhones. Only a minority owned a fitness tracker (15%) or smartwatch (13%). Device ownership was significantly lower in unemployed people and those without secondary education. Device cost and paranoid ideation were barriers to ownership. Technology and mental health services: Most participants (88%) said they would willingly try a mental health app. Symptom monitoring apps were most popular, then appointment reminders and medication reminders. Half the sample would prefer an app alongside face-to-face support; the other half preferred remote support or no other mental health support. Facilitators: Participants thought using a mental health app could increase their understanding of psychosis generally, and of their own symptoms. They valued the flexibility of digital tools in enabling access to support anywhere, anytime. Barriers: Prominent barriers to using mental health apps were forgetting, lack of motivation, security concerns, and concerns it would replace face-to-face care. Overall participants reported no substantial effects of technology on their mental health, although a quarter said using a phone worsened paranoid ideation. A third used technology more when psychotic symptoms were higher, whereas a third used it less. Around half used technology more when experiencing low mood.

CONCLUSIONS

Our findings suggest rapidly increasing device ownership among people with psychosis, mirroring patterns in the general population. Smartphones appear appropriate for delivering internet-enabled support for psychosis. However, for a sub-group of people with psychosis, the sometimes complex interaction between technology and mental health may act as a barrier to engagement, alongside more prosaic factors such as forgetting.

Quality of Life of people with Schizophrenia: A meta-analysis

BACKGROUND

Schizophrenia is a severe, chronic mental disorder that causes many psychosocial problems. In order to reveal these problems, it is necessary to measure the quality of life of people with schizophrenia.

AIM

The aim of this meta-analysis is to compare the quality of life of people with schizophrenia and healthy subjects.

METHODS

Literature search was conducted in the Web of Science Core Collection database including the dates of January 2000 and March 2021. The systematic search provided 464 potentially relevant studies. The final sample consisted of 18 studies.

RESULTS

The results of using a random effects model for analysis indicated that schizophrenia subjects showed considerably lower quality of life scores compared to healthy controls.

CONCLUSION

Determining the quality of people with schizophrenia will help us to create effective psychosocial intervention programs.

The relationship between self-esteem and mental disability in patients with schizophrenia: the mediating role of resilience and the moderating role of gender

This study aims to verify the mediating role of resilience between self-esteem and mental disability and to analyze the moderating role of gender in the relationship between resilience and mental disability in patients with schizophrenia. Patients with schizophrenia have been selected from Harbin Psychiatric (Baiyupao) Hospital and Daqing Third Hospital in Heilongjiang Province from January to December 2021. The study recruited a total of 220 patients with schizophrenia, including 120 males and 100 females to measure their self-esteem, resilience and mental disability. The results were as follows: Self-esteem and resilience are important protective factors that have a buffering effect on mental disability. The mediating effect of resilience on self-esteem and mental disability is stronger in males than in females. The results provide new ideas for delaying mental disability and for formulating intervention programs and applying them to clinical practice. The study indicates that psychiatric medical staff should not only treat the patients with schizophrenia psychotic symptoms but also improve their self-esteem and resilience through effective intervention to reduce the occurrence of mental disability.

Raphe Nuclei Echogenicity and Diameter of Third Ventricle in Schizophrenia Measured by Transcranial Sonography

Introduction

Serotonergic system hyperactivity at 5-HT2A receptors on glutamate neurons in the cerebral cortex is one of the pathways that is theoretically linked to psychosis. In addition to neurotransmitter dysfunction, volumetric studies have revealed the loss of cortical gray matter and ventricular enlargement in patients with schizophrenia, although there is no case-control research on patients with schizophrenia to evaluate echogenicity of raphe nuclei (RN) or diameter of the third ventricle (DTV). To address these issues, the present study assessed midbrain RN, as the main source of brain serotonin, and DTV, as an index of atrophy, by transcranial sonography (TCS) in a group of patients with schizophrenia.

Methods

Thirty patients with schizophrenia and 30 controls were assessed by TCS for RN echogenicity and DTV. TCS was done through a temporal bone window via a phased-array ultrasound using a 2.5 MHz transducer in a depth of 14-16 cm. RN echogenicity was assessed by a semi-quantitative visual scale and DTV was measured in the thalamic plane.

Results

Twenty-three patients (76.5%) and 15 controls (50 %) showed hypoechogenicity of RN, which was marginally significant (P=0.06). DTV was on average larger in the experimental group (0.388 cm vs 0.234 cm, P<0.001).

Conclusion

Increased DTV in patients with schizophrenia is consistent with previous neuroimaging findings. However, marginally lower echogenicity of midbrain RN on TCS in schizophrenia is a new finding that supports the serotonin hypothesis of schizophrenia.

Highlights

30 patients with schizophrenia and 30 controls were assessed by TCS for RN echogenicity and diameter of the third ventricle (DTV).23 patients (76.5%) and 15(50 %) controls showed hypoechogenicity of RN which was marginally significant (P=0.06)DTV was in average larger in the patient's group (0.388 cm vs 0.234 cm, P<0.001).Increased DTV in the patients with schizophrenia is consistent with previous neuroimaging findingsMarginally lower echogenicity of midbrain RN on TCS in schizophrenia is a new finding that supports the serotonin hypothesis of schizophrenia.

Plain Language Summary

Schizophrenia is a disabling psychiatric disorder. Various neurotransmitters have a role in the pathophysiology of schizophrenia including Serotonin and dopamine. This study assessed the echogenicity of raphe nuclei (RN), as the main source of brain serotonin, and the diameter of the third ventricle (DTV), as an index of atrophy, by transcranial sonography (TCS) method in 30 patients with schizophrenia and 30 healthy controls. Based on the results, 23 patients (76.5%) and 15 controls (50%) showed decreased echogenicity of RN. There was a significant difference between the two groups in terms of the echogenicity of RN. Moreover, the DTV diameter was significantly larger in patients compared to controls.

Establishing a Care Continuum for Cardiometabolic Conditions for Patients with Serious Mental Illness

PURPOSE OF REVIEW

Addressing cardiometabolic risk factors in persons with serious mental illness requires early screening and proactive medical management in both medical and mental health settings.

RECENT FINDINGS

Cardiovascular disease remains the leading cause of death for persons with serious mental illness (SMI), such as schizophrenia or bipolar disorder, much of which is driven by a high prevalence of metabolic syndrome, diabetes, and tobacco use. We summarize barriers and recent approaches to screening and treatment for metabolic cardiovascular risk factors within physical health and specialty mental health settings. Incorporating system-based and provider-level support within physical health and psychiatric clinical settings should contribute to improvement for screening, diagnosis, and treatment for cardiometabolic conditions for patients with SMI. Targeted education for clinicians and leveraging multi-disciplinary teams are important first steps to recognize and treat populations with SMI at risk of CVD.

Psychometric and clinical evaluation of schizophrenia remission criteria in outpatients with psychotic disorders

BACKGROUND

Psychotic disorders such as schizophrenia have debilitating effects on health and functioning. Given symptomatic remission's recent emergence as a viable treatment goal, the Remission in Schizophrenia Working Group's criteria (RSWG-cr), based on eight items from the Positive and Negative Syndrome Scale (PANSS-8), are frequently used in clinical and research settings. Against that background, we sought to evaluate the PANSS-8's psychometric properties and examine the RSWG-cr's clinical validity among outpatients in Sweden.

