Abstract
Social cognition (SC) and executive function (EF) have been described as important variables for social functioning and recovery of patients with psychosis. However, the relationship between SC and EF in first-episode psychosis (FEP) deserves further investigation, especially focusing on gender differences. AIMS To investigate the relationship between EF and different domains of SC in FEP patients and to explore gender differences in the relationship between these domains. METHODS A cross-sectional study of 191 patients with new-onset psychosis recruited from two multicenter clinical trials. A comprehensive cognitive battery was used to assess SC (Hinting Task, Face Test and IPSAQ) and EF (TMT, WSCT, Stroop Test and digit span - WAIS-III). Pearson correlations and linear regression models were performed. RESULTS A correlation between Theory of Mind (ToM), Emotional Recognition (ER) and EF was found using the complete sample. Separating the sample by gender showed different association profiles between these variables in women and men. CONCLUSIONS A relationship between different domains of SC and EF is found. Moreover, women and men presented distinct association profiles between EF and SC. These results should be considered in order to improve the treatment of FEP patients and designing personalized interventions by gender.

Abstract
This systematic review provides a comprehensive overview of the association between premorbid adjustment and social cognition in people with psychotic spectrum disorder. Obtaining evidence of this association will facilitate early detection and intervention before the onset of psychosis. Literature searches were conducted in Scopus, PubMed and PsycINFO. Studies were eligible if they included patients with a psychotic disorder or at a high-risk state; social cognition and premorbid adjustment were measured; and the relationship between premorbid adjustment and social cognition was analysed. The authors independently extracted data from all included articles, and discrepancies were resolved through discussion. Literature searches were conducted in Scopus, PubMed and PsycINFO. Studies were eligible if they included patients with a psychotic disorder or at a high-risk state; social cognition and premorbid adjustment were measured; and the relationship between premorbid adjustment and social cognition was analysed. The authors independently extracted data from all included articles, and discrepancies were resolved through discussion. Of 229 studies identified, 23 met the inclusion criteria. Different methods of assessment were used to measure premorbid adjustment, such as the Premorbid Adjustment Scale or premorbid IQ, among others. Social cognition was assessed as a global measure or by domains using different instruments. A total of 16 articles found a relationship between social cognition (or its domains) and premorbid adjustment: general social cognition (n = 3); Theory of Mind (n = 12); Emotional Recognition and Social Knowledge (n = 1). This review shows evidence of a significant relationship between social cognition and premorbid adjustment, specifically between Theory of Mind and premorbid adjustment. Social cognition deficits may already appear in phases prior to the onset of psychosis, so an early individualized intervention with stimulating experiences in people with poor premorbid adjustment can be relevant for prevention. We recommend some future directions, such as carrying out longitudinal studies with people at high-risk of psychosis, a meta-analysis study, broadening the concept of premorbid adjustment, and a consensual assessment of social cognition and premorbid adjustment variables. PROSPERO registration number: CRD42022333886.

Role of adenosine A2A receptors in hot and cold cognition: Effects of single-dose istradefylline in healthy volunteers. Eur Neuropsychopharmacol 2023; 71:55-64. [PMID: 36989539 DOI: 10.1016/j.euroneuro.2023.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 03/03/2023] [Accepted: 03/07/2023] [Indexed: 03/31/2023]
Abstract
The role of the adenosine neurochemical system in human cognition is under-studied, despite such receptors being distributed throughout the brain. The aim of this study was to shed light on the role of the adenosine A2A receptors in human cognition using single-dose istradefylline. Twenty healthy male participants, aged 19-49, received 20 mg istradefylline and placebo, in a randomized, double-blind, placebo-controlled cross-over design. Cognition was assessed using computerized cognitive tests, covering both cold (non-emotional) and hot (emotion-laden) domains. Cardiovascular data were recorded serially. Cognitive effects of istradefylline were explored using repeated measures analysis of variance and paired t-tests as appropriate. On the EMOTICOM battery, there was a significant effect of istradefylline versus placebo on the Social Information Preference task (t = 2.50, p = 0.02, d=-0.59), indicating that subjects on istradefylline interpreted social situations more positively. No other significant effects were observed on other cognitive tasks, nor in terms of cardiovascular measures (pulse and blood pressure). De-briefing indicated that blinding was successful, both for participants and the research team. Further exploration of the role of adenosine A2A receptors in emotional processing may be valuable, given that abnormalities in related cognitive functions are implicated in neuropsychiatric disorders. The role of adenosine systems in human cognition requires further clarification, including with different doses of istradefylline and over different schedules of administration.

