Yesterday I published a short blog in response to Dorothy Bishop’s blog who questioned some of the editorial practices of journals that I regularly published in. As a consequence of Dorothy Bishop’s blog, I was contacted by Jack Grove, a journalist at the Times Higher Education on late Friday afternoon (July 17). Mr. Grove wrote:
“I am a journalist in London who writes on research integrity issues. I’m following up a recent blog by an Oxford University professor who has called attention to what sees as questionable publication practices in some of the journals that you regularly write in, namely to do with your research output… The blog raises some interesting questions about your relationship with these journals as so much of your work appears in them. While I can see that they are relevant to your research area, I’m sure you can appreciate why this pattern of publication is concerning.
Professor Bishop also mentions your publication rate which does seem rather astonishing. Looking at your personal web page it seems you have published some 113 articles so far this year – which is more than one every two days, and more than 1,700 pieces in your career so far, which raises some questions about how much input you are actually having on these co-authored publications. This has been raised a few times before, with some critics saying that, with self-citation, it’s a handy way to inflate your h-index. If you could respond to these concerns, I would be much obliged as I intend to write something about this next week”
Within five minutes of receiving the email I wrote back to Mr. Grove:
“I would be delighted to talk to you and I can send you every draft of every single article I have co-written this year (and most years over the last decade) because I keep every version of every paper with every track change I have ever made. I’ve done this for years for eventualities like this because some individuals simply don’t believe that I have co-authored all the papers I have published. Attached is the response that has been sent to Dr. Bishop by the Journal of Behavioral Addiction. I’m not sure how other journals are going to respond but I would imagine it would be along the same lines as this. Happy to talk now, over the weekend, or at you convenience. My home number is [supplied my number]. I would be delighted to talk to you about how I do what I do. I have contributed to every single paper I have ever published and can prove it”.
Mr. Grove emailed back to say he would like to chat to me Monday afternoon (July 20). On the morning of July 20, I emailed Mr. Grove to ask him what time he would like to speak to me that afternoon. He didn’t reply and he didn’t ring me that afternoon. In the meantime, on Friday evening (July 17, 2020), I emailed all the people that I have published with this year and wrote:
“Today I have been approached by a journalist (Jack Grove) at the Times Higher Education here in the UK about all the articles I have co-authored and published this year so far (over 100) – see his email below. His email claims that the number of papers I have co-published this year “raises some questions about how much input you are actually having on these co-authored publications”. I would be very grateful if you could confirm to Jack that my co-authorships on our papers were as a direct result of intellectually and physically writing and contributing to each of the papers I have co-published with you. His email appears to be implying that my name is just being put on papers without any contribution from me which I find very hurtful and is questioning my integrity. As you probably all know, I keep every version of every paper that I contribute to and am happy to share these with the journalist. I’m sorry to have to do this but I would be very grateful if you could simply confirm that I materially contributed to the publication(s) we co-authored. Please don’t reply to everyone, just to the journalist and myself will suffice”.
Since writing my email, almost all the people I contacted have emailed Mr. Grove. Here are some excerpts of the emails that Mr. Grove has received. They demonstrate that I materially and intellectually contributed to every paper I have co-authored and published this year.
Xavi Carbonell (Spain)
“I have been working with Mark in the last few years. I am in debt with him as are some of my doctoral students (Marta Beranuy, Alexandra Rodríguez and Héctor Fuster). Mark has been helping a lot, been always available and making substantial contributions to our research and to the papers. Mark also was the tutor of three-month international research stays of Marta Beranuy and Alexandra Rodríguez and one short research stay of myself. I could provide you with some of the manuscripts that we have been working on where you can see (visible changes in the word document) the suggestions and changes provided by Mark in the preliminary versions of the manuscript. Mark is a tireless and efficient worker and I am very proud to know him and very grateful to him”.
Vasileios Stavropoulos (Australia)
“In all the papers that we have worked together [Mark Griffiths] had significant intellectual contribution in at least three different ways: (i) contribution to the research idea conception, before data collection/research implementation, (ii) interpretation of the findings, and (iii) review and final edit of the final document submitted. The reason that I have initially aimed to collaborate with [him 4 years ago] had to do with his international reputation and my desire to gain visibility for my work. The reasons that I now continue working with him are: (a) his thoroughness; (b) his speed in delivering outcome; (c) his collegiality; and (d) his honesty. I can also confirm that in every single paper we have worked together, the title page of the initial submission to the journal has always included the specific authors’ contributions. I can also provide all his thoroughly edited (with track changes) documents, and emails for every research submission we have had together”.
