Frequently Asked Questions

Q. What is the most current Einstein Aging Study (EAS) Data Release?
A. The most recent (January 2025 data release) brings all primary releasable datasets current, spanning February 2023 through December 2024.

Q. How do I get access to the additional data beyond the release?
A. Due to changes in EAS data management policies, additional data not contained herein is available upon request with approved concept proposal.

Q. What data is included in this release?
A. This data release includes all data from February 2023 and beyond for all participants completing the new protocol, through December 2024. This is an EAS draft data release to prioritize AAIC and other conference abstracts from newly collected data. A final version of this data release will include more data streams over the course of 2025. The deliverables herein should be considered addendums to prior EAS closed datasets.

Q. What deliverables does the current release include?
A. The list below includes all deliverables, organized by category and level of analysis.

Q. Are all data releases the same?
A. No, there are changes in between data sets. In the future there might be more changes. please read the read-me’s attached to data releases. Below, you can read about some of the changes that have taken place

Q. Mobile app data collection
A. For the February 2023 through December 2024 period, we switched mobile apps for data collection, meaning if these files are stacked with prior data releases, care should be paid to how this merge should take place. Please contact Dr. Nelson Roque (nur375@psu.edu) of the TDM Core for more information. If you are in the midst of a revise and resubmit with a prior dataset, do not use the latest dataset for those revision purposes, as ambulatory cognitive variable calculations may be subtly different (e.g., due to rounding error; differences in implementation of flags).

Q. Identifiers
A. Participants across prior releases had various identifiers (e.g., Id, ID, Subject Id, EAS ID, GCRC Id). In an effort to reduce confusion, all participants are now labelled participant_id across the deliverables herein.

Q. Cohort definition
A. If participant_id >= 13000 then cohort=2; /new new cohort, 2023 and beyond/ if participant_id >= 12000 then cohort=1; /new cohort, 2017 – early 2023/ if participant_id < 12000 then cohort=0; /old cohort, prior to 2017/

Q. Burst Definitions
A. Bursts 1-6 correspond to each year’s EMA protocol period. • Burst = 0 means that the participant never did the EMA. Burst = 99 means that the participant did the EMA in previous waves but did not do it that wave. This can change from year to year.

Q. Dates, Times
A. In an effort to clarify timestamps across EMA data, all date/time stamps were reduced to a set of columns, herein: dt_start_date, dt_start_time, dt_end_date, dt_end_time
