Neural correlates of aberrant emotional salience predict psychotic symptoms and global functioning in high-risk and first-episode psychosis

Neurobiological and behavioral findings suggest that psychosis is associated with corticolimbic hyperactivity during the processing of emotional salience. This has not been widely studied in the early stages of psychosis, and the impact of these abnormalities on psychotic symptoms and global functioning is unknown. We sought to address this issue in 18 patients with first-episode psychosis (FEP), 18 individuals at ultra high risk of psychosis (UHR) and 22 healthy controls (HCs). Corticolimbic response and subjective ratings to emotional and neutral scenes were measured using functional magnetic resonance imaging. The clinical and functional impact of corticolimbic abnormalities was assessed with regression analyses. The FEP and UHR groups reported increased subjective emotional arousal to neutral scenes compared with HCs. Across groups, emotional vs neutral scenes elicited activation in the dorsomedial prefrontal cortex, inferior frontal gyrus/anterior insula and amygdala. Although FEP and UHR participants showed reduced activation in these regions when viewing emotional scenes compared with controls, this was driven by increased activation to neutral scenes. Corticolimbic hyperactivity to neutral scenes predicted higher levels of positive symptoms and poorer levels of functioning. These results indicate that disruption of emotional brain systems may represent an important biological substrate for the pathophysiology of early psychosis and UHR states.     

Adolescents at ultra-high risk of psychosis in Italian neuropsychiatry services: prevalence,psychopathology and transition rate

Studies in adolescents on ultra-high risk (UHR) and basic symptoms (BS) criteria for psychosis prediction are scarce. In Italy, early interventions in psychosis are less widespread than in other European countries. In the present study, we (1) assessed the clinical relevance of a UHR diagnosis [according to the comprehensive assessment of at-risk mental states (CAARMS) criteria] to promote the implementation of specific services for UHR adolescents into the Italian health care system; (2) described severity of positive, negative, general, and basic symptoms in UHR adolescents compared to adolescents with first-episode psychosis (FEP) and non-UHR adolescents (i.e., individuals who did not meet CAARMS criteria for UHR or FEP); and (3) investigated the predictive validity of UHR criteria in relation to BS criteria. Seventy-nine adolescents (aged 13–18 years) were assessed with the CAARMS, the positive and negative syndrome scale (PANSS), and the schizophrenia proneness instrument, child and youth version (SPI-CY). Both UHR (n = 25) and FEP (n = 11) had significantly higher PANSS subscale scores compared to non-UHR (n = 43). UHR had significantly lower PANSS-positive symptom scores than FEP, but similar global functioning and PANSS-negative symptoms and general psychopathology scores. Compared to non-UHR, both FEP and UHR had more severe thought and perception BS disturbances, and significantly more often met BS criteria. After 12 months, 2 of 20 (10%) UHR had transitioned to psychosis. They also met both BS criteria. Given the uncertain outcome of UHR adolescents, future research is needed to determine whether the combined assessment of BS with UHR symptoms can improve the accuracy of psychosis prediction in adolescence.     

Sustained attention in young people at high risk of psychosis does not predict transition to psychosis

Early detection of imminent psychosis allows for the possibility of interventions to prevent onset, or to minimise severity and disability. It also has potential to enhance knowledge of the factors important in the etiology of psychotic illnesses. Neurocognitive deficits are well documented in psychotic illnesses and there is evidence to suggest that such deficits are present in individuals long before they develop the illness. Further, it has been proposed that such impairments may indicate an underlying predisposition to develop psychosis and may thus be described as 'vulnerability indicators'. This study aimed to investigate the proposed vulnerability indicator of impaired sustained attention in young people thought to be at ultra high-risk of developing psychosis imminently to see whether it would improve the prediction of psychosis in this group. The Continuous Performance Test - Identical Pairs (CPT-IP) version performance of an ultra high-risk group (UHR, N=70) was compared with that of a healthy comparison group (NC, N=51) and a first-episode psychosis group (FEP, N=32). The UHR group exhibited performance deficits compared to the NC group and performed at a level similar to that of the FEP group. However, within the UHR group, those who developed psychosis within the timeframe of the study did not differ from those who did not develop psychosis on their CPT-IP performance. These results support sustained attention as an indicator of vulnerability to psychosis, but suggest that CPT-IP performance does not help to predict transition to psychosis in an ultra high-risk group.     

