Need APA help with headers and page numbers in Microsoft Word!?

I'm writing a psych paper, which has to be in APA format, not MLA. On the title page, the header has to say "Running head: UNSKILLED AND UNAWARE..." in the top left corner with the page number in the top right. However, for every other page after the title page, the header is supposed to just say "UNSKILLED AND UNAWARE..." with no "Running head" part. How the heck do I format it to work this way?
