With an endorsement by Christopher Peterson of the University of Michigan and Forewards by two recognized authorities in positive psychology and cognitive therapy—Ed Diener and David A. Clark—this new approach to positive psychology tells clinicians how to bring positive psychology techniques to clinical practice.

Quality of Life Therapy also shows clinicians how to expand their practice to "pure" positive psychology cases and professional groups who do not suffer from clinical or DSM disorders but who nevertheless want to be happier and more successful in life. The book includes 44 positive psychology growth exercises on CD-Rom, and 148 happiness prescriptions based on the latest research for use in all areas of life that clients may care about, including life Goals-and-Values, Spiritual Life, Self-Esteem, Health, Relationships, Work, Play, Helping, Learning, Creativity, Money, Surroundings—Home, Neighborhood, Community—and relapse prevention.

The book includes a primer (or quick review of) in Beck's latest approach to cognitive therapy along with instructions for integrating it with positive psychology. Quality of Life Therapy has been evaluated as successful in two separate clinical trials conducted at different laboratories with clinically depressed and lung transplantation patients. For example, see: Rodrigue, J. R., Baz, M.A., Widows, M.R., & Ehlers, S.L. (2005). "A Randomized Evaluation of Quality of Life Therapy with Patients Awaiting Lung Transplantation".
