In terms of situational factors, there has also been a substantial increase in the proliferation of marketing and advertising for online sports betting which is also likely to contribute to the higher proportion of impulsive sports bets made online (Hing et al. 2017; Sproston et al. 2015). The information conveyed in such promotional material emphasises the ease of access and value for money of online sports betting (Hing et al. 2015; Sproston et al. 2015); and its propagation has led to online sports betting to be normalised and perceived as an everyday behaviour, สถิติหวยฮานอย วีไอพี especially among young adults (Deans et al. 2016; Gordon et al. 2015). Promotional sports betting material and inducements delivered via direct marketing such as email and SMS are believed to precipitate impulsive sports betting online (Hing et al. 2017). In terms of indirect marketing, Lamont et al. (2016) observed that participants would be more likely to make impulsive bets in response to live odds being presented on sporting broadcasts, and moreover, the effect was stronger in participants with higher severity of problem gambling.In addition, problem gambling has repeatedly been demonstrated to be strongly associated with activities with high event frequency, and with modern online sports betting features, gamblers now have the opportunity to place a larger number of bets on a single event (Auer and Griffiths 2013; Hing et al. 2017). The increased capacity to bet rapidly and continuously in modern online sports betting has been proposed as a potential risk factor for disordered gambling. The lack of environmental distractions in online betting in comparison to in-venue betting may lead to an increased level of immersion experienced in the activity, which in turn is likely to increase dissociation levels, culminating in less cognitive control when gambling (Hing et al. 2018a, b). Furthermore, in relation to the asocial and private nature of online sports betting, there is an increased risk of players not recognising the development or problematic patterns of online sports betting and persisting until a crisis point is reached, in comparison to in-venue gambling (Estevez et al. 2017; Gainsbury et al. 2013; Petry 2006).
The normalisation and embedding of online sports betting into an everyday activity through promotional marketing, and the structural changes of the activity that appear to facilitate risky patterns of gambling behaviour, emphasises the need to understand the mechanisms of online sports betting behaviour in detail (Hing et al. 2016a, b). More specifically, Hing and colleagues (Hing et al. 2018a, b) advocated that the specific behavioural patterns of recreational and problematic gamblers in online sports betting should be contrasted to identify behavioural patterns which could be considered particularly disordered, such as betting sessions with excessive durations continuing late into the night.It is evident that there is a need to begin development of interventions to assist with moderating and mediating the negative consequences that can arise from excessive and pathological engagement with this form of gambling (Estevez et al. 2017; Killick and Griffiths 2018). Although there are several research articles identifying a relationship between developments in the structural and situational characteristics of online sports betting, the research is largely dependent on self-report survey and qualitative data. A review of the aforementioned literature base indicates that there is insufficient theoretical understanding of the causal and maintenance factors in problem online sports betting (Hing et al. 2016a, b), and therefore, it is not currently possible to propose potential interventions to commence trialling for effectiveness (Parke et al. 2016). In fact, because of inconsistencies in the assessment of online sports betting behaviour, in terms of how the behaviour is classified across different studies in the international prevalence literature, it is not possible to outline even simplistic trends in online sports betting behavioural patterns (Lopez-Gonzalez et al. 2017; Hing et al. 2018a, b). Therefore, it is prudent to stimulate the generation of substantive theory related to the problem online sports betting and identify key variables and indeed theoretical relationships in order to inform attempts to address gambling-related harm in this realm. In particular, although multiple articles make strong arguments about the elevated risk for problem gambling in modern online sports betting, these arguments have yet to be substantiated through ecologically valid behavioural studies. The current study aims to identify processes and patterns of gambling behaviour related to multiple forms of harm in a cohort of online sports betting problem gamblers, by analysing objectively recorded behavioural data over a continuous 3-month period.
