There is a dearth of research on suicidal thoughts and behaviors among eating disorder patients diagnosed with binge eating disorder (BED) or other specified feeding or eating disorder (OSFED). This pilot study evaluated presence and severity of suicidal thoughts and behaviors by eating disorder diagnosis in a transdiagnostic clinical eating disorder sample.

Participants were individuals (N = 257; 91.1% female; 94.6% Caucasian) currently receiving eating disorder treatment for anorexia nervosa (AN), bulimia nervosa (BN), BED, or OSFED. Participants completed online measures of variables.

Lifetime and current presence and severity of suicidal ideation and suicide attempts were statistically similar among diagnostic groups.

Though largely overlooked, treatment‐utilizing individuals with BED and OSFED may experience elevated rates and severity of suicidal thoughts and behaviors, like those with AN and BN. Attention to suicide‐related risk assessment and management is needed when treating individuals with eating disorders, regardless of diagnosis.

Research has established pairwise relationships between suicidal ideation (SI), low Body Trust, elevated agitation, and eating disorders, but knowledge of how these aspects relate in a single model is lacking. This study tested an indirect pathway with low Body Trust relating to severity of SI via agitation in a clinical eating disorder sample.

Participants (N= 319; 92.8% female; 93.4% Caucasian; mean age 21.8 years) were adults currently receiving specialized eating disorder treatment (44.3% intensive outpatient or higher level‐of‐care) who completed online self‐report measures of study variables. The PROCESS macro was utilized to test proposed pathways.

Low Body Trust was significantly directly associated with increased severity of current SI, both before (B= −.89,p <.001) and after (B= −.51,p =.001) accounting for the indirect effect through agitation, also significant (B= −.37,SE= .06, CI −.52 to −.26).

Perception of the body as unsafe may be related to agitation, and this intolerable sensation of trapped arousal could contribute to a desire to die. Future work should investigate these relationships prospectively to determine the relevance of Body Trust for assessment and treatment of suicide‐related factors among individuals with eating disorders.
