Those who always suppress their anger are more likely to develop depressive symptoms. Psychologist Anett Müller-Alcazar and her colleague Reinhard Maß prove this in a study.

The newly developed scale shows that the inhibition to express aggression constructively could indicate an emotional disorder. Inhibiting aggression does not necessarily have to lead to problems - for example if a person has sufficient resources, social relationships are balanced and borders are balanced. If constructive aggression is permanently inhibited or other mental problems develop, depression could develop. The reduction of aggression could also be an important in the psychotherapy of depression and anxiety disorders.
