Attentional bias (AB) modification treatment targeting general or social anxiety has been recently highlighted as a potential novel approach for the treatment of anorexia nervosa (AN). The purpose of this study was to examine threat-related AB in patients with ANand healthy control participants (HC) and the relationship between AB and eating disorder and other psychopathology.
Forty-nine female outpatients with AN or Eating Disorder Not Otherwise Specified, Anorexia Type (EDNOS-AN), and 44 female HC completed a dot-probe task with threat words and a range of self-report measures assessing eating disorder symptoms and other psychopathology.
There was no evidence for a differential threat-related AB in AN patients despite elevated anxiety in this group. The AB-index, a parameter of the magnitude of attention allocation when two competing stimuli are presented, did not correlate with any of the self-report measures. However, patients with AN responded significantly more slowly to the probe as compared to controls, regardless of the valence or position of the stimuli.
The results suggest that the AB in AN patients may be specific to eating disorder-relevant anxieties.
针对一般或社交焦虑的注意力偏差(AB)修正治疗最近被强调为治疗厌食症(AN)的一种潜在新方法。本研究的目的是检查 AN 患者和健康对照参与者(HC)的与威胁相关的 AB,以及 AB 与饮食障碍和其他精神病理学之间的关系。
49 名女性 AN 或未特定饮食障碍、厌食型(EDNOS-AN)门诊患者和 44 名女性 HC 完成了带有威胁词汇的点探测任务,以及一系列评估饮食障碍症状和其他精神病理学的自我报告量表。
尽管该组焦虑水平升高,但 AN 患者没有表现出与威胁相关的 AB 的差异。AB 指数,即呈现两个竞争刺激时注意力分配幅度的参数,与任何自我报告量表都没有相关性。然而,与对照组相比,无论刺激的效价或位置如何,AN 患者对探针的反应明显较慢。
结果表明,AN 患者的 AB 可能特定于与饮食障碍相关的焦虑。
