Symptomatic and functional remission in patients with first-episode psychosis

Measures of Social and Occupational Function in Early Psychosis: A Systematic Review and Meta-analysis

Deficits in social and occupational function are widely reported in psychosis, yet no one measure of function is currently agreed upon as a gold standard in psychosis research. The aim of this study was to carry out a systematic review and meta-analysis of functioning measures to determine what measures were associated with largest effect sizes when measuring between-group differences, changes over time, or response to treatment. Literature searches were conducted based on PsycINFO and PubMed to identify studies for inclusion. Cross-sectional and longitudinal observational and intervention studies of early psychosis (≤5 years since diagnosis) that included social and occupational functioning as an outcome measure were considered. A series of meta-analyses were conducted to determine effect size differences for between-group differences, changes over time, or response to treatment. Subgroup analyses and meta-regression were carried out to account for variability in study and participant characteristics. One hundred and sixteen studies were included, 46 studies provided data (N = 13 261) relevant to our meta-analysis. Smallest effect sizes for changes in function over time and in response to treatment were observed for global measures, while more specific measures of social and occupational function showed the largest effect sizes. Differences in effect sizes between functioning measures remained significant after variability in study and participant characteristics were accounted for. Findings suggest that more specific measures of social function are better able to detect changes in function over time and in response to treatment.

Effects of yoga on clinical symptoms, quality of life and social functioning in patients with schizophrenia: A systematic review and meta-analysis

BACKGROUND

Yoga is gradually being explored as a potential complementary intervention in addition to psychiatric drugs for schizophrenia. However, there are conflicts on the efficacy of yoga for schizophrenia. This meta-analysis was aimed to evaluate the association of yoga intervention with reductions on clinical symptoms and improvements in quality of life (QoL) as well as social functioning among schizophrenia.

METHOD

Systematic literature search was undertaken to identify all RCTs that compared yoga with active or passive controls for patients with schizophrenia from inception to July 2023. The outcomes were measurements of positive symptoms, negative symptoms, QoL and social functioning. Random-effects models were performed to calculate the effect sizes in the standardized mean differences reporting as Hedges' s g statistic.

RESULTS

19 studies enrolling 1274 participants with schizophrenia were included. Yoga had a medium effect on positive symptoms in the short term (Hedges's g = 0.31) and small effect in the long term (Hedges's g = 0.18). Medium significant effects were also found on negative symptoms in both the short term (Hedges's g = 0.44) and the long term (Hedges's g = 0.35). Yoga had a significant impact on improving both total QoL (Hedges's g = 0.34) and social functioning (Hedges's g = 0.45) with medium effect sizes.

CONCLUSIONS

Yoga was associated with significant reductions on negative and positive symptoms, and significant improvements in QoL as well as social functioning in patients with schizophrenia. Future research should explore the long-term efficacy of yoga for schizophrenia, encompassing more diverse populations.

Combining transcranial magnetic stimulation with training to improve social cognition impairment in schizophrenia: a pilot randomized controlled trial

Schizophrenia is a severe, chronic mental disorder that profoundly impacts patients' everyday lives. The illness's core features include positive and negative symptoms and cognitive impairments. In particular, deficits in the social cognition domain showed a tighter connection to patients' everyday functioning than the other symptoms. Social remediation interventions have been developed, providing heterogeneous results considering the possibility of generalizing the acquired improvements in patients' daily activities. In this pilot randomized controlled trial, we investigated the feasibility of combining fifteen daily cognitive and social training sessions with non-invasive brain stimulation to boost the effectiveness of the two interventions. We delivered intermittent theta burst stimulation (iTBS) over the left dorsolateral prefrontal cortex (DLPFC). Twenty-one patients were randomized into four groups, varying for the assigned stimulation condition (real vs. sham iTBS) and the type of cognitive intervention (training vs. no training). Clinical symptoms and social cognition tests were administered at five time points, i.e., before and after the treatment, and at three follow-ups at one, three, and six months after the treatments' end. Preliminary data show a trend in improving the competence in managing emotion in participants performing the training. Conversely, no differences were found in pre and post-treatment scores for emotion recognition, theory of mind, and attribution of intentions scores. The iTBS intervention did not induce additional effects on individuals' performance. The methodological approach's novelty and limitations of the present study are discussed.

The association between clinical, sociodemographic, familial, and environmental factors and treatment resistance in schizophrenia: A machine-learning-based approach

BACKGROUND

Prediction of treatment resistance in schizophrenia (TRS) would be helpful to reduce the duration of ineffective treatment and avoid delays in clozapine initiation. We applied machine learning to identify clinical, sociodemographic, familial, and environmental variables that are associated with TRS and could potentially predict TRS in the future.

STUDY DESIGN

Baseline and follow-up data on trait(-like) variables from the Genetic Risk and Outcome of Psychosis (GROUP) study were used. For the main analysis, we selected patients with non-affective psychotic disorders who met TRS (n = 200) or antipsychotic-responsive criteria (n = 423) throughout the study. For a sensitivity analysis, we only selected patients who met TRS (n = 76) or antipsychotic-responsive criteria (n = 123) at follow-up but not at baseline. Random forest models were trained to predict TRS in both datasets. SHapley Additive exPlanation values were used to examine the variables' contributions to the prediction.

STUDY RESULTS

Premorbid functioning, age at onset, and educational degree were most consistently associated with TRS across both analyses. Marital status, current household, intelligence quotient, number of moves, and family loading score for substance abuse also consistently contributed to the prediction of TRS in the main or sensitivity analysis. The diagnostic performance of our models was modest (area under the curve: 0.66-0.69).

CONCLUSIONS

We demonstrate that various clinical, sociodemographic, familial, and environmental variables are associated with TRS. Our models only showed modest performance in predicting TRS. Prospective large multi-centre studies are needed to validate our findings and investigate whether the model's performance can be improved by adding data from different modalities.

Hospitalisation outcomes for patients with severe mental illness treated by female vs. male psychiatry residents

OBJECTIVE

Recent literature suggests that female physicians provide higher quality of care compared to their male counterparts across a variety of physical medical conditions. We examine whether a similar phenomenon is observed for psychiatry residents treating hospitalised psychiatric patients.

METHODS

We analysed 300 hospitalised patient records from Shalvata Mental Healthcare Centre (Hod Hasharon, Israel). Resident-patient sex matchings were compared.

RESULTS

No significant differences were observed in terms of residents' age and patients' age, medical condition and hospitalisation history. Male and female patients treated by female residents presented shorter hospitalisations (58 and 54 days compared to 67 and 66 days, respectively, p < .05), longer time to next hospitalisation (269 and 179 days compared to 179 and 123 days, respectively, p < .01), lower 30-day readmission rate (37% and 35% compared to 10% and 19%, respectively, p < .05), higher levels of family involvement during hospitalisation (2.6 and 2.7 points compared to 2.1 and 1.9 points, respectively, p < .01) and higher chances of obtaining rehabilitation services (39% and 34% vs. 23% and 17%, respectively, p < .05).

CONCLUSIONS

Hospitalised patients treated by female psychiatry residents are associated with better hospitalisation outcomes compared to those cared for by male residents. KEY POINTSBoth male and female patients treated by female residents presented better hospitalisation outcomes.These hospitalisation outcomes include shorter hospitalisation periods, longer time to next hospitalisation, lower 30-day remission rate, significantly higher levels of family involvement and higher chances of obtaining rehabilitation services.Further work is needed in order to investigate the sources and reasons for the identified differences.

Cognitive subgroups and the relationships with symptoms, psychosocial functioning and quality of life in first-episode non-affective psychosis: a cluster-analysis approach

Introduction

Prior research examining cognitive heterogeneity in psychotic disorders primarily focused on chronic schizophrenia, with limited data on first-episode psychosis (FEP). We aimed to identify distinct cognitive subgroups in adult FEP patients using data-driven cluster-analytic approach, and examine relationships between cognitive subgroups and a comprehensive array of illness-related variables.

Methods

Two-hundred-eighty-nine Chinese patients aged 26-55 years presenting with FEP to an early intervention program in Hong Kong were recruited. Assessments encompassing premorbid adjustment, illness-onset profile, symptom severity, psychosocial functioning, subjective quality-of-life, and a battery of cognitive tests were conducted. Hierarchical cluster-analysis was employed, optimized with k-means clustering and internally-validated by discriminant-functional analysis. Cognitive subgroup comparisons in illness-related variables, followed by multivariable multinominal-regression analyzes were performed to identify factors independently predictive of cluster membership.