Mustafa Savci (Turkey)
“Dr. Griffiths made unique contributions to my studies. In the papers we published, [his] contribution was not less than mine. I have always appreciated [his] contributions in papers we co-author. I want you to know that I have witnessed that the allegations were unfounded”.
William Van Gordon (UK)
“Sorry to hear about these allegations. [Dr. Griffiths] certainly made meaningful and material contributions to papers that we wrote together”.
Pawel Atroszko (Poland)
“I write in relation to your e-mail to Prof. Mark D. Griffiths concerning his prolific academic output in terms of published scientific papers, and doubts raised by Professor Bishop’s piece. Since 2015, I have written several papers with Prof. Mark D. Griffiths…I would like to confirm that his co-authorships on our papers were as a direct result of intellectually and physically writing and contributing to each of the papers we have co-published. I believe the rate of publishing of Prof. Griffiths is a reflection of his extraordinary work ethic and expertise in the field of behavioral addictions. He can be considered among the most important researchers worldwide in establishing the field in recent decades and dynamically moving it forward, and has been publishing on the issues related to compulsive behaviors (to my knowledge) since the late 1980s when the field of behavioral addictions was still virtually non-existent. From this point of view, he embodies the history of this field and has an unparalleled overview of its development, and deep understanding of its issues. Taking into account my knowledge of the behavioral addictions field and my experiences of collaborating with Prof. Griffiths, I would conclude that his expertise matched with inexhaustible engagement in moving the field forward in development, as well as openness and willingness to collaborate best explain his prolific publishing. In relation to Professor Bishop’s piece, she wrote on his blog: ‘Neither IJMHA nor JBA publishes the dates of submission and acceptance of articles, and so it is not possible to evaluate this concern’. I would like to point that this statement is not true and all of my papers with Prof. Mark D. Griffiths published in JBA from the first one in 2015 to the most recent one were peer reviewed, have submission dates and acceptance dates printed on the first page of the paper, and Prof. Griffiths has actively participated in the process of correcting papers after suggestions of the reviewers. In the case of all of my papers with Prof. Griffiths, he was engaged in the process of writing them from clarification of the initial idea till final corrections after reviews”.
Daria Kuss (UK)
“Professor Mark Griffiths is a leader in the field of behavioural addictions due to his unmatched set of skills, his ability to communicate ideas clearly and flexibly to different audiences, his unparalleled work ethic and dedication. With his body of work and grasp of novel ideas, he has inspired numerous researchers across the world, including myself. Mark and I have co-authored dozens of papers over the last decade, including peer-reviewed publications, various reports, papers in the trade press and the news media, book chapters and a book. He has had a significant intellectual contribution to all of our co-authored publications, including developing the original ideas, writing the papers, editing them across multiple iterations, and revising them following reviewers’ and editors’ comments. He has furthermore contributed his invaluable expertise to the publication process of our co-authored work, including evaluations of particular journals, and supporting the work’s impact and visibility across various channels. Mark has always been a thoughtful, honest and responsive mentor whose expertise, loyalty and integrity are second to none. I am very grateful for his indispensable contributions and his steadfast mentorship across the many years we have had the pleasure to work together”
Marta Beranuy Fargues (Spain)
“I am writing to confirm that [Dr. Griffiths] made a considerable contribution to the article that we have published together this year”.
Doris Malischnig (Austria)
“I can only say that there is no one who contributed so much to the published articles and from whom I have learned more than from him. He actively contributed to every paper, rewrote, supplemented, improved, and after the submission helped me to answer the questions of the reviewers correctly. For example for our paper, which was published in January (2020), I have more than 100 emails that we exchanged. This paper has been radically revised twice, it took us 3 years to get the paper published!! He accompanied the process so intensively, answered questions and suggested and supplemented evaluations, and motivated me to keep to it. I even asked him to be the first author on the paper. His input was significantly larger than mine. He refused! Without Mark Griffiths, neither the scientific knowledge nor the practical impact would be where they are today. For that he would actually have to be knighted. He works day and night, namely to help us and science that the world looks better for problem gamblers or other addicts and their families. If you need evidence, I have saved all emails and his related work on the articles we published together, because it helps me to learn from them afterwards”.
