Traumatic bonding, also referred to as trauma bonding, is the process of an abuse victim developing a strong emotional bond with the perpetrator of the abuse (not with other survivors of the same abuse). The two main factors that contribute to the establishment of a trauma bond are a power imbalance in the relationship (e.g., whether the abuser has control over the victim in some way) and intermittent rewards and punishments. Intermittent rewards and punishments means that the abuser will be violent or cruel one day, and then be kind or loving another day; the victim endures the abuse in the expectation that the abuse will be temporary, albeit in a recurring cycle of abuse that predictably returns to abusive behavior.
Trauma bonding is not an emotional bond between survivors of a shared traumatic experience. Trauma bonding can occur within abusive romantic relationships, platonic friendships, parent-child relationships, incestuous relationships, cults, hostage situations, sex trafficking (especially that of minors), hazing or tours of duty among military personnel.
Trauma bonds are based on terror, dominance, and unpredictability. As the victim develops a stronger emotional bond with an abuser, it can lead to cyclical patterns of conflicting emotions in the victim. Frequently, victims in trauma bonds do not have agency, autonomy, or an individual sense of self. Their self-image is an internalization of the abuser's conceptualization of them.
Trauma bonds have severe detrimental effects on the victim. Some long-term impacts of trauma bonding include remaining in an abusive relationship, adverse mental health outcomes like low self-esteem and negative self-image, an increased likelihood of depression and bipolar disorder, and perpetuating a generational cycle of abuse. Victims who develop trauma bonds are often unable or unwilling to leave these relationships. Many abuse victims who experience trauma bonding return to the abusive relationship.
The concept was described by psychologists Donald Dutton and Susan Painter in the 1980s.
Recent developments and contemporary research Weaponized attachment Weaponized attachment is a pattern of manipulation in which an emotional bond, formed through shared trauma, emotional vulnerability, and intense affection, is deliberately created then exploited to control another person. By recognizing that abusers intentionally cultivate then exploit emotional attachment, Mags Lesiak reconceptualizes trauma bonding as a strategic system of coercive control rather than a victim's psychological response to trauma. The emotional attachment is maintained through intermittent reinforcement by alternating care and cruelty, described as a "two-faced soulmate" profile in which perpetrators combine intense affection with sudden withdrawal, secrecy, or hostility to create psychological captivity even without physical force.
Weaponized attachment shifts the focus of trauma bonding to the intentional actions of the perpetrator and has implications for policy and frontline practice. It is argued that risk tools measuring domestic partner violence need to consider coercive control as a mechanism of abuse with or without recent physical violence. The framework also suggests that professionals in mental health and social work should be trained to recognize the "two-faced soulmate" perpetrator profile and their intentional actions and use a weaponized attachment lens to place responsibility on the perpetrator's manipulations rather than the victim's psychology.
Context In the 1980s, Donald G. Dutton and Susan L. Painter explored the concept of traumatic bonding theory in the context of abusive relationships and domestic violence. This work was then further studied in the contexts of parent-child relationships, sexual exploitation, and more. Patrick Carnes described trauma bonding as "the misuse of fear, excitement, sexual feelings, and sexual physiology to entangle another person." Traumatic bonding is also described as "[a] strong emotional attachment between an abused person and his or her abuser, formed as a result of the cycle of violence." Carnes also studied traumatic bonding theory in the context of betrayal, which involved the exploitation of the victim's trust and/or sense of power by the abuser.
Establishment Trauma bonds are formed in abused-abuser and/or victim-victimizer dynamics. A victim can form a trauma bond with an abuser in the presence of a perceived threat from the abuser. Trauma bonds also form when the victim believes the abuser will follow through with a threat, when the victim perceives some form of kindness from the abuser, when the victim is isolated from outsider perspectives, and when the victim perceives a lack of ability or capacity to leave the situation.
The first incident of abuse is often perceived as an anomaly, a one-off instance occurring at the beginning of a seemingly healthy and positive relationship that is often not very severe. Furthermore, the expression of affection and care by the abuser following the incident pacifies the victim and instills in them the belief that the abuse is not recurring. However, repeated instances of abuse and maltreatment later generate a cognitive shift in the victim's mind: that preventing the abuse is not in their power. When the inability to escape the abuse becomes apparent, the emotional trauma bond is already strong.
Two main factors facilitate forming and continuing a trauma bond: a power imbalance and intermittent reinforcement.
Power imbalance For a trauma bond to persist, a power differential must exist between the abuser and the victim such that the abuser is in a position of power and authority and the victim is not. Inequality in power can produce pathologies in individuals that can fortify the trauma bond. Upon experiencing intermittent punishment from the abuser or dominant individual, who is in a position of high power, the victim may internalize the abuser's perception of themselves. This may result in a tendency for the victim to blame themselves in situations of violence perpetrated by the abuser, which can negatively impact the victim's self-concept.
