Trauma Bond: What It Is, What the Research Actually Found, and How to Break One

A trauma bond is a strong emotional attachment to someone who is hurting you. It tends to form when the harm comes in cycles, cruelty followed by warmth, and when that person holds more power than you do. The result is a pull that can feel like love and makes leaving, or staying gone, painfully hard. Researchers call it traumatic bonding. It is not a diagnosis, and it is not a sign of weakness. It is a predictable response to a particular kind of relationship, and the research has one genuinely hopeful finding about it: the pull fades with time.

If you are reading this because you miss someone who hurt you, or cannot understand why you keep going back, you are describing something researchers have studied for more than forty years. What follows is what a trauma bond feels like, what the research actually found, which popular claims it does not support, and what helps.

What a trauma bond feels like

From the inside, a trauma bond rarely feels like “trauma”. It feels like loving someone more than makes sense. Common experiences include:

• Missing the person intensely, even though you know they hurt you, and even long after it ended.
• Remembering the good times far more vividly than the bad ones.
• Believing that the kind, loving version of them is the real one, and that the cruelty is a temporary lapse.
• Defending them to friends and family, or hiding what happens.
• Going back, or wanting to, after deciding to leave.
• Feeling that being without them is worse than what they did.

That last one is not an exaggeration. In a 2026 Cambridge interview study of 18 women who had experienced repeated domestic abuse, many compared the pull toward their former partner to an addiction. One described the break-up as “like coming off the drugs” and said, “Being without him was worse than the abuse.” She also said that after a few months, the pain stopped. The US National Domestic Violence Hotline lists similar signs in its guide to trauma bonds, including obsessing about people who have hurt you, continuing to seek contact with someone you know will cause you more pain, and staying loyal to people who have betrayed you.

“Trauma bond” and “traumatic bonding”: same idea, different names

“Trauma bond” is the everyday phrase. The research term is traumatic bonding, introduced by psychologists Donald Dutton and Susan Painter in the early 1980s to explain why women in abusive relationships often felt deeply attached to their partners. Patrick Carnes’s 1997 book The Betrayal Bond later applied the idea to a much wider range of exploitative relationships, from incest and domestic violence to workplaces and religious groups.

The research base is small. A PubMed search in October 2026 returns 7 records for “traumatic bonding” and 19 for “trauma bonding”, and many of the latter come from research on survivors of sex trafficking rather than romantic relationships. That matters, because most of what you will read online about trauma bonds in relationships, including stage models and long lists of symptoms, goes well beyond what has actually been studied.

What the research actually found

The foundational study is still the most useful one. In 1993, Dutton and Painter assessed 75 women who had recently left abusive relationships (50 of which had involved physical violence), once just after separation and again six months later. They found:

• Intermittency mattered. The more extreme the swings between maltreatment and better times, the stronger the women’s attachment to their former partner.
• Power mattered. Bigger power differences between the partners went with stronger attachment.
• The relationship explained a lot. Total abuse, its intermittency and the power difference together accounted for 55% of the variation in attachment six months later.
• The attachment faded. After six months, attachment had decreased by about 27%.

Two cautions. It is one study of 75 women, from 1993, based on interviews and questionnaires. And it shows what went together, not what caused what. Still, its central idea underpins the later research, and it gives a far more precise picture than most popular accounts: it is the pattern of the relationship, alternating harm and warmth inside an imbalance of power, that the research links to the bond, not some flaw in the person who feels it.

Later research has added two things. A 2023 study of 354 people currently in abusive relationships found that stronger traumatic bonding went with more PTSD symptoms. And the 2026 Cambridge study argues the bond is often something the abusive partner actively builds, through grooming and alternating cruelty with care. In the authors’ words, “trauma bonding isn’t a symptom of weakness – it’s a strategy of control.” That is a qualitative study of 18 women in the UK who had left their abusive partners, so it describes experiences in depth rather than how common they are.

Trauma bond vs love

This is often the real question. Nobody has a test that separates the two, and a trauma bond can include genuine love. What the research points to is the shape of the relationship around the feeling:

A useful question to sit with: if the good times stayed exactly the same, but you knew the bad times would never end, would you still choose this? A trauma bond tends to live on the hope that the warm version is coming back.

