S Reid, Application of the MTC:R3 Typology

  1. 1. Application of the MTC:R3 Typology to New Zealand High-Risk Rapists: <br />A Pilot Study.<br />Sarah Reid<br />Dr Doug Boer<br />Dr Nick Wilson<br />
  2. 2. Background<br />Rapist heterogeneity<br />Across interpersonal, psychological, <br /> cognitive and behavioral domains is a common research finding (Langton & Marshall, 2001). <br />Classification systems<br />Offer an organizing structure.<br /> enable greater understanding of differentiating core characteristics and offence motivations. <br />
  3. 3. The Massachusetts Treatment Centre Rapist Typology<br />Figure 1: MTC:R3 Typology (Knight & Prentky, 1990).<br />
  4. 4. Sexually Motivated <br />Opportunistic<br />Impulsive, little planning.<br />Motivated by immediate sexual gratification.<br />Sexual Sadistic<br />Presence of sexual fantasies.<br />Fusion of sexual and aggressive drives.<br />Sexual Non-Sadistic <br />Enduring sexual preoccupation.<br />
  5. 5. Pervasively Angry<br />Undifferentiated anger, in all areas of life.<br />Poor behavioural control and impulsivity.<br />Vindictive<br />Anger focussed solely on women.<br />Goal is to humiliate, degrade, harm their victim.<br />Usually socially isolated, displays little impulsivity.<br />Anger Motivated <br />
  6. 6. Based on needs of CSO’s (Gannon et al, 2008). <br />Meta-analytic data <br />Not enough evidence to determine whether rapist treatment approaches had been effective (Polaschek et al, 1997; Losel & Schmuker, 2005). <br />Current treatment approaches <br />Differentially effective for subgroups of rape offenders (Beech et al, 2004). <br />Rapist Classification and Treatment<br />
  7. 7. Study Questions <br /> Can the MTC: R3 be used to classify a sample of high-risk New Zealand rapists?<br /> Are there mean differences in these high-risk rapists on risk assessment scores based on MTC: R3 classifications?<br />
  8. 8. 10 offenders selected for the Adult Treatment Sex Offender Treatment Pilot Programme (ASOTP).<br />Index offence for serious sexual assault (sentenced to five years plus) of an adult victim (over 16 years old).<br />6 NZ European , 4 Maori. <br />31 - 49 years. <br />Participants<br />
  9. 9. The Risk of re-Conviction X Risk of Re-Imprisonment model (RoC*RoI) (Bakker, O’Malley, & Riley, 1998).<br />The Automated Sexual Recidivism Scale (ASRS) (Skelton, Wales & Vess, 2006). <br />The Static-99 (Hanson & Thornton, 1999). <br />The Violence Risk Scale-Sexual Offender Version (VRS-SO) (Wong, Olver, Nicholaichuk, & Gordon, 2003). <br />Measures<br />
  10. 10. Can the MTC: R3 be used to classify a sample of high-risk New Zealand rapists?<br />
  11. 11. MTC: R3 Classification<br />Figure 2: MTC:R3 Classification of the Study Sample<br />
  12. 12. Are there mean group differences on risk assessment scores?<br />
  13. 13. MTC: R3 Classification & Risk Prediction<br />Table 1. Means for Risk Measures by MTC:R3 Classification<br />
  14. 14. MTC: R3 Classification & Risk Factors<br />Figure 3: VRS:SO Risk Factors by MTC:R3 Classification<br />
  15. 15. MTC: R3 Classification & Risk Factors<br />Figure 4: VRS:SO Risk Factors by MTC:R3 Classification<br />
  16. 16. Conclusions <br />Results supported the application of the MTC: R3 typology to this sample of New Zealand high-risk rapists. <br />Mean differences on risk assessment items suggest that rapists may present differing patterns of risk on the basis of MTC: R3 classification.<br />The MTC: R3 typology may have potential applications in rapist treatment programmes.<br />
