Background: Children of parents with severe mental illness report bullying more often compared with controls. We hypothesized that deviations in attributional styles may explain the increased prevalence of bullying experiences. We aimed to assess real-time responses to standardized ambiguous social situations, bullying experiences by children, their primary caregivers, and teachers, and to investigate potential associations between attributional styles and bullying., Method: The study included 465 children aged 11-12, born to parents with schizophrenia, N =179, bipolar disorder, N = 105, or population-based controls, N = 181. Attributional style was evaluated using virtual reality environments depicting ambiguous social everyday situations. We created a tailored assessment since no suitable assessments were found. Bullying was assessed through self-reports and reports from primary caregivers and teachers., Results: We observed no group differences in the attributional style of the children. Reports from children, primary caregivers, and teachers revealed that compared with controls, children born to parents with schizophrenia were more likely to perceive bullying victimization, with high consistency among reports. No associations were found between bullying reports and attributional style., Conclusions: Children of parents with schizophrenia consistently experienced more bullying, as reported by the children themselves, primary caregivers, and teachers. No differences in attributional style were found, indicating that attributional style did not explain the increased prevalence of bullying reports. While it cannot be ruled out that our virtual environments were insufficient to trigger a sense of social exclusion, the results suggest that the observed differences in reported bullying are genuine and not a result of the child's attributional style., Competing Interests: Declaration of competing interest All authors declare no conflict of interest., (Copyright © 2024 Elsevier B.V.

Although social cognitive impairments are evident in patients with schizophrenia across many cultures, psychosocial interventions are less used in Eastern countries. Despite a growing emphasis on community care in mental health services in Eastern countries, the synergistic effects of social cognitive intervention strategies on routine community mental health services are not well documented. This study aimed to adapt a group-based social cognitive skills training (SCST) program for use in a Korean context and evaluate its feasibility and preliminary effects among community-dwelling individuals with schizophrenia. Forty-seven patients were assigned to either the SCST + treatment as usual (TAU) group (n = 21) or the TAU only group (n = 24). Participants completed tasks to assess social cognition, social functioning, neurocognition, and psychiatric symptoms before and after treatment. Over a period of approximately 12 weeks, drop-out rates were comparably low in both groups, and the attendance rates for the SCST program were high (85.7 %, mean sessions attended = 20.56/24 sessions). The SCST + TAU group demonstrated significant improvements in facial affect recognition, social functioning, and psychiatric symptoms compared to the TAU only group. A non-significant trend in theory of mind was observed, along with no improvements in social perception and neurocognition. The adapted version of the SCST program is feasible for implementation and demonstrates promise for enhancing social cognition and functioning in Korean outpatients with schizophrenia., (Copyright © 2020 Elsevier B.V.

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., (Copyright © 2017.

Objective: Social cognition is recognized to be a deficit in individuals suffering from schizophrenia. Numerous studies have explored the relationship between social cognition and social functioning in outpatients with schizophrenia through the use of different social cognition training programs. This study examines the efficacy of the Social Cognition Training Program (PECS in Spanish) in adults with a diagnosis of schizophrenia., Methods: Data were derived from a sample of 44 non-hospitalized adult patients who presented with a DSM-IV-TR Axis I diagnosis of schizophrenia and 39 healthy controls. The 44 patients were divided into an experimental group (n=20) and a control task group (n=24) that received cognitive training. Healthy controls did not receive any treatment. Sociodemographic and clinical variables correlates were computed. The 2-way ANOVA was conducted to examine differences between groups in pre- and post-treatment measures. Intragroup differences were explored using the paired-samples t-test., Results: At the end of the training, patients in the experimental group showed a higher performance compared to patients in the control task group in the Hinting Task Test and in the emotion recognition of sadness, anger, fear, and disgust., Conclusions: The PECS proved to be effective in the improvement of some areas of theory of mind and emotion recognition in outpatients with schizophrenia. The PECS is one of the first programs developed in Spanish to train social cognition, and the data obtained support the importance of expanding the social cognition programs to non-English language samples.

