This report summarizes the research conducted under a project that began data collection among juvenile offenders in California in 1964 and 1965, gathered 20-year followup data during 1984 and 1985, and focused on examining the criminal career patterns of violent offenders.
Abstract
The research had four major objectives: (1) to assess the validity and usefulness of the data, (2) to examine criminal career patterns, (3) to apply event history analysis to the data, and (4) to begin collaborative research with leading researchers from various disciplines. Data coding and data entry for the long-term followup took place during 1987 and 1988. The study includes 4,146 individuals; arrest records are available for 3,652 individuals. These individuals were arrested 54,176 times. Violence was involved in 10,374 arrests. A total of 25,559 arrests were for offenses that endangered others such as drunk driving or burglary. The participants were grouped into four basic lifestyle categories based on the California Psychological Inventory developed by Harrison Gough. Joint research has also been conducted with Robert Barnhill to apply advanced data visualization techniques to the data. Several additional collaborative efforts are planned.
