Query Element Name Data Type Size Required Description Value Range Notes Aliases
subjectkey GUID Required The NDAR Global Unique Identifier (GUID) for research subject NDAR*
src_subject_id String 20 Required Subject ID how it's defined in lab/project
interview_date Date Required Date on which the interview/genetic test/sampling/imaging/biospecimen was completed. MM/DD/YYYY
interview_age Integer Required Age in months at the time of the interview/test/sampling/imaging. 0 :: 1260 Age is rounded to chronological month. If the research participant is 15-days-old at time of interview, the appropriate value would be 0 months. If the participant is 16-days-old, the value would be 1 month.
sex String 20 Required Sex of subject at birth M;F; O; NR M = Male; F = Female; O=Other; NR = Not reported gender
eventname String 60 Recommended The event name for which the data was collected
Query race_ethnicity Integer Recommended Race Ethnicity (Child) 1 :: 5 1 = White; 2 = Black; 3 = Hispanic; 4 = Asian; 5 = Other demo_race_ethnicity
Query rel_family_id Integer Recommended Family ID (participants belonging to the same family share a family ID). The family ID is autocalculated and will change after the addition/removal of subjects from the ABCD study. Family IDs will, therefore, differ between data releases demo_rel_family_id
Query rel_group_id Integer Recommended Group ID (twins and triplets in the same family share a group ID) demo_rel_group_id
Query rel_ingroup_order Integer Recommended In-Group Order ID (twins and triplets in the same family and in the same group have different values)
Query rel_relationship Integer Recommended Relationship of the participant in his or her family 0 ; 1 ; 2 ; 3 0 = single; 1 = sibling; 2 = twin; 3 = triplet demo_rel_relationship
Query rel_same_sex Integer Recommended Same sex twin 0 ; 1 1 = Yes; 0 = No demo_rel_same_sex
Query acs_raked_propensity_score Float Recommended Imputed raked propensity weight. The raked propensity weight merges the ACS and ABCD data (with missing data imputed), estimates the propensity model, computes and scales/trims the propensity weights and finally rakes the scaled weights to final ACS control totals by age, sex and race/ethnicity.
genetic_paired_subjectid_4 String 20 Recommended genetic related with participant based on genetic_pi_hat_4
genetic_pi_hat_1 Float Recommended Probability of identity by descend between participant and genetic_paired_subjectid_1
genetic_pi_hat_2 Float Recommended Probability of identity by descend between participant and genetic_paired_subjectid_2
genetic_pi_hat_3 Float Recommended Probability of identity by descend between participant and genetic_paired_subjectid_3
genetic_pi_hat_4 Float Recommended Probability of identity by descend between participant and genetic_paired_subjectid_4
genetic_zygosity_status_1 Integer Recommended Genetically inferred zygosity status between participant and genetic_paired_subjectid_1 -1; 1; 2; 3 1= monozygotic ; 2= dizygotic ; 3=siblings ;-1= not available (twins/sibs, genetic_pi_hat not calculated)
genetic_zygosity_status_2 Integer Recommended Genetically inferred zygosity status between participant and genetic_paired_subjectid_2 -1; 1; 2; 3 1= monozygotic ; 2= dizygotic ; 3=siblings ;-1= not available (twins/sibs, genetic_pi_hat not calculated)
genetic_zygosity_status_3 Integer Recommended Genetically inferred zygosity status between participant and genetic_paired_subjectid_3 -1; 1; 2; 3 1= monozygotic ; 2= dizygotic ; 3=siblings ;-1= not available (twins/sibs, genetic_pi_hat not calculated)

genetic_af_african Float Recommended Proportion of African ancestry genetic_ancestry_factor_african
genetic_af_european Float Recommended Proportion of European ancestry genetic_ancestry_factor_european
genetic_af_east_asian Float Recommended Proportion of East Asian ancestry genetic_ancestry_factor_east_asian

genetic_paired_subjectid_1 String 20 Recommended genetic related with participant based on genetic_pi_hat_1
genetic_paired_subjectid_2 String 20 Recommended genetic related with participant based on genetic_pi_hat_2
genetic_paired_subjectid_3 String 20 Recommended genetic related with participant based on genetic_pi_hat_3
Data Structure

This page displays the data structure defined for the measure identified in the title and structure short name. The table below displays a list of data elements in this structure (also called variables) and the following information:

  • Element Name: This is the standard element name
  • Data Type: Which type of data this element is, e.g. String, Float, File location.
  • Size: If applicable, the character limit of this element
  • Required: This column displays whether the element is Required for valid submissions, Recommended for valid submissions, Conditional on other elements, or Optional
  • Description: A basic description
  • Value Range: Which values can appear validly in this element (case sensitive for strings)
  • Notes: Expanded description or notes on coding of values
  • Aliases: A list of currently supported Aliases (alternate element names)
  • For valid elements with shared data, on the far left is a Filter button you can use to view a summary of shared data for that element and apply a query filter to your Cart based on selected value ranges

At the top of this page you can also:

  • Use the search bar to filter the elements displayed. This will not filter on the Size of Required columns
  • Download a copy of this definition in CSV format
  • Download a blank CSV submission template prepopulated with the correct structure header rows ready to fill with subject records and upload