METHODS

Cross-sectional register data were collected from outpatient psychosis clinics in Gothenburg, Sweden. Following confirmatory and exploratory factor analyses of PANSS-8 data (n = 1,744) to assess the PANSS-8's psychometric properties, internal reliability was evaluated using Cronbach's alpha. Next, 649 of the patients were classified according to the RSWG-cr and their clinical and demographic characteristics compared. Binary logistic regression was used to estimate odds ratios (OR) and assess each variable's impact on remission status.

RESULTS

The PANSS-8 showed good reliability (α = .85), and the 3D model of psychoticism, disorganization, and negative symptoms presented the best model fit. According to the RSWG-cr, 55% of the 649 patients were in remission; they were also more likely to live independently, be employed, not smoke, not take antipsychotics, and have recently received a health interview and physical examination. Patients living independently (OR = 1.98), who were employed (OR = 1.89), who were obese (OR = 1.61), and who had recently received a physical examination (OR = 1.56) also had an increased likelihood of remission.

CONCLUSIONS

The PANSS-8 is internally reliable, and, according to the RSWG-cr, remission is associated with variables of interest for patients' recovery, including living independently and being employed. Although our findings from a large, heterogeneous sample of outpatients reflect everyday clinical practice and reinforce past observations, the directions of those relationships need to be assessed in longitudinal studies.

Association Between Childhood Adversity and Functional Outcomes in People With Psychosis: A Meta-analysis

BACKGROUND AND HYPOTHESIS

Despite the accepted link between childhood adversity (CA) and psychotic disorders, evidence on the relationship between CA and poor functional outcome remains less consistent and has never been reviewed quantitatively. The aim of this meta-analysis was to systematically examine the association between CA and functional outcomes in people with psychotic disorders.

STUDY DESIGN

The study protocol was registered on the International Prospective Register of Systematic Reviews (CRD42021254201). A search was conducted across EMBASE, MEDLINE, PsycINFO, and Cochrane Libraries (CENTRAL) using search terms related to psychosis; CA (general, sexual abuse, physical abuse, emotional abuse, physical neglect, and emotional neglect); and functional outcomes (social, occupational, and general functioning [GF]). We conducted random-effects models, sensitivity and heterogeneity analyses, meta-regressions, and we assessed quality.

STUDY RESULTS

Our meta-analysis comprised 35 studies, including 10 568 cases with psychosis. General CA was negatively associated with GF (28 studies; r = -0.109, 95%CI = -0.161 to -0.05, P < .001), with greater effects in prospective data (10 studies; r = -0.151, 95% CI = -0.236 to -0.063, P = .001). General CA was also associated with social functioning (r = -0.062, 95% CI = -0.120 to -0.004, P = .018) but not occupational outcomes. All CA subtypes except sexual abuse were significantly associated with GF, with emotional and physical neglect showing the largest magnitudes of effect (ranging from r = -0.199 to r = -0.250).

CONCLUSIONS

This meta-analysis provides evidence for a negative association between general CA, specific subtypes, and general and social functional outcomes in people with psychosis.

High Risk, High Dose?-Pharmacotherapeutic Prescription Patterns of Offender and Non-Offender Patients with Schizophrenia Spectrum Disorder

Compared to acute or community settings, forensic psychiatric settings, in general, have been reported to make greater use of antipsychotic polypharmacy and/or high dose pharmacotherapy, including overdosing. However, there is a scarcity of research specifically on offender patients with schizophrenia spectrum disorders (SSD), although they make up a large proportion of forensic psychiatric patients. Our study, therefore, aimed at evaluating prescription patterns in offender patients compared to non-offender patients with SSD. After initial statistical analysis with null-hypothesis significance testing, we evaluated the interplay of the significant variables and ranked them in accordance with their predictive power through application of supervised machine learning algorithms. While offender patients received higher doses of antipsychotics, non-offender patients were more likely to receive polypharmacologic treatment as well as additional antidepressants and benzodiazepines. To the authors' knowledge, this is the first study to evaluate a homogenous group of offender patients with SSD in comparison to non-offender controls regarding patterns of antipsychotic and other psychopharmacologic prescription patterns.

Early intervention in psychosis in emerging countries: Findings from a first-episode psychosis programme in the Ribeirão Preto catchment area, southeastern Brazil

AIM

People presenting with first-episode psychosis (FEP) can benefit from early intervention programmes. However, such programmes are scarce in low- and middle-income countries (LMICs). In Brazil, there are a few programmes, but they are unequally distributed across the country. We aimed to describe the implementation and performance of the Ribeirão Preto Early Intervention in Psychosis Programme (Ribeirão Preto-EIP), an outpatient service for patients presenting with FEP residing in the Ribeirão Preto catchment area in Southeastern Brazil.

METHODS

A detailed description of the service, staff and theoretical framework was compiled. Furthermore, a retrospective cohort study of patients attending the programme throughout 4 years (2015-2018) was conducted. Data were obtained by analysing the medical records of all patients, and sociodemographic and diagnostic stability information for this period was recorded.

RESULTS

The Ribeirão Preto-EIP had 358 new referrals during the study period. Among them, 237 patients were assessed for an average (median) duration of 14 months. Most patients were male (64.1%) and single (84.8%). The median age was 23.5 years (range, 9-86 years). Schizophrenia was the main diagnosis (43.4%), followed by substance-induced (25.7%) and affective (18.6%) psychosis. Referrals occurred from emergency, inpatient, community-based mental health and primary care services.

CONCLUSIONS

Programmes such as the Ribeirão Preto-EIP demonstrate that early intervention in psychosis is feasible in LMICs despite significant challenges for their access and integration in the health system. Strategic scale-up policies could be undertaken to offer better short- and long-term outcomes for individuals presenting with FEP and their families.

Effects of endocannabinoid system modulation on social behaviour: A systematic review of animal studies

There is a clear link between psychiatric disorders and social behaviour, and evidence suggests the involvement of the endocannabinoid system (ECS). A systematic review of preclinical literature was conducted using MEDLINE (PubMed) and PsychINFO databases to examine whether pharmacological and/or genetic manipulations of the ECS alter social behaviours in wildtype (WT) animals or models of social impairment (SIM). Eighty studies were included. Risk of bias (RoB) was assessed using SYRCLE's RoB tool. While some variability was evident, studies most consistently found that direct cannabinoid receptor (CBR) agonism decreased social behaviours in WT animals, while indirect CBR activation via enzyme inhibition or gene-knockout increased social behaviours. Direct and, more consistently, indirect CBR activation reversed social deficits in SIM. These CBR-mediated effects were often sex- and developmental-phase-dependent and blocked by CBR antagonism. Overall, ECS enzyme inhibition may improve social behaviour in SIM, suggesting the potential usefulness of ECS enzyme inhibition as a therapeutic approach for social deficits. Future research should endeavour to elucidate ECS status in neuropsychiatric disorders characterized by social deficits.

Validity and usefulness of the short form of the Drinking Motives Questionnaire Revised (DMQ-R SF) among patients with schizophrenia

OBJECTIVE

Drinking motives are considered to be major predictors of alcohol consumption and alcohol-related problems. However, these motives have been poorly investigated in patients with schizophrenia. The aim of the present study among patients with schizophrenia was twofold: 1) assess the validity of the short form of the Drinking Motives Questionnaire-Revised (DMQ-R SF); and 2) investigate the relationship between drinking motives and comorbid alcohol use disorder (AUD).

