Previous research has linked anger suppression with depression. This study extended prior research by comparing people who had recovered from a major depression (RD) with those who had never been depressed (ND). The RD group significantly exceeded the ND group in the degree to which they reported holding anger in and being afraid to express it. Also, RD participants were more likely to endorse attitudes consistent with silencing the self theory, believing they must hide their feelings to preserve relationships. They were also more likely to have experienced an anger attack. Both silencing the self and a history of anger attacks were significantly correlated with fear of anger expression; future longitudinal or experimental studies are needed to determine whether these variables play a causal role in anger inhibition and in recurrence of depression.
