Adolescent Brain Cognitive Development (ABCD) Study

The Adolescent Brain Cognitive Development (ABCD) Study© is the largest long-term study of brain development and child health in the United States, with 11,880 children between the ages of 9 and 10 having been invited to join the study. The ABCD study is funded by the National Institutes of Health (NIH) and is associated with 21 research sites across the country. Researchers seek to explore how childhood experiences interact to affect cognitive, social, emotional, and physical development during adolescence. The goal of the ABCD study is to provide families, schools, professionals, and policy makers with crucial information needed to promote the health, well-being, and success of children.

Notes - Measures by Wave

Physical Health

• All measures in the ABCD protocol were revised to eliminate the use of binary gender classifications in the fall of 2020
• It needs to be clarified whether the COVID-19 Annual Form (Physical Health) and the COVID-19 Questionnaire (COVID-19 Substudy) are the same.

Brain Imaging

• "Yes/No" for imaging timepoints should be double-checked as PDFs of measures by wave broadly indicated that all brain imaging tests were done at every other yearly follow-up, but the specific tests that populate the rows of the table were taken from the online data dictionary where no information about the frequency of data collection was given.

Biospecimens

• In response to the COVID-19 pandemic, the ABCD study pivoted to remote testing in March of 2020. This affected the 2-, 3-, and 4-year follow-up assessments. The switch to remote testing did not allow for the collection of biospecimens.
• From NIMH Data Archive
  • Genomic data (short name: genomics_sample03) was collected from the following sources and was reported in ABCD Releases 2.0, 3.0, and 4.0. This data needs to be reconciled with that reported in the protocol by wave, which reported collection of DNA via oral fluids at baseline and DNA via blood every other year starting at baseline.
    • Whole blood; saliva, brain; urine; serum; plasma; CSF; IPS; Fibroblast; Neuronal Progenitor; skin biopsy; temporal cortex; lymphoblastoid cell line; semen; frontal cortex; parietal cortex; basal ganglia; placenta; hair; occipital visual cortex; cerebellum; spleen; stool; muscle; kidney; liver; heart; cord blood; nasal swab; DNA; RNA; breastmilk; buccal swab; oral cells; rectal swab; cervicovaginal swab

Mental Health

• Variables for the following diagnoses, obtained using the KSADS, are present in the data: Adjustment Disorder, Agoraphobia, Alcohol Use Disorder, Attention Deficit Hyperactivity Disorder, Autism Spectrum Disorders, Bipolar Disorders, Conduct Disorder, Disruptive Mood Dysregulation Disorder, Depressive Disorders, Drug Use Disorders, Eating Disorders, Generalized Anxiety Disorder, Obsessive Compulsive Disorder, Panic Disorder, Post-Traumatic Stress Disorder, Psychosis, Selective Mutism, Separation Anxiety, Social Anxiety, and Suicidality
• A switch was made to the KSADS 2.0 at the 3-year follow-up. This version introduced several changes
  • New diagnostic categories: schizophrenia, schizoaffective disorder, schizophreniform disorder, and autism spectrum disorder.
  • Branching algorithm to streamline supplement items.
  • Additional questions on the end of supplements that determine episode classifications.
  • Medication information, corresponding with diagnosis.
  • A more rigorous probe for hallucinations that requires hallucinatory-like experiences to occur during daily activity.
  • Moved paranoid ideation questions from the psychotic disorders screen to the supplement to minimize false positives.
  • Moved item about hypersexuality in the Bipolar Disorder screen to the supplement to minimize false positives.
  • A screen item pertaining to the duration of OCD-like symptoms was added, the obsessive thoughts about sex item was removed from the screen, and the phrasing of the initial OCD probe item was changed to minimize false positives.
  • Back button added.
• Need clarification about whether there is any overlap between the following: Adult Self-Report Survey, ASEBA Adult Self-Report (psychopathology), ASEBA Adult Behavior Checklist
• It needs to be clarified whether the "Difficulty in Emotion Regulation Scale" from the parent-report mental health section of the core study is the same as the "Difficulties in Emotion Regulation" from the emotion subsection of the social development substudy.

