In this second edition of Trance and Treatment, the Spiegels, drawing on their combined clinical experiences and on relevant research literature, have revisited and updated their integrative framework for understanding hypnosis. They continue to stress the importance of individual differences in hypnotic responsiveness as assessed through their well-known Hypnotic Induction Profile. In numerous and remarkably wide-ranging clinical examples they illustrate their reliance on hypnotic ritual as the transactional context for personological and diagnostic assessments and for accordingly tailored interventions. Trance and Treatment is a richly documented exposition of today's arguably most encompassing and challenging trance-based model of hypnosis and hypnotic intervention.

Trance and Treatment was written as an introduction for someone new to the subject of hypnosis, but also includes material in sufficient depth so that therapists with wide experience in the field can acquire new perspectives. Our approach differs from the current clinical literature in emphasising the importance of performing a systematic assessment of hypnotisability; the method is described in detail along with data relating performance on the Hypnotic Induction Profile to personality style, psychopathology, and treatment outcome.