Results

Three clusters were identified including patients with globally-impaired (n = 101, 34.9%), intermediately-impaired (n = 112, 38.8%) and relatively-intact (n = 76, 26.3%) cognition (GIC, IIC and RIC subgroups) compared to demographically-matched healthy-controls' performance (n = 50). GIC-subgroup was older, had lower educational attainment, greater positive, negative and disorganization symptom severity, poorer insight and quality-of-life than IIC- and RIC-subgroups, and higher antipsychotic-dose than RIC-subgroup. IIC-subgroup had lower education levels and more severe negative symptoms than RIC-subgroup, which had better psychosocial functioning than two cognitively-impaired subgroups. Educational attainment and disorganization symptoms were found to independently predict cluster membership.

Discussion

Our results affirmed cognitive heterogeneity in FEP and identified three subgroups, which were differentially associated with demographic and illness-related variables. Further research should clarify longitudinal relationships of cognitive subgroups with clinical and functional outcomes in FEP.

Psychosis brain subtypes validated in first-episode cohorts and related to illness remission: results from the PHENOM consortium

Using machine learning, we recently decomposed the neuroanatomical heterogeneity of established schizophrenia to discover two volumetric subgroups-a 'lower brain volume' subgroup (SG1) and an 'higher striatal volume' subgroup (SG2) with otherwise normal brain structure. In this study, we investigated whether the MRI signatures of these subgroups were also already present at the time of the first-episode of psychosis (FEP) and whether they were related to clinical presentation and clinical remission over 1-, 3-, and 5-years. We included 572 FEP and 424 healthy controls (HC) from 4 sites (Sao Paulo, Santander, London, Melbourne) of the PHENOM consortium. Our prior MRI subgrouping models (671 participants; USA, Germany, and China) were applied to both FEP and HC. Participants were assigned into 1 of 4 categories: subgroup 1 (SG1), subgroup 2 (SG2), no subgroup membership ('None'), and mixed SG1 + SG2 subgroups ('Mixed'). Voxel-wise analyses characterized SG1 and SG2 subgroups. Supervised machine learning analyses characterized baseline and remission signatures related to SG1 and SG2 membership. The two dominant patterns of 'lower brain volume' in SG1 and 'higher striatal volume' (with otherwise normal neuromorphology) in SG2 were identified already at the first episode of psychosis. SG1 had a significantly higher proportion of FEP (32%) vs. HC (19%) than SG2 (FEP, 21%; HC, 23%). Clinical multivariate signatures separated the SG1 and SG2 subgroups (balanced accuracy = 64%; p < 0.0001), with SG2 showing higher education but also greater positive psychosis symptoms at first presentation, and an association with symptom remission at 1-year, 5-year, and when timepoints were combined. Neuromorphological subtypes of schizophrenia are already evident at illness onset, separated by distinct clinical presentations, and differentially associated with subsequent remission. These results suggest that the subgroups may be underlying risk phenotypes that could be targeted in future treatment trials and are critical to consider when interpreting neuroimaging literature.

Association between exposome score for schizophrenia and functioning in first-episode psychosis: results from the Athens first-episode psychosis research study

BACKGROUND

Evidence suggests that environmental factors not only increase psychosis liability but also influence the prognosis and outcomes of psychotic disorders. We investigated temporal and cross-sectional associations of a weighted score of cumulative environmental liability for schizophrenia - the exposome score for schizophrenia (ES-SCZ) - with functioning in first-episode psychosis (FEP).

METHODS

Data were derived from the baseline and 1-month assessments of the Athens FEP Research Study that enrolled 225 individuals with FEP. The Global Assessment of Functioning (GAF) and the Personal and Social Performance Scale (PSP) were used to measure social, occupational, and psychological functioning. The ES-SCZ was calculated based on the previously validated method.

RESULTS

ES-SCZ was associated with the total scores of GAF and PSP at baseline and 1-month assessments. These findings remained significant when accounting for several associated alternative explanatory variables, including other environmental factors (obstetric complications, migration, ethnic minority), clinical characteristics (duration of untreated psychosis, symptom severity, previous antipsychotic use), and family history of psychosis, demonstrating that the association between ES-SCZ and functioning is over and above other risk factors and cannot be explained by symptom severity alone. Functioning improved from baseline to 1-month assessment, but no significant ES-SCZ-by-time interaction was found on functioning, indicating that functioning changes were not contingent on ES-SCZ.

CONCLUSIONS

Our findings suggest that rather than a predictor of functional improvement, ES-SCZ represents a stable severity indicator that captures poor functioning in early psychosis. Environmental risk loading for schizophrenia (ES-SCZ) can be beneficial for clinical characterization and incorporated into transdiagnostic staging models.

The relevance of processing speed in the functioning of people with first-episode psychosis

Deficits in functioning affect people with first-episode psychosis. Deficits in cognitive performance are common in such individuals and appear to be related to functioning. The present study examined the relationship between the domains of cognitive performance and personal and social functioning, as well as evaluating which cognitive domains are the most closely related to personal and social functioning and whether they explain variations once other clinical and sociodemographic aspects are accounted for. Ninety-four people with first-episode psychosis participated in the study; they were assessed with the MATRICS battery. Symptoms were evaluated with the Emsley factors of the positive and negative syndrome scale. Cannabis use, duration of untreated psychosis, suicide risk, perceived stress, antipsychotic doses, and premorbid intelligence quotient was accounted for. Processing speed, attention/vigilance, working memory, visual learning, reasoning and problem solving correlated to personal and social functioning. Processing speed emerged as the strongest predictor of social and personal functioning and underscores the importance of targeting this domain in treatment. Moreover, suicide risk and excited symptoms were also significant variables in functioning. Early intervention, focusing on improvement of processing speed, may be crucial to the improvement of functioning in first-episode psychosis. The relationship of this cognitive domain with functioning in first-episode psychosis should be studied further.

Evaluation of cognitive insight, social functionality, and coping attitudes of patients diagnosed with schizophrenia being followed-up in a community mental health center

AIM

This study was conducted to evaluate the cognitive insight, social functionality, and coping attitudes of patients diagnosed with schizophrenia being followed-up in a Community Mental Health Center (CMHC).

DESIGN AND METHODS

The population of this descriptive and relationship-seeking study comprised 170 schizophrenia patients followed-up in the CMHC. Study data were collected using the Information Form, the Beck Cognitive Insight Scale (BCIS), the Social Functioning Assessment Scale (SFAS), and the Coping Orientation of Problem Experience (COPE).

FINDINGS

A moderately significant positive correlation between cognitive insight and social functionality was determined. It was found that participants with high cognitive insight and social functionality used more problem- and emotion-focused coping methods.

APPLICATION IMPLICATIONS

It is thought that practices that improve cognitive insight and social functionality will contribute to the rehabilitation of patients with schizophrenia by supporting their coping skills.

Predictors of full recovery in patients with early stage schizophrenia spectrum disorders

To promote recovery in psychosis, targeting modifiable factors related to recovery is critical. Using more strict definition of full recovery, we examined predictors for recovery in patients with early stage schizophrenia spectrum disorders (SSD) followed up to 6.5 years. The target subjects were 375 patients with early stage SSD who had been over at least 1-year after registration and evaluated. The criteria for full recovery were having the score of the Positive and Negative Syndrome Scale (PANSS) 8-item ≤ 2 and adequate functional recovery for at least 1-year. We performed univariate Cox and stepwise Cox regression in both total and acute patients. In stepwise Cox regression, several independent predictors for recovery, i.e., negative symptoms of the PANSS, duration of untreated psychosis (DUP) and non-professional job were identified in patients with early stage SSD. In acute patients, other factors such as professional job and subjective well-being under neuroleptics were more important. The present study identified independent predictors for recovery modifiable by various psychosocial intervention and early intervention services. Moreover, it highlights the need of providing different treatment strategies depending on clinical status.

Three-year outcomes and predictors for full recovery in patients with early-stage psychosis

In the present study, various outcomes over 3-year period in patients with early stage psychosis including remission, recovery, relapse and medication adherence were investigated. Predictor for full recovery at year 3 was also examined. Three-year follow-up data in 534 patients with schizophrenia spectrum disorders (SSD) and psychotic disorder not otherwise specified (PNOS) were examined for overall outcome trajectories. The data of completers at year 3 (n = 157) were used to identify predictors for recovery using logistic regression. The rates of symptomatic remission and full recovery at 6-, 12-, 24-, and 36-month follow-up were 76.10, 69.20, 79.50, and 79.10%, and 22.80, 26.40, 28.60, and 39.60%, respectively. The rates of drop-out and relapse at 6-, 12-, 24-, and 36-month follow-up were 25.4, 29.5, 38.6, and 51.1%, and 3.7, 8.9, 19.0, and 38.9%, respectively. The rates of good adherence and prescription of Long-Acting Injectable Antipsychotics (LAIA) at 6-, 12-, 24- and 36-month follow-up were 87.8, 88.0, 91.9, and 93.9%, and 18.3, 21.7, 22.0, and 25.5%, respectively. Significant predictors for full recovery were duration of untreated psychosis (DUP), family intimacy and physical activity. We observed similar or better results on remission, recovery, and relapse rates compared to other previous studies. Effective psychosocial intervention should be provided to shorten the gap between remission and recovery rates and to address DUP, family issues, and exercise to enhance recovery.

