By Matt Harrington, BCBA · Behaviorist Book Club · Clinical decision guide
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 **out of the vault** invited presentation - the scientist practitioner model: conceptualizing the relationship between research and practice in applied behavior analysis, 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 |
|---|---|---|
| Relationship to research production | Scientist-practitioner: Expected to contribute to the knowledge base through systematic data collection, n=1 research, conference presentations, and formal or informal research collaboration; practice is viewed as a source of scientific questions | Practitioner-scholar: Primary role is to consume, evaluate, and apply existing research rather than produce new knowledge; contribution to the knowledge base is through excellent implementation rather than empirical generation |
| Data collection and analysis orientation | Scientist-practitioner: Collects data with the rigor of a researcher—operational definitions, reliable measurement, graphed data reviewed systematically; identifies functional relationships between intervention and behavior change | Practitioner-scholar: Collects data to monitor progress and inform clinical decisions; less emphasis on experimental control and causal inference; may rely more on clinical judgment to interpret ambiguous data patterns |
| Engagement with primary literature | Scientist-practitioner: Regular engagement with primary research articles in JABA and related journals; maintains current knowledge of methodology and emerging findings; critically evaluates research quality | Practitioner-scholar: Primarily engages with research through summaries, guidelines, treatment manuals, and CEU content; less emphasis on methodological evaluation; relies on professional consensus to identify evidence-based practice |
| Response to intervention failure | Scientist-practitioner: Treats intervention failure as a scientific question—generates alternative hypotheses, reviews relevant literature, designs systematic probes to test hypotheses before changing approach | Practitioner-scholar: Draws on clinical experience and consultation to identify alternative approaches; may rely on expert guidance or established protocol modifications rather than individually designed experimental probes |
| Training and professional development focus | Scientist-practitioner: Seeks training that builds methodological skills—single-subject design, measurement, behavioral assessment—alongside clinical competencies; values research mentorship | Practitioner-scholar: Prioritizes clinical skill development, supervisory competence, and applied specialization; values practical training experiences and expert clinical mentorship over methodological training |
| Contribution to field advancement | Scientist-practitioner: Contributes through systematic observation, data sharing, and research participation; the aggregated practice-based data of scientist-practitioners collectively advance the field's knowledge base | Practitioner-scholar: Contributes through excellent service delivery, training of new practitioners, community engagement, and dissemination of evidence-based practices to families and systems |

Use this framework when approaching **out of the vault** invited presentation - the scientist practitioner model: conceptualizing the relationship between research and practice in applied behavior analysis 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.
