Children with paediatric feeding disorders may not naturally develop typical chewing skills to eat age-appropriate food textures. There are only a handful of studies on teaching chewing, and even less for children without any chewing history. Additional research is needed on increasing food texture and chewing skills, particularly internationally in settings outside of intensive specialised interdisciplinary hospitals. A 5-year-old male with avoidant/restrictive food intake disorder (ARFID), autism spectrum disorder, iron deficiency, low weight, and history of constipation who had never chewed (not even infant dissolvables) or eaten texture other than baby food in his life participated. He had failed treatment attempts by multiple disciplines for over 4 years, including a week-long inpatient interdisciplinary feeding hospitalisation. We used a modified multiple baseline probe across food textures design. After 3 weeks of solely behaviour-analytic treatment, Junot was eating (chewing and swallowing) a full plate of regular texture portions of a variety of 109 foods from all food groups. He learned to bite off, chew, lateralise, masticate, judge, and swallow a wide variety of regular texture foods, including some meats and raw fruit and vegetables. We trained his parents to implement the protocol with high integrity. He met all 100 % of goals. Parents reported high satisfaction and social acceptability and gains were maintained to 1-year follow-up.

患有小儿进食障碍的儿童可能不会自然地发展出典型的咀嚼能力，以吃不适合年龄的食物。很少有关于咀嚼教学的研究，对于没有咀嚼历史的孩子的研究甚至更少。需要进一步研究以提高食物的质地和咀嚼能力，特别是在国际上在密集的专业跨学科医院之外的环境中。一名5岁男性，患有回避性/限制性食物摄入障碍（ARFID），自闭症谱系障碍，铁缺乏症，体重轻和便秘史，从未咀嚼（甚至没有婴儿可溶性食品）或食用婴儿食品以外的质地他的生活参与了。他在多个学科的治疗尝试中失败了4年以上，包括为期一周的住院患者跨学科喂养住院治疗。我们在整个食物质地设计中使用了改进的多基线探针。在仅进行了3周的行为分析治疗后，朱诺特就吃了（咀嚼和吞咽）一盘整盘的规则纹理部分，这些部分来自所有食品类别的109种食品。他学会了咬咬，咀嚼，侧卧，咀嚼，判断和吞咽各种常规质地的食物，包括一些肉类以及未加工的水果和蔬菜。我们培训了他的父母以高度诚信的方式执行该协议。他实现了所有100％的目标。父母表示满意并获得社会认可，并获得了长达一年的随访。朱诺正吃着（咀嚼和吞咽）满盘的所有食物类别的109种食物中的常规质地部分。他学会了咬咬，咀嚼，侧卧，咀嚼，判断和吞咽各种常规质地的食物，包括一些肉类以及未加工的水果和蔬菜。我们培训了他的父母以高度诚信的方式执行该协议。他实现了所有100％的目标。父母表示满意并获得社会认可，并获得了长达一年的随访。朱诺特正在吃（咀嚼和吞咽）一盘整盘的规则纹理部分，这些部分来自所有食品组的109种食物。他学会了咬咬，咀嚼，侧卧，咀嚼，判断和吞咽各种常规质地的食物，包括一些肉类以及未加工的水果和蔬菜。我们培训了他的父母以高度诚信的方式执行该协议。他实现了所有100％的目标。父母表示满意并获得社会认可，并获得了长达一年的随访。
