The Problem
A board sitting in front of a player protection update usually sees one headline figure: the proportion of customers who meet the criteria for problem gambling, often reported as flat or falling, and treated as proof that responsible gambling controls are working. That number is real, and it matters, but it is narrower than most boards assume, because it counts people who meet a clinical or behavioural threshold, and it says nothing about the customer who is losing more than they can afford without ever crossing that threshold, or the partner managing shared finances around someone else’s betting, or the adult child covering a parent’s debts. The two ideas, problem gambling and gambling harm, get used as if they were interchangeable in board packs and marketing copy, and that slippage is not just semantic. A board that only asks how many customers are problem gamblers is asking a smaller and less useful question than how much harm its product is causing, and it can end up reporting a clean trend line on the wrong metric while real, measurable harm sits just outside the frame.
How It Actually Works
Problem gambling is a clinical or behavioural classification. It is usually measured through a validated screening tool, most often the Problem Gambling Severity Index or DSM-5 based criteria, and it produces a count of individuals whose gambling meets a defined threshold of loss of control, chasing losses, or negative consequences severe enough to score as a disorder. It is precise, it is comparable over time, and it is genuinely useful, but it is a diagnostic category, so by design it only captures people at the more severe end of a spectrum.
Gambling harm is a broader public health concept, and it covers financial, relationship, health, occupational and social harms that can arise at any level of gambling participation, including levels well below a diagnosable disorder, and including harm experienced by people who never place a bet themselves. Public Health England’s 2021 review of gambling-related harms found that 0.5% of adults in England met the criteria for a gambling problem, but that 7% of adults, fourteen times that number, were negatively affected by someone else’s gambling, and it grouped the harm itself into six categories: financial, relationship disruption or breakdown, mental and physical health, cultural, reduced performance at work or in education, and criminal activity. Most of that harm happens to people who would never appear in a problem gambling prevalence figure, because they are not the one placing the bet.
The UK Gambling Commission has moved its own language accordingly, describing its measurement work as a shift away from simply counting problem gamblers and toward tracking harms, whether temporary or lasting, that extend beyond the gambler to their friends, family and community. Its evidence work links gambling to outcomes including bankruptcy, anxiety, depression, intimate partner violence and suicidal ideation, treating a customer’s own diagnostic status as one input among several rather than the whole picture.
US regulators are converging on the same point through their own research, not by borrowing the UK’s framing. A 2021 study commissioned by the Massachusetts Gaming Commission, built on the state’s SEIGMA cohort research at UMass Amherst, found that only around 2% of Massachusetts adults met the criteria for problem gambling and a further 8% were classed as at-risk, yet people outside the single highest severity group accounted for close to three quarters of all the harm reported across the state, a pattern the researchers named the prevention paradox. Because non-problem gamblers vastly outnumber problem gamblers, their combined lower-level harm adds up to more than the harm concentrated in that smallest, most severe group, and a board reading only a problem gambling percentage misses that arithmetic.
The pattern holds outside the UK and the US too, a settled direction of travel rather than one regulator’s quirk. Victoria’s Department of Health, in Australia, defines gambling harm as any negative consequence, from momentary guilt through to bankruptcy, broken relationships and thoughts of suicide, keeping problem gambling as the narrower, PGSI-measured category inside that wider definition, and its own research puts adults personally affected by someone else’s gambling at over 5%, close to the PHE figure for England. In Canada, the Conceptual Framework of Harmful Gambling, developed by Abbott and colleagues for the Gambling Research Exchange Ontario and now in its third international edition, makes the same distinction its organising principle: gambling disorder sits at the most severe end of a spectrum of harm, not the definition of harm itself, and the framework tracks effects on families and communities across generations, not just the person who gambled.
This has real practical consequences for how operators must measure and act, not just talk. The UK’s financial risk checks set thresholds on deposit patterns rather than diagnosis, and the Gambling Commission moved to a staged rollout from July 2026: an initial threshold of £5,000 in net deposits within a rolling 24 hours for customers aged 25 and over, tightening in later stages to £1,000 in 24 hours or £3,000 over 90 days, with lower thresholds throughout for under-25s, £2,500 initially, falling to £750 in 24 hours or £2,000 over 90 days. Ontario’s AGCO builds its iGaming standards around the same logic, requiring risk profiles from behavioural and financial indicators, chasing losses, erratic betting, session length, refusal of limit tools. Both are harm framing operating as regulation, and a board that only tracks problem gambling prevalence will not see this layer of activity in either market.
A Practical Way In
A short set of questions a board can put to its own player protection reporting, not exhaustive, but enough to expose whether the wrong number is being watched:
– When we quote a “problem gambling” figure, what exactly sits behind it: a screening score, a self-exclusion count, an account closure count, and which population does it cover?
– Do any of our harm metrics capture people who are not our account holders, such as partners or family members, or does everything we report stop at the customer relationship?
– Are we tracking indicators that sit below a diagnostic threshold, such as loss velocity, session length and chasing patterns, or only counting customers who have already crossed into a clinical category?
– Does our escalation and intervention policy trigger on behavioural and financial harm indicators as well as on formal problem gambling flags, in line with how regulators from the UK to Ontario are now building these triggers?
– If our reported problem gambling prevalence stayed flat or fell next quarter, would we actually know whether harm across our customer base had also fallen, or only that fewer people met one particular threshold?
Where This Goes Deeper
Building a measurement framework that tracks harm properly, across account holders and affected others, across the full severity spectrum and not just the diagnosed end, and mapped to what regulators in multiple markets are now actually checking for, is exactly the kind of structured work one of TGB’s Tools or an Expert Session is built to get right. If your board reporting still leans mainly on a single problem gambling percentage, it is worth seeing whether a broader harm framework changes what you are actually measuring.
