Abstract
BACKGROUND Cognitive Remediation (CR) is an evidence-based therapy targeting cognitive difficulties in people with psychosis to promote functional recovery, but it is rarely implemented routinely. To reach more individuals, CR is beginning to be delivered remotely, but there is limited evidence to support the acceptability of this method. AIMS To evaluate the acceptability and feasibility of remote therapist-supported CR in people with psychosis and estimate its cost and potential benefits. METHODS A case-series with all participants assessed before and after therapy with measures of personal goal attainment (main outcome), cognition, functioning and symptoms. Acceptability was assessed with post-therapy interviews. Feasibility was assessed using proportions and confidence intervals on pre-specified parameters. Indication of benefits was assessed with exploratory analyses comparing baseline and post-therapy scores on the pre-specified outcomes. The cost of providing remote CR was assessed from both healthcare and societal perspectives. RESULTS Twenty-nine participants started therapy with two dropping out; on average participants attended 25.5 sessions. Interviews suggested that remote CR had good acceptability and led to perceived benefits. Significant and large improvements were observed on goal attainment. Cost analyses suggest that remote CR has the same health care cost as face-to-face therapy but a lower societal cost. CONCLUSIONS Our results support the use of remote CR in psychosis services as an alternative delivery modality. This method may improve adherence, attendance and be more convenient for service users. Possible barriers such as poor digital literacy or appropriate device ownership should be addressed before starting therapy.

Abstract
BACKGROUND Digital health interventions (DHIs) have significant potential to upscale treatment access to people experiencing psychosis but raise questions around patient safety. Adverse event (AE) monitoring is used to identify, record, and manage safety issues in clinical trials, but little is known about the specific content and context contained within extant AE reports. This study aimed to assess current AE reporting in DHIs. STUDY DESIGN A systematic literature search was conducted by the iCharts network (representing academic, clinical, and experts by experience) to identify trials of DHIs in psychosis. Authors were invited to share AE reports recorded in their trials. A content analysis was conducted on the shared reports. STUDY RESULTS We identified 593 AE reports from 18 DHI evaluations, yielding 19 codes. Only 29 AEs (4.9% of total) were preidentified by those who shared AEs as being related to the intervention or trial procedures. While overall results support the safety of DHIs, DHIs were linked to mood problems and psychosis exacerbation in a few cases. Additionally, 27% of studies did not report information on relatedness for all or at least some AEs; 9.6% of AE reports were coded as unclear because it could not be determined what had happened to participants. CONCLUSIONS The results support the safety of DHIs, but AEs must be routinely monitored and evaluated according to best practice. Individual-level analyses of AEs have merit to understand safety in this emerging field. Recommendations for best practice reporting in future studies are provided.

Abstract
Cognitive impairment is common in people with schizophrenia (PWS). To detect the presence and its consequences, cognitive measures with sound psychometric properties are needed. However, these are lacking especially in low-income countries. Hence, we developed the Ethiopian Cognitive Assessment battery in Schizophrenia (ECAS). In this study, we evaluated the psychometric properties of the ECAS in a cross-sectional study involving 350 PWS. Confirmatory factor analysis demonstrated a one-factor solution. ECAS score correlated significantly but weakly with a disability measure (r = -0.13, p = 0.02) and symptom dimensions of PANSS (r between -0.12 and -0.29, p < 0.05), except for positive symptoms (r = -0.10, p > 0.05). Years of education (β = 0.12, 95% CI (0.09, 0.14), p < 0.001), male sex (β = 0.22, 95% CI (0.05, 0.39)), age β = -0.02, 95% CI (-0.03, -0.01), and medication side effects (β = -0.03, 95% CI (-0.06, -0.01), p = 0.021) were significantly associated with the composite score of ECAS. The Item Response Theory analysis showed that the tool best functions among participants with moderate cognitive impairment (difficulty coefficient between -1.12 and 0.27). The Differential Item Functioning analyses showed that education had a positive contribution on Digit Symbol Substitution Test (MH OR = 2.64, 95% CI (1.34, 5.20)). The results showed that ECAS is valid in assessing cognition in PWS in low-resource settings.

Abstract
OBJECTIVE Auditory hallucinations (hearing voices) have been associated with a range of altered cognitive functions, pertaining to signal detection, source-monitoring, memory, inhibition and language processes. Yet, empirical results are inconsistent. Despite this, several theoretical models of auditory hallucinations persist, alongside increasing emphasis on the utility of a multidimensional framework. Thus, clarification of current evidence across the broad scope of proposed mechanisms is warranted. METHOD A systematic search of the Web of Science, PubMed and Scopus databases was conducted. Records were screened to confirm the use of an objective behavioural cognitive task, and valid measurement of hallucinations specific to the auditory modality. RESULTS Auditory hallucinations were primarily associated with difficulties in perceptual decision-making (i.e. reduced sensitivity/accuracy for signal-noise discrimination; liberal responding to ambiguity), source-monitoring (i.e. self-other and temporal context confusion), working memory and language function (i.e. reduced verbal fluency). Mixed or limited support was observed for perceptual feature discrimination, imagery vividness/illusion susceptibility, source-monitoring for stimulus form and spatial context, recognition and recall memory, executive functions (e.g. attention, inhibition), emotion processing and language comprehension/hemispheric organisation. CONCLUSIONS Findings were considered within predictive coding and self-monitoring frameworks. Of concern was the portion of studies which - despite offering auditory-hallucination-specific aims and inferences - employed modality-general measures, and/or diagnostic-based contrasts with psychologically healthy individuals. This review highlights disparities within the literature between theoretical conceptualisations of auditory hallucinations and the body of rigorous empirical evidence supporting such inferences. Future cognitive investigations, beyond the schizophrenia-spectrum, which explicitly define and measure the timeframe and sensory modality of hallucinations, are recommended.

Abstract
BACKGROUND Hallucinations have been linked to failures in metacognitive reflection suggesting an association between hallucinations and overestimation of performance, although the cross-sectional findings are inconsistent. This inconsistency may relate to the fluctuating hallucinatory experiences that are not captured in cross-sectional studies. Ecological Momentary Assessment (EMA) captures in-the-moment experiences over time so can identify causal relationships between variables such as the associations between metacognition and hallucinatory experience in daily life and overcome problems in cross-sectional designs. METHODS Participants (N = 41) experiencing daily hallucinations completed baseline questionnaires and smartphone surveys 7 times per day for 14 days. They were prompted to identify a task they would complete in the next 4 h and to make metacognitive predictions around the likelihood of completing the task, the difficulty of the task, and how well they would complete it (standard of completion). RESULTS 76 % finished the 14-days of assessment with an average of 42.2 % survey completion. Less accurate metacognition was associated with more hallucinations, but less accurate likelihood and standard of completion was associated with fewer hallucinations. Using a cross-lagged analysis, metacognitive predictions around the likelihood of completion (p < .001) and standard of completion (p = .01) predicted hallucination intensity at the following timepoint, and metacognitive predictions regarding likelihood of completion (p = .02) predicted hallucination control at the following timepoint. DISCUSSION Interventions that aim to improve metacognitive ability in-the-moment may serve to reduce the intensity and increase the control of hallucinations.

Abstract
BACKGROUND To provide precision cognitive remediation therapy (CR) for schizophrenia, we need to understand whether the mechanism for improved functioning is via cognition improvements. This mechanism has not been rigorously tested for potential moderator effects. STUDY DESIGN We used data (n = 377) from a randomized controlled trial using CIRCuiTS, a therapist-supported CR, with participants from first-episode psychosis services. We applied structured equation modeling to test whether: (1) CR hours explain the goal attainment functional outcome (GAS) at posttreatment, (2) global cognitive improvement mediates GAS, and if (3) total symptoms moderate the CR hours to cognitive improvement pathway, and/or negative symptoms moderate the cognition to functioning pathway, testing moderator effects via the mediator or directly on CR hours to functioning path. STUDY RESULTS CR produced significant functioning benefit for each therapy hour (Coeff = 0.203, 95% CI 0.101-0.304, P < .001). The mediated path from CR hours to cognition and cognition to functioning was small and nonsignificant (Coeff = 0.014, 95% CI = -0.010, 0.037, P = .256). Total symptoms did not moderate the path to cognition (P = .211) or the direct path to outcome (P = .896). However, negative symptoms significantly moderated the effect of cognitive improvements on functioning (P = .015) with high negative symptoms reducing the functional gains of improved cognition. CONCLUSIONS Although cognitive improvements were correlated with functioning benefit, they did not fully explain the positive effect of increased therapy hours on functioning, suggesting additional CR factors also contribute to therapy benefit. Negative symptoms interfere with the translation of cognitive improvements into functional gains so need consideration.

