Problem gambling is gambling that causes harm to you or the people around you and starts to disrupt daily life, such as money, work, health or relationships. The term covers a wide range, from early trouble to a diagnosed medical condition.
It sits in our Responsible gambling and psychology section, for anyone who is curious or worried.
What is problem gambling in plain words?
Problem gambling is gambling behavior that damages a person or their family and often disrupts daily life and work. The National Council on Problem Gambling (NCPG) calls it an emotional problem with financial and other consequences, not only a money problem. The amount lost or won does not decide it. Harm to health, relationships and work does.

That last point surprises many people. The NCPG says a person can have a gambling problem without gambling every day, because occasional gambling can still cause damage.
How is problem gambling different from gambling disorder and gambling addiction?
Problem gambling is the broad, everyday term. Gambling disorder is the medical diagnosis. Gambling addiction is a common name for the same pattern. The NCPG says the three names are used for the same thing, while the Partnership to End Addiction uses problem gambling for trouble that falls short of the full diagnosis.
| Term | How it is used | Where it comes from |
|---|---|---|
| Gambling harm | Any negative effect of gambling on health, money, relationships or work, with or without a diagnosis | WHO describes harm below clinical thresholds, such as money for essentials going on gambling |
| Problem gambling | Gambling that causes trouble in daily life. Some sources use it as a synonym for the disorder, others for milder trouble | NCPG (synonym); Partnership to End Addiction (milder than the disorder) |
| Gambling addiction | A common name for the same pattern as the disorder | NCPG |
| Gambling disorder | The clinical diagnosis. DSM-5 needs four or more listed signs within 12 months | APA and DSM-5; WHO (ICD-11 has its own three requirements) |
The World Health Organization (WHO) says gambling disorder is classed beside substance use disorders in both DSM-5 and ICD-11, the two main diagnostic manuals.
What does a gambling disorder diagnosis look for?
A diagnosis looks for a pattern of repeated and ongoing betting that carries on despite problems in several parts of life. The American Psychiatric Association (APA) says it requires at least four listed signs during the past year. Only a trained professional can make the diagnosis.
DSM-5 lists nine behaviors, as presented by the Nevada Council on Problem Gambling. We grouped them in our own words.
| Theme | Signs in plain words |
|---|---|
| Control and preoccupation | Constant thoughts about gambling; repeated failed attempts to cut back or stop; restlessness or irritability when trying to cut down |
| Escalation and chasing | Needing larger bets to get the same excitement; going back another day to win back what was lost |
| Coping and secrecy | Gambling when feeling helpless, guilty, anxious or low; lying to hide how much |
| Fallout | Putting a relationship, job or study opportunity at risk; relying on other people for money to fix gambling debts |
The count also sets the severity. On the DSM-5 scale, 4 to 5 signs is mild, 6 to 7 is moderate, and 8 to 9 is severe. The diagnosis also requires that the behavior is not better explained by a manic episode.
The pattern can be episodic, with quiet spells of several months between periods, or persistent over years.
ICD-11 asks for three things instead: impaired control, gambling taking priority over other interests, and carrying on despite negative consequences.
How do screening tools measure problem gambling?
Screening tools such as the Problem Gambling Severity Index (PGSI) turn nine questions into a score from 0 to 27. Higher scores mean more signs of harm. The PGSI is a screen that shows where someone sits on the scale, not a diagnosis.
The Gambling Commission explains that each of the nine items is rated on a four-point scale and that scores fall into four bands, shown below (Gambling Survey for Great Britain, 2024). The NHS uses a similar nine-question check, scored 0 for never up to 3 for almost always.
| PGSI score | Band | Plain meaning |
|---|---|---|
| 0 | Non-problem | Gambles but reports none of the nine signs |
| 1 to 2 | Low risk | A few signs. Worth noticing early |
| 3 to 7 | Moderate risk | Several signs. Gambling may be affecting daily life |
| 8 or more | Problem gambling band | Many signs. Seeking support is advised |
Here is the arithmetic. Nine items, each scored 0 to 3, give a top score of 9 times 3, which is 27. A person who answers sometimes (score 1) to six items and never (score 0) to three items scores 6. That falls in the moderate band, still a signal to act early.
The NHS adds that even a score of 1 to 7 can mean gambling is having a negative effect.
How common is problem gambling?