Coping strategies and their relationship to psychopathologies in people at ultra high-risk for psychosis and with schizophrenia

This study's aim was to investigate coping strategies and their relationship to symptoms in people at ultra high risk (UHR) for psychosis compared with recent-onset schizophrenia (SPR) and healthy controls. Thirty-three UHR participants, 22 SPR patients, and 33 healthy controls completed the Ways of Coping Questionnaire and other clinical measures. People at UHR for psychosis showed significantly more reliance on tension-reduction and less reliance on problem-focused coping than healthy controls. The SPR group showed more reliance on tension-reduction coping than healthy controls at a trend level. Maladaptive coping patterns were associated with higher levels of negative symptoms, depression, and anxiety in both the UHR and SPR groups. These findings suggest that maladaptive coping strategies might have already emerged in the (putative) prodromal stage and could influence symptom severities.     

Adhesio interthalamica in individuals at high-risk for developing psychosis and patients with psychotic disorders

Abnormal neurodevelopment in midline structures such as the adhesio interthalamica (AI) has been reported in psychotic disorders, but it is unknown whether individuals at risk for the disorder share the AI findings observed in patients with florid psychosis. Magnetic resonance imaging of 162 patients with first-episode psychosis (FEP), 89 patients with chronic schizophrenia, 135 individuals at ultra high-risk (UHR) of psychosis (of whom 39 later developed psychosis), and 87 healthy controls were used to investigate the length and prevalence of the AI. The relation of the AI length to lateral ventricular enlargement was also explored. The patients with FEP and chronic schizophrenia as well as UHR individuals had a shorter AI than the controls, but there was no difference in the AI findings between the UHR individuals who did and did not subsequently develop psychosis. There was a negative correlation between the AI length and lateral ventricular volume in all the diagnostic groups. The absence of the AI was more common in the chronic schizophrenia patients when compared with all other groups. These results support the notion that the AI absence or shorter length could be a neurodevelopmental marker related to vulnerability to psychopathology, but also suggest that schizophrenia patients may manifest progressive brain changes related to ongoing atrophy of the AI after the onset.     

Evidence-based psychotherapy for the prevention and treatment of first-episode psychosis

The aim of psychotherapy among individuals at clinical high risk (CHR) for psychosis is to prevent transition to full-blown psychosis. Psychotherapy in individuals with a first-episode psychosis (FEP) aims to reduce relapse rates. Remission of (pre-) psychotic symptoms, psychosocial functioning, quality of life, comorbid disorders and self-esteem are also important outcomes in individuals at CHR and with FEP. Antipsychotics, Qmega-3-Fatty acids and psychotherapy have been found to be effective in CHR for most of these aims. Thereby psychotherapy presents a better benefit/risk ratio than antipsychotic medication. The most evidence-based intervention is cognitive-behavioral therapy (CBT). Psychotherapy is mostly offered to FEP patients within specialized early intervention services (including assertiveness community treatment and antipsychotic medication). Thereby, CBT is effective for positive symptoms and family intervention is particularly effective for the prevention of relapses. We introduce the principles of CBT for psychosis and suggest adaptions for individuals at CHR and FEP. We conclude that the needs of young people at CHR and with FEP are best met by specially designed, low threshold outpatient clinical services, which include intensive psychotherapy treatment. A number of countries have implemented early detection and intervention services based on this model, while the implementation within in Germany is still marginal.

     

Gene expression analysis in blood of ultra-high risk subjects compared to first-episode of psychosis patients and controls

Objectives. This study aimed to investigate peripheral blood gene expression in ultra-high-risk subjects (UHR) compared to first-episode psychosis individuals (FEP) and healthy controls (HC). Methods. We enrolled 22 UHR, 66 FEP and 67 HC and investigated the expression of 12 genes using Taqman assays. We used the Univariate General Linear Model, as well as Bonferroni correction for multiple comparisons. Results. We found that UFD1L (ubiquitin fusion degradation 1 like (yeast)) gene was upregulated in UHR group compared to HC and FEP (P = 3.44 × 10^–6 ; P = 9.41 × 10^–6). MBP (myelin basic protein) was downregulated in UHR compared to FEP (P = 6.07 × 10^–6). DISC1 (disrupted in schizophrenia 1) was also upregulated in UHR compared to FEP but lost statistical significance when corrected for age. Conclusions. These genes are directly related to neurodevelopmental processes and have been associated to schizophrenia. Recent findings described that DISC1 overexpression can disrupt MBP expression, thus, we think that these alterations in UHR individuals could be associated with a common process. UFD1L showed a different pattern of expression only for UHR group, suggesting that they can be under an acute endoplasmatic reticulum stress, demanding elevated levels of Ufd1. Further studies can improve knowledge on disease progression and putative targets to preventive strategies.     

