Relational Behavior and ACT: A Dynamic Relationship
Track moment-to-moment changes in client word-word and word-feeling links to steer ACT moves in real time.
01Research in Context
What this study did
Belisle et al. (2022) wrote a how-to paper for clinicians.
They asked: What happens if we treat "relational framing" as a moving target inside ACT sessions?
The authors mapped each ACT hexaflex process to live shifts in client word-word and word-emotion links.
What they found
The paper does not give new data.
It gives a game plan: watch how client relations form, bend, and break moment-to-moment, then use that flow to guide mindfulness, values, and defusion moves.
How this fits with other research
Salzinger (2003) first re-defined verbal behavior as relational framing; Belisle picks up that baton and runs it into ACT rooms.
Barnes-Holmes et al. (2018) showed clinicians how to drill from big client stories down to tiny RFT units—Belisle extends that drill-up idea into real-time ACT coaching.
Barnes-Holmes et al. (2026) will re-write RFT itself using field-based terms; Belisle’s dynamic lens sets the stage for that next jump.
Why it matters
You no longer need to wait for post-session tests to see if "cognitive fusion" dropped. Instead, track live shifts in client language relations—like when "failure" stops pairing with "me"—and pivot your intervention on the spot. It turns ACT into a sensor-guided sport instead of a season-long guess.

03Original abstract
Acceptance and commitment therapy (ACT) and its counterpart, relational frame theory (RFT), represent emerging areas of research and professional interest for behavior analysts. We extend traditional RFT approaches by emphasizing relational framing as a dynamic pattern of behavior with implications for ACT-based strategies implemented by behavior analysts in practice and in research. We borrow from emerging approaches within affective dynamics, relational density theory, and the hyper-dimensional multilevel model to develop some immediate considerations for practitioners. We then extend an approach grounded in relational dynamics to the six core processes of the ACT hexaflex not only to influence negative affective patterns of relational behavior but also to promote greater psychological flexibility and well-being. Finally, we turn this account inward to discuss our own rigidity as a field and the necessity to engage more flexibly with our own science, ultimately to improve the lives of clients whom we serve.
