Many have wondered if there is a key ingredient to living a full and happy life. For decades now, scientists and psychologists alike have been studying the strengths and virtues that enable individuals and communities to thrive. The positive psychology movement was founded on the belief that people want to lead meaningful and fulfilling lives, to cultivate what is best within themselves, and to enhance their experiences of love, work, and play. At the same time, acceptance and commitment therapy (ACT)—a mindfulness-based, values-oriented behavioral therapy that has many parallels to Buddhism, yet is not religious in any way—has been focused on helping people achieve their greatest human potential. Created only years apart, ACT and positive psychology both promote human flourishing, and they often share overlapping themes and applications, particularly when it comes to setting goals, psychological strengths, mindfulness, and the clarification of what matters most—our values and our search for meaning in life. Despite these similarities, however, the two different therapeutic models are rarely discussed in relation to one another. What if unifying these theories could lead to faster, more profound and enduring improvements to the human condition? Edited by leading researchers in the field of positive psychology, Mindfulness, Acceptance, and Positive Psychology is the first professional book to successfully integrate key elements of ACT and positive psychology to promote healthy functioning in clients. By gaining an understanding of "the seven foundations of well-being," professionals will walk away with concrete, modernized strategies to use when working with clients. Throughout the book, the editors focus on how ACT, mindfulness therapies, and positive psychology can best be utilized by professionals in various settings, from prisons and Fortune 500 business organizations to parents and schools. With contributions by Steven C. Hayes, the founder of ACT, as well as other well-known authorities on ACT and positive psychology such as Robyn Walser, Kristin Neff, Dennis Tirch, Ian Stewart, Louise McHugh, Lance M. McCracken, Acacia Parks, Robert Biswas-Diener, and more, this book provides state-of-the-art research, theory, and applications of relevance to mental health professionals, scientists, advanced students, and people in the general public interested in either ACT or positive psychology.
