Objective People with schizophrenia show impairment in social cognition, such as emotion recognition and theory of mind. The current study aims to compare the ability of clinically stable schizophrenia patients to decode the positive, negative and neutral affective mental state of others with educational match-paired normal control.Methods 50 people with schizophrenia and 50 matched controls were compared on the positive, negative and neutral emotional valence of affective theory of mind using the Reading the Mind in the Eyes Tests.Results The results showed that people with schizophrenia performed worse in negative and neutral emotional valence than normal controls; however, no significant differences in decoding positive valence were found.Conclusion Our data suggest that there is variability in the performance of affective theory of mind according to emotion valence; the impairments seem to be specific to only negative and neutral emotions, but not positive ones.

“…The Scale for the Assessment of Positive Symptoms (SAPS) were administered to the patients to assess the severity of their positive symptoms. The total SAPS scores were between 0 and 150, with higher scores indicating greater symptom severity (Andreasen, 1984b;Charernboon, 2019a).…”

Despite the increasing emphasis on negative symptoms and social cognition impairments in patients with schizophrenia, the nature of the relationship between subdomains of negative symptoms and social cognition remain unclear. Therefore, the aim of the study was to examine the relationship between subdomains of negative symptoms, i.e. diminished expression (DE) and avolition-apathy (AA), and emotion recognition, theory of mind and neurocognition in clinically stable schizophrenia. Sixtytwo ( 62) clinically stable patients with schizophrenia were included in this study. Emotion recognition and theory of mind were assessed with the Faces test and Reading the Mind in the Eyes test (the Eyes test). Neurocognition was measured with the Addenbrooke's Cognitive Examination III. Negative symptoms were assessed with the Scale for the Thammanard Charernboon ABOUT THE AUTHOR Dr Thammanard Charernboon is a board-certified psychiatrist in Psychiatry and Geriatric Psychiatry and obtained an MSc in Advanced Care in Dementia from King's College, London, and a PhD in Clinical Epidemiology from Thammasat University.

“…Positive symptoms were measured using the Scale for the Assessment of Positive Symptoms (SAPS). 13 , 14 Positive symptoms were presented as a single unitary construct using the sum of global ratings. The global ratings range from 0 to 20 with the higher score indicating more severe positive symptoms.…”

Background: Schizophrenia has a broad range of interrelated symptoms and impairment in functioning. The objective of the study was to explore the interplay between positive symptoms, negative symptoms, neurocognition, social cognition and real-life functioning in patients with schizophrenia using network analysis. Methods: Participants were 64 clinically stable patients with schizophrenia. Psychopathologic, neurocognition, social cognition, and functioning were measured using the Scale for the Assessment of Positive Symptoms, Scale for the Assessment of Negative Symptoms, Addenbrooke’s Cognitive Examination III, Faces test, Reading the Mind in the Eyes test, and Personal Social Performance scale. Results: The network analysis suggested that functioning was the most central in the network followed by avolition and asociality. Functioning was directly connected to avolition, asociality, blunted affect, neurocognition and emotion recognition. The positive symptoms were the most remote and therefore the least important node. Conclusion: The high centrality of functioning suggests the need for improving of everyday life skills for patients with schizophrenia. Moreover, treatment of specific negative symptoms, neurocognition and emotion recognition could also enhance functional outcome.
