A longitudinal, momentary examination of interpersonal stress, inhibitory control, binge eating, and nonsuicidal self-injury PROJECT SUMMARY/ABSTRACT Eating disorders are associated with numerous, severe medical and psychological problems, including suicidal behaviors that lead to premature mortality. Approximately one-quarter to one-third of people with eating disorders have thought about and/or attempted suicide and an estimated quarter to half of individuals with eating disorders engage in nonsuicidal self-injury (NSSI). Currently, the best available treatments for adults with eating disorders produce moderate remission rates and high dropout and relapse rates and do not have components targeting commonly co-occurring suicidal behaviors (e.g., NSSI). Thus, it is essential to develop a better understanding of eating disorders and the suicidal behaviors that often accompany them, so that we can develop more effective treatments. Eating disorder and NSSI research have both consistently found that interpersonal stress increases the risk of engaging in these dysregulated behaviors. Additionally, the scientific literature has linked low inhibitory control to eating disorder and suicidal behaviors. This project proposes to test the Interpersonal Model of Dysregulated Behaviors, which hypothesizes that high momentary interpersonal stress and low momentary inhibitory control lead to eating disorder and suicidal behavior. The model will be tested in a sample of college freshmen (due to this being a vulnerable period of time for the onset of eating disorder and suicidal behavior). Ecological momentary assessment protocols used at the beginning and end of freshman year will be used to test predictions about inhibitory control, interpersonal stress, and the interplay between the two variables in the prediction of subsequent binge eating and NSSI behavior. Achieving the aims of the study will deepen knowledge about the etiology and course of binge eating and NSSI over time. Importantly, the results will have implications for creating novel interventions that more effectively target these behaviors than existing treatments.