Abstract
BACKGROUND Cognitive impairment is common with schizophrenia spectrum disorders. Cognitive remediation (CR) is effective in improving global cognition, but not all individuals benefit from this type of intervention. A better understanding of the potential mechanism of action of CR is needed. One proposed mechanism is reward learning (RL), the cognitive processes responsible for adapting behavior following positive or negative feedback. It is proposed that the structure of CR enhances RL and motivation to engage in increasingly challenging tasks, and this is a potential mechanism by which CR improves cognitive functioning in schizophrenia. OBJECTIVE Our primary objective is to examine reward processing in individuals with schizophrenia before and after completing CR and to compare this with a group of matched clinical controls. We will assess whether RL mediates the relationship between CR and improved cognitive function and reduced negative symptoms. Potential differences in social RL and nonsocial RL in individuals with schizophrenia will also be investigated and compared with a healthy matched control group. METHODS We propose a clinical, nonrandomized, pre-post pilot study comparing the impact of CR on RL and neurocognitive outcomes. The study will use a combination of objective and subjective measures to assess neurocognitive, psychiatric symptoms, and neurophysiological domains. A total of 40 individuals with schizophrenia spectrum disorders (aged 18-35 years) will receive 12 weeks of CR therapy (n=20) or treatment as usual (n=20). Reward processing will be evaluated using a reinforcement learning task with 2 conditions (social reward vs nonsocial reward) at baseline and the 12-week follow-up. Functional magnetic resonance imaging responses will be measured during this task. To validate the reinforcement learning task, RL will also be assessed in 20 healthy controls, matched for age, sex, and premorbid functioning. Mixed-factorial ANOVAs will be conducted to evaluate treatment group differences. For the functional magnetic resonance imaging analysis, computational modeling will allow the estimation of learning parameters at each point in time, during each task condition, for each participant. We will use a variational Bayesian framework to measure how learning occurred during the experimental task and the subprocesses that underlie this learning. Second-level group analyses will examine how learning in patients differs from that observed in control participants and how CR alters learning efficiency and the underlying neural activity. RESULTS As of September 2023, this study has enrolled 15 participants in the CR group, 1 participant in the treatment-as-usual group, and 11 participants in the healthy control group. Recruitment is expected to be completed by September 2024. Data analysis is expected to be completed and published in early 2025. CONCLUSIONS The results of this study will contribute to the knowledge of CR and RL processes in severe mental illness and the understanding of the systems that impact negative symptoms and cognitive impairments within this population.

Abstract
AIM Psychosis spectrum disorders continue to rank highly among causes of disability. This has resulted in efforts to expand the range of treatment targets beyond symptom remission to include other recovery markers, including social and occupational function and quality of life. Although the efficacy of psychosocial interventions in early psychosis has been widely reported, the acceptability of these interventions is less well-known. This study explores the participant perspective on a novel, psychosocial intervention combining cognitive remediation and social recovery therapy. METHODS We employed a qualitative research design, based on semi-structured interviews and reflexive thematic analysis. Six participants with early psychosis were recruited from the intervention arm of a randomized pilot study, three women and three men, aged between 22 and 27 years. RESULTS Four themes were developed through the analytical process, namely, (1) a solid therapeutic foundation, (2) multi-directional flow of knowledge, (3) a tailored toolset, and (4) an individual pathway to recovery. Participants also provided pragmatic feedback about how to improve the delivery of the therapy assessments and intervention. Both the themes and pragmatic feedback are described. CONCLUSIONS People with early psychosis described the intervention as acceptable, engaging, helpful and person-centred, suggesting its potential role in a multicomponent therapy model of early intervention in psychosis services. Participants in this study also highlight the importance of an individualized approach to therapy, the vital role of the therapeutic relationship and the ecological validity and value of adopting an assertive outreach delivery, providing therapy outside a conventional clinic setting.

Abstract
BACKGROUND AND HYPOTHESIS Cognitive difficulties significantly burdened people with schizophrenia (PWS). However, cognitive assessment is often unavailable in low- and middle-income counties (LMICs) due to a lack of validated and culturally adapted cognitive assessment tools. In this study, we developed and evaluated a culturally sensitive cognitive battery for PWS in Ethiopia. STUDY DESIGN This study was conducted in three phases. First, we selected appropriate tests through an instrument selection procedure and created a new battery. Then, we rigorously adapted the tests using culturally competent procedures, including cognitive interviewing and expert meetings. Finally, we tested the new battery in 208 PWS and 208 controls. We evaluated its psychometric properties using advanced statistical techniques, including Item Response Theory (IRT). STUDY RESULTS The Ethiopian Cognitive Assessment battery for Schizophrenia (ECAS) was developed from three different batteries. Participants reported tests were easy to complete, and the raters found them easy to administer. All tests had good inter-rater reliability, and the composite score had very high test-retest reliability (ICC = 0.91). One-factor structure better represented the data with excellent internal consistency (α = .81). ECAS significantly differentiated PWS from controls with 77% sensitivity and 62% specificity at a Z-score ≤0.12 cut-off value. IRT analysis suggested that the battery functions best among moderately impaired participants (difficulty between -0.06 and 0.66). CONCLUSIONS ECAS is a practical, tolerable, reliable, and valid assessment of cognition. ECAS can supplement current assessment tools in LAMICs for PWS and can be used to measure cognitive intervention outcomes.

Abstract
BACKGROUND Metacognition refers to appraising one's thoughts and behaviours. Deficits in metacognition are associated with psychosis-spectrum experiences, such as hallucinations and delusions, in both clinical and non-clinical populations. Assessments of metacognitive function and abilities in clinical populations often vary in administration duration, and subjectivity of scores. This study investigates associations between different measures of metacognition and their prediction of psychosis spectrum experiences using objective and self-report measures in a cross-sectional study of psychosis-spectrum disorder (PSD) participants and controls. METHOD Twenty-three individuals with PSD and forty-four controls were recruited online and completed in-the-moment objective ratings of metacognitive accuracy (meta-Dots Task), and retrospective self-report of metacognitive self-reflection (Beck Cognitive Insight Scale) and abilities (Metacognition Self-Assessment Scale). RESULTS There were group differences in self-reported metacognition, with PSD participants having lower scores of metacognitive ability, but no differences in self-reflectiveness or objective metacognitive accuracy. In the PSD group, only self-reported metacognitive ability was associated with and predicted distress about, and conviction in, delusional thoughts. CONCLUSIONS The findings demonstrate group differences in some self-reported, but not objective, measures of metacognition, and highlight that prediction of PSD experiences depends on the metacognitive construct being measured, and the type of measurement used.

Abstract
OBJECTIVE Cognitive remediation (CR) improves cognition and aids recovery in people with psychosis. An active therapist provides increased benefit, but CR training for therapists is not routinely available, so CR has limited scalability. This study describes the development and evaluation of the first online CR therapist training programme. METHODS An online CR training, based on expert and novice therapist consultations, was developed, and then pilot tested with novice trainees and changes made to produce the evaluation version. Feasibility, acceptability, and training benefits were assessed in a group of naïve UK NHS mental health professionals. Training engagement with a group of clinicians who accessed the programme for professional development was compared to those who paid fees. RESULTS Most mental health professionals finished training and passed the knowledge test, indicating that training enhanced clinicians' knowledge. Fee-paying trainees had significantly faster completion times and a higher proportion finished in the recommended time. Those who were successful at passing the knowledge questionnaire had significantly fewer years in practice. The majority were satisfied with the programme, felt they had made considerable progress and that training would allow them to begin practicing CR, and would recommend the training to colleagues. CONCLUSIONS This online CR training programme was feasible, acceptable to participants and showed benefits for clinicians. It improved knowledge even in the most junior of staff who have had less time to develop clinical know-how.

