In their fifth meeting at the Vrije Universiteit Amsterdam in 2017 (5th WCRI), the World Conference on Research Integrity (WCRI) adopted the Amsterdam Agenda (AA). The AA is a policy statement stipulating six key elements that researchers doing research on aspects of research integrity preferably should use when preregistering their empirical research projects (https://www.wcrif.org/guidance/amsterdam-agenda). The applicants of this submission form performed an ad hoc study in 2019 using data supplied by paper and poster presenters of the 6th WCRI in Hong Kong, 2019, to find out to which degree researchers had pre-registered the study they were going to present at the 6th WCRI, using either the recommendations of the AA or other recommendations. The first applicant (Sijtsma) presented the results in the final plenary session of 6th WCRI. The pilot study showed that 19% of the 308 presenters had preregistered their research. Of the 56 usable cases, less than half of them provided information on one or more of the six key elements of the AA. Others provided information that invalidated their data, such as an uninformative URL. There was no discernable difference between qualitative and quantitative research. We published our results in the journal Research Integrity and Peer Review (Sijtsma et al., 2021).Our study suffered from two limitations. First, we did no plan our research a priori but used the raw data the 6th WCRI organizers made available on an ad hoc basis. These raw data came from the information 6th WCRI participants provided while registering and submitting their paper and poster proposals. This implied that we had to work with data that were not collected with our study questions in mind. Second, given highly restrictive time limits, the WCRI organizers were unable to receive participants’ consent for using their data once we planned our research, and we were unable to receive timely consent of an ethics committee and to preregister our research.The present proposal continues the 2019 research, but improves both its content and fully obeys procedural requirements. That is, we plan the data collection a priori, ask participants for their consent to use their anonymized data, request consent by an ethics committee, and pre-register the study.
