Two studies demonstrated a functional relationship between a peer modeling procedure and the treatment of feeding disorders with 2 young children. In the first experiment, the use of a peer model treatment package was shown to induce swallowing in a child with dysphagia who had never swallowed food or liquid. In the second experiment, a child who consistently declined food was induced to increase food acceptance as a function of the same peer modeling package. In the latter experiment, a peer-mediated procedure, consisting of rotated opportunities to consume food with a peer, was found to increase consumption more than did modeling alone. The first experiment used a multiple baseline design across solids and liquids, and the second used a multiple treatment design. The results of both experiments are discussed as new and nonaversive treatments for feeding disorders of young children who are imitative. 相似文献

A treatment package was used to induce and maintain swallowing with three infants who did not swallow food or liquid. Prior to treatment, they received all nutrition and hydration via gastrostomy tube feedings. The treatment package consisted of least-to-most intrusive physical prompts, an eliciting stimulus, contingent social reinforcement, and repeated trials to induce and maintain swallowing. The design combined elements of reversal and changing criterion designs for all three infants. The package was applied across feeding devices (nipple, cup, spoon), situations (liquid, pureed foods), and persons (trainer, primary nurses, mothers). The number of swallows or ounces per feeding (from 0 to 8 ounces) and the number of feeding sessions per day (from one to five) were progressively increased. In each case, the infant received baseline conditions alternated with the treatment package. Follow-up probes were done at 15 months, 21 months, or 24 months, respectively, after the last phase for the three patients. The package was successful in that the gastrostomy tube was no longer needed for Patients 1 and 3. Patient 2 maintained functional swallowing responses but received supplemental gastrostomy feedings because of unrelated medical problems. Results are discussed in terms of the need to isolate components of the package. The package can be used in cases in which the preexisting treatments (reinforcement with preferred foods, force-feeding) are not feasible because of age, physical fragility, or the lack of a swallowing response following the presentation of food. 相似文献