Abstract
BACKGROUND AND OBJECTIVES Rather than focusing on the extensively studied social perception and recognition impairments in people with schizophrenia, this study focuses on the type of social information considered relevant by people with schizophrenia, and how they use it to arrive at conclusions about social situations. METHODS Participants included 50 outpatients with schizophrenia from the Hospital del Salvador at Valparaíso, Chile, and 50 healthy comparators matched by age and gender. Subjects completed the Social Information Preference Test (SIPT), which presents scenes depicting ambiguous social situations with faces, thoughts, and facts about the scene hidden from view. Participants were required to select a limited number of these items and then choose between possible interpretations of the scene (positive, neutral, or negative). Additionally, they are asked to provide a feeling of certainty in their answers, using a 7-point visual analogue scale. RESULTS People with schizophrenia, as well as controls had a strong preference for knowing the thoughts of the characters. Both groups were least likely to choose emotional expressions. Patients were significantly less likely to choose object/information than controls. Both groups showed a high certainty in their responses and no tendency to choose negative interpretations. LIMITATIONS compensated clinical status of the patients may have influenced the results. CONCLUSIONS The results of this study suggest that, despite difficulties perceiving clues about the mental state of others, people with schizophrenia use this information to make sense of social situations, and apparently, they do not have problems in understanding social interactions.

Abstract
Subjects with first-episode psychosis experience substantial deficits in social cognition and metacognition. Although previous studies have investigated the role of profiles of individuals in social cognition and metacognition in chronic schizophrenia, profiling subjects with first-episode psychosis in both domains remains to be investigated. We used latent profile analysis to derive profiles of the abilities in 174 persons with first-episode psychosis using the Beck's Cognitive Insight Scale, the Faces Test, the Hinting Task, the Internal, Personal and Situational Attributions Questionnaire, and the Beads Task. Participants received a clinical assessment and a neuropsychological assessment. The best-fitting model was selected according to the Bayesian information criterion (BIC). We assessed the importance of the variables via a classification tree (CART). We derived three clusters with distinct profiles. The first profile (33.3%) comprised individuals with low social cognition. The second profile (60.9%) comprised individuals that had more proneness to present jumping to conclusions. The third profile (5.7%) presented a heterogeneous profile of metacognitive deficits. Persons with lower social cognition presented worse clinical and neuropsychological features than cluster 2 and cluster 3. Cluster 3 presented significantly worst functioning. Our results suggest that individuals with FEP present distinct profiles that concur with specific clinical, neuropsychological, and functional challenges. Each subgroup may benefit from different interventions.

