Common Data Elements (CDEs) Repository
The NIH HEAL Initiative’s aims to harmonize the data collected by the initiative’s studies, enhancing the comparability of various data sets generated by HEAL research.
HEAL researchers and potential applicants conducting research with human participants should also prioritize using the HEAL CDEs. Researchers outside the HEAL Initiative conducting pain research may also be interested in using validated and structured questionnaires.
The 'core' questionnaires in ten domains, demographic information, and opioid usage are required for the human subjects in pain HEAL grants and are organized depending on the type of pain and population being studied.
