Abstract

Rumination has been considered as a cardinal cognitive process of depression which roles as a risk factor for the onset, maintenance and recurrence of depressive symptoms. Ruminative Response Scale(RRS) is the most widely known measurement of ruminative responses. RRS has shown good reliability and validity in various studies, though factor structure of RRS has been inconsistent throughout precedent studies. In the present study, K-RRS was administered to 991 clinically depressive patients(678 with major depressive disorder, 227 with depressive disorder not otherwise specified, and 86 with dysthymic disorder). Four competitive models which were drawn from precedent studies were adopted to find the best model of K-RRS for depressive patients. We found that Kim et al.(2010)’s 3 factor model based on exploratory factor analysis of 360 korean undergraduates was the best fitting model for the korean depressive sample. We found that K-RRS is best explained by the hierarchical 3 factor model which holds rumination as a superior factor, and reflection, self-reproach and depressive rumination as primary factors.
