Prediction of social adequacy based on positive and negative symptoms according to the mediating role of executive functions in patients with schizophrenia

Abstract

The aim of the study was to predict social adequacy based on positive and negative symptoms with the mediating role of executive functions in patients with schizophrenic. The population included all schizophrenic patients in Isfahan who were hospitalized in Modares and Farabi hospitals and were not in the acute stage of the disease at the time of the research. 129 people, i.e. 66 women and 63 men, were selected based on the criteria for entering the study by purposive sampling. Felner's Social Adequacy Questionnaire (1990), Nejati Executive Workers Questionnaire (2013), and Andreessen's Positive and Negative Symptoms Scale (1984) were used. The resulting data were analyzed at two descriptive and inferential levels. Hypotheses were tested using structural equations and path analysis. The results showed that the prediction model of social adequacy based on positive and negative symptoms of schizophrenia with the mediating role of executive functions has a favorable fit and executive functions can play a mediating role in the relationship between variables of negative symptoms and social adequacy (P<0.05). The results of path analysis showed that there is a negative and significant impression between negative symptoms and social competence (P<0.01) a positive and significant impression between negative symptoms and executive functions (P<0.01) between executive functions and social competence of patients, a negative and significant impression with schizophrenia (P<0.05).
