The relationship between the duration of untreated psychosis and outcome in low-and-middle income countries: a systematic review and meta analysis

Correlates of adverse childhood experiences among admitted patients with schizophrenia in a referral psychiatric hospital in Botswana

INTRODUCTION

Schizophrenia is becoming more prevalent globally, particularly in lower and middle-income countries. Adverse childhood experiences (ACEs) are significant risk factors for developing and worsening the disorder. This study aimed to determine the pattern and correlates of ACE among inpatients with Schizophrenia at Sbrana Psychiatric Hospital in Botswana.

METHODS

In a cross-sectional cohort study, 128 adult patients diagnosed with Schizophrenia were sampled over a 6-month period. The Adverse Childhood Experiences International Questionnaire (ACE-IQ) and the Positive and Negative Syndrome Scale (PANSS) were used to study ACEs and assess schizophrenia severity. A regression model was used to determine factors that predicted the severity and frequency of admissions, with a significance level set at p ⩽ .05.

RESULTS

Participants were mostly males (78.9%), with a mean age of 36.7 (SD = 11.01). About 93.8% reported at least 1 ACE, and 56.3% had ⩾4 ACEs. There was a positive correlation between the number of ACEs and positive symptoms (rs = .24, p < .01) and the general psychopathology score (rs = .18, p < .05). Having an incarcerated household member (AOR = 2.43; 95% CI [1.02, 5.81]) was associated with PANSS >75. Participants who had experienced physical abuse were more likely to have multiple admissions (AOR = 5.88; 95% 95% CI [1.87, 18.51]).

CONCLUSION

Our findings highlight the high prevalence of multiple ACEs among patients with Schizophrenia. More interventions are therefore needed to mitigate the risk of ACEs.

Causal beliefs regarding schizophrenia and help-seeking behaviors among patients with schizophrenia and family caregivers attending psychiatric clinics in Cambodia

Schizophrenia often follows a chronic or recurrent course, placing an immense burden on patients and their families. Mental health services in Cambodia are still highly limited, thus there is a major treatment gap. It is common that people consult traditional healers (Kru Khmer) and monks. In this culture, people who receive psychiatric medical treatment are expected to exhibit higher mental health literacy, but little is known about this factor. In this study, we interviewed 59 patients with schizophrenia and 59 family caregivers attending psychiatric clinics in Cambodia. Through qualitative analysis using a thematic analysis approach, we extracted eight themes of causal beliefs regarding schizophrenia: (1) spiritual beliefs, (2) cultural symptoms, (3) physical problems, (4) heredity, (5) substance abuse, (6) traumatic events, (7) stress in human relationships or in one's social environment, and (8) socioeconomic position. We found that "thinking too much" (kit chroeun) and "worrying too much" (prouy / barom chroeun), cultural idioms of distress, were recognized as causal factors of schizophrenia by both parents and family caregivers. Some participants were aware of the possible causal factors in light of the latest psychiatry findings, such as genetic factors and childhood trauma. Our data show that causal beliefs are not a decisive factor in shortening the duration of untreated psychosis (DUP). In Cambodia, where the treatment for schizophrenia is pluralistic, we suggest that it is crucial to embed the meaning of psychiatric treatment into local meaning worlds for better help-seeking behaviors.

Intervention Programmes for First-Episode Psychosis: A Scoping Review

The aim of this scoping review was to map intervention programmes for first-episode psychosis by identifying their characteristics, participants, and specific contexts of implementation. It seems reasonable to suggest that early intervention may be beneficial in improving recovery outcomes and reducing the duration of untreated psychosis (DUP). Despite the expansion of these programmes, there are still some significant variations and barriers to access that need to be addressed. In line with the Joanna Briggs Institute (JBI) methodology and the Participants, Concept, and Context (PCC) framework, this review encompasses studies focusing on individuals grappling with early-stage psychosis and their caregivers across a range of settings, including hospital and community environments. The review identified 47 studies from 2002 to 2023, which revealed a great deal of diversity in programme characteristics and implementation contexts. This reflects a global perspective. The results showed that there is a great deal of variety in the characteristics of the programmes, with interventions ranging from single-component strategies, such as cognitive-behavioural therapy (CBT) and cognitive remediation therapy (CRT), to multicomponent programmes that integrate a number of different approaches, including psychosocial, pharmacological, and family-focused strategies. The objectives included attempts to improve cognitive functioning; enhance coping skills; reduce caregiver burden; and address symptoms such as anxiety, depression, and hallucinations. It is notable that there was considerable variation in the frequency, duration, and follow-up periods of the interventions, with some lasting just three sessions over one month and others spanning five years and 48 sessions. The majority of the programmes were delivered in community or outpatient settings, although there were also examples of hospital- and home-based interventions. These findings highlight the value of early interventions and provide a useful resource for adapting programmes to different social and cultural contexts. It would be beneficial for future research to explore how these interventions can be tailored to diverse settings.

Early intervention in psychosis programs in Africa, Asia and Latin America; challenges and recommendations

Background

While early intervention in psychosis (EIP) programs have been increasingly implemented across the globe, many initiatives from Africa, Asia and Latin America are not widely known. The aims of the current review are (a) to describe population-based and small-scale, single-site EIP programs in Africa, Asia and Latin America, (b) to examine the variability between programs located in low-and-middle income (LMIC) and high-income countries in similar regions and (c) to outline some of the challenges and provide recommendations to overcome existing obstacles.

Methods

EIP programs in Africa, Asia and Latin America were identified through experts from the different target regions. We performed a systematic search in Medline, Embase, APA PsycInfo, Web of Science and Scopus up to February 6, 2024.

Results

Most EIP programs in these continents are small-scale, single-site programs that serve a limited section of the population. Population-based programs with widespread coverage and programs integrated into primary health care are rare. In Africa, EIP programs are virtually absent. Mainland China is one of the only LMICs that has begun to take steps toward developing a population-based EIP program. High-income Asian countries (e.g. Hong Kong and Singapore) have well-developed, comprehensive programs for individuals with early psychosis, while others with similar economies (e.g. South Korea and Japan) do not. In Latin America, Chile is the only country in the process of providing population-based EIP care.

Conclusions

Financial resources and integration in mental health care, as well as the availability of epidemiological data on psychosis, impact the implementation of EIP programs. Given the major treatment gap of early psychosis in Africa, Latin America and large parts of Asia, publicly funded, locally-led and accessible community-based EIP care provision is urgently needed.

Childhood trauma and treatment resistance in first-episode psychosis: Investigating the role of premorbid adjustment and duration of untreated psychosis

BACKGROUND

Early identification of treatment non-response in first-episode psychosis (FEP) is essential to outcome. Despite indications that exposure to childhood trauma (CT) can have adverse effects on illness severity, its impact on treatment non-response and the interplay with other pre-treatment characteristics is sparsely investigated. We use a lack of clinical recovery as an early indicator of treatment resistance to investigate the relationship between CT and treatment resistance status at one-year follow-up and the potential mediation of this effect by other pre-treatment characteristics.

METHODS

This prospective one-year follow-up study involved 141 participants recruited in their first year of treatment for a schizophrenia-spectrum disorder. We investigated clinical status, childhood trauma (CT), premorbid adjustment (PA), and duration of untreated psychosis (DUP) at baseline and clinical status at one-year follow-up. Ordinal regression analyses were conducted to investigate how PA and DUP affected the relationship between CT and one-year outcome in FEP.

RESULTS

45 % of the FEP sample reported moderate to severe CT, with significantly higher levels of CT in the early treatment resistant group compared to participants with full or partial early recovery. Ordinal regression analysis showed that CT was a significant predictor of being in a more severe outcome group (OR = 4.59). There was a partial mediation effect of PA and a full mediation effect of DUP on the effect of CT on outcome group membership.

DISCUSSION

Our findings indicate that reducing treatment delays may mitigate the adverse effects of CT on clinical outcomes and support the inclusion of broad trauma assessment in FEP services.

Studying the context of psychoses to improve outcomes in Ethiopia (SCOPE): Protocol paper

BACKGROUND

Global evidence on psychosis is dominated by studies conducted in Western, high-income countries. The objectives of the Study of Context Of Psychoses to improve outcomes in Ethiopia (SCOPE) are (1) to generate rigorous evidence of psychosis experience, epidemiology and impacts in Ethiopia that will illuminate aetiological understanding and (2) inform development and testing of interventions for earlier identification and improved first contact care that are scalable, inclusive of difficult-to-reach populations and optimise recovery.

METHODS

The setting is sub-cities of Addis Ababa and rural districts in south-central Ethiopia covering 1.1 million people and including rural, urban and homeless populations. SCOPE comprises (1) formative work to understand care pathways and community resources (resource mapping); examine family context and communication (ethnography); develop valid measures of family communication and personal recovery; and establish platforms for community engagement and involvement of people with lived experience; (2a) a population-based incidence study, (2b) a case-control study and (2c) a cohort study with 12 months follow-up involving 440 people with psychosis (390 rural/Addis Ababa; 50 who are homeless), 390 relatives and 390 controls. We will test hypotheses about incidence rates in rural vs. urban populations and men vs. women; potential aetiological role of khat (a commonly chewed plant with amphetamine-like properties) and traumatic exposures in psychosis; determine profiles of needs at first contact and predictors of outcome; (3) participatory workshops to develop programme theory and inform co-development of interventions, and (4) evaluation of the impact of early identification strategies on engagement with care (interrupted time series study). Findings will inform development of (5) a protocol for (5a) a feasibility cluster randomised controlled trial of interventions for people with recent-onset psychosis in rural settings and (5b) two uncontrolled pilot studies to test acceptability, feasibility of co-developed interventions in urban and homeless populations.