Symptomatic and full remission rates in first-episode psychosis: A 12-month follow-up study in Korea

AIM

In the present study, the prevalence and predictors of symptomatic and full remission were investigated in patients with first-episode psychosis (FEP) at the 12-month follow-up.

METHODS

A total of 308 participants aged 18-45 years fulfilled the study inclusion criteria and 214 completed the 12-month follow-up.

RESULTS

At the 12-month follow-up, 67.3% (142) and 25.9% (55) of the FEP patients met the criteria for symptomatic and full remission, respectively. Stepwise logistic regression analysis showed a shorter duration of untreated psychosis (DUP), no family history, lower Positive and Negative Syndrome Scale (PANSS) negative symptom scores at baseline and higher familial support predicted symptomatic remission at the 12-month follow-up. A higher educational level, shorter DUP, lower PANSS general symptoms scores at baseline and higher subjective well-being under neuroleptics emotional regulation scores predicted full remission.

CONCLUSIONS

Our findings regarding the rates of symptomatic and full remission are consistent with previous studies. The results indicate a large discrepancy between symptomatic versus full remission rates at a 12-month follow-up in patients with FEP. Effective psychosocial interventions are necessary to improve the outcomes of FEP patients.

Is the effect of cognitive reserve in longitudinal outcomes in first-episode psychoses dependent on the use of cannabis?

BACKGROUND

Cognitive reserve (CR) is a protective factor against cognitive and functional impairment in first-episode psychosis (FEP). The aim of this study was to evaluate the differences in clinical presentation according to the use of cannabis (cannabis users vs non-users) among patients presenting a FEP (non-affective vs affective psychosis), to investigate the impact of CR and cannabis use on several outcomes and to explore the potentially mediatory role played by CR in the relationship between cognitive domains or clinical status and functionality, depending on the use of cannabis.

METHODS

Linear regression analysis models were carried out to assess the predictive value of CR on clinical, functional and cognitive variables at baseline and at two-year follow-up. The mediation analyzes were performed according to the principles of Baron and Kenny.

RESULTS

CR was associated with better cognitive performance, regardless of cannabis consumption or diagnosis. In both diagnoses, CR was associated with better clinical and functional outcomes in those patients who did not use cannabis. In terms of mediation procedure, CR mediates the relationship between some cognitive domains and functioning at follow-up only in patients without cannabis use.

LIMITATIONS

The small sample size of the affective group.

CONCLUSIONS

CR plays a differential role in the outcome of psychoses according to whether patients are cannabis users or not. Both in affective and non-affective groups CR exerted a greater effect in patients without cannabis use. Our results suggest that the deleterious effect of cannabis use on functioning in FEP surpasses the protective effect of CR.

Associations of living arrangements with symptoms and functioning in schizophrenia

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Effects of Adherence to Pharmacological Treatment on the Recovery of Patients with Schizophrenia

The aim of this study was to evaluate the effects of adherence to antipsychotic treatment on the recovery of patients with schizophrenia in northern Chile. One hundred and fifty-one patients diagnosed with schizophrenia completed the Drug Attitude Inventory (DAI-10), Positive and Negative Syndrome Scale for Schizophrenia (PANSS), Recovery Assessment Scale (RAS-24), sociodemographic information, and clinical and treatment characteristics of patients with schizophrenia. Multivariate analysis with multiple linear regression was then performed to identify variables that were potentially associated with the recovery assessment (variable criterion). A significant association was found between adherence to antipsychotic medication and the Willing to Ask for Help dimension of Recovery (β = 0.239, p = 0.005). Association of clinical and socio-demographic variables with recovery were identified: negative symptoms with Personal Confidence and Hope (β = -0.341, p = 0.001) and Goal and Success Orientation (β = -0.266, p = 0.014); cognitive symptoms with Willing to Ask for Help (β = -0.305, p = 0.018) and no domination by symptoms (β = -0.351, p = 0.005); marital status with reliance on others (β = -0.181, p = 0.045); age with Personal Confidence and Hope (β = -0.217, p = 0.021), Goal and Success Orientation (β = -0.296, p = 0.003), and no domination by symptoms (β = 0.214, p = 0.025). Adherence has a positive relationship with personal recovery in this sample of Chilean patients with schizophrenia.

Are patients improving during and after a psychiatric hospitalisation? Continuity of care outcomes of compulsory and voluntary admissions to an Italian psychiatric ward

Background: To compare the characteristics of compulsory admissions (CAs) and voluntary admissions (VAs) in a General Hospital Psychiatric Unit (GHPU), and to assess whether CA and VA patients’ outcomes improved during hospitalisation and followup in mental health services (MHS) based on community continuity of care.

Design and methods: Observational longitudinal study comparing 19 CAs and 83 VAs consecutively admitted to GHPU of Udine, Italy, and followed-up for six-months by MHS. Five psychometric scales assessed psychosocial and clinical characteristics for each patient at admission (T0), discharge (T1) and follow-up (T2). Statistical analyses were performed using: multivariate logistic regression for comparing CA and VA; Friedman χ2 and Mann-Whitney tests for outcomes’ improvement.

Results: Being hospitalised for a psychotic crisis was the most significant predictor of CA (OR = 5.07). An outcomes’ improvement was observed from T0 to T1 in almost all psychometric tests, while from T1 to T2 only for PSP-A (useful social activities), CGI-S (severity of illness) and CGI-EI (drug’s efficacy related to side effects). CA was associated to lower performances in all scales at T0, in GAF and CGI-S at T1, while no difference with VA was observed at T2.

Conclusions: CA and VA patients improved to a same extent during hospitalisation and follow-up, particularly in relation to social functioning. This fosters the hypothesis that communitybased MHS using a longitudinal continuity of care model might achieve recovery in a long-term perspective. Future research may benefit by considering patients’ subjective experiences and assessing long-term improvement in those who received personcentred interventions.

Autistic traits in first-episode psychosis: Rates and association with 1-year recovery outcomes

AIM

There is a growing appreciation that subthreshold but clinically elevated levels of autistic traits are clinically relevant. This study examined autistic traits in Singaporean patients with first-episode psychosis and their association with 1-year psychosis recovery.

METHODS

The relationship between baseline patient characteristics, autistic traits (measured with autism screening questionnaires) and psychosis recovery outcomes at 1-year were examined in 180 adults in the Early Intervention Psychosis Programme in Singapore.

RESULTS

Out of 180 participants, 50 (27.8%) had clinically elevated above screening-cut off levels of autistic traits on the self-reported 10-item Autism Spectrum Quotient and 8 (4.4%) on the staff-rated Autism Spectrum Disorder in Adults Screening Questionnaire. At baseline, those with more autistic traits were more likely to be unemployed, economically inactive (ie, students or homemakers); and to have diagnoses of mood disorder with psychotic features, brief psychotic disorder or psychotic disorder not otherwise specified as compared to schizophrenia spectrum and delusional disorder diagnoses. Although most participants showed improvements in their clinical outcomes at 1-year, those with higher autistic traits improved less in the Positive and Negative Syndrome Scale general psychopathology scale and in Global Assessment of Functioning symptomatology.

CONCLUSIONS

Autistic traits are common in those with first-episode psychosis and may be associated with poorer clinical outcomes. Validated screening tools should be developed in this population to support earlier reporting.

Narrative identity in the psychosis spectrum: A systematic review and developmental model

Individuals with schizophrenia-spectrum disorders face profound challenges as they attempt to maintain identity through the course of illness. Narrative identity-the study of internalized, evolving life stories-provides a rich theoretical and empirical perspective on these challenges. Based on evidence from a systematic review of narrative identity in the psychosis spectrum (30 studies, combined N = 3859), we argue that the narrative identities of individuals with schizophrenia-spectrum disorders are distinguished by three features: disjointed structure, a focus on suffering, and detached narration. Psychotic disorders typically begin to emerge during adolescence and emerging adulthood, which are formative developmental stages for narrative identity, so it is particularly informative to understand identity disturbances from a developmental perspective. We propose a developmental model in which a focus on suffering emerges in childhood; disjointed structure emerges in middle and late adolescence; and detached narration emerges before or around the time of a first psychotic episode. Further research with imminent risk and early course psychosis populations would be needed to test these predictions. The disrupted life stories of individuals on the psychosis spectrum provide multiple rich avenues for further research to understand narrative self-disturbances.

