To illustrate the difference in the modified Abel and the Abel “Methods of Thirds”, subject # 1 self- reported an interest in adolescent and adult males. His known victims were boys aged 12 to 17. Using the Abel “Method of Thirds” per manufacturer instructions, the interest preferences included young and adolescent females, and young, adolescent, and adult males. Using the modified Abel, the selection was truncated to adolescent and adult males, the exact interest preferences self-reported by the patient (Table III).
