Approximately 6 million children in the United States have a diagnosed food allergy, and 32% of caregivers experience significant psychological distress due to the diagnosis. Despite substantial impacts on psychosocial health and quality of life, few interventions aim to help caregivers of newly diagnosed children. There is a clear, unmet need for interventions to address caregiver distress, especially after the initial diagnosis.
We developed a mobile psychosocial health intervention, the Food Allergy Symptom Self-Management with Technology (FASST) app. Primary end points were to determine the app's feasibility and caregiver satisfaction.
This was a phase II, randomized controlled, implementation study (4-week duration) in caregivers (N = 30) of children ≤ 18 years of age who were newly diagnosed with a food allergy (≤90 days after the diagnosis). Caregivers (n = 20) were randomized to use the FASST app (intervention group) with access to individualized, self-help symptom relief interventions and food allergy support, and educational resources; or to use a limited app with a basic FASST interface and links to a few educational resources (control group [n = 10]). Ten participants (intervention group, n = 5; control group, n = 5) participated in semistructured interviews at week 4.
Both groups found the app relatively easy to use. The intervention group scores for safety preparedness during social activities increased by 24%, whereas those in the control group experienced a 1% decline. The intervention group participants increased the use of websites to find food allergy information by 17% at week 4 compared with 4% for the control group. Although the intervention group participants showed greater gains than did those in the control group in their confidence to prepare for and prevent allergic reactions, and greater declines in perceived social limitations, more participants in the control group endorsed confidence in their ability to recognize (11% versus 5%, respectively) and treat (10% versus 6%, respectively) allergic reactions.
Analysis of our results suggests that the FASST app may provide a feasible means of delivering psychosocial and educational supports to caregivers of children recently diagnosed with a food allergy.Clinical trial NCT04512924, www.clinicaltrials.gov.
美国约有600万儿童被诊断出患有食物过敏，32%的照顾者因这一诊断而经历严重的心理困扰。尽管对心理社会健康和生活质量有重大影响，但很少有干预措施旨在帮助新诊断儿童的照顾者。显然，迫切需要采取干预措施来解决照顾者的困扰，尤其是在初次诊断之后。
我们开发了一种移动心理社会健康干预措施，即食物过敏症状自我管理技术（FASST）应用程序。主要终点是确定该应用程序的可行性和照顾者满意度。
这是一项针对18岁及以下新诊断出食物过敏（诊断后≤90天）儿童的照顾者（N = 30）进行的II期随机对照实施研究（为期4周）。照顾者（n = 20）被随机分配使用FASST应用程序（干预组），可以获得个性化的自助症状缓解干预措施、食物过敏支持和教育资源；或使用具有基本FASST界面并链接到一些教育资源的有限应用程序（对照组[n = 10]）。10名参与者（干预组，n = 5；对照组，n = 5）在第4周参加了半结构化访谈。
两组都发现该应用程序相对易于使用。干预组在社交活动期间的安全准备得分提高了24%，而对照组则下降了1%。与对照组的4%相比，干预组参与者在第4周时使用网站查找食物过敏信息的比例增加了17%。尽管干预组参与者在为过敏反应做准备和预防方面的信心比对照组有更大提高，并且在感知到的社会限制方面有更大下降，但对照组中更多参与者认可自己识别（分别为11%和5%）和治疗（分别为10%和6%）过敏反应的能力。
对我们结果的分析表明，FASST应用程序可能为向最近被诊断出患有食物过敏儿童的照顾者提供心理社会和教育支持提供一种可行的方式。临床试验NCT04512924，www.clinicaltrials.gov。
