Authorship Policy

Authorship Policy for ADHD Working Group of the Psychiatric Genomics Consortium 

Authorship guidelines for our working group stem from the 2014 MOU and were most recently updated for clarity in 2025.

1. On papers primarily based on our collaborative data set (e.g. new meta-analyses, machine learning analyses), all consortium members are co-authors, and the consortium name (ADHD Working Group of the Psychiatric Genomics Consortium; PGC) is placed after the senior authors (depending on journal guidelines). All named authors should see, comment, and agree to the submission of the paper prior to submission. Authors can actively opt out from inclusion in the authorship list, and any co-authors who do not respond within two weeks to requests to comment on a manuscript or to provide information requested by journals can be removed from the authorship to be placed in the Acknowledgement section.

2. For analyses where the individual genotype data from our working group are used in a secondary manner, e.g. to replicate results from non-consortium data, members of the primary analysis and writing groups are the only named authors. All others are listed under the consortium name, which is given between first and last authors. The authors listed under the consortium name will appear in PubMed. All named and footnoted authors should see, comment and agree to the submission of the paper prior to submission. Authors can actively opt out from inclusion in the authorship list, and any co-authors who do not respond within two weeks to requests to comment on a manuscript or to requests from journals can be removed from the authorship to be placed in the Acknowledgement section.

3. For the use of only summary stats from our working group, which are freely available, the ADHD Working Group of the PGC is acknowledged in the Acknowledgement section, and the manuscript from which the summary stats are derived is cited; the members will not be listed in PubMed.

4. For the use of NEW summary stats from our working group, which are not yet available publicly, a secondary analysis proposal will be required to access these data and submission of secondary analyses for publication must wait until the primary manuscript from which the summary stats are derived has been accepted for publication; as with point 3 above, the ADHD Working Group of the PGC is acknowledged in the Acknowledgement section, the primary manuscript must be cited and the members will not be listed in PubMed. Presentations of these data prior to the main publication need to include a disclaimer that these are preliminary data. 

Wherever possible, the manuscript should be posted on a pre-print server (e.g. bioRxiv/medRxiv) upon submission to a journal (at the latest).

GWAS summary statistics for all SNPs in the primary analyses performed in the papers will be posted on the PGC downloads webpage when the manuscript appears on bioRxiv/medRxiv.

We recognize that the particular requirements of individual journals might require changes in specific aspects. Should that occur, the corresponding author of the paper in question will proactively set up an email exchange with the representatives of the ADHD Working Group of the PGC to arrive at a solution.