First-episode psychosis: How long does it last? A review of evolution and trajectory

Study of first-episode psychosis (FEP), an episode of psychotic nature which manifests for the first time in an individual in the longitudinal continuum of his/her illness, has been study matter of research interest in recent years. A comprehensive review of the literature will help us understand the evolution and trajectory of this concept better. A literature review of available articles addressing the concept, phenomenology, evolution, identification, course, and outcome of FEP was done; the same was subsequently divided into broad topics for better clarity and analyzed. FEP constituted a clinical psychotic phenomenon with underlying significant heterogeneity in diagnosis, stability, course, and outcome. The study has attempted to view FEP both as horizontal spectrum across various diagnoses and longitudinally ranging from asymptomatic individual with unknown risk status to attenuated psychosis to multiple relapses/unremitting illness. Many risk and protective factors have been brought out with varying certainty ranging bio-psycho-social spectrum. Efforts have been made to calculate polygenic risk score based on genes involvement/sharing between various psychotic spectrum disorders; as well as biomarker panels to identify people at risk. FEP may prove to be an important concept to understand psychosis in general; without putting things into the diagnostic rubric. It may help understand multiple risk and protective factors for the course and outcome of psychotic illness and may clear the cloud to sharpen the evidence toward commonality and distinctiveness between various psychotic diagnoses in vogue for more comprehensive concept.

The Role of Premorbid IQ and Age of Onset as Useful Predictors of Clinical, Functional Outcomes, and Recovery of Individuals with a First Episode of Psychosis

BACKGROUND

premorbid IQ (pIQ) and age of onset are predictors of clinical severity and long-term functioning after a first episode of psychosis. However, the additive influence of these variables on clinical, functional, and recovery rates outcomes is largely unknown.

METHODS

we characterized 255 individuals who have experienced a first episode of psychosis in four a priori defined subgroups based on pIQ (low pIQ < 85; average pIQ ≥ 85) and age of onset (early onset < 18 years; adult onset ≥ 18 years). We conducted clinical and functional assessments at baseline and at two-year follow-up. We calculated symptom remission and recovery rates using the Positive and Negative Symptoms of Schizophrenia Schedule (PANSS) and the Global Assessment Functioning (GAF or Children-GAF). We examined clinical and functional changes with pair-wise comparisons and two-way mixed ANOVA. We built hierarchical lineal and logistic regression models to estimate the predictive value of the independent variables over functioning or recovery rates.

RESULTS

early-onset patients had more severe positive symptoms and poorer functioning than adult-onset patients. At two-year follow-up, only early-onset with low pIQ and adult-onset with average pIQ subgroups differed consistently, with the former having more negative symptoms (d = 0.59), poorer functioning (d = 0.82), lower remission (61% vs. 81.1%), and clinical recovery (34.1% vs. 62.2%).

CONCLUSIONS

early-onset individuals with low pIQ may present persistent negative symptoms, lower functioning, and less recovery likelihood at two-year follow-up. Intensive cognitive and functional programs for these individuals merit testing to improve long-term recovery rates in this subgroup.

Altered risky decision making in patients with early non-affective psychosis

Abnormal risky decision making may represent an important factor contributing to functional impairment in psychotic disorders. Previous research revealed impaired decision making under risk in patients with chronic schizophrenia. However, risky decision making is under-studied in the early course of illness. We examined risky decision making in 33 patients with early non-affective psychosis and 32 demographically matched controls, using two well-validated experimental paradigms, balloon analogue risk task (BART) and Risky-Gains task (RGT), which modeled and assessed actual risk-taking behaviors in deliberative and time-pressured decision-making situations, respectively. Our results showed that patients exhibited suboptimal decision making on the BART and were more risk averse than controls by having fewer average balloon pumps in non-burst trials, lower explosion rate and lower total points gained. On the RGT, patients also behaved more conservatively than controls, with lower overall rate in choosing the risky option. Intriguingly, patients performed comparably to controls in adjusting risk-taking pattern following punished trials, suggesting relatively preserved sensitivity to punishment in early psychosis. Risk-taking measures showed no significant correlations with any symptom dimensions, impulsivity traits, cognitive functions or antipsychotic treatment after correcting for multiple comparisons. This study is the first to investigate risk-taking propensity in early psychosis based on BART/RGT performance, and consistently indicate that patients with early psychosis displayed altered risky decision making with increased risk aversion relative to healthy participants. Further investigation is warranted to clarify the longitudinal course of aberrant risky decision making and its relationship with functional outcome in early psychosis.

Childhood interpersonal trauma and premorbid social adjustment as predictors of symptom remission in first episode psychosis

BACKGROUND

Childhood interpersonal trauma (CIT) and premorbid adjustment are both associated with poor outcome in psychosis. In this study we investigate the relative impact of CIT and premorbid adjustment on symptom remission in first episode psychosis (FEP) over two years.

METHOD

A total of 232 participants with FEP were recruited through the early detection program of the The early detection and Intervention in Psychosis (TIPS)-2 study and followed up after two years. Symptom remission was according to consensus criteria. CIT was assessed with the semi-structured interview Freyd Goldberg Brief Betrayal Trauma Survey, and premorbid adjustment with the Premorbid Adjustment Scale. Generalized estimating equations and multivariate models were used to analyze the associations between remission, symptom levels over time, CIT and premorbid adjustment; and a path analysis of mediation effects of CIT through premorbid adjustment on remission.

RESULTS

In this sample with 57% males and a mean age of 26.6 years (SD 10.2), a third of participants had experienced CIT. The participants with CIT had poorer premorbid adjustment compared to those without. Statistical analyses found independent effects of CIT and an interaction effect of CIT with premorbid adjustment on remission after two years, suggesting that CIT moderates the effect of premorbid adjustment. However contrary to expectations, premorbid adjustment did not mediate the effect of CIT.

CONCLUSION

Our findings indicate a complex interplay between effects of interpersonal trauma and premorbid social adjustment on remission in psychosis. CIT appeared to moderate the effect of premorbid adjustment such that individuals with CIT and who had poor social functioning in childhood are at greater risk of non-remission. Findings indicate that better premorbid social relations could provide a buffer for the effects of trauma on symptom course.

Anxiety symptoms in first-episode psychosis

AIM

Anxiety disorders and symptoms are common in people with psychotic disorders, having a negative impact on clinical status, function level and overall prognosis. However, research on the significance of anxiety in predicting remission and long-term functioning in first-episode psychosis (FEP) is still scarce. This study investigated the effects of anxiety and obsessive-compulsive symptoms (OCS) on clinical and functional improvement in individuals with FEP.

METHODS

FEP patients (N = 97) aged 18-40 years were recruited from the University Hospital District of Helsinki and the City of Helsinki. Psychotic and anxiety symptoms were measured using the Brief Psychiatric Rating Scale. Obsessive-compulsive symptoms were assessed using the Obsessive-Compulsive Inventory (OCI-R), and functioning was evaluated using the Social and Occupational Functioning Assessment Scale (SOFAS). Follow-up measurements were performed at 2 and 12 months. We specifically studied whether anxiety and obsessive-compulsive symptoms at the 2-month follow-up assessment, at a time when the initial treatment response had been achieved, would predict outcomes at 12 months.

RESULTS

Symptoms of anxiety and OCS correlated moderately with each other and psychotic symptoms, but at the 12-month follow-up, OCS no longer correlated significantly with psychotic and anxiety symptoms. When the level of psychotic symptoms was adjusted for, more severe OCS at the 2-month follow-up was associated with a lower rate of remission at 12 months, whereas a higher level of anxiety symptoms at 2 months was associated with better functioning at 12 months.

CONCLUSIONS

OCS may be predictive of poorer clinical outcomes, whereas anxiety symptoms may predict better functional outcomes.

Schizophrenia outcomes in the 21st century: A systematic review

OBJECTIVE

We report a review of outcomes in schizophrenia in the twenty-first century, replicating and extending work undertaken by the late Richard Warner in his seminal book, "Recovery from Schizophrenia: Psychiatry and Political Economy" (1985;2004).

METHOD

Warner's methods were followed as closely as possible. Only observational/naturalistic studies were included. Six scientific databases were searched from 2000 to 2020. 6,640 records were retrieved. 47 met inclusion criteria.

