Problematic technology use during adolescence: why don’t teenagers seek treatment?
No full textIn recent issues of Education and Health, I have briefly reviewed the empirical evidence relating to problematic use of technology by adolescents including online video gaming (Griffiths, 2014), social networking (Griffiths, 2013a; Kuss & Griffiths, 2011), and mobile phone use (Griffiths, 2013b). Most of the research studies that have examined ‘technological addictions’ during adolescence have indicated that a small but significant minority experience severe problems resulting in detriments to education, physical fitness, psychological wellbeing, and family and personal relationships (Griffiths, 2010; Kuss, Griffiths, Karila & Billieux, 2014). Given these findings, why is it that so few teenagers seek treatment? This article briefly outlines a number of reasons why this might be the case by examining other literature on adolescent drug use and adolescent gambling (e.g., Chevalier & Griffiths, 2005; 2005; Griffiths, 2001). Three different types of explanation are discussed: (i) treatment-specific explanations, (ii) research-related explanations, and (iii) developmental and peer group explanations

Online 'penny auction' sites: regulation needed
No full textOnline 'penny auction' sites allow bidders to win expensive items at a price that appears unbelievably cheap, however users are charged by the site for each bid that they place. Dr, Mark Griffiths, a Professor of Gambling Studies at Nottingham Trent University, examines how 'penny auction' sites operate, and whether they should be regulated by the Gambling Commission

Positioning Learning Design: Learner Experience and the challenges of transforming teaching practice
No full textJohnson, M., Griffiths, D., & Hanslot, Z. (2010). Positioning Learning Design: Learner Experience and the challenges of transforming teaching practice. In D. Griffiths, & R. Koper (Eds.), Rethinking Learning and Employment at a Time of Economic Uncertainty. Proceedings of the 6th TENCompetence Open workshop (pp. 11-21). November, 19-20, 2009. Manchester, UK. Bolton, UK: Institute for Educational Cybernetics, The University of Bolton. For the complete book please see http://hdl.handle.net/1820/3191Whilst effective design of reproducible learning experiences is perceived to be strategically important for educational institutions and many tools to assist in the processes of design and coordination have been developed, evidence suggests that these tools have had little success in gaining traction within the broad user base of teachers and learners.
Using a case-study of the international expansion of a UK university, we show how an examination of the design of reproducible learner experiences which facilitates the separation of design from delivery has been necessitated. We describe an international computer-coordinated learning activity which has been designed to simulate the situation of international delivery and highlight communicational practice. The exercise also models the practices of online activity design and its efficacy in cross-cultural situations.
Through an analysis both of the problem of the University and the activity to develop staff, we create a model of the conditions for the more widespread adoption of LD technology in the sector. To produce this model, we draw on the findings of the JISC SPLICE project, which aimed to change practice with social software, and on the Positioning Theory of Harré. We argue that with the redescription of the case-study using these distinctions, the priority to maximise the effectiveness of communications in the institution, the provision of good teaching and the coordination of a multi-national educational operation can be linked. Given these priorities, the model shows LD technology presenting a natural solution both for teachers and educational managers.The work on this publication has been sponsored by the TENCompetence Integrated Project that is funded by the European Commission's 6th Framework Programme, priority IST/Technology Enhanced Learning.

Theoretical Loss and Gambling Intensity (Revisited): A Response to Braverman et al. (2013)
No full textIn this paper, we provide a brief response to Braverman and colleagues’ (2013) critique of our ‘Theoretical Loss’ metric as a measure of monetary gambling intensity (Auer & Griffiths, 2013; Auer, Schneeberger & Griffiths, 2012). We argue that ‘gambling intensity’ and ‘gambling involvement’ are essentially the same construct as descriptors of monetary gambling activity. Additionally, we acknowledge that playing duration (i.e., the amount of time – as opposed to money – actually spent gambling) is clearly another important indicator of gambling involvement – something that we have consistently noted in our previous studies including our empirical studies on gambling using behavioural tracking data. Braverman and colleagues claim that the concept of Theoretical Loss is nullified when statistical analysis focuses solely on one game type as the house edge is constant across all games. In fact, they state, the correlation between total amount wagered and Theoretical Loss is perfect. Unfortunately, this is incorrect. To disprove the claim made, we demonstrate that in sports betting (i.e., a single game type), the amount wagered does not reflect monetary gambling involvement using actual payout percentage data (based on 52,500 independent bets provided to us by an online European bookmaker). After reviewing the arguments presented by Braverman and colleagues, we are still of the view that when it comes to purely monetary measures of ‘gambling intensity’, the Theoretical Loss metric is a more robust and accurate measure than other financial proxy measures such as ‘amount wagered’ (i.e., bet size) as a measure of what players are prepared to financially risk while gambling

Gaming addiction in adolescence (revisited)
No full textGaming addiction has become a topic of increasing research interest. Over the last 25 years, I have written many articles on adolescent video gaming for Education and Health as it is one of the research fields that is constantly evolving. In fact, over the last decade, there has been a significant increase in the number of scientific studies examining various aspects of online addiction particularly among adolescents and young adults (Kuss & Griffiths, 2012; Kuss, Griffiths, Karila & Billieux, 2014). Although the amount and the quality of research in the field has progressed much over this period, it is still in its infancy compared to other more established behavioural addictions (such as pathological gambling). This article briefly examines (i) how adolescent gaming addiction research has changed over the last three decades, (ii) how online gaming addiction has gained genuine psychiatric status, (iii) excessive gaming as an addiction, and (iv) where the gaming addiction field is going