Factors associated with recovery during schizophrenia and related disorders: A review of meta-analysis

BACKGROUND

The spectrum of schizophrenia disorders (SSD) is a severe mental disorder. It is one of the main medical causes of disability that generates high health and social costs.

OBJECTIVE

To analyze the factors associated with clinical recovery (CR) (symptomatic remission-SR and functional recovery-FR) and personal recovery (PR) in people diagnosed with SSD.

METHODS

14 meta-analyses focused on recovery were reviewed following the PRISMA model statements. 95 % of CI was established.

RESULTS

Shorter Duration of Untreated Psychosis (Zr = 0.24, [0.17, 0.30]) and total Duration of Untreated Illness (Zr = 0.34, [0.20, 0.48]) were related to greater SR and general functioning, respectively. Resilience was the variable with the greatest effect on FR (Zr = 0.67, [0.63, 0.71]). Premorbid adjustment (Zr = 0.34, [0.18, 0.49]) and physical intervention (Zr = 0.71, [0.55, 0.86]) had the greatest effect on occupational and social functioning, respectively. Less severe affective symptoms were related to greater PR (Zr = 0.46, [0.42, 0.50]). There are differences between affective SR and the other types of SR (Zr(SR-A - SR-) = 0.13, Qb = 6.51, p = 0.011), (Zr(SR-A - SR+) = 0.20, Qb = 8.52, p = 0.004), (Zr(SR-A - SR) = 0.18, Qb = 19.29, p = 0.0001). In all, resilience was associated with greater recovery (Zr = 0.67, [0.53, 0.80]), with the global effect being greater on PR than on CR (Zr(PR-CR) = 0.07, Qb = 3.45, p = 0.05).

CONCLUSIONS

Resilience was the variable most strongly associated with recovery. Symptomatic or functional improvement obtained less statistical weight.

Early Intervention in Psychosis and Management of First Episode Psychosis in Low- and Lower-Middle-Income Countries: A Systematic Review

BACKGROUND AND HYPOTHESIS

People with first-episode psychosis (FEP) in low- and lower-middle-income countries (LMIC) experience delays in receiving treatment, resulting in poorer outcomes and higher mortality. There is robust evidence for effective and cost-effective early intervention in psychosis (EIP) services for FEP, but the evidence for EIP in LMIC has not been reviewed. We aim to review the evidence on early intervention for the management of FEP in LMIC.

STUDY DESIGN

We searched 4 electronic databases (Medline, Embase, PsycINFO, and CINAHL) to identify studies describing EIP services and interventions to treat FEP in LMIC published from 1980 onward. The bibliography of relevant articles was hand-searched. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed.

STUDY RESULTS

The search strategy produced 5074 records; we included 18 studies with 2294 participants from 6 LMIC countries. Thirteen studies (1553 participants) described different approaches for EIP. Pharmacological intervention studies (n = 4; 433 participants) found a high prevalence of metabolic syndrome among FEP receiving antipsychotics (P ≤ .005). One study found a better quality of life in patients using injectables compared to oral antipsychotics (P = .023). Among the non-pharmacological interventions (n = 3; 308 participants), SMS reminders improved treatment engagement (OR = 1.80, CI = 1.02-3.19). The methodological quality of studies evidence was relatively low.

CONCLUSIONS

The limited evidence showed that EIP can be provided in LMIC with adaptations for cultural factors and limited resources. Adaptations included collaboration with traditional healers, involving nonspecialist healthcare professionals, using mobile technology, considering the optimum use of long-acting antipsychotics, and monitoring antipsychotic side effects.

Use of the Chinese version of the MATRICS Consensus Cognitive Battery to assess cognitive functioning in individuals with high risk for psychosis, first-episode schizophrenia and chronic schizophrenia: a systematic review and meta-analysis

More than one hundred studies have used the mainland Chinese version of the MATRICS Consensus Cognitive Battery (MCCB) to assess cognition in schizophrenia, but the results of these studies, the quality of the reports, and the strength of the evidence provided in the reports have not been systematically assessed. We identified 114 studies from English-language and Chinese-language databases that used the Chinese MCCB to assess cognition in combined samples of 7394 healthy controls (HC), 392 individuals with clinical high risk for psychosis (CHR-P), 4922 with first-episode schizophrenia (FES), 1549 with chronic schizophrenia (CS), and 2925 with schizophrenia of unspecified duration. The mean difference (MD) of the composite MCCB T-score (-13.72) and T-scores of each of the seven cognitive domains assessed by MCCB (-14.27 to -7.92) were significantly lower in individuals with schizophrenia than in controls. Meta-analysis identified significantly greater cognitive impairment in FES and CS than in CHR-P in six of the seven domains and significantly greater impairment in CS than FES in the reasoning and problem-solving domain (i.e., executive functioning). The only significant covariate of overall cognitive functioning in individuals with schizophrenia was a negative association with the severity of psychotic symptoms. These results confirm the construct validity of the mainland Chinese version of MCCB. However, there were significant limitations in the strength of the evidence provided about CHR-P (small pooled sample sizes) and the social cognition domain (inconsistency of results across studies), and the quality of many reports (particularly those published in Chinese) was rated 'poor' due to failure to report sample size calculations, matching procedures or methods of handling missing data. Moreover, almost all studies were cross-sectional studies limited to persons under 60 with at least nine years of education, so longitudinal studies of under-educated, older individuals with schizophrenia are needed.

Psychosis Recovery Orientation in Malawi by Improving Services and Engagement (PROMISE) protocol

Malawi has a population of around 20 million people and is one of the world's most economically deprived nations. Severe mental illness (largely comprising psychoses and severe mood disorders) is managed by a very small number of staff in four tertiary facilities, aided by clinical officers and nurses in general hospitals and clinics. Given these constraints, psychosis is largely undetected and untreated, with a median duration of untreated psychosis (DUP) of around six years. Our aim is to work with people with lived experience (PWLE), caregivers, local communities and health leaders to develop acceptable and sustainable psychosis detection and management systems to increase psychosis awareness, reduce DUP, and to improve the health and lives of people with psychosis in Malawi. We will use the UK Medical Research Council guidance for developing and evaluating complex interventions, including qualitative work to explore diverse perspectives around psychosis detection, management, and outcomes, augmented by co-design with PWLE, and underpinned by a Theory of Change. Planned deliverables include a readily usable management blueprint encompassing education and community supports, with an integrated care pathway that includes Primary Health Centre clinics and District Mental Health Teams. PWLE and caregivers will be closely involved throughout to ensure that the interventions are shaped by the communities concerned. The effect of the interventions will be assessed with a quasi-experimental sequential implementation in three regions, in terms of DUP reduction, symptom remission, functional recovery and PWLE / caregiver impact, with quality of life as the primary outcome. As the study team is focused on long-term impact, we recognise the importance of having embedded, robust evaluation of the programme as a whole. We will therefore evaluate implementation processes and outcomes, and cost-effectiveness, to demonstrate the value of this approach to the Ministry of Health, and to encourage longer-term adoption across Malawi.

An ecological momentary assessment study of age effects on perceptive and non-perceptive clinical high-risk symptoms of psychosis

Among individuals with clinical high risk for psychosis (CHR), perceptive symptoms are more frequent but have less clinical significance in children/adolescents compared to adults. However, findings are based on clinical interviews relying on patient's recall capacity. Ecological momentary assessment (EMA) can be used to explore experiences in real-time in the subject's daily life. The aim of this study was to assess frequency and stability of (perceptive and non-perceptive) CHR symptoms and to explore potential age effects. EMA was used in a sample of an early detection for psychosis service in Bern, Switzerland (N = 66; 11-36 years). CHR symptoms were recorded in random time intervals for seven days: eight assessments per day per subject, minimum time between prompts set at 25 min. CHR symptoms were additionally assessed with semi-structured interviews including the 'Structured Interview for Psychosis-Risk Syndromes' and the 'Schizophrenia Proneness Instruments'. Mixed-effects linear regression analysis on the frequency of CHR symptoms revealed a significant effect of age group, and the interaction CHR symptoms x age group for both perceptive and non-perceptive symptoms. Further, regarding stability of CHR symptoms, there was a significant effect of the interaction CHR symptoms x age group for perceptive symptoms only. Based on EMA, perceptive CHR symptoms were more frequently reported but less stable in children/adolescents compared with adults. Together with previous findings, our finding of higher instability/variability of perceptive symptoms in younger persons might suggest that with advancing age and more stability of CHR symptoms, clinical relevance (reduced psychosocial functioning) may increase.

Experiences of care-seeking by schizophrenia patients with delayed diagnosis and treatment in rural China: A qualitative study

BACKGROUND

Patients with schizophrenia in rural areas of China face severe delays in getting appropriate treatment due to poverty, transportation, and limited availability of mental healthcare services. However, the experiences of care-seeking among patients with delayed diagnosis and treatment in rural areas remain poorly understood, and it remains unclear how these experiences influence patients' medical mistrust or expectations of care. This study aims to fill that void.

METHODS

We applied a qualitative phenomenological method. Patients were recruited through purposive sampling at a psychiatric hospital in Harbin, China. Semi-structured, one-to-one interviews were conducted, guided by an interview outline. Thematic analysis was performed using Colaizzi's seven-step method.

