Step-by-step explanation:
According to research, the percentage of parents possessing an intellectual disability varies depending on the population studied. A study published in the journal 'Social Indicators Research' found that among parents in general, about 2-3% possess an intellectual disability. However, this percentage can be higher among certain subgroups such as parents of children with developmental disabilities.
One conclusion drawn by Holburn and his colleagues is that individuals with developmental disabilities can become successful and competent parents with appropriate support and interventions. They emphasize the importance of providing assistance to these parents to ensure the well-being of their children.