Supakyada Sapthiang (UK)
“I’m surprised to see this blog is by an Oxford professor as its highly speculative. You made substantial intellectual contributions to my papers for which I am very grateful”
Alexandra Torres-Roriguez (Spain)
“I would confirm that all of authorships of Dr. Mark Griffiths in our papers were correct. Dr. Mark was my thesis co-director, and I attended NTU when I was doing my International PhD. We did more than ten versions regarding the papers. Not only that, he taught me important aspects of the publications, he provided complete sections, he made substantial and key contributions, and he stayed with me throughout the process involved. [Dr. Griffiths] has been one of my best and most dedicated teachers, from whom I have learned a lot. Always willing to help me kindly with my thesis and with anything related to my research career”
Christian Montag (Germany)
“I can tell you my experience from one paper, I published this week with Dr. Mark Griffiths [in ‘Frontiers in Psychology’] Dr. Cornelia Sindermann and I led with this paper, but I can assure you that all co-authors substantially worked over the paper and gave important intellectual input. I liked this cooperation, because the input was very valuable and the work-pace rapid”.
Hibai Lopez-Gonzalez (Spain)
“[Dr. Griffiths] was my mentor during my two-year (2016-2018) postdoctoral research fellowship at Nottingham Trent University. We had one-hour meetings almost every week, in which we discussed my research ideas and prospective papers. He provided general guidance most of the time but not once he refused to get his hands dirty and engage with monotonous data analysis…We have co-authored 22 refereed papers together, if my calculations are not mistaken. He would always offer a critical assessment of the manuscripts I sign as leading author, including dozens of editing tips and modifications as track changes to the word documents I share with him. The turnaround time is usually 12-48 hours, including holiday periods and weekends. In many of those times [Dr. Griffiths] is abroad for work but his response time is usually unaffected by it. This has also been the case in one occasion in which he was hospitalised. I would like to add that I have never published a paper with his name on it without him contributing to it. I think I’m not alone in wondering how Mark does the trick. I don’t have the answer to this question, but I guess a combination of neurodivergence (for example, for most of his life he slept 3 hours a night) and perfectionism/obsessiveness (he would edit every single comma, capital letter, italic and space from the reference list) could work as a preliminary hypothesis”.
Colin O’Gara (Ireland)
“There is no question that [Dr. Griffiths] has contributed materially to our recent publications in the area of behavioural addictions in Irish populations. I first met Mark at a conference in 2012 in Dublin and always wanted to collaborate with him. He is an excellent colleague and we are immensely grateful for his time and generous contributions. We would be very much hoping for Mark’s continued input in future”.
Amir Pakpour (Iran)
“I confirm that my collaborations with [Dr. Griffiths] is meaningful. [Dr. Griffiths] collaborates with me in my works in computational framework, drafting manuscripts, results interpretations, and revising [papers] critically for important intellectual content”.
Md. Abdullah Mamun (Bangladesh)
“I am just writing to confirm that Professor Griffiths made major written and intellectual contributions to all the papers that I have co-authored with him this year (and last year). Whenever I send him a draft of a paper he typically works on three or four drafts before submission. I have learned so much from him over the past three years and he has helped rise my research profile in Bangladesh enormously”.
Tzipi Buchman-Wildbaum (Israel)
“I confirm that Mark Griffiths had a significant contribution to the publications we co-authored. Mark had meaningful contribution to the writing and editing of the papers. He also provided supervision, guidance, and professional feedback from his extensive theoretical knowledge in the field of mental health and psychopathologies. He was involved and devoted during the whole publication process and I’m grateful for his help and involvement in my work.”
Kamrul Hsan (Bangladesh)
“I am writing to you about Mark Griffiths’ co-authorship on our papers. I would like to inform you that Mark Griffiths was a co-author on some of our papers…He contributed to [the papers] both intellectually and physically writing, and manuscript preparation. He is a very hard working researcher and supportive to young researchers”.
Niklas Hopfgartner (Austria)
“I can confirm that Mark always provides valuable input in our research / papers, both through physical writing and discussing ideas / methods / results”.
