An insecure attachment style is characterized by difficulties in relationships and maladaptive beliefs about the self and others.
Insecure attachment styles typically form in early childhood as a result of the caregiver-child bond. In essence, how a child perceives their needs to be responded to and met by their caregiver(s) forms an internal working model of relationships and themselves. This mental representation of relationships continues to shape our interpretations of relationships as we develop into adulthood.
If you’re wondering what insecure attachment is, how it develops in childhood, and how attachment insecurity continues to affect us as adults, this article contains all the information you need.
Attachment theory is a model of socio-emotional development which originated initially from the work of John Bowlby in the 1950s, as he posited that emotional problems cannot be solely attributed to internal processes. Instead, Bowlby proposed that how a child interacts with their environment in their early years – and specifically the caregiver-child bond – affects a child’s emotional health and development. Mary Ainsworth expanded on the model, especially with her contributions to the categorizations of the attachment styles, which were originally known as secure, resistant, and avoidant. Mary Main, a PhD student of Ainsworths, noted a distinct category of children who didn’t fit within these previous classifications, hence another category was devised – the disorganized attachment style.
Although the core constructs of attachment theory were formed between the 50s and 70s, the field of attachment continues to expand every day through social, neurological, and psychological research.
The insecure attachment styles are currently classified as:
| Attachment Style | In Childhood | In Adulthood |
| Insecure | Anxious-ambivalent | Anxious-preoccupied |
| Insecure | Anxious-avoidant | Avoidant-dismissive |
| Insecure | Disorganized | Fearful-avoidant |
In general, attachment styles are seen as a spectrum or dimensions:

Attachment styles develop as a response to the bond we form with our primary caregiver(s) during the main formative period of childhood (typically the first eighteen months to two years of life). Through how parents or caregivers meet their child’s needs, the child forms an internal working model of relationships, including expectations about the world and the people in it.
Secure attachment develops when a child perceives their caregiver to be sensitive and attuned to their needs. As a result, they feel validated, supported, loved, and safe to explore their environment with their safe base (their caregiver) nearby.
In contrast, an insecure attachment style can form when a child perceives their needs to be rejected or inconsistently met – or in chaotic situations in which they feel fear. We’ll discuss the varying circumstances which lead to insecure attachment next.
Insecure attachment can develop under the following conditions during the formative period of development (up to the first two years of life).
The manner in which the child’s needs are met leads them to feel like there’s an incoherence; sometimes their caregivers are responsive and attuned, and sometimes they’re absent or punitive. This inconsistency can be confusing for the child, as they end up feeling that their caregivers are ultimately unreliable. To maintain proximity to their caregiver, their attachment system becomes overactive, leading to emotional outbursts and clingy behaviors.
The child feels that their needs, particularly emotional ones, are being rejected or ignored. They may feel that they are not appreciated or understood for who they are. To maintain proximity to caregivers, they shut down their attachment system and develop a premature sense of self-reliance.
This sense of fear can come from alarm-inducing situations, such as traumatic events (for example, a caregiver acting chaotically). However, a sense of fear can also arise from situations that induce feelings of rejection or neglect, or ones that result in the feeling of being unloved or unprotected.
Due to the unique circumstances that lead to the development of the types of insecure attachment, each style leads to specific characteristics in children.
The Strange Situation experiment allowed for researchers (and subsequent professionals) to identify specific characteristics and patterns of behaviors in children with different insecure attachment styles.

These behaviors or characteristics are coping strategies designed to manage the emotions around the core beliefs and internal working models that these styles lead to.
If intervention strategies are not implemented to help a child shift towards more secure attachment, children risk carrying insecure attachment styles and internal working models into adulthood and relationships.

