The open versus blind weight conundrum: A multisite randomized controlled trial across multiple levels of patient care for anorexia nervosa.

Anorexia nervosa (AN) is a disorder characterized by a profound fear of weight gain, resulting in significant weight loss, as well as behavioral symptoms that interfere with weight normalization. In concert, weight gain remains a proximal goal of treatment, and patient weighing is a critical component of treatment. However, divergent approaches exist in how patient weighing is undertaken in clinical practice. The aim of this study is to investigate the impact of a brief course of open weighing (sharing weight data with patients) versus blind weighing (not sharing weight data with patients) on distress around being weighed and AN symptom severity.
