Behavioral interventions have had limited success in managing the chronic hyperphagia and obesity that are of presumed organic etiology in Prader-Willi syndrome. Thus, frequent foraging for food and covert consumption continue to be health-threatening problems for many Prader-Willi individuals. This case study was designed to replicate methods for assessment and treatment of food theft. A token program based on differential-reinforcement-of-other-behavior and response-cost eliminated theft in three hospital settings. Prior to discharge, the program was expanded to include contingencies on exercise behavior and weight loss, and staff from the subject's group home residence were trained to implement a modified program in the natural environment. Reduced food theft and continued weight loss were maintained in the group home and an apartment-living arrangement. A total of 81 lb (37 kg) was lost during a 2-yr period.
行为干预在管理普拉德-威利综合征中假定为器质性病因的慢性食欲亢进和肥胖方面成效有限。因此，频繁觅食和秘密进食对许多普拉德-威利综合征患者来说仍然是威胁健康的问题。本案例研究旨在复制食物盗窃评估和治疗方法。一个基于其他行为的差别强化和反应代价的代币计划在三个医院环境中消除了盗窃行为。出院前，该计划扩大到包括对运动行为和体重减轻的应急措施，并且来自受试者集体家庭住所的工作人员接受培训，以便在自然环境中实施修改后的计划。在集体家庭和公寓居住安排中，食物盗窃减少且体重持续减轻。在两年期间共减轻了81磅（37千克）体重。
