Early intervention in psychosis: concepts, evidence and future directions

Involuntary admissions for non-affective psychotic disorders in young refugees and peers in Denmark: A population cohort study

INTRODUCTION

People with psychotic disorders are at increased risk of experiencing involuntary hospital admissions relative to other psychiatric patients. Within this group, refugees and other minority groups may be at even greater risk. However, little is known about the role of migration background in the risk of involuntary admissions around the time of first psychosis-related treatment.

METHOD

We utilized nationwide administrative data from Denmark covering the period 2006-2018. We included all persons aged 18-35 years in first treatment for psychotic disorders [inpatient and hospital-based outpatient settings (N = 11,871)]. We estimated odds ratios (OR) of any involuntary inpatient admission within three months of first treatment using logistic regression, and rate ratios (RR) of further involuntary admissions, total number of involuntary admissions, and days of involuntary care among patients initially admitted involuntarily using Poisson regression. We compared refugees with majority peers (native-born with native-born parent), other migrants, and descendants of non-refugee migrants.

RESULTS

Compared with the majority group, refugees, non-refugee migrants and descendants were at increased risk of involuntarily admissions (ORrange = 2.12-2.69). Differences in sex, age, education, household income and family situation did not explain these disparities. In contrast, the risk of subsequent involuntary care did not differ between groups (RRrange = 0.77-1.31).

CONCLUSIONS

The findings highlight the need to review if and why processes of needs detection and voluntary treatment enrolment are less effective for minorities in Denmark. Further studies should investigate the pathways to care across population groups to inform interventions that address disparities.

An analysis of financial hardship faced by patients with First Episode Psychosis, and their families, in an Indian setting

BACKGROUND

The economic burden of psychotic disorders is not well documented in LMICs like India, due to several bottlenecks present in Indian healthcare system like lack of adequate resources, low budget for mental health services and inequity in accessibility of treatment. Hence, a large proportion of health expenditure is paid out of pocket by the households.

OBJECTIVE

To evaluate the direct and indirect costs incurred by patients with First Episode Psychosis and their families in a North Indian setting.

METHOD

Direct and Indirect costs were estimated for 87 patients diagnosed at AIIMS, New Delhi with first-episode psychosis (nonaffective) in the first- and sixth month following diagnosis, and the six months before diagnosis, using a bespoke questionnaire. Indirect costs were valued using the Human Capital Approach.

RESULTS

Mean total costs in month one were INR 7991 ($107.5). Indirect costs were 78.3% of this total. Productivity losses was a major component of the indirect cost. Transportation was a key component of direct costs. Costs fell substantially at six months (INR 2732, Indirect Costs 61%). Respondents incurred substantial costs pre-diagnosis, related to formal and informal care seeking and loss of income.

CONCLUSION

Families suffered substantial productivity loss. Care models and financial protection that address this could substantially reduce the financial burden of mental illness. Measures to address disruption to work and education during FEP are likely to have significant long-term benefits. Families also suffered prolonged income loss pre-diagnosis, highlighting the benefits of early and effective diagnosis.

Incidence of non-affective psychotic disorders in refugees and peers growing up in Denmark and Sweden: a registry linkage study

PURPOSE

Higher rates of non-affective psychotic disorders (NAPD) in minority groups have been reported in many countries. However, few studies have explored how rates differ between refugees and other minority groups and none with an international comparative angle. A comparative perspective makes it possible to relate group differences to aspects national context that underpin the social determinants of disease.

METHODS

We compared the incidence of treated NAPD among youth born in or who immigrated to Denmark/Sweden before turning 18. Youth aged 18-35 during 2006-2018 were included (NDenmark/NSweden = 1,606,423/2,614,721) and were followed until first NAPD treatment (cases [Denmark/Sweden] = 12,193/9,641), 36th birthday, emigration or death. Incidence rates (IR) and ratios (IRR) comparing refugees, non-refugee migrants, descendants of non-refugee migrants and majority youth were obtained through Poisson regression on data aggregated by country, sex and age, contrasted by sex and country. Complementary analyses on individual-level data adjusting for further socio-demographic factors were conducted in each country separately.

RESULTS

Incidence rates were higher in all groups compared with the majority group (IRRrange = 1.4-2.9, 95% CI[min, max] = 1.2-3.1). Relative differences between the three minority groups were smaller (IRRrange = 0.7-1.0, 95% CI[min, max] = 0.5-1.2). Although incidence rates were higher in Denmark than Sweden, relative group differences were similar.

CONCLUSION

Exposures shared between young refugees and other minority groups growing up in Denmark and Sweden may be especially important for their excess risk of NAPD. Further studies should investigate the mechanisms behind the elevated rates in minority groups with special paid attention to factors such as discrimination, social exclusion and acculturation stress.

How "global" is research in early intervention for psychosis? A bibliometric analysis

INTRODUCTION

Unlike high-income countries (HICs), there are few early intervention services for psychosis in low-and middle-income countries (LAMICs). In HICs, research spurred the growth of such services. Little is known about the state of EIP research in LAMICs, which we address by examining their research output and collaborations vis-à-vis that of HICs.

METHODS

We conducted a search in Scopus database for early psychosis publications in scientific journals since 1980. Data from each record, including title, author affiliation, and date, were downloaded. For HIC-LAMIC collaborations, data on first, corresponding and last authors' affiliations, and funding were manually extracted. Descriptive statistics and social network analysis were conducted.

RESULTS

Globally, early psychosis publications increased from 24 in 1980 to 1297 in 2022. Of 16,942 included publications, 16.1 % had LAMIC authors. 71.3 % involved authors from a single country (regardless of income level). 21.9 % were collaborations between HICs, 6.6 % between HICs and LAMICs, and 0.2 % among LAMICs. For research conducted in LAMICs and involving HIC-LAMIC collaborations, the first, last, and corresponding authors were LAMIC-based in 71.8 %, 60.7 %, and 63.0 %, respectively. These positions were dominated (80 %) by authors from four LAMICs. 29.4 % of the HIC-LAMIC subset was funded solely by LAMIC funders, predominantly two LAMICs.

CONCLUSIONS

LAMICs are starkly underrepresented in the otherwise flourishing body of early psychosis research. They have far fewer collaborations and less funding than HICs. Closing these gaps in LAMICs where most of the world's youth live is imperative to generate the local knowledge needed to strengthen early psychosis services that are known to improve outcomes.

The key role of specific DSM-5 diagnostic criteria in the early development of alcohol use disorder: Findings from the RADAR prospective cohort study

BACKGROUND

Prevention and early intervention of alcohol use disorder (AUD) is a public health priority, yet there are gaps in our understanding of how AUD emerges, which symptoms of AUD come first, and whether there are modifiable risk factors that forecast the development of the disorder. This study investigated potential early-warning-sign symptoms for the development of AUD.

METHODS

Data were from the RADAR study, a prospective cohort study of contemporary emerging adults across Australia (n = 565, mean age = 18.9, range = 18-21 at baseline, 48% female). Participants were interviewed five times across a 2.5-year period. Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) AUD criteria and diagnoses were assessed by clinical psychologists using the Structured Clinical Interview for DSM-IV (SCID-IV), modified to cover DSM-5 criteria. Hazard analyses modeled the time from first alcoholic drink to the emergence of any AUD criteria and determined which first-emergent AUD criteria were associated with a faster transition to disorder.

RESULTS

By the final time point, 54.8% of the sample had experienced at least one DSM-5 AUD criterion and 26.1% met criteria for DSM-5 AUD. The median time from first AUD criterion to a diagnosis of AUD was 4 years. Social problems from drinking (hazard ratio [HR] = 3.24, CI95 = 2.14, 4.92, p < 0.001), major role (HR = 2.53, CI95 = 1.58, 4.06, p < 0.001), and drinking larger amounts/for longer than intended (HR = 2.04, CI95 = 1.20, 3.46, p = 0.008) were first-onset criteria associated with a faster transition to AUD.

