Abstract
BACKGROUND AND HYPOTHESIS Individuals with schizophrenia (SZ) and bipolar disorder (BD) show disruptions in self-referential gaze perception-a social perceptual process related to symptoms and functioning. However, our current mechanistic understanding of these dysfunctions and relationships is imprecise. STUDY DESIGN The present study used mathematical modeling to uncover cognitive processes driving gaze perception abnormalities in SZ and BD, and how they relate to cognition, symptoms, and social functioning. We modeled the behavior of 28 SZ, 38 BD, and 34 controls (HC) in a self-referential gaze perception task using drift-diffusion models parameterized to index key cognitive components: drift rate (evidence accumulation efficiency), drift bias (perceptual bias), start point (expectation bias), threshold separation (response caution), and nondecision time (encoding/motor processes). STUDY RESULTS Results revealed that aberrant gaze perception in SZ and BD was driven by less efficient evidence accumulation, perceptual biases predisposing self-referential responses, and greater caution (SZ only). Across SZ and HC, poorer social functioning was related to greater expectation biases. Within SZ, perceptual and expectancy biases were associated with hallucination and delusion severity, respectively. CONCLUSIONS These findings indicate that diminished evidence accumulation and perceptual biases may underlie altered gaze perception in patients and that SZ may engage in compensatory cautiousness, sacrificing response speed to preserve accuracy. Moreover, biases at the belief and perceptual levels may relate to symptoms and functioning. Computational modeling can, therefore, be used to achieve a more nuanced, cognitive process-level understanding of the mechanisms of social cognitive difficulties, including gaze perception, in individuals with SZ and BD.

Abstract
Background: Individuals with schizophrenia often exhibit social interaction deficits, which can affect their ability to engage effectively with others. Emotional processes, such as emotional contagion (the transfer of emotion between individuals) and emotional mimicry (the imitation of emotional expressions), are crucial for enhancing the quality of social interactions. Methods: We conducted a PubMed, Web of Science, and PsycInfo database search. The inclusion and exclusion criteria were established based on the definitions of emotional contagion and emotional mimicry, rather than relying on specific terminology from various research fields. Forty-two studies were included in the review, including six emotional mimicry studies and thirty-six emotional contagion studies. Results: The current findings suggest decreased or inappropriate emotional mimicry in individuals with schizophrenia. Relating to emotional contagion, the results showed altered brain and psychophysiological activity in individuals with schizophrenia, whereas the self-reported measures indicated no difference between the groups. The relationships between emotional contagion, emotional mimicry, and psychotic symptom severity showed variability across the studies, whereas no associations between antipsychotic dosage and either emotional mimicry or emotional contagion were found. Discussion: This review highlights the need to further evaluate and train emotional contagion and emotional mimicry in individuals with schizophrenia because these processess influence social interaction quality. Clinical implications and guidelines for future studies are discussed.

Abstract
Serotonin signaling plays critical roles in social and emotional behaviors. Likewise, decades of research demonstrate that the amygdala is a prime modulator of social behavior. Permanent excitotoxic lesions and transient amygdala inactivation consistently increase social behaviors in non-human primates. In rodents, acute systemic administration of drugs that increase serotonin signaling is associated with decreased social interactions. However, in primates, the direct involvement of serotonin signaling in the amygdala, particularly in affiliative social interaction, remains unexplored. Here, we examined the effects of serotonin manipulations within the amygdala on social behavior in eight pairs of familiar male macaques. We microinfused drugs targeting the serotonin system into either the basolateral (BLA) or central (CeA) amygdala and measured changes in social behavior. Surprisingly, the results demonstrated no significant differences in social behavior following the infusion of a selective serotonin reuptake inhibitor, 5-HT1A agonist or antagonist, 5-HT2A agonist or antagonist, or 5-HT3 agonist or antagonist into either the BLA or CeA. These findings suggest that serotonin signaling in the amygdala does not directly contribute to the regulation of social behavior between familiar conspecifics. Future research should explore alternative mechanisms and potential interactions with other brain regions to gain a comprehensive understanding of the complex neural circuitry governing social behavior.

Abstract
PURPOSE This clinical focus article aims to provide a comprehensive overview of schizophrenia and understanding of communication disorders resulting from its psychopathology. Schizophrenia is a spectrum disorder with varying levels of symptom expression. It is characterized by positive and negative symptoms that can cause communication disorders of different severity levels. Communication difficulties manifest as a range of symptoms such as alogia, disorganized speech, and impaired social communication. These challenges may result in receptive and expressive language deficits that lead to misunderstandings, reduced social interactions, and difficulties expressing thoughts and emotions effectively. The purpose of this clinical focus article is to explore the role of the speech-language pathologist (SLP) in assessing and treating communication disorders presented in schizophrenia. CONCLUSIONS In order to understand the role of the SLP in assessing and treating communication disorders in schizophrenia, it is imperative to understand the overall course, etiology, assessment, and treatment consideration of this condition. SLPs can provide services in the areas of social skills training and community-based intervention contexts.

Abstract
Affiliation is both an antecedent and a consequence of emotional mimicry (i.e. imitating a counterpart's emotional expression). Thus, interacting with a disliked partner can decrease emotional mimicry, which in turn can further decrease liking. This perpetuating circle has not been investigated in the context of mental health stigma yet. The present study tested the influence of the label "schizophrenia" on liking, interpersonal closeness, and emotional mimicry. In an online experiment (n = 201), participants recruited from the general population saw several videos of actors displaying emotional expressions. Actors were described with one of four labels: "schizophrenia", "healthy", "diabetes", and a negative adjective (e.g. "hot-tempered"). Emotional mimicry was measured using OpenFace 2.2. Liking and interpersonal closeness were assessed with questionnaires. Overall, compared to other labels, participants reported less liking and interpersonal closeness to the actor with the schizophrenia label. However, no effect on emotional mimicry was found. The decreased liking of the schizophrenia actors was explained by a lack of knowledge about schizophrenia and the explicit stigma of schizophrenia. Our study contributes to the literature by highlighting the need to reduce the stigma of schizophrenia.

Abstract
BACKGROUND Psychosis spectrum disorders are characterized by significant alterations in social functioning, which is a major factor for patient recovery. Despite its importance, objectively quantifying the complex day-to-day social behavior in real-life settings has rarely been attempted. Here, we conducted a pilot study with wearable sensors that passively and continuously register interactions with other participants. We hypothesized that the amount and pattern of social interaction was associated with the severity of psychotic symptoms. STUDY DESIGN We recruited 7 patients with psychosis spectrum disorders and 18 team members from a Soteria-style ward. Each participant wore a radio frequency identification badge, sending and receiving signals from nearby badges, allowing passive quantification of social interactions. In addition, symptom severity was assessed weekly by the Positive and Negative Syndrome Scale (PANSS). STUDY RESULTS During an 11-week period, we identified 17 970 interactions among patients and staff. On average, patients spent 2.6 h per day interacting, capturing relevant aspects of daily social life. Relative daily interaction time, average interaction duration, and clustering coefficient, a measure of local network integration, were significantly associated with lower PANSS scores. Self-reported interaction time did not correlate with measured interaction time or with PANSS, indicating the importance of objective markers. CONCLUSIONS This pilot study demonstrates the feasibility of passively recording social interaction of patients and staff at high resolution and for a long observation period in a real-life setting in a psychiatric department. We show links between quantified social interaction and psychopathology that may facilitate development and personalization of targeted treatments.

