OBJECTIVE
To investigate whether individuals with chronic fatigue syndrome (CFS) show an attentional bias towards health-threat information.
METHODS
Attentional bias (AB) was assessed in individuals with CFS and healthy controls using a visual probe task which presented health-threat and neutral words and pictures for 500 ms. Self-report questionnaires were used to assess CFS symptoms, depression, anxiety, and social desirability.
RESULTS
Compared to a healthy control group, the CFS group showed an enhanced AB towards heath-threat stimuli relative to neutral stimuli. The AB was not influenced by the type of stimulus (pictures vs. words).
CONCLUSION
The finding of an AB towards health-threat information in individuals with CFS is supportive of models of CFS which underlie cognitive behavior therapy.
目的
研究慢性疲劳综合征（CFS）患者是否对健康威胁信息存在注意偏向。
方法
使用视觉探测任务对CFS患者和健康对照者的注意偏向（AB）进行评估，该任务呈现健康威胁和中性的文字及图片，持续500毫秒。采用自我报告问卷评估CFS症状、抑郁、焦虑和社会期望性。
结果
与健康对照组相比，CFS组相对于中性刺激对健康威胁刺激表现出更强的注意偏向。注意偏向不受刺激类型（图片与文字）的影响。
结论
CFS患者对健康威胁信息存在注意偏向这一发现支持了认知行为疗法所依据的CFS模型。
