项目摘要

Avoidant restrictive food intake disorder (ARFID) is a new psychiatric disorder in the Diagnostic and Statistical Manual 5 (DSM-5). ARFID has an estimated prevalence of 7.2 to 17.4 percent thus making it a significant mental health concern. ARFID is characterized by a range of dysfunctional eating behaviors including a lack of interest in eating, sensory related eating concerns (such as taste, color or texture) and a fear of adverse consequences of eating (i.e., fear of choking or vomiting). There is no evidence-based treatment for ARFID. Preliminary data from a feasibility study comparing FBT-ARFID to Usual Care (UC) provide evidence that manualized FBT adapted for patients with ARFID is feasible and effective. Recruitment and randomization averaged 1.87 participants per month over a 15 month period with an overall attrition rate of 21%, comparable to rates in fully powered studies of FBT-AN. The feasibility study also identified an efficacy signal on the difference between groups on the primary outcome (change in percent Estimated Body Weight (%EBW)) of a large effect size (ES) favoring FBT-ARFID Studies suggest that improvements in parental self-efficacy related to changing feeding and eating behaviors early in treatment is a likely mechanism of FBT for other eating disorders in youth. Our feasibility study showed a striking difference between conditions in parental self-efficacy favoring FBT-ARFID compared to UC. In addition to this promising evidence of target engagement In addition, target validation was demonstrated by the change in parental self-efficacy being significantly correlated with improvements in % EBW. Aim 1: To conduct an RCT involving children and adolescents between the ages of 6 and 12 years of age with DSM 5 ARFID and weight below 88% of EBW comparing FBT-ARFID with medical management to manualized Non-Specific Treatment UC with medical management. Treatments will be matched for time and therapist attention. We hypothesize that participants randomized to FBT-ARFID will have significantly greater change in %EBW at EOT. Aim 2: To examine early change in parental self-efficacy as a mediator of treatment effect (FBT-ARFID vs. UC on outcome). We hypothesize that positive changes due to FBT-ARFID in parental self-efficacy related to feeding behaviors using the Parents vs ARFID Scale (PvsARFID) will be associated with positive changes in %EBW at EOT. Secondarily, we will explore whether objective changes in parental re-feeding behavior is a possible mechanism of FBT-ARFID using a mediator analysis. Aim 3: To explore moderators of treatment outcome. To conduct an adequately powered study, 100 children (ages 6-12 years) will be randomized to manualized FBT-ARFID plus medical management (n=50) or manualized Non- Specific Treatment plus medical management (n=50). Assessments (blinded to treatment condition) of primary and secondary outcomes will be conducted at baseline, 1 month, 2 months, and 4 months (EOT).

回避性限制性食物摄入障碍（ARFID）是诊断和治疗领域的一种新的精神疾病。统计手册 5 (DSM-5)。 ARFID 的流行率估计为 7.2% 至 17.4%，因此使其成为重大的心理健康问题。 ARFID 的特点是一系列功能失调的饮食行为，包括对饮食缺乏兴趣、与感官相关的饮食问题（例如味道、颜色或质地）以及对不良反应的恐惧进食的后果（即害怕窒息或呕吐）。目前还没有针对 ARFID 的循证治疗方法。将 FBT-ARFID 与常规护理 (UC) 进行比较的可行性研究的初步数据提供了以下证据：适用于ARFID患者的手动FBT是可行且有效的。招募和随机化 15 个月内平均每月有 1.87 名参与者，总体流失率为 21%，可比 FBT-AN 的全动力研究中的比率。可行性研究还确定了一个功效信号组间主要结果的差异（估计体重百分比 (%EBW) 的变化）大效应量（ES）有利于 FBT-ARFID 研究表明，父母自我效能感的提高与在治疗早期改变喂养和饮食行为是 FBT 治疗其他饮食失调的一个可能机制在青春里。我们的可行性研究表明，父母自我效能感的条件之间存在显着差异 FBT-ARFID 与 UC 的比较。除了目标参与的这一有希望的证据之外，目标父母自我效能感的变化与 EBW 百分比的改进。目标 1：开展一项涉及 6 岁儿童和青少年的随机对照试验 12 岁，使用 DSM 5 ARFID，体重低于 EBW 88%（将 FBT-ARFID 与医疗设备进行比较）管理到手动非特异性治疗 UC 与医疗管理。治疗将进行匹配以获得时间和治疗师的关注。我们假设随机接受 FBT-ARFID 的参与者将有 EOT 时 %EBW 变化显着更大。目标 2：检查父母自我效能感的早期变化治疗效果的中介变量（FBT-ARFID 与 UC 对结果的影响）。我们假设积极的变化是由于使用父母与 ARFID 量表 (PvsARFID) 评估与喂养行为相关的父母自我效能感中的 FBT-ARFID 将与 EOT 时 %EBW 的积极变化相关。其次，我们要探讨是否客观使用中介分析，父母重新喂养行为的变化是 FBT-ARFID 的一个可能机制。目的 3：探索治疗结果的调节因素。为了进行一项充分有力的研究，100 名儿童（年龄 6-12 岁）将被随机分配到手动 FBT-ARFID 加医疗管理（n = 50）或手动非特殊治疗加医疗管理 (n=50)。主要评估（对治疗条件不知情）次要结局将在基线、1 个月、2 个月和 4 个月 (EOT) 时进行。