Financial dissatisfaction in people with psychotic disorders - A short report on its prevalence and correlates in a large naturalistic psychosis cohort. J Psychiatr Res 2024; 170:302-306.

Abstract
Psychotic disorders have a strong negative impact on multiple aspects of daily life, including people's financial situation. This exploratory study examines the level of financial dissatisfaction and its correlates in a large cohort of people with psychotic disorders. Data from the first assessments of people with psychotic disorders (n = 5271) who were included in the Pharmacotherapy Monitoring and Outcome Survey (PHAMOUS; 2006-2020), which is conducted in the northern Netherlands, were used. The Manchester Short Assessment of Quality of Life (MANSA) was used to measure financial dissatisfaction. In addition, sociodemographic and psychiatric characteristics, substance use and global and social functioning were assessed. One-fifth to one-third of people with psychotic disorders report financial dissatisfaction, fluctuating over the year in which they were assessed. These proportions are considerably higher than in the general population. Cannabis and other substance use were associated with higher levels of financial dissatisfaction (small to medium effect). The other significant associations showed (very) small effect sizes. Therefore, we conclude that financial dissatisfaction in people with psychotic disorders appears to be relatively independent of other demographic and psychiatric characteristics, and global and social functioning. These findings are an important first step for increasing knowledge on financial dissatisfaction among people with psychotic disorders. The findings can also contribute to raising awareness about the topic for healthcare professionals working in this field.

Abstract
INTRODUCTION The confidence of young people diagnosed with psychosis is often low. Positive self-beliefs may be few and negative self-beliefs many. A sense of defeat and failure is common. Young people often withdraw from many aspects of everyday life. Psychological well-being is lowered. Psychological techniques can improve self-confidence, but a shortage of therapists means that very few patients ever receive such help. Virtual reality (VR) offers a potential route out of this impasse. By including a virtual coach, treatment can be automated. As such, delivery of effective therapy is no longer reliant on the availability of therapists. With young people with lived experience, we have developed a staff-assisted automated VR therapy to improve positive self-beliefs (Phoenix). The treatment is based on established cognitive behavioural therapy and positive psychology techniques. A case series indicates that this approach may lead to large improvements in positive self-beliefs and psychological well-being. We now aim to conduct the first randomised controlled evaluation of Phoenix VR. METHODS AND ANALYSIS 80 patients with psychosis, aged between 16 and 30 years old and with low levels of positive self-beliefs, will be recruited from National Health Service (NHS) secondary care services. They will be randomised (1:1) to the Phoenix VR self-confidence therapy added to treatment as usual or treatment as usual. Assessments will be conducted at 0, 6 (post-treatment) and 12 weeks by a researcher blind to allocation. The primary outcome is positive self-beliefs at 6 weeks rated with the Oxford Positive Self Scale. The secondary outcomes are psychiatric symptoms, activity levels and quality of life. All main analyses will be intention to treat. ETHICS AND DISSEMINATION The trial has received ethical approval from the NHS Health Research Authority (22/LO/0273). A key output will be a high-quality VR treatment for patients to improve self-confidence and psychological well-being. TRIAL REGISTRATION NUMBER ISRCTN10250113.

Abstract
Autism (ASD) and schizophrenia spectrum disorders (SCZ) are neurodevelopmental conditions with overlapping and interrelated symptoms. A network analysis approach that represents clinical conditions as a set of "nodes" (symptoms) connected by "edges" (relations among symptoms) was used to compare symptom organization in the two conditions. Gaussian graphical models were estimated using Bayesian methods to model separate symptom networks for adults with confirmed ASD or SCZ diagnoses. Though overall symptom organization differed by diagnostic group, both symptom networks demonstrated high centrality of social communication difficulties. Autism-relevant restricted and repetitive behaviors and schizophrenia-related cognitive-perceptual symptoms were uniquely central to the ASD and SCZ networks, respectively. Results offer recommendations to improve differential diagnosis and highlight potential treatment targets in ASD and SCZ.

Abstract
Background Over the past 10 years, job interview training has emerged as an area of study among adults with schizophrenia and other serious mental illnesses who face significant challenges when navigating job interviews. The field of mental health services research has limited access to assessments of job interview skills with rigorously evaluated psychometric properties. Objective We sought to evaluate the initial psychometric properties of a measure assessing job interview skills via role-play performance. Methods As part of a randomized controlled trial, 90 adults with schizophrenia or other serious mental illnesses completed a job interview role-play assessment with eight items (and scored using anchors) called the mock interview rating scale (MIRS). A classical test theory analysis was conducted including confirmatory factor analyses, Rasch model analysis and calibration, and differential item functioning; along with inter-rater, internal consistency, and test-retest reliabilities. Pearson correlations were used to evaluate construct, convergent, divergent, criterion, and predictive validity by correlating the MIRS with demographic, clinical, cognitive, work history measures, and employment outcomes. Results Our analyses resulted in the removal of a single item (sounding honest) and yielded a unidimensional total score measurement with support for its inter-rater reliability, internal consistency, and test-retest reliability. There was initial support for the construct, convergent, criterion, and predictive validities of the MIRS, as it correlated with measures of social competence, neurocognition, valuing job interview training, and employment outcomes. Meanwhile, the lack of correlations with race, physical health, and substance abuse lent support for divergent validity. Conclusion This study presents initial evidence that the seven-item version of the MIRS has acceptable psychometric properties supporting its use to assess job interview skills reliably and validly among adults with schizophrenia and other serious mental illnesses.

Maternal immune activation as an epidemiological risk factor for neurodevelopmental disorders: Considerations of timing, severity, individual differences, and sex in human and rodent studies. Front Neurosci 2023; 17:1135559. [PMID: 37123361 PMCID: PMC10133487 DOI: 10.3389/fnins.2023.1135559] [Citation(s) in RCA: 19] [Impact Index Per Article: 19.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Accepted: 03/13/2023] [Indexed: 05/02/2023] Open
Abstract
Epidemiological evidence suggests that one's risk of being diagnosed with a neurodevelopmental disorder (NDD)-such as autism, ADHD, or schizophrenia-increases significantly if their mother had a viral or bacterial infection during the first or second trimester of pregnancy. Despite this well-known data, little is known about how developing neural systems are perturbed by events such as early-life immune activation. One theory is that the maternal immune response disrupts neural processes important for typical fetal and postnatal development, which can subsequently result in specific and overlapping behavioral phenotypes in offspring, characteristic of NDDs. As such, rodent models of maternal immune activation (MIA) have been useful in elucidating neural mechanisms that may become dysregulated by MIA. This review will start with an up-to-date and in-depth, critical summary of epidemiological data in humans, examining the association between different types of MIA and NDD outcomes in offspring. Thereafter, we will summarize common rodent models of MIA and discuss their relevance to the human epidemiological data. Finally, we will highlight other factors that may interact with or impact MIA and its associated risk for NDDs, and emphasize the importance for researchers to consider these when designing future human and rodent studies. These points to consider include: the sex of the offspring, the developmental timing of the immune challenge, and other factors that may contribute to individual variability in neural and behavioral responses to MIA, such as genetics, parental age, the gut microbiome, prenatal stress, and placental buffering.

