Personnel and Training Required

The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.

Equipment Needs

These questions can be administered in a computerized or non-computerized format (i.e., paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.

Mode of Administration

Interviewer-administered questionnaire

Life Stage:

Adult, Senior

Participants:

An individual aged 18 or older. The protocol can also be administered to a child through an adult proxy.

Specific Instructions:

The following was taken from a stem question that captures more than just a personal history of diabetes. The Diabetes Working Group (WG) recommends removing "one of the following" from the initial question so that the question is "Has your doctor or health care professional told you that you had:" The Diabetes WG refers users to the Female Protocol of the Reproductive History measure for more questions on pregnancy history related to gestational diabetes.

The Expert Review Panel suggests that a question is asked about history of hospitalization for diabetes - ketoacidosis to help differentiate between type 1 diabetes mellitus and type 2 diabetes mellitus.

Selection Rationale

The Multi-Ethnic Study of Arthrosclerosis (MESA) protocol was vetted against similar protocols and chosen because it captures age of diagnosis, whether the respondent is taking medication for diabetes, and whether the diagnosis was just during pregnancy (history of gestational diabetes mellitus [GDM]).
