This paper reviews the state of research into treatment programmes for adolescent sexual offenders, focusing first on treatment dropout, then on recidivism studies. Pre-treatment variables, which may predict dropout from programmes for these adolescents, have hardly been considered, despite obvious financial and ethical implications. In relation to recidivism studies, these have been carried out quite consistently since the mid 1980s, yet, as is discussed, they still suffer from many methodological problems. The authors also note that research into treatment programmes comes almost exclusively from North America. Thus, such research needs replicating with UK samples in order to assure the applicability of any research findings to this population.
