The degree to which someone, when they are dysphoric (feeling down), focuses attention on their symptoms and their potential causes, implications and consequences is referred to as mood-related ruminative response style (MRRS). It has been suggested that MRRS can make people more vulnerable to depression as they inappropriately use negative thoughts and memories to understand current circumstances, ruminate about their dysphoria instead of using problem-solving skills or adaptation and talk about their thoughts all the time alienating potential sources of social support. A U.K. study of 26 depressed adolescents compared the effects of using psychosocial interventions and SSRIs (antidepressants) to that of using the samet treatment but with CBT on top. The adolescents in the CBT group showed significantly greater reductions in ruminations compared to the control group and rumination was reduced to the levels of never-depressed controls in those who had recovered from depression and received CBT. However, there were no significant differences in the reduction in self-reported depressive symptoms between the two groups.
