Can changes in life circumstances, such as being employed, living with a wife or girlfriend, or modifying alcohol or drug use, alter the crime patterns of convicted adult male felons? Adult Patterns of Criminal Behavior presents the findings of a study conducted for the National Institute of Justice, which sought to understand the relationship between adult patterns of criminal behavior and relatively short-term changes in work, family, and other social situations. The researchers conducted indepth interviews with convicted felons and analyzed month-to-month changes in offending and life circumstances to understand change in adult criminal behavior. The results strongly demonstrate that social events during adulthood are related to crime.
