This is the first book devoted to the epidemiology of sleep and presents the most systematic, detailed accounting to date of how people sleep.

"This is an interesting compilation of the authors' research data together with a literature review on self-reported insomnia through 2002....it fills an important niche in the epidemiological study of sleep -- these rich survey questionnaire data should satisfy the appetite of clinicians and researchers alike, and point the way toward further work in understanding sleep and refining methods for studying it."

—Doody's Notes

"...the authors thoughtfully explain their choice of measures, methods, and the rationale for data analyses. The book is logically well organized....is a significant contribution to the field of sleep research and a useful reference for clinicians."

—American Journal of Clinical Hypnosis

"I am excited by these data and by this whole project. There is no doubt that this book will be sought after by the scientific and clinical community who work with people with sleep disorders."
—Colin A. Espie

"My impression is that this book will likely grace the bookshelves of everyone that seeks to behaviorally treat patients with sleep disorders."
