This book provides a comprehensive resource guide for Marriage and Family Therapists (MFTs), Approved Supervisors, and Supervisors-in-training. It looks at theories used in American Association for Marriage and Family Therapy (AAMFT) supervision and also at other important aspects of supervision. The book is divided into four parts. Part I focuses on supervision across time. The history and today’s trends have laid the foundation for the development of the process of supervision and show that the supervision process has to be flexible as the field changes and must be reflective of the field as it currently exists. The second part focuses on the nuts and bolts of supervision. Basic concepts such as how to get started in supervision, the various forms of supervision used by AAMFT Approved Supervisors, and the developmental readiness of the supervisor-in-training are dealt with here. Clinicians and researchers in the field are looking more critically, through empirical and other research, at how culture, race, and gender should be considered and addressed in the process of supervision. Part III focuses on theory-specific supervision. Various chapters cover the training imparted in structural therapy, strategic therapy, multigenerational family therapy, cognitive behavioral therapy, post-modern supervisor, systemic cognitive-developmental therapy, contextual therapy, the narrative therapy and others. The emotionally focused therapy supervision model is the first known empirically derived model of supervision in the field of couple and family therapy. Part IV deals with population-specific supervision. One chapter has been devoted to medical family therapy supervision and another to trauma supervision.
