Attachment Theory
What’s it all about anyway?
Early life experiences shape the way we understand relationships and what we need to feel safe and connected with other people. John Bowlby described how these early interactions form internal working models — mental representations of the self, other people, and the relationship between self and others. These models influence how we experience closeness, trust, and emotional connection throughout life.
Attachment patterns contain expectations and beliefs about the behaviour of others and the self, including our sense of lovability, worthiness and acceptability, as well as the emotional availability and reliability of those around us. These early relational templates can affect how we manage emotions, respond to stress, and seek support.
Attachment behaviour develops as a way for children to cope with anxiety and gain protection and care from their primary caregiver. Proximity and responsiveness provide opportunities for the child to learn about themselves, others, and relationships. Over time, these experiences become internalised and can shape patterns of relating well into adulthood.
Mary Ainsworth and Mary Main devised ways to explore these concepts through the Strange Situation Assessment (carried out with infants aged between 12 and 18 months) and the Adult Attachment Interview (AAI). Findings from this research led to the classification of attachment styles.
Secure Attachment develops when caregivers can respond consistently and sensitively to a child’s emotional needs. This supports the child in developing a positive view of themselves, social confidence, and the ability to manage a range of emotions. Securely attached adults often feel comfortable with intimacy and are able to seek support when needed.
Avoidant, Defended or Dismissing attachment may develop when caregivers feel uncomfortable with emotional closeness or become distressed around a child’s needs. The child may learn to become independent too soon, and emotional expression may be discouraged. In adulthood, this can show up as difficulty relying on others, minimising feelings, or pulling away when relationships feel too close.
Ambivalent, Dependent or Preoccupied attachment can develop when caregiving is inconsistent or frequently insensitive. The child may experience uncertainty about whether their needs will be met, leading to anxiety around abandonment and a strong desire for reassurance. Adults with this pattern may feel emotionally overwhelmed in relationships or fear being left.
A fourth style, identified by Mary Main in 1990, is Disorganised, Controlling or Unresolved attachment. In these situations, the caregiver may be experienced as frightening or unsafe. This can lead to confusion and difficulty regulating emotions or forming stable relationships later in life.
Importantly, attachment styles are not fixed. They are adaptive responses to early experiences, and with insight and support, they can change over time. In psychotherapy, exploring attachment can help make sense of recurring patterns in relationships — such as withdrawing, people-pleasing, fear of rejection, or struggling to trust others.
Often, attachment dynamics emerge naturally within the therapeutic relationship itself. Therapy can provide a safe and consistent space to explore these patterns with compassion, allowing new experiences of emotional attunement and security. Over time, many people develop what is known as earned secure attachment — a greater sense of safety, trust, and self-worth built through supportive relationships, including therapy.
Rather than labelling, attachment theory offers a gentle framework for understanding how early strategies helped you cope, and how therapy can support you in building healthier, more fulfilling connections.
