Abstract

Habits are behavioural routines that are automatic and frequent, relatively independent of any desired outcome, and have potent antecedent cues. Among individuals with anorexia nervosa, behaviours that promote the starved state appear habitual.

Discussion

Maladaptive behaviours characteristic of anorexia nervosa are cue-dependent, consistent with relying on mechanisms underlying habits. The habit strength of these behaviours is modifiable.

REaCH is a treatment tool that essentially ‘zooms in’ on the behavioural routines experienced as highly automatic by individuals with anorexia nervosa. It emphasizes fine-grained behavioural analysis, antecedent and in-the-moment cues, and proximal rewards.
