Some people have difficulties with reading, writing or math, have a low IQ or have difficulties understanding health information. These people are on average less healthy. Yet, little collaboration exists with this group in health research. We want to change this and collaborate on a structural basis. We do this with a permanent advisory group with people from this group. The advisory group advises health scientists on research. We want to encourage fellow scientists to ask the advisory group for advice more often. In addition, we want advisory group members to be able to participate as researchers in some studies.
