This study examined whether symptoms of GAD and depression were differentially associated with predictions individuals made about their future. Sixty-five undergraduates completed the BDI-II and GAD-Q-IV, predicted whether positive and negative events would happen to them in the future, and indicated their level of certainty about these predictions. Both higher GAD and depression symptoms were associated with an increased tendency to anticipate that negative events would happen. However, only depression was associated with the tendency to predict that positive events would not occur, even after adjusting for GAD symptoms. In addition, GAD and depression scores were positively associated with pessimistic certainty about negative events, but only depression was associated with increased certainty about both the occurrence of negative outcomes and a lack of positive outcomes, even after adjusting for GAD symptoms.
