OToPS/ABCD/Mental Health

Notes:

• 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.

Notes:

• 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.
  • 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.
• 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.