Background: Social-cognitive deficits have a significant impact on the community and vocational functioning of persons with schizophrenia., Objective: This study aimed to explore the relationship between social-cognitive abilities and vocational functioning in a Chinese population., Method: We recruited 30 outpatients with schizophrenia to participate. We administered the Chinese Social Cognition and Screening Questionnaire (C-SCSQ) to assess Theory of Mind (ToM), attributional bias, and neurocognition; the Facial Expression Identification Test (FEIT) to assess emotion perception (EP) ability, and the Chinese Work Personality Profile (CWPP) to assess work performance in a simulated work setting., Results: ToM showed a significant negative correlation with attributional bias. The neurocognitive measure displayed a significant positive correlation with ToM and EP. The structural equation model was a good fit to the data (CFI=0.91, RMSEA=0.12), and showed that social-cognitive abilities had a significant impact (-0.41) on work performance. Of the four social-cognitive domains, ToM and paranoid attributional style (PAS) contributed significantly to variations in work performance. These results support the theory that social-cognitive abilities have an impact on work performance. ToM has a positive impact whereas PAS has an adverse effect., Conclusion: Persons with schizophrenia present specific deficits in their social-cognitive abilities, which have significant impact on their work performance and employability.

Introduction: A preliminary cognitive model of grandiose delusions has been put forward suggesting that persecutory and grandiose delusions shared distinct, yet overlapping psychological processes. This study aims to test this model and hypothesises that participants experiencing grandiose delusions may demonstrate a theory of mind (ToM) impairment and differences in attributional style compared to a control group., Methods: A cross-sectional design compared the performance of 18 individuals with grandiose delusions to a control group of 14 participants with depression. ToM was measured using a non-verbal joke appreciation task and a verbal stories task. Attributional style was measured using the internal, personal and situational attributions questionnaire., Results: Participants experiencing grandiose delusions performed significantly worse on both ToM tasks compared to controls. Furthermore, these participants provided significantly more atypical answers when explaining the joke behind the ToM cartoons. No differences for subjective funniness ratings or attributional style were found., Conclusions: This preliminary study indicated participants experiencing grandiose delusions have ToM impairments which may contribute to the maintenance of this symptom.

Theoretical models postulate an important role of attributional style (AS) in the formation and maintenance of persecutory delusions and other positive symptoms of schizophrenia. However, current research has gathered conflicting findings. In a cross-sectional design, patients with persistent positive symptoms of schizophrenia (n = 258) and healthy controls (n = 51) completed a revised version of the Internal, Personal and Situational Attributions Questionnaire (IPSAQ-R) and assessments of psychopathology. In comparison to controls, neither patients with schizophrenia in general nor patients with persecutory delusions (n = 142) in particular presented an externalizing and personalizing AS. Rather, both groups showed a "self-blaming" AS and attributed negative events more toward themselves. Persecutory delusions were independently predicted by a personalizing bias for negative events (beta = 0.197, P = .001) and by depression (beta = 0.152, P = .013), but only 5% of the variance in persecutory delusions could be explained. Cluster analysis of IPSAQ-R scores identified a "personalizing" (n = 70) and a "self-blaming" subgroup (n = 188), with the former showing slightly more pronounced persecutory delusions (P = .021). Results indicate that patients with schizophrenia and patients with persecutory delusions both mostly blamed themselves for negative events. Nevertheless, still a subgroup of patients could be identified who presented a more pronounced personalizing bias and more severe persecutory delusions. Thus, AS in patients with schizophrenia might be less stable but more determined by individual and situational characteristics that need further elucidation., (© The Author 2014.

Accumulated evidence suggests that Social Cognition and Interaction Training (SCIT) is associated with improved performance in social cognition and social skills in patients diagnosed with psychotic disorders. The current study examined the clinical utility of SCIT in patients with schizophrenia in Chinese community settings. Adults with stable schizophrenia were recruited from local community health institutions, and were randomly assigned to SCIT group (n = 22) or a waiting-list control group (n = 17). The SCIT group received the SCIT intervention plus treatment-as-usual, whereas the waiting-list group received only treatment-as-usual during the period of the study. All patients were administered the Chinese versions of the Personal and Social Performance Scale (PSP), Face Emotion Identification Task (FEIT), Eyes task, and Attributional Style Questionnaire (ASQ) at baseline of the SCIT treatment period and at follow-up, 6 months after completion of the 20-week treatment period. Patients in SCIT group showed a significant improvement in the domains of emotion perception, theory of mind, attributional style, and social functioning compared to those in waiting-list group. Findings indicate that SCIT is a feasible and promising method for improving social cognition and social functioning among Chinese outpatients with stable schizophrenia., (© 2013 Elsevier Ireland Ltd.

