Several market research studies have evaluated peer review in recent years. A goal of the present research, commissioned by PRE, is to extend those findings to provide insight into the indicators of quality of peer review. In January, 2016 Wicherts proposed that transparency of the peer review process may be seen as an indicator of the quality of peer review. By testing a questionnaire tool with several audiences with different methods, he concludes that the tool has promising reliability and validity in assessing transparency of the peer-review process as an indicator of peer-review quality. In this market research, we ask respondents to rate the helpfulness of several criteria based in part on Wicherts’ 14-item tool which rates the transparency of a journal’s peer review process, regardless of peer review model, open or blinded, pre-publication or post-publication.
