We, the Editors of BJPsych Open, have retracted the following article:

Davis et al, ‘Mental health in UK Biobank: development, implementation and results from an online questionnaire completed by 157 366 participants’, BJPsych Open, Volume 4, Issue 3, pp. 83–90 – Retracted.

In January 2019, the authors of this paper voluntarily submitted a corrigendum to the publisher which acknowledged that a data analysis coding error for Alcohol Use Disorders Identification Test (AUDIT) resulted in decreased alcohol use disorders prevalence and a resultant decrease in total psychiatric disorder prevalence.

An investigation by the Senior Editorial Board revealed that whilst this was a relatively minor coding error, it had led to a major and important change in the findings noted in the abstract, results section and associated comorbidity tables.

To ensure research integrity, the board decided that retraction of the original article with subsequent resubmission of a corrected paper would be the best course of action.

No institutional investigation or sanctioning by the Journal is indicated.

All of the authors agree to the retraction.

We discuss more fully the issues and our response to them in an accompanying editorial (Kaufman et al., 2019).
