In light of various inquiries we’ve received from authors, we’d like to clarify our open data policy. The full policy reads as follows:

PTAD encourages authors to make the raw data and the code (e.g., R, Stata, or SPSS code with detailed explanations allowing it to be reviewed) or the converted score data underlying the main findings reported in the article available to the public (open data). Exceptions may be made (e.g., for reasons of data security or confidentiality) provided the reasons are set out during submission of the manuscript. It is recommended that authors place any open data and code in a repository and provide the URL(s) during manuscript submission in Editorial Manager. With the acceptance of a manuscript a permanent URL or DOI pointing to a file(s) located in a public repository should be provided. Preferred repositories for PTAD are PsychArchives (run by a public open science institute for psychology; for detailed instructions see and OSF. Other repositories may also be suitable as long as DOIs or accession numbers are provided and the data are at least as open as CC/BY (for a list of repositories see

About the journal

Psychological Test Adaptation and Development (PTAD) is the official open access journal of the European Association of Psychological Assessment. PTAD is the first open access, peer-reviewed journal publishing papers which present the adaptation of tests to specific (e.g., cultural) needs, test translations, or the development of existing measures. Moreover, the focus will be on the empirical testing of the psychometric quality of these measures. The journal will provide a paper template, and registered reports are strongly encouraged.

The submission portal is now live. A generous APC waiver program is available.

Psychological Test Adaption and Development – A New Beginning
Matthias Ziegler
Humboldt-Universität zu Berlin, Germany

When I took over as editor for the European Journal of Psychological Assessment (EJPA) in 2013, one of the first editorial decisions I made was to change the journal’s policy with regard to test translations. Basically, this meant that all papers which presented a translation without evidence for measurement invariance with the original measure or additional validity information were desk-rejected. Back then I felt that this was a necessary step to further develop the journal and the “brand” EJPA. While it proved to be really good for the journal, I have to admit that I had not taken into consideration its impact on the field of assessment in Europe. The problem I had underestimated is that many projects in the area of assessment really do start with the translation or adaptation of an existing measure – and without a reputable journal prepared to publish the fruits of such work, researchers found it increasingly hard to publish internationally. Ever since, the echo I get from colleagues reflects this Janus-faced success. I was even told by some colleagues that working in the assessment area became less attractive as a result! This is something that did not go down easily with me, I must admit. Similar unease caused the European Association of Psychological Assessment (EAPA) to start looking for options to fill the gap that we had unintentionally created.

Fortunately, we found a publisher who was enthusiastic about our ideas, recognized the gap and needs that we had identified, and helped us towards a new beginning with the launch of Psychological Test Adaptation and Development (PTAD), whose founding editor I now have the honor to be. It is my pleasure to embark on this endeavor with an expert cast of associate editors: Tom Booth (University of Edinburgh, UK), Irena Burić (University of Zadar, Croatia), Miguel Angel Carrasco (Universidad Nacional de Educación a Distancia, Spain), Marjolein Fokkema (Leiden University, The Netherlands), Samuel Greiff (University of Luxembourg, Luxembourg), Nelson Hauck-Filho (Universidade São Francisco, Brazil), Kai T. Horstmann (Humboldt University Berlin, Germany), Lena Lämmle (Medical School Hamburg, Germany), René Proyer (Martin-Luther-University Halle-Wittenberg, Germany), John Rauthmann (Universität zu Lübeck, Germany), Jennifer Tackett (Northwestern University, Evanston, IL, USA), and Michele Vecchione (Sapienza Universita di Roma, Italy).
PTAD is the official open-access journal of the European Association of Psychological Assessment. As such it fully embraces the concepts of open science. One of the consequences of this is that we welcome and encourage submissions in the form of Registered Reports. In general, PTAD is meant to be the outlet for research papers that portray the process of a test adaptation, such as a translation. In addition, papers reporting on test developments (e.g., from a trait to a state measure) are also very welcome. It should be noted here that, in the initial years, there will be a generous APC waiver program for authors wishing to publish in the journal – further information can be found below. So a lack of funds for publication fees is no reason to shy away from a submission.

As well as providing an outlet for translations and adaptions (and thereby healing a self-inflicted wound!), another primary aim of PTAD is to improve the quality of psychological assessment in general by providing test users with quick-to-understand papers showcasing the psychometric qualities of the score(s) obtained using the measures that are described. PTAD also aims to be an attractive journal for test authors. In order to achieve these two goals, we ask authors to stick to relatively strict and detailed guidelines for submissions – which I go into in a separate article. While some may think this is intervening in the creative writing process, it will also be of advantage for our authors. One advantage is that review times can be very short because each paper follows similar guidelines on structure and logic. In combination with the opportunity to submit a registered report, authors can thus obtain expert feedback within a short period of time – feedback that will result in improved quality of the papers in the journal. The guidelines also serve the function of helping test authors plan and conduct their studies, integrating as they do current quality standards such as the APA Standards (AERA, APA, & NMCE, 2014) or EFPA guidelines (EFPA Board of Assessment, 2013). As is the case in the European Journal of Psychological Assessment, PTAD enforces the “ABC of test construction” (Ziegler, 2014) which encapsulates the essence of these quality standards.
As I mentioned, a separate document entitled “Psychological Test Adaption and Development – How Papers Are Structured and Why” goes into much more detail and explains the structure and “template” that we have developed for papers in PTAD. Please do read it!

All that remains for me to say now is that I am looking forward immensely to the start of the new journal – and to reading YOUR paper!

For authors

Article publication charges (APCs)

In order to cover the costs of publishing the journal, including those of manuscript submission and peer review management, journal production, online hosting and archiving, liaison with abstracting and indexing services, as well as online distribution and data feeds to libraries, discovery services, content aggregators, and other information services, an article publication charge (APC) must be paid.

Hogrefe Publishing is currently offering a generous waiver program for eligible authors. Eligible papers shall include papers by authors who do not have access to publication fee grants or funding, papers by authors who are not employed or funded by commercial organizations, and other papers as may from time to time be agreed by Hogrefe.
