Commentary on Hofmann and Hayes: The water looks inviting, but how and when do we jump in?

Hofmann and Hayes (this issue) shine a light on our field's lack of progress in reducing the prevalence and burden of mental illness, and suggest that a paradigm shift is needed to make more rapid progress. They argue that empirically-supported processes of change should guide treatment planning, rather than treatment packages. This approach should allow for greater personalization of treatment, more iterative treatment planning, and increase the scalability of our intervention delivery models. In this commentary, I discuss some of the difficult questions that will arise when trying to make the shift from treatment packages to process-based therapy, and highlight some steps that we can take now to facilitate the shift.
