ACT and RFT in Relationships: Helping Clients Deepen Intimacy and Maintain Healthy Commitments Using Acceptance and Commitment Therapy and Relational Frame Theory by Dahl PhD, JoAnne, Stewart PhD, Ian, Martell PhD, Christopher (2014) Paperback
I really like the use of RFT in here just enough to give the average reader an idea of what's behind the clinical applications. As an ACT practitioner I might have liked a little more of that technicality and more discussion on handling various types of more engrained couples problems.
