Abstract
AIM Schizophrenia is a leading cause of disability worldwide; early detection and intervention are critical. Early in their illness, individuals at clinical high-risk (CHR) for psychosis have subthreshold psychotic symptoms that are often derogatory and self-directed. We hypothesized that CHR participants with negative self-reference (NSR) as a component of subthreshold psychosis would also have higher levels of social anxiety and depression, lower self-esteem and lower social/role/global functioning as compared with CHR participants without NSR. METHODS One hundred and sixty-eight participants from the National Institute of Mental Health (NIMH) funded Regroup Cognitive Behavioural Social Skills Training (CBSST) study were included. Clinical vignettes that included the Scale of Psychosis-Risk Symptoms were coded categorically to indicate whether NSR was present. t-tests were used to determine the association between NSR, symptom, and functional measures. RESULTS Participants with NSR demonstrated significantly more social interaction anxiety (p < .001), negative beliefs about the self (p ≤ .001), defeatist beliefs (p < .05), depressive symptoms (p < .05) and positive symptoms (p < .005). There were no significant differences in social self-efficacy, positive or negative beliefs about others, positive beliefs about the self or psychosocial functioning between the two groups. CONCLUSIONS Clinically significant differences were found between CHR participants with and without NSR, suggesting that this may be a useful factor to identify and address. Follow-up studies are needed to determine whether NSR responds to CBSST and whether or not its resolution would be associated with improvement in other symptom domains.

Abstract
Anomalous perceptual experiences in adolescents are common and may predict future psychotic disorders and other psychopathologies. However, the underlying structure and their specific relationships with bullying victimizations, a typical stressor for adolescents, remain unclear. Therefore, the current study aimed to clarify the structure of perceptual anomalies as assessed by the Cardiff Anomalous Perceptions Scale (CAPS) using exploratory graph analysis (EGA), a new factor retention method based on network psychometrics. The second aim was to explore whether specific dimensions of perceptual anomalies are particularly associated with certain forms of bullying victimization. Data from a validated sample of 1199 Chinese adolescents (56.0 % females, age range: 14-20) on perceptual anomalies and bullying victimizations were analyzed using network approaches, including EGA and mixed graphical modeling (mgm). Results showed that each anomalous perception was experienced by 13.8-50.3 % of the participants. EGA identified four dimensions: aberrant bodily perceptions, altered daily experiences, chemosensation (i.e., abnormal gustatory and olfactory experiences), and clinical psychosis (i.e., visual and auditory hallucinatory experiences). Among them, the altered daily experiences dimension possessed the highest centrality. Physical bullying and cyberbullying were directly and positively linked to two of the aberrant bodily experiences. Bootstrap analyses suggest that the results are reliable. The current findings support the existence of multiple contributive factors to perceptual anomalies and underscore the importance of bullying prevention in reducing mental health risks for adolescents, particularly the risk of psychosis.

Abstract
AIM The present study aimed at investigating the relationships between autistic features and cognitive deficits, functionality and quality of life in first episode psychosis (FEP) patients. METHODS Sixty FEP patients [mean age (SD) = 32.53 (10.74), n = 23 female, n = 37 male] were enrolled in this cross-sectional study. Data was collected using a sociodemographic and clinical data form, the Positive and Negative Syndrome Scale (PANSS), the PANSS Autism Severity Score (PAUSS), the Personal and Social Performance Scale (PSP), the Frontal Assessment Battery (FAB), and the World Health Organization Quality of Life Scale Short Form in Turkish Version (WHOQOL-BREF TR). RESULTS Autistic symptom severity was found to be higher in males than females, and higher in patients with a family history of psychotic disorder. An inverse relationship was found between the duration of education and the severity of autistic symptoms. While there was an inverse relationship between autistic symptom severity and executive functions and functionality, no significant correlation was found with quality of life. Negative symptom severity was a predictor of executive functions and functionality. No significant difference was observed between autistic and psychotic domains which were related to executive functions. CONCLUSIONS Our study is the first to examine the relationship between autistic/psychotic symptoms and executive functions and functionality in patients with FEP. The results show that autistic symptoms are associated with worse social and personal functioning and worse executive functions in patients with FEP. Longitudinal follow-up studies with larger samples are required to determine the direction of the relations.

