The USC Program and Academic Foundation
LOS ANGELES, CALIFORNIA – Dr. Jonathan Tarbox holds a Ph.D. in behavior analysis and a BCBA-D credential, and serves as the Cofounder and Program Director of the Master of Science in Applied Behavior Analysis at the University of Southern California’s Dornsife College of Letters, Arts and Sciences. The USC program is among the most visible university-based ABA training programs in the country, producing graduates who enter clinical, research, and leadership roles across the autism services industry.
Tarbox’s academic output is extensive. He has published five books on applied behavior analysis and autism treatment, more than 90 peer-reviewed articles, and numerous book chapters. His publication record spans clinical intervention research, conceptual analysis of behavior analytic principles, and applied work on teaching complex skills to individuals with autism spectrum disorder.
Beyond his own research, Tarbox serves as Series Editor of the Elsevier book series Critical Specialties in Treating Autism and Other Behavioral Challenges — a role that gives him influence over the pipeline of academic texts reaching behavior analysts in training. The series covers foundational and emerging topics in ABA, from early intervention methodologies to advanced clinical applications.
Tarbox occupies a position at the intersection of academic credentialing, journal editorship, and clinical innovation that few figures in ABA can match. His work shapes not only what practitioners read but how the next generation of BCBAs is trained.
Editor-in-Chief: Behavior Analysis in Practice
Tarbox served as Editor-in-Chief of Behavior Analysis in Practice, the applied journal published by the Association for Behavior Analysis International (ABAI). The journal occupies a specific and important niche in ABA’s publishing ecosystem: it bridges the gap between the Journal of Applied Behavior Analysis (JABA) — the field’s flagship empirical journal — and the day-to-day clinical decisions that practitioners face.
As Editor-in-Chief, Tarbox shaped the journal’s editorial direction during a period of significant growth in the ABA profession. The number of BCBAs in the United States has grown from approximately 25,000 in 2015 to more than 60,000 by 2025, and Behavior Analysis in Practice has become an increasingly important venue for translating research findings into practitioner-accessible guidance.
His editorial tenure coincided with a period of intensifying debate within the field about scope of practice, the role of caregiver training, and the relationship between ABA and other therapeutic modalities — debates that the journal both reflected and helped to shape through its selection and framing of published work.
Bringing ACT Into ABA
The element of Tarbox’s career that has generated the most discussion — and, in some quarters, the most debate — is his work integrating Acceptance and Commitment Training (ACT) into mainstream ABA practice. ACT, rooted in relational frame theory and the broader tradition of contextual behavioral science, emphasizes psychological flexibility, values-based action, and mindfulness-informed techniques.
In a 2020 article published in Behavior Analysis in Practice, Tarbox and colleagues presented a detailed argument for why ACT falls within the scope of practice for behavior analysts. The paper, which has been cited more than 130 times, provided conceptual functional analyses of core ACT processes and offered practical guidelines for clinicians seeking to incorporate these techniques into their existing behavioral repertoire.
Key argument: ACT is not a departure from behavior analysis but rather an extension of it — grounded in the same philosophical assumptions (functional contextualism) and the same basic science (relational frame theory) that underlie other behavior analytic interventions.
This position has attracted both support and criticism. Supporters view ACT integration as a natural evolution of ABA, expanding the field’s tools for addressing the verbal and emotional dimensions of behavior that traditional contingency management approaches often leave unaddressed. Critics argue that certain ACT techniques — particularly those involving metaphor, mindfulness exercises, and values clarification — stretch the boundaries of what behavior analysts are trained and credentialed to do.
The ACT-in-ABA debate is, at its core, a debate about the identity of behavior analysis itself: whether the field’s future lies in expanding its conceptual and practical boundaries or in maintaining sharper distinctions between behavior analysis and adjacent therapeutic traditions.
Tarbox has also co-authored a book on the topic: ACT and Applied Behavior Analysis: A Practical Guide to Ensuring Better Behavior Outcomes Using Acceptance and Commitment Training, published by New Harbinger Publications. The book targets practicing behavior analysts and provides step-by-step guidance for implementing ACT-informed strategies within an ABA framework.
The LinkedIn Presence and Conference Circuit
Unlike many ABA influencers who build their platforms on Instagram or TikTok, Tarbox’s primary social media presence is on LinkedIn — a platform that skews toward professional and academic networking. His LinkedIn posts frequently address topics at the intersection of behavior analysis, organizational behavior management, and clinical philosophy, reaching an audience of BCBAs, program directors, university faculty, and practice owners.
Tarbox is also a regular presence on the ABA conference circuit, including presentations at the annual ABAI convention and regional conferences. His talks often center on ACT integration, the future of behavior analytic training, and the philosophical foundations of the field. He has also delivered continuing education workshops through multiple platforms, including Behavior University and university-affiliated training programs.
His combination of academic affiliation, journal editorship, book authorship, and active social media engagement has made Tarbox one of the most visible academic voices in a field where clinical practitioners and practice owners have traditionally dominated the influencer landscape.
What Tarbox’s Influence Means for the Field
Tarbox represents a specific and increasingly important category of ABA influencer: the academic-practitioner whose influence flows through institutional channels — university programs, journal editorial boards, book series — as much as through direct-to-audience content. His reach is not measured in follower counts but in the number of graduate students trained through the USC program, the articles published under his editorial direction, and the clinicians who have adopted ACT-informed approaches based on his published work.
For the ABA industry, Tarbox’s prominence signals that the field’s intellectual center of gravity is not limited to traditional operant methodology. The growing interest in contextual behavioral science, relational frame theory, and ACT represents a broadening of the behavior analytic toolkit that has direct implications for clinical practice, insurance coverage of non-traditional behavioral interventions, and the training curricula of university ABA programs nationwide.