Tyrone Burleigh (UK)
“I would like to share my experience with [Dr. Griffiths] as my co-author. The number of articles I have published is relatively small. However, as an early career researcher Mark’s input on my papers has been an invaluable contribution. In my experience, he has always added a layer of expertise and critical insight into my papers (both physically and intellectually), and his contribution has been anything but minimal. Mark is an extremely dedicated researcher and he has always gone that extra mile to help me in my work. I have seen no faults in his work ethic or integrity when I have had the pleasure of collaborating with him”.
Elizabeth Killick (UK)
“I have co-authored two papers with Mark Griffiths during my PhD at Nottingham Trent University (so far). Mark contributed significantly to both papers”.
Li Li (China)
“I confirm to you that Dr. Griffiths’ co-authorships on our papers were as a direct result of intellectually and physically writing and contributing to each of the papers he has co-published with me. In our papers, Dr. Griffiths and me analysed and interpreted the data. In addition, he also edited and contributed to the revised papers. I believe that he is an energetic and productive scholar”.
Arnaldo Rodríguez León (Cuba)
“I’m a Senior Cuban Cardiologist with 25 years’ experience in clinical cardiology…I decided to write to Professor Griffiths because he is and outstanding authority in this field [of social media addiction] and I had an original idea about it. We began to write the paper and sent each other more than 20 emails…I assure youProfessor Mark Griffiths wrote more than 50% of the paper. At the same time he continuously checked references, asked me questions about my draft, and when the article was almost ready he still was able to check some ideas. I’m deeply impressed because he works as a machine!!!”
Bruno Schivinski (Australia)
“I am writing you regarding the query initiated by Professor Bishop…I have co-authored and published with Professor Mark Griffiths three papers since 2018. I confirm his co-authorships on our papers. Professor Griffiths contributed to each of the papers both intellectually and by writing them. Furthermore, I would like to mention that Professor Griffiths is a role model in our profession”.
Aslam Mia (Malaysia)
“I have published one [article] recently with [Prof. Griffiths]. I would like to confirm that I am the one who approached [him] to be a co-author…due to his vast knowledge and expertise in the related field. Prof. Griffiths significantly contributed (e.g., strengthened the arguments, rewrote and revised the draft and raised several questions to be addressed…He did at least two rounds of revision before sending the paper to the journal. I have worked with around 25 researchers from at least 10 countries. And honestly speaking, I have not found anyone like Prof. Griffiths who is so active when it comes to joint research. I was mesmerized by his time management in delivering the joint work. It is sad to learn that someone is accusing him because he has published a lot”.
Shahla Ostovar (Iran)
“I have known Prof. Griffiths since 2014 and we have some publications together and two of them were published in 2020. Our publications in 2020 is a chain of hard working starting from 2016 with the basic idea from all authors including Prof. Griffiths. For writing each manuscript we had lots of communications with him. He really is more than a supervisor and co-author. He point-by-point guided us in both data analysis and writing to reach an acceptable manuscript. Then we tried some different journals to find a suitable house for our manuscripts. Both of our 2020 publications were reviewed over a long period of time and took more than 6 months to get acceptance. He is one of the key theoreticians in internet addiction and other addictions. It is obvious lots of researchers want to work with…[He is] generous in support [of] polishing ideas, analysis of data, and in writing the papers. Unfortunately, there are some jealous people who do not like Prof. Griffiths’ achievements…I can assure you that he contributed greatly to all my papers with him including the 2 published this year”.
Remya Lathabhavan (India)
“Dr Mark Griffiths contributed in discussion of the initial idea, writing, review and clarification on each other’s contribution, selection of journal, submission formalities and responses to reviewers for our work. He is a hardworking and sincere researcher who is reachable over mail any point of time for providing research advice and research communication for an early researcher like me”.
Zsolt Horvath (Hungary)
“I have two publications where [Dr. Griffiths] is listed as a co-author…I can confirm that in both cases Mark significantly contributed to writing and revising the manuscript”.