METHOD

A total of 179 patients with schizophrenia were approached to participate in the study. DSM-5 criteria were used to identify patients with comorbid AUD (AUD+; n = 42) and non-abstainers patients without comorbid AUD (AUD-; n = 71).

RESULTS

A confirmatory factor analysis conducted on items of the DMQ-R SF for the whole sample revealed adequate goodness-of-fit values, while internal consistency indices were globally satisfactory. Group comparisons revealed higher use of alcohol and other substances, as well as stronger drinking motives among AUD + patients, while groups were comparable concerning clinical features of schizophrenia, including psychotic symptom dimensions and severity. Regression analysis showed that the Alcohol Use Disorder Identification Test score was significantly associated with two internal drinking motives: enhancement and coping.

CONCLUSIONS

Findings suggest that the DMQ-R SF is a reliable tool for assessing drinking motives among patients with schizophrenia. Enhancement and coping motives seem to play a major role in comorbid AUD among these patients. Community-based and clinical treatment programs should take the drinking motives of dual-diagnosis patients into consideration, in order to improve their outcomes.

Brief ICF Core Set for Schizophrenia: Development of Criteria for Assessing the Degree of Disability

Introduction

A paradigm shift in the assessment and rehabilitation of people with schizophrenia is needed, with an integrative perspective rather than a simple focus on the underlying symptomatology. To this end, it is essential to adopt integrated and continuous care focused on the person in his/her context. As a contribution, the Brief International Classification of Functioning, Disability and Health (ICF) Core Set for schizophrenia has been developed by international experts. The present study aims to develop a scale to classify the degree of disability for each of the categories of the Brief ICF Core Set for schizophrenia.

Methods

The classification criteria were first developed by the researchers and then submitted for assessment by national experts in the area of schizophrenia, using the modified e-Delphi method.

Results

Two rounds of questions were asked, and a consensus was reached on the development of the Schizophrenia Functioning Core Set, consisting of all categories of the Brief ICF Core Set for schizophrenia and the criteria for classifying the degree of disability. The degree of agreement of the experts was greater than 90% in all categories.

Conclusion

The construction of the disability grading criteria was based on the characteristics of schizophrenia as defined in DSM-V, as well as on some functional assessment scales specifically for this disorder. The development of the Schizophrenia Functioning Core Set allows for reducing the subjectivity in the assessment of the functioning of people with schizophrenia, standardizing the application of criteria to assign the degree of disability in each of the categories.

Course and predictors of disability in Thai patients with schizophrenia: A 2-year, multi-center, prospective, observational study

PURPOSE

This 2-year, multi-center, prospective, observational study aimed to describe the course and examine baseline characteristics for predicting disability in Thai patients with schizophrenia.

METHODS

Participants were patients with schizophrenia aged 18-65 years receiving treatment in five tertiary hospitals. Disability was defined by a score of 10 or more of the 12-item World Health Organization Disability Assessment Schedule, version 2.0 (12-item WHODAS 2.0). Other data being collected included socio-demographic data, course of illness, antipsychotics, antipsychotic drug attitudes, behavioral/psychiatric symptoms, alcohol use, social supports, and quality of life at five visits, including weeks 0 (baseline), 24, 48, 72, and 96.

RESULTS

Of the 158 enrolled patients, we analyzed the data of 119 participants who were reassessed at least once during the follow-up. These 119 participants (70% male) had median age and age at psychotic onset of 38 and 22 years, respectively. Disability was found in 43 (36.1%) participants at baseline and 72 (64.7%) participants at week 96. The median [interquartile ranges] WHODAS scores at five time points were 6 [3-12], 9 [4-13], 10 [6-10], 10 [4-10], and 10 [6-10], respectively (p < 0.001). The multivariate logistic regression analysis revealed that duration of psychosis (adjusted odds ratio = 1.08, 95%CI = 1.04 - 1.14, p = 0.001) and depression (adjusted odds ratio = 3.54, 95%CI = 1.14 - 11.06, p = 0.029) at baseline predicted 2-year disability.

CONCLUSIONS

Thai patients with schizophrenia had an increase in disability over a 2-year follow-up period. Duration of psychosis and depression were predictors of disability in these patients.

Changes in social functioning over the course of psychotic disorders-A meta-analysis

In this meta-analysis we investigated changes in social functioning and its moderators in patients with a psychotic disorder but different durations of illness at baseline. We included longitudinal studies assessing the course of five domains of social functioning in patients with a psychotic disorder. Effect sizes of change between baseline and follow-up within these domains were analyzed in four subgroups based on durations of psychotic disorder at baseline: less than 2 years, between 2 and 5 years, between 5 and 10 years, and more than 10 years. The influence of baseline confounders was analyzed using meta-regression and sensitivity analysis. We included 84 studies analyzing 33,456 participants. We found a medium improvement (d = 0.60) in overall social functioning over time, with a greater improvement for studies investigating patients with a duration of illness of less than 5 years. We found minor improvement in specific domains of social functioning, such as vocational functioning (d = 0.31), prosocial behavior (d = 0.36), activities (d = 0.15), and independence (d = 0.25). Improvement in social functioning was associated with lower baseline levels of negative symptoms, higher baseline levels of quality of life, and, specifically, improved vocational functioning, with rehabilitation and combined treatment. Social functioning in patients with psychotic disorders improves over time, especially for patients with shorter illness durations. Reduction of negative symptoms and improving quality of life might reinforce improvement of social functioning.

Stress, Schizophrenia, and Violence: A Machine Learning Approach

This study employs machine learning algorithms to examine the causes for engaging in violent offending in individuals with schizophrenia spectrum disorders. Data were collected from 370 inpatients at the Centre for Inpatient Forensic Therapy, Zurich University Hospital of Psychiatry, Switzerland. Based on findings of the general strain theory and using logistic regression and machine learning algorithms, it was analyzed whether accumulation and type of stressors in the inpatients' history influenced the severity of an offense. A higher number of stressors led to more violent offenses, and five types of stressors were identified as being highly influential regarding violent offenses. Our findings suggest that an accumulation of stressful experiences in the course of life and certain types of stressors might be particularly important in the development of violent offending in individuals suffering from schizophrenia spectrum disorders. A better understanding of risk factors that lead to violent offenses should be helpful for the development of preventive and therapeutic strategies for patients at risk and could thus potentially reduce the prevalence of violent offenses.

Environmental Barriers and Functional Outcomes in Patients with Schizophrenia in Taiwan: The Capacity-Performance Discrepancy

Environmental factors are crucial determinants of disability in schizophrenic patients. Using data from the 2014-2018 Certification of Disability and Care Needs dataset, we identified 3882 adult patients (46.78% females; age, 51.01 ± 13.9 years) with schizophrenia. We found that patients with severe schizophrenia had lower capacity and performance than those with moderate schizophrenia. The chances of having an access barrier to environmental chapter 1 (e1) products and technology in moderate schizophrenic patients and in severe schizophrenic patients were 29.5% and 37.8%, respectively. Logistic regression analyses demonstrated that the performance score was related to accessibility barriers in the categories described in e1, with adequate fitness of models in category e110 for personal consumption, e115 for personal usage in daily living activities, and e120 for personal outdoor and indoor mobility and transportation. Furthermore, the capacity-performance discrepancy was higher in moderate schizophrenic patients with accessibility barriers in the e110, e115, and e120 categories than that in moderate schizophrenic patients without accessibility barriers. However, severe schizophrenic patients with category e120 accessibility barriers were prone to a lower discrepancy, with institutional care a potentially decreasing factor. In conclusion, providing an e1 barrier-free environment is necessary for patients with schizophrenia to decrease their disability.