Abstract
Social functioning deficits during adolescence are associated with later psychiatric morbidity, particularly in offspring at high genetic risk for schizophrenia spectrum disorders. However, a shortcoming of earlier study findings is the lack of control of the impact of the family rearing environment. The study was aimed to examine the association of adoptees' social functioning during adolescence, adoptive family functioning, and adoptees' high (HR) or low (LR) genetic risk for schizophrenia spectrum disorders with adoptees' later psychiatric morbidity. The present subsample from the nationwide Finnish Adoptive Family Study of Schizophrenia included 57 HR and 60 LR adoptees. Adolescent social functioning was assessed using UCLA Social Attainment Survey (UCLA SAS). Adoptive family functioning was based on Global Family Ratings (GFRs) and psychiatric disorders on DSM-III-R criteria. The results indicated that, after controlling for adoptive family functioning and genetic risk for schizophrenia spectrum disorders, deficits in peer relationships during adolescence were associated with an increased likelihood of psychiatric morbidity of adoptees. Our findings highlight social functioning deficits during adolescence, specifically in peer relationships, as plausible independent risk factors for later psychiatric disorders. These results can be utilized in identifying possible at-risk groups and targets for prevention and in developing preventive strategies.

Abstract
BACKGROUND Social functioning deficits occur prior to the onset of psychosis and predict conversion to psychosis in clinical high-risk (CHR) populations. The Social Functioning Scale (SFS), a self-report measure of social functioning, is widely used in adults with psychosis but has not been tailored to CHR individuals. CHR syndromes overlap with the adolescent/young-adult developmental period, a time with unique social demands and contexts. The current study evaluates a modified version of the SFS in CHR individuals. METHODS Two independent samples of CHR participants (n = 84 and n = 45) and non-CHR participants (n = 312 and n = 42) completed the SFS and a psychosis-risk interview. Resulting factors were compared across diagnostic categories (CHR, Major Depressive Disorder, Generalized Anxiety Disorder) and community controls (CC) who were not excluded for any psychopathology except psychosis, depression, and anxiety. CHR participants completed scales of negative symptoms, global social and role functioning, cognition, and finger tapping as measures of convergent and divergent validity. RESULTS Exploratory factor analysis identified three SFS factors (RMSEA = 0.05) which demonstrated reliability in a confirmatory analysis in an independent sample: Recreation (α = 0.82), Nightlife (α = 0.85), and Interpersonal (α = 0.69). Factors and their composite score demonstrated increased social deficits in CHR compared to CC and depression groups and showed expected convergent (r's = 0.30-0.54) and divergent (r's = -0.004-0.26) validity with appropriate measures. CONCLUSIONS These findings suggest that there are reliable, valid, and developmentally relevant categories of social behavior within the SFS that differentiate between CHR and MDD or CC individuals. Recommendations for future work with CHR populations are included.

Abstract
Social functioning deficits (SFDs) during adolescence represent potential vulnerability indicators to schizophrenia spectrum disorders, but little is known about how both family environmental and genetic factors contribute to SFDs. The aim of this study was to examine the association of adoptees' adolescent social functioning with adoptive family functioning and adoptees' high (HR) or low (LR) genetic risk for schizophrenia spectrum disorders. The present subsample from the nationwide Finnish Adoptive Family Study of Schizophrenia included 88 HR and 83 LR adoptees. Adolescent social functioning was assessed using UCLA Social Attainment Survey. Assessment of adoptive family functioning was based on Global Family Ratings. Results indicated that dysfunctional family processes and high genetic risk for schizophrenia spectrum disorders contributed approximately equally to adoptees' adolescent social functioning. Our findings underscore the importance of functional family processes in adolescent social functioning, particularly in individuals at high genetic risk for severe psychiatric disorder.

Abstract
Social disconnection is associated with poor outcome and long-term disability in individuals with schizophrenia-spectrum conditions (SCZ) but social isolation is not typically a target for treatment. Singing together has long been shown to promote unique group cohesion and improve sense of well-being across the lifespan. Accordingly, we devised a novel choral intervention to examine the potential efficacy of this low-burden social intervention strategy designed to reduce loneliness in SCZ. Seventeen SCZ participated in a weekly, 1-hr choir group for 8 weeks. At pre- and post-intervention, we examined symptoms, loneliness, stress, and face recognition. Choral intervention led to significant reductions in scores for loneliness, the Brief Psychiatric Rating Scale (BPRS) and the Beck Depression Inventory-II (BDI-II). No significant changes were observed in scores for the Scale for the Assessment of Negative Symptoms (SANS), the Scale for the Assessment of Positive Symptoms (SAPS), face recognition, or the Perceived Stress Scale (PSS). Diminished loneliness was inversely correlated with the number of sessions attended. Participants judged the choir intervention to be acceptable and enjoyable. Reduced loneliness and symptom improvement after 8 weeks of intervention in SCZ suggest that choral intervention presents an enjoyable and low-burden opportunity to collaborate in a group setting for isolated individuals and thus may serve as a beneficial adjunct in a multi-arm intervention strategy for alleviating symptom distress and loneliness.

Abstract
Social functioning is diminished among people early in the course of psychotic illnesses, and is likely influenced by the negative symptoms that accompany these disorders, including changes in motivation and experience of pleasure. Though social impairments have a deleterious impact on functioning, socialization is a multifaceted behavior and little is known about how the various aspects may influence social functioning and social quality of life among people with first-episode psychosis. In the present study, we investigated the associations of specific aspects of social motivation and behavior with social functioning and social quality of life in a group of 54 young people (aged 15 to 35) with first-episode psychosis. Though different aspects of social motivation and behavior correlated positively with one another, social motivation for peer interactions was uniquely associated with social functioning and social quality of life - including when a broad measure of negative symptoms was considered within the same model. When these same associations were examined longitudinally, social motivation for peer interactions again emerged as a unique predictor of change in social functioning over 6 months. Our results suggest that the unique contribution of aspects of social motivation has implications for treatment, including the importance of developmentally-informed interventions to improve peer socialization in youth and young adults with psychosis.

