Which approach would attempt to minimize psychological disorders by working to reduce the incidence of child abuse and illiteracy in society?

I believe the answer is: Prevention

The prevention approach includes various efforts that intiated by intervening with an occurence before it even happen.

In the scenario above, reducing child abuse and illiteracy would increase the likelihood of those children to grow up with healthy mental state and proper cognitive development, which decrease the chance of a psychological disorder from occuring.
