There is some confusion among students in question 11 for this assignment. The wording of the question is problematical. They are to find a book chapter that includes information about the effectiveness of relaxation techniques for the treatment of migraine headaches in children. The confusion comes form trying to a chapter on the web. What they need to do, since this is a PsycInfo assignment, is use the limiters in the original search to to set the "Age Groups" menu to all six of the groups (Control Click), then set the "Document Type" menu to "Chapters". This will change the search to the area they need. It isn't necessary to change the "Publication Type" menu to "All Books."
