This repository converts the ABCD data dictionary from ABCD Study Dictionary to the ReproSchema format. This conversion serves reproducibility purposes, allowing the ABCD data dictionary to be tracked over time. The repository will be updated every time the ABCD data dictionary changes, with each version appropriately tagged for easy reference. Our conversion does not include the "Imaging" part of the dictionary. The first data dictionary version is not REDCap; later versions will be.

• abcd_data_dict_v[version].csv: CSV file of the ABCD data dictionary downloaded from the ABCD Study Dictionary website
• core folder: The core study of ABCD in ReproSchema format, generated by abcd2reproschema.py
• substudy folder: The substudy of ABCD in ReproSchema format, generated by abcd2reproschema.py
• abcd2reproschema.py: The Python script converts the ABCD csv file into reproschema format.

Both core and substudy are research protocols containing different activities (questionnaires), where each activity has its questions represented as items. For more information on ReproSchema, please read this documentation.

To reproduce each tagged version, run the following command:

python abcd2reproschema.py --file_path abcd_data_dict_v[version].csv --version version

For example:

python abcd2reproschema.py --file_path abcd_data_dict_v010.csv --version 0.1.0

We did the following steps to tag a version:

1. Commit changes to the repository:

git add .
git commit -m "Update ABCD data dictionary to version [new_version]"

2. Create a new tag for the version:

git tag -a v[new_version] -m "ABCD data dictionary version [new_version]"

3. Push the tags to the remote repository:

git push origin --tags