Abstract
Social dysfunction is a risk indicator for schizophrenia spectrum disorders, with at-risk individuals demonstrating a range of social behavior impairments. Variability in social ability may be explained by individual differences in the psychological processes of social behavior. In particular, mental simulation, the process by which an individual generates an internal representation of the thoughts or feelings of another, may explain variation in social behavior. This study investigates the neural process of simulation in healthy individuals and individuals at risk for psychosis. Using a novel fMRI pain paradigm, individuals watch videos of another person’s hand or foot experiencing pain. After each video, individuals are asked to simulate the observed painful situation on their own hand or foot. Neural activity during simulation in the somatosensory cortex was associated with real-world self-reported social behavior, such that a stronger neural response in the somatosensory cortex was associated with greater rates of positive social experiences and affective empathy across all participants. These findings suggest that the neural mechanisms that underlie simulation are important for social behavior, and may explain individual variability in social functioning in healthy and at-risk populations.

The Mediation Role of Self-Esteem for Self-Stigma on Quality of Life for People With Schizophrenia: A Retrospectively Longitudinal Study. JOURNAL OF PACIFIC RIM PSYCHOLOGY 2021.

Abstract
Background: Among patients with schizophrenia, there is evidence of a negative association between self-stigma and subjective quality of life (SQoL), and self-esteem was an important mediator in the association. We attempted to use a longitudinal study to investigate the aforementioned mediation on a sample with schizophrenia. Methods: We used longitudinal data retrieved from medical records of a psychiatric centre between June 2014 and December 2015. In the data, we retrieved information of self-stigma using the Self-Stigma Scale — Short; SQoL, using the WHO questionnaire on the Quality of Life — Short Form; and self-esteem, using the Rosenberg Self-Esteem Scale. All the measures were evaluated five times. Linear mixed-effect models accompanied by Sobel tests were used to tackle the mediating effects. Results: Data from 74 patients (57 males) with schizophrenia were eligible for analysis; their mean ( SD) age was 39.53 (10.67); mean age of onset was 22.95 (8.38). Self-esteem was a mediator for patients in physical ( p = .039), psychological ( p = .003), and social SQoL ( p = .004), but not in environment SQoL ( p = .051). Conclusion: Based on our findings, mental health professionals could tailor different programs to patients with schizophrenia, such as self-stigma reduction and self-esteem improvement programs. However, treatment as a whole should be sensitive to both self-stigma and self-esteem. Also, we should consider individuals’ health and wellbeing from social perspectives of disability rather than the medical model of disability emphasising symptoms and medications.

Abstract
Impaired social functioning is a hallmark of schizophrenia and altered functional integration between distant brain regions are expected to account for signs and symptoms of the disorder. The functional neuroarchitecture of a network relevant for social functioning, the mentalizing network, is however poorly understood. In this study we examined dysfunctions of the mentalizing network in patients with schizophrenia compared to healthy controls via dynamic causal modelling and an interactive social decision-making game. Network characteristics were analyzed on a single subject basis whereas graph theoretic metrics such as in-degree, out-degree and edge-connectivity per network node were compared between the groups. The results point to a sparser network structure in patients with schizophrenia and highlight the dorsomedial prefrontal cortex as a disconnected network hub receiving significantly less input from other brain regions in the network. Further analyses suggest that integrating pathways from the right and the left temporo-parietal junction into the dorsomedial prefrontal cortex were less frequently found in patients with schizophrenia. Brain and behavior analyses further suggest that the connectivity-intactness within the entire network is associated with functional interpersonal behavior during the task. Thus, the neurobiological alterations within the mentalizing network in patients with schizophrenia point to a specific integration deficit between core brain regions underlying the generation of higher-order representations and thereby provide a potential treatment target.

Abstract
BACKGROUND Cannabis use is highly prevalent among people with a psychotic disorder. They often report sociality, coping with unpleasant affect and having positive experiences as important reasons for cannabis use, suggesting that cannabis improves their quality of life (QoL) and psychosocial functioning. However, based on previous studies we hypothesize that cannabis use is negatively associated with long-term subjective QoL and psychosocial functioning in people with a psychotic disorder. METHODS We included 2994 people with a psychotic disorder (36.4% female), mean age 44.4 (SD 11.9), mean illness duration 17.2 years (SD 11.1), who participated in two yearly routine outcome assessments between 2014 and 2018 (interval 9-15 months) from the naturalistic PHAMOUS cohort study. Linear regression analyses were used to examine whether first assessment cannabis use was associated with QoL (ManSA) and psychosocial functioning (HoNOS). Changes in outcomes between assessments were analyzed with AN(C)OVA, to examine differences between continuers (n = 255), discontinuers (n = 85), starters (n = 83) and non-users (n = 2571). RESULTS At first assessment, 11.4% was using cannabis. They had lower QoL (B = -2.93, p < 0.001) and worse psychosocial functioning (B = 1.03, p = 0.002) than non-users. After one year, changes in QoL and psychosocial functioning were not significantly different between continuers, starters, discontinuers and non-users. CONCLUSIONS Cannabis users were less satisfied with their family relations and financial situation and showed more aggressive and disruptive behavior and self-harm than non-users. These differences are likely the result of patients having used cannabis for many years. Starting or discontinuing cannabis did not lead to changes in QoL and psychosocial functioning within one year.

Abstract
Social exclusion and rejection have deleterious effects on psychological well-being. Research documents the negative effects of social exclusion and rejection on psychiatric problems like depression, social anxiety disorder, and non-suicidal self-injury. Additionally, prior research suggests that individuals with and at-risk for psychosis spectrum disorders may also be negatively affected by exclusion and rejection. Moreover, those on the psychosis spectrum may be at an even greater risk to experience social exclusion due to poor social functioning and the stigma surrounding the disorder. This systematic review aimed to investigate how individuals across the psychosis spectrum respond to social exclusion and rejection. We systematically searched PubMed and PsycINFO databases to identify studies that met the following eligibility criteria: 1) investigated social exclusion or rejection, 2) targeted a psychosis-related sample or symptoms, and 3) was an empirical study. 13 studies satisfied our eligibility criteria and were subsequently reviewed. Despite methodological variation and samples spanning the psychosis spectrum, the majority of the literature supports the conclusion that those with psychosis spectrum disorders report similar levels of exclusion-induced distress compared to healthy controls, but process and cope with exclusion differently, both behaviorally and neurobiologically.

