For those who have not yet had a chance to read your paper, could you provide a very brief overview of the study and its aims, please?
Michael CulbertsonGUEST
This study all began with a measurement challenge that we had in the high school and beyond study of 1980.
Michael CulbertsonGUEST
We were following up with a cohort of individuals who had participated in an education study back when they were in high school students in 1980.
Michael CulbertsonGUEST
And now these are older adults and we've reactivated the cohort as an aging study.
Michael CulbertsonGUEST
But when we were fielding in 2021, we had to divide the sample into two sub cohorts, a phone sample and a web sample for budgetary constraints.
Michael CulbertsonGUEST
And this posed a measurement challenge because the participants who were responding via the phone had different cognitive tasks than the participants who responded via web.
Michael CulbertsonGUEST
But we needed some way to make the measurements comparable across those two tasks.