RESULTS

Data saturation was achieved after interviewing 13 participants aged 21 to 53 years. Three themes with eight subthemes were identified: (i) Barriers to seeking care, (ii) Feelings for psychiatric treatment, and (iii) Demand for mental healthcare. Several factors that may impede the timely diagnosis and treatment were identified, including patients, physicians, and institutions. The participants described their feelings of adverse treatment experiences, as well as expectations arising from this process. It predominantly covers awareness of the disease, supportive access to care, and geographic accessibility of services.

CONCLUSION

Patients with delayed diagnosis and treatment in rural areas often have negative experiences and various needs for mental health services in the pursuit of effective treatments. Policymakers and health planners should seriously consider the current challenges in rural mental healthcare to develop comprehensive strategies for improving prehospital delays and medical experience for this group of patients.

Detecting at-risk mental states for psychosis (ARMS) using machine learning ensembles and facial features

AIMS

Our study aimed to develop a machine learning ensemble to distinguish "at-risk mental states for psychosis" (ARMS) subjects from control individuals from the general population based on facial data extracted from video-recordings.

METHODS

58 non-help-seeking medication-naïve ARMS and 70 healthy subjects were screened from a general population sample. At-risk status was assessed with the Structured Interview for Prodromal Syndromes (SIPS), and "Subject's Overview" section was filmed (5-10 min). Several features were extracted, e.g., eye and mouth aspect ratio, Euler angles, coordinates from 51 facial landmarks. This elicited 649 facial features, which were further selected using Gradient Boosting Machines (AdaBoost combined with Random Forests). Data was split in 70/30 for training, and Monte Carlo cross validation was used.

RESULTS

Final model reached 83 % of mean F1-score, and balanced accuracy of 85 %. Mean area under the curve for the receiver operator curve classifier was 93 %. Convergent validity testing showed that two features included in the model were significantly correlated with Avolition (SIPS N2 item) and expression of emotion (SIPS N3 item).

CONCLUSION

Our model capitalized on short video-recordings from individuals recruited from the general population, effectively distinguishing between ARMS and controls. Results are encouraging for large-screening purposes in low-resource settings.

Traditional healers working with primary care and mental health for early intervention in psychosis in young persons: protocol for the feasibility cluster randomised controlled trial

OBJECTIVES

In low/middle-income countries (LMICs), more than half of patients with first-episode psychosis initially seek treatment from traditional and religious healers as their first care. This contributes to an excessively long duration of untreated psychosis (DUP). There is a need for culturally appropriate interventions to involve traditional and spiritual healers to work collaboratively with primary care practitioners and psychiatrists through task-shifting for early detection, referral and treatment of first episode of psychosis.

METHODS

To prevent the consequences of long DUP in adolescents in LMICs, we aim to develop and pilot test a culturally appropriate and context-bespoke intervention. Traditional HEalers working with primary care and mental Health for early interventiOn in Psychosis in young pErsons (THE HOPE) will be developed using ethnographic and qualitative methods with traditional healers and caregivers. We will conduct a randomised controlled cluster feasibility trial with a nested qualitative study to assess study recruitment and acceptability of the intervention. Ninety-three union councils in district Peshawar, Pakistan will be randomised and allocated using a 1:1 ratio to either intervention arm (THE HOPE) or enhanced treatment as usual and stratified by urban/rural setting. Data on feasibility outcomes will be collected at baseline and follow-up. Patients, carers, clinicians and policymakers will be interviewed to ascertain their views about the intervention. The decision to proceed to the phase III trial will be based on prespecified stop-go criteria.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from Keele University Ethical Review Panel (ref: MH210177), Khyber Medical University Ethical Review Board (ref: DIR/KMU-EB/IG/001005) and National Bioethics Committee Pakistan (ref no. 4-87/NBC-840/22/621). The results of THE HOPE feasibility trial will be reported in peer-reviewed journals and academic conferences and disseminated to local stakeholders and policymakers.

Pathways to care in first-episode psychosis in low-resource settings: Implications for policy and practice

OBJECTIVE

Developing countries such as India face a major mental health care gap. Delayed or inadequate care can have a profound impact on treatment outcomes. We compared pathways to care in first episode psychosis (FEP) between North and South India to inform solutions to bridge the treatment gap.

METHODS

Cross-sectional observation study of 'untreated' FEP patients (n = 177) visiting a psychiatry department in two sites in India (AIIMS, New Delhi and SCARF, Chennai). We compared duration of untreated psychosis (DUP), first service encounters, illness attributions and socio-demographic factors between patients from North and South India. Correlates of DUP were explored using logistic regression analysis (DUP ≥ 6 months) and generalised linear models (DUP in weeks).

RESULTS

Patients in North India had experienced longer DUP than patients in South India (β = 17.68, p < 0.05). The most common first encounter in North India was with a faith healer (45.7%), however, this contact was not significantly associated with longer DUP. Visiting a faith healer was the second most common first contact in South India (23.6%) and was significantly associated with longer DUP (Odds Ratio: 6.84; 95% Confidence Interval: 1.77, 26.49). Being in paid employment was significantly associated with shorter DUP across both sites.

CONCLUSIONS

Implementing early intervention strategies in a diverse country like India requires careful attention to local population demographics; one size may not fit all. A collaborative relationship between faith healers and mental health professionals could help with educational initiatives and to provide more accessible care.

Intervention Programs for First-Episode Psychosis: A Scoping Review Protocol

Early intervention programs for first-episode psychosis aim to intervene in the early stages of the disease. They are essential to prevent and delay the progression of the illness to a more advanced stage, but information about their characteristics is not systematized. The scoping review considered all studies of first-episode psychosis intervention programs, regardless of their context (hospital or community), and explored their characteristics. The scoping review was developed according to the Joanna Briggs Institute methodology and PRISMA-ScR guidelines. The PCC mnemonic (population, concept, and context) addressed research questions, the inclusion and exclusion criteria, and the search strategy. The scoping review sought to identify the literature that meets the predefined inclusion criteria. The research was conducted in the following databases: Web of Science Core Collection, MEDLINE, CINAHL Complete and PsycINFO, Scopus, Cochrane Library, and JBI Evidence Synthesis. The search for unpublished studies included OpenGrey (a European repository) and MedNar. It used sources in English, Portuguese, Spanish, and French. It included quantitative, qualitative, and multi-method/mixed methods studies. It also considered gray or unpublished literature. After removing duplicates, two independent reviewers extracted the relevant information after selecting the articles. If there were disagreements, a third reviewer was used. The researchers have developed a tool based on the JBI model that will allow them to extract the relevant information for the review. The results are presented schematically in narratives and tables. This scoping review maps first-episode psychosis intervention programs by identifying their characteristics, participants, and specific implementation contexts and allows researchers to create multicomponent programs tailored to different contexts.

The neurobiology of duration of untreated psychosis: a comprehensive review

Duration of untreated psychosis (DUP) is defined as the time from the onset of psychotic symptoms until the first treatment. Studies have shown that longer DUP is associated with poorer response rates to antipsychotic medications and impaired cognition, yet the neurobiologic correlates of DUP are poorly understood. Moreover, it has been hypothesized that untreated psychosis may be neurotoxic. Here, we conducted a comprehensive review of studies that have examined the neurobiology of DUP. Specifically, we included studies that evaluated DUP using a range of neurobiologic and imaging techniques and identified 83 articles that met inclusion and exclusion criteria. Overall, 27 out of the total 83 studies (32.5%) reported a significant neurobiological correlate with DUP. These results provide evidence against the notion of psychosis as structurally or functionally neurotoxic on a global scale and suggest that specific regions of the brain, such as temporal regions, may be more vulnerable to the effects of DUP. It is also possible that current methodologies lack the resolution needed to more accurately examine the effects of DUP on the brain, such as effects on synaptic density. Newer methodologies, such as MR scanners with stronger magnets, PET imaging with newer ligands capable of measuring subcellular structures (e.g., the PET ligand [11C]UCB-J) may be better able to capture these limited neuropathologic processes. Lastly, to ensure robust and replicable results, future studies of DUP should be adequately powered and specifically designed to test for the effects of DUP on localized brain structure and function with careful attention paid to potential confounds and methodological issues.

Exploring the effectiveness of family-based interventions for psychosis in low- and middle-income countries: a systematic review

PURPOSE

Of the 80% people with psychosis living in low- and middle-income countries (LMICs), up to 90% are left to the care of families. The World Health Organization has recommended the inclusion of families in community-based rehabilitation and while there is evidence of its implementation in LMICs, this has not been reviewed yet. This study aims to describe the key features and implementation strategies of family-based interventions in LMICs, and appraise their effectiveness.

METHODS

Included are people with psychosis in LMICs who receive any form of family-based intervention, compared to their usual or absence of treatment, with patient outcome measures. We searched (August 2021) through Embase, MEDLINE, Global Health, PsycInfo, Social Policy and Practice, and Cumulative Index to Nursing and Allied Health Literature (CINAHL), as well as from grey literature and hand-searched records. Risk of bias was assessed through the Integrated Quality Criteria for Review of Multiple Study Designs (ICROMS) and Consolidated Health Economic Evaluation Reporting Standards (CHEERS), then analyzed narratively.

