6. Research with the HCR-20 & SAPROF
Van der Hoeven Kliniek, The Netherlands
1. Retrospective file study
- N = 188 violent + sexual ♂
- 108 also pre-treatment rating
- Treatment length 5.7 years
- Outcome: Reconvictions for violence
- Follow-up in community after discharge
- 1 year
- 3 year
- M = 11 year

2. Prospective clinical study
• 879 assessments on 325 offenders ♂/♀ (max 1 RA / stage)
- intramural (233)
- supervised leaves (159)
- unsupervised leaves (141)
- transmural first (162)
- transmural last (113)
- discharge (72)
• Outcome for 315 assessments:
- Violent incidents during treatment (12 months)

18. Dynamics of risk assessment
HCR-20 & SAPROF
• The dynamic factors HCR-20 & SAPROF
show clinically valuable changes in risk and
protective factors
• The more change, the less recidivism
• Individual change in clinical practice is less
smooth than the group average suggests