[PMID: 33679460 PMCID: PMC7935547 DOI: 10.3389/fpsyt.2020.596625] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 12/28/2020] [Indexed: 11/21/2022] Open
Abstract
Introduction: Cognitive biases are key factors in the development and persistence of delusions in psychosis. The Cognitive Biases Questionnaire for Psychosis (CBQp) is a new self-reported questionnaire of 30 relevant situations to evaluate five types of cognitive biases in psychosis. In the context of the validation of the Spanish version of the CBQp, our objectives were to (1) analyze the factorial structure of the questionnaire with a confirmatory factor analysis (CFA), (2) relate cognitive biases with a widely used scale in the field of delusion cognitive therapies for assessing metacognition, specifically, Beck's Cognitive Insight Scale (BCIS) (1), and, finally, (3) associate cognitive biases with delusional experiences, evaluated with the Peters Delusions Inventory (PDI) (2). Materials and Methods: An authorized Spanish version of the CBQp, by a translation and back-translation procedure, was obtained. A sample of 171 patients with different diagnoses of psychoses was included. A CFA was used to test three different construct models. Associations between CBQp biases, the BCIS, and the PDI were made by correlation and mean differences. Comparisons of the CBQp scores between a control group and patients with psychosis were analyzed. Results: The CFA showed comparative fit index (CFI) values of 0.94 and 0.95 for the models with one, two, and five factors, with root mean square error of approximation values of 0.031 and 0.029. The CBQp reliability was 0.87. Associations between cognitive biases, self-certainty, and cognitive insight subscales of the BCIS were found. Similarly, associations between total punctuation, conviction, distress, and concern subscales of the PDI were also found. When compared with the group of healthy subjects, patients with psychoses scored significantly higher in several cognitive biases. Conclusion: Given the correlation between biases, a one-factor model might be more appropriate to explain the scale's underlying construct. Biases were associated with a greater frequency of delusions, distress, conviction, and concern as well as worse cognitive insight in patients with psychosis.

Abstract
Abstract
Background
This study investigated whether self-reported cognitive functions (i.e. task orientation, distractibility, persistence, flexibility, and perseverance) predict the trajectory of paranoid ideation over a 15-year prospective follow-up in adulthood.
Methods
The participants came from the population-based Young Finns study (N = 1210‒1213). Paranoid ideation was assessed with the Paranoid Ideation Scale of the Symptom Checklist-90 Revised (SCL-90R) in 1997, 2001, 2007, and 2012. Self-reported cognitive functions were evaluated in 1997 with the Task orientation, Distractibility, Persistence, and Flexibility scales of the DOTS-R (the Revised Dimensions of Temperament Survey) and the Perseverance scale of the FCB-TI (the Formal Characteristics of Behaviour – Temperament Inventory). The data was analyzed using growth curve models that were adjusted for age, sex, and socioeconomic factors in childhood and adulthood.
Results
Low self-reported task orientation, low persistence, high distractibility, low flexibility, and high perseverance predicted higher level of paranoid ideation over the 15-year follow-up.
Conclusions
Self-reported cognitive functions seem to predict paranoid ideation over a long-term follow-up. Promoting cognitive functions in early interventions may have long-term protective influences against the development of paranoid ideation in non-clinical populations.

Abstract
BACKGROUND AND OBJECTIVES Rather than focusing on the extensively studied social perception and recognition impairments in people with schizophrenia, this study focuses on the type of social information considered relevant by people with schizophrenia, and how they use it to arrive at conclusions about social situations. METHODS Participants included 50 outpatients with schizophrenia from the Hospital del Salvador at Valparaíso, Chile, and 50 healthy comparators matched by age and gender. Subjects completed the Social Information Preference Test (SIPT), which presents scenes depicting ambiguous social situations with faces, thoughts, and facts about the scene hidden from view. Participants were required to select a limited number of these items and then choose between possible interpretations of the scene (positive, neutral, or negative). Additionally, they are asked to provide a feeling of certainty in their answers, using a 7-point visual analogue scale. RESULTS People with schizophrenia, as well as controls had a strong preference for knowing the thoughts of the characters. Both groups were least likely to choose emotional expressions. Patients were significantly less likely to choose object/information than controls. Both groups showed a high certainty in their responses and no tendency to choose negative interpretations. LIMITATIONS compensated clinical status of the patients may have influenced the results. CONCLUSIONS The results of this study suggest that, despite difficulties perceiving clues about the mental state of others, people with schizophrenia use this information to make sense of social situations, and apparently, they do not have problems in understanding social interactions.

