Abstract
Purpose: Although individual differences in temperament have been shown to influence Quality of Life (QoL) among individuals with schizophrenia, there exists considerable heterogeneity in such outcomes suggesting moderating factors. Here we used event-related potential (ERP) methodology to examine whether the processing of facial emotions moderated the association between shyness and objective QoL among adults with schizophrenia.Methods: Forty stable outpatients with schizophrenia completed measures of shyness and QoL. Early visual ERP components (P100, N170) were recorded while participants viewed emotional faces.Results: We observed a significant interaction between shyness and P100 and N170 amplitudes in response to fearful faces in predicting Intrapsychic Foundations QoL. Patients with reduced P100 and N170 amplitudes to fearful compared to neutral faces displayed the lowest QoL, but only if they were also high in shyness. We also found a significant interaction between shyness and ERP latency at the P100 and N170 in response to happy faces. Patients who displayed longer P100 and N170 latencies to happy faces compared to neutral faces and with higher shyness levels scored lower on Intrapsychic Foundations and Interpersonal Relations QoL, respectively.Conclusion: These findings suggest that the neural processing of emotional faces and shyness interact to predict aspects of QoL among outpatients with schizophrenia.

Abstract
PURPOSE Recently, cognitive variables such as negative and positive self-belief and thoughts have attracted much attention because they are associated with functional outcomes and quality of life (QOL). However, it is unclear how cognitive variables affect subjective and objective QOL. This study aimed to investigate the relationship of negative and positive self-belief and thoughts with subjective and objective QOL. PARTICIPANTS AND METHODS Thirty-six people with schizophrenia participated in this study. Subjective and objective QOL were assessed with the Schizophrenia Quality of Life Scale (SQLS) and Quality of Life Scale (QLS), respectively. Neurocognitive function was assessed with the Brief Assessment of Cognition in Schizophrenia (BACS). Clinical symptoms were assessed with the Positive and Negative Syndrome Scale and Calgary Depression Scale for Schizophrenia. Side effects were assessed with the Drug-induced Extrapyramidal Symptoms Scale (DIEPSS). Negative and positive self-belief and thoughts were assessed with the Defeatist Performance Belief Scale and Automatic Thoughts Questionnaire-Revised. A generalized linear model was tested, with subjective and objective QOL as the response variable and symptoms, neurocognitive function, and cognitive variables that were significantly correlated with subjective and objective QOL as explanatory variables. RESULTS In the schizophrenia group, the common objects score on the QLS was predicted by the composite BACS score, and the total QLS score was predicted by the DIEPSS score. Motivation and Energy, Psychosocial, and Symptoms and Side effects scores on the SQLS were predicted by depression and by negative automatic thought (NAT) and positive automatic thought (PAT). CONCLUSION Our results indicated that key targets for improving objective and subjective QOL in people with schizophrenia are side effects, neurocognitive function, depression, and NAT and PAT.