Abstract
BACKGROUND A substantial proportion of people with bipolar disorder (BD) experience persistent cognitive difficulties associated with impairments in psychosocial functioning and a poorer disorder course. Emerging evidence suggests that cognitive remediation (CR), a psychological intervention with established efficacy in people with schizophrenia, can also benefit people with BD. Following a proof-of-concept trial showing that CR is feasible and potentially beneficial for people with BD, we are conducting an adequately powered trial in euthymic people with BD to 1) determine whether an individual, therapist-supported, computerised CR can reduce cognitive difficulties and improve functional outcomes; and 2) explore how CR exerts its effects. METHODS CRiB2 is a two-arm, assessor-blind, multi-site, randomised controlled trial (RCT) comparing CR to treatment-as-usual (TAU). Participants are people with a diagnosis of BD, aged between 18 and 65, with no neurological or current substance use disorder, and currently euthymic. 250 participants will be recruited through primary, secondary, tertiary care, and the community. Participants will be block-randomised (1:1 ratio, stratified by site) to continue with their usual care (TAU) or receive a 12-week course of therapy and usual care (CR + TAU). The intervention comprises one-on-one CR sessions with a therapist supplemented with independent cognitive training for 30-40 h in total. Outcomes will be assessed at 13- and 25-weeks post-randomisation. Efficacy will be examined by intention-to-treat analyses estimating between-group differences in primary (i.e., psychosocial functioning at week 25 measured with the Functional Assessment Short Test) and secondary outcomes (i.e., measures of cognition, mood, patient-defined goals, and quality of life). Global cognition, metacognitive skills, affect fluctuation, and salivary cortisol levels will be evaluated as putative mechanisms of CR through mediation models. DISCUSSION This study will provide a robust evaluation of efficacy of CR in people with BD and examine the putative mechanisms by which this therapy works. The findings will contribute to determining the clinical utility of CR and potential mechanisms of action.

Abstract
Assessment of cognitive impairment in people with schizophrenia (PWS) is limited in low and middle-income countries due to lack of context-appropriate measures. This study aimed to select, adapt, and evaluate an interview-based cognitive tool for PWS in Ethiopia. The study was carried out in three phases. In the first phase, we followed a rigorous instrument selection procedure to select a tool for adaptation. We then applied a rigorous instrument adaption procedure, including interviews with 24 participants. Finally, we evaluated the psychometric properties of the adapted tool with 208 PWS and 208 matched controls. The Cognitive Assessment Interview was selected as the appropriate tool for adaptation. This tool is practical and tolerable, with short time of administration. We reported high inter-rater reliability and test-retest reliability for the adapted scale. One-factor structure better represented the data with excellent internal consistency. Weak but significant correlation with a performance-based battery was reported. At a cut-off value of > 13, the tool significantly differentiated PWS from controls (62 % sensitivity and 82 % specificity). Item Response Theory-based analysis showed that the tool gives much information among severely impaired participants. The findings show that the tool is reliable, valid, and practical in resource-scarce settings.

Abstract
Cognitive Remediation (CR) improves cognition and functioning but is implemented in a variety of ways (independent, group and one-to-one). There is no information on whether service users find these implementation methods acceptable or if their satisfaction influences CR outcomes. We used mixed participatory methods, including focus groups, to co-develop a CR satisfaction scale. This was refined using three psychometric criteria (Cronbach's alpha, item discrimination, test-retest agreement) to select items. Factor analysis explored potential substructures. The refined measure was used in structural equation joint modelling to evaluate whether satisfaction with CR is affected by implementation method and treatment engagement or influences recovery outcome, using data from a randomised controlled trial. Four themes (therapy hours, therapist, treatment effects, computer use) generated a 31-item Cognitive Remediation Satisfaction scale (CRS) that reduced to 18 Likert items, 2 binary and 2 open-ended questions following psychometric assessment. CRS had good internal consistency (Alpha = 0.814), test-retest reliability (r= 0.763), and concurrent validity using the Working Alliance Inventory (r = 0.56). A 2-factor solution divided items into therapy engagement and therapy effects. Satisfaction was not related to implementation method but was significantly associated with CR engagement. Therapy hours were significantly associated with recovery, but there was no direct effect of satisfaction on outcome. Although satisfaction is important to therapy engagement, it has no direct effect on outcome. CR therapy hours directly affect outcome irrespective of which implementation model is used, so measuring satisfaction early might help to identify those who are likely to disengage. The study has mixed methods design.

Abstract
BACKGROUND Currently there is no first-line treatment recommended for the negative symptoms of schizophrenia. Psychosocial and behavioural interventions are widely used to reduce the burden of negative symptoms. Meta-analytic studies have summarised the evidence for specific approaches but not compared evidence quality and benefit. AIM To review and evaluate the evidence from meta-analytic studies of psychosocial and behavioural interventions for the negative symptoms of schizophrenia. METHOD A systematic literature search was undertaken to identify all meta-analyses evaluating psychosocial and behavioural interventions reporting on negative symptom outcomes in people with schizophrenia. Data on intervention, study characteristics, acceptability and outcome were extracted. Risk of bias was evaluated. Results were summarised descriptively, and evidence ranked on methodological quality. RESULTS In total, 31 systematic reviews met the inclusion criteria evaluating the efficacy of negative symptom interventions on 33 141 participants. Exercise interventions showed effect sizes (reduction in negative symptoms) ranging from -0.59 to -0.24 and psychological interventions ranging from -0.65 to -0.04. Attrition ranged between 12% to 32%. Across the studies considered heterogeneity varied substantially (range 0-100). Most of the reviews were of very low to low methodological quality. Methodological quality ranking suggested that the effect size for cognitive remediation and exercise therapy may be more robust compared with other approaches. CONCLUSIONS Most of the interventions considered had a small-to-moderate effect size, good acceptability levels but very few had negative symptoms as the primary intervention target. To improve the confidence of these effect sizes being replicated in clinical settings future studies should minimise risk of bias.

Abstract
BACKGROUND AND HYPOTHESIS Cognitive remediation (CR) benefits cognition and functioning in psychosis but we do not know the optimal level of therapist contact, so we evaluated the potential benefits of different CR modes. STUDY DESIGN A multi-arm, multi-center, single-blinded, adaptive trial of therapist-supported CR. Participants from 11 NHS early intervention psychosis services were independently randomized to Independent, Group, One-to-One, or Treatment-as-usual (TAU). The primary outcome was functional recovery (Goal Attainment Scale [GAS]) at 15-weeks post randomization. Independent and TAU arms were closed after an interim analysis, and three informative contrasts tested (Group vs One-to-One, Independent vs TAU, Group + One-to-One vs TAU). Health economic analyses considered the cost per Quality Adjusted Life Year (QALY). All analyses used intention-to-treat principles. STUDY RESULTS We analyzed 377 participants (65 Independent, 134 Group, 112 One-to-One, 66 TAU). GAS did not differ for Group vs One-to-One: Cohen's d: 0.07, -0.25 to 0.40 95% CI, P = .655; Independent vs TAU: Cohen's d: 0.07, -0.41 to 0.55 95% CI, P = .777. GAS and the cognitive score improved for Group + One-to-One vs TAU favoring CR (GAS: Cohen's d: 0.57, 0.19-0.96 95% CI, P = .003; Cognitive score: Cohens d: 0.28, 0.07-0.48 95% CI, P = .008). The QALY costs were £4306 for Group vs TAU and £3170 for One-to-One vs TAU. Adverse events did not differ between treatment methods and no serious adverse events were related to treatment. CONCLUSIONS Both active therapist methods provided cost-effective treatment benefiting functional recovery in early psychosis and should be adopted within services. Some individuals benefited more than others so needs further investigation. TRIAL REGISTRATION ISRCTN14678860 https://doi.org/10.1186/ISRCTN14678860Now closed.

Abstract
Previously youth-orientated, UK early intervention in psychosis (EI) services expanded care in 2016 to adults of any age. To compare EI care offering, clinical characteristics, and potential benefits for under-35s and over-35s, an observational study considering anonymised data for users of London-based EI services between April 2016 and December 2019 was conducted. Descriptive statistics and between groups comparisons are reported. The analysis considered 692 service users (32.5% over-35). Over-35s were more likely to be female, of poorer physical health, with severer problems at intake (Health of the Nation Outcome Scale, HoNOS). Under-35s had poorer appointment attendance, required increased use of inpatient facilities, and demonstrated greater risks to themselves and others. At discharge, HoNOS ratings indicated improvements for both groups. Over-35s constitute a considerable proportion of EI service-users, their care may involve less crisis management, more recovery-oriented intervention and physical health needs consideration. Care offering should reflect these needs.