Social cognition is often aberrant or impaired in psychotic disorders and related to functional outcomes. In particular, one core social cognitive bias – hostile attribution bias – is proposed to be implicated in paranoia, anxiety, mood disturbances and interpersonal conflict outcomes. However, questions remain about this domain's specificity to psychosis and its relationship to general functional outcomes. The present paper offers a descriptive and critical review of the literature on hostile attribution bias in psychotic disorders, in order to examine (1) its impact on persecutory symptoms in schizophrenia-spectrum disorders, (2) impact on other related psychopathology among those experiencing psychosis and (3) relationship to functioning. Twenty-eight studies included in this review after parallel literature searches of PsycINFO and PubMed. Evidence from these studies highlighted that hostile attribution bias is elevated in schizophrenia, and that it is related to anxiety, depression and interpersonal conflict outcomes. While results suggest that hostile attributions are elevated in schizophrenia and associated with symptoms and functioning, there exist numerous persisting questions in the study of this area, including identifying which measures are most effective and determining how it presents: as a state or trait-like characteristic, via dual processes, and its situational variation.

We tried to verify whether the reformulated Learned Helplessness Model and its more fully articulated form, the Hopelessness Theory of Depression, were adequate to predict symptoms and social functioning (SF) in persons with schizophrenia-spectrum disorders by comparing a clinical group (n = 25) with a non-clinical one (n = 30). Bivariate correlations and multiple linear regressions were conducted to assess relationships between the Attribution Styles Questionnaire (ASQ), clinical variables, and SF within the clinical group. Differences between groups were found for most of attributional dimensions. A “pessimistic style” predicted depression within the clinical group. An unstable attribution bias predicted positive symptoms. General psychopathology and a global attribution style predicted 50% of the variance in general SF. The Learned Helplessness Model was suitable to predict depression regardless of psychotic symptoms and may be useful to predict clinical symptoms and SF in persons with schizophrenia spectrum disorders. Clinical and theoretical implications were discussed.

The main aim of this study was to investigate the individual contributions of neurocognitive and social‐cognitive domains to self‐reported and informant‐reported functional outcome in early psychosis. We also sought to further characterize the nature of cognitive impairments in this sample and explore the interrelationships between the social‐cognitive measures and how they correlate with measures of neurocognition and clinical symptoms. In this study, 70 patients (mean age: 24.1; 87.1% males) with primary psychotic disorder diagnosed in the previous 5 years were assessed on multiple neurocognitive (processing speed, attention, working memory, immediate verbal memory, delayed recall, visual reasoning, inhibition, planning, cognitive flexibility), and social‐cognitive domains (theory of mind (ToM), emotion recognition, attributional style, metacognitive overconfidence) as well as measures of clinical symptoms. Functional outcome was assessed with three self‐reports and two informant‐reports. On average, patients performed one or more SD below healthy controls on measures of delayed recall, ToM and metacognitive overconfidence. Emotion recognition and ToM were intercorrelated and correlated with multiple neurocognitive domains and negative symptoms. Attributional style correlated with positive symptoms. In the context of multiple variables, self‐reported functional outcomes were predicted by attributional style, whereas emotion recognition and immediate verbal memory predicted variance in informant‐reported community functioning. These results support the suggestion of a likely distinction between the predictive factors for self‐reported and informant‐reported functional outcome in early psychosis and suggest that consideration of self‐assessment of functional outcome is critical when attempting to evaluate the effects attributional style has on functional disability.

Social cognition is increasingly recognized as an important treatment target in schizophrenia; however, the dearth of well-validated measures that are suitable for use in clinical trials remains a significant limitation. The Social Cognition Psychometric Evaluation (SCOPE) study addresses this need by systematically evaluating the psychometric properties of promising measures. In this final phase of SCOPE, eight new or modified tasks were evaluated. Stable outpatients with schizophrenia (n = 218) and healthy controls (n = 154) completed the battery at baseline and 2-4 weeks later across three sites. Tasks included the Bell Lysaker Emotion Recognition Task (BLERT), Penn Emotion Recognition Task (ER-40), Reading the Mind in the Eyes Task (Eyes), The Awareness of Social Inferences Test (TASIT), Hinting Task, Mini Profile of Nonverbal Sensitivity (MiniPONS), Social Attribution Task-Multiple Choice (SAT-MC), and Intentionality Bias Task (IBT). BLERT and ER-40 modifications included response time and confidence ratings. The Eyes task was modified to include definitions of terms and TASIT to include response time. Hinting was scored with more stringent criteria. MiniPONS, SAT-MC, and IBT were new to this phase. Tasks were evaluated on (1) testretest reliability, (2) utility as a repeated measure, (3) relationship to functional outcome, (4) practicality and tolerability, (5) sensitivity to group differences, and (6) internal consistency. Hinting, BLERT, and ER-40 showed the strongest psychometric properties and are recommended for use in clinical trials. Eyes, TASIT, and IBT showed somewhat weaker psychometric properties and require further study. MiniPONS and SAT-MC showed poorer psychometric properties that suggest caution for their use in clinical trials. [ABSTRACT FROM AUTHOR]

