This comparison draws in part from “Understanding Models of Disability: Embracing Neurodiversity in Disability Services Through a Behavior Science Lens” by Brian Middleton, BCBA (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 →One of the most consequential decisions a behavior analyst makes is not just what intervention to use, but how to approach the clinical question in the first place. For understanding models of disability: embracing neurodiversity in disability services through a behavior science lens, the difference between an evidence-based, individualized approach and a traditional, protocol-driven one can significantly impact outcomes.
This guide lays out the key factors side by side to support your clinical decision-making.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Source of Disability | Medical Model: Disability resides within the individual as a deficit or pathological condition | Social Model: Disability is created by the interaction between individual differences and environmental barriers |
| Goal of Intervention | Medical Model: Fix, remediate, or normalize the individual's functioning to approximate typical development | Social Model: Remove barriers, increase accessibility, and create environments where the individual can participate authentically |
| View of Stimming | Medical Model: Stereotypic behavior that should be reduced or replaced with more typical alternatives | Social Model: Self-regulatory behavior that serves a function and should be accommodated unless it causes genuine harm |
| Social Skills Approach | Medical Model: Train the individual to perform neurotypical social behavior including eye contact and typical conversational patterns | Social Model: Support the individual's genuine social goals while educating communication partners about neurodivergent communication styles |
| Assessment Focus | Medical Model: Identifies deficits, delays, and areas of impairment within the individual | Social Model: Identifies environmental barriers, inaccessible conditions, and opportunities for accommodation alongside individual strengths and preferences |
| Outcome Measurement | Medical Model: Measures change in the individual's behavior toward normative standards | Social Model: Measures environmental accessibility, client satisfaction, quality of life, and meaningful participation in chosen activities |
The ABA Clubhouse has 60+ on-demand CEUs including ethics, supervision, and clinical topics like this one. Plus a new live CEU every Wednesday.
Use this framework when approaching understanding models of disability: embracing neurodiversity in disability services through a behavior science lens 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.
