What is the connection between problem gambling and other mental health issues like depression or anxiety?

Problem gambling and mental health conditions like depression and anxiety don't simply coexist — they feed each other in a cycle that researchers describe as reciprocal. Understanding which came first, and why, matters a lot for anyone trying to make sense of what they're experiencing.

How common is the overlap?

A meta-analysis of population-representative samples found that the highest mean prevalence of psychiatric disorders among problem gamblers — beyond nicotine dependence — included substance use disorder at 57.5%, mood disorders at 37.9%, and anxiety disorders at 37.4%. That's not a small overlap; it's the norm rather than the exception. The prevalence of mood disorders and anxiety disorders was found to be more than three times higher in problem gamblers compared to non-gamblers.

Depression specifically shows a stark pattern. Research has found roughly a three-times higher probability of major depression or dysthymia among problem gamblers, while rates of generalised anxiety disorder, panic disorder, and specific phobias were also over three times higher.

Which comes first — and does it matter?

This is where the picture gets genuinely complicated. The relationship runs in both directions. Among people with lifetime comorbidity of pathological gambling and other psychiatric disorders, the onset of mood disorder (65.1%), anxiety disorder (82.1%), and substance use disorder (57.4%) was reported to be earlier than the onset of pathological gambling. In other words, for many people, anxiety or depression was already present before gambling became a problem — suggesting those conditions can be a risk factor, not just a consequence.

But the reverse is equally real. People with problem gambling are more likely to feel anxious or depressed, and while gambling may start as a way to cope, it often makes mental health worse over time. Losses, shame, secrecy, and financial pressure all compound existing distress. Depression and anxiety in disordered gamblers were found to increase the likelihood of further health problems including sleep disturbances, which are associated with risk behaviours and in severe cases, lethal suicide attempts. That last point is serious — problem gambling carries real mental health risk beyond mood alone.

The coping trap

One of the most important practical insights from the research is that gambling often starts as self-medication. Stress from financial pressure, discrimination, or other life difficulties can affect how people use gambling — some use it as a way to cope with stress or isolation. The catch is that relief is temporary and the underlying condition remains untreated, while the harms of problem gambling layer on top of it.

Research now highlights the reciprocal relationships between gambling disorder and conditions like substance use, mood and anxiety disorders — meaning that treating just one side of the equation often isn't enough. Effective care tends to address both the gambling behaviour and the co-occurring mental health condition together.

Getting help in Ontario

Because the conditions are so intertwined, Ontario's support system is deliberately built to handle them together. ConnexOntario can connect you with gambling counselling, support groups, mental health services, or crisis support, with options for in-person, phone, or online contact — all free and confidential. The Centre for Addiction and Mental Health (CAMH) also provides specialized services for Ontarians whose gambling has led to difficulties in their life, including relationships, finances, and self-care.

If you're playing on a regulated Ontario site (look for the iGaming Ontario and BetGuard logos as confirmation it's licensed), built-in tools like deposit limits and self-exclusion through BetGuard (betguard.ca) are available if you want to step back. Anyone who suspects their gambling is tied to anxiety or depression — or who just wants to talk it through — can reach ConnexOntario 24/7 at 1-866-531-2600, by text, or by chat. The service covers gambling, mental health, and addiction together, which is exactly the right scope for this kind of problem. You need to be 19+ to gamble legally in Ontario, and that same age threshold applies to registering with any licensed operator.
