Aim: According to the Analytical Rumination Hypothesis (ARH) depressive symptoms facilitate the process of rumination, which temporarily increases the ability to analyse complex problems preceding depression and thus increases the probability of lowering depressive symptoms in time. Moreover, cognitive performance is decreased, as the mental capacity is occupied by the process of rumination. The aim is to elucidate the impact of depressive rumination on cognitive functioning in time. Methods: Clinically depressed individuals (N=79) and matched healthy controls (N=44) were assessed at baseline and after a month. Depression severity was assessed by MADRS. Self-report scales on rumination (ARQ, subscales Causal Analysis - CA and Problem Solving Analysis - PSA) and perceived level of problem complexity (PCQ) were used. Cognitive performance was assessed using Trail Making Test (TMT) and Auditory Verbal Learning Test (AVLT). Results: In patients, the severity of depressive symptoms has decreased and the dominant type of rumination has changed in time. Depressive symptoms (MADRS) positively correlated with the severity of ruminations (ARQ) and with the subjective problem complexity (PCQ), and negatively correlated with the capacity of auditory verbal memory (AVLT 1-5). Regression model showed that rumination type ratio (CA, PSA) was a predictor of the depression severity change in time. Conclusion: In patients, the severity of depression decreases in time and cognitive performance improves but remains worse compared to controls. Rumination is present in patients with depression and the type of rumination changes in time. The characteristics of prevailing rumination type predict the development of depressive symptoms.
