Secure attachment is widely recognised as a cornerstone of psychological wellbeing and interpersonal harmony. Amir Levine, bestselling author of Attached, a leading authority in attachment theory, observes that positive interpersonal relationships that are founded on trust and mutual respect are a prerequisite for human flourishing.

From infancy to adulthood, individuals with secure attachment patterns tend to form healthier relationships, regulate emotions more effectively and navigate life’s challenges with greater resilience.

This article explores the development of secure attachment, its significance across the lifespan and how therapeutic approaches can support its cultivation.

Understanding attachment theory

Initially pioneered by John Bowlby (1969), attachment theory posits that the emotional bonds formed between infants and their primary caregivers serve as blueprints for future relationships. In his book, The Secure Base, Bowlby described attachment as an innate behavioural system designed to lay the foundations of ‘lasting psychological connectedness between human beings.’ Crucially, Bowlby observed that children who experience neglect or abuse are likely to develop insecure attachments throughout life.

Mary Ainsworth’s (1978) "Strange Situation" research expanded on Bowlby’s theory by identifying distinct attachment styles in infants: secure, avoidant, ambivalent (or anxious), and later, disorganised (Main & Solomon, 1990). These styles emerge based on the sensitivity and responsiveness of caregivers.

In secure attachment, caregivers are consistently responsive, attuned and emotionally available. This fosters a sense of safety and trust in the child, who learns that their needs will be met and that the world is generally a safe place. As Bowlby famously wrote:

“We are only as needy as our unmet needs.”

Characteristics of secure attachment

Children with secure attachment typically:

• Seek comfort from caregivers when distressed, and are easily soothed

• Use caregivers as a secure base from which to explore

• Display confidence in social interactions

• Exhibit balanced emotional expression and regulation

Secure attachment is not about perfect parenting but rather "good enough" caregiving, a term coined by the paediatrician and child psychiatrist, Donald Winnicott (1960). Winnicott, in his book, The Child, the Family, and the Outside World, encourages mothers and fathers to trust in their natural parental instincts. Occasional misattunements are inevitable, he observed, but what matters most is the caregiver’s capacity to repair and restore the connection.

Secure attachment in adult relationships

Securely attached adults tend to exhibit:

• A healthy balance between autonomy and intimacy

• Comfort with emotional closeness and vulnerability

• Positive self-image and a realistic view of others

• Effective communication and conflict resolution skills

• Capacity to offer and seek support when needed

According to Bartholomew and Horowitz (1991), adult attachment styles can be conceptualised along two dimensions: anxiety and avoidance. Secure individuals score low on both dimensions, indicating comfort with closeness and trust in others' availability.

The neurobiology of secure attachment

Secure attachment is associated with optimal functioning in brain regions related to emotion regulation, empathy, and social bonding. For example:

• The prefrontal cortex, which is often referred to as the brain's executive command centre, is involved in self-regulation and decision-making. Studies outlined by R. M. Sapolsky in his book, Behave, show that securely attached individuals have thicker prefrontal cortexes and less circulating stress hormones.

• The hypothalamic-pituitary-adrenal (HPA) axis, which governs the stress response, tends to be more regulated in those with secure attachment histories (Gunnar & Quevedo, 2007).

• Oxytocin, the so-called "bonding hormone," plays a key role in fostering trust and connection, and is released during nurturing interactions (Feldman, 2012).

Secure attachment thus provides a biological buffer against stress and promotes healthy interpersonal functioning.

Secure attachment and mental health

Secure attachment is linked with lower rates of anxiety, depression and relational dysfunction. In contrast, insecure attachment styles are often implicated in emotional difficulties and psychopathology. For instance:

• Avoidant individuals may struggle with intimacy and suppress emotional needs.

• Anxious individuals may exhibit dependency, fear of abandonment, and heightened emotional reactivity.

• Disorganised attachment, often resulting from trauma or neglect, is associated with dissociation, emotional dysregulation, and complex trauma.

A secure attachment pattern provides a protective factor, enhancing resilience and promoting adaptive coping strategies throughout life.

