In Person: Abbreviated Diabetes Knowledge Test (DKT)
JDIAB Abbreviated Diabetes Knowledge Test (DKT) Module OVERVIEW The Abbreviated Diabetes Knowledge Test Module is new to the 2011 collection wave. At its core are selected questions from the 23-item "Diabetes Knowledge Test (DKT)," which assesses general knowledge about diabetes using a multiple choice format. The first fourteen items of the DKT can be appropriately administered to both diabetics and non-diabetics, while the subsequent nine items should only be administered to diabetics who use insulin. Within the context of the CAPI interview, seven DKT items appropriate for both diabetics and non-diabetics were asked to a randomly selected 15% sub-sample of participants, as well as all participants who - in the Health Module - reported ever having been diagnosed with diabetes. DKT items selected for inclusion in this module addressed the following: the nutritional value of various foods relative to others; measurement of blood glucose levels, as well as their sensitivity to different foods; and risk factors and complications associated with diabetes. For more information about the unabridged Diabetes Knowledge Test, please see http://www.med.umich.edu/mdrtc/profs/survey.html#dkt.
