Social Etiology of Psychotic and Mood Disorders

The aim of this study was to evaluate the role of social factors on the incidence and prevalence of psychotic and mood disorders and prediction of them based on the social factors. This study was conducted based on a survey method and on the 150 hospitalized patients with psychotic and mood disorders admitted in the Yazd Centre of Psychiatry between March 2004 and March 2005. Random sampling method was used for patients selection. Distribution of psychotic and mood disorders in these patients were then compared according to some community variables such as gender, social class, marital status, geographical locality of accommodation, family history, and age. There were significant differences between the three variables of social class (p<0.05), marital status (p<0.05), and family history (p<0.01), and the type of disorder. Results of logistic regression analysis showed that out of all considered variables in the model, two variables of social class and family history could predict the type of mental disorder. A correlation exists between the socio-economical status of the patients with the distribution of psychotic and mood disorders.