CONCLUSION

In the context of a prospective general population cohort study of the temporal development of AUD, alcohol-related social problems, major role problems, and using more or for longer than intended are key risk factors that may be targeted for early intervention.

Patient- and family-reported experiences of their treating teams in early psychosis services in Chennai, India and Montreal, Canada

BACKGROUND

Cross-cultural psychosis research has mostly focused on outcomes, rather than patient and family experiences. Therefore, our aim was to examine differences in patients' and families' experiences of their treating teams in early intervention services for psychosis in Chennai, India [low- and middle-income country] and Montreal, Canada [high-income country].

METHODS

Patients (165 in Chennai, 128 in Montreal) and their families (135 in Chennai, 110 in Montreal) completed Show me you care, a patient- and family-reported experience measure, after Months 3, 12, and 24 in treatment. The measure assesses the extent to which patients and families view treating teams as being supportive. A linear mixed model with longitudinal data from patient and family dyads was used to test the effect of site (Chennai, Montreal), stakeholder (patient, family), and time on Show me you care scores. This was followed by separate linear mixed effect models for patients and families with age and gender, as well as symptom severity and functioning as time-varying covariates.

RESULTS

As hypothesized, Chennai patients and families reported more supportive behaviours from their treating teams (β=4.04; β= 9, respectively) than did Montreal patients (Intercept =49.6) and families (Intercept=42.45). Higher symptom severity over follow-up was associated with patients reporting lower supportive behaviours from treating teams. Higher levels of positive symptoms (but lower levels of negative symptoms) over follow-up were associated with families reporting lower supportive behaviours from treating teams. There was no effect of time, age, gender and functioning.

CONCLUSIONS

The levels to which treating teams are perceived as supportive may reflect culturally shaped attitudes (e.g., warmer attitudes towards healthcare providers in India vis-à-vis Canada) and actual differences in how supportive treating teams are, which too may be culturally shaped. Being expected to be more involved in treatment, Chennai families may receive more attention and support, which may further reinforce their involvement. Across contexts, those who improve over follow-up may see their treating teams more positively.

Disengagement from the Ribeirão Preto early intervention program for psychosis: A retrospective cohort study

BACKGROUND

Treatment discontinuation within Early Intervention Services (EIS) for psychosis poses a significant challenge to achieving better outcomes in the early stages of psychotic disorders. Prevalence and predictors of early disengagement from EIS located in low- and middle-income countries (LMICs) remain poorly investigated. We aimed to examine the rates and predictors of disengagement from the Ribeirão Preto Early Intervention Program for Psychosis (Ribeirão Preto-EIP) in Brazil.

METHODS

We conducted a retrospective cohort study using data from patients referred to the Ribeirão Preto-EIP between January 01, 2015, and December 31, 2018. Exclusion criteria were individuals with a single consultation, a diagnosis other than a psychotic disorder, and documented cases of death.

RESULTS

Our sample comprised 234 patients, with an overall median follow-up time of 14.2 months. Early treatment disengagement was observed in 26.5 % (n=62), with a median time to disengagement of 5.25 months. Univariable analysis identified non-white skin color (HR=2.10, 95 %CI 1.26-3.49), positive THC screening (HR=2.22, 95 %CI 1.23-4.01), and substance-induced psychosis (HR=2.15, 95 %CI 1.10-4.21) as significant predictors. In multivariable analysis, only non-white skin color remained a significant predictor of early disengagement (HR=1.87, 95 %CI 1.08-3.27).

CONCLUSIONS

The observed rates of early disengagement in our sample are similar to those reported in wealthy countries, but higher than previously reported for LMICs. Non-white skin color predicted early disengagement in our sample, probably due to social disadvantages. Our data highlights the need for enhanced research elucidating the specific features of EIS in LMICs.

Two people making sense of a story: narrative exposure therapy as a trauma intervention in early intervention in psychosis

Background: Narrative exposure therapy (NET) is a recommended intervention for people with multiple trauma histories; however, research is lacking into its use with people experiencing psychosis, many of whom report multiple trauma histories.Objective: This study aimed to explore experiences of NET in early intervention in psychosis (EIP) services.Method: Eight clinicians and four experts with lived experience (experts by experience) of psychosis and multiple trauma were interviewed on a single occasion using two versions (clinician and expert by experience) of a semi-structured interview schedule. Data was analysed using thematic analysis.Results: Five overarching themes were generated, relating to fear and avoidance of memories, importance of trust, organizing memories and making new meaning, reconnecting with emotions, and considerations when delivering NET in EIP.Conclusions: Directly addressing the impact of multiple trauma in people experiencing first episode psychosis is frightening and emotive, but helps to address painful memories and organize them into a personal narrative. Increases in distress and anomalous experiences were carefully considered by clinicians, but typically outweighed by the benefits of NET. Challenges were comparable to those described in non-psychosis research. Implications for clinical practice and future research are outlined.

Referral pathways to early intervention services for psychosis and their influence on perceptions of care: An interpretive phenomenological analysis

AIM

Most young adults experiencing psychosis enter early intervention services (EIS) via inpatient and emergency departments. These experiences are suggested to negatively impact their views of treatment and engagement in EIS. However, limited research has examined the impact of young adults' prior help-seeking experiences on these outcomes. The present study aimed to explore how young adults engaged in EIS have experienced initial help-seeking and make sense of these experiences in the context of their current treatment.

METHODS

Using an interpretative phenomenological analysis approach, semi-structured interviews were conducted with 12 young adults (mean age = 24.83) within their first 3-12 months of treatment in EIS. Interviews aimed to examine their experiences of help-seeking and referral to EIS as well as the impact of these experiences on their subsequent perception of, and engagement with EIS.

RESULTS

3 superordinate themes emerged: (1) Navigating the Maze of Healthcare (2) Dignity and (3) Impact of Help-Seeking and Referral Experiences. Participants with referral pathways involving urgent care services described more adversity during their referral pathway and tended to describe help-seeking experiences as contributing to negative views towards EIS and diminished engagement in treatment.

CONCLUSIONS

The impact of early negative experiences with healthcare on views towards EIS and engagement is evident in participants' accounts. Sense making was further contextualized by participants' illness insight, degree of recovery, and social support throughout experiences. Emergent themes highlight the need for psychiatric services to emphasize service users' dignity and for EIS to provide opportunities for patients to process past negative mental healthcare experiences to strengthen engagement.

Psychometric properties of the Spanish version of the measure of insight into cognition-self-report in psychosis-risk and non-clinical Mexican young adults

AIM

Cognitive disturbances typically precede the onset of overt psychotic symptoms and represent a neurobiological marker for psychosis risk that is also associated with poor functional outcomes. The Measure of Insight into Cognition-Self Report (MIC-SR) is a widely used 12-item questionnaire that assesses the perceived frequency of cognitive impairment in the domains of executing functioning, attention, and memory. However, the MIC-SR is not available in Spanish, one of the most widely spoken languages worldwide. The present study aimed to provide a Spanish version of the MIC-SR and examine its psychometric properties in psychosis-risk and non-clinical Mexican young adults.

METHODS

The sample comprised 621 participants who completed a battery of self-report measures via an online survey. Of the participants, 478 were non-clinical, and 143 met the screening criteria for a clinical high-risk for psychosis (CHR-positive).

RESULTS

Confirmatory Factor Analyses supported a one-factor model, consistent with the findings for the original MIC-SR. The results showed adequate fit indices for the general model and the independent models for both groups, with high Cronbach's alpha coefficients. Furthermore, the CHR-positive group showed more frequent subjective cognitive problems on each of the 12 items, higher total scores, and higher average frequency than the non-clinical group.

CONCLUSION

To our knowledge, this is the first translation of the MIC-SR into Spanish. Using the MIC-SR at the CHR stage may contribute to our understanding of cognitive processes associated with the onset of a psychotic disorder and provide valuable information in the context of detection and early intervention efforts.

