Under the supervision of the principal investigator of CDRCC, two different subcommittees will oversee the different aspects of the UTSW Depression Cohort: data management committee and executive committee. The data management committee will be tasked with managing the flow of information into and out of the Cohort database, maintaining the codebook of variables, developing big data tools (as mentioned in specific aim 3), and ensuring consistency of data collection and quality. The executive committee will be tasked with all other responsibilities related to the registry like establishing collaborations with providers, reviewing research proposals, and providing access to the cohort data for qualified researchers.