Taurine prevents MK-801-induced shoal dispersion and altered cortisol responses in zebrafish

Schizophrenia is a chronic neuropsychiatric disorder characterized by a shortened lifespan and significant impaired social and vocational functioning. Schizophrenic patients can present hypothalamic-pituitary-adrenal (HPA) axis dysfunctions and cortisol dysregulation, which play an important role on the etiology onset, exacerbation, and relapsing of symptoms. Based on its intrinsic neuroprotective properties, taurine is considered a promising substance with beneficial role on various brain disorders, including schizophrenia. Here, we evaluated the effects of taurine on shoaling behavior and whole-body cortisol levels in zebrafish treated with dizocilpine (MK-801), which elicits schizophrenia-like phenotypes in animal models. Briefly, zebrafish shoals (4 fish per shoal) were exposed to dechlorinated water or taurine (42, 150, or 400 mg/L) for 60 min. Then, saline (PBS, pH 7.4 or 2.0 mg/kg MK-801) were intraperitoneally injected and zebrafish behavior was recorded 15 min later. In general, MK-801 disrupted shoaling behavior and reduced whole-body cortisol levels in zebrafish. All taurine pretreatments prevented MK-801-induced increase in shoal area, while 400 mg/L taurine prevented the MK-801-induced alterations in neuroendocrine responses. Moreover, all taurine-pretreated groups showed increased geotaxis, supporting a modulatory role in the overall dispersion pattern of the shoal. Collectively, our novel findings show a potential protective effect of taurine on MK-801-induced shoal dispersion and altered neuroendocrine responses, fostering the use of zebrafish models to assess schizophrenia-like phenotypes.

Culturally Adapted Psychoeducation among Family Caregivers of Schizophrenic Clients: A Scoping Review

Background: As psychoeducation was originally developed from Western, this intervention should be integrated with a culture to obtain effective outcomes. However, how culturally adapted psychoeducation on family caregivers of schizophrenic client developed in previous studies has not been systematically documented. The purpose of this review was to map culturally adapted psychoeducation in previous studies. Methods: This scoping review followed Arksey & O'Malley approach. Inclusion criteria including family caregiver, culture, psychoeducation, schizophrenia. Non-primary and non-experiment studies, non-English language and non-free articles were excluded. Advanced search technique used keywords family caregiver, culture, psychoeducation, schizophrenia on CINAHL, PubMed, and PsycInfo databases. Screening was done by checking duplication, title, and abstract. Full text of relevant articles was read in detail to select eligible articles. Selection results were described in the PRISMA flow chart. Data were analyzed after these were extracted and resumed on the table.   Result: A total of 8 studies were included in this review. More than half of  articles used randomized control trial (RCT) but these studies did not conduct follow up. Most of studies were  in Asia (6) and it conducted  in the outpatient department (6). Almost all studies modified multifamily group psychoeducation with culture theories. The longest duration of intervention was 12 months. Multidiscipline health professional delivered the intervention and most of the were psychiatrist. Coping was the most family caregiver outcomes in reviewed studies. Conclusion: In conclusion, limited studies were obtained in various ethnics and ways. Further studies need to measure effectiveness of the intervention in long term effect.  

Associations of living arrangements with symptoms and functioning in schizophrenia

BACKGROUND

Living arrangements and accommodation are closely related, but no study had concurrently investigated their associations with outcomes in schizophrenia. This study seeks to describe and compare socio-demographic, clinical and functioning profiles of people with schizophrenia in different living arrangements and accommodation, and to examine the associations of living arrangements and accommodation with symptomatic remission and functioning.

METHODS

Community dwelling outpatients with schizophrenia (n = 276) were inquired on living arrangements, accommodation, socio-demographics and assessed on the Positive and Negative Syndrome Scale (PANSS) and the Social and Occupational Functioning Scale (SOFAS). Socio-demographics, symptoms and functioning of outpatients in different living arrangements and accommodation were compared. Symptomatic remission was investigated using logistic regression with living arrangements, socio-demographics and clinical variables as independent variables. Functioning was investigated using multiple regression with the same set of independent variables and the addition of PANSS factors. The same analyses were conducted with accommodation as independent variable.

RESULTS

185 (67.03%) participants lived with family and 195 (70.65%) participants lived in owned accommodation. People living with their spouses had significantly higher SOFAS, lower PANSS Total and PANSS Positive than people living with family, independently, or in rehabilitation centres. They also had lower PANSS Negative than people living with family and a higher likelihood to have achieved symptomatic remission. Types of accommodation was not associated with symptoms, symptomatic remission, and functioning.

CONCLUSION

Living arrangements, but not types of accommodation, were associated with symptoms and functioning in schizophrenia. Family education and support is important to help maintain a conducive environment for people with schizophrenia. People living independently may need more support.

Functioning Problems in Persons with Schizophrenia in the Russian Context

Assessing functionality in schizophrenia from a biopsychosocial perspective is essential to generate treatments that respond to the needs of the individual in his/her context. This research aims to assess the prevalence of functioning problems and their association with socio-demographic and clinical variables in a sample of Russian individuals with schizophrenia, using the International Classification of Functioning, Disability, and Health as a framework. An empirical cross-sectional study assessed the functioning of 40 individuals with schizophrenia using the International Classification of Functioning, Disability, and Health Core Set for schizophrenia. For the Body functions component, the highest prevalence of problems was found in b144 Memory functions (75%) and b140 Attention functions (70%). In the Activities and participation component, the greatest limitations were in d770 Intimate relationships (79.3%) and d240 Handling stress and other psychological demands (82.5%). In the Environmental factors, the most frequent problems were in e110 Products or substances for personal consumption (25%) and e460 Societal attitudes (22.5%); when scored as facilitators, the highest rated categories were e125 Products and technology for communication (100%) and e165 Assets (100%). These results may guide the design of specific treatments for these individuals and serve as a starting point for further studies in similar contexts and in other regions in Russia.

Application of Interpersonal and Social Rhythm Therapy (IPSRT) for Depression Associated With Schizophrenia Spectrum Disorders

People with schizophrenia spectrum disorders frequently experience depression, yet depressive symptoms are often unaddressed. The authors propose that interpersonal and social rhythm therapy (IPSRT) may be effective for individuals with these disorders who experience depression. IPSRT is a manualized, evidence-based treatment for bipolar disorders. It combines the core elements of interpersonal psychotherapy for unipolar depression with social rhythm therapy to target disrupted social rhythms. The authors highlight evidence for the potential utility of IPSRT to treat patients with schizophrenia spectrum disorders and present a case example. IPSRT is one promising therapy that could fill a treatment gap for people with schizophrenia spectrum disorders by addressing depressive symptoms. Future work should build on this rationale and case example to design and implement a randomized controlled trial of IPSRT for treatment of schizophrenia spectrum disorders and evaluate needed modifications.

