A proposed version of these standards was first produced and published in the Journal of Offender Rehabilitation; subsequent changes have been incorporated into this version. These Standards of Care were unanimously endorsed by the participants in the Third International Congress on the Treatment of Sex Offenders, September 1994. The article includes statement of purpose, definitions, description of professional competence, antecedents to sex offender treatment (extensive evaluation of their behavior, thorough physical and psychological/psychiatric examinations, information regarding biomedical treatment), and the 14 principles of standards of care. The principles refer to, among other things, effectiveness of treatment, types of treatment plans, legal matters of concern to both the offender and treatment professionals, follow-up treatments, and patient confidentiality.
