本研究考虑了不同程度的疼痛灾难化的青少年的注意功能。具体来说，我们研究了疼痛灾难化和注意力偏见疼痛面部表情之间的关系。此外，在疼痛的背景下，利用双过程模型，我们研究了注意控制对这种关系的调节作用。青少年（N = 73;年龄，16-18岁）进行了点探测任务，其中疼痛和中性表情的面部表情分别为100毫秒和1250毫秒。参与者还完成了自我报告的疼痛灾难化和注意力控制措施。我们发现，虽然疼痛灾难化对疼痛面孔的注意偏向没有主要影响，但注意力控制确实显着缓和了这种关系。进一步的分析显示，只有在高度灾难化的青少年中，注意力控制水平较低与对疼痛面孔的注意力警惕性增加显著相关。此外，我们发现，较差的注意力控制与疼痛面孔的注意力偏差增加有关（无论疼痛灾难化水平如何），当这些面孔呈现相对较长的持续时间（即1250毫秒）时，而不是短时间（即100毫秒）。本研究支持疼痛中注意过程的双重过程模型，从而复制了以前在精神病理学文献中的发现，但将其扩展到疼痛的研究。我们的研究结果的理论和临床意义进行了讨论。
This study considered the attentional functioning of adolescents with varying levels of pain catastrophizing. Specifically, we investigated the relationship between pain catastrophizing and attention bias to pain facial expressions. Furthermore, drawing on dual process models in the context of pain, we investigated the moderating role of attention control on this relationship. Adolescents (N = 73; age, 16-18 years) performed a dot-probe task in which facial expressions of pain and neutral expressions were presented for 100 milliseconds and 1250 milliseconds. Participants also completed self-report pain catastrophizing and attention control measures. We found that although there was no main effect of pain catastrophizing on attention bias towards pain faces, attention control did significantly moderate this relationship. Further analysis revealed that lower levels of attention control were significantly associated with increasing attentional vigilance towards pain faces only within high catastrophizing adolescents. In addition, we found that poorer attention control was related to increased attention bias for pain faces (regardless of pain catastrophizing level) when these faces were presented for relatively longer durations (ie, 1250 milliseconds) but not for short durations (ie, 100 milliseconds). This study supports a dual process model of attentional processes in pain, thus replicating previous findings within the psychopathology literature but extending them to the study of pain. Theoretical and clinical implications of our findings are discussed.