Functioning and Happiness in People with Schizophrenia: Analyzing the Role of Cognitive Impairment

Schizophrenia is associated with marked functional impairment and low levels of subjective happiness. The aim of the current study was to evaluate the relationship between subjective happiness and functioning in patients with schizophrenia, while considering the role of cognitive functioning. Methods: In total, 69 schizophrenia patients and 87 matched healthy controls participated in the study. Patients’ clinical status was assessed, and a series of self-report questionnaires were administered to both patients and healthy controls to measure subjective happiness, satisfaction with life, well-being, functioning, and cognitive impairment. A multiple linear regression model identified significant predictors of subjective happiness and related constructs. Results: Schizophrenia participants endorsed lower levels of happiness and well-being, and higher perceived stress compared to healthy controls. In schizophrenia patients, there was an inverse and significant correlation (r = −0.435; p = 0.013) between subjective happiness and functioning in a subgroup of patients without cognitive impairment. This correlation was not significant (r = −0.175; p = 0.300) in the subgroup with cognitive impairment. When controlling for other clinical variables (by multiple lineal regression), the severity of symptoms and level of insight failed to demonstrate significant relationships with happiness; meanwhile, perceived stress and some specific cognitive dominions (as verbal learning and processing speed) were associated with satisfaction of life of the patients. Conclusions: The relationship between subjective happiness and functioning in schizophrenia patients was influenced by level of cognitive impairment. Findings from this study suggest that rehabilitation programs may improve recovery outcomes with a focus on subjective happiness and functioning, especially in patients with cognitive impairment. Future research is needed to better understand the complex interplay between subjective happiness, functioning, and cognitive impairment in patients with schizophrenia.

Simple Mobile technology health management tool for people with severe mental illness: a randomised controlled feasibility trial

BACKGROUND

Severe mental illness (SMI) is associated with care delivery problems because of the high levels of clinical resources needed to address patient's psychosocial impairment and to support inclusion in society. Current routine appointment systems do not adequately foster recovery care and are not systematically capturing information suggestive of urgent care needs. This study aimed to assess the feasibility, acceptability, and potential clinical benefits of a mobile technology health management tool to enhance community care for people with severe mental illness.

METHODS

This randomised-controlled feasibility pilot study utilised mixed quantitative (measure on subjective quality of life as primary outcome; questionnaires on self-management skills, medication adherence scale as secondary outcomes) and qualitative (thematic analysis) methodologies. The intervention was a simple interactive technology (Short Message Service - SMS) communication system called 'Florence', and had three components: medication and appointment reminders, daily individually defined wellbeing scores and optionally coded request for additional support. Eligible participants (diagnosed with schizophrenia, schizoaffective disorder or bipolar disorder ≥1 year) were randomised (1:1) to either treatment as usual (TAU, N = 29) or TAU and the technology-assisted intervention (N = 36).

RESULTS

Preliminary results suggest that the health technology tool appeared to offer a practicable and acceptable intervention for patients with SMI in managing their condition. Recruitment and retention data indicated feasibility, the qualitative analysis identified suggestions for further improvement of the intervention. Patients engaged well and benefited from SMS reminders and from monitoring their individual wellbeing scores; recommendations were made to further personalise the intervention. The care coordinators did not utilise aspects of the intervention per protocol due to a variety of organisational barriers. Quantitative analysis of outcomes (including a patient-reported outcome measure on subjective quality of life, self-efficacy/competence and medication adherence measures) did not identify significant changes between groups over time in favour of the Florence intervention, given high baseline scores. The wellbeing scores, however, were positively correlated with all outcome measures.

CONCLUSION

It is feasible to conduct an adequately powered full trial to evaluate this intervention. Inclusion criteria should be revised to include patients with a higher level of need and clinicians should receive more in-depth assistance in managing the tools effectively. The preliminary data suggests that this intervention can aid recovery care and individually defined wellbeing scores are highly predictive of a range of recovery outcomes; they could, therefore, guide the allocation of routine care resources.

In schizophrenia, non-remitters and partial remitters to treatment with antipsychotics are qualitatively distinct classes with respect to neurocognitive deficits and neuro-immune biomarkers: results of soft independent modeling of class analogy

Around one third of schizophrenia patients are non-responders to antipsychotic therapy. The present study aimed to delineate the pathway-phenotypes of non-remitters (NRTT) and partial remitters (PRTT) to treatment with antipsychotics as defined using the Global Clinical Impression scales. We recruited 60 NRTT, 50 PRTT and 43 healthy controls and measured schizophrenia symptoms, neurocognitive tests, plasma CCL11, interleukin-(IL)-6, IL-10, Dickkopf protein 1 (DKK1), high mobility group box-1 protein (HMGB1), κ- and μ-opioid receptors (KOR and MOR, respectively), endomorphin-2 (EM-2), and β-endorphin. Soft independent modeling of class analogy (SIMCA) showed that NRTT and PRTT are significantly discriminated with a cross-validated accuracy of 94.7% and are qualitatively distinct classes using symptomatome, and neuro-immune-opioid-cognitome (NIOC) features as modeling variables. Moreover, a NIOC pathway phenotype discriminated PRTT from healthy controls with an accuracy of 100% indicating that PRTT and controls are two qualitative distinct classes. Using NIOC features as discriminatory variables in SIMCA showed that all PRTT were rejected as belonging to the normal control class and authenticated as belonging to their target class. In conclusion, a non-response to treatment can best be profiled using a SIMCA model constructed using symptomatome and NIOC features. A partial response should be delineated using SIMCA by authenticating patients as controls or PRTT instead of using scale-derived cut-off values or a number of scale items being rated mild or better. The results show that PRTT is characterized by an active NIOC pathway phenotype and that both NRTT and PRTT should be treated by targeting neuro-immune and opioid pathways.

Accelerated transcranial magnetic stimulation (aTMS) to treat depression with treatment switching: study protocol of a pilot, randomized, delayed-start trial

Background

Repetitive transcranial magnetic stimulation (rTMS) is a technique for stimulating brain activity using a transient magnetic field to induce an electrical current in the brain producing depolarization of focal groups of brain cells. TMS is a protocol approved by the U.S. Food and Drug Administration in routine clinical practice as a treatment for depression. A major limitation of rTMS is the large amount of time taken for a standard protocol (38 min a day for 20–30 working days). The optimal type and duration of TMS are still uncertain, as is the optimal strategy for continuing or changing the type of rTMS if there is a poor initial response.

Objectives

The trial aims to assess whether a 1-week compressed course of left dorsolateral prefrontal (L DLPFC) 5 Hz accelerated rTMS (aTMS) treatment is as effective as an established 4-week course of non-accelerated rTMS and if additional 5 Hz L DLPFC aTMS treatments will be efficacious in non-responders as compared to 1 Hz right DLPFC aTMS treatment.

Methods

A randomized, single-blind, delayed-start trial was planned to commence in Jan 2020. A total of 60 patients will be enrolled from the Institute of Mental Health Singapore within a 2-year period and randomized into the early or delayed-start phase of the trial. The primary outcome of the trial is the improvement of Montgomery-Asberg Depression Rating scale at the end of the active treatment phase.

Discussion

If this study protocol proves to be effective, the findings of this trial will be updated to the College of Psychiatrists, Academy of Medicine Singapore, as well as published in a peer-reviewed journal to enhance local and international TMS treatment guidelines.