Effects of diazepam on hippocampal blood flow in people at clinical high risk for psychosis

Elevated hippocampal perfusion has been observed in people at clinical high risk for psychosis (CHR-P). Preclinical evidence suggests that hippocampal hyperactivity is central to the pathophysiology of psychosis, and that peripubertal treatment with diazepam can prevent the development of psychosis-relevant phenotypes. The present experimental medicine study examined whether diazepam can normalize hippocampal perfusion in CHR-P individuals. Using a randomized, double-blind, placebo-controlled, crossover design, 24 CHR-P individuals were assessed with magnetic resonance imaging (MRI) on two occasions, once following a single oral dose of diazepam (5 mg) and once following placebo. Regional cerebral blood flow (rCBF) was measured using 3D pseudo-continuous arterial spin labeling and sampled in native space using participant-specific hippocampus and subfield masks (CA1, subiculum, CA4/dentate gyrus). Twenty-two healthy controls (HC) were scanned using the same MRI acquisition sequence, but without administration of diazepam or placebo. Mixed-design ANCOVAs and linear mixed-effects models were used to examine the effects of group (CHR-P placebo/diazepam vs. HC) and condition (CHR-P diazepam vs. placebo) on rCBF in the hippocampus as a whole and by subfield. Under the placebo condition, CHR-P individuals (mean [±SD] age: 24.1 [±4.8] years, 15 F) showed significantly elevated rCBF compared to HC (mean [±SD] age: 26.5 [±5.1] years, 11 F) in the hippocampus (F(1,41) = 24.7, pFDR < 0.001) and across its subfields (all pFDR < 0.001). Following diazepam, rCBF in the hippocampus (and subfields, all pFDR < 0.001) was significantly reduced (t(69) = -5.1, pFDR < 0.001) and normalized to HC levels (F(1,41) = 0.4, pFDR = 0.204). In conclusion, diazepam normalized hippocampal hyperperfusion in CHR-P individuals, consistent with evidence implicating medial temporal GABAergic dysfunction in increased vulnerability for psychosis.

Metacognition as a Transdiagnostic Determinant of Recovery in Schizotypy and Schizophrenia Spectrum Disorders

The term schizotypy refers to the latent personality organization that is thought to underpin the liability to develop schizophrenia and associated disorders. Metacognition, or the ability to understand and form increasingly complex and integrated ideas of oneself, others, and one's community, has been proposed to be an important transdiagnostic construct across schizophrenia spectrum disorders and a range of both clinical and non-clinical manifestations of schizotypy. In this paper, we review evidence that deficits in metacognition are present in individuals with relatively high levels of schizotypy and that these deficits are related to symptomology, function, and quality of life. We address the idea that decrements in metacognition may also contribute to the progression from schizotypy to more severe manifestations, while the amelioration of these deficits may enhance aspects of recovery, including the ability to form an integrated sense of self, others, and the wider world. We also review the following two recovery-oriented psychotherapies that target metacognition to promote recovery in individuals with clinical manifestations of schizotypy: Evolutionary Systems Therapy for Schizotypy (ESTS) and Metacognitive Reflection and Insight Therapy (MERIT).

The (cost-)effectiveness of early intervention (MBT-early) versus standard protocolized treatment (CBT) for emerging borderline personality disorder in adolescents (the EARLY study): a study protocol for a randomized controlled trial

BACKGROUND

Although clinical guidelines prioritize the treatment of depression and anxiety in young persons, there is accumulating evidence that the presence of symptoms of borderline personality disorder (BPD) is associated with the limited effectiveness of these standard treatments. These findings stress the need for interventions addressing early-stage BPD in young people with presenting symptoms of anxiety and depressive disorders. The aim of this study is to investigate the (cost-)effectiveness of an early intervention programme for BPD (MBT-early) compared to first-choice psychological treatment for depression and anxiety according to Dutch treatment guidelines (CBT), in adolescents with either depression, anxiety, or both, in combination with early-stage BPD.

METHODS

This study is a multi-centre randomized controlled trial. A total of 132 adolescents, presenting with either depression, anxiety, or both and significant BPD features will be randomized to either MBT-early or CBT. The severity of BPD, symptoms of depression and anxiety, personality, social and academic functioning, and quality of life will be assessed at baseline, end of treatment, and at 12-, 18-, and 24-month follow-up, along with medical costs and costs of productivity losses for cost-effectiveness analyses.

DISCUSSION

This study will provide an empirical evaluation of the potential surplus value of early intervention in young people for whom treatment oriented at common mental disorders like anxiety and depression may be insufficient given their underlying personality problems.

Increased risk of psychiatric disorder in patients with hearing loss: a nationwide population-based cohort study

BACKGROUND

Hearing loss has been shown to be a risk factor for psychiatric disorders. In addition, long-term hearing loss is associated with increased hospitalization and mortality rates; however, the increased risk and duration of effect of hearing loss in combination with other chronic diseases on each psychiatric disorder are still not clearly defined. The purpose of this article is to clarify the risk of hearing loss for each disorder over time.

METHODS

This was a retrospective cohort study, and a national health insurance research database in Taiwan was utilized. All (n = 1,949,101) Taiwanese residents who had a medical visit between 2000 and 2015 were included. Patients with hearing loss and a comparative retrospective cohort were analyzed. Every subject was tracked individually from their index date to identify the subjects who later received a diagnosis of a psychiatric disorder. The Kaplan‒Meier method was used to analyze the cumulative incidence of psychiatric disorders. Cox regression analysis was performed to identify the risk of psychiatric disorders.

RESULTS

A total of 13,341 (15.42%) and 31,250 (9.03%) patients with and without hearing loss, respectively, were diagnosed with psychiatric disorders (P < 0.001). Multivariate analysis indicated that hearing loss significantly elevated the risk of psychiatric disorders (adjusted HR = 2.587, 95% CI 1.723-3.346, p < 0.001).

CONCLUSION

Our findings indicate that patients with hearing loss are more likely to develop psychiatric disorders. Furthermore, the various psychiatric disorders are more likely to occur at different times. Our findings have important clinical implications, including a need for clinicians to implement early intervention for hearing loss and to pay close attention to patients' psychological status.

Psychopathology and psychosocial functioning among young people with first-episode psychosis and/or first-presentation borderline personality disorder

BACKGROUND

One in five young people with first-episode psychosis (FEP) also presents with borderline personality disorder (BPD) features. Among people diagnosed with BPD, auditory verbal hallucinations occur in 29-50 % and delusions in 10-100 %. Co-occurrence of psychotic symptoms and BPD is associated with greater clinical severity and greater difficulty accessing evidence based FEP care. This study aimed to investigate psychotic symptoms and psychosocial functioning among young people presenting to an early intervention mental health service.

METHOD

According to the presence or absence of either FEP or BPD, 141 participants, aged 15-25 years, were assigned to one of four groups: FEP, BPD, combined FEP + BPD, or clinical comparison (CC) participants with neither FEP nor BPD. Participants completed semi-structured diagnostic interviews and interviewer and self-report measures of psychopathology and psychosocial functioning.

RESULTS

The FEP + BPD group had significantly more severe psychopathology and poorer psychosocial functioning than the FEP group on every measure, apart from intensity of hallucinations. Comparing the FEP or BPD groups, the BPD group had greater psychopathology, apart from intensity of psychotic symptoms, which was significantly greater in the FEP group. These two groups did not significantly differ in their overall psychosocial functioning. Compared with CC young people, both the FEP + BPD and BPD groups differed significantly on every measure, with medium to large effect sizes.

CONCLUSIONS

Young people with co-occurring FEP and BPD experience more severe difficulties than young people with either diagnosis alone. This combination of psychosis and severe personality pathology has been longitudinally associated with poorer outcomes among adults and requires specific clinical attention.

The Cost-Effectiveness of a Novel Online Social Therapy to Maintain Treatment Effects From First-Episode Psychosis Services: Results From the Horyzons Randomized Controlled Trial

BACKGROUND

Digital interventions have potential applications in promoting long-term recovery and improving outcomes in first-episode psychosis (FEP). This study aimed to evaluate the cost-effectiveness of Horyzons, a novel online social therapy to support young people aged 16-27 years following discharge from FEP services, compared with treatment as usual (TAU) from a healthcare sector and a societal perspective.

