Perhaps you’re thinking of Emotionally Focused Therapy, which is indeed a very effective form of couple and family therapy based on both process and outcome research, which has publications in most major family therapy journals and a large evidence base for its success rate, including with PTSD. It is indeed a fantastic, evidence-based approach, has an extremely high quality certification program, and I can personally testify to how effective it is with distressed couples, as a 17-year veteran of family therapy. The results it’s getting with sexual abuse survivors, traumatized vets, and public safety employees (firefighters etc.) who have traumatic stress are phenomenal.
However, they are referring to Emotional Freedom Technique, a derivative of Thought Field Therapy, both of which are unmitigated woo-type bullshittery and which are all too common in my beloved Bay Area. And which has, apparently, an army of highly motivated astroturfers, meaning that it comes up much higher than the actual well-tested and researched EFT approach in a Google search.
