- Abstract
- Difficulties in perspective taking (PT), are well-documented in patients with anorexia nervosa. This study aimed to assess PT among restrictive (AN-R) and binge/purge subtype (AN-B/P) of anorexia nervosa using the Level-2 Visual Perspective-Taking (VPT) task that isolates PT processes: self-other distinction, self-other priority, altercentric bias, and egocentric bias. A total of 172 women (88 healthy controls, 56 AN-R, 28 AN-B/P) completed the Level-2VPT task. Subtype-specific PT biases emerged with a significantly greater altercentric bias in patients with AN-R, reflecting difficulty in maintaining their own perspective when it differs from another’s. Conversely, patients with AN-B/P showed an increased egocentric bias, indicating difficulty in inhibiting their own perspective when it differs from another’s perspective. These distinct PT biases may represent subtype-specific vulnerabilities: overreliance on others’ perspectives in AN-R and a dominant self-focus in AN-B/P. The findings highlight the necessity of distinguishing between AN subtype in both research and clinical contexts.
