Abstract

Objectives

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.

Method

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.

Results

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.

Conclusion

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.

关于神经性厌食症患者和健康受试者周身空间的定量研究：社会变量的作用以及与精神病理学的关联

方法46名神经性厌食症患者和42名健康对照者完成了一项基于计算机的任务，在非社交条件下观察一名靠近的演员（男性或女性）展示不同面部表情的视频。结果混合模型显示，两组患者都根据任务条件调整了PPS，性别效应更倾向于靠近女性演员。高危人群在任务过程中会逐渐减小 PPS 振幅，而患者则不会出现这种效应。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 HCs 中，PPS 与身体不满意和焦虑症状相关。结论：这些发现加深了人们对身体自我意识的理解，建议在与 AN 患者的治疗互动中考虑 PPS，并将其作为解决社交障碍的潜在治疗目标。