STUDY DESIGN

A cost-effectiveness analysis (CEA), based on the change in social functioning, and a cost-utility analysis (CUA) using quality-adjusted life years were undertaken alongside a randomized controlled trial. Intervention costs were determined from study records; resources used by patients were collected from a resource-use questionnaire and administrative data. Mean costs and outcomes were compared at 18 months and incremental cost-effectiveness ratios were calculated. Uncertainty analysis using bootstrapping and sensitivity analyses was conducted.

STUDY RESULTS

The sample included 170 participants: Horyzons intervention group (n = 86) and TAU (n = 84). Total costs were significantly lower in the Horyzons group compared with TAU from both the healthcare sector (-AU$4789.59; P < .001) and the societal perspective (-AU$5131.14; P < .001). In the CEA, Horyzons was dominant, meaning it was less costly and resulted in better social functioning. In the CUA, the Horyzons intervention resulted in fewer costs but also yielded fewer QALYs. However, group differences in outcomes were not statistically significant. When young people engaged more with the platform, costs were shown to decrease and outcomes improved.

CONCLUSIONS

The Horyzons intervention offers a cost-effective approach for improving social functioning in young people with FEP after discharge from early intervention services.

Seven decades of antipsychotic drugs: Why is the life of Australians with schizophrenia still so suboptimal?

The advent of dopamine (D2) receptor-blocking medications over 70 years ago, ushered in a new era of biological treatment for schizophrenia. However, we argue that little subsequent progress has been made in translating this into fulfilled and fulfilling lives for people with schizophrenia. This Viewpoint asks why this is the case, and suggests ways forward for capitalising on extant and emerging new treatments for psychotic disorders, to the betterment of the lives of people living with schizophrenia.

Prodromal symptoms and the duration of untreated psychosis in first episode of psychosis patients: what differences are there between early vs. adult onset and between schizophrenia vs. bipolar disorder?

To assess the role of age (early onset psychosis-EOP < 18 years vs. adult onset psychosis-AOP) and diagnosis (schizophrenia spectrum disorders-SSD vs. bipolar disorders-BD) on the duration of untreated psychosis (DUP) and prodromal symptoms in a sample of patients with a first episode of psychosis. 331 patients with a first episode of psychosis (7-35 years old) were recruited and 174 (52.6%) diagnosed with SSD or BD at one-year follow-up through a multicenter longitudinal study. The Symptom Onset in Schizophrenia (SOS) inventory, the Positive and Negative Syndrome Scale and the structured clinical interviews for DSM-IV diagnoses were administered. Generalized linear models compared the main effects and group interaction. 273 AOP (25.2 ± 5.1 years; 66.5% male) and 58 EOP patients (15.5 ± 1.8 years; 70.7% male) were included. EOP patients had significantly more prodromal symptoms with a higher frequency of trouble with thinking, avolition and hallucinations than AOP patients, and significantly different median DUP (91 [33-177] vs. 58 [21-140] days; Z = - 2.006, p = 0.045). This was also significantly longer in SSD vs. BD patients (90 [31-155] vs. 30 [7-66] days; Z = - 2.916, p = 0.004) who, moreover had different profiles of prodromal symptoms. When assessing the interaction between age at onset (EOP/AOP) and type of diagnosis (SSD/BD), avolition was significantly higher (Wald statistic = 3.945; p = 0.047), in AOP patients with SSD compared to AOP BD patients (p = 0.004). Awareness of differences in length of DUP and prodromal symptoms in EOP vs. AOP and SSD vs. BD patients could help improve the early detection of psychosis among minors.

Cross-cultural adaptation and inter-rater reliability of the Schizophrenia proneness instrument adult version (SPI-A) in the Indonesian context

This study aims to adapt the Schizophrenia Proneness Instrument, Adult Version (SPI-A) for the assessment of basic symptoms to the Indonesian context (culturally and linguistically) and analyze the inter-rater reliability of the translated version. Following a specific methodology for cultural adaptation, direct and back-translations were conducted together with cognitive interviews to analyze the comprehensibility of the translated version. A linguistic expert analyzes the resulting version to determine its grammatical and linguistic adequacy. Finally, the interclass correlation (ICC) of the three expert ratings of the samples (N = 9) was analyzed. The direct and back-translation phases showed good conceptual equivalence to the original version. The cognitive interviews revealed items that were challenging to understand and required revision. The final version also considered the judgments of a linguistic expert for grammatical and conceptual improvements. Inter-rater reliability analysis showed an excellent degree of agreement (ICC value: 0.984; 95% CI: 0.950-0.996). The translated SPI-A fits the Indonesian context and can be used in clinical settings to assess basic symptoms in help-seeking individuals in Indonesia.

Systematic Review and Meta-analysis: Rates of Violence During First-Episode Psychosis (FEP)

BACKGROUND

Most people with psychotic disorders will never commit an act of violence. However, the risk of violence committed by people with schizophrenia is higher than the general population. Violence risk is also known to be highest during the first episode of psychosis compared to later stages of illness. Despite this, there have been no comprehensive reviews conducted in the past 10 years examining rates of violence during FEP. We aimed to provide an updated review of the rate of violence in people with FEP.

STUDY DESIGN

Meta-analytical techniques were used to identify pooled proportions of violence according to severity (less serious, serious, severe) and timing of violence (before presentation, at first presentation, after presentation to services).

STUDY RESULTS

Twenty-two studies were included. The pooled prevalence was 13.4% (95% CI [9.0%-19.5%]) for any violence, 16.3% (95% CI [9.1%-27.4%]) for less serious violence, 9.7% (95% CI [5.4%-17.0%]) for serious violence and 2.7% for severe violence, regardless of time point. The pooled prevalence of any violence was 11.6% (95% CI [6.8%-18.9%]) before presentation, 20.8% (95% CI [9.8%-38.7%]) at first presentation and 13.3% (95% CI [7.3%-23.0%]) after presentation to services.

CONCLUSION

Overall, rates of violence appear to be lower in more recent years. However, due to the high between-study heterogeneity related to study design, the findings must be interpreted with consideration of sample characteristics and other contextual factors. The prevalence of violence remained high at all-time points, suggesting that more targeted, holistic, and early interventions are needed for clinical FEP groups.

Effect of early intervention for early-stage psychotic disorders on suicidal behaviours - a systematic review protocol

Background

The early stages of psychotic disorders correspond to the early phases of the disease and include the prodromal phase and first-episode psychosis; they constitute a period at high risk of suicidal behaviour. A long duration of untreated psychosis (DUP) is among the risk factors of suicidal behaviour identified in this early period. Many studies have shown the effectiveness of early interventions on the overall prognosis of psychotic disorders in the early stages, and early intervention strategies have been developed and tested worldwide. Several authors reported an improvement in suicidal behaviours; however, all these data have not been systematically analysed yet. The main objective of this systematic review was to collect evidence on the effect on suicidal behaviour of early interventions for patients in the early stages of psychotic disorders.

Methods

We will carry out a systematic review of the literature according to the PRISMA criteria by searching articles in five databases (PubMed, Cochrane, PsycINFO, Scopus, EMBASE), without restriction on the publication date. The selection criteria are: articles (any type; e.g. prospective, retrospective, controlled or uncontrolled, and literature reviews) on early interventions for psychotic disorders in the early stages with data on suicide attempts, death by suicide, suicidal ideation; articles written in English or French. Exclusion criteria are: articles on suicidal behaviours in patients with psychotic disorders in the early stages, but without early intervention, and articles on early-stage psychotic disorders without data on suicidal behaviours.

Discussion

If this review confirms the effectiveness on suicidal behaviours of early interventions for young patients with psychotic disorders, the development/implementation of such intervention programmes should be better promoted.

First-episode psychosis intervention programme versus standard care for the clinical management of early phases of psychosis: cost analysis

BACKGROUND

Early intervention programmes (EIPs) in psychosis have gained attention as specialised interventions to improve health-related and societal impacts for people with psychotic disorders. Previous studies have presented evidence in favour of EIPs over the first year of intervention, despite none considering the critical period before psychosis onset (5 years).