A negative self-appraisal can maximize the emotional dependency on the abuser and the cyclical nature of this dependency. Negative self-concept can eventually lead to the formation of a strong emotional bond from the victim to the abuser (i.e., to the person who is in a position of power and authority from the person who is not). Furthermore, physical, emotional, and sexual abuse can be used to maintain the power differential. This dynamic is also maintained via the interaction of the abuser's sense of power and the victim's sense of powerlessness and subjugation.
Intermittent reinforcement Intermittent reinforcement of rewards and punishments is crucial to establishing and maintaining a trauma bond. In trauma bonding, the abuser intermittently maltreats the victim through physical, verbal, emotional, and/or psychological abuse. This maltreatment is interspersed with positive behaviors like expressing affection and care, showing kindness, giving the victim gifts, and promising not to repeat the abuse. Alternating and sporadic periods of good and bad treatment serve to reinforce the victim intermittently.
The pervasiveness of learning something through intermittent reinforcement can be elucidated by drawing from learning theory and the behaviorist perspective. In the presence of an aversive stimulus, reinforcement through rewards in unpredictable ways is a key component of learning. When the learner is unable to predict when they will get the reward, learning is maximized. Similarly, the intermittent expressions of affection and care are unexpected, and the inability to predict them makes them more sought after. Intermittent reinforcement produces behavioral patterns that are tough to terminate. Thus, they develop incredibly strong emotional bonds.
Maintenance A trauma bond can be maintained by keeping the power imbalance and the intermittency of abuse intact.
Trauma bonds can also be maintained if the victim is financially dependent on the abuser or has some investment in the relationship, such as a child with the abuser.
Cognitive dissonance theory can also explain the maintenance of a trauma bond; it postulates that when individuals experience a conflict between their beliefs and actions, they are motivated to reduce or eliminate the incongruence to minimize the psychological discomfort. In this vein, victims may distort their cognition about the trauma and violence of the relationship to maintain a positive view of the relationship. This can involve rationalizing the abuser's behavior, justifications, minimizing the impact of the abuser's violence, and/or self-blaming.
Furthermore, research shows that the memory of instances wherein abuse was experienced is dissociated or state-dependent, meaning that the memories of abuse only fully resurface when the situation is similar in intensity and experience to the original situation of terror.
If and when the victim finally decides to leave the abusive relationship, the immediate relief from the traumatizing violence will begin to abate, and the underlying, deep attachment formed from intermittent reinforcement will begin to surface. This current period of vulnerability and emotional exhaustion will likely trigger memories of when the abuser was temporarily affectionate and caring. In the desire to receive that affection once more, the victim may try to return to the abusive relationship.
Strong social support can be a protective factor in preserving the victim's functioning and providing a buffer in traumatic situations.
The role of attachment John Bowlby maintained that secure attachment was an evolutionary human need that superseded even the need for food and reproduction. Attachment has been explored in depth in caregiver-child dynamics, but recent research has shown that the principles that explain attachment between caregivers and infants can also explain attachment throughout one's life span, specifically in the context of intimate relationships and romantic bonds.
Attachment bonds formed during early life lay the foundation for interpersonal relationships, interactions, personality characteristics, and mental health in the future. Infants usually form attachments with their parents or immediate caregivers. Harlow's research on monkeys shows that infant monkeys form attachment bonds even with abusive mothers (in the experimental setup, the abusive 'mother' was a monkey made out of fabric who delivered mild shocks to the infant monkey or flung the infant monkey across the arena).
These findings also apply to human attachment bonds. Even in situations where immediate caregivers are abusive, human infants still tend to attach to them; rejection from a caregiver only enhances the efforts to increase proximity to them and establish an attachment bond with them.
Furthermore, in situations of danger, humans seek increased attachment. When ordinary pathways of attachment are unavailable, people tend to turn to their abusers. This leads to strong bonds and deep emotional connections with abusers. This attachment—both to abusive caregivers and to other abusers in the absence of a main caregiver—may be adaptive in the short run as it may aid survival. But in the long run, this attachment is maladaptive and can lay the foundation for, increase vulnerability to, and even directly lead to trauma bonding.
Stockholm syndrome The concept of trauma bonding is often conflated with Stockholm syndrome. Although there are overarching similarities between the two, especially in the context of developing an emotional bond with one's abuser, trauma bonding and Stockholm syndrome are distinct from one another. The main difference is the direction of the relationship.