Estimates range from about 1% to more than 4% of adults, depending on the country, the question asked and the survey method. No single number applies everywhere, and none is a guide to any one person. The table puts the main figures side by side.
| Source | Place and year | Figure | What it measures |
|---|---|---|---|
| NCPG | United States | About 2.5 million adults (1%) | Meet the criteria for a severe gambling problem in a given year |
| NCPG | United States | 5 to 8 million adults (2% to 3%) | Mild or moderate problems, short of the full criteria |
| WHO (2024) | World | 1.2% of adults | Estimated to have a gambling disorder; global figures are limited |
| Gambling Commission | Great Britain, 2024 | 2.7% of survey participants | PGSI score of 8 or more |
The gaps come from different yardsticks: a diagnosis, a screening score, or a level of harm. The Gambling Commission notes its survey typically produces higher PGSI scores than older face-to-face surveys.
The wider circle matters too. The WHO says that for each person gambling at high-risk levels, an average of six others are affected, and that most of them do not gamble themselves. The Wyoming Department of Health puts it higher, at 8 to 10 people. Either way, far more people are touched than the headline figures suggest.
Who can be affected, and what raises the risk?
Anyone who gambles can be affected, at any age and from any background, though the APA says most people who gamble for fun do not develop a disorder. Researchers have found factors that raise the odds, but no single cause.

The sources point to several groups of factors:
- Life events and pressure. The WHO lists separation, retirement, injury and bereavement, along with poverty, discrimination and other disadvantage.
- Easy access and heavy promotion. The WHO says gambling opportunities often cluster in poorer areas, and that heavy promotion normalizes gambling for young people.
- Other health conditions. GamCare notes that gambling harm often occurs alongside emotional regulation difficulties, depression, ADHD, impulse control problems and trauma-related conditions.
- Family history and age. The NCPG says genetics, environment, medical history and age may play a part, and that starting young raises the chance of later problems.
The NCPG is clear that casinos and lotteries provide the opportunity to gamble but do not cause the problem by themselves. For how product design can keep people playing, see our guide to how gambling games hold your attention.
What does problem gambling look like day to day?
It often looks like a growing share of time, money and attention going to gambling, and a growing effort to keep it hidden. GamCare calls it a hidden addiction because the visible signs seen with alcohol or drugs are often missing, and online play can be discreet.
Common signs include:
- Thinking about gambling all the time, or betting more to get the same feeling
- Going back to win back losses
- Borrowing money, selling things, or hiding bets from family and friends
- Letting work, study or relationships slip
One sign alone does not mean a disorder, but several together, or one causing real damage, is a good reason to talk to someone. Our warning signs guide has a private self-check.
Which kinds of gambling carry the most risk?
The WHO says electronic gambling machines and casino games, in person and online, are most often linked with harm. Other sources say harm can come from any form of gambling, so no format is automatically safe.
The NCPG says any type can become a problem, and that fast-paced games may carry extra risk, although this is poorly understood.
Cost is part of the picture. Every gambling game has a house edge, so the longer someone plays, the more they lose on average. A limit set in advance helps. See how to set a gambling budget and time limit.
Can problem gambling be treated?
Yes, gambling problems can be treated. The WHO says the most effective treatments are long-term cognitive behavioral therapy and motivational interviewing, and the NCPG says recovery is built on changing habits with social support. The APA adds that symptoms can ease and return, so a setback is not proof that help has failed.
| Option | What it is | What the sources say |
|---|---|---|
| Cognitive behavioral therapy (CBT) | Talking therapy that works on thoughts and habits around gambling | WHO: among the most effective options when delivered over the long term |
| Motivational interviewing | A guided conversation that builds the person’s own reasons to change | WHO: among the most effective options |
| Mutual support groups | Peer groups such as Gamblers Anonymous and, for families, Gam-Anon | WHO: weaker evidence, though widely used |
| Medication | Some medicines help with co-occurring conditions such as depression or anxiety | APA: no US FDA-approved medication for gambling disorder itself |
| Blocking and self-exclusion tools | Tools that stop access to gambling sites, venues or payments | WHO: universal, mandatory systems work best; voluntary ones have poor uptake |
Few people reach treatment: the APA says only about one in ten people with gambling disorder seek it. The WHO names stigma and shame as major barriers, and GamCare says the same.
What can you do today if you are worried?
You do not need a diagnosis to ask for help. The WHO says harm can occur well below the level of a diagnosis, for example when money for essentials goes on gambling. Free, confidential helplines exist for the person gambling and for family and friends.
- Talk to someone you trust, or call a free helpline.
- Check where you stand. Take the NHS nine-question check or the private self-check in our warning signs guide.
- Add a barrier. The NHS lists blocking tools and asking your bank to block gambling payments. In Great Britain, GAMSTOP can block gambling sites and apps for 6 months, 1 year or 5 years.
- Ask a professional. In England you can refer yourself to an NHS gambling clinic or ask your GP. Elsewhere, ask a doctor or local health service.
