Rumination is a maladaptive emotion regulation strategy in which a person repetitively focuses on their emotions and the reason for these emotions. Rumination can be maladaptive for everyone regardless of having a mental illness. Research has found that rumination is linked to higher intensities of depressive symptoms. Major depression disorder patients report more rumination than non-depression individuals. It was also found that major depression disorder patients are also more negatively affected by rumination when it was experimentally induced than undepressed individuals.