Abstract
BACKGROUND Bipolar disorder (BD) is associated with cognitive and functional difficulties, persistent beyond mood episodes. Cognitive remediation (CR) is a psychological therapy targeting cognitive and functioning difficulties. Recent evidence suggests that CR may enhance long-term functioning but transfer mechanisms on functional outcomes have not been explored. We aim to investigate whether and how cognitive gains after CR transfer to functional improvement. METHODS We considered data from a randomized controlled trial comparing CR (n = 40) to treatment-as-usual (TAU; n = 40) in euthymic people with BD. Treatment outcomes included individual cognitive domains and global cognition, psychosocial functioning, and goal attainment. Regression-based mediation and moderation modelling were used to assess whether and how post-treatment cognitive changes translate into functional improvement at follow-up, three months after treatment end. RESULTS Cognitive gains after CR transferred to functional changes three months later: improvement in post-treatment global cognition partially mediated the effect of CR on psychosocial functioning (standardized indirect effect: -0.23, 95% CI -0.51 to -0.04). Goal attainment was not significantly mediated by changes in cognition, but post-treatment cognitive performance moderated the effect of CR on the GAS at follow-up (interaction effect: 0.78, 95% CI 0.08-1.55). CONCLUSIONS Our findings suggest that cognitive improvements contribute to functional improvement but transfer mechanisms differ between psychosocial functioning and idiosyncratic recovery goals. Cognition accounted for only a proportion of the total CR effect on functional outcomes. Future studies should consider other variables, such as metacognition, that may drive the transfer of CR effects to functional outcomes.

Abstract
BACKGROUND Social cognition interventions have shown promise for improving social functioning in people with schizophrenia. However, it is unclear how changes in social cognition affect social functioning. This study evaluates the impact of a social cognition intervention (GRASP - GRoup trAining for Social skills in Psychosis) on social cognition and social functioning outcomes and explores how two mechanisms, affect and physiological arousal, may drive changes. METHOD A two-arm single blind (assessor) randomized pilot trial comparing GRASP plus treatment-as-usual (TAU) with TAU alone in people with a diagnosis of schizophrenia. Participants were assessed with measures of social cognition, social functioning, and symptoms. All participants undertook a week-long mobile health assessment (experience sampling method) measuring social behavior and affect and used a wearable device recording autonomic activity. Assessments were performed at baseline and at week 10. RESULTS Forty-eight participants were randomly allocated to the treatment or control condition. Individuals randomized to GRASP did not show improvements on experience sampled social behavior and social cognition measures compared to controls. However, participants in the GRASP group enjoyed social contact more and had lower levels of negative affect and higher levels of positive affect compared to controls. There was no evidence of autonomic changes (i.e., electrodermal activity) associated with social behavior resulting from the therapy. CONCLUSION Social cognition interventions may be helpful in improving the quality of social contacts in people with schizophrenia by decreasing negative affect. Increase in social behavior may require longer periods to be evident. Future studies should consider how social cognition interventions may alter qualitative aspects associated with social behavior.

Abstract
BACKGROUND Cognitive impairment is a core feature of schizophrenia, associated with poor functional outcomes. The course of cognitive function in the years following illness onset has remained a subject of debate, with a previous analysis finding no worsening, providing support for the neurodevelopmental model of schizophrenia. Since then, many more studies have reported on longitudinal cognitive performance in early psychosis, with some indicating deterioration, which does not align with this view. AIMS This study aims to quantitatively review the literature on the longitudinal trajectory of cognitive deficits in the years following psychosis onset, in comparison with healthy controls. It is the first to also synthesise longitudinal data on social cognition. METHOD Electronic databases ('PubMed', 'PsycInfo' and 'Scopus') were searched (to end September 2021). Meta-analyses of 25 longitudinal studies of cognition in early psychosis were conducted (1480 patients, 789 health controls). Unlike previous analyses, randomised controlled trials and those with multiple cognitive testing periods within the first year were excluded to minimise bias (PROSPERO, ID: CRD42021241525). RESULTS Small improvements were observed for global cognition (g = 0.25, 95% CI 0.17-0.33) and individual cognitive domains, but these were comparable with healthy controls and likely an artefact of practice effects. CONCLUSIONS There is no evidence of continued cognitive decline or improvement in the early years following psychosis onset, with a need for more studies over longer follow-up periods. Practice effects highlight the importance of including control samples in longitudinal and intervention studies. Further data are needed to evaluate the course of social cognition subdomains.

Abstract
BACKGROUND Negative symptoms are typically observed in people with schizophrenia and indicate a loss or reduction of normal function (e.g. reduced motivation and affect display). Despite obstructing people's recovery, intervention development has received limited attention. This study tests the feasibility and acceptability of a novel Virtual Reality Supported Therapy for the Negative Symptoms of Schizophrenia (V-NeST). METHOD A single (rater) blind randomised study with two conditions; V-NeST plus treatment as-usual (TAU) vs. TAU alone, recruiting people with schizophrenia experiencing debilitating negative symptoms. Assessment was at baseline and 3-month post-randomisation. The pre-specified primary outcome was participants' goal attainment, secondary outcomes were negative symptoms and functioning. The study assessed feasibility and acceptability parameters including recruitment, eligibility, treatment adherence and retention. Acceptability was also evaluated qualitatively using a post-therapy feedback interview. Explorative therapy effect on outcomes was estimated. RESULTS The study recruited to its pre-specified target of 30 participants (15 randomised to V-Nest). Two participants in each trial arm disengaged and did not complete the study. Therapy engagement for those randomised to V-NeST was appropriate and research procedures were feasible. The experience with therapy and VR was described as positive and useful. Preliminary analysis suggested the therapy may have a large effect on participants goals and a possible effect on negative symptoms. CONCLUSION V-NeST is a feasible and acceptable intervention. This therapy has the potential to support people with schizophrenia achieving their recovery goals and may reduce negative symptoms. The efficacy results need to be evaluated in an appropriately powered efficacy study.

Abstract
OBJECTIVES Cognitive Behavioural Therapy (CBT) is an effective psychological intervention for sleep difficulties and has been used successfully in individuals with psychosis. However, access is restricted due to lack of resources and staff training. Delivering CBT for sleep problems using smartphone technology may facilitate wider access. This study aimed to evaluate the feasibility, acceptability and potential usefulness of a guided, smartphone-based CBT intervention targeting sleep disturbance for individuals with psychosis. DESIGN Participants with psychosis spectrum diagnoses were recruited to a single-arm, uncontrolled study and engaged with the seven-module programme via smartphone app for six weeks with therapist support. METHOD Feasibility was assessed by rates of referral, recruitment and completion. Acceptability was assessed by app usage, a satisfaction questionnaire and qualitative analysis of participants' semi-structured interview. Pre- and post-intervention assessment of sleep, psychotic experiences, mood, well-being and functioning was conducted. Mean change confidence intervals were calculated and reported as an indication of usefulness. RESULTS Fourteen individuals consented to participation, and eleven completed the post-intervention assessment. On average, each participant engaged with 5.6 of 7 available modules. Qualitative feedback indicated the intervention was considered helpful and would be recommended to others. Suggested improvements to app design were provided by participants. Potential treatment benefits were observed for sleep difficulties, and all outcomes considered, except frequency of hallucinatory experiences. CONCLUSIONS It is feasible and acceptable to deliver therapist-guided CBT for sleep problems by smartphone app for individuals with psychosis. This method provides a low-intensity, accessible intervention, which could be offered more routinely. Further research to determine treatment efficacy is warranted.

Abstract
BACKGROUND Psychosis, even in its early stages, is associated with significant disability, causing it to be ranked ahead of paraplegia and blindness in those aged 18-35 in terms of years lived with disability. Current pharmacological and psychological interventions intervention have focused primarily on the reduction of positive symptoms (hallucinations and delusions), with little benefit to domains of psychosis such as cognitive difficulties and social and occupational functioning. METHODS/DESIGN The CReSt-R intervention trial is a single center, pilot randomised controlled study based at the National University of Ireland (NUI), Galway. The trial will recruit participants from four clinical sites with assessment and intervention completed by the primary NUI Galway team. The trial will explore the feasibility, acceptability, and effectiveness of a novel psychosocial intervention for early psychosis based on a combined cognitive remediation training and cognitive behavioural therapy approach focused on social recovery. Participants, aged 16-35 within the first 5 years of a diagnosed psychotic disorder, will be recruited from the Children and Adolescent Mental Health Service and the Adult Mental Health Services in the region. DISCUSSION Cognitive remediation training (for improving cognition) and social recovery focused cognitive behavioural therapy, have both separately demonstrated effectiveness. This trial will evaluate the feasibility, acceptability, and explore the efficacy of a treatment approach that combines both approaches as part of an integrated, multicomponent intervention. TRIAL REGISTRATION Cognitive Remediation & Social Recovery in Early Psychosis (CReSt-R): ClincialTrials.gov Identifier NCT04273685. Trial registered Feb 18th, 2020. Last updated April 14th, 2021.

