Sexual assault prevention for women with intellectual disabilities: a critical review of the evidence.

Wacker et al. (2009) · Intellectual and developmental disabilities 2009
★ The Verdict

Only four sexual-assault-prevention programs exist for women with ID, and none are proven to work.

✓ Read this if BCBAs who serve teen or adult women with intellectual disabilities in day or residential programs.
✗ Skip if Clinicians whose caseloads are mostly autism without ID or children under ten.

01Research in Context

01

What this study did

Wacker et al. (2009) searched for programs that teach women with intellectual disabilities how to avoid sexual assault.

They read every paper they could find and counted how many programs had been tested.

The team also looked at how strong the tests were.

02

What they found

Only four programs existed, and none had solid proof that they work.

All four studies were small or lacked follow-up.

03

How this fits with other research

Farrant et al. (1998) tested one of those four programs. Adults learned the skills in class but could not use them in real-life probes. This matches Julia’s warning that proof is thin.

Maddox et al. (2015) later reviewed children with ID and found the same gap: almost no prevention programs. Together, the two reviews show the problem spans both women and children.

Armas Junco et al. (2025) widened the lens. Their systematic review found almost no research on sex education that includes LGTBIQA+ clients with ID. The empty shelf keeps growing.

04

Why it matters

You probably have clients with ID who receive no assault-prevention teaching. This paper tells you not to trust the few packaged programs that claim to be evidence-based. Instead, add extra generalization steps, track safety skills in real settings, and push for better curricula. Your data can help fill the research gap.

03Original abstract

Although research has indicated that women with intellectual disabilities are significantly burdened with sexual violence, there is a dearth of sexual assault prevention research for them. To help address this serious knowledge gap, the authors summarize the findings of general sexual assault prevention research and discuss its implications for women with intellectual disabilities. Next, the authors evaluate interventions published in both the peer-reviewed and non-peer-reviewed literature from a comprehensive search of the scientific literature as well as from recommendations made by disability and sexual assault service providers in the United States. The results of this comprehensive literature review found 4 sexual violence prevention programs that were designed for participants with intellectual disabilities and that had undergone some type of evaluation. Each program and its evaluation are critically and systematically reviewed. Based on the authors' review of these programs as well as the wider literature, they conclude with recommendations and discuss the work that remains to decrease the incidence of sexual violence against women with intellectual disabilities.
