Sex offender typologies have been developed in an effort to better understand the heterogeneity of sexual offending as well as offenders’ varied risk and therapeutic needs. Perhaps the most well-known and validated child molester typology is the Massachusetts Treatment Center: Child Molester Typology–Version 3 (MTC:CM3). However, this typology was developed and validated using primarily White sex offenders. The current study aimed to replicate this typology in an ethno-racially diverse sample of incarcerated White, Black, and Latino child molesters (N = 499). Overall, we found that the MTC:CM3 was applicable to non-White child molesters but that there were differences in the proportion of offenders of different ethno-racial groups in Axis I type classifications. We found no differences in Axis II type classifications. Specifically, Black offenders were more often classified as socially incompetent and sexually attracted to adults compared with White and Latino offenders. Whereas White offenders were more often classified as socially incompetent and sexually fixated on children when compared with Black offenders, Latino offenders were more often classified as high in social competence and sexually attracted to adults than Black offenders. On Axis II, the majority of all three subsamples were classified as not having sexual contact with children beyond the offense, unlikely to inflict physical harm on victims, and as not having sadistic interests. Addressing these typological characteristics in the development and implementation of prevention and treatment efforts might increase the responsiveness of specific sex offender populations.
