This study investigates peripersonal space (PPS) modulation in patients with anorexia nervosa (AN) versus healthy controls (HCs) and explores associations between PPS, eating-related, and general psychopathology.
Forty-six patients and 42 HCs completed a computer-based task observing videos of an approaching actor (male or female) displaying different facial expressions along with a non-social condition. Then, participants completed self-report questionnaires assessing eating-related and general psychopathology.
Mixed-models revealed that both groups adjusted PPS based on task conditions, with a gender effect favoring closer proximity to female actor. HCs reduced PPS amplitude progressively during the task, while patients did not show this effect. In patients, wider PPS correlated with lower self-esteem and facial expression identification accuracy, while in HCs, PPS was associated to body dissatisfaction and anxiety symptoms.
These findings enhance understanding of bodily self-consciousness, suggesting PPS consideration in therapeutic interactions with patients with AN and as a potential target in treatments addressing social impairment.
本研究调查神经性厌食症（AN）患者与健康对照者（HCs）的个人空间（PPS）调节情况，并探讨PPS、饮食相关及一般精神病理学之间的关联。
46例患者和42例健康对照者完成了一项基于计算机的任务，观察接近的演员（男性或女性）展示不同面部表情的视频以及一种非社交情境。然后，参与者完成了评估饮食相关和一般精神病理学的自我报告问卷。
混合模型显示，两组均根据任务条件调整PPS，存在性别效应，倾向于更靠近女性演员。健康对照者在任务期间逐渐降低PPS幅度，而患者未表现出这种效应。在患者中，较宽的PPS与较低的自尊和面部表情识别准确性相关，而在健康对照者中，PPS与身体不满和焦虑症状相关。
这些发现增进了对身体自我意识的理解，表明在与神经性厌食症患者的治疗互动中应考虑PPS，并将其作为解决社交障碍治疗的潜在靶点。