Alvaro Sicilia (Spain)
“After becoming aware of the controversy surrounding Professor Bishop’s blog about Professor Mark Griffiths, I am writing this email…I met Professor Griffiths in October 2018 while on sabbatical at Nottingham Trent University, which ended in October 2019. I recognise that Professor Griffiths’ production is prolific and I understand that this may attract the attention of other academics. However, once I shared a year of work with Professor Griffiths, I was able to see the high level of dedication to his work and the wide network of collaborations he has with researchers from all over the world…What I would like to put on record is that I can confirm that [he] has contributed to each of the articles that we have published together since 2019. His contribution has been varied and always enriching. In some cases, he has served as a critical expert incorporating substantial ideas into the study and reviewing the first drafts. On other occasions, he has contributed to the idea and design of the study itself, in addition to the process of writing the text. In any case, in many of the works published with Professor Griffiths, the tasks carried out by each of the co-authors have been made explicit….I do not want to end without expressing my appreciation for the contributions that Professor Griffiths has made in each of the works published or in preparation. Both for me and for my research team at the University of Almeria, it has been a pleasure to work together with Mark Griffiths and we hope that our collaboration can be maintained over time”.
David Fernandez (UK)
“I have, in total, two co-authored publications with [Dr. Griffiths]…I can attest that Mark contributed significantly to both of these publications, such that he unequivocally deserves co-authorship on them”.
Chung-Ying Lin (Hong Kong)
“I am writing this letter to confirm that [Dr. Griffiths] has contributed significantly to all my publications co-authored with him. I have also kept the records that can indicate Mark’s contribution”.
Zeyang Yang (Hong Kong)
“I confirm that Prof Mark Griffiths contributed to all our co-authored papers carefully with detailed corrections, feedback, and concerns. Mark contributed to all parts of our papers from Abstract to Conclusion with detailed comments on the sources of background information, theoretical and empirical literature discussing, data analysis selection, methods and results presentation, results discussion, research implications and even spelling errors”.
Zsolt Demetrovics (Hungary)
“I can confirm of course that [Dr. Griffiths’] co-authorship in our co-authored papers was in each case a result of [his] intellectual contribution and physical writing. Jack Grove has already approached me as well and wants to know more about the JBA review process”.
Halley Pontes (Australia)
“I am writing to you to give you some perspective about Professor Mark Griffiths in relation to the email you sent him regarding the blog entry by Professor Dorothy Bishop. Professor Mark Griffiths is one of the main founders (considered to be the founder in Europe) of a very controversial and highly relevant (in terms of public health) field of research. Professor Griffiths has been publishing his work on behavioural and technological addictions since the early 1990s, and as such, is recognised widely by his peers as one of the founders of the technological addictions field. Professor Griffiths has an extremely impressive network of collaborators from numerous countries and this is the main reason he is a prolific researcher (in addition to his hard work). I have worked with Professor Griffiths for nearly 10 years now, and we have co-authored a total of 74 research outputs together…Not only have I worked collaboratively with Professor Griffiths remotely (online), but also in a close context during the time I have lived in the UK where I would meet Professor Griffiths weekly at Nottingham Trent University. Of all the 74 published outputs I have with Professor Griffiths, all of them received substantial intellectual contribution and input from him. Professor Griffiths is not someone who gets his name on papers without having made a robust intellectual contribution. I can also attest to Professor Griffith’s high ethical standards and academic integrity as a result of working with him for so many years”.
Frank Buono (USA)
“I have been working with Dr. Griffiths for 5 years now, and during this time every manuscript that we have published together, he has provided direct insight in accordance to the publishing rights associated with American Psychological Association, and the respective journal’s by-laws…In [our] latest manuscript, ‘Gaming and Gaming Disorder: Mediation Model Gender, Salience, Age of Gaming Onset and Time Spent Gaming’, Dr. Griffiths as senior author provided 5 edits of the manuscript, after the manuscript was rejected from the first journal. He also, provided feedback in constructing letter of response to the editors”.