AIMS

To compare the associated costs of the First Episode Psychosis Intervention Program (CRUPEP) and treatment as usual (TAU) in a real-world cohort in a non-specialised psychiatric community setting.

METHOD

Direct and indirect mental health-related costs were calculated over 1 year and up to 7 years. Healthcare and societal costs were calculated from economic data related to the consumption of all healthcare resources, including emergency department attendances, hospital admissions, psychotropic medication prescriptions and societal costs.

RESULTS

From a healthcare perspective, the intervention (CRUPEP) group initially showed a marginally higher cost per patient than the TAU group (€7621 TAU group v. €11 904 CRUPEP group) over the first year of follow-up. However, this difference was reversed between the groups on considering the entire follow-up, with the TAU group showing considerably higher associated costs per patient (€77 026 TAU v. €25 247 CRUPEP).

CONCLUSIONS

The EIP (CRUPEP) showed clinical benefits and minimised the direct and indirect health-related costs of the management of psychosis. Although the CRUPEP intervention initially reported increased costs over 1 year, TAU surpassed the global costs over the entire follow-up.

Early intervention in psychosis services: A systematic review and narrative synthesis of barriers and facilitators to seeking access

BACKGROUND

The duration of untreated psychosis (DUP) continues to be a global priority. Early intervention services were established to reduce treatment delays but have had limited impact. This systematic review examines barriers and facilitators to seeking access to these services, to identify targets for service level change.

METHODS

We conducted a systematic review of relevant databases (PsychINFO, MEDLINE, CINAHL, and PsychARTICLES) using pre-defined search terms for psychosis, early intervention, and barriers and facilitators. Given the majority of qualitative studies, a thematic synthesis rather than meta-analysis was indicated.

RESULTS

The search yielded 10 studies. Mental health stigma and discrimination predict DUP, compounded by structural barriers which limit the impact of early intervention services on timely access to recommended treatments. Synthesis of the qualitative studies generated three themes: knowledge, relationships, and stigma. Lack of knowledge, absence of supportive relationships (social and professional), and self-stigma constitute significant barriers to seeking access to early intervention services.

CONCLUSIONS

This is the first review of the barriers and facilitators to seeking access to early intervention services. The findings highlight public health and secondary care service targets to expedite access to recommended treatments and thereby reduce the DUP.

Risk stratification for treating people at ultra-high risk for psychosis: A cost-effectiveness analysis

People who are at ultra-high risk (UHR) for psychosis receive clinical care with the aim to prevent first-episode psychosis (FEP), regardless of the risk of conversion to psychosis. An economic model from the Canadian health system perspective was developed to evaluate the cost-effectiveness of treating all with UHR compared to risk stratification over a 15-year time horizon, based on conversion probability, expected quality-of-life and costs. The analysis used a decision tree followed by a Markov model. Health states included: Not UHR, UHR with <20 % risk of conversion to FEP (based on the North American Prodrome Longitudinal Study risk calculator), UHR with ≥20 % risk, FEP, Remission, Post-FEP, and Death. The analysis found that: risk stratification (i.e., only treating those with ≥20 % risk) had lower costs ($1398) and quality-adjusted life-years (0.055 QALYs) per person compared to treating all. The incremental cost-effectiveness ratio for 'treat all' was $25,448/QALY, and suggests treating all may be cost-effective. The model was sensitive to changes to the probability of conversion.

Variability in Cognitive Task Performance in Early Adolescence Is Associated With Stronger Between-Network Anticorrelation and Future Attention Problems

Background

Intraindividual variability (IIV) during cognitive task performance is a key behavioral index of attention and a consistent marker of attention-deficit/hyperactivity disorder. In adults, lower IIV has been associated with anticorrelation between the default mode network (DMN) and dorsal attention network (DAN)-thought to underlie effective allocation of attention. However, whether these behavioral and neural markers of attention are 1) associated with each other and 2) can predict future attention-related deficits has not been examined in a developmental, population-based cohort.

Methods

We examined relationships at the baseline visit between IIV on 3 cognitive tasks, DMN-DAN anticorrelation, and parent-reported attention problems using data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 11,878 participants, ages 9 to 10 years, female = 47.8%). We also investigated whether behavioral and neural markers of attention at baseline predicted attention problems 1, 2, and 3 years later.

Results

At baseline, greater DMN-DAN anticorrelation was associated with lower IIV across all 3 cognitive tasks (B = 0.22 to 0.25). Older age at baseline was associated with stronger DMN-DAN anticorrelation and lower IIV (B = -0.005 to -0.0004). Weaker DMN-DAN anticorrelation and IIV were cross-sectionally associated with attention problems (B = 1.41 to 7.63). Longitudinally, lower IIV at baseline was associated with less severe attention problems 1 to 3 years later, after accounting for baseline attention problems (B = 0.288 to 0.77).

Conclusions

The results suggest that IIV in early adolescence is associated with worsening attention problems in a representative cohort of U.S. youth. Attention deficits in early adolescence may be important for understanding and predicting future cognitive and clinical outcomes.

Towards a youth mental health paradigm: a perspective and roadmap

Most mental disorders have a typical onset between 12 and 25 years of age, highlighting the importance of this period for the pathogenesis, diagnosis, and treatment of mental ill-health. This perspective addresses interactions between risk and protective factors and brain development as key pillars accounting for the emergence of psychopathology in youth. Moreover, we propose that novel approaches towards early diagnosis and interventions are required that reflect the evolution of emerging psychopathology, the importance of novel service models, and knowledge exchange between science and practitioners. Taken together, we propose a transformative early intervention paradigm for research and clinical care that could significantly enhance mental health in young people and initiate a shift towards the prevention of severe mental disorders.

Examining Risk Factors for Suicidality in Adolescents and Adults Experiencing Their First Episode of Psychosis

This narrative review aimed to identify the risk factors associated with suicidality in adolescents and adults with first-episode psychosis. The review included studies that examined various factors such as psychiatric, familial, and social factors, as well as previous self-harm, suicidal ideation, and comorbid mental health disorders. A comprehensive literature search was conducted across three publicly available databases (Embase, American Psychological Association PsycINFO, and PubMed) using specific search terms related to first-episode psychosis, suicide, self-harm, and children/adolescents and adults. The inclusion criteria included original articles focusing on prospective and retrospective cohort trials, with substantial data on first-episode psychosis and self-harm, measuring both suicidal intent and outcome. Non-original studies, case reports, case series, non-English-language publications, and studies examining violence and self-harm related to substance-induced psychosis were excluded. After manual screening and removing duplicate articles, 13 articles met the established criteria for inclusion in this review. Included studies adhered to similar inclusion and exclusion criteria, had long-term follow-up, and assessed outcomes at least twice. The findings suggest that depressive symptoms, substance use disorders, previous self-harm or suicidal ideation, and longer duration of untreated psychosis are associated with an increased risk of suicidality. However, insights into psychosis and premorbid intellectual functioning did not show a direct association with suicidality.

Show me you care: A patient- and family-reported measure of care experiences in early psychosis services

AIM

Despite their emphasis on engagement, there has been little research on patients' and families' experiences of care in early intervention services for psychosis. We sought to compare patients' and families' experiences of care in two similar early psychosis services in Montreal, Canada and Chennai, India. Because no patient- or family-reported experience measures had been used in a low- and middle-income context, we created a new measure, Show me you care. Here we present its development and psychometric properties.

METHODS

Show me you care was created based on the literature and stakeholder inputs. Its patient and family versions contain the same nine items (rated on a 7-point scale) about various supportive behaviours of treatment providers towards patients and families. Patients (N = 293) and families (N = 237) completed the measure in French/English in Montreal and Tamil/English in Chennai. Test-retest reliability, internal consistency, convergent validity, and ease of use were evaluated.

