Too little is being done to protect people with learning disabilities from abuse, researchers have found.
The University of Glamorgan study, which was conducted by academics and people with learning disabilities, also found that those who reported abuse were often not believed or supported.
People reported being abused in a variety of settings, including on public transport and in schools.
The Welsh government said it was trying to tackle disability-related abuse.
