- Very few people with cancer participate in clinical trials. Some are uncertain about the treatment, or are afraid of being treated like a guinea pig. They may also feel that they have inadequate information about the trial. One possible way of encouraging people to sign up for clinical trials is to improve the informed consent process. Researchers want to understand how people read and understand informed consent documents.


- To study perspective taking, and to study how people understand the information and enrollment process for a clinical trial.


- Healthy volunteers at least 18 years of age.


  • This study will require one study visit.
  • Participants will watch one of four movie clips. They will be asked to respond to the film by looking at it from the main character s perspective. They will then answer questions about how the clips made them feel.
  • Participants will read a sample cancer clinical trial consent form on a computer. The computer will record their eye movements while they read the text. They will then be asked whether they remember the information in the consent form, and whether they would participate in the trial.
  • No treatment will be provided as part of this study.

Further study details as provided by National Institutes of Health Clinical Center (CC):

Primary Outcome Measures:
  • Assess knowledge of side effects to participate in a clinical trial [ Time Frame: 1 year ]
  • Assess knowledge of risk perceptions to participate in a clinical trial [ Time Frame: 1 year ]
  • Assess knowledge of hypothetical intentions to participate in a clinical trial [ Time Frame: 1 year ]

Estimated Enrollment: 200
Study Start Date: November 15, 2012
Study Completion Date: October 8, 2013
Primary Completion Date: October 1, 2013 (Final data collection date for primary outcome measure)
Detailed Description:
This study aims to examine perspective-taking and emotional states. The study also aims to examine information processing in the context of clinical trial consent forms, perceptions of risk of study side effects, hypothetical intentions to enroll, and satisfaction with the consent review process. Adult human subjects will be randomly assigned to watch a movie and take the main character s. Participants will also be asked to read a consent form for a clinical trial. Finally, they will be asked a series of questions about the consent form. I have also attached changes to the lay summary, which I had previously submitted, just to make sure that you have them.

Ages Eligible for Study:   18 Years to 99 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Participants who are currently being treated for cancer will be excluded because their experience of a cancer clinical trial consent form would be qualitatively different from a noncancer patient s experience. Similarly, because individuals who have participated previously in a clinical trial might have a different perspective on participation or let previous experienced bias their perceptions of the hypothetical clinical trial context, we will also exclude individuals who have previously participated in a medical clinical trial.
