Any chance that we can get sleep diary data from MESA? or should I contact the MESA center? We are looking at different "bedtime" definitions, and would like to use MESA data as an example.
Thank you very your quick response! I am a little confused by the actiware onset detection of "5 minutes of immobile time". For example, if there is 5 minutes of immobile time from the start of REST interval, then the SOL is 0 min? I am confused because the mean is actually less than 5 min (4.8 min), and there are subjects with 0 min SOL.
I am working on the MESA actigraphy data. And I found that the average sleep onset latency in the summarised dataset is around 5 min, which is much shorter than the average SOL reported for this age range (~15 min). I read the MESA actigraphy scoring manual, and I think the short SOL may be related to how scorers defined bedtime when cleaning actigraphy data.
Do you guys know who on the MESA team I should contact and ask about their bedtime definition?
I switched to a windows computer and was able to unzip successfully. I guess it's a Mac issue then. Thank you!
I just downloaded the STAGE actigraphy data zip, but when I unzip it there is nothing in the folder. I tried both archival and Stuffit. Can you help check if the zip file is damaged?
