Supplementary material for: Testing the Usability of the Psychological Research Preregistration-Quantitative (PRP-QUANT) Template (Preprint)

This is the electronic supplementary material for the preprint: Testing the Usability of the Psychological Research Preregistration-Quantitative (PRP-QUANT) Template The Psychological Research Preregistration-Quantitative (PRP-QUANT) Template provides researchers with a comprehensive list of elements to consider when planning a psychological study. We assessed its usability and researchers’ intention to use it. We conducted a usability test (study 1) and surveyed researchers who submitted or reviewed a preregistration created with the template (study 2, authors: N = 19, reviewers: N = 29) regarding their impression of the template. For the usability test, we recruited participants via the mailing lists of the German Psychological Society, the American Psychological Association, and the British Psychological Society, and social media. Participants answered selected template and web probing items and provided an overall rating (N = 88). Based on the Unified Theory of Acceptance and Use of Technology (UTAUT), we expected that the intention to use the template is influenced by performance expectancy (moderated by age), effort expectancy (moderated by age and experience), and social influence (moderated by age, experience, and voluntariness, N = 60). The results suggest that the PRP-QUANT Template is suitable for different research areas within psychology, is evaluated as effective, and perceived positively. Performance expectancy and all predictors combined significantly predicted researchers’ intention to use the template. Appendix A. Plain language summary. A plain language summary is provided to increase the accessibility of these research findings to a wider audience. It is available in English and German. Appendix B. Research areas. Research topics indicated by the sample of study 1 are displayed in a table. Appendix C. Overview of survey items. The items of both study 1 and study 2 are presented. If they were derived from other studies, the original items as well as references are given. Appendix D. Screen recording. This screen recording shows an example walkthrough of study 1, for a participant assigned to condition 1. Appendix E. Questionnaire. The questionnaire of study 1 is displayed in a PDF for easy inspection, separately for all conditions. Please note that filters do not work in this view, i.e., all items are displayed. Appendix F. Coding scheme (revised). The coding scheme used to code the fit of participants’ responses to the template items in study 1 is displayed. Appendix G. Overview of template response fit. This table shows the fit of responses given to the template items in study 1. Appendix H. What would participants add, change, or remove about the template items. A table summarises all comments on what participants would add, change, or remove about the template items. Appendix I. Web probing. The results of the web probing items are reported here. unknown unknown