Abstract
BACKGROUND Social anxiety disorder (SAD) commonly occurs among individuals at clinical high-risk (CHR) for psychosis. Extant research has yet to examine the prevalence and clinical/functional correlates of SAD in this population compared to a community control (CC) sample. This comparison may improve the generalizability that traditional nonpsychiatric control samples cannot provide. Additionally, it remains unknown how SAD contributes to symptom severity and social impairments in individuals at CHR for psychosis. METHODS Both CHR and CC groups were recruited from general community sources; CC participants were not excluded in this analysis on the basis of any psychopathology except psychosis. A total of 245 adolescents and young adults (CHR = 81; CC = 164) were administered the Social Phobia Scale, the Structured Interview for Psychosis-risk Syndromes, Structured Clinical Interview for DSM-5 Research Version, and the Social Functioning Scale. RESULTS The CHR group was at increased risk for having SAD relative to CC (42% CHR; 13% CC; RR = 3.28) and, to a lesser degree, a non-SAD anxiety disorder (41% CHR; 29% CC; RR = 1.42). Greater social anxiety was related to higher levels of negative (r = 0.29) but not positive (r = 0.05) symptoms within the CHR group. Furthermore, elevated social anxiety was found to be linked with poor social functioning in the CHR group (r = -0.31). CONCLUSIONS These findings demonstrate the specificity of SAD over and above other anxiety disorders in individuals at CHR for psychosis and the critical target of SAD to treat subclinical psychotic symptoms and social functioning.

Abstract
Love is a universal experience that most people desire. A serious, long-term, and stigmatized illness makes entering and maintaining close relationships difficult, however. Ten persons, who have been diagnosed with schizophrenia, and lived with their illness for between years and decades of their lifetimes, shared their stories. They reported how the illness has influenced their emotional experiences regarding love and their intimate relationship experiences. We present here a qualitative interpretative phenomenological analysis (IPA) of their narratives. This analysis has been done with an explicit intention to give voice to the patient’s perspective. The results highlight how illness adjustment and hospitalizations have an alienating effect on relationships through stigmatization and self-stigmatization; how illness creates psychological obstacles to love, such as diminished trust toward oneself and others; and how long-term patients experience practical difficulties in creating and sustaining relationships, such as poverty. Moreover, we show how patients experience changes in sexuality and the risks involved in it and discuss possible coping strategies from their perspectives.

Mesenchymal stem cells derived extracellular vesicles improve behavioral and biochemical deficits in a phencyclidine model of schizophrenia. Transl Psychiatry 2020; 10:305.

Abstract
Schizophrenia is a debilitating psychiatric disorder with a significant number of patients not adequately responding to treatment. Phencyclidine (PCP) is used as a validated model for schizophrenia, shown to reliably induce positive, negative and cognitive-like behaviors in rodents. It was previously shown in our lab that behavioral phenotypes of PCP-treated mice can be alleviated after intracranial transplantation of mesenchymal stem cells (MSC). Here, we assessed the feasibility of intranasal delivery of MSCs-derived-extracellular vesicles (EVs) to alleviate schizophrenia-like behaviors in a PCP model of schizophrenia. As MSCs-derived EVs were already shown to concentrate at the site of lesion in the brain, we determined that in PCP induced injury the EVs migrate to the prefrontal cortex (PFC) of treated mice, a most involved area of the brain in schizophrenia. We show that intranasal delivery of MSC-EVs improve social interaction and disruption in prepulse inhibition (PPI) seen in PCP-treated mice. In addition, immunohistochemical studies demonstrate that the EVs preserve the number of parvalbumin-positive GABAergic interneurons in the PFC of treated mice. Finally, MSCs-EVs reduced glutamate levels in the CSF of PCP-treated mice, which might explain the reduction of toxicity. In conclusion, we show that MSCs-EVs improve the core schizophrenia-like behavior and biochemical markers of schizophrenia and might be used as a novel treatment for this incurable disorder.

Abstract
Individuals who experience symptoms of mania in the form of a manic episode (ME) are at a greater risk of experiencing psychological distress. Given that a ME is a period during which one can become extremely socially dysfunctional, the potential influence of social support is especially important to explore. The primary objective of this study was to examine whether perceived social support predicts psychological distress in a sample of Canadian adults who have self-reported ME symptoms within the last 12-months. Using a cross-sectional, national datafile, 220 Canadians between 20 and 64 years who met the criteria for a ME within the last 12-months were investigated using the Social Provisions Scale (SPS), and the Kessler Psychological Distress Scale (K10). Results indicated that the ME sample experienced significantly higher distress and significantly lower perceived social support than the adult Canadian population. Further, social support in the form of reassurance of worth was associated with lower levels of psychological distress, but only for the male ME sample, and the overall (male and female combined) ME sample. Despite some limitations, this study adds to the research on mania as its own experience outside of comorbidities and indicates the important and specific role social support plays in terms of psychological well-being.

Abstract
Recent studies have demonstrated substantial phenotypic overlap, notably social impairment, between autism spectrum disorder (ASD) and schizophrenia. However, the neural mechanisms underlying the pathogenesis of social impairments across these distinct neuropsychiatric disorders has not yet been fully examined. Most neuroimaging studies to date have focused on adults with these disorders, with little known about the neural underpinnings of social impairments in younger populations. Here, we present a narrative review of the literature available through April 2020 on imaging studies of adolescents with either ASD or early-onset psychosis (EOP), to better understand the shared and unique neural mechanisms of social difficulties across diagnosis from a developmental framework. We specifically focus on functional connectivity studies of the default mode network (DMN), as the most extensively studied brain network relevant to social cognition across both groups. Our review included 29 studies of DMN connectivity in adolescents with ASD (Mean age range = 11.2-21.6 years), and 14 studies in adolescents with EOP (Mean age range = 14.2-24.3 years). Of these, 15 of 29 studies in ASD adolescents found predominant underconnectivity when examining DMN connectivity. In contrast, findings were mixed in adolescents with EOP, with five of 14 studies reporting DMN underconnectivity, and an additional six of 14 studies reporting both under- and over-connectivity of the DMN. Specifically, intra-DMN networks were more frequently underconnected in ASD, but overconnected in EOP. On the other hand, inter-DMN connectivity patterns were mixed (both under- and over-connected) for each group, especially DMN connectivity with frontal, sensorimotor, and temporoparietal regions in ASD, and with frontal, temporal, subcortical, and cerebellar regions in EOP. Finally, disrupted DMN connectivity appeared to be associated with social impairments in both groups, less so with other features distinct to each condition, such as repetitive behaviors/restricted interests in ASD and hallucinations/delusions in EOP. Further studies on demographically well-matched groups of adolescents with each of these conditions are needed to systematically explore additional contributing factors in DMN connectivity patterns such as clinical heterogeneity, pubertal development, and medication effects that would better inform treatment targets and facilitate prediction of outcomes in the context of these developmental neuropsychiatric conditions.

Family burden predicts functional outcome in the early course of schizophrenia beyond psychiatric symptoms and baseline functioning. Schizophr Res 2018; 202:328-332.

