Secure Attachment: 9 Signs, Effects & How It Develops

What is an Attachment?

Almost immediately after birth, infants form an emotional bond with their caregivers. Psychologists refer to this human connection as an attachment and the primary caregiver as the attachment figure. Attachment in infants can significantly affect a child’s healthy development and has been studied extensively in psychology.

Attachment style in children

A child’s attachment style is the characteristic pattern they use to maintain attachment to their primary caretaker for safety and emotional needs.

Attachment styles typically develop in the first few months of life and have an influence on the way people relate to others throughout their lives.

There are four types of attachment in children​1​:

A father plays with his two kids on the couch.

Out of the four patterns of attachment, avoidant attachment, ambivalent attachment, and disorganized attachment are insecure attachment styles.

This attachment classification was used in a simulated laboratory setting, called the Strange Situation procedure created by psychologist Mary Ainsworth, to identify a child’s attachment type.

In this experiment, 1-year-olds would be briefly separated from their primary caregiver and exposed to a stranger.

This mildly stressful situation helped the researchers understand how secure an infant-caregiver bond was​2​.

Attachment theory, formulated by British psychologist John Bowlby in the 1970s, states that infants need a secure attachment bond with a primary attachment figure to develop a healthy internal working model of relationships.

Human beings of all ages, according to Bowlby, are happiest and at their best when they are confident that their trusted “special adult” stands behind them as their secure base if difficulties arise​3​.

From childhood into adulthood, attachment security is a powerful predictor of a child’s social and emotional outcomes later in life.

Attachment styles in adults

Scientists have found that attachment styles also apply to romantic relationships among adults.

The attachment styles in adult relationships roughly correspond to the four styles seen in the infant-parent attachment. 

They are​4​:

Adult attachment can be identified along two dimensions – anxiety and avoidance.

Generally, a secure attachment is associated with lower anxiety and avoidance, whereas an insecure attachment style with higher levels of anxiety and avoidance.

Among the four child attachment styles, secure attachment is believed to have the best characteristics of attachment.

What is secure attachment?

Secure attachment forms during child development when a child trusts that their caregivers can be relied upon to provide for their needs. Secure attachment styles tend to develop in children whose caregivers are warm and responsive. In the Strange Situation, a secure child shows signs of distress when separated from their caregivers, and happiness when they return. 

Secure infants have developed a strong emotional connection with the caregiver and a feeling of safety. 

Secure attachment relationships provide the infant brain with an optimal development environment.

An infant’s right brain has deep connections to the limbic and autonomic nervous systems. It is responsible for a child’s stress response and emotional development.

Signs of secure attachment in children

Children with secure attachment have the following characteristics:

  1. A secure child shows signs of distress when separated from their caregivers, and signs of happiness when they return to the Strange Situation. 
  2. They are able to compose themselves quickly on the return of their caregivers​5​
  3. They are able to trust that their caregiver is a dependable adult who can be relied upon for the baby’s needs​6​
  4. They feel free to explore their surroundings and return to their caregivers for comfort or assistance because they are the base of security.

Signs of secure attachment in adults

Characteristics of secure attachment style in adults include:

  1. Less hostile or prone to anger​7​
  2. Less anxiety​8​
  3. Better emotional regulation
  4. More positive self-view and higher self-esteem​9​
  5. Better mental health and less likely to develop psychopathology even in a high-threat environment​10​

Impact of Secure Attachment

Secure attachment is associated with many benefits.

Secure children tend to be

  1. More self-reliant and independent​11​
  2. More compliance and cooperation with the parent​12​
  3. Show higher academic performance​13​
  4. Better emotional regulation skills​14​
  5. More social skills and competence​15​
  6. Less social anxiety and more socially active​16​

Secure attachment comes with a host of social and emotional benefits in adulthood as well. 

Secure adults tend to be 

  1. Have higher self-esteem​17​
  2. more competent
  3. have a stronger sense of trust in close relationships than those with insecure attachment bond
  4. When coping with trust violations, they use more constructive strategies which are associated with happy, intimate, friendly, and healthy relationships​18​
  5. Have higher marital satisfaction​19​

Secure attachment – How it develops

Secure attachment forms when a child trusts that their caregivers can be relied upon to provide for their needs.

Research finds that even the subtlest shift in parental behavior can affect attachment.

Parents of children who are securely attached are typically sensitive and responsive to their child’s needs​20​.

When giving commands, they tend to use an affectionate tone of voice and use a gentler physical correction​21​.

They also communicate comfort visually and physically through a comforting type of body language​22​.

They show more positive emotions than negative emotions at home​23​. These parents are high in independence-encouraging and acceptance​24​.

In the Baumrind parenting style categorization, the authoritative parenting style is the best parenting style according to research and its characteristics match the requirements for creating a secure attachment.

To children who have been mistreated previously, it is particularly important to use empathic language, attentive eye contact, and supportive body posture​25​.

Final Thoughts on Secure Attachment

There is no perfect parent in this world.

Don’t despair if your child hasn’t developed a secure attachment.

Although attachment patterns remain largely stable across the lifespan, experiences in the early years of life have a critical role to play​26​ because attachment styles do change in response to major life events.

To start the secure attachment process, parents can make adjustments in daily life to help children develop security (or avoid attachment insecurity).

Adopt a sensitive and responsive parenting style.

You can also involve a mental health professional such as psychologist or therapist to help in challenging situations.
