This comparison draws in part from “Invited Speaker: Collaboration through the Lens of Adult Services” by Lauren Ross, M.S. CCC-SLP, 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 →Two dominant service delivery structures exist for adults with IDD receiving both behavior support and communication services: the Therapeutic Consultation model, which requires joint assessment and co-developed plans, and parallel independent practice, where each discipline works autonomously and coordinates informally. Pichardo et al. (2026) found that caregiver-reported treatment effect accuracy depends heavily on the clarity and consistency of implementation instructions—a finding that structurally favors coordinated models over siloed ones. Choosing between these frameworks depends on your agency's staffing, the clinical complexity of your caseload, and the extent to which your funding sources require or incentivize integrated service delivery documentation.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Assessment Process | TC Model: Joint functional assessment; SLP and BCBA participate simultaneously; communication function identified before behavior plan is written | Parallel Practice: Each discipline completes independent assessment; communication function may or may not be shared with behavior analyst before plan development |
| Treatment Planning | TC Model: Co-developed behavior support plan with explicit SLP-approved communicative replacement behaviors; shared documentation | Parallel Practice: Separate treatment plans; replacement behavior form not necessarily confirmed by SLP; potential for contradictory recommendations |
| Implementation Fidelity | TC Model: Support staff receive unified training from both disciplines; role conflicts pre-resolved through shared protocol | Parallel Practice: Support staff may receive conflicting instructions; fidelity monitoring conducted by each discipline separately |
| Funding & Authorization | TC Model: Requires joint authorization or waiver flexibility; some payers resist funding two disciplines for the same session | Parallel Practice: Each discipline bills independently; simpler authorization; but risk of misaligned service intensity |
| Ethical Risk | TC Model: Lower risk of scope-of-practice violations; explicit role boundaries reduce dual-relationship concerns | Parallel Practice: Higher risk that BCBA implements communication procedures outside competence without SLP oversight |
| Documentation Burden | TC Model: Higher upfront documentation; joint meeting notes, co-signed plans; more time-intensive but clearer legal record | Parallel Practice: Lower documentation burden per discipline; but harder to demonstrate coordinated care to regulators or payers |

Use this framework when approaching invited speaker: collaboration through the lens of adult services 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.