Abstract
The goal of this study was to determine if family burden experienced by the families of individuals with a recent-onset of schizophrenia is associated with whether the individual is able to work or attend school during the first year of treatment. Forty-one participants with a recent first episode of schizophrenia and their families enrolled in two NIMH-funded protocols through the UCLA Aftercare Research Program completed a measure of family burden at baseline. Amount of work during this time was also recorded. Baseline family burden was associated with work status (no work, part-time work, or full-time work) at both the six-month, r = -0.321, p = .04, and one-year time point, r = - 0.47, p = .002. Family burden was also associated with hours participated in work/school hours at the six-month time point, r = -0.390, p = .012, and at the one-year time point, r = -0.492, p = .01. Further exploration into the family burden measure shows that family perceived limited opportunities resulting from the individual's psychiatric disorder was associated with worse functional outcome at all three time points beyond psychiatric symptoms and baseline functioning. Missed opportunities due to a family member's illness may reduce the level of support provided to the individual and thus impact their psychosocial functioning. Our findings suggest that this dimension of family burden is highlighting the importance of and need for more balanced family support to boost functional outcome.

Abstract
Mental health interventions do not yet offer complete, client-defined functional recovery, and novel directions in treatment research are needed to improve the efficacy of available interventions. One promising direction is the integration of social work and cognitive neuroscience methods, which provides new opportunities for clinical intervention research that will guide development of more effective mental health treatments that holistically attend to the biological, social, and environmental contributors to disability and recovery. This article reviews emerging trends in cognitive neuroscience and provides examples of how these advances can be used by social workers and allied professions to improve mental health treatment. We discuss neuroplasticity, which is the dynamic and malleable nature of the brain. We also review the use of risk and resiliency biomarkers and novel treatment targets based on neuroimaging findings to prevent disability, personalize treatment, and make interventions more targeted and effective. The potential of treatment research to contribute to neuroscience discoveries regarding brain change is considered from the experimental-medicine approach adopted by the National Institute of Mental Health. Finally, we provide resources and recommendations to facilitate the integration of cognitive neuroscience into mental health research in social work.

Abstract
Impairments in social cognition may reflect dysfunction of disorder specific or disorder general mechanisms. Although cross-disorder comparison may prove insightful, few studies have compared social cognition in different neuropsychiatric disorders. Parallel investigation of schizophrenia and Tourette syndrome (TS) is encouraged by similarities including the presence of problematic social behavior, echophenomena, emotional dysregulation and dopamine dysfunction. Focusing on tests of social cognition administered in both disorders, this review aims to summarize behavioral, neurophysiological and neuroimaging findings, before exploring how these may contribute to clinical symptoms. Studies investigating social cognition (imitation, emotion recognition, and understanding of beliefs or intentions) in patients with schizophrenia or TS were identified through Web of Science and PubMed searches. Although findings indicate that social cognitive deficits are more apparent in schizophrenia, adults with TS can exhibit similar task performance to patients with paranoia. In both disorders, behavioral and neuroimaging findings raise the possibility of increased internal simulation of others' actions and emotions, in combination with a relative under-application of mentalizing. More specifically, dysfunction in neurobiological substrates such as temporo-parietal junction and inferior frontal gyrus may underlie problems with self-other distinctions in both schizophrenia and TS. Difficulties in distinguishing between actions and mental states linked to the self and other may contribute to a range of psychiatric symptoms, including emotional dysregulation, paranoia, social anhedonia and socially disruptive urges. Comparing different patient populations could therefore reveal common neuro-cognitive risk factors for the development of problematic social behaviors, in addition to markers of resilience, coping strategies and potential neuro-compensation mechanisms.

Abstract
Introduction: Homeless individuals are often mischaracterized as members of a homogeneous population that suffers from a wide mental health and addiction issues, with little consideration of potentially important differences within or between samples. The aim of the present study was to investigate the comorbidy of alcohol and/or substance dependence (ASD) and major psychiatric diagnoses (bipolar disorder, unipolar depression, and psychotic disorder) in a large Canadian sample of homeless individuals, and to examine potential sources of variability including location and ethnicity. Materials and Methods: A sample of 1,585 homeless individuals were assessed for alcohol and/or substance dependence and bipolar disorder, unipolar depression and psychotic disorder with the Mini-International Neuropsychiatric Interview (version 6.0). Regional and ethnic differences in major psychiatric diagnoses between homeless with and without ASD were examined using univariate (i.e., chi-square) and multivariate (i.e., logistic regression) statistics. Results: Members of the sample with ASD were found to be younger, Aboriginal, less well-educated, and born in the Americas. They were more significantly more prevalent in Western Canada and less prevalent in Central and Eastern Canada. The odds of having ASD were higher among people affected by bipolar disorder and (to a less extent) unipolar depression. Limitations: Data collected were self-reported and no urinalyses were performed. We considered diagnosis of ASD according to the previous 12 months only. Conclusions: Homeless people with major mental illness are at high risk for concurrent ASD, however the prevalence of ASD varies significantly between cities, and based on ethnicity and specific psychiatric diagnosis (with greater prevalence in individuals affected by bipolar disorder and, to a less extent, unipolar depression). Clinicians, administrators and policy makers should develop and deliver services based on careful assessment of the local population.

Abstract
Recent empirical findings from clinical and genetic studies suggest that mentalization, a key area of social cognition, is a distinct construct, although it is closely related to the neurocognitive deficits and symptoms of schizophrenia. Mentalization contributes a great deal to impaired social functioning. Current measures often display methodological problems, and many aspects should be taken into account when assessing mentalization. Moreover, advances in cognitive and affective neurosciences have led to the development of more advanced behavioral methods to assess the relationship between cognitive functions, symptoms, and social cognition based on their underlying neural mechanisms. The development of assessment tools that better examine the neural circuitry of such relationships may lead to the development of new psychosocial and pharmacological treatments.

Abstract
Clinical health professionals may have difficulties to select appropriate schizophrenia-specific Quality of life (QoL) instruments because of the limited information regarding their psychometric properties. Two widely used schizophrenia-specific QoL instruments (Schizophrenia Quality of Life Scale Revision 4 [SQLS-R4] and Lancashire Quality of Life Profile [LQOLP]) were compared in institutionalized people with schizophrenia, and useful recommendations for clinical health professionals were provided. Participants (n = 100) filled out the two instruments twice. Test-retest reliability, internal consistency, and confirmatory factor analyses (CFAs) were conducted. Both SQLS-R4 domains (r = 0.573-0.731) and LQOLP domains (r = 0.303-0.778) had good test-retest reliability. However, the objective QoL domains in the LQOLP showed lower internal consistency (α = 0.219-0.617) than its subjective QoL domains (α = 0.532-0.947) and the SQLS-R4 domains (α = 0.768-0.939). The CFAs with two correlated underlying instruments constructs and two correlated underlying QoL traits (viz., Physical and Psychosocial QoL) performed the best data-model fit (CFI = 0.990, RMSEA = 0.039, SRMR = 0.039), which supported the validity of both instruments. Although both SQLS-R4 and LQOLP were valid and reliable, using SQLS-R4 on institutionalized people seemed to be more psychometrically solid than using the LQOLP.