Unless strategies are implemented to heal the attachment wounds that develop in childhood, children with an insecure attachment style risk continuing the same pattern of thinking and behaving into adulthood.
As a consequence, insecurely attached adults typically have…
These issues make initiating and maintaining meaningful relationships difficult, whether these relationships are romantic, familial, friendships, or workplace. However, each of the insecure attachment styles are associated with specific patterns of thinking and acting, which we detail next.
Fear of abandonment or rejection in relationships is the driving force behind the thoughts

and actions of an adult with the anxious attachment style. This fear results in a hypersensitive nervous system, resulting in an overactivation of emotions, as well as hypervigilance for something going wrong – especially in relationships.
In addition to these traits, the following are also signs of anxious attachment in adults:
For someone with avoidant attachment, avoidance of intimacy and vulnerability is driven by an underlying fear of rejection. Due to a childhood in which they perceived their needs to be rejected, they deny their need for emotional closeness and shut down their attachment system, downplaying or dismissing emotions. People with this style are typically highly independent and self-reliant, often focusing on personal achievements rather than relationships. If they perceive someone to be pushing for increased intimacy, they may withdraw from or sabotage the relationship.
In addition, the following are traits of the avoidant attachment style in adults:
Known as disorganized attachment in children, fearful avoidant attachment is characterized by incoherent behaviors in relationships. This is because people with this attachment style often have both an over- and under-sensitive nervous/attachment system. They deeply desire love, but are also intensely fearful of being hurt by people they care about. Therefore, they are consistently seeking intimacy and validation, but also pushing it away as they perceive it as a threat to their safety.
The following behaviors are also characteristic of the fearful-avoidant attachment style in adults:

Although attachment styles are considered to be stable traits, they are nevertheless possible to change. With the right awareness, understanding, and strategies, anyone can transition from an insecure attachment style to “earned” secure attachment.
So, if you’re wondering how to heal insecure attachment, the following tips can help.

The best way to earn a secure attachment style is in a therapeutic relationship with a trained mental health professional. This is a safe environment in which someone with insecure attachment can process their experiences, facilitating trust, self-awareness, understanding of thought and behavioral patterns, emotion regulation, and personal growth. Furthermore, throughout the process of therapy, someone with an insecure attachment style will learn how to transition these skills to “real-world” relationships.
Research indicates that we cannot move on from the past without first recognizing the impact it has had on our lives. You can gain new perspectives by reflecting on your past experiences and processing the emotions associated with your insecure attachment style. Our workbooks are excellent tools for enhancing understanding and also work as useful therapy aids.
Adults with insecure attachment retain an internal working model of relationships from childhood. This internal working model drives certain maladaptive beliefs about how relationships work, and how the individual will be treated within them. Therefore, someone with insecure attachment may attempt to cope with limiting beliefs by avoiding emotional expression, through maintaining constant proximity, or even by avoiding relationships in general.
The good news is, if you’re wondering how to deal with an insecure attachment style, it’s possible to challenge limiting beliefs by identifying and learning how to disagree with them. You can do so by finding evidence to disprove them and applying logic to the situation at hand. The following are examples of how to do this.
| Belief | Challenge |
| If I allow someone to get close to me, they’ll hurt me. | Have all my relationships ended in pain? Vulnerability allows for real connection, yes, there’s a risk, but the benefits are worth it. |
| If they really loved me, they’d know what I need and want without having to tell them. | Is it fair to expect people to be mind readers? Clear communication is key to healthy relationships, so how can I express my needs more openly? |
| f the person I care about doesn’t text me back, they’re probably thinking of leaving me. | This person has never given a true indication that they might leave me. They might be busy at the moment, but they’ll get back to me as soon as they can. |
Alternative support figures (someone other than your primary caregiver), such as a grandparent, close friend, or romantic partner, may be able to offer the emotional support insecure attachers need to earn security. Evidence in the area suggests that these support figures do so through listening to their loved one when they are upset and helping them in times of distress. Such encounters facilitate the idea that others can be trusted, allowing someone with insecure attachment to learn that they can finally rely on others to meet their needs.
If you can’t think of anyone who could serve as an alternative support figure, the therapeutic relationship can help you learn these skills.
Many people wonder how to deal with an insecure attachment style without fully understanding the differences between these styles and how they develop. The types of insecure attachment are specific to the unique circumstances a child experiences, and can persist into adulthood unless effective intervention strategies are employed.
However, even if you have an adult insecure attachment style, it’s still possible to heal with the right information, support, and techniques. Trying therapy, learning about your attachment style, challenging limiting beliefs about relationships, and finding alternative attachment figures can all serve to help you on this journey.
Attachment may be defined as “a lasting connectedness between human beings,” but this doesn’t mean that your attachment style is permanently fixed. You may not be able to change your past, but you can target your present for a brighter, more promising future.
