Goal Focused Positive Psychotherapy presents the first comprehensive positive psychology psychotherapy model that optimizes well-being and thereby diminishes psychological distress. The theory of change is the Broaden-and-Build Theory of positive emotions. The therapeutic process promotes client strengths, hope, positive emotions, and goals. The book provides the foundational premises, empirical support, theory, therapeutic techniques and interventions, a training model, case examples, and future directions. A three-year study is presented that reveals that Goal Focused Positive Psychotherapy (GFPP) was as effective as cognitive-behavioral therapy and short-term psychodynamic therapies, which fits the meta-analyses of therapy outcome studies that no bona fide psychotherapy achieves superior outcome. However, GFPP was significantly more attractive to the clients. Descriptions are provided of the Broaden-and-Build Theory, therapy goals based upon clients’ values and personal meaning (i.e., approach goals and intrinsic goals), identification and use of clients’ personal strengths (including client culture), centrality of hope and hope theory, the implicit theory of personal change or the growth mindset, and finally Self-Determination Theory. The techniques and interventions of GFPP as well as the importance of the therapist’s intentions during therapy are presented. GFPP focuses upon the client and relationship while not viewing psychotherapy as a set of potent scripted treatments that acts upon the client. Goal Focused Positive Supervision is presented as a new model that supports the supervisee’s strength-based self-definition rather than a pathological one or deficit orientation. Training that includes the experiential learning of GFPP principles is underscored.
