Mood as input and catastrophic worrying.

The authors describe 3 experiments investigating a "mood-as-input" approach to understanding catastrophic worrying. Experiment 1 found that induced negative mood increased the number of steps emitted in both a catastrophizing interview procedure and a positive iteration task. Experiment 2 found that the number of items that worriers emitted in an iterative item generation task was dependent on the stop rules specified by the procedure. Experiment 3 found that manipulating the stop rules for catastrophizing had differential effects on worriers and nonworriers, depending on the nature of the stop rules specified. These results suggest that mood provides information about continuing or terminating the catastrophizing process that is interpreted in the context of the stop rules for the task. It is argued that the mood-as-input hypothesis accounts for the facts of exacerbated catastrophizing in worriers better than explanations couched in terms of either mood congruency effects or worriers possessing a generalized perseverative iterative style.
