Anger expression styles in schizophrenia spectrum disorders: associations with anxiety, paranoia, emotion...

Heightened levels of anger and dysregulated expression of anger have been associated with poorer outcomes and treatment response for persons with schizophrenia spectrum disorders. Less is known, however, about the psychological processes that determine the extent to which anger is expressed in a more versus less adaptive manner. To explore this issue, this study gathered reports of anger expression style in 88 persons with schizophrenia or schizoaffective disorder using the State-Trait Anger Expression Inventory, Second Edition. The authors additionally assessed anxiety, suspiciousness, emotion recognition, self-esteem, and cumulative trauma history. Correlations and multiple regression analyses showed that outward anger control, that is, the suppression of anger, was predicted by lower levels of suspiciousness, poorer emotion recognition, and reduced anxiety. Participants who endorsed greater anxiety and had experienced more traumatic events reported a heightened tendency to express anger both inwardly and outwardly.
