A parent\u2010only guided self\u2010help version of FBT (GSH\u2010FBT) demonstrated preliminary efficacy in pilot investigations. To address challenges in access to care, we adapted GSH\u2010FBT into a parent\u2010only multi\u2010family group format (MF\u2010GSH\u2010FBT) delivered via videoconferencing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>This report details the feasibility and acceptability of a parent\u2010only group\u2010based multi\u2010family GSH\u2010FBT (MF\u2010GSH\u2010FBT) for adolescent AN delivered virtually. The MF\u2010GSH\u2010FBT intervention consisted of 12 weekly 60\u2010min sessions facilitated by a clinician in addition to online FBT video content and recommended readings. Adolescents and parents completed assessments at baseline and post\u2010treatment.

Four consecutive cohorts of groups of 3\u20134 families were completed from April 2022 to April 2023. Across cohorts, parents attended 85% of sessions. Most parents rated the treatment sessions as helpful (79%; agree\/strongly agree) and felt supported by the other group members (84%). All parents (100%) reported MF\u2010GSH\u2010FBT helped their child, and most (90%) reported their child had improved by end\u2010of\u2010treatment. On average, adolescents gained 3.53\u2009kg (SD: 3.76) from pre\u2010 to post\u2010treatment, with percent estimated mean body weight increasing 5% on average. Parental self\u2010efficacy also increased from baseline to end\u2010of\u2010treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>MF\u2010GSH\u2010FBT for AN appears feasible and acceptable to parents participating in this pilot study.