RESULTS

27 studies were included from the 5254 records. Psychotherapeutic features, systems approach and task-sharing were key intervention elements. Delivery strategies included preliminary research, sustained family engagement, and cultural adaptation. There were positive health impacts across four outcome domains.

CONCLUSION

All studies recommended family-based interventions, with limitations in heterogeneity and 70% of them rated high risk of bias.

Effects of socioeconomic status in cognition of people with schizophrenia: results from a Latin American collaboration network with 1175 subjects

BACKGROUND

Cognition heavily relies on social determinants and genetic background. Latin America comprises approximately 8% of the global population and faces unique challenges, many derived from specific demographic and socioeconomic variables, such as violence and inequality. While such factors have been described to influence mental health outcomes, no large-scale studies with Latin American population have been carried out. Therefore, we aim to describe the cognitive performance of a representative sample of Latin American individuals with schizophrenia and its relationship to clinical factors. Additionally, we aim to investigate how socioeconomic status (SES) relates to cognitive performance in patients and controls.

METHODS

We included 1175 participants from five Latin American countries (Argentina, Brazil, Chile, Colombia, and Mexico): 864 individuals with schizophrenia and 311 unaffected subjects. All participants were part of projects that included cognitive evaluation with MATRICS Consensus Cognitive Battery and clinical assessments.

RESULTS

Patients showed worse cognitive performance than controls across all domains. Age and diagnosis were independent predictors, indicating similar trajectories of cognitive aging for both patients and controls. The SES factors of education, parental education, and income were more related to cognition in patients than in controls. Cognition was also influenced by symptomatology.

CONCLUSIONS

Patients did not show evidence of accelerated cognitive aging; however, they were most impacted by a lower SES suggestive of deprived environment than controls. These findings highlight the vulnerability of cognitive capacity in individuals with psychosis in face of demographic and socioeconomic factors in low- and middle-income countries.

Cross-country variations in the reporting of psychotic symptoms among sub-Saharan African adults: A psychometric evaluation of the Psychosis Screening Questionnaire

BACKGROUND

Self-reporting of psychotic symptoms varies significantly between cultures and ethnic groups. Yet, limited validated screening instruments are available to capture such differences in the African continent.

METHODOLOGY

Among 9,059 individuals participating as controls in a multi-country case-control study of the genetic causes of psychosis, we evaluated the psychometric properties of the Psychosis Screening Questionnaire (PSQ). We applied multi-group confirmatory factor analysis and item response theory to assess item parameters.

RESULTS

The overall positive endorsement of at least one item assessing psychotic symptoms on the PSQ was 9.7%, with variability among countries (Uganda 13.7%, South Africa 11%, Kenya 10.2%, and Ethiopia 2.8%). A unidimensional model demonstrated good fit for the PSQ (root mean square error of approximation = 0.009; comparative fit index = 0.997; and Tucker-Lewis Index = 0.995). Hypomania had the weakest association with single latent factor (standardized factor loading 0.62). Sequential multi-group confirmatory factor analysis demonstrated that PSQ items were measured in equivalent ways across the four countries. PSQ items gave more information at higher levels of psychosis, with hypomania giving the least discriminating information.

LIMITATIONS

Participants were recruited from general medical facilities, so findings may not be generalizable to the general population.

CONCLUSION

The PSQ demonstrated a unidimensional factor structure in these samples. Items were measured equivalently across all study settings, suggesting that differences in prevalence of psychotic symptoms between countries were less likely to represent measurement artifact. The PSQ is more reliable in screening for psychosis in individuals with higher degrees of psychotic experiences-hypomania excluded-and might decrease the false-positive rate from mild nonspecific psychotic experiences.

Clinical high-risk criteria of psychosis in 8–17-year-old community subjects and inpatients not suspected of developing psychosis

BACKGROUND

In children and adolescents compared to adults, clinical high-risk of psychosis (CHR) criteria and symptoms are more prevalent but less psychosis-predictive and less clinically relevant. Based on high rates of non-converters to psychosis, especially in children and adolescents, it was suggested that CHR criteria were: (1) Pluripotential; (2) A transdiagnostic risk factor; and (3) Simply a severity marker of mental disorders rather than specifically psychosis-predictive. If any of these three alternative explanatory models were true, their prevalence should differ between persons with and without mental disorders, and their severity should be associated with functional impairment as a measure of severity.

AIM

To compare the prevalence and severity of CHR criteria/symptoms in children and adolescents of the community and inpatients.

METHODS

In the mainly cross-sectional examinations, 8–17-year-old community subjects (n = 233) randomly chosen from the population register of the Swiss Canton Bern, and inpatients (n = 306) with primary diagnosis of attention-deficit/hyperactivity disorder (n = 86), eating disorder (n = 97), anxiety including obsessive–compulsive disorder (n = 94), or autism spectrum disorder (n = 29), not clinically suspected to develop psychosis, were examined for CHR symptoms/criteria. Positive items of the Structured Interview for Psychosis-Risk Syndromes (SIPS) were used to assess the symptomatic ultra-high-risk criteria, and the Schizophrenia Proneness Instrument, Child and Youth version (SPI-CY) was used to assess the 14 basic symptoms relevant to basic symptom criteria. We examined group differences in frequency and severity of CHR symptoms/criteria using χ² tests and nonparametric tests with Cramer’s V and Rosenthal’s r as effect sizes, and their association with functioning using correlation analyses.

RESULTS

The 7.3% prevalence rate of CHR criteria in community subjects did not differ significantly from the 9.5% rate in inpatients. Frequency and severity of CHR criteria never differed between the community and the four inpatient groups, while the frequency and severity of CHR symptoms differed only minimally. Group differences were found in only four CHR symptoms: suspiciousness/persecutory ideas of the SIPS [χ² (4) = 9.425; P = 0.051, Cramer’s V = 0.132; and Z = -4.281, P < 0.001; Rosenthal’s r = 0.184], and thought pressure [χ² (4) = 11.019; P = 0.026, Cramer’s V = 0.143; and Z = -2.639, P = 0.008; Rosenthal’s r = 0.114], derealization [χ² (4) = 32.380; P < 0.001, Cramer’s V = 0.245; and Z = -3.924, P < 0.001; Rosenthal’s r = 0.169] and visual perception disturbances [χ² (4) = 10.652; P = 0.031, Cramer’s V = 0.141; and Z = -2.822, P = 0.005; Rosenthal’s r = 0.122] of the SPI-CY. These were consistent with a transdiagnostic risk factor or dimension, i.e., displayed higher frequency and severity in inpatients, in particular in those with eating, anxiety/obsessive–compulsive and autism spectrum disorders. Low functioning, however, was at most weakly related to the severity of CHR criteria/symptoms, with the highest correlation yielded for suspiciousness/persecutory ideas (Kendall’s tau = -0.172, P < 0.001).

CONCLUSION

The lack of systematic differences between inpatients and community subjects does not support suggestions that CHR criteria/symptoms are pluripotential or transdiagnostic syndromes, or merely markers of symptom severity.

The effects of childhood adversity on treatment delays and its components in first-episode psychosis

Apart from increasing risk for psychotic disorders, childhood adversity has been associated with worse outcomes. One way in which childhood adversity may worsen outcomes is by lengthening treatment delays, which are associated with negative impacts. We tested the influence of childhood trauma on treatment delays, measured as the duration of untreated psychosis (DUP), and its help-seeking and referral components, in a first-episode psychosis cohort (N = 203). We accounted for pertinent social (e.g., migrant status) and other determinants (i.e., age at onset, diagnosis, symptoms) of treatment delays. Multiple linear regression analyses revealed that for a one-unit increase in Childhood Trauma Questionnaire (CTQ) scores, average overall DUP increased by 25%. Higher CTQ scores also significantly predicted help-seeking and referral DUPs. Patients with schizophrenia-spectrum psychosis had longer help-seeking and total DUPs than those with affective psychosis. More severe positive symptoms predicted longer help-seeking DUPs, while more severe negative symptoms predicted longer referral DUPs. Indicators of social disadvantage did not affect DUP. Our results show that childhood trauma increases DUP by prolonging the help-seeking process and delaying access to mental healthcare even after help is sought. Early identification of psychosis among populations with trauma histories seems warranted and can likely positively impact outcomes.

Multifamily groups for patients with schizophrenia: an exploratory randomised controlled trial in Bosnia and Herzegovina

BACKGROUND

Schizophrenia has a significant and lasting impact on the quality of life of patients and their families and is a leading cause of disability globally. Family interventions can be beneficial and may be particularly appropriate in settings with limited resources. We conducted an exploratory trial testing the effectiveness of a multifamily group intervention, which draws on the traditions of psychoeducation and trialogue, for improving the quality of life of patients with schizophrenia in Bosnia and Herzegovina.

METHODS

We conducted an exploratory, randomised controlled trial with patients with schizophrenia attending an outpatient clinic in Sarajevo. Our primary outcome was improved quality of life at 6-month follow-up. Secondary outcomes included objective social outcomes, psychiatric symptoms and psychiatric hospitalisation measured at 6 and 12 months. Experiences of participants were assessed in post-intervention interviews.

RESULTS

72 patients were randomly assigned to either one of six multifamily groups or treatment as usual. Follow-up assessments were completed with 53 patients (74%) at 6 months and 55 patients (76%) at 12 months. The intervention significantly improved quality of life at 6 months (Cohen's d = 0.78, F = 6.37, p = 0.016) and 12 months (d = 1.08, F = 17.92, p < 0.001), compared with treatment as usual. Re-hospitalisation rates at 6 months and symptom levels also improved significantly whilst changes in other secondary outcomes failed to reach statistical significance.