Abstract
Background Schizophrenia affects about 1% of the global population. In addition to the complex etiology, linking this illness to genetic, environmental, and neurobiological factors, the dynamic experiences associated with this disease, such as experiences of delusions, hallucinations, disorganized thinking, and abnormal behaviors, limit neurological consensuses regarding mechanisms underlying this disease. Methods In this study, we recruited 72 patients with schizophrenia and 74 healthy individuals matched by age and sex to investigate the structural brain changes that may serve as prognostic biomarkers, indicating evidence of neural dysfunction underlying schizophrenia and subsequent cognitive and behavioral deficits. We used voxel-based morphometry (VBM) to determine these changes in the three tissue structures: the gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF). For both image processing and statistical analysis, we used statistical parametric mapping (SPM). Results Our results show that patients with schizophrenia exhibited a significant volume reduction in both GM and WM. In particular, GM volume reductions were more evident in the frontal, temporal, limbic, and parietal lobe, similarly the WM volume reductions were predominantly in the frontal, temporal, and limbic lobe. In addition, patients with schizophrenia demonstrated a significant increase in the CSF volume in the left third and lateral ventricle regions. Conclusion This VBM study supports existing research showing that schizophrenia is associated with alterations in brain structure, including gray and white matter, and cerebrospinal fluid volume. These findings provide insights into the neurobiology of schizophrenia and may inform the development of more effective diagnostic and therapeutic approaches.

Abstract
People meeting criteria for a clinical high-risk (CHR) for psychosis syndrome frequently represent a heterogeneous, help-seeking, and dynamic population. Among the numerous symptoms and risk factors for psychosis, exposure to trauma stands out as both highly prevalent and poorly understood. Indeed, while up to 80% of individuals meeting criteria for a CHR syndrome report trauma histories, there is currently limited research dedicated to this specific area. This is particularly problematic as trauma is tied to risk for conversion, leads to a range of clinical issues, and contributes to disability and poor quality of life. Fortunately, recent research in the general population has led to a significant evolution in the way trauma is assessed and understood, and further, some studies have indicated that targeted trauma interventions in formal psychotic disorders are highly effective. However, direct adoption is challenging as the CHR syndrome holds a number of unique concerns (e.g., clinical heterogeneity, developmental trauma), and characteristically, involves a developing pediatric or young adult population that also comes with specific considerations (e.g., living with caregivers, transitionary period in roles). In this "perspective" we frame the issues around understanding trauma in CHR individuals, discuss viable treatments and unique considerations, and provide suggestions for future steps in developing and incorporating trauma-focused interventions in this population.

Abstract
Aim Difficulties in social functioning have been observed in youth at clinical high-risk (CHR) of psychosis even in those who do not go on to develop a psychotic illness. Few treatment studies have attempted to improve social functioning in this population. The aim of this study was to conduct a randomized trial comparing the effects of Cognitive-Behavioral Social Skills Training (CBSST) with a supportive therapy (ST). Methods Both CBSST and ST were weekly group therapies, delivered over 18 weeks. This was a 2-arm trial with single-blinded ratings and intention-to-treat analyses. Assessments occurred at baseline, end-of-treatment, and 12 months after the baseline assessment. The primary outcome was social and role functioning and defeatist performance attitudes were the secondary outcome. Attenuated positive and negative symptoms, anxiety, depression, self-efficacy, and beliefs about self and others were examined as exploratory outcomes. Results There were no significant differences between the 2 groups at baseline or either of the 2 follow-ups. However, at follow-ups, in each group there were significant improvements in clinical symptoms. These could not be attributed to group treatment since there was no control or wait-list group. Conclusions Since poor social functioning is one of the most observed difficulties in CHR individuals, and a decline in social functioning may be a significant predictor of later transition to psychosis, future work will be needed to find effective treatments for this decline in functioning for CHR youth.