The interplay between functioning problems and symptoms in first episode of psychosis: An approach from network analysis

The relationship between psychotic symptoms and global measures of functioning has been widely studied. No previous study has assessed so far the interplay between specific clinical symptoms and particular areas of functioning in first-episode psychosis (FEP) using network analysis methods. A total of 191 patients with FEP (age 24.45 ± 6.28 years, 64.9% male) participating in an observational and longitudinal study (AGES-CM) comprised the study sample. Functioning problems were assessed with the WHO Disability Assessment Schedule (WHODAS), whereas the Positive and Negative Syndrome Scale (PANSS) was used to assess symptom severity. Network analysis were conducted with the aim of analysing the patterns of relationships between the different dimensions of functioning and PANSS symptoms and factors at baseline. According to our results, the most important nodes were "conceptual disorganization", "emotional withdrawal", "lack of spontaneity and flow of conversation", "delusions", "unusual thought content", "dealing with strangers" and "poor rapport". Our findings suggest that these symptoms and functioning dimensions should be prioritized in the clinical assessment and management of patients with FEP. These areas may also become targets of future early intervention strategies, so as to improve quality of life in this population.

A network analysis approach to functioning problems in first psychotic episodes and their relationship with duration of untreated illness: Findings from the PAFIP cohort

BACKGROUND

The domains of functioning affected by first episode of psychosis (FEP) could be analysed as forming a network of interacting or even reinforcing elements. The reasons why longer duration of untreated psychosis (DUP) might be related to higher disability are not still clear. The aim of the present study is to evaluate how different areas of functioning are inter-related according to the length of DUP in patients with FEP, with a particular focus on studying the relative influence of each other according to lengthy delays in initial treatment.

METHOD

441 participants in an epidemiological and intervention program of first episode psychosis (PAFIP) were included in our study. Functioning problems at baseline were assessed with the WHO Disability Assessment Schedule (DAS). Three networks of functioning domains have been estimated according to the length of DUP.

RESULTS

All the DAS items took part in the different networks. We have not found differences across the edge weights in the short, medium and long DUP groups. The domains "social withdrawal", "participation in the household activities", "general interest and information", and "low level of activity" seem to act as bridge items with other areas of functioning in people with longer DUP.

CONCLUSIONS

Our results could have clinical implications for patients with longer DUP, in which case, social withdrawal, household activities, level of activity and general interest in the world around them, could be high-priority target areas of treatment, since they seem to be mediating the relation between others areas of functioning.

How does neighbourhood socio-economic status affect the interrelationships between functioning dimensions in first episode of psychosis? A network analysis approach

The links between psychosis and socio-economic disadvantage have been widely studied. No previous study has analysed the interrelationships and mutual influences between functioning dimensions in first episode of psychosis (FEP) according to their neighbourhood household income, using a multidimensional and transdiagnostic perspective. 170 patients and 129 controls, participants in an observational study (AGES-CM), comprised the study sample. The WHO Disability Assessment Schedule (WHODAS 2.0) was used to assess functioning, whereas participants' postcodes were used to obtain the average household income for each neighbourhood, collected by the Spanish National Statistics Institute (INE). Network analyses were conducted with the aim of defining the interrelationships between the different dimensions of functioning according to the neighbourhood household income. Our results show that lower neighbourhood socioeconomic level is associated with lower functioning in patients with FEP. Moreover, our findings suggest that "household responsibilities" plays a central role in the disability of patients who live in low-income neighbourhoods, whereas "dealing with strangers" is the most important node in the network of patients who live in high-income neighbourhoods. These results could help to personalize treatments, by allowing the identification of potential functioning areas to be prioritized in the treatment of FEP according to the patient's neighbourhood characteristics.

Clinical validity of the 12-item WHODAS-2.0 in a naturalistic sample of outpatients with psychotic disorders

BACKGROUND

The World Health Organization Disability Assessment Schedule 2.0 (WHODAS-2.0) is a self-administered instrument to assess functional impairment. It is used in the general population as well as different patient groups. However, its application to patients with psychotic disorders may be hampered by disease-specific difficulties of self-estimation. This study aimed to examine the psychometric properties of the short (12-item) WHODAS-2.0 in a naturalistic sample of outpatients attending a psychosis clinic in Gothenburg, Sweden.

METHODS

Annual data from two outpatient clinics registered 2016-2019 were analyzed retrospectively. The assessment of the short WHODAS-2.0 was based on the first questionnaire completed by 881 patients. Confirmatory factor analysis evaluated previously validated models. Item convergent and discriminant validity as well as internal reliability were computed. Construct validity was assessed by comparing mean differences in accord with previous research regarding patients' characteristics associated with functioning such as advanced age, diagnosed comorbidities, antipsychotic treatment status, and symptom severity measured with PANSS-8 remission items.

RESULTS

A heterogeneous sample was obtained in terms of age (range: 20-92), various living situations, and different geographic areas of birth. Most patients (75%) had been diagnosed with psychotic disorders more than 10 years ago and the majority (89%) were on antipsychotic medication. We confirmed an adjusted two-level factor model with a single second-order disability factor and six first-order factors representing the six IFC dimensions. The WHODAS-2.0 sum score measuring general disability showed good reliability (Cronbach's alpha = 0.89). Construct validity was confirmed as older patients, patients with comorbidities, and patients in assisted living had higher WHODAS-2.0 scores. Patients with no or mild psychotic symptoms had significantly lower WHODAS-2.0 sum scores than patients with more severe symptoms.

CONCLUSIONS

The findings further validate the 12-item WHODAS-2.0 in a naturalistic sample of outpatients with psychotic disorders. This study corroborates the clinical significance of the short, 12-item WHODAS-2.0 by demonstrating consistent associations between patients' age, medical comorbidities, living situation, antipsychotic treatment status, and psychotic symptom severity.

Clinical risk factors, phenomenology and the impact of clozapine induced obsessive compulsive symptoms

The aim of this study was to investigate the clinical risk factors, phenomenology and the impact of clozapine induced obsessive-compulsive symptoms (OCS) in patients with schizophrenia. One hundred twenty-two patients receiving clozapine treatment for at least 6 weeks were assessed with Structured Clinical Interview for Axis-I Disorders for DSM-IV, Positive and Negative Syndrome Scale, Yale-Brown Obsessive Compulsive Scale and Checklist, Calgary Depression Scale, Clinical Global Impression Scale and WHO-Disability Assessment Schedule-II. Information about past and current clinical status were gathered through clinical interviews and medical records. With clozapine 44.3% of the patients had de novo OCS, 33.6% had OCS both before and after clozapine, 21.3% didn't report any OCS. Clozapine doses, clozapine and norclozapine plasma levels were not significantly different. Severity of OCS was affected by clozapine and norclozapine plasma levels, and correlated with increased disability. Obsessions were less in clozapine induced OCS group, and compulsions, especially of checking subtypes, were predominant, compared to the group with prior history of OCS, who reported a significant increase in checking compulsion after clozapine treatment. Clozapine induced OCS should be considered during cost/benefit assessment of clozapine treatment, and understanding the risk factors and its different phenomenology may shed light into the underlying mechanisms.

