Which characteristic emphasizes the use of research-based methods in ABA?

The characteristic that emphasizes the use of research-based methods in Applied Behavior Analysis (ABA) is technological. This characteristic highlights the importance of having procedures that are described in detail so that they can be replicated and verified by others. By adhering to a technological framework, practitioners ensure that their interventions are grounded in empirical evidence and can be systematically applied across different contexts or by different practitioners. This promotes consistency and fidelity in implementation, ensuring that the methods used are not only practical but also validated by research and scientific inquiry. Such an approach is critical in ABA, as it underscores the commitment to using methods that have been shown to be effective through rigorous testing and evaluation, ultimately aiming for positive outcomes for clients.
