Acceptance and commitment therapy: An experiential approach to behavior change. New York: Guilford Press. , Hayes, S. , & Walser, R. (2007). Learning ACT. Oakland, CA: New Harbinger. Conclusion ACT is part of a larger set of procedures, many of which have been shown to be relevant to substance abuse, including dialectical behavior therapy, functional analytic psychotherapy, mindfulness-based cognitive therapy, and mindfulness-based relapse prevention. No one factor unites these new methods, but all have ventured into areas traditionally reserved for the less empirical wings of clinical intervention and analysis, emphasizing such issues as acceptance, mindfulness, cognitive defusion, dialectics, values, spirituality, and relationship.

Representatives from agencies such as Join Together were recruited to write the entries on their organizations. The executive director of Faces and Voices of Recovery submitted several entries on recovery topics. Individuals with expertise in a specific topic were identified by editorial board members, by other contributors, or through our own contacts. While these experts did not always accept our invitation, they would usually recommend someone else with expertise in the topic. Potential contributors with faculty appointments at colleges and universities were assumed to be qualified to be authors.

In the copyediting stage, we were very fortunate to work with an extremely thorough, efficient, and responsive team: Tracy Buyan, production editor, and Colleen Brennan and Renee Willers, copy editors. We especially want to thank Yvette Pollastrini, our developmental editor. Yvette read all the entries and corresponded with us about numerous issues regarding format, content, and authors. She was consistently professional and efficient and had a major role in the timely completion of this encyclopedia.
