Over the past 20 years, Bob and his colleagues have developed risk assessment tools to help mental health, probation, parole, and child protection services professionals better assess, treat, and manage men who have committed sexual offenses. For more information about these tools, click on the blue links below.
Sex Offender Treatment Intervention and Progress Scale
The SOTIPS is a 16-item dynamic risk instrument used to assess risk, treatment and supervision needs, and progress among adult male sex offenders. It should be combined with a static risk tool such as the VASOR-2 or the Static-99R. The SOTIPS Manual is available for use at no cost. For more information, Click Here.
Vermont Assessment of Sex Offender Risk-2
The VASOR-2 is a static risk instrument used to assess risk among adult male sex offenders. It comprises a 12-item Reoffense Risk Scale and a 4-item Severity Factors Checklist. Ideally, the VASOR-2 should be used in combination with the SOTIPS. The VASOR-2 Manual is available for use at no cost. For more information, Click Here.
Risk of Sexual Abuse
of Children
The ROSAC is a 30-item structured professional guide used to assess the risk an adult male sexual abuser poses to a particular child and under what circumstances the abuser might safely be allowed contact with the child. The ROSAC Manual is available for purchase from Safer Society Press. For more information, Click Here.