A randomized controlled trial of cognitive behavioral therapy for individuals at clinical high risk of psychosis

Background

Symptomatic and functional outcomes in schizophrenia are associated with the duration of untreated psychosis. However, no candidate biomarkers have been adopted in clinical settings. Multichannel near-infrared spectroscopy (NIRS), which can easily and noninvasively measure hemodynamics over the prefrontal cortex, is a candidate instrument for clinical use.

Aims

We intended to explore prefrontal dysfunction among individuals at different clinical stages, including ultra-high-risk (UHR), first-episode psychosis (FEP), and chronic schizophrenia (ChSZ), compared to healthy subjects.

Method

Twenty-two UHR subjects, 27 patients with FEP, 38 patients with ChSZ, and 30 healthy subjects participated. We measured hemodynamic changes during a block-designed letter fluency task using multichannel NIRS instruments.

Results

We found that the activations of the bilateral ventrolateral prefrontal cortex, and the fronto-polar and anterior parts of the temporal cortical regions in the UHR group were lower than those of the controls, but similar to those of the FEP and ChSZ groups. However, the activations in the bilateral dorsolateral prefrontal cortex regions decrease with advancing clinical stage.

Conclusions

To the best of our knowledge, this is the first study directly comparing differences in hemodynamic changes with respect to the 3 clinical stages of psychosis. Furthermore, this study also demonstrates different patterns of impairment according to the progression of clinical stages using NIRS instruments. NIRS measurements for UHR and FEP individuals may be candidate biomarkers for the early detection of the clinical stages of psychosis.     

Coping strategies and social support in old age psychosis

BACKGROUND: According to vulnerability-stress models of psychosis, cognitive and behavioural coping strategies can help mediate the potentially negative effects of daily stressors. The nature, frequency and effectiveness of coping have been studied in people with psychosis under 65 years of age. However, these findings may not generalise to older people with the diagnosis, as the nature of stressors and coping strategies may change with increasing age. This study therefore aimed to explore coping in older patients with psychosis. METHODS: A total of 48 older patients with psychosis (F20-29, ICD-10) and 25 non-clinical elderly controls were compared using self-report measures of stressors, perceived control over stressors, coping strategies, perceived coping efficacy and social support. A regression analysis was used to explore predictors of dysfunctional coping in the patient group. RESULTS: Patients used a significantly higher proportion of problem-focused coping strategies, but they were more dysfunctional copers and rated their coping as less effective compared to controls. They also had fewer friends and less emotional support. Severity of symptoms was a significant predictor of dysfunctional coping when depression, cognitive impairment and functional disability were controlled. CONCLUSIONS: Patients with psychosis coped less well with daily stressors than controls and patients with more severe symptoms were more dysfunctional copers. The findings highlight the potential benefit of psychosocial interventions in old age psychosis.     

Cognitive reserve in patients with first-episode psychosis as outcome predictor at 5-year follow-up

Cognitive reserve (CR) is the premorbid brain capacity to cope with neural damage. People with good CR can tolerate higher levels of pathological brain injuries before displaying clinical symptoms than others. This study aimed to analyze CR in a sample of patients diagnosed with first-episode psychosis (FEP) during childhood or adolescence, comparing them to a community control group (CC) and assessing the predictive value of CR regarding psychosocial functioning, clinical symptoms and neuropsychological variables at the 5-year follow-up. 57 patients diagnosed with FEP during childhood or adolescence and 37 controls completed clinical, neuropsychological, and psychosocial functioning assessments at baseline and 5-year follow-up. CR was assessed in both groups at baseline. The FEP group showed lower CR scores than the CC group. Higher CR in the FEP group was associated with fewer psychotic negative symptoms, total psychotic symptoms and depressive symptoms, higher psychosocial functioning, and less impaired memory and attention at the 5-year follow-up. CR is associated with long-term clinical, neuropsychological and psychosocial functioning outcomes in patients diagnosed with FEP during childhood or adolescence.