CONCLUSION

These findings suggest multifamily groups can be effective for improving the quality of life of patients with schizophrenia in Bosnia and Herzegovina. Further research is required to assess how multifamily groups may be scaled up in similar settings with limited resources.

Proportion and predictors of remission and recovery in first-episode psychosis: Systematic review and meta-analysis

Background

To determine the proportion of patients in symptomatic remission and recovery following a first-episode of psychosis (FEP).

Methods

A multistep literature search using the Web of Science database, Cochrane Central Register of Reviews, Ovid/PsychINFO, and trial registries from database inception to November 5, 2020, was performed. Cohort studies and randomized control trials (RCT) investigating the proportion of remission and recovery following a FEP were included. Two independent researchers searched, following PRISMA and MOOSE guidelines and using a PROSPERO protocol. We performed meta-analyses regarding the proportion of remission/recovery (symptomatic plus functional outcomes). Heterogeneity was measured employing Q statistics and I² test. To identify potential predictors, meta-regression analyses were conducted, as well as qualitative reporting of studies included in a systematic review. Sensitivity analyses were performed regarding different times of follow-up and type of studies.

Results

One hundred articles (82 cohorts and 18 RCTs) were included in the meta-analysis. The pooled proportion of symptomatic remission was 54% (95%CI [30, 49–58]) over a mean follow-up period of 43.57 months (SD = 51.82) in 76 studies. After excluding RCT from the sample, the proportion of remission remained similar (55%). The pooled proportion of recovery was 32% (95%CI [27–36]) over a mean follow-up period of 71.85 months (SD = 73.54) in 40 studies. After excluding RCT from the sample, the recovery proportion remained the same. No significant effect of any sociodemographic or clinical predictor was found.

Conclusions

Half of the patients are in symptomatic remission around 4 years after the FEP, while about a third show recovery after 5.5 years.

Pharmacological or non-pharmacological interventions for treatment of common mental disorders associated with Tuberculosis: A systematic review

We aimed to review the literature on interventions for treating Common Mental Disorders (CMD) in people with Tuberculosis (TB). We followed PRISMA guidelines and the protocol was registered at PROSPERO. The electronic databases (PsycInfo, CINAHL, Medline, Google Scholar, Embase) were searched from 1982 to 2020. 349 relevant records were screened, with 26 examined at full text. 13 studies were included totalling 4326 participants. A meta-analysis was not possible due to nature of data, thus descriptive synthesis was conducted. Eleven studies evaluated psychosocial interventions, which significantly improved adherence or cure rates from TB, anxiety and depression. The elements of effective psychosocial interventions included; combating stigma, socioeconomic disadvantage, managing associated guilt and fear of contagion, and explanatory models of illness in local population. Two articles evaluated pharmacological interventions (antidepressants and Vitamin D). This is the first systematic review of interventions to treat CMD in TB. The studies were mostly low quality and mental health outcomes were not adequately described. However, this review suggests that it is feasible to develop and test interventions for improving mental health outcomes and enhancing treatment adherence in TB.

Contemporary psychiatric intervention for chronic schizophrenia patients incarcerated in a religious asylum in Taiwan

BACKGROUND/PURPOSE

In 2017, Long-Fa Temple, an illegal religious asylum in Taiwan, was forced to shut down. Hundreds of chronic mentally ill patients were incarcerated there but provided with no modern psychiatric treatment. This study investigated the effectiveness of providing psychiatric intervention for patients subsequently transferred from Long-Fa Temple to a medical center.

METHODS

In total, 88 patients (mean age: 57.2 years, 52.3% male) who had been incarcerated at Long-Fa Temple were transferred to a southern medical center. The patients underwent comprehensive biological, psychological, and social treatment for 18 months. The patients were evaluated once a month in terms of their psychotic symptoms, self-care, nutrition status, cognitive function, occupational function, and family function.

RESULTS

Regarding the patients' length of stay, 18.2% were incarcerated in Long-Fa Temple for less than 10 years, 21.6% for 10-20 years, and 60.2% for more than 20 years. In terms of psychiatric diagnosis, 98.9% of the patients had been diagnosed with a schizophrenia spectrum disorder. During the 18-month treatment period, negative symptoms decreased significantly, while the patients' self-care ability, nutrition status, cognition, occupational function, and family function all significantly improved over time. Patients who had been incarcerated for less than 10 years demonstrated better improvements in psychotic symptoms, self-care, nutrition status, and cognitive function.

CONCLUSION

Contemporary psychiatric intervention is beneficial for chronically untreated mentally ill patients, and the patients who had a shorter duration of illness had a better reserve of recovery. These findings can serve as an important reference for psychiatric intervention in developing countries.

The clinical significance of duration of untreated psychosis: an umbrella review and random-effects meta-analysis

The idea that a longer duration of untreated psychosis (DUP) leads to poorer outcomes has contributed to extensive changes in mental health ser-vices worldwide and has attracted considerable research interest over the past 30 years. However, the strength of the evidence underlying this notion is unclear. To address this issue, we conducted an umbrella review of available meta-analyses and performed a random-effects meta-analysis of primary studies. MEDLINE, Web of Science, PsycINFO and EMBASE were searched from inception to September 3, 2020 to identify relevant meta-analyses of studies including patients with schizophrenia spectrum disorders, first-episode psychosis, or affective and non-affective psychosis. Thirteen meta-analyses were included, corresponding to 129 individual studies with a total sample size of 25,657 patients. We detected potential violations of statistical assumptions in some of these meta-analyses. We therefore conducted a new random-effects meta-analysis of primary studies. The association between DUP and each outcome was graded according to a standardized classification into convincing, highly suggestive, suggestive, weak, or non-significant. At first presentation, there was suggestive evidence for a relationship between longer DUP and more severe negative symptoms (beta=-0.07, p=3.6×10^-5 ) and higher chance of previous self-harm (odds ratio, OR=1.89, p=1.1×10^-5 ). At follow-up, there was highly suggestive evidence for a relationship between longer DUP and more severe positive symptoms (beta=-0.16, p=4.5×10^-8 ), more severe negative symptoms (beta=-0.11, p=3.5×10^-10 ) and lower chance of remission (OR=2.16, p=3.0×10^-10 ), and suggestive evidence for a relationship between longer DUP and poorer overall functioning (beta=-0.11, p=2.2×10^-6 ) and more severe global psychopathology (beta=-0.16, p=4.7×10^-6 ). Results were unchanged when analysis was restricted to prospective studies. These effect sizes are clinically meaningful, with a DUP of four weeks predicting >20% more severe symptoms at follow-up relative to a DUP of one week. We conclude that DUP is an important prognostic factor at first presentation and predicts clinically relevant outcomes over the course of illness. We discuss conceptual issues in DUP research and methodological limitations of current evidence, and provide recommendations for future research.

A systematic review of care pathways for psychosis in low-and middle-income countries

Pathways to care for psychosis in high-income countries have been well studied, with the finding of an association between longer duration of untreated psychosis (DUP) and poorer outcomes focusing interest on care pathways to minimise treatment delay. Little is known about how people with psychosis in low-to middle-income countries (LMIC) present for help and specific care pathways that might be associated with treatment delays in those contexts. We conducted a systematic review using electronic databases (MEDLINE, PsychINFO, Embase, Ovid) to explore what proportion of patients with psychosis in LMIC are accessing care through traditional healers and whether this is associated with treatment delay. Studies were included if they assessed the pathway to care for participants with a psychotic illness in a LMIC. From 3929 results, 15 studies met our inclusion criteria. In 7 out of 15 studies first contact for the majority of patients were traditional health practitioners (THPs). In 5 out of 15 studies, mental health practitioners (MHPs) were most often the initial care pathway and in 3 studies first contact was with primary care. DUP ranged from a mean of 30 weeks to 225 weeks. Accessing THPs as initial contact was associated with a longer DUP. In LMICs, a large proportion of patients use THP as their first point of contact for accessing care. This is associated with longer DUP. Services in these countries need to focus both on raising public awareness and collaborative working with THPs to facilitate access to biomedical care.

Impact of duration of untreated psychosis in short-term response to treatment and outcome in antipsychotic naïve first-episode psychosis

AIM

Duration of untreated psychosis (DUP) is one of the few potentially modifiable outcome predictors in psychosis. Previous studies have associated a longer DUP with a poor prognosis, but few of them were performed in countries with low and middle level of income. This study aimed to investigate the DUP in a Brazilian sample of antipsychotic-naïve first-episode psychosis (AN-FEP) patients and its association with clinical characteristics and treatment outcomes in a short-term follow-up.

METHODS

One hundred forty-five AN-FEP patients between 16 and 40 years were enrolled and were reassessed 10 weeks after risperidone treatment. We investigated the association between DUP and symptom severity, functionality and response to treatment, using the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression-Severity Scale (CGI) and the Global Assessment of Functionality (GAF) scale. DUP was defined as the period between the onset of the first psychotic symptoms and the first effective antipsychotic treatment. For the analysis, we performed multivariate linear regressions.

RESULTS

The DUP's median was 61 days. At baseline, we did not find any significant association between DUP and clinical characteristics. After treatment, the longer DUP predicted worse positive and negative symptom dimensions, worse total PANSS, GAF and CGI scores and poorer response to treatment.