The article deals with the basic theoretical constructs, which became the basis of modern research of social cognition in schizophrenia's violations: social percep tion, pragmatic communication, attributional style, the theory of mind and oth ers. We summed empirical data (based on these constructs) and maintained its fragmented, difficult to compile character. The tendency towards unification of the empirical data on the basis of the methodology of neurosciences, namely the social brain hypothesis were fixed. The lack of attention to the motivational com ponent in modern studies of violations of social cognition in schizophrenia is emphasized. We describe the original complex model of violations of social intel ligence, including the operational, regulatory motivational and behavioral com ponents. The data of empirical studies demonstrating the important role of moti vational component in the form of social anhedonia violations of social cognition in schizophrenia is listed.

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 FROM AUTHOR]

Introduction. Schizophrenia patients show impairments in social cognition (SC), which is a set of cognitive processes that underlie social interactions. The research about SC in schizophrenia has identified four main domains: Theory of mind (ToM), social perception, attributional style and emotional processing. The present review aims to summarize the most recent and consistent findings about SC in patients with schizophrenia, unaffected relatives and ultra-high risk for psychosis individuals (UHR), as well as its association with clinical variables and functional outcome. Methods. A systematic PsycINFO and Pubmed/Medline databases search was conducted. Results. ToM impairments have been observed in schizophrenia patients, unaffected relatives and UHR. Emotional processing disturbance has been consistently reported in schizophrenia patients and UHR. ToM and emotional processing have been correlated with symptomatology and functional outcome. However, inconsistencies have been found across studies that assess ToM and emotional processing as predictors of psychosis. Social perception and attributional style are affected in schizophrenia, but the research in at- risk populations is scarce and their relationship with symptoms or functional outcome is not clear. Conclusions. All domains of SC are impaired in schizophrenia. Non affected relatives and UHR also display deficits of SC. More research must be conducted to assess the reliability of SC domains as endophenotypes or predictors of conversion to psychosis in at-risk populations. [ABSTRACT FROM AUTHOR]

The attributional style is one domain of social cognition that involves perceiving, interpreting, and generating responses to others' intentions and behaviours in different situations. This study describes the attributional style of Egyptians with schizophrenia. The study took place in a psychiatric hospital in Egypt. Eight psychiatric wards were randomly selected, and all participants (150) with a diagnosis of schizophrenia participated. Data were collected using the Ambiguous Intention Hostility Questionnaire (AIHQ), the attributional style interview schedule, and the sociodemographic/clinical data sheet. Participants' scores on the AIHQ varied significantly between different situations (intentional, accidental, and ambiguous). The attributional style of the studied participants regarding their perceived psychosocial problems tended to be related to specific causes. These causes were mostly externally attributed to other people and to circumstances, and were perceived not to persist in the future. It would seem that Egyptians with schizophrenia tend to blame other people for negative events if these events are perceived to cause intentional harm. [ABSTRACT FROM AUTHOR]

Introduction. Although evidence suggests a discrepancy between the implicit and explicit attributional style (AS) in persons with persecutory delusions, this line of research has also produced conflicting findings. Thus, the aim of this study was to explain inconsistent results in implicit AS by introducing a modified assessment of implicit AS, which offered three attributional loci (internal, personal, and situational) instead of two (internal and external) as in previous studies and by investigating the associations between implicit AS, implicit self-esteem, explicit AS, and explicit self-esteem. Methods. Patients with acute persecutory delusions, patients with remitted persecutory delusions, and nonclinical controls were assessed in their implicit and explicit AS and implicit and explicit self-esteem. Results. Deluded patients presented an implicit “self-decreasing” AS compared to remitted patients and controls: They attributed negative events more towards themselves and positive events more towards situational factors, whereas their explicit self-serving AS was comparable to controls. Patients' implicit self-decreasing AS was associated with low implicit self-esteem. In addition, compared to remitted patients and controls, deluded patients presented low explicit and normal implicit self-esteem. Conclusions. The results shed light on the inconsistent findings in previous studies and indicate that persecutory delusions might be fed by implicit self-decreasing AS and an unstable self-esteem.

