He implemented FFT in the Netherlands and in Ireland. He is co-author of the FFT clinical manual (Sexton & Alexander 2004), author/co-author of the most recent theoretical chapters on FFT and designed the most recent training and implementation procedures for moving FFT into community based clinical settings.

His recent publication in the Journal of Family Psychology (Sexton & Turner, 2010) is the first FFT outcome study in more than 20 years. His most recent book Functional Family Therapy in Clinical Practice is the first book on FFT in over 30 years. In addition, his scientific work is funded by the National Institute of Mental Health and the National Institute of Drug Abuse. His most recent funded project investigates the use of computer technology in enhancing treatment outcomes of FFT in clinical settings.
