Known Issues & Pending UpdatesšŸ”—

Active Items Only

This page lists ACTIVE issues/pending updates either targeted for upcoming BRs or still pending final Workgroup/SME sign-off. Items are not considered resolved until final review and approval by Workgroup/SME. Note that items addressed in a BR are not reflected as resolved in the public release documentation until the corresponding PR is released.

FOR A LIST OF RESOLVED ITEMS, SEE Resolved Issues & Updates Archive

Behavior & Child-Caregiver InteractionšŸ”—

Table/TopicSummary
FAD N=4 V06 participants with <3 item responses are incorrectly scored as 0; set values to null prior to analysis. R3
MAPS-TL (<1yr) N=4 participants with no item responses are incorrectly scored as 0; set values to null prior to analysis. R3
ecPROMIS CC N=12 V03 participants with <3 item responses are incorrectly scored as 0 in mh_cg_pms__cc__inf; set values to null prior to analysis. R3
ERICA A future release will include reliability codes integrated into the primary coding dataset. Until then, users must perform this integration manually: see the ERICA Data Warning for instructions.
Instructions include cleaning the current files to exclude n=44 participants with incorrect code values (data entry/form errors) and capping b_raw values at 3.0 (n=3 participants). These issues will also be corrected in future release data.		 R3
ERICA Remove locomotor_ability fields from both tables TBD
ERICA Add all age and date_taken fields (currently excluded due to use of coding rather than visit dates). R3
MAPS-TL (Tod) Pro-rated scoring for mh_cg_mapdb__tod not yet implemented; N=16 participants missing scores. R3

Biospecimens & OmicsšŸ”—

Table/TopicSummary
Nails Nail type is 4 (Unknown) in the main results table (*_nails_results) and should be obtained from the specimen table (*_nails_type). R3
Blood Inclusion of Blood Spot Card Results data from USDTL. R3

DemographicsšŸ”—

Table/TopicSummary
Basic Demo N=14 participants in sed_basic_demographics have a Maternal Age at V01 of 0; exclude these values from analyses until corrected. R3
RESTRUCTURE The Demographics domain includes 2 tables with derived information grouped into visit-specific data (Visit Info) and general demographics (Basic Demographics). In a future release, these tables will be restructured to instead organize variables as either longitudinal (dynamic measures that change over time) or global (static measures, such as sex assigned at birth and race/ethnicity). R3
SU Flags A derived/rolled up substance use flag for Stimulants will be added based on positive instrument-specific Stimulant results. 21.2

EEGšŸ”—

Table/TopicSummary
Age fields Chronological and adjusted age fall outside of 3-9 months in N=74 V03 sessions (site entry errors); exclude age values prior to analysis. TBD

GeneralšŸ”—

Table/TopicSummary
Implausible GA A small subset of participants have implausible gestational_age (V01 only) values for one or more instrument. Until corrected, review GA distribution to exclude outliers from analysis (should be positive and generally < 45 weeks). R3
Instruction The 'instruction' data dictionary element is currently blank. R3
Multibirth Cohorts Missing instrument fields for Sibling cohorts will be populated and FamilyID will be added to help identify siblings - see details. R3
Score text Text inappropriately located in score fields where score is missing to be moved to corresponding 'notes' field (impacts ecPROMIS-PAGS; MAPS-TL: SPM-2). R3
Sequence Field The currently included Sequence field is blank across all instruments and will be removed. TBD

MRIšŸ”—

Table/TopicSummary
Run ID The run-{X} field may not reflect chronological acquisition order. While this affects both raw BIDS and derivatives, data remain internally consistent (i.e. run IDs match between raw and processed datasets). TBD
Cook's Distance Addition Cook's distance values computed for fMRI. R3
QSIRecon Tabulated data for QSIRecon (participant data combined across derivative files into single tidy table) will be provided in a future release. TBD
Scanner Info Scanner information must currently be parsed from raw BIDS data (specifically the scans .tsv files), as described here. Future releases will include a dedicated 'MRI Info' table that summarizes scanner information across participants, similar to the ABCD study (see details). R3
Source DICOMs Add source DICOMs for all imaging modalities. R3

Neurocognition & LanguagešŸ”—

Table/TopicSummary
MLDS Total non-parental hours/week (ncl_ch_mlds_arr_hr_wk) includes implausible values due to data entry errors. Exclude values >168 hours from analysis. TBD
SPM-2 Add missing raw and T-scores 21.2

Novel Tech & Wearable SensorsšŸ”—

Table/TopicSummary
GABI Addition of raw BIDS data for GABI (infant heart rate). R3

Physical HealthšŸ”—

Table/TopicSummary
Growth The data dictionary element type_data for average_bmi will be corrected to double (currently=character). R3
Growth Growth (ph_ch_anthro) filter ranges will be updated to be visit-specific, as current ranges allow biologically implausible values (see Range Checks). R3
Growth Adjusted age contains N=303 "unknown missing" values that are also missing 'Date of Administration'. R3
BISQ-SF Add Infant Sleep (IS) sub-scale score to ph_cg_bisq. TBD
Growth Add sex-specific birth weight to ph_ch_anthro (see Sex-Specific Birthweight for GA). R3
Vision Screener Add more fields to ph_ch_vs (current release only includes completion status and overall screening results). TBD
ecPROMIS-PAGS Add scores to ph_cg_pms__pags. Until added, scores can be calculated by following the Scoring Procedures documentation. 21.2

Pregnancy & Environmental ExposurešŸ”—

Table/TopicSummary
EPDS Inconsistent scoring: (1) item responses present, but score is null (N=1); (2) all items null, but score is 0 (Nā‰„3). R3
Healthv2 Preg The field for the date when PNV was stopped (pex_bm_healthv2_preg__exp__pnv_007__01) is blank, despite participants having reported stopping. R3
Healthv2 Preg Note that items about aspirin use (pex_bm_healthv2_preg__exp__pnv_{011|012}) are largely blank. R3
TLFB PNR data were incorrectly reported using TLFB versions 1/2 and will be updated to version 3 specific to PNR. TBD
PEX Health ICD codes for the pex_bm_health* tables are inconsistently provided, sometimes missing corresponding names/labels. For example, medication names are present for the Health V1- Medications, while the Health V2- Pregnancy instrument only has medication codes without corresponding labels. Until resolved, users can use external packages to merge ICD labels if needed: Stata, SAS, R R3

Social & Environmental DeterminantsšŸ”—

Table/TopicSummary
Demo Relationship status was inappropriately collected at V02/V03 for all cohorts and should have been restricted to cases where there was a change in caregiver (i.e. only Alternative Caregiver cohorts should have this field populated). Data for non-ACG cohorts to be excluded. R3
Demo Roster was inappropriately collected at V02/V03 for all cohorts and should have been restricted to V02 PNRs and alternate caregiver cohorts; to be excluded. R3
eHITS Participants missing all item responses are incorrectly scored as 0; set values to null prior to analysis. 21.2
Demo Add household roster fields capturing the sex of listed individuals (adult & child tables). R3