Many studies have found that people experiencing persecutory delusions have a marked tendency to use external-personal attributions when establishing the causes of negative events. Although nonclinical populations also tend to attribute negative events to external causes, those causes are typically believed to be universal in nature, rather than personal. The central goal of the present study was to investigate whether individuals with remitted persecutory delusions would display this external-personal bias regarding negative events, in comparison to remitted patients whose delusions were not paranoid in nature and to nonpsychiatric controls. Results indicate that currently paranoid patients were significantly more likely than all other groups, including the remitted paranoid group, to use external-personal attributions in negative events. Interestingly, all patient groups also were found to be significantly more likely than the controls to use internal-personal and internal-universal attributions when explaining negative events.

Abstract: Attributional style means how people typically infer the causes of emotional behaviors. No study has shown neural basis of attributional style in schizophrenia, although it was suggested as a major area of social cognition research of schizophrenia. Fifteen patients with schizophrenia and 16 healthy controls underwent functional magnetic resonance imaging while performing three (happy, angry, and neutral) conditions of attribution task. Each condition included inferring situational causes of an avatar’ (virtual character) emotional or neutral behavior. In the between-groups contrast maps of the happy conditions, the patient group compared to the control group showed decreased activations in the inferior frontal (BA 44) and the ventral premotor cortex (BA 6), in which the % signal changes were associated with negative symptoms. In the angry conditions, the patient group compared to the control group exhibited increased activations in the precuneus/posterior cingulate cortex (Pcu/PCC) (BA 7/31), in which the % signal changes were related to positive symptoms. In conclusion, patients with schizophrenia may have functional deficits in mirror neuron system when attributing positive behaviors, which may be related to a lack of inner simulation and empathy and negative symptoms. In contrast, patients may have increased activation in the Pcu/PCC related to self-representations while attributing negative behaviors, which may be related to failures in self- and source-monitoring and positive symptoms.

Abstract: People holding persecutory beliefs have been hypothesised to show a self-serving attributional style, which functions to protect self-esteem Bentall, Corcoran, Howard, Blackwood, and Kinderman (2001). Experimental support for this has been mixed. Freeman et al. (1998) suggested depressed and grandiose subgroups of those with persecutory beliefs might explain events differently. In this study, 71 participants completed measures of delusional beliefs, depression and attributional style. We hypothesised that those with persecutory beliefs would form grandiose and depressed subgroups, and that a self-serving attributional style would characterise only the grandiose subgroup. Hypotheses were partially confirmed. Clear subgroups were evident and only those with both persecutory and grandiose beliefs showed an externalising attributional style for negative events. Depression, irrespective of co-occurring persecutory beliefs, was related to a reduced self-serving bias and an externalising attributional style for positive events. On their own, persecutory beliefs were not related to any particular attributional style. Depressed and grandiose subgroups of those with persecutory beliefs might account for some of the inconsistencies in the attribution literature. Even within a single symptom group, care should be taken in both research and therapy to consider individual symptom patterns. [Copyright &y& Elsevier]

While the attributions of people with schizophrenia have been hypothesized to play a role in determining social behavior, contradictory predictions can be made about exactly what type of attributions contribute to social dysfunction. One possibility is that attributing undesirable events to internal, stable, and global factors might lead to poorer social function. An alternate possibility is that attributing events in general to internal, stable, and global factors might lead to better social function. As a test of these hypotheses, 40 participants in a post-acute phase of schizophrenia were administered the Attributional Style Questionnaire, the Positive and Negative Syndrome Scale, and the Quality of Life Scale. Stepwise multiple regressions controlling for age and education indicated that a lack of negative symptoms and the tendency to make stable attributions for life events in general predicted more frequent social contacts, a higher quality of social interaction, and better community participation on the Quality of Life Scale. Results suggest that the tendency to see life events as the result of unstable or unpredictable causes is associated with social dysfunction independent of symptom level. [ABSTRACT FROM AUTHOR]

The attributional style of outpatients with schizophrenia with and without persecutory delusions was investigated. Thirty individuals with schizophrenia were divided into persecutory-deluded and non-persecutory-deluded groups based on a score of 5 or higher on the suspiciousness item from the Expanded Brief Psychiatric Rating Scale (BPRS-E). The two resulting groups, and a nonclinical control group, were administered a battery of attributional measures, and their attributional responses were coded by both the subjects themselves and a pair of independent raters. The results showed evidence of a self-serving bias for subjects with persecutory delusions; however, this bias was not unique to those with persecutory delusions, and it disappeared when independent raters evaluated subjects' causal statements on a reliable measure of attributional style. Subjects with persecutory delusions tended to show a stronger bias toward blaming others rather than situations for negative outcomes, and there was a linear association between persecutory ideation and a self-serving attributional style. Finally, there were significant discrepancies between the attributional ratings of the persecutory-deluded subjects and those of independent judges. Implications for future research are discussed.
