Abstract
Functional impairment is a common symptom in schizophrenia (SZ) and bipolar disorder (BD). Pharmacological treatments have limited functional recovery in both disorders. Social cognition, a cognitive process, has been associated with functioning in mental disorders. Theory of mind (ToM) is considered a key factor in understanding the social cognitive deficits in SZ and BD. Our study aimed to investigate the relationship between ToM and functioning in SZ, BD, and healthy controls (HC) and compare ToM and functioning impairments between groups. A total of 208 participants (HC n = 69; BD n = 89; SZ n = 50) were evaluated with the Functioning Assessment Short Test (FAST), Reading the Mind in the Eyes Test (RMET), the Vocabulary subtest of the Wechsler Abbreviated Scale for Intelligence (WASI) and the Hopkins Verbal Learning Test - Revised (HVLT-R). Comparisons of RMET between low- and high-functioning individuals and multiple linear regression analyses were conducted for each group. Multiple regression analysis revealed that the association between ToM and psychosocial functioning was observed only in SZ (β = -1.352, p = 0.008). Low-functioning SZ participants showed a lower ToM performance compared to participants with high-functioning SZ (t = 1.80, p = 0.039, Cohen's d = 0.938). No significant associations were found in the other groups. ToM is essential to understand the functional impairment in SZ, more than in BD. Furthermore, ToM may be a primary target for intervention strategies in improving functioning in SZ.

Schizophr Res 2023; 259:150-157.

Abstract
BACKGROUND People with schizophrenia (SZ) often present with theory of mind (ToM) deficits and with speech production deficits. While a link has been established between ToM abilities and symptoms of thought disorder, much less is known about other aspects of speech production in SZ. STUDY DESIGN This is a case-control study in which 25 stable outpatients with recent-onset SZ (27.1 years, 22 men) and 22 matched healthy controls (25.6 years, 16 men) performed a collaborative, verbal production task with a real interaction partner. Blind raters scored how easy participants made it to understand them (Facility ratings), how interesting they were to listen to (Interest ratings) and how expressive they were (Expressivity ratings). ToM was assessed with the Combined Stories Test and Sarfati's cartoon task. Symptoms were assessed with the PANSS five-factor version. STUDY RESULTS Compared to healthy controls, SZ received significantly lower ratings for all three aspects of their verbal productions (Facility, Interest and Expressivity), despite the raters being blind to group membership. Interestingly, the Facility ratings were linked to ToM performance in the SZ group, which suggest that SZ participants who have difficulties understanding others (ToM deficits) also make it harder for others to understand them. Other notable findings include a strong link between the Expressivity ratings and the Interest ratings for both groups, and significant correlations between the Facility ratings and Cognitive/Disorganisation symptoms, and between the Expressivity ratings and both Negative and Depression/Anxiety symptoms in SZ. CONCLUSION Studying speech production during real, collaborative social interactions could help move beyond the individual approach to SZ deficits, making it possible to involve the interaction partners to promote more efficient communication for people with schizophrenia.

Abstract
BACKGROUND Cognitive impairment persists through the course of schizophrenia and affects patients' activities of daily living. AIM This study aims to investigate the effects of a virtual reality (VR) serious game training program on the cognitive function of people diagnosed with schizophrenia. MATERIALS AND METHODS Sixty-four eligible people diagnosed with schizophrenia were recruited and randomly assigned to the intervention group (n = 31) and the control group (n = 33). The control group received standard psychiatric care. The intervention group was trained with an additional VR game twice a day for at least 10 days during hospitalization. Cognitive function was measured at enrollment and before discharge using the Brief Cognitive Assessment Tool for Schizophrenia. RESULTS Compared with those of the control group, the results of the working memory (t = 3.463, Cohen's d = 0.87, p = 0.001) and executive function (TMTA: Z = -2.272, Cohen's d = 0.59, p = 0.023; TMTB:Z = -2.365, Cohen's d = 0.62, p = 0.018) of the intervention group after intervention were significantly better. However, there was no significant difference in the results of social cognition (Z = -1.394, Cohen's d = 0.35, p = 0.163) between the two groups. CONCLUSION Intensive active virtual reality serious game training in addition to standard psychiatric care can significantly improve working memory and executive function in people diagnosed with schizophrenia. IMPLICATIONS FOR PRACTICE When helping improve the cognitive function of people diagnosed with schizophrenia, mental health professionals should identify cognitive domains to be enhanced and develop corresponding serious game training strategies.

