Development and early implementation of a brief 2-day multidisciplinary parent training group for paediatric ARFID: A feasibility and acceptability study

This is the authors' abstract. We don't add key points for this paper.

OBJECTIVE: Many children with avoidant/restrictive food intake disorder (ARFID) cannot access appropriate care, as existing individual and family treatments are scarce, long and costly. We developed a brief 2-day (12-h) multidisciplinary parent training group and assessed its feasibility and acceptability in routine care. METHOD: Single-arm implementation study in one tertiary centre. Parents of 18 children (5-14 years) with DSM-5 ARFID (17/18 sensory-based; non-French-speaking families excluded) attended two days three weeks apart. Guided by the RE-AIM framework, we assessed reach, feasibility (a priori benchmark ≥75% completion) and acceptability (HAQ-11S; CSQ-8; parents' written feedback). Clinician-rated severity (CGI-S) was an exploratory, uncontrolled signal. Parents' immediate self-reports most often cited better understanding of the disorder, increased competence and reduced isolation. CGI-S was numerically lower afterwards but this uncontrolled change cannot be attributed to the intervention. CONCLUSION: This brief multidisciplinary parent group for paediatric ARFID is feasible and highly acceptable in this specialist setting, resource use and clinical benefit require controlled evaluation.
