Assent is generally defined as a willingness to participate. In ABA, we think of this as the client's participation in therapy. Ethically, we are mandated to gain consent and often times this happens when a parent or guardian gives consent to treat the client. When we talk about assent, we are talking about the client themselves willingness to participate. Smith and Breaux (2023) analyzed multiple definitions of assent across disciplines and found common features within definitions. General theme is the agreement to participate. Other common features include voluntary and without coercion. This is critical in understanding the intricacies of contingencies in place between clinicians and their learners.