Abstract
Background:
History of childhood maltreatment is recognized as an important risk factor for the development of mental health and cognitive difficulties. Cognitive difficulties are associated with impairments in everyday functioning in different domains such as school or work. To date, no study has evaluated the feasibility and acceptability of cognitive remediation therapy (CRT) with teenagers with a history of childhood maltreatment.
Objective:
The objective was to assess the acceptability and feasibility of the CIRCuiTS program for teenagers in youth protection services and to explore the preliminary effect on clinical and neuropsychological outcomes.
Methods:
Ten participants were first assessed with clinical and neuropsychological measures. They then received a mean of 16 CRT sessions with the CIRCuiTS program adapted for teenagers. The same measures as baseline were repeated directly after the end of treatment, as well as 3-months and 1-year post-treatment. Descriptive statistics were used to assess feasibility and acceptability, while the preliminary effect of CIRCuiTS was assessed with Reliable Change Indices (RCIs).
Results:
CIRCuiTS was considered as acceptable by both participants and therapists for the attractiveness of the program, its easiness of use and understanding and its cultural adaptability. However, the feasibility was limited with only 50% of participants having had completed CIRCuiTS. This was mostly explained by contextual factors. RCIs revealed significant improvements in several neuropsychological domains, as well as a decline in other domains.
Conclusion:
This pilot study highlights challenges that must be addressed to promote engagement to CRT for teenagers in the care of youth protection services.

Abstract
Stigma has negative effects on people with mental health problems by making them less likely to seek help. We develop a proof of principle service user supervised machine learning pipeline to identify stigmatising tweets reliably and understand the prevalence of public schizophrenia stigma on Twitter. A service user group advised on the machine learning model evaluation metric (fewest false negatives) and features for machine learning. We collected 13,313 public tweets on schizophrenia between January and May 2018. Two service user researchers manually identified stigma in 746 English tweets; 80% were used to train eight models, and 20% for testing. The two models with fewest false negatives were compared in two service user validation exercises, and the best model used to classify all extracted public English tweets. Tweets classed as stigmatising by service users were more negative in sentiment (t (744) = 12.02, p < 0.001 [95% CI: 0.196–0.273]). Our linear Support Vector Machine was the best performing model with fewest false negatives and higher service user validation. This model identified public stigma in 47% of English tweets (n5,676) which were more negative in sentiment (t (12,143) = 64.38, p < 0.001 [95% CI: 0.29–0.31]). Machine learning can identify stigmatising tweets at large scale, with service user involvement. Given the prevalence of stigma, there is an urgent need for education and online campaigns to reduce it. Machine learning can provide a real time metric on their success.

Abstract
Cognitive impairment is one of the core symptoms of schizophrenia. Quite a number of systematic reviews were published related to cognitive impairment in people with schizophrenia (PWS). This umbrella review, therefore, aimed at reviewing and synthesizing the findings of systematic reviews related to domains of cognition impaired and associated factors in PWS. We searched four electronic databases. Data related to domains, occurrence, and associated factors of cognitive impairment in PWS were extracted. The quality of all eligible systematic reviews was assessed using A MeaSurement Tool to Assess methodological quality of systematic Review (AMSTAR) tool. Results are summarized and presented in a narrative form. We identified 63 systematic reviews fulfilling the eligibility criteria. The included reviews showed that PWS had lower cognitive functioning compared to both healthy controls and people with affective disorders. Similar findings were reported among psychotropic free cases and people with first episode psychosis. Greater impairment of cognition was reported in processing speed, verbal memory, and working memory domains. Greater cognitive impairment was reported to be associated with worse functionality and poor insight. Cognitive impairment was also reported to be associated with childhood trauma and aggressive behaviour. According to our quality assessment, the majority of the reviews had moderate quality. We were able to find a good number of systematic reviews on cognitive impairment in PWS. The reviews showed that PWS had higher impairment in different cognitive domains compared to healthy controls and people with affective disorders. Impairment in domains of memory and processing speed were reported frequently.

Abstract
Severe mental illness (SMI) is associated with poor daily functioning; however available interventions currently under-deliver on their recovery prospect. Mobile digital health (mHealth) interventions are increasingly being developed and evaluated, and have the potential to support recovery. This review evaluates the use of mHealth technology to assess, monitor and reduce functioning difficulties in people with SMI. Studies were systematically searched on multiple databases. Study quality was assessed and double-rated independently. Findings were organised using a narrative synthesis and results were summarised according to the mHealth device purpose, i.e., assessment and monitoring or intervention. Thirty-eight studies comprised of 2262 participants met the inclusion criteria. Smartphones were the most popular mHealth device; personal digital assistants, wearables and tablets were also used. mHealth was widely found to be acceptable and feasible, with preliminary findings suggesting it can support functional recovery by augmenting an intervention, simplifying the assessment, increasing monitoring frequency and/or providing more detailed information. Considerations for overcoming barriers to implementation, recommendations for future research to establish effectiveness, personalisation and specification of mHealth devices and methodologies are discussed. The value of mHealth for remote delivery of recovery based interventions is also considered.

Abstract
BACKGROUND Functional impairment is a major target in the treatment of bipolar disorder (BD), but the magnitude and type of functional difficulties differ across patients. Findings on predictors of overall functioning and specific functional areas are inconsistent. We aimed to characterize functional difficulties and identify factors associated with global functioning and individual domains in euthymic patients. METHODS The Functional Assessment Short Test (FAST) was used to assess overall psychosocial functioning and specific functional domains in 80 euthymic participants with BD. Participants also completed a clinical interview and a cognitive assessment. Model selection with elastic net regression was performed to identify predictors of global functioning. We then examined the association of these predictors with individual functional domains using correlation. RESULTS FAST scores indicated moderate or severe impairment for 54% of the sample, with occupational functioning showing the highest impairment rate. Elastic net regression selected a model with three variables (higher residual depressive symptoms, lower executive functioning, more perceived cognitive deficits) as predictors of overall functioning. No significant associations were found between these predictors. Depressive symptoms were associated with interpersonal relationships and leisure time, executive skills with occupational functioning, and perceived deficits with cognitive functioning. CONCLUSIONS Residual depressive symptoms were the strongest predictor of overall functioning which highlights the importance of assessing and targeting subthreshold symptoms for recovery. Executive difficulties were associated with functioning, particularly occupational skills, independently of depressive symptoms. Interventions targeting these difficulties, such as cognitive and functional remediation, may be key treatment options towards facilitating functional recovery.

Abstract
Objectives Although cognitive dysfunction is a prominent feature of bipolar disorder (BD), previous research presents limitations in estimating the proportion of euthymic patients experiencing clinically relevant deficits and identifying predictors of cognitive difficulties. We explored the relevance of recommended definitions of clinically significant cognitive impairment for functional outcomes, estimated its prevalence, and identified patient characteristics associated with cognition. Methods We assessed cognitive performance across four domains in 80 euthymic participants with BD. Participants were categorized based on two criteria for clinically significant cognitive impairment and we assessed the ability of these criteria to differentiate participant performance on established functional outcomes. Variable selection with elastic net regression was used to identify sociodemographic and clinical factors associated with cognitive performance. Selected variables were examined as predictors of clinically significant cognitive impairment with logistic regression. Results According to the selected criterion, 34% presented with clinically significant cognitive impairment. Poorer current cognitive performance was associated with older age, lower estimated premorbid IQ, more currently prescribed psychotropic medications, fewer previous psychological therapies, and current use of antipsychotics. A model with premorbid IQ, psychotropic medications and previous psychological therapies as predictors of cognitive impairment correctly classified 75% of the participants. Conclusions This is one of the first studies to use a model selection approach to identify factors associated with cognitive difficulties in BD. Our findings offer the initial steps towards a predictive model for cognitive impairment. This could improve treatment decisions and prioritization for euthymic patients with BD, particularly the implementation of cognitive interventions.

