Robert Leahy, Dennis Tirch, and Lisa Napolitano are veterans in the field of therapy. Together they draw from the realms of cognitive therapy, cognitive-behavioral therapy, mindfulness practice, and compassion-based therapy. Their collective effort, Emotion Regulation in Psychotherapy, is a helpful manual for a wide variety of therapists in a wide variety of fields. Techniques to treat patients through emotion regulation can be applied to all levels of therapeutic interventions, from crisis stabilization to inpatient treatment to outpatient treatment maintenance. Any level or type of provider could use these techniques; they are equally useful to psychologists, social workers, physicians, nurse practitioners, and other health care providers.