RESULTS

Test-retest reliability (intra-class correlation coefficients) ranged from excellent (0.95) to good (0.66) across the patient and family versions, in Montreal and Chennai, and in English, French, and Tamil. Internal consistency estimates (Cronbach's alphas) were excellent (≥0.87). The measure was reported to be easy to understand and complete.

CONCLUSION

Show me you care fills a gap between principles and practice by making engagement and collaboration as central to measurement in early intervention as it is to its philosophy. Having been co-designed and developed in three languages and tested in a low-and-middle-income and a high-income context, our tool has the potential for global application.

The diagnosis that should speak its name: why it is ethically right to diagnose and treat personality disorder during adolescence

Although national guidelines explicitly state that personality disorder can be diagnosed and treated in young people aged 12 to 18 years (adolescents), most clinicians remain hesitant. This creates a gap between science and practice, which we argue is largely motivated by moral reasons and, therefore, is best challenged by ethical arguments. We provide seven arguments in support of the notion that it is ethically right to diagnose and treat personality disorder when it occurs in adolescents. Central to these arguments is the scientific evidence that features of personality disorder are among the best predictors of a complex cluster of psychopathology leading to impairments in many areas of current and future mental, social and vocational functioning. We argue that intervention during adolescence and young adulthood is not only humane, but also critical for efforts to avert the longstanding psychosocial and health problems that seem refractory to treatment in adults with personality disorder. Moreover, we argue that regular services are often inadequately equipped to meet the needs of young people with personality disorder and that the common 'stepped-care' approach should be replaced by a 'staged-care' approach. Finally, we argue that early detection and intervention might have anti-stigmatizing effects, similar to other areas of healthcare in which stigmatizing labels have changed meaning when the conditions to which they refer have become more amenable to treatment.

Pediatrician and Child Adolescent Psychiatrist Perspectives of Coordinated Care for Emerging Adults

PURPOSE

To explore pediatrician and child/adolescent psychiatrists' perspectives of the role of coordinated care for emerging adults with serious mental health conditions, particularly as they transition to adult care.

METHODS

Semi-structured individual interviews of a purposive sample of 10 pediatricians and 11 child/adolescent psychiatrists in Massachusetts were used to explore coordinated care for emerging adults. Following verbatim transcription and double coding, we conducted a thematic analysis to identify key themes. Care coordination concepts explored included a case discussion, teamwork, communication methods, medication management, transition to adult care, the healthcare home, and youth and family role. Organizational and societal barriers were also discussed.

RESULTS

Providers described key barriers to continuous, coordinated care for youth with serious mental health conditions, including poor communication systems between providers, no organized process for the transition from pediatric to adult care, state licensing laws (particularly impacting college-age youth), inadequate connection to community supports, and poor reimbursement rates for psychiatric care. Termination of primary care in young adults and inadequate medication side effect monitoring were described as key gaps in care.

DISCUSSION

The current system of coordinated care for emerging adults with serious mental health conditions is a perfect storm of challenges that creates a vicious cycle of interconnected barriers which lead to fragmented, discontinuous, and sub-par care for this population.

Increased parietal and occipital lobe gyrification predicts conversion to syndromal psychosis in a clinical high-risk cohort

BACKGROUND

Local gyrification index (lGI), indicative of the degree of cortical folding is a proxy marker for early cortical neurodevelopmental abnormalities. We studied the difference in lGI between those who do and do not convert to psychosis (non-converters) in a clinical high-risk (CHR) cohort, and whether lGI predicts conversion to psychosis.

METHODS

Seventy-two CHR participants with attenuated positive symptom syndrome were followed up for two years. The difference in baseline whole-brain lGI was examined on the T1-weighted MRIs between, i)CHR (N = 72) and healthy controls (N = 19), ii)Converters to psychosis (N = 24) and non-converters (N = 48), adjusting for age and sex, on Freesurfer-6.0. The significant cluster obtained in the converters versus non-converters comparison was registered as a region of interest to individual images of all 72 participants and lGI values were extracted from this region. A cox proportional hazards model was applied with these values to study whether lGI predicts conversion to psychosis.

RESULTS

lGI was not different between CHR and healthy controls. lGI was increased in converters in the right-sided inferior parietal and lateral occipital areas (corrected cluster-wise-p-value = 0.009, cohen's f = 0.42) compared to non-converters, which significantly increased the risk of onset of psychosis (p = 0.029, hazard ratio = 1.471).

CONCLUSIONS

Increased gyrification in the right-sided inferior parietal and lateral occipital area differentiates converters to psychosis in CHR, significantly increasing the risk of conversion to psychosis. This measure may reflect underlying traits in parts of the brain that develop earliest in-utero (parietal and occipital), conferring a heightened vulnerability to convert to syndromal psychosis subsequently.

Heterogeneity of quality of life in the later stages of first-episode psychosis recovery

PURPOSE

First-episode psychosis (FEP) is characterised by wide heterogeneity in terms of symptom presentation and illness course. However, the heterogeneity of quality of life (QoL) in FEP is not well understood. We investigated whether subgroups can be identified using participants' responses on four QoL domains (physical health, psychological, social relationships, and environmental) 18-months into the recovery phase of FEP. We then examined the discriminant validity of these subgroups with respect to clinical, cognitive, and functioning features of FEP.

METHOD

Demographic and clinical characteristics, QoL, cognition, and functioning were assessed in 100 people with FEP at the 18-month follow-up of a randomised controlled trial of Individual Placement Support, which aims to facilitate vocational recovery. QoL was measured using the World Health Organisation's QoL-BRIEF. A two-stage clustering approach using Ward's method and Squared Euclidean Distance with a k-means confirmation was conducted. Multinomial logistic regressions were used to establish external validity.

RESULTS

Three QoL subgroups emerged: a 'good' subgroup with relatively high QoL across all domains (31%), an 'intermediate' subgroup with relatively low psychological QoL (48%) and a 'poor' subgroup with markedly low social relationship QoL (21%). Negative symptoms, depressive symptoms, social/occupational functioning, and social inclusion at follow-up predicted subgroup membership. Sensitivity analysis found similar results.

CONCLUSION

Although some individuals with FEP have QoL comparable to individuals without mental ill health, QoL can remain concerningly low despite treatment efforts. Future research on interventions that target factors associated with poor QoL, such as low social inclusion, is required to counteract prolonged poor QoL in FEP.

[Public mental health from an international perspective: from "shifting the curve" to inclusion of vulnerable populations]

In recent years, efforts in the field of public mental health have increased that seek to promote mental health and mental health literacy at population level and yield advances in the prevention, treatment and care of mental health conditions. This paper provides an overview of contemporary conceptualisations of indicators and determinants of public mental health as well as population-based intervention strategies from an international perspective. Current conceptual and methodological challenges of so-called high-risk, whole-population and vulnerable population strategies are critically discussed. Future efforts in research, policy and practice need to address fundamental causes of social and health inequalities, drawing on all societal fields, to contribute to improving population mental health.

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.

Exploring digital cognitive behavioural therapy for insomnia in an early intervention in psychosis service - A study protocol for an initial feasibility study with process evaluation

AIM

Early psychosis may be a critical time at which clinical trajectories are still evolving, and sleep interventions hold promise to improve outcomes at this stage. Although cognitive behavioural therapy (CBT) for insomnia shows promise in psychosis, there has been limited evaluation of delivery within current care. This study aims to evaluate the feasibility and acceptability of providing fully-automated digital CBT for insomnia (CBT-I) within an early intervention in psychosis service.

METHODS

We will conduct a single-arm feasibility trial within an early psychosis intervention service, and up to 40 individuals experiencing a first episode of psychosis and with evidence of insomnia can be enrolled (May 2021 - August 2022). Additional service user inclusion criteria are capacity to consent and access to a suitable technological device to access digital CBT. Participants will be offered access to a fully-automated digital CBT-I program (Sleepio) delivered using web and/or mobile app. The study comprises pre- and post- intervention questionnaire assessments and interviews with service users and staff to provide initial outcome signals.

RESULTS

Quantitative questionnaire data will be analysed descriptively, alongside rates of eligibility, consent, uptake and completion. Qualitative data will be analysed using thematic analysis. Results will be used to develop a logic model describing feasibility and implementation.