Abstract
Hallucinatory experiences (HEs) can be pronounced in psychosis, but similar experiences also occur in nonclinical populations. Cognitive mechanisms hypothesized to underpin HEs include dysfunctional source monitoring, heightened signal detection, and impaired attentional processes. Using data from an international multisite study on non-clinical participants (N = 419), we described the overlap between two sets of variables - one measuring cognition and the other HEs - at the level of individual items. We used a three-step method to extract and examine item-specific signal, which is typically obscured when summary scores are analyzed using traditional methodologies. The three-step method involved: (1) constraining variance in cognition variables to that which is predictable from HE variables, followed by dimension reduction, (2) determining reliable HE items using split-halves and permutation tests, and (3) selecting cognition items for interpretation using a leave-one-out procedure followed by repetition of Steps 1 and 2. The results showed that the overlap between HEs and cognition variables can be conceptualized as bi-dimensional, with two distinct mechanisms emerging as candidates for separate pathways to the development of HEs: HEs involving perceptual distortions on one hand (including voices), underpinned by a low threshold for signal detection in cognition, and HEs involving sensory overload on the other hand, underpinned by reduced laterality in cognition. We propose that these two dimensions of HEs involving distortions/liberal signal detection, and sensation overload/reduced laterality may map onto psychosis-spectrum and dissociation-spectrum anomalous experiences, respectively.

Abstract
OBJECTIVES Evidence suggests social-cognitive difficulties are linked to poor community functioning in people with psychosis, however, there is limited evidence that social-cognition interventions improve functioning. This may be due to poor generalization of therapy learning; digital technologies may be useful to support this. This study evaluates the feasibility of a brief, blended intervention (group therapy plus app) for individuals with psychosis. METHODS A total of 14 clients diagnosed with psychosis-spectrum difficulties participated. Feasibility was assessed by referral, adherence and completion rates, and acceptability via semi-structured interview (thematically analyzed). RESULTS The procedures were considered feasible and acceptable. The face-to-face component of the intervention was particularly valued, and participants reported benefits to their daily lives. The app was experienced as helpful, alongside some difficulties. CONCLUSIONS Development of blended interventions may prove an important avenue to maximize the adherence and reach of psychological interventions. The results of this study reinforce the need to maintain face-to-face components alongside digital.

Abstract
Hallucinatory experiences can occur in both clinical and nonclinical groups. However, in previous studies of the general population, investigations of the cognitive mechanisms underlying hallucinatory experiences have yielded inconsistent results. We ran a large-scale preregistered multisite study, in which general-population participants (N = 1,394 across 11 data-collection sites and online) completed assessments of hallucinatory experiences, a measure of adverse childhood experiences, and four tasks: source memory, dichotic listening, backward digit span, and auditory signal detection. We found that hallucinatory experiences were associated with a higher false-alarm rate on the signal detection task and a greater number of reported adverse childhood experiences but not with any of the other cognitive measures employed. These findings are an important step in improving reproducibility in hallucinations research and suggest that the replicability of some findings regarding cognition in clinical samples needs to be investigated.

Abstract
BACKGROUND Evidence supports the use of group therapy for symptom reduction and improving functioning in people with psychosis. However, research guidelines highlight the importance of establishing the feasibility of interventions. Adherence is an important indicator of feasibility and an essential step in supporting the development of the evidence base for group interventions. This review aims to estimate adherence, and possible barriers and facilitators, to psychotherapeutic groups in people with psychosis. METHODS Embase, Ovid MEDLINE and PsycINFO databases were searched for cross-referencing terms related to group therapy and psychosis. Studies were assessed against inclusion criteria and methodological quality was evaluated. Data wasextracted from each paper including the average session attendance, demographic, clinical, study and therapy-related characteristics and the impact of these on adherence levels evaluated. RESULTS Fifty-nine original research papers were included, reporting on 52 independent studies which consisted of 66 therapy groups comprised of 2109 participants. Average adherence was 76.4% (s.d. = 17.4). Adherence was improved by receiving incentives and was higher in participants of older age. Study sample size was inversely associated with adherence levels. Study quality was variable with approximately 61.5% found to be at risk of bias. The results support the feasibility of group therapy and suggest that adherence in people with psychosis is not dissimilar to those for people experiencing common mental health difficulties. These findings, alongside efficacy evidence, support the use of group interventions in people with psychosis but also highlight the need for further high-quality research on the efficacy for these approaches.

Abstract
OBJECTIVES Cognitive remediation therapy (CRT) may benefit people with bipolar disorder type I and II for whom cognitive impairment is a major contributor to disability. Extensive research has demonstrated CRT to improve cognition and psychosocial functioning in people with different diagnoses, but randomised trials of evidenced therapy programmes are lacking for bipolar disorders. The Cognitive Remediation in Bipolar (CRiB) study aimed to determine whether an established CRT programme is feasible and acceptable for people with bipolar disorders. METHODS This proof-of-concept, single-blind randomised trial recruited participants aged 18-65 with bipolar disorder, not currently experiencing an episode. They were 1:1 block randomised to treatment-as-usual (TAU) with or without individual CRT for 12 weeks. The partly computerised CRT programme ("CIRCuiTS") was therapist-led and is evidence-based from trials in those with psychotic illnesses. Data were collected and analysed by investigators blinded to group allocation. The main outcomes (week 13 and 25) examined participant retention, intervention feasibility and putative effects of CRT on cognitive and psychosocial functioning via intention-to-treat analyses. TRIAL REGISTRATION ISRCTN ID32290525. RESULTS Sixty participants were recruited (02/2016-06/2018) and randomised to CRT (n = 29) or TAU (n = 31). Trial withdrawals were equivalent (CRT n = 2/29; TAU n = 5/31). CRT satisfaction indicated high acceptability. Intention-to-treat analyses (N = 60) demonstrated greater improvements for CRT- than TAU-randomised participants: at both week 13 and 25, CIRCuiTS participants showed larger improvements in the following domains (week 25 effect sizes reported here): IQ (SES = 0.71, 95% CI [0.29,1.13]), working memory (SES = 0.70, 95% CI [0.31,1.10]), executive function (SES = 0.93, 95% CI [0.33,1.54]), psychosocial functioning (SES = 0.49, 95% CI [0.18,0.80]) and goal attainment (SES = 2.02, 95% CI [0.89,3.14]). No serious adverse events were reported. CONCLUSIONS CRT is feasible for individuals with bipolar disorders and may enhance cognition and functioning. The reported effect sizes from this proof-of-concept trial encourage further investigation in a definitive trial.

Abstract
Prenatal exposure to glucocorticoids (GC) is a central topic of interest in medicine since GCs are essential for the maturation of fetal organs and intrauterine growth. Synthetic glucocorticoids, which are used in obstetric practice, exert beneficial effects on the fetus, but have also been reported to lead to intrauterine growth retardation (IUGR). In this study, a model of growth restriction in mice was established through maternal administration of dexamethasone during late gestation. We hypothesised that GC overexposure may adversely affect placental angiogenesis and fetal and placental growth. Female BALB/c mice were randomly assigned to control or dexamethasone treatment, either left to give birth or euthanised on days 15, 16, 17 and 18 of gestation followed by collection of maternal and fetal tissue. The IUGR rate increased to 100% in the dexamethasone group (8 mg/kg body weight on gestational days 14 and 15) and pups had clinical features of symmetrical IUGR at birth. Dexamethasone administration significantly decreased maternal body weight gain and serum corticosterone levels. Moreover, prenatal dexamethasone treatment not only induced fetal growth retardation but also decreased placental weight. In IUGR placentas, VEGFA protein levels and mRNA expression of VEGF receptors were reduced and NOS activity was lower. Maternal dexamethasone administration also reduced placental expression of the GC receptor, αGR. We demonstrated that maternal dexamethasone administration causes fetal and placental growth restriction. Furthermore, we propose that the growth retardation induced by prenatal GC overexposure may be caused, at least partially, by an altered placental angiogenic profile.

Abstract
BACKGROUND While Cognitive Remediation (CR) is effective in reducing cognitive and functioning difficulties in people with schizophrenia, there is variability in treatment response. Previous research suggested that participants' age may be a significant moderator of CR response. AIM To examine the impact of participants' age on CR outcomes. METHOD Individual participant data were accessed from fourteen CR randomised controlled trials. We tested the moderating effect of participants' age on cognitive and functioning outcomes using multivariate linear models. RESULTS Data from 1084 people with a diagnosis of schizophrenia were considered. Participants had a mean age of 36.6 years (SD 11), with 11.6 years of education (SD 2.8), and an average duration of illness of 13.5 years (SD 10.7). Multivariate models showed that participants' age, when considered as a continuous variable, was not a significant moderator of treatment effect for cognitive and functioning outcomes. However, when participants were split by median age, younger participants showed higher gains in executive functions following CR compared to older participants (p=0.02). CONCLUSION These results suggest that participants' age does not moderate most CR outcomes. However, larger age differences may influence the effect of CR on executive function. This may suggest some adaptation of CR practice according to participants' age. These findings inform the CR personalisation agenda.