RESULTS

Overall, complete recovery is higher in this study than in Warner's (37.75% cf 20.4%), especially for first episode psychosis (FEP) (57.1% cf 20.7%). Clinical recovery, annualized remission rate (ARR), and employment outcomes were significantly superior for first episode psychosis compared with multiple episode psychosis (MEP). ARR shows a trend toward reduction over time, from 2.2 before the financial crash of 2008 to 1.6 after (t = 1.85 df 40 p = .07). The decline is statistically significant for the MEP group (t = 2.32 df18 p = .03). There were no differences in outcome by region, sample characteristics, outcome measures used, or quality of studies. Heterogeneity of clinical outcome measures across the literature makes evidence synthesis difficult. Weak and inconsistent reporting of functional and employment outcomes mean that findings lack meaning with respect to lived experience.

CONCLUSION

Future research strategies should aim to reduce heterogeneity in clinical outcome measures and to increase the emphasis on capture and reporting of more sophisticated measures of social and functional outcome. Outcome domains should be disaggregated rather than conflated into unitary recovery constructs.

Structural Disadvantage and Culture, Race, and Ethnicity in Early Psychosis Services: International Provider Survey

OBJECTIVE

Little is known about provider perspectives on programmatic responses to structural disadvantage and cultural differences within early intervention in psychosis (EIP) services, programs, and models. The primary objective of this study was to investigate providers' perspectives on the impacts of disadvantage and minority race, ethnicity, and culture and to describe current practices and perceived gaps and concerns.

METHODS

An online survey of specialized EIP providers was disseminated in the United Kingdom, United States, Canada, Australia, and Chile. A total of 164 providers, representing 110 unique sites, completed the survey. Closed-ended questions gathered demographic and program data, including information on formal assessment of trauma or adversity, integration of trauma-informed care, integration of formal cultural assessment tools, training focused on culture, programmatic changes to address culture-related issues, and consultation with cultural insiders. Open-ended questions addressed the demographic mix of the program's client population; the perceived role and influence of trauma, structural disadvantage, and cultural differences; and concerns and needs related to these topics. Frequencies were examined for closed-ended items; open-ended responses were systematically coded.

RESULTS

Overall, survey findings suggested low levels of implementation of a variety of assessment and support practices related to cultural diversity in EIP programs. Coding of open-ended responses revealed numerous concerns regarding the impacts of disadvantage and cultural difference on clients and perceived gaps in policy and implementation.

CONCLUSIONS

An expansion of research and service development aimed at better meeting the disadvantage- and culture-related needs of young people with early psychosis and their families should be a priority for the field.

An Observational Cohort of First Episode Psychosis in Iran: The Azeri Recent Onset Acute Phase Psychosis Survey (ARAS Cohort) Study Protocol

Background: Most of our knowledge about the etiology, course, treatment, and outcome of schizophrenia spectrum and other psychotic disorders stems from Western countries. Data from populations living in other geographical areas and low- and middle-income countries, with different genomes (ethnicity) and exposomes (e.g., culture and social support, drugs of abuse, religion), will add to our knowledge of this complex disorder. Methods: The Azeri Acute phase/Recent onset psychosis Survey (ARAS) has been initiated to study the course of the disorder in patients with recent-onset psychosis using validated diagnostic tools and a comprehensive outcome monitoring system, aiming to reveal indicators for understanding the risk and resilience factors and for choosing the best-personalized treatment strategy. All participants will be evaluated for clinical signs and symptoms as well as risk and resilience factors and will be followed up for 1, 3, and 5 years for outcomes in several domains. A hierarchical cluster method will be applied to identify the number of clusters for each outcome. Defined models will be applied to assess the predictive value of cognition on symptomatic and functional outcomes at follow-up. Discussion: The ARAS cohort will yield significant academic- (research and education) and care-related achievements. ARAS data and experience will have value both in being a useful model for other parts of this region and in an expansion of the currently available knowledge.

General Functioning in Patients With First-Episode Psychosis After the First 18 Months of Treatment

BACKGROUND

One of the main goals in the treatment of first-episode psychosis (FEP) is achieving functional remission. This study aims to analyze whether initial neurocognitive status and the use of specific pharmacological and psychosocial treatment options in FEP can predict general functioning after 18 months of treatment.

METHODS

We conducted a longitudinal naturalistic study with a sample of 129 patients with FEP treated at 2 Croatian psychiatric clinics from 2016until 2018. Ordinal regression was used to predict the global level of functioning assessed with the Global Assessment of Functioning scale (GAF) at the 18th month of treatment from the baseline symptoms (assessed with a set of neurocognitive tests) and different treatment options.

RESULTS

Higher score on GAF at the 18th month was significantly predicted by female sex, better baseline verbal memory and GAF scores, and the type of treatment. Group multimodal psychosocial treatment, antipsychotic polytherapy, and not being treated with sedatives at baseline predicted better GAF scores at follow-up. In the exploratory analysis, taking sedatives in the final assessment and being rehospitalized due to relapse predicted worse GAF scores at the end of follow-up.

CONCLUSIONS

Although baseline neurocognitive features and baseline general functioning seem to influence the overall long-term functioning of persons with FEP, addition of a multimodal group psychosocial treatment program and appropriate medication seem to be equally important for improving the patients' level of functioning after the FEP.

Does Yoga Have a Role in Schizophrenia Management?

PURPOSE OF REVIEW

To review the efficacy of add-on yoga therapy in improving symptoms of schizophrenia and quality of life and examine the possible underlying biological mechanisms of yoga in schizophrenia.

RECENT FINDINGS

Quality of life, cognitive symptoms, and negative symptoms have been found to improve with add-on yoga therapy in schizophrenia (pooled mean effect size 0.8, 0.6, and 0.4, respectively). Yoga also seems to have a small effect on improving positive symptoms. Less explored areas include adverse effects of yoga itself as well as its effects on antipsychotic-induced complications. Preliminary findings suggest that the effects of yoga may be mediated by neurohormonal mechanisms and functional changes in brain activity. Add-on yoga therapy is a potential treatment option for improving quality of life, cognitive symptoms, and negative symptoms in schizophrenia. Future studies should explore efficacy in multicentric trials as well as possible neurobiological changes underlying the effects.

Abnormal cognitive effort allocation and its association with amotivation in first-episode psychosis

BACKGROUND

Abnormal effort-based decision-making represents a potential mechanism underlying motivational deficits (amotivation) in psychotic disorders. Previous research identified effort allocation impairment in chronic schizophrenia and focused mostly on physical effort modality. No study has investigated cognitive effort allocation in first-episode psychosis (FEP).

METHOD

Cognitive effort allocation was examined in 40 FEP patients and 44 demographically-matched healthy controls, using Cognitive Effort-Discounting (COGED) paradigm which quantified participants' willingness to expend cognitive effort in terms of explicit, continuous discounting of monetary rewards based on parametrically-varied cognitive demands (levels N of N-back task). Relationship between reward-discounting and amotivation was investigated. Group differences in reward-magnitude and effort-cost sensitivity, and differential associations of these sensitivity indices with amotivation were explored.

RESULTS

Patients displayed significantly greater reward-discounting than controls. In particular, such discounting was most pronounced in patients with high levels of amotivation even when N-back performance and reward base amount were taken into consideration. Moreover, patients exhibited reduced reward-benefit sensitivity and effort-cost sensitivity relative to controls, and that decreased sensitivity to reward-benefit but not effort-cost was correlated with diminished motivation. Reward-discounting and sensitivity indices were generally unrelated to other symptom dimensions, antipsychotic dose and cognitive deficits.

CONCLUSION

This study provides the first evidence of cognitive effort-based decision-making impairment in FEP, and indicates that decreased effort expenditure is associated with amotivation. Our findings further suggest that abnormal effort allocation and amotivation might primarily be related to blunted reward valuation. Prospective research is required to clarify the utility of effort-based measures in predicting amotivation and functional outcome in FEP.

Perspective on medication decisions following remission from first-episode psychosis

While antipsychotics (APs) could provide rapid relief of positive symptoms in psychotic disorders, their usage is often associated with side effects, stigma and inconveniences. For these and other reasons, many psychosis patients, particularly those of first-episode psychosis (FEP) in remission, wish to discontinue maintenance treatment. The current review aims to discuss the strategies of AP treatment following remission from FEP, with particular emphasis on the evaluation of outcomes following AP discontinuation. Upon review of relevant literature, three potential strategies are put forth for treatment-responsive, remitted FEP patients: a) life-long maintenance treatment, b) AP discontinuation during second year of treatment, or c) AP discontinuation after three years of treatment. In theory, the first strategy presents the safest option for maximal symptom control. However, a rigorous RCT indicates that if AP discontinuation is to be attempted, the third strategy best prevents poor long-term clinical outcomes. Further data is needed to address the costs and benefits of each treatment strategy, compare AP-free patients with those on different types of APs, as well as explore even longer-term outcomes.