Abstract
OBJECTIVE Conformity is defined as the act of adjusting one's behavior to match the social responses of others. Patients with schizophrenia often adjust their maladaptive behaviors by conforming in group treatment settings. This study aimed to examine whether the opinions of group members influence conformity of patients with schizophrenia who attend day-hospital programs. METHODS Nineteen patients with schizophrenia from four different day-hospital programs and 23 healthy controls from four different social clubs completed the homographic meaning choice task under conditions of prior exposure to the pseudo-opinions of their group members, strangers, and unknown information sources. Group influences on conformity were observed when the level of group cohesiveness was high and the level of intimacy was low across participant groups. RESULTS Controls did not exhibit a significant effect of group influence on conformity, whereas patients were significantly influenced by their group members when making conformity-based decisions despite significantly lower intimacy and cohesiveness levels. CONCLUSION These findings suggest that unlike controls, patients with schizophrenia tend to respond with conformity when influenced by the opinions of their affiliated group. In patients with schizophrenia group conformity may be used to select a more accurate decision and to enhance feelings of affiliation among them.

Abstract
BACKGROUND AND OBJECTIVES The negative symptoms of schizophrenia are related to lower social functioning even in non-clinical samples, but little is known about the distinct social consequences of motivational and expressive negative symptoms. In this study we focused on expressive negative symptoms and examined how these symptoms and varying degrees of pro-social facial expressiveness (smiling and mimicry of smiling) relate to the social evaluations by face-to-face interaction partners and to social support. METHODS We examined 30 dyadic interactions within a sample of non-clinical participants (N = 60) who were rated on motivational and expressive negative symptoms with the Clinical Assessment Interview for Negative Symptoms (CAINS). We collected data on both interaction partners' smiling-muscle (zygomaticus major) activation simultaneously with electromyography and assessed the general amount of smiling and the synchrony of smiling muscle activations between interaction partners (mimicry of smiling). Interaction partners rated their willingness for future interactions with each other after the interactions. RESULTS Interaction partners of participants scoring higher on expressive negative symptoms expressed less willingness for future interactions with these participants (r = -0.37; p = 0.01). Smiling behavior was negatively related to expressive negative symptoms but also explained by motivational negative symptoms. Mimicry of smiling and both negative symptom domains were also associated with participants' satisfaction with their social support network. LIMITATIONS Non-clinical sample with (relatively) low levels of symptoms. CONCLUSIONS Expressive negative symptoms have tangible negative interpersonal consequences and directly relate to diminished pro-social behavior and social support, even in non-clinical samples.

Abstract
Mental illness and substance use are overrepresented within urban homeless populations. This paper compared substance use patterns between homeless individuals diagnosed with schizophrenia spectrum (SS) and bipolar disorders (BD) using the Mini-International Neuropsychiatric Interview. From a sample of 497 subjects drawn from Vancouver, Canada who participated in the At Home/Chez Soi study, 146 and 94 homeless individuals were identified as BD and SS, respectively. In the previous 12 months, a greater proportion of BD homeless reported greater use of cocaine (χ = 20.0, p = 0.000), amphetamines (χ = 13,8, p = 0.000), opiates (χ = 24.6, p = 0.000), hallucinogens (χ = 11.7, p = 0.000), cannabinoids (χ = 5.05, p = 0.034), and tranquilizers (χ = 7.95, p = 0.004) compared to SS. Cocaine and opiates were significantly associated with BD homeless (χ = 39.06, df = 2, p < 0.000). The present study illustrates the relationship between substance use and BD in a vulnerable urban population of homeless, affected by adverse psychosocial factors and severe psychiatric conditions.

Abstract
Background: Negative stressors can aggravate the impact of schizophrenia. However, some people find ways of combating such stressors. There is a dearth of research examining factors which enable individuals with schizophrenia to show psychological resilience.Aims: The goal of this study was to investigate resilience to negative stressors in people with disorders on the schizophrenia spectrum using a qualitative methodology.Methods: Data were collected from 23 participants who had experienced schizophrenia and suicidal thoughts and behaviours. Semi-structured interviews followed a topic guide. Participants were asked (i) what resilience meant to them, (ii) which stressors they had experienced over 12 months and (iii) how they had counteracted those stressors. Thematic analysis was conducted to identify re-occurring themes across interviews.Results: A continuum of psychological mechanisms described participants' views about the meaning of resilience which ranged from passive acceptance to resistance (e.g. withstanding pressure), and then to active strategies to counter stressors (e.g. confronting). These themes were also evident in narratives expressing personal resilience strategies but, additionally, included emotional coping techniques. External factors were highlighted that supported resilience including social support, reciprocity and religious coping.Conclusions: People with schizophrenia develop ways of being resilient to negative events which should inform therapeutic interventions.

Abstract
Studies suggest that individuals with schizophrenia have smaller social networks and less satisfying relationships. However, much is still unknown about the typical quantity and quality of social relationships in young adults during the ultra high-risk (UHR) period. Investigating these relationships holds significant importance for improving understanding of etiological processes, mapping the social environment, and highlighting treatment targets in a critical period. A total of 85 participants (44 UHR and 41 healthy controls) completed measures examining the participants' social relationships, social support, and loneliness. Mean differences between the UHR and healthy control participants and associations between social relationships and symptoms and functioning were examined. Results indicated significant differences between groups on several indices. Specifically, the UHR youth reported fewer close friends, less diverse social networks, less perceived social support, poorer relationship quality with family and friends, and more loneliness. Notably, within the UHR group, being lonely and having fewer and worse quality relationships was associated with greater symptom severity and lower overall functioning. This study suggests that youth at high-risk of developing psychosis have fewer and poorer quality social relationships. Interventions that focus on increasing the quantity and quality of young adults' social networks may be beneficial for this population.

Abstract
While research using Experience Sampling Methodology (ESM) suggests that, in general, contact with relatives or friends may be protective for psychotic experiences, contact with high-Expressed Emotion (high-EE) relatives can have adverse consequences for patients. This study investigated whether contact with high-EE relatives, and relatives' behaviourally controlling interactions (BCI) are related to patients' symptoms and to both patients' and relatives' affect when measured using structured diary assessments in the course of everyday life. Twenty-one patients experiencing psychosis and their closest relatives provided synchronized self-reports of symptoms (patients only), affect, dyadic contact and BCI over a 6-days period. Relatives' EE was obtained from Camberwell Family Interviews. Multi-level modeling showed that patients' reports of relatives taking control of them and helping them were associated with increased patient negative affect and symptoms. Relatives' self-reports of nagging, taking control and keeping an eye on the patient were related to fluctuations in relatives' affect. No evidence was found for the moderating effect of EE status on the association between dyadic contact and affect or, in the case of patients, symptoms. When measured using an ecologically valid methodology, momentary behaviourally controlling interactions within dyads experiencing psychosis can impact on patients' affect and symptoms.

