Molestation Prevention Study". The report was never subject to peer review or published in any professional journal. There is also no in-depth detail about his methodology available. The Abel Assessment is based on these findings. In a 2002 decision on the admissibility of the test by Texas appellate judge Brian Quinn, the court said that since Abel's proprietary scoring methodology is not publicly known, it "could be mathematically based, founded upon indisputable empirical research, or simply the magic of young Harry Potter's mixing potions at the Hogwarts School of Witchcraft and Wizardry". Abel states in his book that a therapist can use the test as a tool to determine if a child is attracted to other children. The 9th Circuit Court of Appeals also ruled in 2004 that the Abel Assessment is a tool that is used only as treatment, and that it cannot detect whether a person has sexually abused children. Independent studies of the Abel Assessment have concluded it to be unreliable in adults and that there is not yet enough information to support its use with adolescents. The Diana Screen is another test developed by Abel and his associates. It, too, has been a source of controversy for Abel due to it being a pass/fail test.
