The effect of Differential Reinforcement of Incompatible Behaviors (DRI) on pica for cigarettes in two intellectually disabled adults was studied using an A-B-A-B treatment design; in addition, the efficacy of using placebo pica stimuli (bread "cigarette butts") was evaluated. Both subjects received 10 15-minute sessions of baseline followed by 10 sessions of DRI, with a reversal to baseline and a repeat of the DRI treatment. Results support the efficacy of DRI with pica, as well as the use of placebo pica stimuli. Generalization was conducted with one of the subjects; results indicate that treatment effects were present when implemented by several ward personnel. The implications of the results for future research were discussed.
采用A - B - A - B治疗设计，研究了不相容行为差别强化（DRI）对两名智力残疾成年人香烟异食癖的影响；此外，还评估了使用安慰剂异食癖刺激物（面包“烟头”）的效果。两名受试者均接受了10次15分钟的基线期，随后是10次DRI治疗期，之后恢复到基线期并重复DRI治疗。结果支持DRI对异食癖的疗效，以及安慰剂异食癖刺激物的使用。对其中一名受试者进行了泛化研究；结果表明，由几名病房工作人员实施治疗时，治疗效果存在。讨论了研究结果对未来研究的启示。
