Book excerpt: It is estimated that relapse prevention methods are employed in more than 90% of all North American sex offender treatment programs (of which there are more than 2,000). Comparable statistics are true in most industrialized countries around the world. Over the last decade a great deal has been learned about the treatment of sexual offenders, and particularly about relapse prevention. This sourcebook provides clinicians with the most current, practical, useable information about working with sex offenders to prevent relapse. It reflects the advances and insights of the past decade since the publication of Relapse Prevention with Sex Offenders , focusing on the major reconceptualizations, revisions, and innovations that will chart treatment programs for the first decade of the new millennium.