The role of social relatedness and self-beliefs in social functioning in first-episode psychosis: Are we overestimating the contribution of illness-related factors?

Objective

Numerous research studies have demonstrated an association between higher symptom severity and cognitive impairment with poorer social functioning in first-episode psychosis (FEP). By contrast, the influence of subjective experiences, such as social relatedness and self-beliefs, has received less attention. Consequently, a cohesive understanding of how these variables interact to influence social functioning is lacking.

Method

We used structural equation modeling to examine the direct and indirect relationships among neurocognition (processing speed) and social cognition, symptoms, and social relatedness (perceived social support and loneliness) and self-beliefs (self-efficacy and self-esteem) in 170 individuals with FEP.

Results

The final model yielded an acceptable model fit (χ² = 45.48, comparative fit index = 0.96; goodness of fit index = 0.94; Tucker–Lewis index = 0.94; root mean square error of approximation = 0.06) and explained 45% of social functioning. Negative symptoms, social relatedness, and self-beliefs exerted a direct effect on social functioning. Social relatedness partially mediated the impact of social cognition and negative symptoms on social functioning. Self-beliefs also mediated the relationship between social relatedness and social functioning.

Conclusions

The observed associations highlight the potential value of targeting social relatedness and self-beliefs to improve functional outcomes in FEP. Explanatory models of social functioning in FEP not accounting for social relatedness and self-beliefs might be overestimating the effect of the illness-related factors.

Onset and transition of and recovery from adverse development: Study methodology

AIM

Early intervention programs for first-episode psychosis have led to the awareness that the period before onset of a first episode is important in light of early intervention. This has induced a focus on the so-called 'at risk mental state' (ARMS). Individuals with ARMS are at increased risk for later psychotic disorder, but also for other psychiatric disorders as well as poor psychosocial functioning. Thus, adequate detection and treatment of ARMS is essential.

METHODS

Since 2018, screening for and treatment of ARMS is recommended standard care in the Netherlands. Implementation is still ongoing. We initiated a naturalistic long-term cohort study of ARMS individuals, the onset and transition of and recovery from adverse development (OnTheROAD) study, with the aim to monitor course and outcome of symptoms and psychosocial functioning over time, as well as patterns of comorbidity and associations with factors of risk and resilience. To this end, participants complete a broad battery of instruments at baseline and yearly follow-up assessments up to 3 years. Outcome is defined in terms of symptom severity level, functioning and quality of life. In particular, we aim to investigate the impact of negative symptoms as part of the ARMS concept. Results from this study can aid in refining the existing ARMS criteria, understanding the developmental course of ARMS and investigating the hypothesized pluripotentiality in outcome of ARMS. New knowledge may inform the further development of specialized early interventions.

RESULTS AND CONCLUSIONS

In this article, we describe the rationale, outline and set-up of OnTheROAD.

Prepared for transition? A cross-sectional descriptive study of the gains attained in early psychosis programs

AIM

To examine the degree to which youth identified as ready for discharge from three Canadian early psychosis intervention (EPI) programs had achieved optimal outcomes (ie, symptom remission, quality of life, self-esteem and functioning).

METHODS

This cross-sectional descriptive study is part of a larger study assessing the effectiveness of an evidence-based intervention to sustain the gains acquired in EPI programs in two Canadian provinces (Ontario and Nova Scotia), as youth transition from EPI services to community-based care. Baseline data collected from 39 participants receiving usual treatment in these three EPI programs comprised the comparison group. Participants completed measures to assess symptoms, quality of life, self-esteem and functional level just prior to discharge.

RESULTS

Participants demonstrated lower levels of symptoms, greater quality of life, greater self-esteem and greater levels of functioning, following EPI treatment when compared to similar youth described in the literature. These findings suggest that study participants had achieved optimal outcomes following EPI treatment.

CONCLUSION

The study findings have laid the ground work for the current Canadian Institutes of Health Research partnership study in which our research group is assessing the effectiveness of an evidence-based transitional intervention in order to address critical psychosocial issues of identity, stigma, effective relationships and meaningful life goals, along with the development of an individualized 'passport for transition'. It is anticipated that implementing an evidence-based transitional intervention will support participants to maintain the gains made in EPI programs once they transition to community-based care and will inform future research addressing this challenging issue.

Inter-relationships among psychopathology, premorbid adjustment, cognition and psychosocial functioning in first-episode psychosis: a network analysis approach

BACKGROUND

Better understanding of interplay among symptoms, cognition and functioning in first-episode psychosis (FEP) is crucial to promoting functional recovery. Network analysis is a promising data-driven approach to elucidating complex interactions among psychopathological variables in psychosis, but has not been applied in FEP.

METHOD

This study employed network analysis to examine inter-relationships among a wide array of variables encompassing psychopathology, premorbid and onset characteristics, cognition, subjective quality-of-life and psychosocial functioning in 323 adult FEP patients in Hong Kong. Graphical Least Absolute Shrinkage and Selection Operator (LASSO) combined with extended Bayesian information criterion (BIC) model selection was used for network construction. Importance of individual nodes in a generated network was quantified by centrality analyses.

RESULTS

Our results showed that amotivation played the most central role and had the strongest associations with other variables in the network, as indexed by node strength. Amotivation and diminished expression displayed differential relationships with other nodes, supporting the validity of two-factor negative symptom structure. Psychosocial functioning was most strongly connected with amotivation and was weakly linked to several other variables. Within cognitive domain, digit span demonstrated the highest centrality and was connected with most of the other cognitive variables. Exploratory analysis revealed no significant gender differences in network structure and global strength.

CONCLUSION

Our results suggest the pivotal role of amotivation in psychopathology network of FEP and indicate its critical association with psychosocial functioning. Further research is required to verify the clinical significance of diminished motivation on functional outcome in the early course of psychotic illness.

Symptom remission at 12-weeks strongly predicts long-term recovery from the first episode of psychosis

BACKGROUND

To determine the baseline individual characteristics that predicted symptom recovery and functional recovery at 10-years following the first episode of psychosis.

METHODS

AESOP-10 is a 10-year follow up of an epidemiological, naturalistic population-based cohort of individuals recruited at the time of their first episode of psychosis in two areas in the UK (South East London and Nottingham). Detailed information on demographic, clinical, and social factors was examined to identify which factors predicted symptom and functional remission and recovery over 10-year follow-up. The study included 557 individuals with a first episode psychosis. The main study outcomes were symptom recovery and functional recovery at 10-year follow-up.

RESULTS

At 10 years, 46.2% (n = 140 of 303) of patients achieved symptom recovery and 40.9% (n = 117) achieved functional recovery. The strongest predictor of symptom recovery at 10 years was symptom remission at 12 weeks (adj OR 4.47; CI 2.60-7.67); followed by a diagnosis of depression with psychotic symptoms (adj OR 2.68; CI 1.02-7.05). Symptom remission at 12 weeks was also a strong predictor of functional recovery at 10 years (adj OR 2.75; CI 1.23-6.11), together with being from Nottingham study centre (adj OR 3.23; CI 1.25-8.30) and having a diagnosis of mania (adj OR 8.17; CI 1.61-41.42).

CONCLUSIONS

Symptom remission at 12 weeks is an important predictor of both symptom and functional recovery at 10 years, with implications for illness management. The concepts of clinical and functional recovery overlap but should be considered separately.

Factors influencing subjective recovery of people with recent-onset psychosis: A cross-sectional study in a low-income sub-Saharan country

People with psychosis were traditionally believed to have a chronic deteriorating condition with no hope of recovery. Recent studies have shown varied levels of recovery across countries. However, evidence from low-income, particularly African countries is scant. This study aimed to investigate levels of subjective recovery of people with recent-onset psychosis and identify its influencing factors. A cross-sectional study was conducted among 263 outpatients with recent-onset psychosis in a low-income country, Ethiopia. Psychiatric outpatients were randomly selected, and assessed by a set of questionnaires measuring their psychosocial, clinical and physical health conditions. Hierarchical multiple regression tests were used to identify factors influencing subjective recovery. The level of subjective recovery was found to be high, with a mean Questionnaire about the Process of Recovery score of 44.17. Individuals with higher quality of life were found to have significantly better subjective recovery level. Hopeless and centrally obese individuals were found to have significantly lower level of subjective recovery. Despite the limitations associated with a cross sectional study design, the results suggest that individuals with recent-onset psychosis in Ethiopia may have a better level of subjective recovery than those in high-income countries and their recovery is influenced by quality of life, hopelessness and central obesity.

Negative symptom subgroups have different effects on the clinical course of schizophrenia after the first episode: A 24-month follow up study

Objective:

The aim of this study was to assess the factor structure of negative symptoms in first-episode schizophrenia (FES), and to examine the relationship of these factors with clinical course and functioning of patients during the two-year follow up.

