Those who are interested in the evolution of Cognitive Therapy over time may be interested in Isabel Caro's article The Way We Were, the Way We Are:Cultural Evolution of Cognitive Therapy which appeared in the Summer II, 2004 edition of the Behavior Therapist . It takes an interesting look at paralells between changes in Western culture and the evolution of Cognitive Therapy. [Please note that Beck and I would argue vigorously against the assertion that CT is a "rationalist" approach. We see CT as a phenomenological approach (see Pretzer & Beck, 1996)]

Personally, I'm not convinced that it makes sense to think of MBSR, DBT, ACT, and MBCT as a "third wave." The four approaches were developed independently at different points in time and have very substantial differences in their conceptual frameworks, theoretical constructs, and therapeutic interventions. Each of the four makes some valuable points but I'm not convinced that they embody a coherent "wave."
