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

The moderating role of locus of control on the relationship between anger 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, Multidimensional Anger Inventory, and Rotter's Locus of Control Scale. Results showed that anger dimensions and locus of control have direct significant relationship with depression levels. Internal locus of control and depression had a significant reverse relationship. Regression analysis revealed that increasing levels of internal locus of control was accompanied with weaker relationship between anger-eliciting situations and depression.
