OBJECTIVE: Evidence points towards heightened anxiety and attention biases (AB) towards disorder-specific (threatening) stimuli in patients with anorexia nervosa (AN). To date, it is unclear how anxiety and AB interact in eating disorders (ED). The present study tests the causal role of anxiety by inducing anxiety before a dot-probe task with either ED-specific stimuli or unspecific negative (threat-related) information. We expected that anxiety would elicit AB for ED-specific, but not for unspecific threat-related stimuli.
METHODS: Adolescents with AN (AN, n = 32) or depression (DEP, n = 27) and healthy controls (HC, n = 29) underwent an anxiety induction or a low anxiety control task before a pictorial dot-probe task with either under-/overweight body-related pictures or non-disorder-related threatening pictures (angry faces). BMI, level of ED symptoms, anxiety, stress, and depression were assessed at baseline.
RESULTS: The anxiety induction did not affect the observed attention pattern. AN showed an AB towards underweight body pictures compared to HC, whereas no disorder-unspecific threat-related AB emerged. Regression analyses revealed that only anxiety predicted the AB towards underweight body pictures.
DISCUSSION: Further experimental research may integrate eye tracking as an additional tool, or collect information on body dissatisfaction to obtain a better understanding of how anxiety biases attention.
