Objectives We aimed to determine whether decision-making impairment is an endophenotype of AN. We hypothesized that decision-making alteration would not respect the criteria of an endophenotype, and that these alterations would have a relationship with illness severity.

Prospective Valence Learning model (PVL) was employed to distinguish the cognitive dimensions underlying the decision-making process.