Abstract
PURPOSE The aim of this study was to compare the effects of risperidone long-acting injection (RLAI) and paliperidone palmitate (PP) on non-acute-phase social functioning in patients with schizophrenia. PATIENTS AND METHODS In this 6-month pilot, open-label, randomized controlled study, 30 patients with schizophrenia who had been treated with RLAI were randomly allocated to the RLAI continuation group or switched to the PP group. Patients were evaluated at baseline and 6 months with the Social Functioning Scale (SFS) as the primary outcome variable and University of California San Diego Performance-Based Skills Assessment Brief (UPSA-B), Social Emotional Cognition Task (SECT), Positive and Negative Syndrome Scale (PANSS), and Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) scores as secondary outcomes. RESULTS At baseline, the two groups did not significantly differ in demographic or clinical features. The two groups did not differ in total score changes for the UPSA-B, the SECT, the PANSS, and the DIEPSS. However, the total scores and the two subscales of the SFS, i.e. independence-competence and independence-performance, were more improved in the PP group compared to the RLAI group (total scores, p = 0.038; competence, p = 0.001, and performance, p = 0.007, respectively). CONCLUSION These results suggest that PP may improve the total social functioning, independent life competence, and performance as compared to the RLAI group. However, these results are preliminary and need independent replication in larger samples before any definitive statement can be made.

Abstract
The aim of the present study was to assess the relationship between illness-related characteristics, such as symptom severity and psychosocial functioning, and specific aspects of family functioning both in patients experiencing their first episode of psychosis (FEP) and chronically ill patients. A total of 50 FEP and 50 chronic patients diagnosed with schizophrenia or bipolar disorder (most recent episode manic severe with psychotic features) and their family caregivers participated in the study. Family functioning was evaluated in terms of cohesion and flexibility (FACES IV Package), expressed emotion (FQ), family burden (FBS) and caregivers' psychological distress (GHQ-28). Patients' symptom severity (BPRS) and psychosocial functioning (GAS) were assessed by their treating psychiatrist within 2 weeks from the caregivers' assessment. Increased symptom severity was associated with greater dysfunction in terms of family cohesion and flexibility (β coefficient -0.13; 95 % CI -0.23, -0.03), increased caregivers' EE levels on the form of emotional overinvolvement (β coefficient 1.03; 95 % CI 0.02, 2.03), and psychological distress (β coefficient 3.37; 95 % CI 1.29, 5.45). Family burden was found to be significantly related to both symptom severity (β coefficient 3.01; 95 % CI 1.50, 4.51) and patient's functioning (β coefficient -2.04; 95 % CI -3.55, -0.53). No significant interaction effect of chronicity was observed in the afore-mentioned associations. These findings indicate that severe psychopathology and patient's low psychosocial functioning are associated with poor family functioning. It appears that the effect for family function is significant from the early stages of the illness. Thus, early psychoeducational interventions should focus on patients with severe symptomatology and impaired functioning and their families.

Abstract
Language and thought dysfunction are central to the schizophrenia syndrome. They are evident in the major symptoms of psychosis itself, particularly as disorganized language output (positive thought disorder) and auditory verbal hallucinations (AVHs), and they also manifest as abnormalities in both high-level semantic and contextual processing and low-level perception. However, the literatures characterizing these abnormalities have largely been separate and have sometimes provided mutually exclusive accounts of aberrant language in schizophrenia. In this review, we propose that recent generative probabilistic frameworks of language processing can provide crucial insights that link these four lines of research. We first outline neural and cognitive evidence that real-time language comprehension and production normally involve internal generative circuits that propagate probabilistic predictions to perceptual cortices - predictions that are incrementally updated based on prediction error signals as new inputs are encountered. We then explain how disruptions to these circuits may compromise communicative abilities in schizophrenia by reducing the efficiency and robustness of both high-level language processing and low-level speech perception. We also argue that such disruptions may contribute to the phenomenology of thought-disordered speech and false perceptual inferences in the language system (i.e., AVHs). This perspective suggests a number of productive avenues for future research that may elucidate not only the mechanisms of language abnormalities in schizophrenia, but also promising directions for cognitive rehabilitation.

Abstract
Impaired social functioning is a characteristic of schizophrenia that affects patients' quality of life. The aim of the study was to assess prefrontal hemodynamic responses during a cognitive task and establish its influence on psychiatric symptoms, cognitive function, global functioning, and self-reported social functioning in patients with schizophrenia. Thirty-three patients with schizophrenia and 30 age-and sex-matched healthy controls participated in the study. We measured hemodynamic responses in the prefrontal and superior temporal cortical surface areas with 52-channel near-infrared spectroscopy (NIRS) during a verbal fluency task (VFT). Self-reported social functioning was assessed using the Social Functioning Scale (SFS). Regional hemodynamic responses were significantly smaller in the prefrontal and temporal regions in subjects with schizophrenia than in the controls, and prefrontal hemodynamic responses during the VFT showed a strong correlation with SFS total scores. These results suggest an association between self-reported social functioning and prefrontal activation in subjects with schizophrenia. The present study provides evidence that NIRS imaging could be helpful in understanding the neural basis of social functioning.

Abstract
Social deficits are common in people with schizophrenia and the treatment of deficits in social competence has been a long-time treatment strategy. However, negative symptoms and social cognitive deficits also contribute to social dysfunction. In this study, we examined the correlations between everyday social outcomes, a performance based measure of social competence, and performance on 8 different social cognition tests in 179 patients with schizophrenia. Social cognition, social competence, and motivation-related negative symptoms accounted for 32% of the variance in real-world social outcomes. In addition, two different social cognition tests, along with expression-related negative symptoms accounted for 32% of the variance in performance-based assessments of social competence. These data suggest that negative symptoms exert an important influence on social outcomes and social competence, but not social cognition, and that social cognition and social competence exert separable influences on real-world social outcomes. Improving social outcomes seems to require a multi-faceted approach which considers social cognition, social competence, and negative symptoms.

Abstract
INTRODUCTION The overall goal of this study was to produce a user-friendly and high quality Internet-based patient education program for adolescents with psychosis. To achieve this, we ascertained the adolescents' and health care professionals' needs and expectations of patient education using Internet and the improvement proposals for an existing MentalNet program originally developed for adults with schizophrenia. METHODS The research process was conducted in two phases. First, adolescents' and healthcare professionals' needs for patient education and Internet were ascertained by interviewing adolescents and in two educational sessions with staff members (Phase I). Second, the preliminary evaluation of the Internet-based patient education program MentalNet was gathered from adolescents by an iterative process (see cyclic, recurring, repeating method), in one educational session with staff members and a questionnaire via email from other health care professionals (Phase II). RESULTS The needs and expectations of adolescents and health care professionals were related to the content, usability, design and realization of Internet-based patient education. Based on the information obtained the MentalNet program was modified to satisfy adolescents' needs. DISCUSSION The usefulness and effectiveness of the program will require scrutiny in future studies.