Method:

We assessed 174 drug-naïve patients with FES using Brief Psychiatric Rating Scale-Expanded (BPRS), Scale for the Assessment of Negative Symptoms (SANS), Scale for the Assessment of Positive Symptoms (SAPS), and Global Assessment of Functioning (GAF) and a cognitive battery at admission. The scales were repeated monthly during follow up. We recorded the patients’ functioning levels, remission, and work status after 12 and 24 months.

Results:

A two-factor structure was found at the baseline, whereas one factor was found after 12 and 24 months. Expressive deficit (ED) factor consisted of alogia and blunted affect, and motivation-pleasure deficit (MPD) factor consisted of avolition and anhedonia. ED factor was related to earlier onset and remission, and it was negatively correlated with duration of education and cognitive test scores. MPD factor was related to duration of untreated psychosis, family history of schizophrenia, and work status, and it appeared as the only independent variable that contributed to the baseline GAF score in linear regression analysis.

Conclusion:

Our findings suggest that the factors have different aetiologies and impacts on the clinical course of schizophrenia and functioning after FES.

Symptomatic and Functional Remission in Young Adults with a Psychotic Disorder in a Rehabilitation Focused Team

The aim of this study is to assess symptomatic remission (SR) and functional remission (FR) in a rehabilitation focused program for young adults with a psychotic disorder in the Netherlands, and to investigate which individual and mental health care factors are associated with SR and/or FR, by using Routine Outcome Monitoring data and data on met needs and unmet needs for care. Data of 287 young adults were collected. Almost 40% achieved or maintained SR, 34% FR, and 26% achieved or maintained both. In addition to sociodemographic factors, living independently, paid employment, higher levels of compliance with treatment, and better fulfillment of unmet needs for care in relation to psychological distress, company and daytime activities were associated with better outcomes on SR and/or FR. Our findings underscore that to successfully improve and sustain remission in young adults with a psychotic disorder, it is needed to conduct specific research into the relationship between SR and FR.

Characterizing Covariant Trajectories of Individuals at Clinical High Risk for Psychosis Across Symptomatic and Functional Domains

OBJECTIVE

The authors sought to characterize differences in outcomes among help-seeking individuals at clinical high risk for psychosis by identifying covariant longitudinal patterns of symptoms and functioning.

METHODS

Group-based multitrajectory modeling was applied to longitudinal ratings of four symptom domains (positive, negative, disorganized, general) and general functioning among clinical high-risk individuals in an initial discovery sample (N=422). An independent sample (N=133) was used to test replicability.

RESULTS

Three trajectory groups were identified among clinical high-risk individuals in the discovery sample: group 1 (30%) exhibited substantial improvement across all domains, with half reaching positive outcomes for both functioning and positive symptoms; group 2 (49%) exhibited moderate impairments across domains, with approximately one-quarter meeting criteria for positive outcomes; the remaining participants (group 3; 22%) exhibited consistent levels of severe impairment across domains and did not experience positive outcomes. These trajectory groups and remission patterns were replicated in an independent sample.

CONCLUSIONS

Replicable subgroups of help-seeking clinical high-risk cases can be ascertained based on distinctive profiles of change over time in symptoms and functioning. Within each of the three identified subgroups, similar patterns of change (i.e., rapid, moderate, or no improvement) were observed across the four symptom domains and functioning. This consistency of change over time across domains within each subgroup is a novel observation supporting the syndrome consistency of clinical high-risk symptoms and signs. The observed trajectory subgroups are suggestive of different degrees of need for clinical interventions, ranging from minimal or supportive for about one-third of cases to increasingly intensive among the remainder.

Negative symptom severity at discharge from an index hospitalization and subsequent use of psychiatric care resources: A retrospective 1-year follow-up study on 450 patients with schizophrenia spectrum disorders

Negative symptoms of schizophrenia have a great impact on patients' functioning and are among the most important contributors to subject's disability. However, few studies have assessed the role of type and severity of symptomatology of schizophrenia on the psychiatric care resource utilization. We investigated if the clinical profile of patients at discharge from an index hospitalization might be associated with a different use of psychiatric care resources in the subsequent 1-year period in a large population of patients with schizophrenia spectrum disorders. Clinical records of 450 patients with schizophrenia spectrum disorders admitted in an acute psychiatric inpatient service and subsequently followed in the outpatient services of the same Department were reviewed. Patients with more severe negative symptoms at discharge from hospital showed a higher number and duration of hospitalizations in the 1-year follow-up, as well as a higher number of rehabilitative residential admissions than patients with milder severity of negative symptoms. The same was true for patients with predominant negative symptoms. A global resource utilization index indicated a higher use of psychiatric resources in patients with higher severity of negative symptoms. In conclusion, showing moderate to severe negative symptoms versus positive symptoms at discharge from a hospitalization for an acute exacerbation of schizophrenia spectrum disorder does predict a higher use of psychiatric care resources. This underlines the importance of relieving negative symptoms even in the acute phase of treatment and the need to develop more effective treatments for this symptom dimension.

Sex Differences in Clinical and Functional Outcomes among Patients Treated in an Early Intervention Service for Psychotic Disorders: An Observational Study

OBJECTIVE

It has been shown that men with a longstanding psychotic disorder have worse clinical and functional outcomes than women. Our objectives were to examine whether these sex differences are also present among patients treated in an early intervention service (EIS) for psychosis and to determine if these differences are related to risk factors other than sex.

METHOD

Patients (N = 569) were assessed for demographic/clinical characteristics at entry and for symptoms/functioning over 2 years of treatment. Clinical outcomes included remission of positive, negative, and total symptoms. Functional outcomes included good functioning and functional remission. Logistic regression models examined the relationship between sex and outcomes after 1 and 2 years of treatment while controlling for the influence of other risk factors.

RESULTS

Men reported to be less educated and have a longer duration of untreated psychosis, poorer childhood and early adolescent premorbid functioning, higher rates of substance abuse/dependence disorders, greater severity of baseline negative symptoms, and poorer baseline social/occupational functioning than women. Women were more likely to achieve symptom remission than men after 2 years of treatment (negative odds ratio [OR], 1.69; 95% confidence interval [CI], 1.02 to 2.78; total OR, 1.79; 95% CI, 1.08 to 2.98). Women were also more likely than men to exhibit good functioning (OR, 1.61; 95% CI, 1.04 to 2.49) after 1 but not after 2 years of treatment. These results did not persist after controlling for other risk factors that could confound these associations (i.e., childhood premorbid functioning and age at onset of psychosis).

CONCLUSIONS

Sex differences seen in outcomes among patients treated in an EIS for psychosis may be largely influenced by the disparity of other risk factors that exist between the 2 sexes.

Medication adherence in first-episode psychosis patients in Singapore

AIM

Early intervention programmes for first episode psychosis (FEP) aim to reduce the duration of untreated psychosis (DUP) and improve functional outcomes. The sustained maintenance of improved outcomes depends largely on patients' adherence to prescribed treatment. This paper examines the prevalence of non-adherence in a cohort of patients with FEP and the sociodemographic and clinical factors associated with non-adherent behaviour.

METHODS

The sample included consecutive patients accepted from 2007 to 2012 into the Early Psychosis Intervention Programme (EPIP) in Singapore. Sociodemographic variables as well as DUP, insight, severity of psychopathology and clinical diagnoses were collected. Patients were assessed at baseline and 1 year with the PANSS and Global Assessment of Functioning Scale (GAF). Medication adherence was grouped into 3 categories: no-adherence, partial adherence and regular adherence.

RESULTS

Of the 445 patients included, 51% were male with a mean age of 26.3 years, 74.6% had schizophrenia spectrum and delusional disorders, 14% had affective psychosis and 11.3% had brief psychotic disorder or psychotic disorder not otherwise specified. At 1 year follow up, 65.5% reported regular adherence, 18.7% were partially adherent and 15.8% were non-adherent. Non-adherence was correlated with male gender, living alone and having poorer judgement and insight. Partial adherence was associated with Malay ethnicity and having undergone national service.

CONCLUSION

Medication adherence is prevalent in FEP and associated with a variety of factors. This study supports the use of culturally appropriate interventions in addressing barriers to adherence. Further studies would need to be done to address specific factors affecting adherence outcomes.

Longitudinal trajectory of early functional recovery in patients with first episode psychosis

BACKGROUND

There is a large variability in the recovery trajectory and outcome of first episode of psychosis [FEP] patients. To date, individuals' outcome trajectories at early stage of illness and potential risk factors associated with a poor outcome trajectory are largely unknown. This study aims to apply three separate predictors (positive symptoms, negative symptoms, and soft neurological signs) to identify homogeneous function outcome trajectories in patients with FEP using objective data-driven methods, and to explore the potential risk /protective factors associated with each trajectory.

