The impact of sexual abuse on body experience in adults with mild intellectual disability or borderline intellectual functioning Open
Adults with MID-BIF who were sexually abused are more aware of their body signals, but less able to adequately attend to, tolerate, and interpret these signals. Therefore, body- and movement-oriented therapies hold promise for this group.