Neurocognition

• The Flanker Task was included under the NIH Toolbox on the PDFs of Measures by Wave but was listed as a separate cognitive task in the data dictionary.
• The RAVLT Delayed Recall task was listed as distinct in the PDFs of Measures by Wave, but not in the online data dictionary.

Substance Use

• Between March of 2020 and December of 2021 remote and hybrid testing in response to the COVID-19 pandemic required participants to complete some measures on their own devices. Remote performance was monitored via Zoom by research associates when feasible, and youth were asked to find private places to complete substance use measures, but this was not always possible. This reduction in privacy may affect responses.
• Discrepancies in when substance use measures were given to youth exist between the ABCD Study release notes and the ABCD Protocol by Wave fact sheets
  • Alcohol Expectancies Questionnaire (AEQ-AB)
    • Release notes: Annually from baseline to 3-year follow-up. Expected future assessment at 5-year and 7-year follow ups.
    • Protocol by wave: Annually from 1-year follow-up. (protocol by wave is correct)
  • Marijuana Expectancies (MEEQ-B)
    • Release notes: Annually from baseline to 3-year follow-up. Expected future assessments in 5-year and 7-year follow-ups.
    • Protocol by wave: Annually from 1-year follow-up. 1-3 year follow up, something weird with 4-year follow-up
  • Vaping Motives
    • Release notes: 2-year and 4-year follow-ups. Expected future assessment at 6-year follow-up.
    • Protocol by wave: 4- and 6-year follow-ups. (protocol by wave is correct just 3 and 4 year follow ups)
  • PhenX Peer Tolerance of Substance Use
    • Release notes: Administered annually baseline through 4-year follow-up.
    • Protocol by wave: Administered annually 1-year follow-up through 5-year follow-up. (1/2/3/4 follow up)
  • Cigarette Expectancies (ASCQ) (1/2/3/4)
    • Release notes: Baseline through 3-year follow-up, expected future assessments at 5-year and 7-year follow-up.
    • Protocol by wave: Annually since 1-year follow-up
  • Community Risk and Protective Factors (Parent) (baseline/1/2/3/4)
    • Release notes: Annually since 2-year follow-up
    • Protocol by wave: Annually since baseline.
  • Substance Use Density, Storage, and Exposure (Parent) (2/3/4)
    • Release notes: Annually since baseline
    • Protocol by wave: Annually since 2-year follow-up.

Culture & Environment

• Discrepancies in culture & environment measures between the ABCD study release notes and the ABCD protocol by wave fact sheets:
  • Pet Ownership (3/4)
    • Release notes: 3-year follow-up and 4-year follow-up.
    • Protocol by wave: 3-year follow-up only.
  • School Attendance of Youth & Grades (2/3)
    • Release notes: 2- and 3-year follow-up.
    • Protocol by wave: 2-, 3-, 4-, and 6-year follow up.
  • Parental Monitoring Survey (parent) (4)
    • Release notes: 4-year follow-up
    • Protocol by wave: 5-year follow-up

Core - Linked Data

• All information about linked data was taken from the ABCD online Data Dictionary
  • Source and measure abbreviation were noted the same way, making it hard to differentiate between the two as no definitions were given. All sources should be checked.
• In "Lead Risk" the online data dictionary noted that information on the "Percentage of individuals below -125 percent of poverty level" was taken. This number should be double checked for accuracy.
• All data collected through derived residential history contains variables for primary, secondary, and tertiary residential addresses.

Substudy - Linked Data

• All information about linked data was taken from the ABCD online Data Dictionary
• All data contains variables for addresses 1-5.
• For the Johns Hopkins University COVID-19 Prevalence linked dataset and the SafeGraph Social Distancing Metrics dataset, it was not clear which questionnaire the variable labels were referring to when stating that geocoded data was collected "0-6 days before from questionnaire dissemination date." It may be assumed that this is in reference to the COVID-19 questionnaire, which was administered at unspecified follow-ups through the COVID-19 substudy.

