Recognising gambling harm

What "harm" means

The language matters here, because two different things are often merged.

The Gambling Commission defines problem gambling as "gambling to a degree that compromises, disrupts or damages family, personal or recreational pursuits"¹. That describes the person gambling.

Gambling-related harms are broader: "the adverse impacts from gambling on the health and wellbeing of individuals, families, communities and society"¹. These include loss of employment, debt, crime, relationship breakdown, and deterioration in mental and physical health¹.

The distinction is practical rather than academic. Harms "can be experienced by those who gamble themselves, but can also affect their children, partners, wider families and social networks, employers, communities and society as a whole"¹. Someone can be harmed without gambling at all.

Because of that, measuring only the number of people who meet a problem gambling threshold understates the picture, as it misses harms experienced by affected others¹.

Signs in behaviour

Behaviour usually changes before money does, because early losses are absorbed quietly.

• Sessions running longer than intended, repeatedly.
• Gambling at times that do not fit the rest of the day, particularly at night.
• Secrecy: closing screens, vague answers about time, a second device or account.
• Withdrawing from activities or people that used to matter.
• Returning quickly after a withdrawal, so money never really leaves.

The clinical framing covers the same ground. The American Psychiatric Association lists "Repeated unsuccessful efforts to control, cut back on, or stop gambling" and "Lying to hide the extent of gambling involvement" among the criteria for gambling disorder⁴.

Signs in money

Financial signs arrive later but are the least ambiguous.

The NHS uses four direct questions as a starting point: whether you "bet more than you can afford to lose", whether you "need to gamble with larger amounts of money to get the same feeling", whether you have "tried to win back money you have lost (chasing losses)", and whether you have "borrowed money or sold anything to get money to gamble"³.

Other markers worth watching are unexplained transfers between accounts, use of credit or buy-now-pay-later facilities to cover ordinary spending, bills paid late while money moves elsewhere, and money intended for something specific being redirected.

Signs in mood

The mood signs are the ones most often dismissed, and the most predictive.

The APA criteria include "Restlessness or irritability when trying to cut down or stop gambling", "Gambling when trying to escape from problems, negative mood, or stress" and "Often gambling when feeling distressed"⁴.

The shift to watch for is one of function. Gambling that began as entertainment becomes a way of managing a feeling. At that point the amount staked stops being the useful measure.

Screening tools by name

Two validated instruments are used widely, and both are public.

The Problem Gambling Severity Index

The PGSI is the nine scored items within the Canadian Problem Gambling Index, developed by Jackie Ferris and Harold Wynne and published as "The Canadian Problem Gambling Index: Final Report" in 2001². Scores classify respondents into non-problem, low risk, moderate risk and problem gambling groups².

The NHS publishes the same nine-question self-assessment, scored "never (0 points), sometimes (1), most of the time (2), almost always (3)", and states that "If your total score is 8 or higher, you or those closest to you, are likely to be experiencing gambling-related harms"³.

The Commission uses screening tools such as the PGSI in its own measurement of problem gambling¹.

The DSM-5 criteria for gambling disorder

The American Psychiatric Association describes gambling disorder as "a pattern of repeated and ongoing betting and wagering that continues despite creating multiple problems in several areas of an individual's life"⁴.

Diagnosis requires at least four of ten criteria during the past year⁴. Those criteria include preoccupation with gambling, needing to gamble with increasing amounts, unsuccessful attempts to stop, restlessness when cutting down, gambling to escape distress, chasing losses, lying about gambling, losing important opportunities, and relying on others to resolve money problems caused by gambling⁴.

How harm develops

Harm tends to build through a sequence rather than arriving at once.

1. Tolerance. The same stake produces less of the original feeling, so stakes or session length rise. The APA lists the "Need to gamble with increasing amounts to achieve desired excitement"⁴.
2. Chasing. Losses are pursued rather than absorbed. GambleAware states that "Trying to win back your losses often leads to even bigger losses"⁵.
3. Concealment. Disclosure becomes selective, which removes the external checks that would normally slow things down⁴.
4. Displacement. Money, time and attention move away from other commitments¹.
5. Dependence on gambling to regulate mood. Gambling is used to manage stress or low mood rather than for enjoyment⁴.

The order varies, and someone can be at step four without ever having placed a large single bet. Frequency and function matter more than stake size.

Talking to someone you are worried about

There is no perfect script, but some approaches reliably work better than others.

Do:

• Pick a calm, private moment rather than the aftermath of a loss.
• Describe what you have observed, not what you have concluded. "You have been up until three most nights this week" lands differently from an accusation.
• Ask open questions and leave silence for the answer.
• Say what you are worried about, including the effect on you.
• Offer a specific next step, such as looking at a self-assessment together, rather than a general demand to stop.

Avoid:

• Paying off a debt on the expectation that it ends the behaviour. The APA lists "Relying on others to help with money problems caused by gambling" as one of the criteria for gambling disorder, which is a reason to be careful rather than an accusation⁴.
• Ultimatums you are not prepared to follow through.
• Framing it as a failure of willpower.
• Policing accounts secretly, which usually ends the conversation permanently.

Support exists specifically for people affected by someone else's gambling, including groups named by the NHS such as GamAnon and GamFam³.

What to do next

If several signs are present, the most useful actions are practical and immediate.

• Complete a self-assessment honestly, using the nine-question NHS version³.
• Put a hard stop in place while you decide what to do. The options are set out in self-exclusion and blocking tools.
• Set account-level limits, covered in deposit and loss limits.
• Work out what the activity actually costs, using working out the cost per hour.
• Talk to a free, confidential service. The NHS names the National Gambling Helpline, run by GamCare, as free and available 24 hours a day, seven days a week³.

Specialist NHS gambling clinics operate across England, with self-referral available through regional services³.