Naturalistic follow-up study of rehospitalization rates and assigned disability status of patients with first-episode schizophrenia spectrum psychosis in South East Latvia: preliminary results

BACKGROUND

Patients with first-episode schizophrenia spectrum psychosis (FEP) are at risk of not visiting an out-patient psychiatrist and are assigned disability status within a short period after diagnosis.

OBJECTIVE

The aim of this study was to conduct a naturalistic follow-up of FEP patients to explore their use of mental healthcare services and the rate of assigned disability status after FEP.

METHODS

This was the first study in Latvia to include all consecutive patients with FEP admitted to the largest regional hospital in South East Latvia, Daugavpils Psychoneurological Hospital (DPNH). Patients received standard treatment in a real-world environment. The mean follow-up time was 33 months (Min = 20 months, Max = 40 months).

RESULTS

From the 94 consecutive FEP patients admitted to DPNH (1 January 2016 to 31 December 2017), 68 participated and provided informed consent to be followed up. During the first 12 months after discharge from the acute psychiatric ward, 23% (n = 14) never visited a psychiatrist, and 6.5% (n = 4) had a single visit to get prescription for medication. Furthermore, 36.1% (n = 22) had a rehospitalization during the first 12 months. At the end of follow-up period, 34.4% (n = 21) of patients were assigned disability status within a median time of 8 months (IQR 4.5‒20.0).

CONCLUSION

Approximately, one-third of patients did not continue treatment as out-patients after FEP. One-third of FEP patients were assigned disability status. We suggest that Latvia needs improved treatment options for FEP patients, such as early intervention.

Psychiatric rehabilitation through teaching smartphone skills to improve functional outcomes in serious mental illness

This study measured the impact of a digital competencies and skills course on participants with serious mental illness. Close to 75% of participants reported an improvement in a smartphone related skill, and the majority of participants that reported improvement in one skill reported improvement in at least one other. Qualitative feedback from participants suggests how digital competencies acquired were used to immediately support functional outcomes.

OBJECTIVE

To improve functional outcomes in patients with serious mental illness through a multi-session curriculum designed to improve smartphone skills and engage participants in group learning and problem solving, targeting negative and cognitive symptoms of illness.

METHODS

An eight-week smartphone digital competencies and skills course was offered to two distinct groups of youth with serious mental illness. Pre and post self-report measurements were captured for each participant for each session.

RESULTS

Group participation varied by session, but overall 28 unique patients attended. From survey results, 75% reported improvement in smartphone related skills because of the groups. Qualitative feedback suggests how skills acquired by patients were immediately utilized to gain insight into health and support functional outcomes.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Smartphone skills groups are a means to provide practical psychiatric rehabilitation that may enable some patients to compensate for cognitive and social deficits due to illness. While ensuring groups are responsive to patients with varying degrees of skills remains a challenge, adapting lesson structures and mediums, as well as creating new measurement tools, offers a means to modify the course with the clinical need.

Chronic fatigue syndrome and fibromyalgia-like symptoms are an integral component of the phenome of schizophrenia: neuro-immune and opioid system correlates

Physiosomatic symptoms are an important part of schizophrenia phenomenology. The aim of this study is to examine the biomarker, neurocognitive and symptomatic correlates of physiosomatic symptoms in schizophrenia. We recruited 115 schizophrenia patients and 43 healthy controls and measured the Fibromyalgia and Chronic Fatigue Syndrome Rating (FF) scale, schizophrenia symptom dimensions, and the Brief Assessment of Cognition in Schizophrenia. We measured neuro-immune markers including plasma CCL11 (eotaxin), interleukin-(IL)-6, IL-10, Dickkopf protein 1 (DKK1), high mobility group box 1 protein (HMGB1) and endogenous opioid system (EOS) markers including κ-opioid receptor (KOR), μ-opioid receptor (MOR), endomorphin-2 (EM2) and β-endorphin. Patients with an increased FF score display increased ratings of psychosis, hostility, excitement, formal though disorders, psycho-motor retardation and negative symptoms as compared with patients with lower FF scores. A large part of the variance in the FF score (55.1%) is explained by the regression on digit sequencing task, token motor task, list learning, IL-10, age (all inversely) and IL-6 (positively). Neural network analysis shows that the top-6 predictors of the FF score are (in descending order): IL-6, HMGB1, education, MOR, KOR and IL-10. We found that 45.1% of the variance in a latent vector extracted from cognitive test scores, schizophrenia symptoms and the FF score was explained by HMGB1, MOR, EM2, DKK1, and CCL11. Physiosomatic symptoms are an integral part of the phenome of schizophrenia. Neurotoxic immune pathways and lowered immune regulation coupled with alterations in the EOS appear to drive the physiosomatic symptoms of schizophrenia.

Implementing an Action Over Inertia Group Program in Community Residential Rehabilitation Services: Group Participant and Facilitator Perspectives

Introduction: A time-use focused intervention, Action Over Inertia (AOI) designed to address restricted activity patterns and support recovery, was adapted for use in Australian community residential mental health services. Method: Qualitative case study research explored the use of AOI groups across three Community Care Units from the perspectives of group participants with enduring mental illness and group facilitators. Fifteen interviews were conducted: five group participants were interviewed twice 4 weeks apart, and five group facilitators on completion of the group intervention. Interview data were analyzed thematically using constant comparative methods. Findings: Two overarching themes, "Making Change" and "Facilitating Change" were identified. Efforts to make change in their lives were supported by participants recognising the value of personally meaningful activities for well-being and of activity experiences that fostered hope and recovery, whereas a sense of "stuckness," time for activities and life events could disrupt "getting me going." For the facilitators, facilitating change involved recognizing inertia as a challenge; getting people going; and looking at how AOI intervention works to impact inertia. Conclusion: AOI in a group format supports participants to identify barriers to more active living; to appreciate how time-use and well-being interrelate; and to reframe and take steps to overcome inertia. Further research should evaluate AOI groups as a means of providing individualized support for activity re-engagement as part of recovery oriented mental health rehabilitation.

Rating Opportunity for Long-Acting Injectable Antipsychotic Initiation Index (ROLIN)

Background: Schizophrenia is a severe psychiatric condition with devastating consequences for the individual's functionality and leading to severe disability. Lack of insight and non-adherence to treatment remain the most important factors in the progression of the disease to chronicity. Despite their proven effectiveness in preventing relapses, reducing morbidity and mortality, long-acting injectable antipsychotics (LAIs) are still underused. One of the causes invoked is the lack of guidelines or protocols for initiating LAIs. Objective: The aim of this article is to present Rating Opportunity for Long-Acting Injectable Antipsychotic Initiation Index (ROLIN), a clinician-rated index that rates the important factors of the disorder across seven items: age, duration of illness, relapses, antipsychotic treatment response, family support, antipsychotic existing formulation and adherence. Method: A retrospective study in which all patients with schizophrenia discharged on oral antipsychotics without LAIs treatment lifetime were evaluated with ROLIN for opportunity for LAIs initiation. Results: Of 225 consecutive patients, 126 patients (56%) had a strong indication for initiating LAI (score between 25 and 35). Kolmogorov-Smirnov test was used for checking the normal distribution of values (95% CI for the mean = 9.5781 to 20.4219; 95% CI for the median = 6.5920 to 24.8161; SD = 9.7907; Coefficient of Skewness = 0.0743; Coefficient of Kurtosis = -1.1377). Conclusion: This paper proposed an instrument designed to improve treatment in schizophrenia using a simple conceptual model which integrates important predictors of good or poor outcomes.

