One could argue many psychological problems arise from interpersonal or attachment issues, so I was eager to see an approach applied to this specific issue. I've read a few books by McKay, and enjoyed them, so I was surprised this one was directed specifically for therapists rather than the general public. I appreciated the scripts, exercises, and dialogues to illustrate the points rather than pure theory. McKay walks us through schemas, the related coping behaviors then ACT concepts such as creative hopelessness, mindfulness, and values clarification. Putting this all together, we develop value-based action, and teach clients how to develop a different relationship with their thoughts and emotions. I also enjoyed the appendices which include a schema assessment and a detailed ACT group plan. If you're new to ACT, this isn't the book to learn the foundations, rather assumes some knowledge of the approach. Nonetheless, I think ACT (with its focus on intentions and values) is a great way to blend behavioral orientations like CBT and DBT with more psychodynamic and existential therapies. Overall, Acceptance and Commitment Therapy for Interpersonal Problems is a brief, yet substantial guide for putting ACT in practice.