Alex Sumich (UK)
“I have known [Prof. Griffiths] for 10 years now, and have published several manuscripts with him…In all of these, he has contributed substantially in terms of study plan and writing…In [the cases I have co-published with him, Prof. Griffiths] attended (if not led) several meetings leading up to the first draft of the manuscripts, and based on his expertise and experience actively contributed to the planning of the studies through several discussions. In all cases, the initial drafts of the manuscripts were then written by the doctoral students. These were then circulated around co-authors for further input. In all cases, he made substantial and valuable suggestions for improving the manuscripts, typically contributing to 2-3 drafts prior to final submission. Following submission, each of these manuscripts received peer feedback and the research team discussed our response to issues raised. Thus, in my experience Prof Griffiths has very much earnt his position as co-author on all of these publications. [Prof Griffiths] has previously described himself as a ‘writing addict’. Writing is certainly his passion and he is incredible efficient at it. He has developed an excellent international collaborative network…Based on my own experience of working with Mark, I would feel confident that he would have contributed significantly to every publication that carries his name. He is a highly conscientious academic…Much of his work is in addiction research, and as such would naturally be published in specialist journals for addiction. Mark is also a very talented teacher, and mentor”.
David Columb (Ireland)
“I have worked with [Dr. Griffiths] on five published and one soon to be published article since I commenced research in the field of behavioural addiction about three years ago. Dr. Griffiths informed me about your upcoming article in relation to prolific publishing and a query on the credibility of Mark’s co-authored pieces. In every piece of research, I have worked with [Dr. Griffiths] on, he has contributed substantially to each one. I am only new to the research field and without his input on each paper we’ve done together, I imagine some of them would not be at publishing standard. It can actually be quite a chastening experience talking to Dr. Griffiths about our research topics and ideas as he can end up fixing the majority of it! I personally have never questioned Dr. Griffiths’ output as I have received emails on weekends and odd hours from him with multiple corrections and suggestions to papers, which shows someone dedicated to research and helping others with their research and would go some way to explaining his prolific publishing. He is also very willing to provide guidance on research whenever I would need some”.
Maria Ciccarelli (Italy)
“I am writing you to confirm that Dr. Griffiths’ co-authorship on my papers is the result of his contribution to papers I have co-published with him”.
Sabbir Ahmed (Bangladesh)
“Professor Griffiths is one of the best researchers and supervisors I have ever seen in my life. I have three co-authored papers with him. In every paper, he has significantly contributed from research design to manuscript writing. He is very hardworking and I am really happy to work with him. His scholastic guidance helps me to conduct some interesting research and in the future, I want to work more with him”.
Kagan Kircaburan (UK)
“Professor Griffiths’ co-authorships on all my papers were as a direct result of his intellectual and physical contributions. His contributions (in literature reviews, methods, analyses, and discussion sections) made each and every paper that I’ve published with him much better and publishable in good journals”.
Melina Throuvala (UK)
“I have been working with Professor Griffiths as a PhD student since September 2016 and am now a Lecturer at Nottingham Trent University in the Psychology Department. I would like to confirm that Professor Griffiths has contributed significantly to all of our co-authored papers. Working closely with him, I have witnessed first-hand his contribution to papers he co-authors. I do understand that the sheer number of publications can raise questions. However, never in my life have I met such a prolific author as Mark. His collaborations are a testament to his work ethic and expertise in this field, which he is diligently serving the last 30 years”.
Zhaojun Teng (China)
“As a lead author, this year I co-authored and published two articles [with Prof. Griffiths]. I confirm that he contributed to these works, and should be list as a co-author, according to CRediT (Contributor Roles Taxonomy). Each work, Prof. Griffiths paid much time and attention to work on the manuscript. From the draft writing, rejected by the journal, revising, and proof to publication, we needed at least 10 rounds of revision. I keep the email records. If needed, I can provide every version of these two articles”.
Gabriel Bonilla Zorita (UK)
“Personally, I can confirm that Mark as my supervisor has contributed a great deal with our publication. He is an incredibly dedicated academic and those who are near to him know that he put in hours of work like no other academic. I have no doubt of his integrity and legitimate contribution to all his co-authored publications and work”.
Paolo Soraci (Italy)
“I confirm that Professor Griffiths has contributed to my research (for example, reviewing the research, proposing ideas and changes, checking the bibliography, arranging the research layout and many other things). He has my most sincere regards”.
Saiful Islam (Bangladesh)
“I have co-authored with Dr. Griffiths. He is very supportive and contributes a direct result of intellectually and physically writing and editing to each of the papers. I really appreciated his extensive edits and guidance. Without physically writing and editing, he wouldn’t have been be a co-author with me”.
