The Moderating Role of Locus of Control on the Relationship Between Anger Rumination and Depression in Patients with Major Depression Disorder

The moderating role of locus of control on the relationship between anger rumination and depression was investigated in a sample of patients with major depression disorder (MDD). 127 MDD patients (81 men, 45 women) were recruited to the study. Participants completed the Beck Depression Inventory, Anger Rumination Scale, and Rotter's Locus of Control Scale. Results showed that anger rumination and locus of control have direct significant relationship with depression. Internal locus of control and depression had a significant reverse relationship. Regression analysis showed that increasing levels of internal locus of control was accompanied with weaker relationship between anger rumination and depression.
