Given that previous studies have suggested that negative interpretation bias to ambiguous stimuli sustains rumination, the present study investigates whether trait rumination is associated with negative interpretation bias. One hundred participants silently read about and envisioned six scenarios likely to induce ruminative thoughts and negative interpretations. Two indexes were employed; participants both wrote free interpretations of the scenarios and provided estimates of the probabilities of generating pre-defined interpretations. The result indicated that brooding, which is a maladaptive factor of rumination, was positively correlated with negative interpretation bias, even after controlling for depression. However, no correlations were observed between reflection, which is an adaptive factor of rumination, and interpretation bias. These results suggest that brooding can be characterized by a tendency to negatively interpret ambiguous scenarios that induce reflections of past events.
