Background: Adults with intellectual disabilities experience higher rates of exploitative intimate relationships. Parents of these adults play important roles in their lives. This study examined the role of parents in the intimate relationship experiences of adults with intellectual disabilities. Method: A mixed methods design was utilised. Parents compared experiences between their adult child with intellectual disabilities and typically developing adult child. An online survey was completed by 50 parents in the United States, and follow-up phone/video interviews were completed concurrently with a subset of 20 parents. Results: Parents reported increased involvement in relationships of their adults with intellectual disabilities. They discussed different barriers and expectations for these relationships compared to typically developing children. Parents struggled to determine appropriate levels of involvement in the romantic relationships of their children with intellectual disabilities. Conclusion: This study highlights the need for coaching and mentoring for parents to help them navigate experiences successfully.