Abstract
BACKGROUND IQ and IQ decline are considered risk factors for poor prognosis in people with a diagnosis of schizophrenia. However, it is still not clear if, at least in part, IQ and IQ decline influence long-term outcomes via a negative effect on interventions. AIM To identify whether current IQ, estimated premorbid IQ, or IQ decline moderate the response to cognitive remediation (CR). METHOD Individual participant data from twelve randomised controlled trials of CR were considered. Hierarchical and k-means analyses were carried out to identify different IQ clusters. The moderating effect of estimated premorbid IQ, current IQ, and different IQ clusters (preserved, deteriorated and compromised trajectories) on cognitive outcomes at post-therapy and follow-up were evaluated using multiple linear regression. RESULTS Data from 984 participants (CR = 544, control = 440) with schizophrenia and schizoaffective disorders were considered. The sample had a mean current IQ of 84.16 (SD 15.61) and estimated premorbid IQ of 95.82 (SD 10.63). Current IQ moderated working memory outcomes: people with higher IQ had larger working memory gains after therapy compared to those with a lower IQ. Those with a preserved IQ had better cognitive outcomes compared to either the deteriorated or compromised IQ groups, and those with a deteriorated IQ had better outcomes compared to those in the compromised IQ group. CONCLUSION Current IQ is a significant moderator of cognitive gains after CR. These findings highlight the need to evaluate whether therapy adaptations (e.g. offering more sessions) can attenuate this effect so that those with lower IQ may derive benefit similar to those with higher IQ.

Abstract
BACKGROUND People with bipolar disorder have moderate cognitive difficulties that tend to be more pronounced during mood episodes but persist after clinical remission and affect recovery. Recent evidence suggests heterogeneity in these difficulties, but the factors underlying cognitive heterogeneity are unclear. AIMS To examine whether distinct cognitive profiles can be identified in a sample of euthymic individuals with bipolar disorder and examine potential differences between subgroups. METHOD Cognitive performance was assessed across four domains (i.e. processing speed, verbal learning/memory, working memory, executive functioning) in 80 participants. We conducted a hierarchical cluster analysis and a discriminant function analysis to identify cognitive profiles and considered differences in cognitive reserve, estimated cognitive decline from premorbid cognitive functioning, and clinical characteristics among subgroups. RESULTS Four discrete cognitive profiles were identified: cognitively intact (n = 25; 31.3%); selective deficits in verbal learning and memory (n = 15; 18.8%); intermediate deficits across all cognitive domains (n = 30; 37.5%); and severe deficits across all domains (n = 10; 12.5%). Cognitive decline after illness onset was greater for the intermediate and severe subgroups. Cognitive reserve scores were increasingly lower for subgroups with greater impairments. A smaller proportion of cognitively intact participants were using antipsychotic medications compared with all other subgroups. CONCLUSIONS Our findings suggest that individuals with cognitively impaired profiles demonstrate more cognitive decline after illness onset. Cognitive reserve may be one of the factors underlying cognitive variability across people with bipolar disorder. Patients in the intermediate and severe subgroups may be in greater need of interventions targeting cognitive difficulties.

Abstract
Abstract
Background
In Italy almost one in 10 people eat a meal in collective catering (CC) every day.
The WHO and FAO emphasize the need to guarantee adequate amounts of antioxidants and protective phytochemicals, essential for the many metabolic functions, by intake of minimally processed foods. It is strategic to ensure protective meals for all CC users, especially hospital patients and the elderly. Recently the Public Procurement (PP) have more often chosen Cook & Chill (C&C) systems, characterized by the administration of meals stored between 0 and +3 C ° for 20 - 30 days. The aims of the project were to: evaluate the qualitative - quantitative profile of the effective protective molecules in C&C meals, determine any nutritional critical points (NCPs) - corrective actions (CAs) of C&C, identify rapid and cheap methods for monitoring the nutritional quality of meals and identify portable systems easy to use by non-professional operators in the chemical-analytical sector.
Methods
The NACCP process indicated by the Ministry of Health has been applied. In 2019 over 120 foods collected at different stages of the production of a C&C were sampled. The University of Trieste has performed over 850 analyses. The outcomes were compared with the food composition database by the agency of the Ministry of Agriculture (MA).
Results
The quantitative profile of the protective molecules present in C&C meals was in many cases reduced by 15 to 75% compared to the MA database. The protective capacity of some meals administered is comparable to that of ultra-processed food. The NCPs - CAs have been determined to ensure an adequate content of protective compounds in C&C meals. Rapid screening systems with chromatographic and optical techniques were identified. Portable systems with immediate analytical response will be developed.
Conclusions
The results of the project can significantly orient PP towards choices that: adhere to the WHO recommendations and adopt nutritional quality monitoring tools.
Key messages
Include nutritional quality criteria for choosing collective catering systems. Monitor the nutritional quality of collective catering through rapid screening systems.

Abstract
WHAT IS KNOWN ON THE SUBJECT?: To date, improvements on U.K. acute mental health wards have been difficult to sustain. The barriers to change may be context dependent. Mental health wards are volatile workplaces with service user violence/aggression, frequent staff and patient changes, and ongoing service improvements. The evidence suggests that burnout affects staff perceptions of barriers to change, and ward climate affects burnout. As two potentially important, independent predictors of staff perceptions of barriers to change, the impact of ward climate and burnout on how staff regard changes should be considered. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Elements of ward climate such as high numbers of incidents and temporary staff independently worsened mental health staff perceptions of barriers to change, in addition to negative impacts from burnout and occupational status. How staff perceived ward climate was also linked their perceptions of barriers to change; however, burnout was no longer a significant consideration with these variables. Staff with low job satisfaction and high interaction anxiety also had low confidence regarding changes. Staff with low job satisfaction were also demotivated towards changes. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Ward climate is clearly an important factor in how nurses view organizational changes. In this study, nurses' perceptions of barriers to change were worse if they viewed ward climate negatively, or if temporary staff and incident numbers were high. Staff perceptions of ward climate and barriers to change should be assessed, ahead of service changes. Developing change strategies based on such information is likely to produce better implementation outcomes. Specifically, targeting staff confidence and motivation (which are barriers to change) may improve how staff regard their ward climate. Abstract Introduction To create successful change programmes for mental health wards, it is necessary to understand which aspects of ward climate prevent change. Question Does ward climate influence mental health nurse's perceptions of barriers to change? Method Random-effects models were used to test whether the following ward climate variables influenced the outcome measure "staff perceptions of barriers to change" (VOCALISE) and its subscales (powerlessness/confidence/demotivation): (a) Perceptions of ward climate (VOTE: subscales included work intensity/job satisfaction/interaction anxiety). (b) Ward climate indicators (incidents/detention under the Mental Health Act (2007)/staffing/bed pressure). As known predictors of VOCALISE, burnout (Maslach Burnout Inventory) and occupational status were included in the models. Results Perceptions of ward climate (VOTE), incidents, temporary staff, occupational status and burnout significantly and negatively affected perceptions of barriers to change (VOCALISE). Staff with low job satisfaction (VOTE) and high interaction anxiety (VOTE) also had low confidence (VOCALISE). Staff with low job satisfaction (VOTE) were also demotivated (VOCALISE). Discussion Ward climate is an important predictor of how staff regard service changes in mental health wards. Implications for practice Staff perceptions of ward climate and barriers to change should be assessed ahead of service changes to identify pressures that impede progress and lower morale.

