Reflections on Six Decades of Research

A brief autobiographical history is presented covering my 57-year career as a criminologist. I begin with my early childhood experiences, growing up during World War II, my undergraduate and graduate school experiences, and my early career years at San Diego State University and the University of Colorado, Boulder. I then discuss two of the major themes in my research developed during these early career years: self-report measures of delinquent behavior and the Integrated Theory of delinquency. My later career years are described, and the third major theme of my work, the identification and promotion of effective delinquency prevention programs, is discussed.
