These answers draw in part from “Connecting with Children During Difficult Moments: Tools for Honoring Assent and Assent Withdrawal” (Do Better Collective), and extend it with peer-reviewed research from our library of 27,900+ ABA research articles. Clinical framing, BACB ethics code references, and cross-links below are synthesized by Behaviorist Book Club.
View the original presentation →Consent is a legal concept exercised by a parent, guardian, or legally authorized representative who has the capacity to understand the proposed services and make an informed decision. Assent is the learner's own expressed willingness to participate in therapeutic activities. For children and individuals who cannot provide legal consent, assent is communicated behaviorally through indicators such as approach behavior, engagement with materials, and absence of distress.
The BACB Ethics Code (2022) requires practitioners to obtain both informed consent from the authorized representative and assent from the client to the extent possible, recognizing that both are necessary components of ethical practice.
Assent withdrawal in nonverbal learners is communicated through behavioral indicators that should be individualized for each learner. Common indicators include turning away from the practitioner or materials, pushing materials away, attempting to leave the area, going limp or rigid, crying or distress vocalizations, covering ears or eyes, hitting or biting themselves, increased stereotypy or self-stimulatory behavior, and facial expressions indicating distress. It is critical to establish a learner-specific profile of assent withdrawal indicators in collaboration with the family and document it in the treatment plan so that all team members can respond consistently.
No. Honoring assent withdrawal does not mean withdrawing all demands at the first sign of resistance. It means recognizing the learner's communication, responding with empathy and respect, and using clinical judgment to determine the appropriate response.
For mild resistance, acknowledgment plus scaffolding may be sufficient. For moderate resistance, modifying the demand while maintaining the therapeutic interaction is often appropriate. For signs of genuine distress, withdrawing the demand and reconnecting with the learner takes priority.
The key is that the practitioner's response is thoughtful and individualized rather than reflexive, and that the learner's communication is treated as meaningful.
This is one of the most challenging clinical judgments in ABA practice. Consider the intensity and quality of the response: mild protests with continued engagement suggest preference rather than distress, while intense distress behaviors suggest genuine withdrawal. Consider the context: resistance specific to one overly difficult program may reflect a poor instructional match, while generalized resistance may indicate broader distress.
Consider the learner's history and baseline: a sudden change in behavior warrants more careful attention than a long-standing pattern. Also consider physiological indicators such as flushed skin, rapid breathing, or elevated heart rate. This distinction requires ongoing clinical judgment and cannot be reduced to a simple rule.
This is a common concern. If assent withdrawal is honored indiscriminately, reinforcement of escape behavior is possible. However, assent-centered practice is not the same as providing unconditional escape.
The practitioner acknowledges the learner's communication, provides a brief pause, uses connection strategies, and then returns to the therapeutic activity in a modified form. Over time, learners who experience their communications as respected tend to show increased engagement and tolerance for demands because the therapeutic relationship serves as a protective factor. The research on therapeutic alliance across helping professions consistently shows that responsive, respectful interactions produce better long-term outcomes.
Begin by understanding the parent's perspective and concerns. Some parents may worry that honoring assent withdrawal will slow their child's progress or teach the child that protesting gets them out of work. Acknowledge these concerns as valid while explaining the evidence and rationale for assent-centered practice.
Share data showing that responsive approaches support long-term engagement and skill acquisition. Offer to collaborate on setting parameters, such as identifying specific indicators that warrant different responses. Code 2.09 requires involving stakeholders in treatment decisions, so working toward a shared understanding is both ethically required and practically beneficial.
Multiple code standards support assent-centered practice. Code 2.11 explicitly requires obtaining the client's assent to the extent possible. Code 2.01 requires effective treatment, which encompasses the learner's overall wellbeing and long-term engagement, not just skill acquisition rate.
Code 2.15 requires minimizing risk, and overriding assent withdrawal carries risks of emotional harm and damaged therapeutic relationships. Code 2.09 requires involving clients and stakeholders. For nonverbal learners, behavioral assent indicators are the primary mechanism for client involvement.
Together, these standards create a strong ethical foundation for treating learner communication with respect during sessions.
Document the behavioral indicators of assent withdrawal that were observed, the context in which they occurred, the practitioner's response, and the outcome. For example: 'During discrete trial instruction on tacting colors, learner turned away from materials and began crying. Practitioner paused instruction, offered a calming activity, and waited for signs of readiness.
After two minutes, learner re-engaged with modified task using preferred materials. Learner completed three trials with appropriate engagement.' This documentation supports clinical decision-making, provides data for pattern analysis, and demonstrates compliance with ethical standards related to assent.
Yes, although the specific indicators and strategies will vary. For very young children, assent is primarily communicated through approach and avoidance, comfort and distress signals. For older children with some verbal skills, verbal refusals and requests for breaks provide additional channels.
For adolescents and adults, assent conversations can become more explicit and collaborative. The principle remains the same across populations: the learner's behavioral communication about their experience deserves recognition and response. Practitioners must develop individualized assent profiles for each learner and train all team members to recognize and respond to the identified indicators.
RBTs need training in several areas: recognizing the specific assent withdrawal indicators for each learner on their caseload, understanding the graduated response protocol and when to apply each level of response, practicing connection strategies such as offering comfort and modifying demands, collecting data on assent-related interactions, and knowing when to seek guidance from the supervising BCBA. Training should include modeling, role-play, and feedback in the natural environment. It is essential that RBTs understand the rationale behind assent-centered practices so they can implement them with genuine responsiveness rather than as a rote protocol.