Mapping Assessments Instruments for Headache Disorders against the ICF Biopsychosocial Model of Health and Disability

Headache disorders have a strong impact on sufferers’ lives. However, the “content” of assessment instruments addressing concepts, such as disability and quality of life (QoL), has not comprehensively been addressed. We searched SCOPUS for research papers in which outcome measures were used in adult populations of patients with migraine, tension-type headache (TTH), and cluster headache (CH). The content of single instruments was then mapped against the International Classification of Functioning, Disability, and Health. A total of 150 papers and 26 instruments were included: 15 addressed disability or impact, two addressed work-related difficulties, and nine addressed QoL. Few instruments were commonly used across the conditions and covered domains of functioning were impact on daily life activities, homework, school, and work-related tasks, leisure time, informal and family relations, pain, emotional difficulties, energy level, and impulse control. Most of the research is based on instruments that were developed for migraine, which is critical for CH, and the impact of headache disorders on work-related activities is poorly acknowledged. Further research is needed to expand the scope of headaches impact on daily life activities, and on environmental factors relevant to headache disorders to raise knowledge on the less represented areas, e.g., TTH impact.

Relationship between disability self-awareness and cognitive and daily living function in schizophrenia

We investigated the relationship between disability self-awareness and cognitive and daily living functions in 49 patients with schizophrenia. The World Health Organization Disability Assessment Schedule 2.0 (WHODAS) self-report was used to identify patient-rated global function. A clinician-rated measure of global function was obtained using the Personal and Social Performance Scale (PSP); disability self-awareness was calculated using two global function scores. The Positive and Negative Syndrome Scale (PANSS) and the Calgary Depression Scale for Schizophrenia (CDSS) were used to evaluate clinical symptoms, while the MATRICS consensus cognitive battery (MCCB) and the UCSD Performance-based Skills Assessment (UPSA) were applied to assess cognitive and daily living functionality, respectively. The WHODAS scores correlated significantly with the MCCB verbal learning, visual learning, and social cognition domains, and with the UPSA communication domain. The PSP correlated significantly with all MCCB and UPSA domains. Disability self-awareness demonstrated positive correlation with most domains of MCCB and UPSA. The findings of this study indicate that the lower the cognitive and daily living function in patients with schizophrenia, the more positively they perceive their own disability.

•

Patients with schizophrenia may have diverse functional disabilities.

•

Function assessment comprises clinician evaluation and patient self-reports.

•

Disability self-awareness was determined using self-report and clinician evaluation.

•

Its relation with cognitive and daily living functions was evaluated in this study.

•

These functions were found to be directly proportional to disability self-awareness.

Meaningful Activities and Recovery (MA&R): the effect of a novel rehabilitation intervention among persons with psychiatric disabilities on activity engagement-study protocol for a randomized controlled trial

Background

Engagement in activities meaningful to the individual may support the process of recovery in those with mental illness. Persons with psychiatric disabilities may reduce their engagement in meaningful activities to various degrees with possible fluctuations over time. We hypothesized that activity engagement can be altered when opportunities and support are offered at an individual and a group peer-based level. Evidence is lacking regarding mental health interventions that enable engagement in meaningful activities, and powered effect studies are warranted.

Methods

We propose an 8-month combined individual and group peer-based intervention, Meaningful Activities and Recovery (MA&R), and a study protocol for a multicentre two-armed parallel randomized controlled trial (RCT). The trial investigates the effects of MA&R in community mental health centres in Copenhagen and municipality services in Denmark. The trial will comprise 128 participants with psychiatric disabilities who will be randomized to one of two groups: (1) MA&R in addition to standard mental healthcare or (2) standard mental healthcare alone. The primary outcome is self-reported activity engagement, measured by Profiles of Engagement in People with Severe Mental Illness. Secondary outcomes are recovery, functioning and quality of life. Data will be collected at baseline and at follow-up at the end of the intervention.

Discussion

This study adds new knowledge to a field with limited evidence, i.e. the clinical effectiveness of rehabilitation interventions among people with psychiatric disabilities, directly targeting activity engagement. The pragmatic design, regarding in- and exclusion criteria and settings, may allow assessment of the intervention’s effect under real-life conditions. The randomization, adequate power and fidelity monitoring allow testing of the intervention’s efficacy. The multicentre study design increases the potential for implementation in various mental health settings if the findings are positive. As the nature of the intervention does not permit blinding of the participants or staff, it may increase the risk of expectancy and performance bias. This must be considered when interpreting the findings.

Genes regulated by BCL11B during T-cell development are enriched for de novo mutations found in schizophrenia patients

While abnormal neurodevelopment contributes to schizophrenia (SCZ) risk, there is also evidence to support a role for immune dysfunction in SCZ. BCL11B, associated with SCZ in genome-wide association study (GWAS), is a transcription factor that regulates the differentiation and development of cells in the central nervous and immune systems. Here, we use functional genomics data from studies of BCL11B to investigate the contribution of neuronal and immune processes to SCZ pathophysiology. We identified the gene targets of BCL11B in brain striatal cells (n = 223 genes), double negative 4 (DN4) developing T cells (n = 114 genes) and double positive (DP) developing T cells (n = 518 genes) using an integrated analysis of RNA-seq and ChIP-seq data. No gene-set was enriched for genes containing common variants associated with SCZ but the DP gene-set was enriched for genes containing missense de novo mutations (DNMs; p = .001) using data from 3,447 SCZ trios. Post hoc analysis revealed the enrichment to be stronger for DP genes negatively regulated by BCL11B. Biological processes enriched for genes negatively regulated by BCL11B in DP gene-set included immune system development and cytokine signaling. These analyses, leveraging a GWAS-identified SCZ risk gene and data on gene expression and transcription factor binding, indicate that DNMs in immune pathways contribute to SCZ risk.

Analysis of global gene expression at seven brain regions of patients with schizophrenia

Previous transcriptome analyses of brain samples provided several insights into the pathophysiology of schizophrenia. In this study, we aimed to re-investigate gene expression datasets from seven brain regions of patients with schizophrenia and healthy controls by adopting a unified approach. After adjustment for confounding factors, we detected gene expression changes in 2 out of 7 brain regions - the dorsolateral prefrontal cortex (DLPFC) and parietal cortex (PC). We found relatively small effect sizes, not exceeding absolute log fold changes of 1. Gene-set enrichment analysis revealed the following alterations: 1) down-regulation of GABAergic signaling (in DLPFC and PC); 2) up-regulation of interleukin-23 signaling together with up-regulation of transcription mediated by RUNX1 and RUNX3 as well as down-regulation of RUNX2 signaling (in DLPFC) and 3) up-regulation of genes associated with responses to metal ions and RUNX1 signaling (PC). The number of neurons was significantly lower and the number of astrocytes was significantly higher at both brain regions. In turn, the index of microglia was increased in DLPFC and decreased in PC. Finally, our unsupervised analysis demonstrated that cellular composition of the samples was a major confounding factor in the analysis of gene expression across all datasets. In conclusion, our analysis provides further evidence that small but significant changes in the expression of genes related to GABAergic signaling, brain development, neuroinflammation and responses to metal ions might be involved in the pathophysiology of schizophrenia. Cell sorting techniques need to be used by future studies to dissect the effect of cellular content.
