Description

Depression is characterized by maladaptive activation of cognitions. We compared activation of positive and negative cognitions in a community sample of 117 adolescents (age 10-14 years, 54.7% female). We hypothesized that depressed youth would have more negative cognitions after a stressor and fewer positive cognitions after a reward than nondepressed youth. Significant interactions were found for group by condition (pre-post) for negative self-affect (Wilks' Λ = .966, F(1, 114) = 3.96, p = .049) and positive world cognitions (Wilks' Λ = .961, F(1, 114) = 4.57, p = .035); depressed participants showed greater cognitive reactivity for negative self-affect following stress and for positive world cognitions following reward compared to nondepressed participants.
