Common approaches to pica treatment involve intensive staffing and near continuous behavioral monitoring to proactively disrupt any attempts at this potentially life threatening behavior. Including differential reinforcement of discarding pica items as a contingency in such interventions has been suggested as a more practical treatment model, but the evidence base for this approach is limited. We replicated this work by evaluating differential reinforcement for discarding pica items in conjunction with response blocking and differential reinforcement of other behavior in the treatment of pica exhibited by two children. We extended this work by evaluating sustained reductions when therapist and caregiver monitoring was reduced.
异食癖治疗的常见方法包括密集人员配备和近乎持续的行为监测，以主动打断任何这种可能危及生命行为的尝试。有人提出，在这种干预措施中将丢弃异食癖物品的差别强化作为一项应急措施，作为一种更实用的治疗模式，但这种方法的证据基础有限。我们通过评估在治疗两名儿童表现出的异食癖时，将丢弃异食癖物品的差别强化与反应阻断及其他行为的差别强化相结合，重复了这项工作。我们通过评估在减少治疗师和照料者监测时能否持续减少异食癖行为，对这项工作进行了扩展。
