ABCD Fitbit and Sleep data
Phoebe Chen
Hi,
We would like to ask a couple of questions about downloading Fitbit and Sleep data from the ABCD dataset.
1. Questions about Fitbit Sleep Data
My colleague downloaded the “ABCD Youth Fitbit Daily Sleep Summaries” (abcd_fbdss01) and “ABCD Youth Fitbit Weekly Sleep Summaries” (abcd_fbwss01) data on 4th November, 2023. It has about 150,000 rows of data with both data from baseline year and 2-year follow-up but the format seems misaligned for some columns. So, we downloaded the “ABCD Youth Fitbit Daily Sleep Summaries” (abcd_fbdss01.txt) again on 17th Nov, which only includes 5891 rows of data with only 120 subjects from their 2-year follow-up data. While the format of this new file is correct, we wonder why the number of data differs tremendously. We would also like to ask what the differences are between the two files and ask for your suggestion about which file of data we should use for data analyses.
2. Questions about other data
We created a package including the above-mentioned Fitbit sleep data and the following data on 17th Nov. After downloading the full package, the following files are missing. (i.e. only Fitbit sleep data are downloadable)
l ABCD Youth Munich Chronotype Questionnaire (abcd_mcqc01)
l ABCD Parent Sleep Disturbance Scale for Children (SDS) (abcd_sds01)
l ABCD Parent Diagnostic Interview for DSM-5 Full (KSADS-5) (abcd_ksad01)
l ABCD Youth Diagnostic Interview for DSM-5 5 (KSADS-5) (abcd_ksad501)
It would be great if you could let us know why and how we can solve this problem.
We look forward to your reply. Thank you very much for your help.
Kind regards,
Phoebe
