Academic life is not easy, especially for new researchers. The notion that disembodied inventions lead to impact rather than scientists' initiative and actions requires robust challenge. ^{Reference Eisenstein1} Younger researchers struggle to secure their first research grants, although the funding success rates are higher in Germany and from UK research councils than from EU research councils and the NIH in the USA. ^{Reference Maher and Sureda Anfres2} Older scientists appear to be more successful at securing research funding from the MRC and NIH. ^{Reference Maher and Sureda Anfres2} Yet, on average only 38% of research time is spent on delivering research, with more time being consumed by administration and budget management, and 20% devoted to teaching. Teaching responsibilities are increasingly important to ensure that young people are equipped for the workforce, in science and other areas, and that there is integration of research expertise with teaching and practice to maximise impact on society. Teaching is also perceived to yield a better return on investment, compared with research grants that seem never to fully meet the costs of undertaking research. Therefore, most universities now see their core business as teaching. Integration of research and teaching is recognised in the UK-based Research Excellence Framework and in the forthcoming Teaching Excellence Framework; indeed, teaching on the findings of research and sharing the knowledge are considered important evidence of impact in both frameworks. Scientific journal production, editorial roles and peer review of original research are essential tasks of an academic community, but regrettably these are less well recognised in assessments of academic performance, in favour of more conventional metrics including published articles in high-impact journals, research income, and evidence of direct effects on practice, policy or research. The BJPsych recognises peer reviewers by offering annual certificates of performance (personalised certificates can be downloaded from the website after logging in), and editorial board members will now also receive metric-based feedback so that contributions may be better recognised.

The history of psychiatry is full of examples of inventions in practice, and this process is elegantly captured by Beveridge's balanced but critical commentary on historical failures and successes. ^{Reference Beveridge3} Freeman argued in his review of Thomas Bewley's book that the British Journal of Psychiatry was critical in the formation and survival of the Royal College of Psychiatrists (formerly called the Medico-Psychological Association). ^{Reference Freeman4} This sort of impact over 150 years might be difficult to recognise and quantify. The BJPsych was originally founded in 1853 as the Asylum Journal and was known as the Journal of Mental Science from 1858 to 1963. The archive of content between 1855 and 2000 is available online as a treasure trove for historical researchers. Many of the most important and definitive papers with impact on practice, research and policy have appeared in the Journal. The impact factor has grown gradually over the years and is currently 7.06. I, along with members of the editorial board, am deliberating on new ways of assessing impact. Given we that we are a research journal with a broad readership, published by a membership society that seeks to improve the practice of psychiatry and mental healthcare, perhaps the number of citations for the journal is more telling. For example, among the top ten ranked on impact factor, BJPsych has the third highest number of citations, and outside North American journals, the highest number. We also reach out to over 17 000 readers who are members of the Royal College of Psychiatrists, along with other mental health experts from all disciplines, as well as scientists, commissioners and policy makers. Impact includes the way specific policies or practices or treatment guidelines are changed because of published research. And the BJPsych impacts not only readers, but also the authors, reviewers and editorial board members – among them senior academic leaders from higher education institutions around the world – all engaged in the disciplined scholarship intrinsic to writing, assessing and reviewing research papers. The youngest in the BJPsych family of journals – BJPsych Open – is too new to have a formal impact factor, but has already achieved popularity by its flexible and rapid publication of a wide range of high-quality research, made open access both on its own website and in PubMed Central. We have adopted social media-based measures of impact, but what else might we capture in alternative scientific measures of impact?
