Maelstrom Research at McGill University has incorporated Add Health public-use data into a searchable metadata catalogue that will facilitate the identification of constructs and measures common across longitudinal studies of aging worldwide.
Maelstrom hosts an associated harmonization platform that assists in developing ways to create commensurate measures in situations where the specific variables collected differ across different studies.
Add Health public-use data is now harmonized across all four waves and variables can be compared to other longitudinal study measures by searching the Maelstrom repository.
The Add Health study profile is available on the Maelstrom Research website:
At the bottom of the page, the interaction tool allows users to browse Add Health data by standardized topics Maelstrom uses across all studies.
