This accessible book presents time- and cost-effective strategies for helping clients break free of dysregulated behaviors--such as substance abuse, binge eating, compulsive spending, and aggression--and build more fulfilling, meaningful lives. Mindfulness and modification therapy (MMT) integrates mindfulness practices with elements of motivational interviewing, dialectical behavior therapy, acceptance and commitment therapy, and other evidence-based approaches. It can be used as a stand-alone treatment or a precursor to more intensive therapy. In a convenient large-size format, the book includes session-by-session implementation guidelines, case examples, practical tips, guided mindfulness practices, and 81 reproducible client handouts and therapist sheets. Purchasers get access to a companion website where they can download audio recordings of the guided practices, narrated by the author, plus all of the reproducible materials.
