In April 2023, Psychosomatic Medicine, now renamed Biopsychosocial Science and Medicine, introduced registered reports as a new article format. Registered reports are a type of scientific article in which the research methods and proposed analyses are preregistered and peer-reviewed before the data are collected or analyzed. We were excited to be joining a growing number of journals internationally to offer this format and to be aligning with the Behavioral Medicine Research Council's statement on open science, recognizing the value of publishing registered reports in our field. Recent work has shown that there is a 2-year lag between journals adopting registered reports and publishing their first registered report. Therefore, right in line with this timetable, we are delighted to be publishing our first full registered report article in this first issue that bears the Journal's new name. This article is noteworthy for several reasons, not least because the findings make an important scientific contribution to the broader early life adversity literature but also because the article applies the registered report format to secondary data analyses. We hope that you, our readership, feel inspired to give the registered report approach a chance, whether it is for primary or secondary data collection approaches, and that you send your first, or next Stage 1 registered report to Biopsychosocial Science and Medicine.
