This comparison draws in part from “When Good Ethics Go Bad: Understanding Evidence Based Practice” (Do Better Collective), 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 →Protocol-based practice applies a standardized sequence of procedures to clients based on diagnosis or intake category. Individualized evidence-based practice begins with the specific client and selects and adapts procedures based on that client's assessment data, learning history, and response to treatment. Both approaches claim to be evidence-based, but the evidence-based practice model — as described in the BACB Ethics Code and in the broader health professions literature — clearly requires individualization. The comparison below examines how these two orientations differ in practice across dimensions that directly affect client outcomes and ethical compliance.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Starting point | Individual client assessment data and learning history | Diagnosis category or program model intake criteria |
| Procedure selection | Selected and adapted based on client's current repertoire and response to training | Selected from standardized protocol based on diagnostic category |
| Response to non-progress | Systematic barrier assessment followed by individualized procedure modification | Increase intensity or switch to next protocol step |
| Role of clinical expertise | Essential — expertise guides individualization and interpretation of client data | Reduced — protocol specifies decisions; clinician implements fidelity |
| Code 2.14 compliance | Built in — individualization includes ongoing evaluation and modification based on data | May be limited — protocol adherence can delay or prevent modification when indicated |
| Client values and preferences | Actively incorporated into goal selection and procedure design (Code 2.09) | May be secondarily considered after protocol requirements are met |

Use this framework when approaching when good ethics go bad: understanding evidence based practice 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.
