Relationship between Worry, Rumination and Metacognitive Beliefs and Major Depressive Symptoms

The present study aimed to determine the relationship between metacognitive beliefs and worry and rumination. Also, this study aimed to predict vegetative and nonnegative (cogniting) symptoms of major depressive disorder (MDD) based on these two constructs. This study was conducted with a creational research method. 45 patients (18 male and 27 female) diagnosed with MDD were selected using convenience sampling method. The completed Pennsylvania state worry questionnaire ruminative response scale metacognitive questionnaire-30 negative and positive beliefs about rumination scale, and Beck depression inventory results of pearson correlation showed a significant correlation between positive and negative metacognitive beliefs about rumination and severity ruminative thoughts. Besides, there was a posiive significant correlation between ruminative thoughts and vegetative and non vegetative symptoms in MDD (p<.01). Furthermore, multiple regression method results showed that the combination of ruminative thoughts and being worried explained 26 percent of vegetative and non vegetative (cognitive) symptoms (p<.01). Results suggested the effect of the third level of cognition (metacognition) on the second level (style of thinking) in rumination.
