Beyond the gambler: who else feels the ripples? It’s never just one person

Think of someone whose gambling is causing harm to themselves. Now picture the people around them: the partner worrying about the bills, the children picking up on tension at home, the sister who keeps lending money, the colleague who senses something is wrong.

Gambling harm spreads. It can bring money troubles, strained relationships, anxiety and poorer health to people who have never placed a bet themselves.

Yet most research has looked at a small circle: partners and close family, usually those who have asked for help. Even the labels used to describe those affected, like ‘concerned significant others’, can miss people who struggle quietly or don’t see themselves as ‘affected’ at all. So, as part of our UKRI-funded project, we asked a simple question: who actually gets hurt by someone else’s gambling?

Thinking in ripples

We carried out a literature review of research published since 2010 (159 studies in all) but quickly encountered a problem. Studies used different labels and focused on different groups, so they were hard to compare.

So, we borrowed an idea from ecological systems theory. Imagine gambling harm as a stone dropped into a pond: the ripples spread outwards, reaching some people more directly than others.

The closer the ring, the more someone tends to share daily life, money and responsibilities with the person who gambles.

The further out, the less we know

Most research focuses on those in Zone 1, especially partners and children. Zone 2 is much thinner, and those in Zone 3, including friends, are barely studied at all. We also know very little about how gambling harm plays out in workplaces, between lenders and borrowers, or across whole communities.

Real life is messier than a diagram

We didn’t just test the zones against the research. We also shared them with our lived experience panel: people who have been affected by someone else’s gambling, and asked what they made of them.

The map has two key nodes: their mum, and themselves. Around them sit people our zones would expect, like brothers and sisters, neighbours, employers and loan companies. But others are easy to overlook: school staff, medical professionals, even an amateur dramatics company.

The ripples don’t only spread from the person who gambles. They spread from the people around them too.

How to map who is affected?

Between the panel and the evidence, five things stood out that neat rings can’t capture on their own.

1. Relationships don’t come with tidy labels. An ex-partner may still share parenting or money with the person who gambles. An adult child might move back home and become a carer. In-laws and step-relatives can be deeply involved too.

2. Same zone, different story. Two people under one roof can be harmed in very different ways. It depends on things like whether the person gambling seeks help, when the exposure began and who carries which responsibilities.

3. Lives change. People move in and out, separate, and take on caring roles. A break-up can end living together without ending the debts or the heartache.

4. Ties can matter more than distance. A shared mortgage, joint finances or ongoing care of those living apart may shape harm more than a family label or an address.

5. ‘Gambler’ and ‘affected other’ can be the same person. Someone harmed by another’s gambling may later develop problems of their own or live with both at once.

A map, not a set of boxes

If we only look at the person gambling, or even just their household, we miss a lot of people who are harmed. The zones aren’t about sorting people into fixed categories. They’re a map. They help us spot whose stories are missing and ask better questions about how harm spreads and shifts over time, so that research and support reach everyone caught in the ripples.
