The Ability to Control One's Thoughts Alleviates the Adverse Effects of Negative Life Events on Depression

Although negative life events are a risk factor for developing depression, cognitive control can help maintain one's mental health. However, whether thought-control ability (TCA) can alleviate the adverse effects of negative life events on depression is unclear. Therefore, two studies were conducted to test if it does, by having participant's complete measures of negative life events, TCA, and depression. Study 1, which included 140 healthy young adults, showed TCA mediated the relationship between negative life events and depressive symptoms, and that TCA also moderated the relationship between negative life events and depressive symptoms. Study 2 recruited patients with major depressive disorder (MDD) to test whether the findings could be generalized to individuals with MDD. Study 2 found TCA also mediated the relationship between negative life events and symptoms of MDD. Suggesting that improving the ability to control negative thoughts in daily life help maintain mental health and prevent depressive symptoms.
