Abstract

Blunted positive affect is characteristic of depression. Altered positive affect regulation may contribute to this blunting, and two regulation strategies, dampening positive affect and positive rumination, have been implicated in depression. However, the conditions under which these strategies impart risk/protective effects prior to onset of depression are unknown. The current study examined 81 healthy children (age 7-10) at low and high risk for depression on the basis of maternal history of depression and tested how dampening and positive rumination interacted with the experience of recent positive life events to predict depressive symptoms. Children at high and low risk did not differ in their use of dampening or positive rumination. However, elevated use of dampening in the context of many positive life events predicted current depressive symptoms, and specifically anhedonic symptoms, in children at low-risk for depression. These findings held when controlling for negative rumination and negative life events. Positive rumination did not interact with positive life events but was associated with higher depressive symptoms in high-risk children.

RESULTS indicate that prior to the onset of depression, positive life events may impart risk when dampening positive affect is utilized in this context, while positive rumination may increase risk for depressive symptoms.