Ivan Ukhov and Johan Bjurgert (Sweden)
“We have had the pleasure to work with Professor Griffiths since around March 2019. In October 2019, we submitted a manuscript to the ‘Journal of Gambling Studies’, and in June 2020, it was accepted for publication. The contribution of Professor Griffiths to the work in question was substantial. We had numerous e-mail conversations, discussing the essence of the study and the delivery of the results by together iterating over the manuscript until convergence”.
Deena Dsouza (India)
“I really appreciate [Dr. Griffiths’] contribution as a co-author in the recent publication on the topic pertaining to online gaming…I am stating without any hesitation that Dr. Griffiths contributed intellectually and physically in writing the manuscript, until the last stage of proofreading. The manuscript has been the combined effort of all the authors. As an expert in this field, his contribution significantly impacted the manuscript. It was my pleasure working with him. His intellectual contribution, hard work, and passion towards research is appreciated undoubtedly”.
Alan Emond (UK)
“I am one of Prof. Griffiths’ collaborators. He has been advising me on the ALSPAC Gambling Study (based on Children of the Nineties cohort) for over 10 years, was a co-applicant on the grant which funded the analysis and contributed to the study design and analytic strategy. He edited and approved the report and papers arising from the study. One of the papers has been accepted by IJMHA, but was subject to a full peer review, and I received two critical reviews from gambling experts which I responded to in the revised manuscript. As far as I am concerned, Mark has been an excellent collaborator and has contributed intellectually to the research and fulfilled his responsibilities as a co-author”.
Nazire Hamutoğlu (Turkey)
“I would like to thank Dr. Griffiths for his contribution towards our article. I would kindly like to inform you that Dr. Griffiths materially contributed to the publication we co-authored. He is one of the best co-authors [and] made a marvellous contribution”.
Francesca Gioia (Italy)
“During my PhD course, supervised by Prof Valentina Boursier, I spent three months at the Nottingham Trent University. Prof. Mark Griffiths was my tutor during my PhD visit, kindly and willingly welcoming me at his lab, from September to November 2019. I can definitely assure you that Prof. Griffiths concretely contributed to critically revising the co-authored papers concerning my PhD research project”.
Valentina Boursier (Italy)
“Concerning my papers that Prof. Griffiths co-authored, I can absolutely confirm that he concretely contributed revising them critically. These works are part of our collaboration on my PhD student’s (Francesca Gioia) research project, that Dr. Gioia conducted with me in Italy and Prof. Griffiths supervised during her visiting at the Nottingham Trent University”.
Filipa Calado (UK)
“I have been working with Professor Griffiths since 2015, firstly as a PhD student, and now as a lecturer in Nottingham Trent University. I would like to confirm that Mark has strongly contributed to the papers that I am the first author. He actively contributed to the design of the studies, choice of the variables, theoretical background, and writing of the papers, among other things. Working with him has enabled me to deepen my knowledge on the field of behavioural addictions, and to start a career on this topic”.
Michael Auer (Austria)
“I have been working with Dr. Griffiths since 2010 and we published our first paper together in 2011. Since then we have published at least 30 papers together…I believe that our papers are quite complex as they are all empirical based on real-world data from various online gambling companies. My speciality is gambling research as I am also commercially involved in the industry. I can assure you that Mark is highly involved in all the publications and we at least run through five iterations until we are ready to submit a paper. So far we have managed to publish every paper that we worked on. I can imagine that it is quite unbelievable how much he publishes, but I’d say it is somehow his superpower. Everybody has one or more strengths and writing papers is for sure his!”
Francesco López-Fernández (Spain)
“I confirm the co-authorship of Mark in our paper due to his relevant contribution. He deeply reviewed the study several times providing important changes and commentaries during my research stay at Nottingham Trent University”.
Bernadette Kun (Hungary)
“I confirm that Professor Mark Griffiths intellectually and physically wrote and contributed to the papers he has co-published with me. I confirm that his work was very important and useful in our common papers”.
Sanju George (India)
“I have written/published with Professor Griffiths, both during my time in the UK and since my return to India. I can confidently state that in all the papers we have written/published together, Prof Griffiths has actively and fully contributed materially and intellectually”.
Andrzej Cudo (Poland)
“I would like to confirm that Professor Griffiths was co-author of my published paper, and his direct intellectual contribution and physical writing had primarily concerned the theoretical background and discussion related to the obtained results presented in my paper”.
