Abstract

Two studies examined the relationships among trait negative affectivity, dispositional thought suppression, and intrusions in non-clinical samples. In Study 1 (N=87), participants were presented with a series of emotionally evocative images and intrusions were examined 48 h after presentation via self-report. In Study 2 (N=118), intrusions were examined using a behavioral Key-press and self-report at two time points (5 and 20 min) following exposure to a series of emotionally evocative images. In each study, participants were assessed for trait negative affectivity and the tendency to engage in thought suppression in response to unpleasant cognitions. Results from both studies support a model in which chronic thought suppression fully mediates the relationship between negative affectivity and the frequency of intrusions.
