Gene Gordon Abel is an American psychiatrist and controversial clinician. He is a couple's counselor and also works with men and boys suspected of sexual deviancy. He is the creator of the Abel Assessment for Sexual Interest (AASI), a sex offender assessment tool that has been considered unreliable by independent studies and inadmissible in court in various jurisdictions. He also designed a screening test called the Diana Screen, to be used, e.g., to screen job applicants for deviant sexual tendencies – a test which has been similarly criticized as having dubious scientific value.