The seven stages of trauma bonding: where that model comes from

Search for trauma bonds and you will quickly find “the seven stages”: love bombing, trust and dependency, criticism, gaslighting, giving up, losing yourself, and addiction to the cycle. This model circulates on therapy-practice and self-help websites. We could not find it in any peer-reviewed study, and no research has tested whether trauma bonds move through stages in a fixed order.

Some of the stages describe real behaviours that people do experience. The problem is the certainty. A neat sequence suggests that everyone’s relationship follows the same script, and that you can locate yourself on it. Real relationships are messier, and the research describes a pattern (intermittency and power), not a timeline.

Trauma bonding is not Stockholm syndrome

The two are often treated as the same thing. They should not be. A 2008 systematic review of Stockholm syndrome found only 12 papers that met its criteria, mostly case reports, with no validated diagnostic criteria and no place in any international classification system. Stockholm syndrome is a media label for hostage cases, not an established condition.

More recently, researchers have proposed replacing the term with appeasement: the idea that survivors may appear emotionally connected to the person harming them as a way of calming that person and staying safe. It is a proposal in a review article, not a tested finding, and it describes the outward behaviour more than the inner attachment. But it is a useful reframe. What looks like loyalty from the outside can be a survival strategy. If that resonates, our article on the fawn response looks at appeasing under pressure in more detail.

Who it happens to, and why it isn’t weakness

Anyone can form a trauma bond. The research points first at the relationship: intermittent harm and a power imbalance. Some people do appear to be more at risk. In the 2023 study of 354 people, childhood maltreatment and attachment insecurity both predicted stronger traumatic bonding, and the link from childhood maltreatment was stronger in people with more attachment insecurity. The authors describe it as the first study to examine a complex model of risk factors, which tells you how young this research is. These are risk factors in one snapshot study, not causes, and plenty of people with neither history still form trauma bonds.

If the fear of losing people and a strong need for reassurance feels familiar more broadly, our guide to anxious attachment style covers that pattern.

Not everyone thinks the concept helps. David Mandel of the Safe & Together Institute, which trains professionals on domestic abuse, argues that the label can focus professionals on the survivor instead of the perpetrator, and can blame survivors for the failures of others to intervene. It is a fair warning. A trauma bond explains why leaving is hard. It does not explain away the other person’s behaviour, and it is not something you did wrong.

Trauma bonds outside romantic relationships

The same pattern of intermittent harm and unequal power can arise elsewhere. The research and clinical literature describe it in child abuse, intimate partner violence, human trafficking and hostage situations, and people also use the term for families, friendships, workplaces and controlling groups. The research on those everyday settings is thin, but the questions are the same: is there a cycle of harm and warmth, and does one person hold the power?

Breaking a trauma bond

Start with the honest part: no treatment has been tested specifically for trauma bonds. What follows draws on what the research describes and on the guidance of domestic abuse services, not on trials.

• Safety first. If there is any fear, threat or control, plan with a domestic abuse service before you change anything (contacts at the top of this page). That includes decisions about going no-contact. Separation does not always end the danger: a review of research on abuse after separation lists lethality among its consequences.
• Name the cycle. Write down what actually happens, the bad times as well as the good, with dates. Trauma bonds run on memories of the warm moments. A written record is harder for the bond to edit.
• Judge by behaviour, not promises. The Hotline puts it plainly: stop compromising truth for promises. Look at what has happened, not at what you hope will happen.
• Expect the pull, and let it pass. Missing them is not evidence that you should go back. It is the bond doing what bonds do. The Hotline suggests pausing to acknowledge it with something like “I love them, but I don’t want to love them”. You can notice the feeling and not act on it.
• Rebuild your world. Trauma bonds tend to shrink your life around one person. Reconnecting with friends, family and things you used to enjoy gives the attachment fewer places to hide.
• Get help for the trauma itself. Traumatic bonding goes with PTSD symptoms, and those have well-tested treatments. In the UK, NICE recommends trauma-focused therapies such as trauma-focused CBT and EMDR for PTSD. A therapist experienced with domestic abuse is the right fit.

