London now shuns journal-based metrics in staff assessment; it relies more on peer judgement of research quality. At Mahidol University in Bangkok, Thailand, all staff sign the university's code of good governance, agreeing to uphold integrity, impartiality and social responsibility, for example. These are just three of dozens of efforts we found when investigating how institutions worldwide are working to improve research integrity. They form part of our long-term study on this topic, a project that is funded by the European Commission (see Table S2 in Supplementary information for more examples).

To foster research integrity (RI), it is necessary to address the institutional and system-of-science factors that influence researchers’ behavior. Consequently, research performing and research funding organizations (RPOs and RFOs) could develop comprehensive RI policies outlining the concrete steps they will take to foster RI. So far, there is no consensus on which topics are important to address in RI policies. Therefore, we conducted a three round Delphi survey study to explore which RI topics to address in institutional RI policies by seeking consensus from research policy experts and institutional leaders. A total of 68 RPO and 52 RFO experts, representing different disciplines, countries and genders, completed one, two or all rounds of the study. There was consensus among the experts on the importance of 12 RI topics for RPOs and 11 for RFOs. The topics that ranked highest for RPOs concerned education and training, supervision and mentoring, dealing with RI breaches, and supporting a responsible research process (e.g. through quality assurance). The highest ranked RFO topics concerned dealing with breaches of RI, conflicts of interest, and setting expectations on RPOs (e.g. about educating researchers about RI). Together with the research policy experts and institutional leaders, we developed a comprehensive overview of topics important for inclusion in the RI policies of RPOs and RFOs. The topics reflect preference for a preventative approach to RI, coupled with procedures for dealing with RI breaches. RPOs and RFOs should address each of these topics in order to support researchers in conducting responsible research.

Current research integrity (RI) guideline development methods can miss diverging perspectives, but these are crucial for accounting for stakeholders’ needs across countries and disciplines. Co-creation could be a promising RI guideline development method. We conducted interviews with 22 stakeholders taking part in an RI guideline co-creation project. Our results indicate that stakeholders believe that co-creation stimulates the expression of diverse perspectives. Furthermore, they say that co-creation is powerful in engaging stakeholders, and increasing support for the guidelines. Our interviewees expressed that various features of co-creation contribute towards evoking a broad range of valuable ideas. Co-creation was deemed valuable for producing a rich harvest, including reaching agreement on crucial guideline elements, and for understanding important nuances. Our interviewees supported the use of a multi-stage co-creation methodology for the initial phases of RI guideline development. Based on these findings, we recommend guideline developers to consider using co-creation to bring together diverse perspectives.

Research integrity (RI) is a continuously developing concept, and increasing emphasis is put on creating RI promotion practices. This study aimed to map the existing RI guidance documents at research performing organisations (RPOs) and research funding organisations (RFOs). A search of bibliographic databases and grey literature sources was performed, and retrieved documents were screened for eligibility. The search of bibliographical databases and reference lists of selected articles identified a total of 92 documents while the search of grey literature sources identified 118 documents for analysis. The retrieved documents were analysed based on their geographical origin, research field and organisational origin (RPO or RFO) of RI practices, types of guidance presented in them, and target groups to which RI practices are directed. Most of the identified practices were developed for research in general, and are applicable to all research fields (n = 117) and medical sciences (n = 78). They were mostly written in the form of guidelines (n = 136) and targeted researchers (n = 167). A comprehensive search of the existing RI promotion practices showed that initiatives mostly come from RPOs while only a few RI practices originate from RFOs. This study showed that more RI guidance documents are needed for natural sciences, social sciences, and humanities since only a small number of documents was developed specifically for these research fields. The explored documents and the gaps in knowledge identified in this study can be used for further development of RI promotion practices in RPOs and RFOs.
