A previous research project had developed a classification system that contained 10 subtypes. However, this system had significant reliability problems. The present research used a rational/clinical and empirical/analytical methodology to revise this MTC:R2 system. The result was the MTC:R3 classification system which contained four general rapist types encompassing nine rapist subtypes. These were (1) Opportunistic with two social competence subtypes; (2) Pervasively Angry or Sexual with four subtypes related to sadism and social competence; and (3) Vindictive with two social competence subtypes. The system was applied to 300 cases at the Massachusetts Treatment Center. The results showed high reliability and reasonable concurrent validities.