Abstract
BACKGROUND Patients with bipolar disorder (BD) suffer from cognitive deficits across several domains. The association between cognitive performance and psychosocial functioning has led to the emergence of cognition as a treatment target. OBJECTIVE This study reviews the existing literature on cognitive enhancement interventions for people with BD, focusing on different treatment approaches and methodological quality. METHODS We conducted a systematic search following the PRISMA guidelines. Sample characteristics and main outcomes for each study and treatment characteristics for each approach were extracted. Study quality was assessed using the Clinical Trials Assessment Measure (CTAM) and Cochrane Collaboration's Risk of Bias tool by independent raters. RESULTS Eleven articles reporting data from seven original studies were identified encompassing 471 participants. Two treatment approaches were identified, cognitive and functional remediation. For controlled studies, methodological quality was modest (average CTAM score = 60.3), while the overall risk of bias was considered moderate. Beneficial effects on cognitive or functional outcomes were reported in the majority of studies (91%), but these findings were isolated and not replicated across studies. Key methodological limitations included small sample sizes, poor description of randomization process, high attrition rates, and participant exclusion from the analysis. CONCLUSIONS Findings are promising but preliminary. Quality studies were few and mostly underpowered. Heterogeneity in sample characteristics, outcome measures, and treatment approaches further limit the ability to generalize findings. Adequately powered trials are required to replicate initial findings, while moderators of treatment response and mechanisms of transfer need to be explored.

Abstract
Background: Cognitive difficulties are a core deficit for people with schizophrenia and are generally assessed with neuropsychological tests. Self-report assessments are also useful in understanding difficulties from the service user's perspective. This study aims to introduce and test the shorter version of the Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS) to improve its acceptability and comprehensibility.Methods: In consultation with service users and clinicians, we identified items from the original 21-item SSTICS that were found difficult and these were excluded. The reduced scale was explored with Confirmatory Factor Analysis (CFA) in two independent samples in the UK and Canada. Convergent validity with symptoms and IQ was assessed and compared between the original and the reduced scale.Results: Six-hundred and seven people with schizophrenia and first-episode psychosis took part in this study. Seven items were removed to produce the SSTICS-Brief. This had good reliability and the CFA confirmed a unidimensional structure. Convergent validity with symptoms and IQ were optimal between the long and short versions.Conclusions: The SSTICS-B has better acceptability than its longer form and could be administered in less time. The resulting measure is likely to be a valuable short self-assessment of cognitive complaints for people with schizophrenia.

Abstract
Cognitive difficulties are common in people with psychosis and associated with considerable disability. Cognitive remediation (CR) can reduce the burden of cognitive difficulties and improve functioning. While mental health care has predominantly shifted to the community, people with greater illness severity and complexity, and those with poor response to treatment and concomitant greater cognitive difficulties, continue to receive inpatient care. The aim of this study is to review and evaluate the acceptability and efficacy of CR for inpatients with psychosis. A systematic search was used to identify randomized controlled trials of CR for inpatients with psychosis. Demographic and clinical information was extracted by independent raters together with therapy outcomes. Study quality was assessed using the Cochrane Collaboration Risk of Bias Assessment tool. Standardized mean change for cognitive and functional outcomes was calculated using Hedges's g and used to infer therapy effects with meta-analysis. Twenty studies were identified considering 1509 participants. Results from random-effect models suggested that CR was effective in improving processing speed (g = 0.48), memory (g = 0.48) and working memory (g = 0.56). While there was an indication of improvements in the levels of vocational, social and global functioning, these were less reliable. On average, 7% of participants dropped-out of treatment. Studies methodological quality was moderate. CR is an acceptable intervention for inpatients with psychosis and can lead to significant cognitive improvements. Evidence for improvement in functioning requires more robust and converging evidence. Future research should extend the evaluation of inpatient CR to subsequent post-discharge community functioning and further need for care.

Abstract
BACKGROUND Staff and service users have expressed concerns that service improvements in British mental health wards have been slow or transient. It is possible that certain changes are positive for some (e.g. service users), but negative for others (e.g. staff), which may affect implementation success. In this study, we explore whether a programme of change to improve the therapeutic milieu on mental health wards influenced staff perceptions of barriers to change, 12 months after implementation. METHOD A cluster randomised controlled trial called DOORWAYS was conducted on eight British, inner-city acute mental health wards. Randomisation was achieved using a list randomly generated by a computer. A psychologist trained ward staff (mainly nurses) to deliver evidence-based groups and supported their initial implementation. The impact of these changes was measured over 12 months (when 4 wards were randomised), according to nurses' perceptions of barriers to change (VOCALISE), using unstructured multivariate linear regression models. This innovative analysis method allows maximum use of data in randomised controlled trials with reduced sample sizes due to substantial drop out rates. The contextual influences of occupational status (staff) and of workplace setting (ward) were also considered. RESULTS Staff who participated in the intervention had significantly worse perceptions of barriers to change at follow up. The perceptions of staff in the control group did not change over time. In both groups (N = 120), direct care staff had more negative perceptions of barriers to change, and perceptions varied according to ward. Across time, direct care staff in the intervention group became more negative than those in the control group. CONCLUSION Participation in this program of change, worsened staff perceptions of barriers to change. In addition, occupational status (being from the direct care group) had a negative effect on perceptions of barriers to change, an effect that continued across time and was worse in the intervention group. Those providing direct care should be offered extra support when changes are introduced and through the implementation process. More effort should be placed around reducing the perceived burden of innovation for staff in mental health wards. TRIAL REGISTRATION ISRCTN, ISRCTN 06545047.

Abstract
Abstract
Surveys (2008-2018) carried out by the Local Health Agency of Trieste (ASUITS) in local collective catering (CC) services of schools, hospitals, nursing homes, and workplaces (25.000 daily meals) have shown some non - adherence to healthier food choices, food standards, procedures and green and social procurement as recommended by the WHO, FAO, UE, Ministry of Health and of Environment.
The purpose of this project is to support local public and private organizations in transforming the national and regional catering services food standards related to health, nutrition, environment and social criteria into food procurement and food contracts specifications. This has been done by compiling the major obstacles to improved standards observed during surveys, and by sharing critical and relevant examples with major public contractors across local, regional and national level.
The guidelines (GL) for public procurement of CC consist of five chapters: the elaboration of specifications; a response module to present the offer of services; selection and award criteria, an evaluation system of offers, and the technical specifications attached. Technical information fixes the constituent elements of the service in order to have similar and directly comparable offers. GL cover both the purchasing of food and the contracting of catering services. In this way public or private institutions are able to prepare tender documents suitable to respond to health, economic needs and Sustainable Development Goals (SDGs).
The development of the GL has increased the awareness and real potential that local organizations have in enhancing the strategic use of purchasers to boost food qualification, jobs, growth and investment. As well as to create a more innovative economy, to be resource and energy efficient, and to be socially-inclusive.
To meet population nutrient intake goals and SDGs it is necessary to increase co-operation and the sharing of the objectives of ’Health in All Policies’.
Key messages
Contractors need practical tools to apply sustainable development goals criteria in collective catering. The integrated collective catering guide is a key to improving capacity building in institutions.

Abstract
Abstract
According to the literature the prevalence of the risk of malnutrition o hospitalized people exceeds 25% of patients, this evidence is also related to low meal satisfaction. To reduce hospital malnutrition it is also important to improve the consumption of meals by implementing organoleptic and nutritional quality (O&NQ).
The Local Health Agency of Trieste (ASUITS) has conducted surveys to find out how to evaluate and improve the procurement qualifications of hospital catering systems (HCS) and how to implement O&NQ. The production processes of meals served in two clinics using Cook Chill (CC) and Cook/Fresh - Hot Hold (CFHH) production process, respectively, were evaluated from 2017 - 2019. The Nutrient Analysis Critical Control Point process was applied for the evaluation of two catering systems. In addition, the antiradicalic power (ARP) of 120 samples of meals by the University of Trieste was analysed. In 2019 an investigation was conducted to compare the satisfaction and ARP content of meals served to patients in two hospital wards (N = 60). The meals to patients of two wards respectively with CC Cold Plating Retherm (PR) and CC Hot PR were served.
Meals produced by the CC production process highlight the average loss of 50% of ARP compared to the CFHH. Meals produced by the CC Cold PR method limit the loss of ARP by 15-40% less compared to the CC Hot PR method. The satisfaction of patients who have consumed meals produced by the CC Cold PR method is double compared to that of patients who have consumed meals produced by the CC Hot PR method. The surveys have produced significant evidence to evaluate hospital meal production processes and to improve O&NQ. The results were used to develop recommendations for the drafting of tender specifications capable of also protecting nutritional variables.
The evaluation of the O&NQ of HCS represents a central determinant of food safety and nutrition security and must be taken into consideration in the procurements procedure.
Key messages
Hospital catering contracts must evaluate and guarantee organoleptic and nutritional quality. Integrated evaluation of organoleptic and nutritional quality is an integral part of hospital meals.