CONCLUSION

Our results showed that DUP is associated with worse outcomes after short treatment, but it does not modify the baseline clinical profile of the AN-FEP patients. Such results reinforce the need to develop early intervention strategies, reducing DUP.

Very long-term outcome of psychotic disorders

BACKGROUND

The outcome of schizophrenia and related psychoses is generally modest, and patients display high rates of disability.

AIMS

The aim of the review is to present an up-to-date account of the research on the very long-term outcome of psychotic disorders.

METHOD

We conducted a search in the PubMed and Scopus databases for articles published since the publication of the very long-term data of the World Health Organization's International Study of Schizophrenia (the ISoS study), over the last 18 years (from 2002 to 2019). Studies were included if they reported on at least 15-year outcome and if they had used valid and reliable tools for the estimation of the patients' outcome in terms of symptomatology and functioning.

RESULTS

A total of 16 studies were included in this review, involving 1,391 patients with schizophrenia and related psychoses. Most were single-center studies, with moderate size samples of patients, and 11 were prospective studies. Very long-term outcome of psychotic disorders varies considerably among studies. Good outcome ranges from 8% to 73.8%, and it appears to be better in developing countries, whereas differences are less apparent among Western countries (8%-40.3%). Studies in different settings have used different methods involving a variety of samples of patients to estimate their outcome, whereas definitions of good and poor outcome also varied among studies. Longer duration of untreated psychosis was associated with worse outcome in some studies. Schizophrenia was found to have poorer long-term prognosis compared to other schizophrenia spectrum disorders. A large proportion of patients, ranging from 19% to 48.2%, were not on medication.

CONCLUSION

Recent evidence on the very long-term outcome of psychotic disorders is in line with previous reports and suggests that prognosis remains rather modest. There are several limitations of current research regarding outcome definitions and study design that should be addressed by future research.

Association Between the Duration of Untreated Psychosis and Selective Cognitive Performance in Community-Dwelling Individuals With Chronic Untreated Schizophrenia in Rural China

IMPORTANCE

Cognitive deficits constitute core features of schizophrenia, but the trajectories of cognitive difficulties in chronic untreated schizophrenia remain unclear.

OBJECTIVE

To assess the association of neuropsychological deficits with duration of untreated psychosis in individuals with chronic untreated schizophrenia.

DESIGN, SETTING, AND PARTICIPANTS

Community-dwelling individuals with chronic untreated schizophrenia (untreated patient group) and individuals without mental illness (control group) were recruited from predominantly rural communities in Ningxia, China between June 20, 2016, and August 6, 2019, and administered the Structured Clinical Interview for DSM-IV, the Mini-Mental State Examination, an 8-test version of the MATRICS Consensus Cognition Battery adapted for use in individuals with low levels of education, and a measure of social cognition.

MAIN OUTCOMES AND MEASURES

Comparison of cognitive test scores between the two groups and association of cognitive test scores with duration of untreated schizophrenia.

RESULTS

The patient group included 197 individuals with chronic untreated schizophrenia (101 men [51.3%]; mean [SD] age, 52.1 [11.8] years; median [interquartile range] years of schooling, 3 [0-6] years; median [interquartile range] years of untreated psychosis, 22.9 [14.9-32.8] years). The control group included 220 individuals (118 men [53.6%]; mean [SD] age, 52.1 [11.2] years; median [interquartile range] years of schooling, 4 [0-6] years). The untreated patient group performed significantly worse than the control group on all cognitive measures (adjusted partial Spearman correlation coefficient [Spearman ρ] ranged from -0.35 for the revised Chinese version of the Reading the Mind in the Eyes Test to -0.60 for the Brief Visuospatial Memory Test-Revised; P < .001 for all comparisons). Longer durations of untreated psychosis were associated with lower performance in 3 MATRICS Consensus Cognition Battery measures assessing different aspects of executive functioning (Brief Visuospatial Memory Test-Revised [ρ = -0.20; P = .04]; Brief Assessment of Cognition in Schizophrenia, Symbol Coding subtest [ρ = -0.35; P < .001]; and Neuropsychological Assessment Battery, Mazes subtest [ρ = -0.24; P = .01]). The median duration of untreated psychosis (22.9 years) was associated with estimated score reductions in the 3 measures of 34% (95% CI, 10%-52%), 43% (95% CI, 28%-55%), and 57% (95% CI, 31%-73%), respectively.

CONCLUSIONS AND RELEVANCE

The findings of this study suggest that long-term untreated schizophrenia was associated with decreases in selective cognitive abilities; both neurodegenerative pathology and neurodevelopmental dysfunction may be factors in cognition in persistent psychosis. Expanding research to include cohorts of patients from underserved rural communities in low- and middle-income countries may provide new insights about the etiological factors, disease course, and management of schizophrenia.

Time delay in seeking treatment for first-episode schizophrenia: a retrospective study

AIM

A longer duration of untreated psychosis (DUP) is associated with higher risk of relapse and a poorer overall prognosis. The study is designed to explore the duration of untreated schizophrenia and associated factors in Northwest China.

METHODS

A total of 7252 patients with first-episode schizophrenia registered from 1 January 2011 to 31 December 2018 in Yulin of China were included. The median delay time was estimated by Kaplan-Meier survival curve. Two-level mixed-effects survival model was used to calculate the hazard ratio and 95% confidence interval for factors associated with treatment delay. The outcome variable of interest was defined as 'receiving antipsychotic treatment'.

RESULTS

Up to 40.4% of patients with schizophrenia were illiterate and 78% were farmers and 75.6% were living under the national poverty line. The median treatment delay was 30 months (Interquartile range: 2-217). Older age at onset (age group 21-28, HR 1.3; 29-39, HR 1.3; 40 above, HR 1.4), female gender (HR 1.1), unmarried status(HR 1.1) and high educational level (primary, HR 1.4; Junior HR 1.8 and high school and above, HR 1.8) were found to be associated with lower risk of treatment delay. Widowed status (HR 0.6) was associated with an increased risk of treatment delay.

CONCLUSIONS

The median duration of untreated schizophrenia in this study was longer than findings reported in many prior studies. Early age of onset, male patients, widowed status and low education level were at high risk of treatment delay. Early detection, diagnosis and treatment of schizophrenia in northwest China should be strengthened.

Supervised treatment in outpatients for schizophrenia plus (STOPS+): protocol for a cluster randomised trial of a community-based intervention to improve treatment adherence and reduce the treatment gap for schizophrenia in Pakistan

INTRODUCTION

There is a significant treatment gap, with only a few community-based services for people with schizophrenia in low-income and middle-income countries. Poor treatment adherence in schizophrenia is associated with poorer health outcomes, suicide attempts and death. We previously reported the effectiveness of supervised treatment in outpatients for schizophrenia (STOPS) for improving treatment adherence in patients with schizophrenia. However, STOPS was evaluated in a tertiary care setting with no primary care involvement, limiting its generalisability to the wider at-risk population. We aim to evaluate the effectiveness of STOPS+ in scaling up the primary care treatment of schizophrenia to a real-world setting.

METHODS AND ANALYSIS

The effectiveness of the STOPS+ intervention in improving the level of functioning and medication adherence in patients with schizophrenia in Pakistan will be evaluated using a cluster randomised controlled trial design. We aim to recruit 526 participants from 24 primary healthcare centres randomly allocated in 1:1 ratio to STOPS+ intervention and enhanced treatment as usual arms. Participants will be followed-up for 12 months postrecruitment. The sample size is estimated for two outcomes (1) the primary clinical outcome is level of functioning, measured using the Global Assessment of Functioning scale and (2) the primary process outcome is adherence to treatment regimen measured using a validated measure. An intention-to-treat approach will be used for the primary analysis.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from Keele University Ethical Review Panel (ref: MH-190017) and Khyber Medical University Ethical Review Board (ref: DIR-KMU-EB/ST/000648). The results of the STOPS+ trial will be reported in peer-reviewed journals and academic conferences and disseminated to local stakeholders and policymakers.

The interRAI Suite of Mental Health Assessment Instruments: An Integrated System for the Continuum of Care

The lives of persons living with mental illness are affected by psychological, biological, social, economic, and environmental factors over the life course. It is therefore unlikely that simple preventive strategies, clinical treatments, therapeutic interventions, or policy options will succeed as singular solutions for the challenges of mental illness. Persons living with mental illness receive services and supports in multiple settings across the health care continuum that are often fragmented, uncoordinated, and inadequately responsive. Appropriate assessment is an important tool that health systems must deploy to respond to the strengths, preferences, and needs of persons with mental illness. However, standard approaches are often focused on measurement of psychiatric symptoms without taking a broader perspective to address issues like growth, development, and aging; physical health and disability; social relationships; economic resources; housing; substance use; involvement with criminal justice; stigma; and recovery. Using conglomerations of instruments to cover more domains is impractical, inconsistent, and incomplete while posing considerable assessment burden. interRAI mental health instruments were developed by a network of over 100 researchers, clinicians, and policy experts from over 35 nations. This includes assessment systems for adults in inpatient psychiatry, community mental health, emergency departments, mobile crisis teams, and long-term care settings, as well as a screening system for police officers. A similar set of instruments is available for child/youth mental health. The instruments form an integrated mental health information system because they share a common assessment language, conceptual basis, clinical emphasis, data collection approach, data elements, and care planning protocols. The key applications of these instruments include care planning, outcome measurement, quality improvement, and resource allocation. The composition of these instruments and psychometric properties are reviewed, and examples related to homeless are used to illustrate the various applications of these assessment systems.

