The sexual assault of adult women is noteworthy by its huge social and
personal cost to the victims, their families, and ultimately society
as a whole. The past decade has seen burgeoning research and clinical
interest regarding child molesters but a lack of equivalent effort con
cerning rapists. Rapists are significantly different from child molest
ers. While considerable heterogeneity exists within this group, there
is a lack of distinctiveness when compared to the wider population of
serious criminal offenders. These two features of rapists have implica
tions both for research and treatment. We also argue that despite the
advances of the last decade this has been in terms of theory prolifera
tion rather than integration, and that major explanatory gaps remain.
In particular; there is a need for more middle-level theory that artic
ulates mechanisms and can underpin treatment. Current treatment approa
ches have typically been developed for child molesters, and while ther
e has been a significant increase in comprehensiveness and sophisticat
ion, the evidence for treatment efficacy with rapists remains tentativ
e. Treatment programs need to be tailored to the specific needs of rap
ists and to the issues of treatment engagement and completion. We conc
lude with a variety of suggestions for the research agenda over the ne
xt decade. (C) 1997 Elsevier Science Ltd.
