Ask a gambling regulator, a treatment charity, or an operator's own responsible-gambling team how they measure risk, and most of them are drawing on the same nine questions. The Problem Gambling Severity Index โ PGSI โ is the screening tool built into national prevalence surveys, embedded in many operators' self-assessment pages, and cited across the international research literature precisely because it is short, validated, and produces a single interpretable number. This guide walks through the instrument itself, shows exactly how the scoring works with a worked example, and explains what each risk band actually means โ so you can run it on yourself in about three minutes rather than encountering it for the first time buried inside an operator's account settings.
What the PGSI actually measures
The PGSI was developed as part of the Canadian Problem Gambling Index and has since been adopted, in the same or lightly adapted form, by national gambling-prevalence studies across multiple countries. It does not ask what games you play or how much money you wager โ it asks about the consequences and behaviour patterns associated with gambling over the past twelve months. That focus on consequence rather than volume is deliberate: a high-stakes player with full control and a small-stakes player chasing losses every week can land on opposite ends of the scale, because the instrument measures the relationship, not the size.
The nine questions
Each item is answered on a four-point scale: Never (0), Sometimes (1), Most of the time (2), Almost always (3). Thinking about the last twelve months:
- Have you bet more than you could really afford to lose?
- Have you needed to gamble with larger amounts of money to get the same feeling of excitement?
- When you gambled, did you go back another day to try to win back the money you lost?
- Have you borrowed money or sold anything to get money to gamble?
- Have you felt that you might have a problem with gambling?
- Has gambling caused you any health problems, including stress or anxiety?
- Have people criticised your betting or told you that you had a gambling problem, whether or not you thought it was true?
- Has your gambling caused any financial problems for you or your household?
- Have you felt guilty about the way you gamble, or about what happens when you gamble?
Scoring it: a worked example
Sum the nine answers. The maximum possible score is 27 (all nine at "almost always"); the minimum is 0. Take a sample set of answers: 1, 0, 2, 0, 1, 1, 0, 2, 1. Summed: 1+0+2+0+1+1+0+2+1 = 8.
The four risk bands
- 0 โ Non-problem gambling. No reported negative consequences from the last twelve months of play.
- 1โ2 โ Low risk. A small number of consequences reported at a low frequency. Worth noticing, not yet a pattern.
- 3โ7 โ Moderate risk. A level of negative consequences that research consistently associates with gambling starting to cause real harm โ this is the band prevalence surveys watch most closely, because it is the stage where intervention has the best odds of working before harm compounds.
- 8โ27 โ Problem gambling. The band associated with the most serious level of negative consequences measured by the instrument. A score of 8, from the worked example above, sits right at the threshold of this band.
A single number this size does not diagnose anything on its own โ the PGSI is a screening tool, not a clinical assessment โ but the band it lands in is a genuinely useful, evidence-based signal about whether the relationship with gambling described above needs a closer look, ideally from someone qualified rather than from a scorecard.
Why this instrument, specifically, is worth trusting
Self-assessment quizzes are everywhere online and most are unvalidated marketing dressed as concern. The PGSI's credibility comes from a different source: it has been tested for reliability and validity against real-world outcomes across large population samples, translated and used in national surveys, and its four-band structure is what actually informs the responsible-gambling tools built into licensed platforms โ deposit-limit prompts, cooling-off suggestions, and the self-exclusion options detailed in our guide to player-protection tools across borders. When an operator's account page shows a short quiz before letting you raise a deposit limit, there is a reasonable chance the questions underneath are drawn from this exact instrument.
What to actually do with your score
- 0โ2: No action needed beyond the general habit of re-checking periodically โ attitudes toward gambling drift gradually, and an annual three-minute check catches drift that a single bad month would not.
- 3โ7: This is the band where the lowest-friction tools do the most good. Setting a deposit limit before it feels necessary, using a short cooling-off period, or simply re-reading the questions after a losing week are all reasonable, proportionate responses at this level.
- 8+: This score warrants a conversation with a professional, not just a settings change. Every jurisdiction with a functioning regulator maintains a free, confidential helpline; our responsible gambling page lists multilingual support options that work in most countries, and using one is anonymous everywhere it exists.
How the PGSI compares to older screening tools
Before instruments like the PGSI became standard, population surveys mostly relied on older, longer clinical checklists adapted from other addictions research, which asked more invasive questions and produced results that were harder to compare across countries with different gambling markets. The PGSI was built specifically to be short enough for a general-population phone or online survey, worded in behavioural terms that translate reasonably well across languages, and validated against clinical assessment so that a given score band carries a consistent meaning wherever it is used. That consistency is exactly what makes it useful for a cross-border reader: a score of 8 means roughly the same thing whether the twelve months in question were spent playing at operators licensed in Malta, at a Curaรงao-licensed site, or at a fully domestic regulated market. Population-level studies that run the instrument regularly tend to find that the moderate-risk and problem-gambling bands together cover a single-digit percentage of past-year gamblers โ a minority, but a large enough one in absolute terms that most people either know someone in it or will, at some point, land there themselves for a season.
A note for the international, cross-border player
One awkward reality for the reader of this site specifically: the strongest downstream tools โ a national self-exclusion register that closes every licensed operator in one action โ exist only inside fully regulated domestic markets. A player using internationally licensed operators from a country without that infrastructure, whether checking in from Ireland, Hungary, or Romania, is more dependent on the operator-level tools and personal discipline described above, because there is no single register behind them to catch a moment of poor judgement. That is precisely why running this screen on yourself periodically, rather than waiting for a platform to prompt it, matters more for a cross-border player than for one inside a fully wired domestic market.
FAQ
Is the PGSI a medical diagnosis?
No. It is a validated screening instrument, and screening tools flag risk for further assessment โ they do not diagnose. A score of 8 or above is a strong signal to talk to a professional, who uses different, clinical criteria to actually assess gambling disorder.
Do I need to answer honestly for the score to mean anything?
Yes, and this is worth stating plainly: the instrument only works as a mirror if you look into it honestly. Nobody sees your answers unless you choose to share them; there is no benefit to under-reporting and no penalty for an honest one.
Can my score change over time?
Yes โ the instrument asks about the last twelve months specifically, so re-running it periodically tracks a rolling window rather than a permanent label. A score in the moderate-risk band during a stressful period can move back down once circumstances and habits change.
Do real regulators actually use this exact tool?
Versions of the PGSI, sometimes adapted slightly for local language and context, underpin national gambling-prevalence surveys and many operators' own self-assessment features across multiple countries โ one of the few instruments in this space with that level of independent validation behind it, rather than being written in-house by a single operator's marketing team.