Effects of socio-demographic characteristics, premorbid functioning, and insight on duration of untreated psychosis in first-episode schizophrenia or schizophreniform disorder in Northern Malawi

AIM

Long duration of untreated psychosis (DUP) is prevalent and has been shown to be associated with poorer prognosis. Thus, knowledge of its determinants may help to target early interventions to reduce DUP on the needed population. Previous studies seeking to understand determinants of DUP have been inconclusive. Therefore, this study aimed to investigate the effects of socio-demographic characteristics, premorbid functioning, and insight on DUP in patients with first-episode schizophrenia or schizophreniform disorder.

METHODS

This cross-sectional study recruited 110 subjects (aged 18-65) during a pilot early intervention service for psychosis in Northern Malawi, between June 2009 and September 2012. Short DUP was defined as ≤6 months, whereas long DUP was defined as >6 months. Unadjusted and adjusted analyses were performed to identify determinants of DUP.

RESULTS

Of the 110 subjects, 99 (90%) had schizophrenia. Median DUP was 27.5 months, while mean (SD) DUP was 71.24 (92.32) months. In addition, at least 75% had long DUP, which was associated with lower level of education, poor insight, younger age at onset, and at least one parent deceased.

CONCLUSIONS

Long DUP is prevalent in Northern Malawi. Thus, early interventions to reduce DUP are warranted in this population. Although having at least one parent deceased predicted long DUP in this study, this remains speculative because factors, such as timing of parents' death and grief reactions of the patients were not assessed. Therefore, further investigations incorporating these factors are needed to ascertain this result.

Duration of Untreated Psychosis Correlates With Brain Connectivity and Morphology in Medication-Naïve Patients With First-Episode Psychosis

BACKGROUND

In the United States, the average duration of untreated psychosis (DUP) is 21 months, and it remains unknown how longer DUP may affect brain functioning in antipsychotic-naïve patients with first-episode psychosis. The objective was to determine the effects of DUP on functional connectivity and brain morphology measured with resting-state functional and structural magnetic resonance imaging.

METHODS

Medication-naïve patients with first-episode psychosis were referred from various clinical settings. After accounting for exclusion criteria, attrition, and data quality, final analyses included 55 patients (35 male and 20 female; mean age, 24.18 years). Patients with first-episode psychosis were subjected to a 16-week trial of risperidone, a commonly used antipsychotic drug. Treatment response was calculated as change in the psychosis subscale of the Brief Psychiatric Rating Scale between baseline and 16 weeks. Resting-state functional connectivity magnetic resonance imaging and brain morphology (surface area and cortical thickness) were assessed.

RESULTS

Longer DUP was associated with worse treatment response and reduced functional connectivity-more specifically in the default, salience, and executive networks. Moreover, longer DUP was associated with reduced surface area in the salience and executive networks and with increased cortical thickness in the default mode and salience networks. When the functional connectivity of the default mode network was added as a mediator, the relationship between DUP and treatment response was no longer significant.

CONCLUSIONS

These data suggest that several neurobiological alterations in the form of reduced functional connectivity and surface area and increased cortical thickness underpin the effect of prolonged DUP.

Early psychosis in Indonesia: reflections on illness and treatment

This paper provides an overview of more than 22 years of research conducted in the central Javanese province of Yogyakarta, Indonesia, by teams of researchers associated with Gadjah Mada University and Harvard University, led by the authors of this essay. This work is placed in the context of the very limited literature on early psychosis and mental health services in Indonesia. It provides an overview of mental health services in Indonesia and of this team's research trajectory, then addresses four key domains: the cultural phenomenology of early experiences of psychotic illness; patterns of onset, with a particular focus on extremely rapid onset psychoses; patterns of care-seeking for first episode illness; and mental health services and patterns of utilization. It then discusses the importance of rapid onset psychosis for research on early psychosis, and the question of whether collinearity of rapidity of onset and rapidity of care-seeking raises questions about the long-standing finding that a short duration of untreated psychosis leads to better outcomes. It concludes by discussing difficulties of prioritizing early intervention models in settings with very low mental health resources.

A cross-sectional mixed methods protocol to describe correlates and explanations for a long duration of untreated psychosis among patients with first episode psychosis in Uganda

INTRODUCTION

Among patients with psychotic disorders, the 'duration of untreated psychosis' (DUP) is a predictor of key outcomes such as symptom remission and quality of life. In sub-Saharan Africa, DUP is up to five times longer than in high-income countries, with many patients going without antipsychotic medication for 5 years or longer. One contributor to this high DUP may relate to cultural norms that drive use of alternative and complementary therapies (ACTs) as first-line treatment strategies, rather than biomedical care with antipsychotic medicine. We aim to1 determine the prevalence and factors associated with DUP and ACT use in Uganda, and2 Identify factors that drive patient and family choices to use ACT as a first-line treatment strategy.

METHODS AND ANALYSIS

We will leverage on an ongoing cohort study at the national psychiatric and teaching hospital in Uganda. The parent study is an observational cohort design following antipsychotic naïve adults with a first episode of psychosis without substance use, HIV/AIDS or syphilis. The embedded study will use a mixed methods design including quantitative assessment of parent study participants with the Nottingham Onset Schedule-DUP to determine the DUP. Qualitative assessment will focus on patient and caregiver perceptions and use of ACT and its impact on DUP among patients with psychosis using in-depth interviews.

ETHICS AND DISSEMINATION

The study has received ethical approval from the school of medicine research and ethics committee of the college of health sciences at Makerere University. It has also received institutional support to perform the study from the Infectious Diseases Institute and Butabika hospital. Besides publication of the work in reputable peer-reviewed journals, we hope that this work will lead to evidence-based discussions on the need for early interventions to reduce DUP in Uganda.

Assessing social recovery of vulnerable youth in global mental health settings: a pilot study of clinical research tools in Malaysia

BACKGROUND

A social recovery approach to youth mental health focuses on increasing the time spent in valuable and meaningful structured activities, with a view to preventing enduring mental health problems and social disability. In Malaysia, access to mental health care is particularly limited and little research has focused on identifying young people at risk of serious socially disabling mental health problems such as psychosis. We provide preliminary evidence for the feasibility and acceptability of core social recovery assessment tools in a Malaysian context, comparing the experiential process of engaging young Malaysian participants in social recovery assessments with prior accounts from a UK sample.

METHODS

Nine vulnerable young people from low-income backgrounds were recruited from a non-government social enterprise and partner organisations in Peninsular Malaysia. Participants completed a battery of social recovery assessment tools (including time use, unusual experiences, self-schematic beliefs and values). Time for completion and completion rates were used as indices of feasibility. Acceptability was examined using qualitative interviews in which participants were asked to reflect on the experience of completing the assessment tools. Following a deductive approach, the themes were examined for fit with previous UK qualitative accounts of social recovery assessments.

RESULTS

Feasibility was indicated by relatively efficient completion time and high completion rates. Qualitative interviews highlighted the perceived benefits of social recovery assessments, such as providing psychoeducation, aiding in self-reflection and stimulating goal setting, in line with findings from UK youth samples.

CONCLUSIONS

We provide preliminary evidence for the feasibility and acceptability of social recovery assessment tools in a low-resource context, comparing the experiential process of engaging young Malaysian participants in social recovery assessments with prior accounts from a UK sample. We also suggest that respondents may derive some personal and psychoeducational benefits from participating in assessments (e.g. of their time use and mental health) within a social recovery framework.

Effects of Prodromal Stage and Untreated Psychosis on Subsequent Psychopathology of Schizophrenia: A Path Analysis

BACKGROUND

To examine psychopathology present under prolonged antipsychotic treatment in schizophrenia and to analyse their relationship to both the duration of the prodromal stage (DPS; time between onset of first unspecific psychological symptoms and first schizophrenic symptoms) and the duration of untreated psychosis (DUP; time between the onset of psychosis and the initiation of antipsychotic treatment).

METHODS

The psychopathology of 93 patients was assessed cross-sectionally using the Scales for the Assessment of Negative and Positive Symptoms and the Brief Psychiatric Rating Scale. DPS and DUP were assessed by means of the patient records and the Interview for the Retrospective Assessment of the Onset and Course of Schizophrenia and Other Psychoses. A path analysis using maximum likelihood estimation was conducted with the program Analysis of Moment Structures for Windows.

RESULTS

The resulting path model indicated that DPS was predictive for a more severe negative symptomatology in schizophrenia, whereas DUP was associated with a more severe positive symptomatology in the long-term. Furthermore, DUP showed an inverse correlation with the age of the patients at the onset of both first unspecific psychological symptoms and first schizophrenic symptoms.

CONCLUSION

A long prodromal stage suggests an increased risk of a long-term progression with negative symptoms in schizophrenia, whereas a delayed start of antipsychotic treatment could lead to an increased manifestation and severity of positive symptoms in the long term. These results underline the need to shorten the duration of the prodrome by an early detection and adequate intervention in patients with increased risk to develop psychosis.

