Role of Type D Personality in Prediction of Occurrence or Non-occurrence of Premenstrual Dysphoric Disorder

Abstract

The present study aimed to investigate the role of Type D personality in the prediction of the occurrence or non-occurrence of premenstrual dysphoric disorder. To do so, among the population of high school students in Tabriz City, 60 students were selected as premenstrual dysphoric patients, and 60 students were selected as normal samples, after conducting a diagnostic interview based on DSM-V and recording symptoms in Dickerson's daily symptom recording questionnaire. Both groups were asked to answer Denollet's Personality Type Questionnaire (DS14). The data obtained were analyzed using the discriminant analysis. The results indicate that there is a significant difference between the patient group and the normal group in terms of Type D personality and its components (social inhibition and negative affectivity). The variables of Type D personality and its components can significantly predict the occurrence or non-occurrence of PMDD. According to these findings, it can be said that the mutual relationships between psychological states and the body states can be theoretically explained and the evidence in the present study also confirms such relationships.
