Abstract

Objective

Accessible treatment options for avoidant/restrictive food intake disorder (ARFID) in children are limited. The current study sought to assess acceptability, feasibility, and preliminary efficacy of a brief, virtual intervention for ARFID in children (“ARFID-PTP”).

Method

Families of children ages 5–12 with ARFID (n = 30) were randomized to immediate or waitlist treatment groups, with both groups ultimately receiving ARFID-PTP. ARFID-PTP consists of two, 2-h individual treatment sessions with an optional booster session at 4-week follow-up. Families completed acceptability and feasibility measures at end-of-treatment, as well as preliminary efficacy measures at 4-week, 3-month, and 6-month follow-up.

Results

Of 30 families who completed an intake session, 27 (90%) completed treatment. Families rated acceptability as high (M _CEQ-C = 7.75). Treatment was feasible by participant retention. Exposure adherence was lower than expected, and booster session requests were higher than expected, indicating that achieving feasibility across measures may require treatment modifications. Regarding preliminary efficacy, children in the immediate treatment group had a decrease in ARFID symptoms compared to those on the waitlist. Overall, at 6-month follow-up linear mixed models showed participants had significantly reduced ARFID symptoms by presentation (p < 0.05) and in follow-up completers, children incorporated eight new foods on average.

Discussion

ARFID-PTP is acceptable and preliminarily efficacious. The protocol may benefit from modifications to increase feasibility; however, booster session content and treatment outcomes suggest a priori feasibility markers may not accurately capture the utility of ARFID-PTP. Further work should continue to examine the efficacy ARFID-PTP, particularly in diverse samples where treatment accessibility is urgently needed.

ARFID 家长培训计划（"ARFID-PTP"）：评估针对回避型/限制型食物摄入障碍的简短家长培训计划的随机试点试验结果》（Randomized Pilot Trial Results of A Brief, Parent-Training Program for Avoidant/Restrictive Food Intake Disorder）。

目的：针对儿童回避型/限制型食物摄入障碍（ARFID）的可及治疗方案非常有限。本研究旨在评估针对儿童 ARFID 的简短虚拟干预（"ARFID-PTP"）的可接受性、可行性和初步疗效：方法：5-12 岁 ARFID 儿童的家庭（n = 30）被随机分配到即时治疗组或候补治疗组，两组最终都接受 ARFID-PTP 治疗。ARFID-PTP包括两节2小时的个人治疗课程，并在4周的随访中提供一次可选的强化课程。家庭在治疗结束时完成可接受性和可行性测量，并在4周、3个月和6个月的随访中完成初步疗效测量：结果：在 30 个完成接受治疗的家庭中，27 个（90%）完成了治疗。家庭对治疗的可接受性评价很高（MCEQ-C = 7.75）。通过保留参与者，治疗是可行的。暴露坚持率低于预期，加强治疗的要求高于预期，这表明要实现各项措施的可行性，可能需要对治疗方法进行修改。在初步疗效方面，与等待治疗组相比，立即治疗组儿童的ARFID症状有所减轻。总体而言，在 6 个月的随访中，线性混合模型显示参与者的 ARFID 症状明显减少（p 讨论）：ARFID-PTP是可以接受的，并具有初步疗效。对方案进行修改以提高可行性可能会使其受益；然而，强化训练内容和治疗结果表明，先验的可行性指标可能无法准确反映 ARFID-PTP 的效用。应继续开展进一步工作，研究ARFID-PTP的疗效，尤其是在急需获得治疗的不同样本中的疗效：试验注册：ClinicalTrials.gov identifier：NCT04913194.

期刊介绍： Articles featured in the journal describe state-of-the-art scientific research on theory, methodology, etiology, clinical practice, and policy related to eating disorders, as well as contributions that facilitate scholarly critique and discussion of science and practice in the field. Theoretical and empirical work on obesity or healthy eating falls within the journal’s scope inasmuch as it facilitates the advancement of efforts to describe and understand, prevent, or treat eating disorders. IJED welcomes submissions from all regions of the world and representing all levels of inquiry (including basic science, clinical trials, implementation research, and dissemination studies), and across a full range of scientific methods, disciplines, and approaches.