Abstract
Schizophrenia is associated with major functioning difficulties. Theory of mind (ToM), the ability to infer the mental states of others, is an important determinant of functioning. However, the contribution of ToM to each specific domain of functioning remains to be better understood. The objectives of this meta-analysis were to document and compare the magnitude of the associations between ToM and (1) different domains of functioning (social functioning, productive activities, and instrumental activities of daily living), each assessed separately for functional performance and functional outcome and (2) different aspects of functioning (functional performance and functional outcome) in schizophrenia. Fifty-nine studies (N = 4369) published between 1980 and May 2019 targeting patients with schizophrenia or schizoaffective disorder aged between 18 and 65 years old were included. Studies were retrieved from seven databases. Correlations were extracted from the articles, transformed into effect sizes Zr and combined as weighted and unweighted means. The strength of the associations between the domains and aspects of functioning were compared using focused tests. A moderate association was observed between ToM and all domains of functioning, with a stronger association between ToM and productive activities compared with social functioning (only for functional outcome [χ2(2) = 6.43, P = 0.040]). Regarding the different aspects of functioning, a stronger association was observed between ToM and functional performance, compared with functional outcome, for overall functioning (χ2(1) = 13.77, P < 0.001) and social functioning (χ2(1) = 18.21, P < 0.001). The results highlight a stronger association of ToM with productive activities and with functional performance, which should be considered in future studies to improve functional recovery in schizophrenia.

Abstract
OBJECTIVE Longitudinal research supports an effect of participation in aspects of community life (e.g., leisure activity, employment) on neurocognition in the general population. This study examined the extent and nature of the relationship between community participation and neurocognition among people with serious mental illnesses. METHOD Participants included 168 adults with schizophrenia spectrum or affective disorder diagnoses who completed the Temple University Community Participation Measure and Brief Assessment of Cognition in Schizophrenia. Hierarchical multiple regression analyses explored linear and curvilinear effects of the amount and breadth of community participation on neurocognition. RESULTS Significant linear relationships existed between amount of community participation and overall neurocognitive functioning, motor speed, verbal fluency, and attention/processing speed, and between breadth of participation and verbal fluency. Significant curvilinear effects were noted between amount of community participation and verbal memory, and between breadth of community participation and overall neurocognitive functioning and motor speed. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Findings suggest that enhanced community participation may contribute to improved neurocognitive functioning, further supporting the importance of this rehabilitation target.

Abstract
Neurocognitive and social cognitive deficits are a hallmark of schizophrenia. The purpose of the present study was to investigate long-term changes in theory of mind (ToM), executive functions, lexical retrieval, and speed of information processing/attention in schizophrenia. We followed-up 31 outpatients with schizophrenia and 31 healthy control subjects for 15 years. ToM was assessed with the Reading the Mind from the Eyes Test (RMET), whereas neurocognitive functions were measured with the verbal fluency (VF) task (executive functions and lexical retrieval) and with the Digit-Symbol Substitution Test (DSST) (speed of information processing/attention). Clinical symptoms and general functioning were rated with the Positive and Negative Syndrome Scale (PANSS) and with the Global Assessment of Functioning (GAF) scale, respectively. At baseline assessment, patients with schizophrenia exhibited significant and generalized impairments on all measures. At follow-up, relative to the baseline, we observed marked improvements in ToM (RMET), stability in executive functions and lexical retrieval (VF), and a significant decline in psychomotor speed/attention (DSST) in schizophrenia. Clinical symptoms and psychosocial functions did not differ at baseline and at follow-up examinations (mild-to-moderate symptoms on the PANSS and moderate difficulty in social and occupational functions on the GAF). These results indicate that patients with schizophrenia with mild-to-moderate symptoms and functional deficits are characterized by improved ToM during over a decade.

