Yep
specific Alternative(s), typically (and desirably) functionally equivalent to the problematic behavior you're trying to decrease.
Those are the most common, but you can also reinforce low (DRL) or diminishing (DRD) rates of the problematic behavior, as well as specific rates (or above minimum rates) of an alternate or incompatible behavior (DRH, with the H generally standing for High). There are also variations/parameters on when reinforcement is available or delivered (e.g. momentary vs. whole-interval DRO; spaced-responding with a DRL). Choosing the correct interval (e.g., based on average baseline inter-response times is also crucial for effective use of any interval-based DR procedure) is also crucial. Additionally, as the DR program is often meant to be implemented by someone other than a behaviorally trained clinician, knowledge of the research regarding social validity, ease of implementation, and treatment fidelity can't be overlooked.
I don't say all this to sound smart, but more to emphasize that that differential reinforcement in a lot more complicated a topic than most non-behaviorally trained clinicians realize. It represents a major portion of the semester in graduate training in ABA. Sure, you can accomplish a lot with just a DRA/I, but knowledge of other concepts and applications is crucial for optimizing treatment effectiveness and efficiency. I can't tell you how many times I've seen people label and entire DR program as ineffective (often as a step to implementing something more aversive) or conclude that a reinforcer is ineffective, when in fact it's just a matter of adjusting the interval to increase/decrease access to reinforcers or switching to a momentary schedule to make the program more likely to be implemented properly.