Notes - Coding Information

Physical Health

• Blood analyses run were taken from the online data dictionary. Blood (DNA) was listed as a distinct analysis in the PDFs of measures by wave but was not specifically mentioned in the data dictionary (hence why no table name was given).
  • Oral fluids (DNA) were also not listed in the data dictionary.

Gender & Sexuality

• All GISH items are coded under the table gish_p_gi, with the exception of the "GISH Male/Female Sum V2 Sum all male/female values" subscale total variables (gish_p_ss_m_sum2, gish_p_ss_f_sum2) which are coded under table mh_p_eatq (NDA 4.0: abcd_mph02) according to the ABCD Data Dictionary.

Substance Use

• Caffeine use questions were not included under the substance use phone interview in the online data dictionary.

Notes - Subscale Information

• For items without subscales, a general overview of variables that suggests ways that they may be sorted was given.
• The ABCD Data Dictionary should be used to view administrative (non-item) variables, precedents for validation, and to further explore total and subscale score calculation.
• Item variables were copied directly from the ABCD Data Dictionary.
• Subscale total variables were listed as they were provided in the Data Dictionary. A subscale without a total score variable indicates that one was not included in the Data Dictionary.
• A blank in any cell indicates that measure was mentioned in the ABCD Protocol by Wave PDFs, but could not be located in the Data Dictionary.
• If a scale included items that were not listed as counting toward a specific subscale score, the corresponding variables were listed under "Other Items". Administrative variables (e.g., those pertaining to administration or missing data) were not included here.
• Issues with variables in ABCD Data Dictionary
  • The same variables were referred to by different names when listed independently and listed for subscale calulation in the PPS and the GISH. The spelling of these item variables should be verified.
  • In, the data dictionary the notes for total severity score describes the variable as being the sum of all items assessing "How much did [this experience of psychosis] bother you" plus the "Did [this experience of psychosis] bother you?" subscale score. However, the variable label includes the sum of of all items assessing "How much did [this experience of psychosis] bother you" plus the number of questions asking "Did [this experience of psychosis] bother you?" that the child answered "no" to. It should be clarified whether the total of "no" responses or the total of "yes" responses should be used.
  • Both modified and unmodified variables exist for all BIS/BAS scores, with the exception of BAS Fun Seeking. It is unclear what the difference between these variables is, and both the modified and unmodified versions were included in the table.
• All CBCL, ASR, and ABCL subscale coding information was taken from source papers and scoring manuals, as the Data Dictionary did not include subscale scoring instructions for these scales. It should be confirmed whether the subscale items listed in these source materials align with the way subscale total scores were calculated in the ABCD Study.
  • The ABCD Data Dictionary simply referred to a "Stress" subscale. As literature pertaining specifically to this subscale could not be located, it was assumed that the Data Dictionary was referring to the Post-Traumatic Stress Disorder Subscale.
  • Certain items were missing from the version of the ABCD version of the CBCL that were specifically mentioned in subscale literature.
• All GISH items are coded under the table gish_p_gi, with the exception of the "GISH Male/Female Sum V2 Sum all male/female values" subscale total variables (gish_p_ss_m_sum2, gish_p_ss_f_sum2) which are coded under table mh_p_eatq (NDA 4.0: abcd_mph02) according to the ABCD Data Dictionary.
  • These subscale scores were not included under the Early Adolescent Temperament Questionnaire, and were instead added to the Gender Identity Scale row.
• It is unclear how the subscale score for the Surgency super scale is calulated on the Early Adolescent Temperament Questionnaire.
  • The variable label from the ABCD Data Dictionary reads: "Super Scale Surgency Sum Score mean (eatq_ss_surgency_sum_p of fear items (reverse scores), sum of shyness items (reverse scored). This subscale is assumed to be a sum in the table above for the sake of continuity, but this assumption should be confirmed.