Abstract
Research suggests that theory of mind (ToM) deficits are related to chronic psychosis and to first-episode psychosis (FEP) independently of other neurocognition domains. The aim of this study was to measure the differences in ToM area in a Spanish population of FEP sample (N = 32) and in a healthy control group (N = 32). A further aim was to describe the relationship between different domains of neurocognition, psychotic symptoms and social functioning with ToM in this sample. ToM was assessed with the MASC task. Estimated IQ with a short version of the WAIS III, Rey-Osterrieth Complex figure, Trail Making Test, Stroop test and Wisconsin Carting Sorting test were used to assess neurocognition. Psychotic symptoms were assessed with Community Assessment of Psychic Experiences (CAPE) in both groups and with PANSS scale in FEP group. GAF and Cannon-Spoor scales were used to measure social functioning before and after onset of psychosis. FEP showed important deficits in ToM domain compared to controls. A worse executive functioning was associated with worse scores in ToM task. However, no relation was found between positive or negative psychotic symptoms and ToM or social functioning and ToM. In our sample neurocognition tests were strongly related to ToM domain independently of other variables.

Abstract
The deficit in ability to attribute mental states such as thoughts, beliefs, and intentions of another person is a key component in the functional impairment of social cognition in schizophrenia. In the current study, we compared the ability of persons with first episode schizophrenia (FE-SZ) and individuals with schizophrenia displaying symptomatic remission (SZ-CR) to decode the mental state of others with healthy individuals and schizoaffective patients. In addition, we analyzed the effect of dopamine-related genes polymorphism on the ability to decode the mental state of another, and searched for different genetic signatures. Our results show that overall, individuals with schizophrenia performed worse in the "Reading the Mind in the Eyes" (eyes) test, a simple well-defined task to infer the mental state of others than healthy individuals. Within the schizophrenia group, schizoaffective scored significantly higher than FE-SZ, SZ-CR, and healthy individuals. No difference was observed in performance between FE-SZ and SZ-CR subjects. Interestingly, FE-SZ and SZ-CR, but not schizoaffective individuals, performed worse in decoding negative and neutral emotional valance than the healthy control group. At the genetic level, we observed a significant effect of the DAT genotype, but not D4R genotype, on the eyes test performance. Our data suggest that understanding the mental state of another person is a trait marker of the illness, and might serve as an intermediate phenotype in the diagnostic process of schizophrenia disorders, and raise the possibility that DA-related DAT gene might have a role in decoding the mental state of another person.

Abstract
While a wealth of studies have evaluated cross-sectional links between cognition and functioning in schizophrenia, few have investigated the relationship between change in cognition and change in functioning in the context of treatment trials targeted at cognition. Identifying cognitive skills that, when improved, predict improvement in functioning will guide the development of more targeted rehabilitation for this population. The present study identifies the relationship between change in specific cognitive skills and change in functional ability during one year of cognitive rehabilitation. Ninety-six individuals with schizophrenia were assessed with a battery of cognitive measures and a measure of performance-based functioning before and after cognitive training consisting of either drill-and-practice cognitive remediation or computer skills training. Results revealed that while working and episodic memory, problem-solving, and processing speed skills all improved during the trial, only improved working memory and processing speed skills predicted improvement in functional ability. Secondary analyses revealed these relationships were driven by individuals who showed a moderate level (SD≥0.5) of cognitive improvement during the trial. These findings suggest that while a variety of cognitive skills may improve during training targeted at cognition, only improvements in a subset of cognitive functions may translate into functional gains.

Abstract
OBJECTIVE To compare the profile of attributional style of a group of out-patients with bipolar disorder (BD) and schizophrenia (SZ), and a group of healthy controls - along with other social cognition domains - such as emotion recognition and theory of mind (ToM). METHOD A total of 46 out-patients diagnosed with BD, 49 with SZ, and 50 healthy controls were assessed in attributional style (Ambiguous Intentions Hostility Questionnaire), facial emotion recognition (FEIT, FEDT, ER-40), and ToM (Hinting Task). Symptomatology, clinical variables and global functioning were also collected. RESULTS Both groups with SZ and BD showed hostile social cognitive biases, compared with the control group. Patients with BD also showed a capacity for emotional recognition similar to those with SZ and worse than control subjects. In contrast, patients with SZ showed poorer ToM. Subthreshold depressive symptoms and an attributional style toward hostility appeared as the factors with a strongest association to global functioning in BD. In SZ, PANSS score and a tendency to aggressiveness were the most relevant factors. CONCLUSION Attributional style (along with other domains of social cognition) is altered in out-patients with BD and SZ. The presence of residual symptoms and a hostile social cognitive bias may contribute to the functional impairment of both groups.
