This study investigated the time course of attention to pain and examined the moderating effect of attentional control in the relationship between pain catastrophizing and attentional bias in chronic pain patients.
A total of 28 patients with chronic pain and 29 pain-free individuals observed pictures of pain, happy and neutral facial expressions while their gaze behaviour was recorded. Pain intensity and duration, anxiety, depression, stress, attentional control and pain catastrophizing were assessed by questionnaires.
In all subjects, the pattern of attention for pain faces was characterized by initial vigilance, followed by avoidance. No significant difference was found between the two groups in terms of orientation towards the stimuli, the duration of first fixation, the average duration of fixation or number of fixations on the pain stimuli. Attentional control moderated the relationship between catastrophizing and overall dwell time for happy faces in pain patients, indicating that those with high attentional control and high catastrophizing focused more on happy faces, whereas the reverse was true for those with low attentional control.
This study supported the vigilance-avoidance pattern of attention to painful facial expressions and a moderation effect of attentional control in the association between pain catastrophizing and attentional bias to happy faces among pain patients.
本研究调查了对疼痛的注意时间进程，并检验了注意控制在慢性疼痛患者的疼痛灾难化与注意偏向之间关系中的调节作用。
共有28名慢性疼痛患者和29名无疼痛个体在观看疼痛、快乐和中性面部表情图片时，其注视行为被记录下来。通过问卷评估疼痛强度和持续时间、焦虑、抑郁、压力、注意控制和疼痛灾难化。
在所有受试者中，对疼痛面孔的注意模式以最初的警觉随后是回避为特征。两组在对刺激的定向、首次注视持续时间、平均注视持续时间或对疼痛刺激的注视次数方面未发现显著差异。注意控制调节了疼痛患者中灾难化与对快乐面孔的总体停留时间之间的关系，表明注意控制高且灾难化程度高的患者更多地关注快乐面孔，而注意控制低的患者则相反。
本研究支持了对痛苦面部表情的警觉-回避注意模式，以及注意控制在疼痛患者的疼痛灾难化与对快乐面孔的注意偏向之间关联中的调节作用。
