24 Base Rates Matter MoreOrFewer Reoffenders for each score

25 Which Norms to Use Correctional Services of Canada Routine Cases N = 2406 No screening procedures No pre-selection for tx, or civil commitment

26 Which Norms To Use? Preselected for Treatment Referred for sex offender specific treatment during current or prior incarceration Selected but no beds still selected

27 Which Norms to Use High Risk Sample Preselected for risk Preselected for risk Factors external to Static-99 Factors external to Static-99 SVP referral, mentally disordered, not guilty by reason of insanity, referred for intensive treatment SVP referral, mentally disordered, not guilty by reason of insanity, referred for intensive treatment

28 Non-routine Treatment sample Treatment sample High risk samples High risk samples Preselected for other reasons, e.g., offense severi Preselected for other reasons, e.g., offense severi

45 Aging and Risk of Sexual Offending

46 What Difference Does Age Make? Recidivism & aging -.10 (Hanson & Bussiere, 1998) Recidivism rates declined steadily with age Extrafamilial child molesters – maintained risk longer N =3751 (Hanson, 2002)

47 Age-at-release from custody Recidivism rate (%) Child molesters Rapists Incest offenders

48 Age & Recidivism Reanalysis of Hanson All groups declined steadily Own data – linear decrease with age N = 468 (Barbaree et al., 2003)

49 Fitted Sexual Recidivism Rates by Age Graphs

50 Each one unit increase in age was associated with 98% of the recidivism rate of the previous (younger) age Each one unit increase in age was associated with 98% of the recidivism rate of the previous (younger) age Recidivism rate of 32-year-olds was 98% of recidivism rate of 31 year- olds Recidivism rate of 32-year-olds was 98% of recidivism rate of 31 year- olds

51 Current age item did not adequately adjust for age Could have left old item and “fitted a complicated curvilinear age adjustment” Decided instead to create a new age item

52 With New Age Item Age of release does not add significant incremental predictive validity With old age item – Age of release does add predictive validity Meaning: New item adequately controls for age

69 Reduction in Criminality with Age 1/2 Reduce Criminal Activity 1/2 Reduce Criminal Activity About 35 to 40 Not for Violent Crime (Hare, McPherson & Forth, 1988; Harris, Rice & Cormier, 1991)

71 Psychopathy & Aging Almost ½ of psychopaths convicted of crimes after 40 Percentage of violent crimes increased (Hare et al., 1992)

72 “It appears that the psychopath’s propensity for violence and aggression may be relatively persistent across much of the life span.” (Hare, 1992, p.295)

73 Days Free on Conditional Release as a Function of PCL-R & Age Porter et al., 2001 Age Mean # Successful Days N = 224 N = 93

74 Older Psychopaths & Time in Community Age 30 40 – 441000 days200 days 45 – 492500 days100 days (Porter et al., 2001)

75 “We found no evidence that older offenders scoring high on the PCL-R were more successful than their younger counterparts.” (Porter et al., 2001)

76 “Clearly, older psychopaths had far less opportunity to offend... This suggests that the age-related decline in criminal charges and convictions for psychopaths was, in part, an artifact, and that the criminal (and violent) propensities of the aging psychopaths may have been greatly underestimated.” (Hare, 2003, p. 62)
