TEDS Data Dictionary

Variables in the 21 Year Dataset

The table on this page lists all variables originating in data collections associated with the 21 Year study (TEDS 21, g-game, Covid studies). This includes both item-level and derived variables.

The table does not include background variables that originate from other sources (either from admin data or from other study datasets). Such variables include IDs, twin sex and zygosity variables, the random variable and general exclusion variables. See the background variables page for details.

Variables are listed in alphabetical order in the table below. The columns of the table are:

  • Dataset variable name
  • Dataset variable label
  • Item or derived variable?
  • Source of data:
    • parent phase 1 - from the TEDS21 parent phase 1 questionnaire (prefix u1p)
    • twin phase 1 - from the TEDS21 twin phase 1 questionnaire (prefix u1c)
    • twin phase 2 - from the TEDS21 twin phase 2 questionnaire (prefix u2c)
    • g-game - from the twin g-game study (prefix ucg)
    • covid-1 - from the Covid study phase 1 twin questionnaire (prefix ucv1)
    • covid-2 - from the Covid study phase 2 twin questionnaire (prefix ucv2)
    • covid-3 - from the Covid study phase 3 twin questionnaire (prefix ucv3)
    • covid-4 - from the Covid study phase 4 twin questionnaire (prefix ucv4)
    • admin - administrative data, logged in the TEDS admin database
  • Data type:
    • integer - numeric whole numbers
    • decimal - numeric with fractional values
    • string - alphanumeric character strings
  • Variable type:
    • nominal - categorical, with arbitrary values
    • ordinal - categorical, with ordered numeric values
    • quantitative - numerical measurements of some concrete quantity
    • scale value - numerical measurement derived (usually) as a sum or mean of other variables
    In some cases, these distinctions are arbitrary. Binary variables are categorized as ordinal if they are scores (0/1), and nominal otherwise.
  • Coding or range of values - this shows the value coding used for nominal/ordinal variables, or an approximate range of values for quantitative and scale variables.
