A Longitudinal Examination of the Relationship between Eating Disorder Symptoms and Suicidal Ideation

Ortiz, Shelby Noelle

Abstract Details

2019, Master of Arts, Miami University, Psychology.
There is an assumption that eating disorders (EDs) serve as a risk factor for – and therefore, precede – suicidal thoughts and behaviors (STBs). However, because most studies investigating the ED-STB link have been limited to cross-sectional or retrospective designs, this assumption has not been adequately tested. There are other limitations with previous work that must be addressed. First, the mean follow-up time for the few longitudinal studies that exist was nearly a decade. Moreover, only one study has examined whether an ED factor (i.e., diagnosis or symptom) longitudinally predicts suicidal ideation. Even within cross-sectional studies, suicidal ideation has been poorly measured, with most studies using only one item to assess suicidal ideation. Thus, the present study used autoregressive cross-lagged modeling to test if a bidirectional relationship exists between ED symptoms and suicidal ideation among an ED patient sample over five weekly time points. Results revealed that suicidal ideation and ED symptoms were associated with each other at each time point. Additionally, suicidal ideation at Week 3 predicted ED symptoms at Week 4, while controlling for Week 3 ED symptoms. Given that suicidal ideation may influence future engagement in ED symptoms, targeting suicidal thoughts in therapy may help to reduce eating pathology.
