These trainings were co-produced with members of the public and research team professionals for the Mental Health Research for All project.•Our co-production process lasted several months from October 2023-March 2024. We co-delivered the training with several of the co-producers. Due to interest, we delivered it a second time in July 2024 with improvements based on the first version of the training. We have included both versions of the training in this document, with the more recent version first.
