“…Omission training, also known as differential reinforcement of other behavior (DRO), is a schedule of reinforcement in which reinforcers are delivered contingent on the nonoccurrence of a target response (Reynolds, 1961). Omission is commonly used to treat a wide variety of problem behavior including substance abuse (e.g., contingency management and the therapeutic workplace; Higgins et al, 1991;Silverman et al, 1996), medical noncompliance (e.g., Cuvo, Reagan, Ackerlund, Huckfeldt, & Kelly, 2010;Shabani & Fisher, 2006;Slifer, Avis, & Frutchey, 2008), and problem behavior common in individuals with developmental and intellectual disabilities (e.g., aggression, self-injurious behavior, and disruption; Iannaccone, Hagopian, Javed, Borrero, & Zarcone, 2019).
