Items on the IE-ACF were coded by two independent coders as either present or absent with therapists considered adherent if both independent coders coded the item as \u201cpresent.\u201d Videotaped sessions of FBT-IE of 30 adolescents with low-weight eating disorders (DSM-5 typical\/atypical anorexia nervosa) and their families were coded. Participants received the FBT-IE intervention as part of a randomized controlled trial.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Seventy FBT-IE videos were coded. The IE-ACF identified a mean (SD) rating of 80% (\u00b15%) therapist adherence to the protocol across the six-session treatment, with a per item adherence ranging from 36\u2013100%. Two independent coders demonstrated moderate to almost perfect inter-rater reliability (\u03ba range 0.78\u20130.96) across the sessions.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>IE-ACF measured therapist adherence to our novel FBT-IE treatment for adolescents with low-weight eating disorders. Through this study, we demonstrated that 1) our therapists were adherent to the FBT-IE manual in the context of an ongoing clinical trial and 2) that independent coders reliably coded sessions using our novel