     

Group interventions for people with refractory psychosis

Various types of group interventions exist for people with severe mental disorders such as schziophrenia. The content and theoretical backgrounds vary according to the therapeutic goals as well as the clientele targeted. This article describes three group interventions : 1) one aiming at improving self-esteem, 2) one aiming at improving competence through stress management, and 3) one aiming at diminushing distress linked to psychotic symptoms with cognitive behavior therapy. Details on how to conduct these three group interventions, as well as their clinical and theoretical relevance for individuals with refractory psychosis will be described.     

Temperament and character in individuals at ultra-high risk for psychosis and with first-episode schizophrenia: Associations with psychopathology,psychosocial functioning,and aspects of psychological health

Objective

The psychobiological model of temperament and character indicates that personality traits are heritable and, during development, constantly influence one’s susceptibility to schizophrenia. Our objective was to evaluate temperament and character in subjects at ultra-high risk (UHR) for psychosis and individuals with first-episode schizophrenia.

Methods

UHR for psychosis subjects (n = 50), first-episode schizophrenia patients (n = 33), and normal controls (n = 120) were compared on temperament and character dimensions, and correlation analysis of each personality dimension with psychopathologies, global and social functioning, and self-esteem. General and social self-efficacy reports were conducted. UHR subjects were followed-up for 24 months and the baseline personality dimensions were compared between the converted and non-converted groups.

Results

Both clinical groups showed abnormal personality traits in terms of temperament (higher harm avoidance, lower reward dependence and persistence) and character (lower self-directedness and cooperativeness). Psychosocial functioning and psychological health components were found to be correlated with some personality dimensions. The conversion rate of overt psychotic disorder was 25.0% at the 24-month follow-up. Baseline cooperativeness dimension was a significant predictive dimension for conversion into overt psychosis in the UHR group during the follow-up period.

Conclusion

Patients with first episode schizophrenia have a pervasively altered personality profile from normal controls. More importantly, this altered personality profile already emerged in putative prodromal, UHR individuals. The present findings indicate that certain personality traits can play a protective or vulnerable role in developing schizophrenia.     

Interpersonal sensitivity and functioning impairment in youth at ultra-high risk for psychosis

A personality trait that often elicits poor and uneasy interpersonal relationships is interpersonal sensitivity. The aim of the present study was to explore the relationship between interpersonal sensitivity and psychosocial functioning in individuals at ultra-high risk for psychosis as compared to help-seeking individuals who screened negative for an ultra-high risk of psychosis. A total sample of 147 adolescents and young adult who were help seeking for emerging mental health problems participated in the study. The sample was divided into two groups: 39 individuals who met criteria for an ultra-high-risk mental state (UHR), and 108 (NS). The whole sample completed the Interpersonal Sensitivity Measure (IPSM) and the Global Functioning: Social and Role Scale (GF:SS; GF:RS). Mediation analysis was used to explore whether attenuated negative symptoms mediated the relationship between interpersonal sensitivity and social functioning. Individuals with UHR state showed higher IPSM scores and lower GF:SS and GF:RS scores than NS participants. A statistically negative significant correlation between two IPSM subscales (Interpersonal Awareness and Timidity) and GF:SS was found in both groups. Our results also suggest that the relationship between the aforementioned aspects of interpersonal sensitivity and social functioning was not mediated by negative prodromal symptoms. This study suggests that some aspects of interpersonal sensitivity were associated with low level of social functioning. Assessing and treating interpersonal sensitivity may be a promising therapeutic target to improve social functioning in young help-seeking individuals.     

The course of neurocognition and social functioning in individuals at ultra high risk for psychosis

OBJECTIVE: This study evaluates longitudinal neuropsychological performance and its association with clinical symptomatology and psychosocial outcome in individuals identified as ultra high risk (UHR) for psychosis. METHODS: Thirty-five UHR individuals completed neurocognitive, clinical, and social/role functioning assessments at baseline and, on average, 8.3 months later. RESULTS: UHR subjects showed significant cognitive deficits at baseline and 2 distinct profiles of cognitive change over time. On average, 50% demonstrated improvement in social and role functioning over the follow-up period, while the other half showed either stability or decline in functioning. Functional improvement was associated with improved processing speed and visual memory, as well as improvement in clinical symptoms over the follow-up period. In contrast, patients who did not improve functionally showed stable clinical symptoms and cognitive performance over time. CONCLUSIONS: Although the degree of neurocognitive deficit at baseline in UHR patients does not predict psychosocial outcome, the course of neurocognitive change over the first 8 months of follow-up does differentiate patients with good and poor functional outcomes.     