Abstract
Interventions for functional impairments in adolescents and young adults at clinical high risk (CHR) for psychosis are needed. Cognitive-Behavioral Social Skills Training (CBSST) has been found to improve functioning in patients with schizophrenia. The CBSST manual was adapted for CHR and implemented across 3 sites. The key changes that were made were to present a focus of normalization and destigmatization of attenuated psychotic symptoms and since CBSST has a major focus on role plays, problem solving and challenging thoughts, examples of these were changed to be more appropriate for this young CHR population. We describe the manual modifications and present fidelity data to examine the success of training and supervision methods in a multi-site randomized controlled trial of CBSST in CHR youth. Fidelity was high and comparable across sites. Case vignettes are presented to demonstrate how CBSST techniques were adapted for UHR individuals to target functional impairments.

Abstract
BACKGROUND The N400 event-related brain potential (ERP) semantic priming effect is thought to reflect activation by meaningful stimuli of related concepts in semantic memory and has been found to be deficient in schizophrenia. We tested the hypothesis that, among individuals at clinical high risk (CHR) for psychosis, N400 semantic priming deficits predict worse symptomatic and functional outcomes after one year. METHODS We measured N400 semantic priming at baseline in CHR patients (n = 47) and healthy control participants (n = 25) who viewed prime words each followed by a related or unrelated target word, at stimulus-onset asynchronies (SOAs) of 300 or 750 ms. We measured patients' psychosis-like symptoms with the Scale of Prodromal Symptoms (SOPS) Positive subscale, and academic/occupational and social functioning with the Global Functioning (GF):Role and Social scales, respectively, at baseline and one-year follow-up (n = 29). RESULTS CHR patients exhibited less N400 semantic priming than controls across SOAs; planned contrasts indicated this difference was significant at the 750-ms but not the 300-ms SOA. In patients, reduced N400 semantic priming at the 750-ms SOA was associated with lower GF:Social scores at follow-up, and greater GF:Social decrements from baseline to follow-up. Patients' N400 semantic priming was not associated with SOPS Positive or GF:Role scores at follow-up, or change in these from baseline to follow-up. CONCLUSIONS In CHR patients, reduced N400 semantic priming at baseline predicted worse social functioning after one year, and greater decline in social functioning over this period. Thus, the N400 may be a useful prognostic biomarker of real-world functional outcome in CHR patients.

Abstract
BACKGROUND Investigations into possible mechanisms that may contribute to the development, maintenance, and exacerbation of negative symptoms are needed. Defeatist beliefs, self-efficacy, and early maladaptive schemas have been shown to contribute to negative symptoms in schizophrenia. Likewise, negative symptoms occur in those at clinical high-risk (CHR) for psychosis. AIMS The aim of this study was to determine if negative symptoms were associated with defeatist beliefs, self-efficacy, and early maladaptive schemas in CHR participants of a group therapy intervention study. METHOD All CHR participants (n = 203; 99 males, 104 females) were recruited as part of a three-site randomized control trial: Recovery through Group Study (ReGroup). Negative symptoms, defeatist beliefs, self-efficacy and early maladaptive schemas were assessed by trained clinical raters. Mediation analyses were conducted to examine the relationship between defeatist beliefs, self-efficacy, functioning, and negative symptoms. RESULTS The majority of CHR youth (72.9%) had at least one negative symptom of moderate to above moderate severity at baseline. In multiple mediation analyses, both asocial beliefs and social self-efficacy mediated the effects of social functioning on negative symptoms. Finally, defeatist performance attitudes significantly mediated the effects of role functioning on negative symptoms. CONCLUSIONS These results highlight the importance of considering beliefs and attitudes in relation to functioning and severity of negative symptoms. Psychosocial interventions may wish to target beliefs and attitudes in effort to reduce negative symptoms and improve functioning in CHR youth.
