Gambling Addiction and Mental Health: What the Research Shows

For many people, gambling problems and mental health difficulties arrive together. One doesn't simply cause the other — the relationship is more complex, more circular, and more important to understand if recovery is going to be lasting. This piece draws on published research to explain what we know about gambling disorder and mental health, and what that means for treatment and support.

The Evidence: How Common Is Comorbidity?

"Comorbidity" refers to the presence of two or more conditions at the same time. In gambling disorder, it's the rule rather than the exception.

Research published in the British Journal of Psychiatry and data from the NHS and BeGambleAware consistently show:

These figures are striking. For comparison, the general population prevalence of depression is around 15–20%, and anxiety disorders around 15%. Problem gamblers experience these conditions at roughly two to three times the population rate.

Which Comes First — Gambling or Mental Illness?

This is one of the most studied questions in the field, and the answer is: it depends, and often both. Three main pathways have been identified:

Mental illness precedes gambling. In this pattern, someone develops depression or anxiety first, and gambling emerges as a way of coping — the dopamine hit, the distraction, the temporary escape from negative emotion. This is particularly common in what clinicians call "escape gamblers."

Gambling precedes mental illness. Financial losses, damaged relationships, shame, and the neurological effects of problem gambling all cause or worsen depression and anxiety. The gambling creates the mental health problem.

Shared underlying vulnerability. Some people have a neurological or genetic profile that makes them vulnerable to both. Research on dopaminergic functioning suggests that problem gamblers often have altered reward systems — changes that also underlie mood disorders and impulse control difficulties.

In practice, these pathways are rarely clean. Most people who present to treatment show elements of all three: pre-existing vulnerability, gambling as coping, and mental health worsened by gambling consequences.

The Suicide Risk Picture

This requires direct, clear communication. Problem gambling carries a significantly elevated suicide risk. Studies consistently find:

• Problem gamblers are between five and ten times more likely to have attempted suicide than the general population
• Financial catastrophe, shame, and the belief that gambling-related debts cannot be overcome are key risk factors
• Many people who die by suicide have gambling problems that were not identified by any service prior to their death

This is why GamCare, the NHS, and Gamblers Anonymous UK all screen for suicidal ideation as a routine part of support, and why the Samaritans (116 123) list gambling alongside other crisis risk factors. If you or someone you know is in immediate distress, please call 999 or contact Samaritans on 116 123.

How Mental Health Affects Recovery

Untreated mental health conditions significantly reduce the effectiveness of gambling treatment — and vice versa. Someone using gambling to manage severe anxiety is unlikely to stay in recovery without the anxiety being addressed at the same time.

This is why integrated treatment — addressing gambling and mental health together — produces better outcomes than treating either in isolation. The NHS problem gambling clinics, including the National Problem Gambling Clinic in London, offer this kind of multi-disciplinary approach. GamCare also delivers cognitive behavioural therapy (CBT) that explicitly addresses the interaction between mood and gambling behaviour.

What Effective Treatment Looks Like

A GP is often the best starting point — they can assess comorbid mental health conditions and refer to appropriate services. Be explicit about the gambling when you speak to your GP; it's still underdiagnosed in primary care settings.

Where to Get Help

The Bottom Line

Gambling disorder and mental health conditions reinforce each other. That's the bad news. The good news is that treatment works, and integrated approaches — addressing gambling and mental health together — work better than either alone. The research is clear: recovery is possible, and getting the right support is the most important thing you can do.

Reaching out to your GP, GamCare, or the National Problem Gambling Clinic is not a sign of weakness. It's the most evidence-based thing you can do.
