  • The AASI is an invaluable component of our sex offender treatment program. Results from the AASI have helped inform our assessment of offenders' risk, while contributing to our recommendations regarding appropriate guidelines and limitations for offenders. Having the AASI 'in-house' allows us timely and flexible assessment of our own sex offender clients as well as allowing us to provide comprehensive evaluations for the courts and other treatment programs in our area.

  • In 2010 Friends for Youth became the first mentoring program in the United States to adopt The Diana Screen® as part of our existing comprehensive screening process for applicants. The safety and well-being of children and adolescents is our top priority, and The Diana Screen® is a helpful tool to assist us in selecting the best candidates to volunteer in our program. We highly recommend The Diana Screen® for all youth-serving agencies.

  • I have used the Abel Assessment for sexual interest™ over 200 times in my private practice. It has been a very useful assessment device. It has provided necessary information for both treatment plans and for testifying in court.

  • We believe strongly that if we can do something to prevent harm to the children and youth we work with, then we are obligated to do so. That something is The Diana Screen®. The Diana Screen® helps Anu to protect children from sexual abuse, sexual boundary violations, and their devastating consequences.
