Disciplinary Centrism vs. Interprofessional Practice: Two Models for Behavior Analysts

In This Guide

Side-by-Side Comparison
Clinical Decision Framework
Key Takeaways

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 stronger together: elevating outcomes through interprofessional collaboration, 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.

Side-by-Side Comparison

Factor	Evidence-Based Approach	Traditional Approach
Assessment comprehensiveness	Disciplinary Centrism: Thorough behavioral assessment (functional analysis, preference assessment, skill assessment) but may miss non-behavioral factors contributing to the clinical picture	Interprofessional Practice: Behavioral assessment integrated with sensory, communicative, medical, educational, and psychosocial assessment for a more complete understanding
Treatment planning	Disciplinary Centrism: Intervention designed from behavioral principles alone; may be technically sound but clinically incomplete	Interprofessional Practice: Co-designed intervention that addresses behavioral, sensory, communicative, and contextual factors simultaneously
Communication with team members	Disciplinary Centrism: Heavy use of behavioral jargon; reports and recommendations may be inaccessible to other professionals and families	Interprofessional Practice: Concepts translated into shared language; technical precision maintained in documentation but communication adapted to audience
Response to conflicting recommendations	Disciplinary Centrism: Other disciplines' recommendations evaluated against behavioral standards; dismissed if they do not meet behavioral evidentiary criteria	Interprofessional Practice: Conflicting recommendations explored as clinical information; differences investigated as potential indicators of complexity rather than incompetence
Client and family experience	Disciplinary Centrism: Family may receive conflicting guidance from uncoordinated providers and bear the burden of integration	Interprofessional Practice: Family receives consistent, coordinated guidance and experiences professionals working as a unified team
Professional development	Disciplinary Centrism: Deepening expertise within behavior analysis; limited exposure to other perspectives	Interprofessional Practice: Expanding expertise across disciplines; developing communication and collaboration skills alongside clinical skills

Clinical Decision Framework

Use this framework when approaching stronger together: elevating outcomes through interprofessional collaboration in your practice:

Step 1: Is intervention warranted?

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

Step 2: Have you conducted an individualized assessment?

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

Step 3: Is the individual/caregiver involved in decision-making?

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

Step 4: Verify your approach

✓ Is your intervention matched to the assessed function?
✓ Are you using the least restrictive effective approach?
✓ Is assent being monitored throughout?
✓ Do you have a data collection plan?
✓ Is there a plan for generalization and maintenance?

Key Takeaways

Individualization is non-negotiable. The best approach for one individual may not be appropriate for another, even with the same topography.
Assessment drives intervention. Function-based approaches consistently outperform topography-based ones in the literature.
Ethics are active, not passive. Ethical practice requires ongoing analysis, not just initial compliance.
Document everything. Both the decision to intervene and the decision not to intervene require documentation and justification.
Stay current. The evidence base in this area is evolving. What was standard practice five years ago may not reflect current best practices.
