Health Psychology Bulletin (HPB) is a disruptive open access journal that encourages full disclosure and explicitly welcomes both direct and conceptual replications, null findings, reports of failed manipulations, as well as empirical papers and reviews. HPB is an initiative of the EHPS and community oriented open access publisher Ubiquity Press (UP). By launching this journal, the EHPS and UP hope to ultimately contribute to better mental and physical health all over the world. The journal will have a full disclosure policy, strongly recommending authors to make public not only their data, but also everything other researchers need to replicate their study and analyses.

Ethical responsibility
HPB aims to publish all research, based on the view that once data have been collected from participants, it is the ethical responsibility of the scientific community to publish those data. Therefore, HPB will even publish flawed studies, provided that the flaws are clearly explained and the conclusions that are drawn are consistent with the data.

Transparent, honest and integer
For all research, HPB papers will frankly discuss what went wrong and which changes were made along the way. The journal will focus on the lessons that can be learned instead of selling a study, design, or specific findings. This radically different policy means that HPB will strive to realise a shift from the traditional, competitive model of science to a more collaborative model, where research papers become transparent, honest, and integer documentations of a scientific endeavour.
