47. Predictors of Outcome: How Individual Difference Factors Impact the Quality of Life among Adults with Schizophrenia

Schizophrenia is one of the most debilitating mental disorders that is quintessentially associated with poor quality of life (QoL). However, this is not always the case, suggesting other influences. Some factors have been identified to influence QoL outcomes in individuals with schizophrenia, such as temperament and living circumstances. However, the literature on how sociodemographic, social, and cognitive factors interact to influence QoL in individuals with schizophrenia is scarce. The purpose of this study was to examine how psychological, environmental, and personality factors predict the quality of life and well-being of outpatients with schizophrenia. Patients with schizophrenia (n = 105) were recruited from the Cleghorn Clinic and Schizophrenia Outpatient Clinic at St. Joseph’s Hospital, West 5th campus. Participants completed a battery of self-report questionnaires assessing a variety of factors and outcomes such as temperament, schizotypal personality traits, empathy, metacognition, social support, happiness, disability, and quality of life. Preliminary correlational analyses revealed that sociability (r = .3, p < 0.05), perspective taking (r = 0.6, p<0.05), empathetic concern (0.5, p<0.05), and cognitive insight (r = .51, p <0.05) were positively associated with outcomes of well-being, while shyness and social fears were negatively related to outcomes of well-being (r = -.40, p < 0.05; r = -.3, p < 0.05 respectively). Structural equation modeling will be conducted to determine predictors of outcome. The results of this study may inform how individual difference factors may impact the QoL of individuals with schizophrenia. Knowledge about how the factors interact with each other to influence QoL will be instrumental in designing novel psychosocial interventions. For example, if individuals who endorsed both high shyness and poor metacognition reported the lowest quality of life, then interventions can be designed to include training modules such as social and cognitive skills training for such factors.
