Diagnostic, clinical, and personality correlates of food anxiety during a food exposure in patients diagnosed with an eating disorder
Eating disorders are characterized by high levels of anxiety, especially while eating. However, little is known about anxiety experienced during meals and specifically what other variables may impact such anxiety.
We sought to further quantify and understand the relationship between food anxiety, eating disorders, and related correlates (e.g., comorbid diagnoses, personality).
In the current study [N = 42 participants diagnosed with an eating disorder (n = 36 participants with anorexia nervosa)], we quantified anxiety before, during, and after a meal using data from a food exposure session in a partial hospital eating disorder center. We examined diagnostic, personality, and clinical factors as correlates of food anxiety.
Participants were more likely to experience higher food anxiety if they had a current diagnosis of major depression, obsessive–compulsive disorder, or post-traumatic stress disorder (PTSD). Concern over mistakes was the strongest and most consistent correlate of food anxiety regardless of time during the meal that anxiety was assessed. Other significant correlates were fear of positive evaluation, social appearance anxiety, BMI, and trust.
These findings show how diagnoses, perfectionism (concern over mistakes), and other correlates relate to anxiety during meals. Food exposure interventions may benefit from personalizations that address these factors.