The family-oriented open dialogue approach in the treatment of first-episode psychosis: Nineteen-year outcomes

Open Dialogue (OD) is a family-oriented early intervention approach which has demonstrated good outcomes in the treatment of first-episode psychosis (FEP). Nevertheless, more evidence is needed. In this register-based cohort study the long-term outcomes of OD were evaluated through a comparison with a control group over a period of approximately 19 years. We examined the mortality, the need for psychiatric treatment, and the granting of disability allowances. Data were obtained from Finnish national registers regarding all OD patients whose treatment for FEP commenced within the time of the original interventions (total N = 108). The control group consisted of all Finnish FEP patients who had a follow-up of 19-20 years and who were guided to other Finnish specialized mental healthcare facilities (N = 1763). No difference between the samples was found regarding the annual incidence of FEP, the diagnosis, and suicide rates. Over the entire follow-up, the figures for durations of hospital treatment, disability allowances, and the need for neuroleptics remained significantly lower with OD group. Findings indicated that many positive outcomes of OD are sustained over a long time period. Due to the observational nature of the study, randomized trials are still needed to provide more information on effectiveness of approach.

Duration of untreated psychosis (DUP) and outcome of people with schizophrenia in rural China: 14-year follow-up study

This study aims to examine the relationship between the duration of untreated psychosis (DUP) and 14-year outcomes of schizophrenia in a Chinese rural area. Participants with schizophrenia (n = 510) were identified in an epidemiological investigation of 123 572 people aged 15 years and older in 1994 and followed up in 2008 in Xinjin, Chengdu, China. Longer DUP (>6 months) was common in participants (27.3%). In 1994, participants with DUP ≤ 6 months were more likely to have a significantly lower rate of suicide attempts, shorter duration of illness and higher rate of full remission compared with those with DUP > 6 months. No significant differences were found regarding the rates of survival, suicide, death due to other causes and homelessness between individuals with shorter and longer DUP in 2008. Nevertheless, longer DUP (>6 months) of participants in 2008 was significantly associated with higher mean of PANSS total negative and general mental scores, longer duration of illness and higher rate of live alone in the logistic regression model. Earlier identification, treatment and rehabilitation, and family intervention should be addressed when developing mental health policies and delivering community mental health services.

Secondary school teachers and mental health competence: Italy-United Kingdom comparison

AIM

The aim of this study was to evaluate the differences between teachers' knowledge about early psychosis among three different Italian cities and a UK sample.

METHODS

The sample consisted of 556 secondary school teachers from three different cities in Italy (Milan, Rome and Lamezia Terme) and London (UK). The research was based on the Knowledge and Experience of Social Emotional Difficulties Among Young People Questionnaire. The Italian version of the questionnaire was used in Italy.

RESULTS

Overall, 67.6% of English teachers, 58.5% of Milan's teachers, 41.8% of Rome's teachers and 33.3% of Lamezia Terme's teachers were able to recognize psychotic symptoms from a case vignette. Logistic regression analysis showed that 'city' was the only independent variable significantly related to the correct/wrong answer about diagnosis.

CONCLUSIONS

We found statistically significant differences between the three Italian samples and the UK sample regarding teachers' knowledge about first signs of psychosis. English teachers showed a better knowledge than Italian teachers in general. Teachers from Milan, where a specific early detection program was established in 2000, seemed to be more familiar with early signs of psychosis than teachers in the other two Italian towns.

Cognitive function in early psychosis patients from a lower middle-income country

OBJECTIVES

To establish evidence of cognitive changes in early psychosis (EP) patients compared to healthy controls (HC) in Pakistan.

METHODS

Fifty-one participants with EP were recruited from psychiatric units in Karachi and Rawalpindi, Pakistan and matched with 51 HC. Neurocognitive domains were assessed using standardised neuropsychological tests [the Stroop test, block design, Matrix Reasoning, picture completion, object assembly, oral fluency, memory for design, Coughlan learning task (verbal and visual)].

RESULTS

EP patients had higher scores than controls for both Stroop tests (T1: EP = 122 HC = 65, p <.001; T2: EP = 190 HC = 153, p = .007) and memory for design test (EP = 10 HC = 3, p = .005). EP group had lower values for block design (EP = 4, HC = 11, p = .01), category fluency (EP = 18.9, HC = 26.1, p < .001), Coughlan verbal tasks (EP = 36.4 NC = 51.5, p < .001), matrix reasoning (EP = 4 NC = 10, p < .001), picture completion (EP = 4 NC = 6, p = .003) and object assembly (EP = 10.7, HC = 15.5, p = .002). There were limited significant associations between cognitive performance and PANSS scores.

CONCLUSIONS

Reduced cognitive performance was found across multiple domains in Pakistani EP patients, which suggests that impaired cognitive performance is homogenous in patients with schizophrenia, regardless of ethnicity.

Reactions to symptoms of mental disorder and help seeking in Sabah, Malaysia

BACKGROUND

A better understanding is needed about how people make decisions about help seeking.

MATERIALS

Focus group and individual interviews with patients, carers, healthcare staff, religious authorities, traditional healers and community members.

DISCUSSION

Four stages of help seeking were identified: (1) noticing symptoms and initial labelling, (2) collective decision-making, (3) spiritual diagnoses and treatment and (4) psychiatric diagnosis and treatment.

CONCLUSION

Spiritual diagnoses have the advantage of being less stigmatising, giving meaning to symptoms, and were seen to offer hope of cure rather than just symptom control. Patients and carers need help to integrate different explanatory models into a meaningful whole.

Early intervention in psychosis: strengths and limitations of services

Early intervention services were established on the basis of a number of fundamental principles, including the notions that intervening in the early stages of psychosis alters illness trajectory and prognosis, that multicomponent interventions promote psychosocial recovery and reduce iatrogenic damage, and that early targeting of non-responders reduces treatment resistance. There is growing evidence of the benefits of specialised early intervention services. These include improved clinical, social and vocational outcomes, reduced in-patient stays and better engagement. Early intervention services can also significantly reduce the risk of a second episode and are highly valued by service users and carers. Duration of treatment appears to determine long-term outcome and there remains uncertainty about how long such intensive intervention should last and whether all patients need the same length of care. Budgetary constraints are pervasive and are particularly likely to affect prodrome clinics and community awareness programmes.

Protective Factors for Early Psychotic Phenomena Among Children of Mothers With Psychosis

Background: Early identification of sub-clinical psychotic experiences in at-risk individuals is vital to prevent the development of psychosis, even before prodromal symptoms emerge. A widely-replicated risk factor is having a family member with psychosis. The Environmental Risk (E-Risk) Longitudinal Twin Study has shown that better cognitive functioning, a stimulating family environment, and a cohesive community, are protective against psychotic experiences among children; while engaging in physical activity, social support, and a cohesive community are protective for adolescents. In the current study we investigate whether these factors also protect against the development of sub-clinical psychotic phenomena among children and adolescents in this cohort who are at high-risk of psychosis by having a mother with psychosis. Methods: Data were utilized from the E-Risk Longitudinal Twin Study, a nationally-representative cohort of 2,232 twin children born in England and Wales in 1994-1995 followed to age 18. Psychotic phenomena were assessed in private interviews with children at ages 12 and 18, and mothers were interviewed about their own experiences of psychosis when children were aged 10 and 12. Bivariate and multivariate logistic regression analyses explored associations between individual, family, and community-level putative protective factors and absence of age-12 psychotic symptoms and age-18 psychotic experiences in children whose mothers had a diagnosis of a psychosis-spectrum disorder and/or reported psychotic symptoms. Results: Higher IQ (OR = 0.97, 95% CI 0.94-1.00, P = 0.036) and living in a more socially cohesive neighborhood (OR = 0.88, 95% CI 0.79-0.98, P = 0.023) were independently protective against age-12 psychotic symptoms among children of mothers with psychosis. Higher levels of perceived social support were independently protective against age-18 psychotic experiences among children of mothers with psychosis (OR = 0.92, 95% CI 0.87-0.98, P = 0.006). However, there were no significant interactions between these protective factors and maternal psychosis in relation to an absence of childhood or adolescent psychotic phenomena in the full sample, indicating that protective effects were not specific to this group of high-risk children. Conclusions: These findings provide preliminary evidence that preventive interventions for early psychotic phenomena could focus on improving cognition, social support, and cohesiveness of the local community. Given scarce resources these might usefully be targeted at high-risk children.

Duration and frequency mismatch negativity shows no progressive reduction in early stages of psychosis

The auditory mismatch negativity (MMN) is a component of event-related potentials, which is being increasingly recognized as a candidate biomarker for early stages of psychosis. Although previous cross-sectional studies have demonstrated small MMN amplitude in early stages of psychosis, it remains unknown whether small MMN amplitude is due to progressive reduction during the early course. In this study, we investigated longitudinal changes of MMN in early stages of psychosis. Participant included 14 patients with first-episode psychosis (FEP), 16 individuals with ultra-high risk (UHR), and 16 healthy control subjects (HC). We measured MMN in response to duration deviants (dMMN) and that in response to frequency deviants (fMMN), respectively. The amplitudes of dMMN in FEP and UHR were significantly smaller in comparison to those in HC, which did not show a progressive decrease over time. The amplitude of fMMN did not differ among groups, which again did not show progression. There was no significant correlation between the length of the follow-up period and the longitudinal change of either deviant-type MMN in the FEP or UHR. These results suggest that dMMN is a trait marker in the early stages of psychosis, and that small dMMN amplitude in early stages of psychosis may reflect altered developmental process rather than progressive brain pathology. The amplitude of fMMN may not alter in early stages of psychosis. These findings may contribute to the future establishment of MMN as a biomarker in early stages of psychosis.