Abstract
While social cognition (SC) is widely recognized as being impaired in schizophrenia, little is known about the potential heterogeneity in individuals' functioning. Using a wide range of SC measures and a cluster-analytic approach, we compared SC profiles in the general population and in people with schizophrenia. A total of 131 healthy controls and 101 participants with schizophrenia were included. Groups were compared on sociodemographic, neurocognition, anxiety and depressive mood variables. Three profiles were identified in healthy controls: one with good SC abilities (Homogeneous SC group) and two with specific weaknesses in complex Facial Emotion Recognition (Low FER group) or Affective Theory of Mind (Low AToM group). However, these patterns were not found in participants with schizophrenia, who were characterized rather by levels of SC functioning (i.e., Low, Medium and High SC groups). Importantly, while the High SC group (47.9% of the sample) exhibited normal performances, the two others were underpinned by different pathological processes (i.e., alexithymia for Medium SC group or neurocognition dysfunctioning for Low SC group). These results have important implications for future research as well as for clinical practice regarding assessment methodology and therapeutic interventions.

Murphy P, Bentall RP, Freeman D, O'Rourke S, Hutton P. The paranoia as defence model of persecutory delusions: a systematic review and meta-analysis. Lancet Psychiatry 2018; 5:913-929. [PMID: 30314852 DOI: 10.1016/s2215-0366(18)30339-0] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2018] [Revised: 08/23/2018] [Accepted: 08/29/2018] [Indexed: 11/29/2022]
Abstract
BACKGROUND An influential psychological model of persecutory delusions proposed that they are caused by a bias towards holding others responsible for negative events (an externalising attributional bias), preventing the individual from becoming aware of underlying low self-esteem. An early version of the model predicted self-esteem would, therefore, be preserved in people with these delusions, but a later version suggested it would be unstable, and that there would be a discrepancy between explicit and implicit self-esteem, with the latter being lower. We did a comprehensive meta-analytical test of the key predictions of this model and assessed the quality of evidence. METHODS We searched PubMed from Jan 1, 1994, to July 31, 2018, and collated systematic reviews of the defensive model's predictions in relation to persecutory delusions. We also searched PsycINFO, MEDLINE, Embase, and Web of Science for articles published from Jan 1, 2012, to Sept 10, 2016. Cross-sectional data from case-control, longitudinal, or experimental studies that examined self-esteem or the externalising attributional bias in individuals diagnosed as having schizophrenia-spectrum disorder were eligible for meta-analyses of group differences if at least 50% of participants with psychosis also had current persecutory delusions. Uncontrolled and longitudinal studies were included in meta-analyses of correlations and self-esteem instability, respectively. Study and outcome quality were assessed with the Agency for Healthcare Research and Quality assessment tool, and a modified version of Grading of Recommendations Assessment, Development and Evaluation, respectively. The study protocol is registered with PROSPERO, number CRD42016032782. FINDINGS We screened 3053 records, examined 104 full-text reports, and included 64 eligible studies. Consistent with the predictions of both versions of the model, paranoia severity in psychosis was positively correlated with the degree of externalising attributional bias (21 studies involving 1128 individuals; r=0·18, 95% CI 0·08 to 0·27, with moderate quality evidence). People with persecutory delusions also had a greater externalising attributional bias than non-clinical individuals (27 studies involving 1442 individuals; g=0·48, 95% CI 0·23 to 0·73) and depressed individuals (ten studies involving 421 individuals; g=1·06, 0·48 to 1·63), and people with psychosis without persecutory delusions (11 studies involving 480 individuals; g=0·40, 0·12 to 0·68), all based on moderate quality evidence. Contrary to the predictions in the early version of the model, paranoia severity in psychosis was negatively correlated with explicit self-esteem (23 studies involving 1866 individuals; r=-0·26, 95% CI -0·34 to -0·17, with high quality evidence). People with persecutory delusions also had lower explicit self-esteem than non-clinical individuals (22 studies involving 1256 individuals; g=-0·88, 95% CI -1·10 to -0·66, with high quality evidence) and explicit self-esteem similarly low to that in people with psychosis without persecutory delusions (11 studies involving 644 individuals; g=-0·26, -0·54 to 0·02, with moderate quality evidence). Consistent with the predictions in the later version of the model, self-esteem instability was positively correlated with paranoia severity in psychosis (four studies involving 508 individuals; r=0·23, 95% CI 0·11-0·34, with high quality evidence), and people with persecutory delusions had a greater discrepancy between their implicit and explicit self-esteem than depressed individuals (seven studies involving 398 individuals; g=0·61, 95% CI 0·37 to 0·85, with moderate quality evidence). They had higher explicit self-esteem than depressed individuals (13 studies involving 647 individuals; g=0·89, 95% CI 0·51 to 1·28, with moderate quality evidence), but similarly low implicit self-esteem (seven studies involving 398 individuals; g=-0·19, -0·45 to 0·07, with low quality evidence). In contrast to the later predictions, people with persecutory delusions did not have a greater self-esteem discrepancy than non-clinical individuals (ten studies involving 592 individuals; g=-0·17, 95% CI -0·45 to 0·12), although the evidence was very low quality. People with psychosis with or without persecutory delusions did not differ for implicit self-esteem (four studies involving 167 individuals; g=-0·24, 95% CI -0·77 to 0·30, with low quality evidence) or self-esteem discrepancies (four studies involving 165 individuals; g=0·17, -0·19 to 0·53, with moderate quality evidence). INTERPRETATION The predictions that self-esteem would be preserved in people with persecutory delusions in the early version of the paranoia as defence model and that implicit-explicit self-esteem discrepancy would be greater in people with persecutory delusions than in non-clinical individuals and people with psychosis without persecutory delusions in the later version of the model were not supported. By contrast, the later version correctly predicted that people with persecutory delusions have a greater self-esteem discrepancy than people with depression and a greater externalising attributional bias than all control groups, and that both this bias and self-esteem instability are associated with increased paranoia severity. Nevertheless, the reviewed data had limitations. Experimental studies, which might include interventionist-causal trials, are needed. FUNDING None.

