Interpersonal psychotherapy was selected as the specialty
treatment because it is theoretically and procedurally
distinct from both BWL and CBTgsh and because it has a well - documented efficacy
in treating BED, depression, and negative affect.24 Our specific moderator hypothesis was that IPT would be the optimal
treatment in patients with high negative affect, with no
difference between IPT, BWL, or CBTgsh
in patients with low negative affect.
