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.
两项研究考察了非临床样本中特质消极情感、 dispositional思想抑制和侵入之间的关系。在研究1（N = 87）中，向参与者呈现一系列唤起情绪的图像，并在呈现后48小时通过自我报告检查侵入情况。在研究2（N = 118）中，在接触一系列唤起情绪的图像后的两个时间点（5分钟和20分钟），使用行为按键和自我报告来检查侵入情况。在每项研究中，评估参与者的特质消极情感以及因不愉快认知而进行思想抑制的倾向。两项研究的结果都支持这样一个模型，即长期的思想抑制完全中介了消极情感与侵入频率之间的关系。
