Protocol - Trust in Medical Researchers - 12-Item
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.
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 email@example.com. If your intention is to use the protocol in a for-profit or commercial environment, please contact firstname.lastname@example.org 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.
Trust in Medical Researchers 12-Item
Participants are first asked the following item regarding willingness to participate: “If you were approached by someone at the [university/institute] to participate in a study, how likely would you be to volunteer to participate in the next 3 months?” Responses were likely, somewhat likely, not likely, or not likely at all to participate.
| Strongly |
|Disagree||Neutral||Agree|| Strongly |
|1||Doctors who do medical research care only about what is best for each patient.||1||2||3||4||5|
|2||Medical researchers treat people like “guinea pigs.”||1||2||3||4||5|
|3||It’s safe to be in a medical research study.||1||2||3||4||5|
|4||Some doctors do medical research for selfish reasons.||1||2||3||4||5|
|5||Doctors tell their patients everything they need to know about being in a research study.||1||2||3||4||5|
|6||A doctor would never ask me to be in a medical research study if the doctor thought there was any chance it might harm me.||1||2||3||4||5|
|7||There are some things about medical research that I do not trust at all.||1||2||3||4||5|
|8||A doctor would never recommend something that is not the best treatment, just so he or she can study how it works.||1||2||3||4||5|
|9||Medical researchers have no selfish reasons for doing research studies.||1||2||3||4||5|
|10||Medical researchers do not tell people everything they really need to know about being in a research study.||1||2||3||4||5|
|11||The only reason doctors do medical research is to help people.||1||2||3||4||5|
|12||I completely trust doctors who do medical research.||1||2||3||4||5|
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.
|Specialized requirements for biospecimen collection||No|
|Average time of greater than 15 minutes in an unaffected individual||No|
Mode of Administration
Ages 18 and older
This is a low-burden protocol that allows investigators to assess trust in physicians doing medical research in addition to assessing trust in medical research or research generally.