Stress and coping responses to a natural disaster in people with schizophrenia

Investigations of how individuals with schizophrenia differ from non-patients in their responses to stressful life events are subject to the criticism that any between-group differences might merely reflect differences in the types of stressful events that each group experiences. This report presents new analyses of data collected from schizophrenia patients (n=96), bipolar disorder patients (n=18), and healthy controls (n=18) immediately after the Northridge Earthquake that struck Southern California in 1994, a natural experiment that confronted all groups with the same stressful event. Participants completed the Impact of Events Scale (IES; [Horowitz, M.J., Wilner, N., Alvarez, W., 1979. Impact of Events Scale. A measure of subjective stress. Psychosomatic Medicine 41, 209-218]) at 1 week and 5 weeks post-earthquake. At the 5-week follow-up, measures of coping, social support, and self-esteem were also completed. Both patient groups reported higher IES avoidance symptoms than controls immediately after the earthquake. The schizophrenia group also reported lower approach coping, self-esteem, and social support than controls, with the bipolar group reporting intermediate levels. Within the schizophrenia group, higher levels of avoidance coping predicted higher residual stress symptoms at follow-up. Results support the validity of prior reports of altered responses to stressful life events in schizophrenia and demonstrate the clinical relevance of individual differences in coping among affected individuals.     

Cost implications of specific and non-specific treatment for young persons at ultra high risk of developing a first episode of psychosis

Aim: Costs associated with mental health treatment for young persons at ‘ultra’ high risk (UHR) of developing a psychotic disorder have not previously been reported. This paper reports cost implications of providing psychological and pharmacological intervention for individuals at UHR for psychosis compared with minimal psychological treatment. Method: Mental health service costs associated with a randomized controlled trial of two treatments (Specific Preventive Intervention: SPI and Needs‐Based Intervention: NBI) for UHR young persons were estimated and compared at three time points: treatment phase, short‐term follow up and medium‐term follow up. Results: Although the SPI group incurred significantly higher treatment costs than the NBI group over the treatment phase, they incurred significantly lower outpatient treatment costs over the longer term. Conclusion: This study indicates that specific interventions designed to treat young persons who are identified as being at UHR of psychosis might be associated with some cost savings compared with non‐specific interventions.     

Stress abnormalities in individuals at risk for psychosis: A review of studies in subjects with familial risk or with "at risk" mental state

Increased sensitivity to stress is known to play an important role in the transition to first episode psychosis (FEP). Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis, and, in general, an increased sensitivity to stress, have been hypothesised to be components of the vulnerability to psychosis, but whether these abnormalities are already present before the onset of psychosis has not yet been systematically reviewed. Here we have reviewed all studies examining psychological and biological markers of the stress response in the relatives of psychotic patients and in individuals at Ultra High Risk (UHR) for psychosis. In relatives, there is evidence of increased sensitivity to stress, as shown by increased emotional reactivity to daily life stress, increased adrenocorticotropic hormone (ACTH) in response to stress, increased pituitary volume and reduced hippocampal volume. However, evidence of increased cortisol levels is less consistent. On the other hand, subjects who experience attenuated psychotic symptoms show increased cortisol levels as well as increased pituitary and reduced hippocampal volumes. Moreover, this HPA axis hyperactivity seems to be even greater among those individuals who subsequently develop frank psychosis. In summary, an enhanced HPA axis response to stress appears to be part of the biological vulnerability to psychosis which is present prior to the onset of psychosis. A further increase in cortisol levels during the transition to FEP suggests the presence of an additive factor, possibly environmental, at this stage of the illness. Possible causes and consequences of HPA axis impairment in risk for psychosis are discussed.     

Loneliness in psychosis: a systematic review

Purpose

The aim of the review is to understand the relationships between loneliness and related psychological and social factors in individuals with psychosis. Loneliness is poorly understood in people with psychosis. Given the myriad of social challenges facing individuals with psychosis, these findings can inform psychosocial interventions that specifically target loneliness in this vulnerable group.