Breaking a bond like this often comes alongside other patterns worth understanding, such as stonewalling used as punishment, or a habit of appeasing to keep the peace. And if you notice yourself drawn to similar relationships again, our piece on breaking repeating relationship patterns may help.

If you want somewhere to think things through between conversations with the people supporting you, aidx.ai, an AI coaching and therapy service, can help you notice the cycle, put words to what you feel and plan small next steps. It is AI, not a clinician, and it is not a replacement for a domestic abuse service or for help to leave safely.

Can a relationship recover from a trauma bond?

People ask this a lot, and it deserves a straight answer. No research has followed couples who tried to repair a relationship built on a trauma bond, so nobody can promise it works. A trauma bond forms around harm and unequal power. It cannot be fixed by the person on the receiving end loving better, trying harder or being more understanding.

Change, if it happens, has to come from the person causing the harm, and has to show up as sustained behaviour, not promises. Domestic abuse services also advise against couples therapy with an abusive partner, because abuse is not a relationship problem and what you say in session can be used against you afterwards. A domestic abuse service can help you weigh what real change would look like, and keep you safe while you decide.

Common questions

What is a trauma bond in a relationship?

It is a strong emotional attachment to a partner who is hurting you, usually formed through cycles of harm and warmth inside an imbalance of power. Researchers call it traumatic bonding. It explains why leaving, or staying away, can feel so hard.

How do you know you are trauma bonded?

Common signs are missing someone who hurt you, focusing on the good times, defending or hiding their behaviour, and going back after deciding to leave. There is no validated self-test. If several of these fit, and there is fear or control in the relationship, talk to a domestic abuse service.

What are the 7 stages of the trauma bond?

The popular list runs from love bombing through to addiction to the cycle. It comes from self-help and therapy-practice websites, not from research, and no study has tested it. The research describes a pattern of intermittent harm and unequal power, not a fixed sequence of stages.

How long does it take to get over a trauma bond?

There is no set timeline. In the one study that measured it, women’s attachment to an abusive former partner had decreased by about 27% six months after leaving. That means the pull fades measurably, but slowly, and for many people it is still present at six months. Be wary of anyone promising a fast fix.

Is a trauma bond the same as Stockholm syndrome?

No. Stockholm syndrome has no validated diagnostic criteria and rests mostly on case reports. Traumatic bonding has been studied in abusive relationships, though the research is still small. Some researchers now prefer the word appeasement for what used to be called Stockholm syndrome.

Is a trauma bond a diagnosis or a disorder?

No. It is a described pattern with a research name and a small evidence base. It is not in any diagnostic manual. The PTSD symptoms that often come with it can be diagnosed and treated.

Is there a trauma bond test?

Researchers use a questionnaire called the Trauma Bonding Scale for Adults, tested in young adults aged 18 to 29 in the US (619 people) and Kenya (538 people). It is a research tool, not a self-diagnosis quiz. Online trauma bond tests are not validated.

Is there a 12-step programme for trauma bond recovery?

Some exist, but none has been tested for trauma bonds. Peer support can help with isolation. For the trauma itself, evidence-based PTSD treatment and a domestic abuse specialist are the better-supported routes.

Can you have a trauma bond with a friend or a family member?

The term is used for any close relationship with cycles of harm and warmth and an imbalance of power, including families and friendships. Research outside romantic and trafficking settings is thin, but the same questions about pattern and power apply.

What is a “shared trauma bond”?

People sometimes use the phrase for closeness that forms between two people who went through something hard together, such as an accident or a crisis. That is a different, usually healthy kind of bond. It is not traumatic bonding in the research sense, which is attachment to the person causing the harm.

Is it a trauma bond with a narcissist?

Many people arrive at this topic with that word. A diagnosis of narcissistic personality disorder can only come from a clinician who has assessed the person. What the research on traumatic bonding points to is behaviour: cycles of cruelty and warmth, control and a power imbalance. You do not need to diagnose them to take that behaviour seriously.

What kind of therapy helps with a trauma bond?

No therapy has been tested for trauma bonds specifically. A therapist experienced with domestic abuse and trauma can help, and trauma-focused therapies have strong evidence for the PTSD symptoms that often come with traumatic bonding. If you are still in the relationship, a domestic abuse advocate can help you think about safety alongside therapy.