Abstract
BACKGROUND We validated the Social Mistrust Scale (SMS) and utilized it to examine the structure, prevalence, and heritability of social mistrust in a large sample of Chinese children and adolescents. METHODS In Study 1, a large sample of healthy twins (N=2094) aged 8 to 14years (M=10.27years, SD=2) completed the SMS. Structural equation modeling (SEM) was conducted to assess the structure of the SMS and to estimate the heritability of social mistrust in a sub-sample of twins (n=756 pairs). In Study 2, 32 adolescents with childhood-onset schizophrenia were compared with 34 healthy controls on levels of suspiciousness and clinical symptoms to examine the associations between the SMS and the Positive and Negative Syndrome Scale (PANSS). RESULTS We found a three-factor structure for social mistrust (home, school, and general mistrust). Social mistrust was found to be moderately - heritable (19%-40%), with mistrust at home most strongly influenced by genetic factors. Compared with 11.76% of the healthy controls, 56.25% of the adolescents with early-onset schizophrenia exhibited very high levels of social mistrust on all three subscales of the SMS. The SMS exhibited good discriminant validity in distinguishing adolescents with childhood-onset schizophrenia from healthy controls and showed associations with a broad range of symptoms assessed by the PANSS. CONCLUSIONS Social mistrust assessed by the SMS may be heritable. The SMS demonstrates good discriminant validity with clinical diagnoses of schizophrenia. However, it seems to be correlated with multiple aspects of psychopathology in the schizophrenia group, rather than being specific to delusional ideation/paranoia.

