This comparison draws in part from “Client Assent” by Tessa Divine, MS, BCBA, LBA (BehaviorLive), and extends it with peer-reviewed research from our library of 27,900+ ABA research articles. The decision framework, BACB ethics code references, and cross-links below are synthesized by Behaviorist Book Club.
View the original presentation →Applied behavior analysis has historically operated along a spectrum from compliance-based to assent-based approaches. Compliance-based practice prioritizes the client's completion of therapist-directed tasks as the primary indicator of session success, while assent-based practice centers the client's ongoing willingness to participate as a foundational condition of ethical treatment. Understanding the distinctions between these approaches helps practitioners evaluate their own practice and make deliberate choices about how they structure therapeutic interactions. This comparison is not meant to suggest that structure and expectations have no place in ABA but rather to clarify the ethical and clinical differences between approaches that prioritize client agency and those that prioritize task completion.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Primary Measure of Session Success | Compliance-Based: Percentage of demands completed, trials run, or tasks finished within the session | Assent-Based: Client engagement and willingness to participate alongside meaningful skill progress |
| Response to Client Refusal | Compliance-Based: Refusal is treated as non-compliance to be addressed through prompting, reinforcement contingencies, or continued demands | Assent-Based: Refusal is treated as communication to be honored, with modification of demands, breaks, or alternatives offered |
| Role of the Client | Compliance-Based: Passive recipient who follows therapist-directed activities in a predetermined sequence | Assent-Based: Active participant whose preferences shape session content, pacing, and structure |
| Therapeutic Relationship | Compliance-Based: Hierarchical relationship where the therapist directs and the client follows | Assent-Based: Collaborative relationship built on trust where the client's autonomy is respected |
| Long-Term Behavioral Outcomes | Compliance-Based: Risk of prompt dependency, learned helplessness, and behavior maintained only by external contingencies | Assent-Based: Greater intrinsic motivation, self-determination, and generalization of skills across settings |
| Alignment with Ethics Code | Compliance-Based: May conflict with Code 2.14 (least restrictive), Code 2.15 (minimizing risk), and Code 1.10 (awareness of biases) | Assent-Based: Directly supports Code 2.01 (effective treatment), Code 2.14, and the dignity-focused principles throughout the Code |
| Staff Training Emphasis | Compliance-Based: Training focuses on maintaining instructional control and reinforcing compliance | Assent-Based: Training focuses on recognizing communication, offering choices, and responding to assent withdrawal |

Use this framework when approaching client assent in your practice:
Does the data support a need for intervention? Is there a meaningful impact on the individual's quality of life, safety, or access to reinforcement?
YES → Proceed to assessment NO → Document reasoning, monitor
A functional assessment should guide intervention selection. Avoid defaulting to standard protocols without individual analysis. Consider environmental variables, setting events, and private events.
YES → Select evidence-based approach matched to function NO → Complete assessment first
Goals should be co-developed. Assent and informed consent are ethical requirements. The individual's preferences and values matter in selecting both goals and methods.
YES → Proceed with collaborative plan NO → Engage in shared decision-making
This course covers the clinical and ethical dimensions in detail with structured learning objectives and CEU credit.
