The Society for Life History Research in Psychopathology is a group of investigators from many disciplines who share an interest in studying the longitudinal aspects of psychiat ric disorder. Sociologists, psychologists, statisticians, psychiatrists, epidemiologists, and others each bring to the study of life history the expertise and vantage point arising from his or her unique training and experience. This volume, the fifth in a series, is devoted to explor ing the methods used to contribute to the understanding of the complex unfolding of a human life as it avoids, copes with, or succumbs to psychiatric disorder. We hope that by describing these methods, their current status, advantages, and short comings, this volume can serve as a guidepost to all who are involved in our field to help understand it further and to generate solutions for the many crucial problems we face.
