Protocol - Trust in Medical Researchers - 12-Item
Description
The Trust in Medical Researchers 12-Item scale is a validated interviewer-administered 12-item questionnaire. Items are scored 1-5, strongly disagree to strongly agree, with negative items reverse-coded so that higher score indicates more trust. The scores from the 12 items are summed unweighted, and 12 is subtracted from the total. The total will range from 0 to 48, with the higher the score the greater the trust in medical researchers.
Specific Instructions
Investigators may choose the 12-item scale over the 4-item scale in situations when they want to more fully capture and measure trust of medical care and research. The Trust in Medical Researchers scale has not been validated in non-U.S. populations.
The Trust in Medical Researchers scale is for academic and nonprofit purposes only. For documentation and instructions, contact bioethics@wfu.edu. If your intention is to use the protocol in a for-profit or commercial environment, please contact bioethics@wfu.edu to request permission and obtain licensing information before use. Also, a license is required for any research that is subject to 3rd-party rights (e.g., industry-sponsored research that grants rights to the sponsor). For permitted uses, you may make minor adaptations of the phrasing to fit particular circumstances or modes of survey administration. Otherwise, you may not translate or substantially modify the tool without additional permission. If a derivative work is created based on the scale, the work will be owned by Wake Forest University.

Scoring: The scores from the 12 items are summed unweighted, and 12 is subtracted from the total. The total will range from 0-48, with the higher the score, the greater the trust in medical researchers. Items # 2, 4, 7, 10 and 3 are reverse-coded.
Personnel and Training Required
The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer should be trained to prompt respondents further if a “don’t know” response is provided. The interviewer must be found to be competent (i.e., performance approved by an expert) at the completion of the interviews.
