Why:

• No existing study that looks at the Fitbit data in terms of the quality of the:
  • Density of the data (i.e., how much data)
  • Longitudinality of the data (i.e., for how long)
  • Bias of the data (underlying social cohort, intra and/or inter-individual differences)

What:

• We will explore the existing Fitbit data from the ABCD study and seek to understand:
  
  • Sociodemographic data
  • The Fitbit data that is available
• Stemming from the data exploration:
  • Bias analysis

How:

• Examine the Fitbit-specific data from the ABCD
