However, most sexual offending typologies focus on an individual’s most recent sexual offense. We compare data from Belgian and Dutch national conviction cohorts and use latent class analysis to distinguish groups of individuals based on their history of sexual and nonsexual offenses, considering continuity and variety. The resulting classification is compared between individuals convicted of sexual offenses and individuals convicted of nonsexual offenses. Results show that four latent classes can be distinguished based on continuity and variety in criminal histories of individuals convicted of sexual offenses, and that some of these classes resemble those distinguished among individuals convicted of nonsexual offenses. We find limited overlap between these latent classes and typologies based solely on the index offense. Results show marked similarities across countries. These results challenge theories of sexual offending to incorporate patterns of nonsexual offending.