Abstract
BACKGROUND Aberrant attributional styles are counted to a set of circumscribed cognitive biases that are implicated in the pathogenesis of (paranoid) psychosis. However, evidence for a specific profile (e.g., an exaggerated self-serving bias, other-blaming bias) has become equivocal over the years. More recently, one-sided (monocausal) attributions have been reported in patients with psychosis. METHODS We compared a large sample of patients with diagnosed schizophrenia (n=145) to nonclinical controls (n=30) on a revised version of the Internal, Personal and Situational Attributions Questionnaire (IPSAQ-R). In this task, participants have to assign probability estimates to each of three potential causes (i.e., myself, others, circumstances) for a specific (negative or positive) event. RESULTS Participants with schizophrenia displayed an abolished self-serving bias and showed a significant preference for one-sided/monocausal attributions, which was neither correlated with jumping to conclusions nor overconfidence in errors. School education correlated with less monocausal attributions. We did not find any congruence between attributional styles with core delusional ideas. CONCLUSIONS Our study corroborates earlier investigations showing that monocausal attributions may play a role in the pathogenesis of psychosis; this bias unlikely represents an epiphenomenon of established biases. Unexpectedly, attributional styles (e.g., external-blaming) did not shape delusional contents. The true prevalence of monocausal attributions in psychosis is perhaps underestimated in the study, as groups were equated on school education, which was correlated with monocausal attributions.

Abstract
BACKGROUND Schizophrenia patients present deficits in social cognition (SC), emotion and social perception, theory of mind (ToM), and attributional style. This study tested the efficacy, in real clinical conditions, of a online self-training program in SC, e-Motional Training®, in comparison with treatment as usual. METHOD A randomized single-blinded multicenter clinical trial was conducted with 60 schizophrenia stable outpatients. All patients (control and intervention) were treated with drug therapy, case management, and individual and group psychotherapy (not focused on SC). Intervention group was treated with e-Motional Training®, an online program devised for SC rehabilitation. STATISTICAL ANALYSIS A descriptive analysis and parametric/non-parametric tests were used to compare both groups at baseline. Analysis of covariance was used to compared post-pre changes in SC between the two interventions. If the group effect was significant, follow-up univariate test (t-test for dependent samples) was carried out in each group to verify whether the effect was due to improvement in the intervention group or deterioration in the control group. We considered statistically significant differences with P < 0.05. RESULTS Significant improvements were obtained in the intervention group in emotion recognition and most ToM variables in comparison with the control group. DISCUSSION e-Motional Training® seems to be a promising online training tool for SC deficits in schizophrenia, covering the lack of similar intervention instruments in our community.

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.

Impaired self-agency inferences in schizophrenia: The role of cognitive capacity and causal reasoning style. Eur Psychiatry 2017; 47:27-34.

Abstract
BACKGROUND The sense of self-agency, i.e., experiencing oneself as the cause of one's own actions, is impaired in patients with schizophrenia. Normally, inferences of self-agency are enhanced when actual outcomes match with pre-activated outcome information, where this pre-activation can result from explicitly set goals (i.e., goal-based route) or implicitly primed outcome information (i.e., prime-based route). Previous research suggests that patients show specific impairments in the prime-based route, implicating that they do not rely on matches between implicitly available outcome information and actual action-outcomes when inferring self-agency. The question remains: Why? Here, we examine whether neurocognitive functioning and self-serving bias (SSB) may explain abnormalities in patients' agency inferences. METHODS Thirty-six patients and 36 healthy controls performed a commonly used agency inference task to measure goal- and prime-based self-agency inferences. Neurocognitive functioning was assessed with the Brief Assessment of Cognition in Schizophrenia (BACS) and the SSB was assessed with the Internal Personal and Situational Attributions Questionnaire. RESULTS Results showed a substantial smaller effect of primed outcome information on agency experiences in patients compared with healthy controls. Whereas patients and controls differed on BACS and marginally on SSB scores, these differences were not related to patients' impairments in prime-based agency inferences. CONCLUSIONS Patients showed impairments in prime-based agency inferences, thereby replicating previous studies. This finding could not be explained by cognitive dysfunction or SSB. Results are discussed in the context of the recent surge to understand and examine deficits in agency experiences in schizophrenia.

