Interoception and Self-Injurious Thoughts and Behaviors among Adults with Restrictive Eating Disorders

In healthy adults, instability in interoception, or variability in the extent to which one feels connected to one’s body, predicts engagement in self-injurious thoughts and behaviors (SITBs). However, it is unclear whether these findings would generalize to individuals with restrictive eating disorders and/or those at elevated risk for suicide. Leveraging 21 days of ecological momentary assessment data (105 timepoints), this study will evaluate whether short-term instability in interoception predicts a variety of SITBs in sample of adults with Anorexia Nervosa spectrum disorders (i.e., Anorexia Nervosa, Atypical Anorexia) and current or lifetime suicidality.
