Objective Rumination is a negative coping strategy defined as repetitive and passive focusing on negative feelings such as depression. The Ruminative Response Scale (RRS) is a widely-used instrument to measure rumination, but there is continuing argument about theconstruct validity of the RRS, because of probable overlap between the measurement of depression and that of rumination. The RRS-Revised(RRS-R), which removed 12 items of the RRS, is suggested as a more valid instrument for measuring rumination. Therefore, wetranslated RRS-R into Korean and explored the reliability, validity and factor structure in patients with major depressive disorders. Methods Seventy-nine patients with major depressive disorder took the Korean version of RRS, RRS-R, State Trait Anxiety Inventory,Beck Depression Inventory and Penn State Worry Questionnaire. We performed exploratory factor analysis of RRS-R, and tested constructvalidity, internal reliability and test-retest reliability. Results The internal and test-retest reliability of RRS-R was high. Factor analysis revealed that RRS-R is composed of two factors. ‘Brooding’ factor explained 56.6% and ‘Reflection’ factor explained 12.5%. RRS-R, especially ‘Brooding factor’, was highly correlated withother clinical symptoms such as depression, anxiety and worry. ConclusionaaIn this study, we find out the RRS-R is more reliable and valid than the original RRS in Korean patients with depressionbecause the RRS-R is free from the debate about the overlap of item with BDI. We also revealed that ‘Brooding’ is highly correlated withdepressive symptoms. RRS-R may be a useful instrument to explore the implication of ‘Brooding’ in depression.
