Objective:

Binging and purging are transdiagnostic features of eating disorders (EDs). Attentional biases (ABs) toward food and body shape cues and negative affect (NA) are associated with ED psychopathology. These ABs might also be present in people with subthreshold ED not meeting full diagnostic criteria. We investigated ABs to food and body shape cues and the interaction between ABs and NA in young people with binge/purge behavior (B/P group) and healthy controls (HC group). Our B/P sample consisted of individuals with threshold and subthreshold ED, including participants with BN, AN-R, and AN-B/P.
Method:

We conducted two studies. Study 1 recruited n = 54 HC and n = 53 B/P participants aged 16–25, and Study 2 recruited n = 73 HC and n = 72 B/P participants. In Study 1, ABs toward food and body shape cues were compared between B/P versus HC participants using a pictorial dot-probe task. In Study 2, ABs were compared between B/P versus HC participants after NA induction using the Cyberball social exclusion task. Indexes of attentional engagement and disengagement were computed.
Results:

There was a main effect of cue type on attentional engagement at 0.2 s (p = 0.006, n2p = 0.075) and 2 s (p = 0.040, n2p = 0.043), and attentional disengagement at 2 s (p = 0.006, n2p = 0.077) in Study 1. Findings were not replicated following NA induction in Study 2. No main effect of group or group × cue type interaction was found.
Discussion:

Our results disagree with previous research supporting the importance of ABs toward food and body shape cues in young people with threshold and subthreshold EDs and suggest these might not constitute a relevant target in the treatment of ED behavior. However, due to a heterogeneous approach to measuring ABs and multiple types of AB being described in EDs, further research is needed to clarify whether ABs map onto transdiagnostic models of behavioral dysregulation.