How secure attachment can be cultivated in adulthood

While early attachment experiences lay the foundation for future relational behaviours, attachment patterns are not set in stone – they are not ‘fixed.’ Dan Siegel, in his book, Pocket Guide to Interpersonal Neurobiology, suggests that the brain’s neuroplastic capabilities enable us to unlearn unwanted thought structures and behavioural patterns. For example, if a person is prone to forming anxious attachments, they can, with the right support network in place, ameliorate this unhealthy attachment style. But this is only half of the picture.

Neuroplasticity, of course, also allows for the ‘rewiring’ of new healthy thoughts and behaviours. As Siegel famously wrote, ‘where attention goes, neural firing flows, and neural connection grows.’ This quote emphasises the fact that we all possess the capacity to, if you will, train our brains to work with and not against us.

What follows is an outline of a range of methods and interventions that can be used to rewire old patterns.

1. Therapeutic relationships

One of the most powerful contexts for developing secure attachment is within a therapeutic alliance. A trained therapist can provide a reparative relational experience through:

• Attunement: Deep, empathic understanding and presence

• Consistency: Reliable boundaries and availability

• Repair: Acknowledging and working through relational ruptures

Attachment-Based Therapy, developed by David Wallin (2007), specifically focuses on transforming insecure attachment styles into more secure patterns through relational and reflective work.

2. Romantic relationships

Romantic partners can also act as attachment figures. When relationships are secure, they offer a safe space during distress and a secure base for exploration. It’s worth noting that one has to be careful to avoid becoming dependent on a partner. This can adversely impact the relationship. Amir Levine reminds us that a healthy relationship ‘attachment doesn’t mean losing yourself in someone else: it’s about finding a balance between closeness and individuality’ (Amir Levine). Relationship education, couples therapy, or simply cultivating emotional openness and mutual responsiveness can strengthen attachment security.

3. Self-reflection and mindfulness

Practices that amplify self-awareness – such as journaling and mindfulness meditation – can help individuals observe their attachment behaviours and make conscious choices. Mindful awareness allows for greater emotional regulation and empathy, both of which are central to secure relating (Siegel, 2007).

Furthermore, by enhancing self-awareness and developing an understanding of the different attachment styles, a person will become more acutely aware of their attachment orientation. In conjunction with an insight into these therapeutic interventions, that person will also be able to take active steps to transition to a healthy attachment type.

4. Parenting with sensitivity

For parents and caregivers, fostering secure attachment in their children requires responsiveness, emotional availability and reflective functioning. Circle of Security Parenting (Cooper, Hoffman, Powell & Marvin, 2013) is one evidence-based model that supports caregivers in understanding and meeting their children’s emotional needs effectively.

Secure attachment and coaching

In the coaching context, the presence of a secure, trusting relationship can enable clients to explore goals, challenges and emotional blocks more openly. Compassion-Focused Coaching, which draws from Paul Gilbert’s Compassion Focused Therapy (CFT), encourages emotional safety and self-compassion – elements that mirror secure attachment conditions.

Coaches who are attuned, non-judgmental and emotionally responsive can offer clients a corrective relational experience that may indirectly promote attachment security and self-trust.

Cultural considerations

Attachment theory, while robust, has been critiqued for its Western-centric assumptions. Rothbaum et al. (2000) argue that attachment behaviours vary cross-culturally and that notions of independence and emotional expression are not universal markers of security. For example, in collectivist cultures, secure attachment may manifest through interdependence and group harmony rather than autonomy.

Thus, while secure attachment appears to be a universal need, its behavioural expressions can differ based on cultural context.

Measuring attachment security

Attachment security can be assessed through:

• The Adult Attachment Interview (AAI): A structured interview that explores an individual’s early experiences and current relational patterns (George, Kaplan & Main, 1985).

• Self-report inventories: Such as the Experiences in Close Relationships Scale (ECR; Brennan, Clark & Shaver, 1998), which evaluates attachment-related anxiety and avoidance.

These tools are used in both research and clinical practice to inform understanding and interventions.

Conclusion

Secure attachment is a dynamic, relational state that supports sound mental health, emotional resilience and fulfilling relationships. While the seed of secure attachment is planted and nurtured during early caregiving, it can be developed and strengthened at any stage of life—the primary methods include meaningful connection, reflection and relational support.

Whether through therapy, intimate partnerships, or self-compassion practices, the journey toward secure attachment is both healing and transformative – offering individuals the inner security needed to thrive in an ever-changing world.
