Endorsement of Avoidant/Restrictive Eating Motivations Across Restrictive Eating Disorders: A Trait- and State-Level Examination.

ABSTRACT:

Objective

Research on avoidant/restrictive food intake disorder (ARFID) and anorexia nervosa (AN) has emphasised differences between these disorders, but similarities maintaining dietary restriction may be overlooked. ARFID-related eating disturbances may also occur and facilitate egosyntonic restriction in AN.

Method

Using the Nine Item ARFID Screen (NIAS; N = 141) and ecological momentary assessment (N = 76), we examined endorsement of ARFID-related and traditional eating disorder (ED) reasons for restrictive eating in women with ARFID, AN-restrictive subtype (AN-R), AN binge eating/purging subtype (AN-BP), and controls.

Results
