The impact of anger and age on depression

This study investigates the endogenous factors of trait anger and reactive factors of life events in depression, and examines how anger expression and age influences the mechanism of depression.

Eighty-nine healthy subjects were randomly selected as the reference group, and 115 outpatients with depression formed the control group. Participants completed the Life Events Scale (Selye 1969), the STAXI-2 scale, and the Beck Depression Inventory (BDI).

The analysis revealed that trait anger significantly mediates the relationship between life events and depression in the control group, with a total effect confidence interval of 0.46 (95% CI 0.11, 0.81) and an indirect effect of 0.12, accounting for 26.09% of the relative mediating effect (95% CI 0.04, 0.29).

Trait anger has a significant complete mediating effect on depression with life events as mediators in the control group. Furthermore, anger expression and age significantly moderate the mediating effects of life events on depression.
