This study aimed to describe the process of Japanese sexual offenders in detail. Referring to the grounded theory model, this study qualitatively analyzed the following data from 33 probationers and parolees: (a) the narrative of the offenders, and (b) the content of free-writing sections of worksheets they were instructed to fill in during the special treatment program at probation offices. The resulting model consisted of 15 categories including key precursors of sexual offending such as problems in the offender’s life and cognitive factors. Furthermore, this study revealed that many participants experienced serious and/or multiple problems. Additionally, results indicated that these problems provoked a cycle of coping with the issues, an unstable psychological state, and their perception of said problems, which led to the cognitive factors. The clinical implications of the model for assessment and treatment of sexual offenders were then discussed.