Methods

We adhered to the PRISMA guidelines and systematically reviewed empirical studies that measured loneliness either as a main outcome or as an associated variable in individuals with psychosis.

Results

A total of ten studies examining loneliness in people diagnosed with a psychotic disorder were examined. Heterogeneity in the assessment of loneliness was found, and there were contradictory findings on the relationship between loneliness and psychotic symptomatology. In individuals with psychosis, loneliness may be influenced by psychological and social factors such as increased depression, psychosis, and anxiety, poor social support, poor quality of life, more severe internalised stigma and perceived discrimination, and low self-esteem.

Conclusions

The relationship between loneliness and psychosis remains poorly understood due to a lack of rigorous studies. Although having strong social relationships is crucial to facilitate recovery from serious mental illness, psychosocial interventions that specifically target loneliness in individuals with psychosis are lacking and sorely needed. Interventions targeting loneliness in those with psychosis will also need to account for additional barriers associated with psychosis (e.g., social skill deficits, impoverished social networks, and negative symptoms).

     

Non-reduction in hippocampal volume is associated with higher risk of psychosis

Previous research using MRI scans has shown reduced hippocampal volumes in chronic schizophrenia and first-episode psychosis compared to well subjects. There are few MRI volumetric studies of high-risk cohorts and no studies that have compared structural measures between high-risk subjects who later developed a psychotic illness and those who did not. Therefore, the question of whether structural changes to the hippocampi precede the onset of an acute psychotic episode has not been answered.Hippocampal and whole brain volumes of 60 people at ultra high-risk (UHR) of developing a psychotic episode (identified through state and trait criteria) were obtained through MRI scan and compared with subjects with first episode psychosis (FEP: n=32), and no mental illness (n=139). Thirty-three percent (n=20) of the UHR cohort developed a psychotic disorder during the 12-month period following the MRI scan.The UHR group as a whole, like the FEP group, had significantly smaller left and right hippocampal volumes than the normal comparison group. Contrary to our initial hypothesis, the left hippocampal volume of the UHR subjects who developed a psychotic disorder was larger than the UHR-non-psychotic subgroup and the FEP group, but no differences were found between the UHR-psychotic and normal groups. The right hippocampus of the UHR-non-psychotic group was significantly smaller than the Normal group but not different to the FEP group. Furthermore, a larger left hippocampal volume of the UHR cohort at intake was associated with the subsequent development of acute psychosis rather than smaller volumes.These results contradicted the expected outcomes, which had been influenced by the neurodevelopmental model of the development of psychosis and an earlier study comparing hippocampal volumes of first episode, chronic schizophrenia and normal populations. One implication of these results is that a process of dynamic central nervous system change may occur during the onset phase of schizophrenia and related disorders, rather than earlier in life as suggested by the neurodevelopmental model. Alternatively, selection factors associated with the UHR cohort may have created a bias in the results. Replication of these results is required in other high-risk cohorts.     

How does social functioning in the early stages of psychosis relate to depression and social anxiety?

Aims: The study aims to compare social functioning in young people considered to be at risk of psychosis with those meeting criteria for first episode psychosis (FEP) and controls, and to determine the association between social functioning and positive and negative symptoms, depressive symptoms, and social anxiety. Methods: This study examined social functioning in 20 individuals at risk of psychosis, 20 FEP patients and 20 healthy controls. Social functioning was measured using the Social Functioning Scale and World Health Organization Disability Assessment Scale. Psychiatric variables were also measured using the Comprehensive Assessment of At‐Risk Mental States, the Brief Psychiatric Rating Scale, the Brief Social Phobia Scale, and the Depression Anxiety and Stress Scale. Results: At‐risk individuals had comparable social deficits to the FEP group, and both patient groups had significantly poorer social functioning than controls. Importantly, social functioning was most strongly associated with depressive and social anxiety symptoms and to a lesser extent with positive symptoms. However, negative symptoms did not appear to relate to social functioning. Conclusion: Social functioning impairments precede the onset of full‐threshold psychosis and may therefore be a significant marker for the illness. Additionally, associated psychiatric symptoms such as depression and social anxiety may provide an avenue for early interventions of social functioning deficits in psychosis.