METHODS

A total of 369 first episode patients (93% antipsychotic naive) were included in the baseline assessments and followed-up at 4-8 weeks, 6 months, and 1 year. K means cluster modeling for longitudinal data (kml3d) was used to identify distinct, homogeneous clusters of functional outcome trajectories. Patients with at least 3 assessments were included in the trajectory analyses (N = 129). The Scale for the Assessment of Negative Symptoms (SANS), Scale for the Assessment of Positive Symptoms (SAPS), and Neurological examination abnormalities (NEA) were used as predictors against Global Assessment of Functioning Scale (GAF).

RESULTS

In each of the three predictor models, four distinct functional outcome trajectories emerged: "Poor", "Intermediate", High" and "Catch-up". Individuals with male gender; ethnic minority status; low premorbid adjustment; low executive function/IQ, low SES, personality disorder, substance use history may be risk factors for poor recovery.

CONCLUSIONS

Functioning recovery in individuals with FEP is heterogeneous, although distinct recovery profiles are apparent. Data-driven trajectory analysis can facilitate better characterization of individual longitudinal patterns of functioning recovery.

Predictors of remission during acute treatment of first-episode schizophrenia patients involuntarily hospitalized and treated with algorithm-based pharmacotherapy: Secondary analysis of an observational study

AIM

Early clinical response predicts symptomatic remission and recovery in the maintenance treatment phase of first-episode schizophrenia (FES). However, little is known about predictors of symptomatic remission during acute treatment of severely ill patients with FES. Here, we conducted a secondary analysis of our retrospective observational study, which examined response, remission and treatment-resistance rates in seriously ill patients with FES spectrum disorders involuntarily hospitalized and treated with algorithm-based pharmacotherapy.

METHODS

We performed a retrospective chart review of 131 involuntarily admitted patients with schizophrenia or schizoaffective disorder. Our algorithm aimed to delay olanzapine treatment, standardize medications and suggest initiation of clozapine after failure of third-line antipsychotic treatment. The duration of each adequate antipsychotic treatment at an optimal dosage was 4 weeks or more. Remission was defined using the symptom-severity component of consensus remission criteria. A logistic regression model was applied to identify significant predictors of remission at discharge.

RESULTS

Overall, 74 patients (56%) were in remission at discharge. Non-remitters were hampered from becoming remitters mainly by the presence of negative symptoms. There were no differences in first-line antipsychotics, dosage of antipsychotics at time of response and adherence rates to algorithm-based pharmacotherapy between remitters and non-remitters. Shorter duration of untreated psychosis, favourable early response and less negative symptoms at baseline were identified as independent predictors of remission at discharge.

CONCLUSIONS

The importance of early intervention and specific and adequate treatments of negative symptoms is highlighted.

Negative symptoms in first-episode psychosis: Clinical correlates and 1-year follow-up outcomes in London Early Intervention Services

AIM

Negative symptoms (NS) have been associated with poor outcome and remain difficult to treat in patients with psychosis. This study examined the association of NS with clinical features at first presentation to mental health services for psychosis and with outcomes at 1-year follow-up.

METHODS

Clinical data were utilized from five London Early Intervention Services (EIS) included in the MiData audit database. The sample comprised 484 first-episode psychosis patients with complete Positive and Negative Syndrome Scale data at baseline and 1-year follow-up. Multiple imputation (N = 50) was conducted to account for missing follow-up data.

RESULTS

Baseline NS were associated with male gender (B = -1.63, P < .05), younger age at onset (B = -.15, P <. 05), a higher level of impairment on the Global Assessment of Functioning (disability) Scale at baseline (B = -.19, P <. 010), an absence of reported substance misuse prior to baseline assessment (B = -3.05, P <. 001) and unemployment at baseline (B = -.93, P <. 01). At 1-year follow-up, NS at presentation were associated with worse Global Assessment of Functioning Scale for symptom (B = -.28, P < .01) and disability (B = -.27, P <. 05) and with hospital admission (OR = 1.06, P < .01).

CONCLUSIONS

Negative symptoms at presentation to EIS were associated with worse functioning at entry and poorer outcomes 1 year later. Future research is required to better understand the aetiology and trajectories of NS in early psychosis and propose novel targeted interventions.

Men and women respond differently to antipsychotic drugs

BACKGROUND

Because women are often perceived as having better outcomes than men in psychotic illnesses such as schizophrenia - women are less often in hospital, have a lower suicide rate, are less often involved with the law, enjoy better relationships with family and friends - the question arises as to whether or not this apparent advantage is attributable to a gender difference in antipsychotic response.

OBJECTIVE

The aim of this paper is to critically review the quantitative and qualitative literature on gender difference in antipsychotic response sourced mainly from medical databases of the last ten years.

FINDINGS

There are theoretical reasons why women's effective doses of antipsychotics might need to be lower than guidelines recommend for men, especially as regards olanzapine and clozapine, but, because there are so many variables that impinge on antipsychotic response, it is difficult to provide definitive guidance. What is evident is that some antipsychotic side effects, weight gain for instance, are more worrisome for women than for men. It is also evident that, after menopause, women need an increase in their antipsychotic dose; other reproductive stages in women's lives require special prescribing considerations as well.

CONCLUSION

There is a science, and an art, to prescribing antipsychotics, which needs to take gender into account. This article is part of the issue entitled 'Special Issue on Antipsychotics'.

Effort-based decision-making impairment in patients with clinically-stabilized first-episode psychosis and its relationship with amotivation and psychosocial functioning

Effort-based decision-making has recently been proposed as a potential mechanism contributing to motivational deficits (amotivation) in psychotic disorder. Previous research has identified altered effort allocation in chronic schizophrenia, but produced mixed results regarding its relationship with amotivation. No study has investigated effort allocation in first-episode psychosis (FEP). We examined effort-based decision-making in 45 clinically-stabilized FEP patients and 45 demographically-matched controls, using Effort-Expenditure for Reward Task (EEfRT) which measures allocation of physical effort for monetary reward at varying magnitude and probability levels. Our results showed that FEP patients did not demonstrate overall reduction in effort expenditure but displayed reduced willingness to expend effort for high-value/high-probability reward as compared to controls. In particular, such selective effort-related impairment was most pronounced in patients with high levels of amotivation. Furthermore, reduced allocation of greater effort for higher probability reward was related to poorer psychosocial functioning. Decreased effort exertion was generally unrelated to other symptom dimensions, self-report anhedonia, antipsychotic dose and cognitive deficits. This study thus provides the first evidence of effort-based decision-making impairment in FEP, and indicates that first-episode patients were not generally effort-averse but exhibited inefficient effort allocation by failing to make high-effort choices to maximize reward receipt. Our findings affirm the critical role of amotivation on aberrant effort allocation, and support the link between laboratory-based effort-cost measures and real-world psychosocial functioning in medicated FEP. Further longitudinal research is required to clarify trajectory of suboptimal effort allocation and its potential utility in predicting amotivation and functional outcomes in the early course of illness.

Conceptualizations of subjective recovery from recent onset psychosis and its associated factors: A systematic review

AIM

There is no standard definition of "subjective recovery" from psychosis, its nature is currently contested and debated among service-users and professionals. Individual studies have explored conceptualizations of subjective recovery from recent onset psychosis, but there have been no previously published systematic reviews on the topic. The aim of this review was to examine and synthesize quantitative and qualitative studies examining the concept of subjective recovery from recent onset psychosis and identify common factors associated with this recovery process.

METHODS

Relevant electronic databases (Medline, CINAHL, PsychInfo and ProQuest Dissertations and Theses) were searched and hand searches were also carried out. Publications in each database from the inceptions of the databases to April 12, 2017 were included. Data from selected articles were extracted using a piloted extraction form and thematic integrative analysis was performed.

RESULTS

Ten studies with different study designs were included in this review. Subjective recovery was conceptualized into 3 main themes: "recovery as outcome", "recovery as process" and "endeavours during recovery". Factors contributing to subjective recovery were categorized into 4 main themes; "treatment related", "illness related", "individual related" and "social environment" related. Non-linear and subjective nature of the process of recovery were reinforced by the review findings.

CONCLUSIONS

Studies in subjective recovery from recent onset psychosis are limited to developed countries. Acquiring hope and self-confidence, overcoming symptoms and stigma through mobilizing all resources available were accentuated in conceptualizing subjective recovery and related factors. Recovery-oriented health care services should acknowledge individual differences and involve service users in their care decisions.
