The present study was initiated to design and evaluate a sexual abuse prevention program for deaf and hard of hearing (DHH) children. This evidence-based prevention program is the first of its kind for DHH children. A total of 92 DHH children aged 8-12 years participated in the program "STARK mit SAM" (Strong with Sam, SmS), a program conducted in primary schools for DHH children in Germany. The program evaluation consisted of a pretest-posttest design. As per class, the subjects were assigned to either the experimental or the wait list control group. Participants from both groups were pretested for their knowledge about content related to the prevention of sexual abuse. The experimental group received the prevention program and both groups were posttested to examine the effects of the program. Additionally, the experimental group was tested again 6 months after the program. DHH children who participated in the SmS program showed a significant knowledge gain and a nonsignificant change in their anxiety. No significant factor affecting the children's significant knowledge gain was found. SmS is an effective sexual abuse prevention program for DHH children, which can be offered without incurring anxiety in the children.
