Researchers and law enforcement officials normally refer to the offenders' collective pattern of crime-related behaviors as those particular individuals' MO (modus operandi). The MO of the sexual offender is particularly important when determining the proper treatment from prison into the Swedish community during the years of 1993 to 1997. The study analyzed each offender's MO in terms of victim choice, offense nature, an severity as compared to other registered offenses. The study found that the stability of MO was high, especially with relation to victim choice. Researchers also found it important to note that the stability of registered sexual offense MO may not generalize the self-reported sexual offense behavior. The results of this study support further elaboration of sexual offender recidivism risk in clinical practice through pointing out potential sexual recidivism characteristics and important risk situations.
