Introduction

Previous research from our group showed that, after a single yoga class, Interoceptive Accuracy (IAc), tested through the Heartbeat Counting Task, improved in a group of Healthy Controls (HC), but not in a group of patients with Anorexia Nervosa (AN).

Objectives

To evaluate three levels of interoception (accuracy, confidence (IC) and awareness (IAw)) before and after eight sessions of Yoga in a sample of patients with Eating Disorders (ED: AN, Bulimia Nervosa (BN) and Binge Eating Disorder (BED)).

Methods

15 patients with ED were included. Before the first yoga session (T0) and 72 hours after the last session (T1), participants underwent: (i) the Heartbeat Counting Task for the evaluation of IAc, IC and IAw; (ii) a psychometric assessment evaluating depression, anxiety, body awareness, alexithymia, self-objectification and eating disorders symptomatology.

Results

At T1, ED patients’ IAc appeared higher than at T0, but not IC and IAw. A trend towards significance (p = 0.055) emerged for the interaction effect between IAc and diagnosis, with BED patients having a higher increase of IAc at T1 than AN and BN patients. Significant correlations between IAc and Alexithymia, Anxiety and Depression emerged at T0, but were not maintained at T1.

Conclusions

After a program of eight Yoga sessions, IAc in ED patients (but not IC and IAw) increases, especially in BED patients. Moreover, the improvement of IAc following the yoga course seems to be unrelated to the course of depressive, anxious and alexithymic symptoms of ED patients.
