Children with feeding disorders often display severe food selectivity. For many of these children, consuming highly textured foods may be aversive or potentially dangerous because of frequent gagging. The purpose of this study was to demonstrate the efficacy of texture fading in the treatment of food selectivity displayed by 4 children. Treatment involved the gradual addition of higher textures based on the results of periodic probes. In addition, food acceptance and swallowing were reinforced, while food refusal and food expulsion were placed on extinction. Results showed that all participants successfully advanced to consumption of age-appropriate texture and volume. The results suggest that texture fading with intermittent probes at higher textures may be an effective method for the treatment of food selectivity by texture.
患有喂养障碍的儿童通常表现出严重的食物选择性。对于这些儿童中的许多人来说，由于频繁出现作呕现象，食用质地较硬的食物可能会引起反感或有潜在危险。本研究的目的是证明质地渐变法对4名儿童所表现出的食物选择性的治疗效果。治疗方法是根据定期探查的结果逐渐增加食物的质地。此外，对接受和吞咽食物的行为给予强化，而对拒绝和吐出食物的行为则不予理会。结果显示，所有参与者都成功地过渡到食用适合其年龄的质地和量的食物。结果表明，采用较高质地的间歇性探查的质地渐变法可能是治疗因质地引起的食物选择性的一种有效方法。
