This manual was prepared to guide a pilot test, in April 2002 in Mangochi Distric , Malawi, of a research method called Diagnostic Role Play (DRP). Carried out by the CHANGE Project with Save the Children/Malawi’s School Health and Nutrition Program, the pilot test focused on various preventive behaviors related to HIV/AIDS. After this experience, the manual was somewhat revised to reflect lessons learned (summarized in the box below). The manual is now offered for the use of program planners and researchers in general. It is hoped that they will find it helpful and that they will give the CHANGE Project feedback so that the method can continue to be improved. - See more at: http://www.popline.org/node/241030#sthash.W0aL5qC3.dpuf