Abstract
BACKGROUND AND OBJECTIVES The ability to integrate evidence into a reasoning process is crucial in order to react to changing information, e.g. to adapt one's beliefs according to new evidence or to generate new beliefs when facing better alternatives. Evidence integration ability is thus associated with belief flexibility. A specific bias of evidence integration, a bias against disconfirmatory evidence (BADE), can be found in patients with schizophrenia and has been linked to delusion development and maintenance. Knowledge about whether the BADE occurs already in risk constellations of psychosis can clarify its role in the pathogenesis of psychosis. METHODS This article reviews the current literature on BADE. Many studies demonstrate BADE over the course of illness, ranging from healthy controls with subclinical properties of schizotypy, over patients with at-risk mental states (ARMS) and patients with a first episode of psychosis to patients with chronic schizophrenia. These data allow a comparison of competences and deficits over the course of illness. Underlying mechanisms of BADE are discussed, including interrelations with neurocognitive performance and dopaminergic processes. RESULTS The BADE could be found in different phases of psychosis development and can be regarded as a cognitive marker of the beginning psychotic state. LIMITATIONS The presented findings are derived from independent cross-sectional studies. So far, no comprehensive longitudinal assessment has been published. CONCLUSIONS Treatments of metacognitive deficits in general and as early as in the ARMS might interfere with the cognitive pathogenesis of psychosis, and thereby ameliorate, postpone or even prevent the transition to psychosis.

Abstract
BACKGROUND Appraisals are suggested to play a determining role in the clinical outcome of psychotic experiences (PEs). We used experimental tasks that mimic PEs to investigate appraisals in individuals with PEs with and without a 'need-for-clinical-care', and psychosis patients whose symptoms have remitted. We predicted that patients would appraise the tasks as threatening regardless of current symptom level, while non-clinical and control groups would appraise them as non-threatening. METHOD Appraisals following three anomalous experiences-inducing tasks [Telepath, Cards task, Virtual acoustic space paradigm (VASP)] were examined in 71 individuals: symptomatic (n = 18) and remitted (n = 16) psychosis patients; non-clinical group with PEs (n = 16); controls without PEs (n = 21). RESULTS As predicted, symptomatic patients endorsed more threatening appraisals for all tasks than non-clinical and control groups, who did not differ from each other. However, remitted patients were less likely to endorse threatening appraisals of the Cards and Telepath than their symptomatic counterparts, although they did not differ in global ratings of how striking, threatening and distressing they found the tasks. Moreover, remitted participants endorsed more threatening appraisals of the Telepath and VASP than non-clinical participants, and of the VASP than controls. Remitted participants also rated all three tasks as globally more threatening than the non-clinical group and controls. CONCLUSIONS Clinical outcome may not necessarily be driven by the presence of symptoms, with threatening appraisals of PEs representing a key factor. The remitted group's intermediate appraisal scores imply that the relationship between appraisal and clinical outcome is not straightforward, and potential mediating factors need to be determined.

Abstract
In social interaction, Theory of Mind (ToM) enables us to construct representations of others' mental states, and to use those representations flexibly to explain or predict others' behavior. Although previous literature has documented that schizophrenia is associated with poor ToM ability, little is known about the cognitive mechanisms underlying their difficulty in ToM use. This study developed a new methodology to test whether the difficulty in false-belief-use might be related to deficits in perspective-switching or impaired inhibitory control among 23 remitted schizophrenia patients and 18 normal controls. Patients showed a significantly greater error rate in a perspective-switching condition than a perspective-repeating position in a false-belief-use task, whereas normal controls did not show a difference between the two conditions. In addition, a larger main effect of inhibition was found in remitted schizophrenia patients than normal controls in both a false-belief-use task and control task. Thus, remitted schizophrenia patients' impairment in ToM use might be accounted for, at least partially, by deficits in perspective-switching and impaired inhibitory control.
