Depressed adults and the effects on children

Hi everyone,
I wrote my paper about how having a depressed parent or parents is negatively impacting millions of childrens and adolescents and what needs to be done to to minimize some of these effects. Over 15 million children under the age of 18 will reside with a depressed parent each year. This results in these children having problems with growth and development, depression, behaviour, and socialization.
Currently there are several tools that screen for depression in adults, they don't however take the next step and pick out adults that have children at home. Implementing such a tool seems so easy, "Do you have children living in your household?" yes or no. If the answer is yes, additional intervention needs to be implemented to ensure that the kids are not being adversely affected.
Addtionally, I would like to see a simple questionaire for adults and children who are entering the healthcare system for other reasons. Doing this would allow for early intervention, and would open up treatment options for more people. Depression is such a huge problem, I feel as a nurse it is my personal responsibility to be on the look out for it, to provide education to patients about it, and to help people get the help that they need.
