“…The objective of this secondary analysis of a trial of brief motivational interventions with high expenditure gamblers was to explore the heterogeneity in the target population of big losers and how different types of gamblers respond differently to the interventions. In the earlier analyses of the data (Jonsson et al 2019(Jonsson et al , 2020, these high consumers were treated as a homogeneous group. In this paper, a LCA identified six classes based on involvement in different gambling forms: 'High Casino', 'High Sport', 'High Lottery', 'High VLT', 'Lottery/Mix' and 'Bingo/Casino'.…”

“…1 Since 2015, NT has been contacting high consumers by telephone and letter, aiming at encouraging the customers to reflect upon their gambling habits and guide them into taking action if desired and warranted. In a randomized controlled study with 1003 matched participants in each arm (telephone contact, letter contact and no contact control condition), the telephone intervention showed a clear effect short term (12 weeks) and the effect was stable over 12 months (Jonsson et al 2019(Jonsson et al , 2020, see Fig. 1.…”

“…This finding provides some support that RG measures could have different effects for different kinds of players. The current study addresses this research gap by examining how an RG intervention that targets high expenditure customers (Jonsson et al 2019(Jonsson et al , 2020, differentially impacts gamblers that are participating in different forms of gambling. In the earlier analyses of the data, the high consumers were treated as a homogeneous group despite different patterns of involvement with different forms of gambling.…”

Telephone and letter-based motivational interventions with high expenditure gamblers have significant short and long term positive effects on gambling and use of responsible gambling tools. This report examines how different subtypes of gamblers, based upon patterns of play, are differentially affected. A randomized controlled trial design with three conditions (n = 1003 in each): feedback intervention by letter, telephone or a no-contact control condition. Subtypes of gamblers were derived by latent class analyses (LCA) based upon gambling behavior pre intervention. The participants were customers of Norsk Tipping gambling platforms. 1003 statistical triplets from the top 0.5% of customers based upon annual expenditure, matched on sex, age, and net losses. Primary outcome measure was gambling theoretical loss (TL), derived from the Norsk Tipping customer database. The LCA identified six subtypes: High Casino, High Sport, High Lottery, High Video lottery terminal (VLT), Lottery/Mix and Bingo/Casino. There were almost no differences in change in TL between the six subtypes of gamblers receiving the letter or telefone interventions respectively. However, the choice of contact by letter or telephone did have different effects for the different gambling subtypes. Sending a letter seems like a cost effective alternative to telephone contact for the High Lottery type, but telephone contact performs better for High Casino, High Sport and High VLT customers. Responsible gambling interventions can be improved by subtyping of gamblers.

“…Researchers have suggested that RG measures need to be more proactive Smith 2017a, 2017b). Jonsson et al (2019) investigated the use of behavioral feedback via telephone aimed at excessive gamblers. Gamblers that received feedback via telephone had a 29% decrease in theoretical losses compared to 3% for the control group.…”

Introduction: Besides supply reduction, preventive interventions to reduce harm from gambling include interventions for the reduction of demand and to limit negative consequences. Several interventions are available for gamblers, e.g. limit-setting. Reviews have been published examining the evidence for specific measures as well as evaluating the effect of different measures at an overall level. Only a few of these have used a systematic approach for their literature review. The aim of this systematic review and meta-analysis is twofold. First, to assess the certainty of evidence of different preventive measures in the field of educational programs and consumer protection measures, including both land-based and online gambling. The second is to present shortcomings in eligible studies to highlight what type of information is needed in future studies. Method: This systematic review included measures administered in both real-life settings and online. Twenty-eight studies fulfilled our inclusion criteria and had low or moderate risk of bias. Results: The results showed that only two measures (long term educational programs and personalized feedback) had an impact on gambling behavior. Follow-up period was short, and measures did not include gambling as a problem. The certainty in most outcomes, according to GRADE, was very low. Several shortcomings were found in the studies. Discussion: We concluded that the support for preventive measures is low and that a consensus statement regarding execution and methods to collect and analyze data for preventive gambling research is needed. Our review can serve as a starting point for future responsible gambling reviews since it evaluated certainty of evidence.

“…For instance, 13 of the 14 CBT studies included in a Cochrane review of psychological treatments for gambling disorder included a measure of financial losses (Cowlishaw et al, 2012). These reports can be self-reported using diary-type methods, such as the timeline follow-back (TLFB; Weinstock, Whelan, & Meyers, 2004), or using singleitem scales, or be based on real player data, e.g., when a responsible gambling intervention is evaluated in collaboration with the industry (Auer & Griffiths, 2016;Ivanova, Magnusson, & Carlbring, 2019;Jonsson, Hodgins, Munck, & Carlbring, 2019). Behavioral measures commonly focus on days gambled and net money lost, which are thought to capture the majority of negative consequences associated with excessive gambling (Walker et al, 2006, p. 505).…”

Clinical studies investigating treatments for problem gambling or gambling disorder frequently use gambling expenditure, such as gambling losses, as a treatment outcome. Gambling losses frequently vary substantially between participants; some report no losses, and some report substantial losses. In this article, we review how gambling losses are commonly analyzed in treatment studies, and show that frequently used methods, such as a log(y+1) transformation or assuming a normal distribution, often perform poorly for these types of data. We propose that a marginalized longitudinal two-part model is a more attractive option. The models are compared using real data from a trial including 136 persons with gambling disorder. Additionally, different performance metrics are further evaluated in a Monte Carlo simulation study. We conclude that gambling researchers should consider using the longitudinal two-part model as it offers a flexible and powerful way of modeling gambling outcomes. The log(y + 1) transformation can be highly misleading in typical gambling data, as a difference in the number of zeros leads to biased estimates of the treatment effects.