CONCLUSIONS

From this study, we hope to better understand how to deliver digital CBT for insomnia within an early intervention in psychosis service. This study will help inform further research, including how best to support staff in using Sleepio, and inform the design of subsequent trials in this area.

Effectiveness of group metacognitive training and cognitive-behavioural therapy in a transdiagnostic manner for young patients with psychotic and non-psychotic disorders

AIM

To investigate group metacognitive training and cognitive-behavioural therapy (MCT/CBT) prospectively in a young population with various psychiatric disorders, including psychotic and mood disorders.

METHODS

This was a prospective study to investigate the effectiveness of group MCT/CBT on quality of life, psychotic symptoms, depression, self-esteem, perceived stress, social function and social cognition. The objective measures included the Positive and Negative Syndrome Scale (PANSS), clinical global impression (CGI), personal and social performance scale for social functioning, a computerized continuous performance test for sustained attention and a computerized emotional recognition test for social cognition. Self-report measures administered included the Subjective Well-being under Neuroleptics for quality of life, Ambiguous Intentions Hostility Questionnaire for suspiciousness, Drug Attitude Inventory, Beck Depression Inventory, Perceived Stress Scale, Brief Resilience Scale, Rosenberg Self-esteem Scale and visual analogue scale for the EQ-5D.

RESULTS

Among 110 young patients with early psychosis and mood disorders who participated, 82 (74.5%) completed the study. Social functioning, quality of life, self-esteem, resilience, depression, suspiciousness, social cognition, sustained attention and scores on the PANSS and CGI improved significantly after completing group MCT/CBT. Perceived stress, resilience and suspiciousness improved significantly only in participants with a non-psychotic disorder. Improvements in subjective well-being of the participants were associated with increases in self-esteem and resilience and decreases in depression and perceived stress.

CONCLUSIONS

Our study showed that group transdiagnostic MCT/CBT for young patients with mental illness improved subjective wellbeing, self-esteem, resilience, social cognition and social functioning and significantly diminished suspiciousness, perceived stress and depression.

Clinical Management and Assessment of the Early Stages of Psychosis: A Multidimensional Approach

Early intervention in psychosis has emerged as an integrated clinical and research strategy for the comprehensive care of people presenting with a first psychotic episode (FEP). In this sense, a multidisciplinary approach is essential for early detection and assessment of preliminary stages of the illness. The main objectives of early intervention programs include the implementation of specialized interventions aimed at promoting functional recovery and improving quality of life. In this chapter, we will describe the main advantages of specialized early intervention programs in psychosis. We will also describe the main aspects of assessment that need to be considered when approaching an FEP.

Reinforcement learning deficits exhibited by postnatal PCP-treated rats enable deep neural network classification

The ability to appropriately update the value of a given action is a critical component of flexible decision making. Several psychiatric disorders, including schizophrenia, are associated with impairments in flexible decision making that can be evaluated using the probabilistic reversal learning (PRL) task. The PRL task has been reverse-translated for use in rodents. Disrupting glutamate neurotransmission during early postnatal neurodevelopment in rodents has induced behavioral, cognitive, and neuropathophysiological abnormalities relevant to schizophrenia. Here, we tested the hypothesis that using the NMDA receptor antagonist phencyclidine (PCP) to disrupt postnatal glutamatergic transmission in rats would lead to impaired decision making in the PRL. Consistent with this hypothesis, compared to controls the postnatal PCP-treated rats completed fewer reversals and exhibited disruptions in reward and punishment sensitivity (i.e., win-stay and lose-shift responding, respectively). Moreover, computational analysis of behavior revealed that postnatal PCP-treatment resulted in a pronounced impairment in the learning rate throughout PRL testing. Finally, a deep neural network (DNN) trained on the rodent behavior could accurately predict the treatment group of subjects. These data demonstrate that disrupting early postnatal glutamatergic neurotransmission impairs flexible decision making and provides evidence that DNNs can be trained on behavioral datasets to accurately predict the treatment group of new subjects, highlighting the potential for DNNs to aid in the diagnosis of schizophrenia.

Effect of individualized occupational therapy on social functioning in patients with schizophrenia: A five-year follow-up of a randomized controlled trial

This study aimed to evaluate the long-term effects of adding individualized occupational therapy (IOT) to a three-months group occupational therapy (GOT) on social functioning in inpatients with schizophrenia or schizoaffective disorder at a follow-up investigation five-years after discharge. Initially, patients were randomly assigned to GOT + IOT or GOT alone, with 102 patients, 48 in GOT + IOT and 54 in GOT alone, completing the five years follow-up. The primary outcome was change in social functioning assessed by the Social Functioning Scale (SFS) from baseline to five-year follow-up. Other outcomes included Brief Assessment of Cognition in Schizophrenia (BACS), Schizophrenia Cognition Rating Scale (SCoRS), Intrinsic Motivation Inventory (IMI), Global Assessment of Functioning (GAF), Positive and Negative Syndrome Scale (PANSS), and Client Satisfaction Questionnaire-8 (CSQ-8). There were significant improvements for the GOT + IOT group over GOT in the SFS total score, which could be explained by improvements in withdrawal/social engagement, interpersonal communication, pro-social activities, recreation, and independence-competence. Multiple regression analysis showed that the period from hospitalization to commencing occupational therapy, type of occupational therapy, BACS motor speed, BACS executive function, and IMI interest/enjoyment were significantly associated with SFS total score. Our findings suggest that adding IOT to GOT may improve the long-term outcome on social functioning in schizophrenic patients. However, the long time period between intervention and follow-up and the unavailability of treatment information during the follow-up period has to be mentioned as a limiting factor of this study.

Evaluating the tendencies of community practitioners who actively practice in child and adolescent psychiatry to diagnose and treat DSM-5 attenuated psychotic syndrome

The detection of individuals at clinical ultra-high risk for psychosis (CHR-P) may be a key limiting step for early interventions, and there is some uncertainty regarding the true clinical reliability of the CHR-P states. The aim of this study was to explore how practitioners who were in the direct treatment of children with psychiatric disorders [child psychiatry specialists/trainees (n = 227, n = 131), adult psychiatrists (n = 27), and child neurologists (n = 2)] perceive the DSM-5-Attenuated Psychosis Syndrome (DSM-5-APS), and their clinical routine practice in the treatment of it. Three vignettes describing fictional cases presented with symptoms of either DSM-5-Schizophrenia, DSM-5-APS, and no psychotic symptoms were created. We asked these practitioners to apply a DSM-5 diagnosis and to choose appropriate treatment(s) for these vignettes. Of the responders, 43% correctly diagnosed the APS vignette, whereas 37.4% mentioned that it had a full-blown psychotic episode. Regarding the therapeutic approach for the APS vignette, 72.1% of all practitioners chose a psychopharmacological intervention and 32% individual psychotherapy. This study showed that the diagnostic inter-rater reliability of the DSM-5-APS among child/adolescent mental health practitioners was consistent with the results from the DSM-5 field trials (Kappa = 0.46). Moreover, almost three in four practitioners endorsed psychopharmacological intervention as a treatment option for the DSM-5-APS case. The lack of evidence of psychopharmacological interventions in CHR-P situations emphasizes that the least harmful interventions should be recommended. Thus, our findings indicated a need for raising awareness regarding the CHR-P paradigm and its treatment as well as the development of solid guidelines that can be implemented in clinical practice.

Prediction of psychosis: model development and internal validation of a personalized risk calculator

BACKGROUND

Over the past two decades, early detection and early intervention in psychosis have become essential goals of psychiatry. However, clinical impressions are insufficient for predicting psychosis outcomes in clinical high-risk (CHR) individuals; a more rigorous and objective model is needed. This study aims to develop and internally validate a model for predicting the transition to psychosis within 10 years.

METHODS

Two hundred and eight help-seeking individuals who fulfilled the CHR criteria were enrolled from the prospective, naturalistic cohort program for CHR at the Seoul Youth Clinic (SYC). The least absolute shrinkage and selection operator (LASSO)-penalized Cox regression was used to develop a predictive model for a psychotic transition. We performed k-means clustering and survival analysis to stratify the risk of psychosis.

RESULTS

The predictive model, which includes clinical and cognitive variables, identified the following six baseline variables as important predictors: 1-year percentage decrease in the Global Assessment of Functioning score, IQ, California Verbal Learning Test score, Strange Stories test score, and scores in two domains of the Social Functioning Scale. The predictive model showed a cross-validated Harrell's C-index of 0.78 and identified three subclusters with significantly different risk levels.

CONCLUSIONS

Overall, our predictive model showed a predictive ability and could facilitate a personalized therapeutic approach to different risks in high-risk individuals.

„Shifting the Curve“: Neue Entwicklungen und Herausforderungen im Bereich der Public Mental Health

In der nationalen und internationalen Forschung nimmt das noch relativ junge Fach der Public Mental Health einen immer wichtigeren Stellenwert ein. Allerdings bleibt eine zentrale Herausforderung, dieses Fach in seiner Interdisziplinarität abzubilden und den Diskurs im Spannungsfeld von Public Health, psychiatrischer Epidemiologie, psychischer Gesundheitsförderung, Prävention und Versorgungsforschung zu führen, um sein innovatives Potenzial vollständig auszuschöpfen. In diesem Spannungsfeld stellen sich eine Reihe von grundsätzlichen konzeptionellen und methodischen Fragen, die in diesem Essay unter Bezugnahme auf die Populationsstrategie von Geoffrey Rose exemplarisch auch hinsichtlich fundamentaler Ursachen von sozialen und gesundheitlichen Ungleichheiten erörtert und adressiert werden sollen, mit dem letztendlichen Ziel, die Grundlage zur Erfassung und Veränderung von psychischer Gesundheit auf Populationsebene zu verbessern.

Don't blame psychosis, blame the lack of services: a message for early intervention from the Greek standard care model

BACKGROUND

Early Intervention Services (EIS) aim to reduce relapse rates and achieve better treatment and functional outcomes for first episode psychosis (FEP) patients. Existing models of services in Greece are still treatment as usual (TAU), however a reform of mental health services is underway and initial steps have been taken to shift standard care towards EIS. The purpose of the study is to address therapeutic gaps by exploring service engagement and relapse rates in the current standard care model for psychosis.

METHODS

We examined follow-up and relapse rates one year after initial treatment contact in the first longitudinal FEP study conducted in Greece. 225 patients were enrolled between 2015-2020. Sociodemographic, clinical and functional characteristics were assessed in association with follow-up and relapse rates.

RESULTS

Within a TAU follow-up setting, one year attrition rates were high. Only 87 patients (38,7%) retained contact with services after one year and within this time frame, 19 of them (21,8%) experienced a severe relapse requiring rehospitalization. Demographic, clinical and functional contributors failed to predict service engagement and relapse rates, with the exception of treatment adherence.

CONCLUSION

Both follow-up and one-year rehospitalization rates in our FEP sample, highlight the need for the implementation of early intervention services, that will aim at engagement maximization and relapse prevention. These indexes also provide a benchmark against which future early intervention services for psychosis in Greece will have to demonstrate superior efficacy.

Too soon to discard Kraepelin: improving diagnosis by appropriate use of neo-Kraepelinian and unitary psychosis models

There is a debate in psychiatry regarding whether it is better to use neo-Kraepelinian diagnostic categories or unitary models of psychosis in clinical practice. This article argues that clinicians should use either model as appropriate for the case in question, along with the conceptual framework used in the clinical management of psychosis without a clear biological cause. It first explores the values involved in the development of psychiatric classification systems, the purpose of classification and how we reached the current DSM/ICD and unitary models of psychosis. It then describes a diagnostic approach in which the choice of model should depend on the case in question, and offers a diagnostic protocol to guide the decision.

Symptom dimensions stability over time in recent onset psychosis: A prospective study

BACKGROUND

The factorial structure of schizophrenia symptoms has been much debated but little is known on its degree of unicity, specificity as well as its dynamic over time. Symptom differentiation is a phenomenon according to which patients' symptoms could differentiate from one another during illness to form more independent, distinct dimensions. On the contrary, symptom dedifferentiation is an increase in the correlations between those symptoms over time. The goal of this study was to investigate symptom differentiation or dedifferentiation over time in recent onset psychosis using the Positive and Negative Syndrome Scale.

METHODS

A confirmatory factor analysis model based on the consensus five-factor model of the Positive and Negative Syndrome Scale for schizophrenia was estimated on seven different time points over a three-year period. A general factor capturing common variance between every symptom was also included. Explained common variance was computed for the general factor and each specific factor.

RESULTS

Three hundred and sixty-two recent onset psychosis patients were assessed. Results showed no evidence for either symptom differentiation or dedifferentiation over time. Specific symptoms accounted for >70 % of the variance suggesting a high degree of specificity of the symptomatology.

CONCLUSIONS

Overall, this study adds support for a highly multidimensional approach to clinical symptom assessment with an explicit focus on depression. The premise behind the staging approach being inherently one-dimensional, implications for further research is discussed.

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.

Anxiety symptoms, rule learning, and cognitive flexibility in non-clinical psychosis

Individuals with psychotic-like experiences (PLEs) represent a critical group for improving the understanding of vulnerability factors across the psychosis continuum. A growing body of literature has identified functional deficits associated with PLEs. However, it is unclear if such deficits purely reveal the underlying psychosis vulnerability or if they are also linked with comorbid anxiety symptoms. Although anxiety disorders are often associated with impairments in psychosis-risk, symptoms of anxiety may facilitate executive functioning in certain psychosis groups. The Community Assessment of Psychic Experiences was completed to assess psychosis-like symptoms in a total of 57 individuals, and its median score was used to categorize PLE groups (high-PLE = 24, low-PLE = 33). Anxiety symptoms were measured via the Beck Anxiety Inventory, and cognitive flexibility was measured by the Penn Conditional Exclusion Test. The high-PLE group endorsed more anxiety symptoms, demonstrated poorer accuracy and efficiency on the cognitive task, and made more perseverative errors compared to the low-PLE group. Within the high-PLE group, higher levels of anxiety symptoms were associated with better performance and less perseverative errors compared to individuals with lower levels of anxiety symptoms. Conversely, greater anxiety symptoms were associated with poorer performance in the low-PLE group. Taken together, these findings provide a preliminary support for a potential psychosis vulnerability × anxiety symptom interaction. Given the interest in the psychosis continuum and potential treatment implications, the present findings warrant replication efforts.

Psychiatric hospital experiences that support and frustrate emerging adults' psychological needs: A self-determination theory perspective

AIM

There are international efforts to implement developmentally appropriate and youth-oriented mental health services for emerging adults to increase treatment engagement and the success of early intervention. While significant progress has been made in developing community service models, limited research has focused on how to design psychiatric inpatient settings that promote the recovery of emerging adults. The present study attempts to address this knowledge gap through a qualitative exploration of hospital experiences that influence psychological need satisfaction and frustration, as defined by self-determination theory (SDT).

METHODS

Inpatients (N = 104) from an emerging adult psychiatry unit were interviewed regarding hospital experiences that related to satisfaction or frustration of SDT needs for autonomy, competence, and relatedness.

RESULTS

A basic interpretative qualitative analysis highlighted six key aspects of the hospital experience relevant to these needs: (a) social interactions, (b) freedom of behaviour and access, (c) programs and activities, (d) treatment collaboration and choice, (e) restraining/unpleasant hospital practices, and (f) progress, symptoms, and functioning. The findings support SDT's emphasis on the importance of autonomy support, structure, and involvement for need satisfaction.

CONCLUSIONS

The study sheds light on aspects of the hospital milieu that may be essential to recovery-oriented inpatient care and on experiences that may be distinctly important for emerging adults, such as support for independence and the opportunity to relate to same-age co-patients experiencing similar mental health problems and life circumstances.
