Does narcissism start in childhood? The childhood origins of personality disorders

Narcissism is a type of personality disorder characterised by a heightened need for admiration and a lack of empathy for others. But how does narcissism develop – and does it always stem from childhood?

Personality disorders, such as narcissism, are complex conditions where someone thinks, feels, behaves or relates to others in a way that significantly differs from the average person. And when it comes to understanding how and why personality disorders develop, a person’s childhood might hold some clues.

‘Personality begins developing long before we have the language to describe who we are,’ explains chartered child & educational psychologist, Jemma Anderson. ‘From our earliest relationships, children are learning not only what other people are like, but what they themselves are like in relation to other people: am I worthy of attention? Are my feelings important? Can I make mistakes and still be loved? Do I need to achieve, please or impress others to feel valued?’

‘These experiences become part of the developing story a child carries about themselves and their place in relationships,’ Jemma continues. ‘While childhood does not determine who we will become, it can leave us with patterns, beliefs and expectations that continue to shape how we see ourselves and other people long after childhood has ended.’

‘This does not mean that a particular childhood experience inevitably leads to a particular personality or mental health presentation,’ she adds. ‘Personality is shaped by many factors, including temperament, biology, relationships, environment and experience. But childhood does provide some of the foundations on which later patterns are built.’

Understanding developmental pathways in childhood

As a child grows up, they begin to make connections between certain behaviours and consequences. ‘For some children, love and approval become closely tied to achievement, status or being exceptional. A child may learn that being admired brings connection, while vulnerability, failure or ordinary needs are met with criticism, disappointment or withdrawal,’ Jemma explains.

‘Over time, they may come to rely heavily on external validation to maintain a sense of worth,’ she adds. ‘Research has found that parental overvaluation, by means of telling a child they are more special and more entitled than others, predicted the development of narcissistic traits over time, independently of parental warmth. Children, it seems, believe it when they are told they are exceptional. And that belief can become a fragile foundation.’

‘For others, the experience may look very different,’ Jemma continues. ‘A child who repeatedly feels rejected, humiliated, unseen or emotionally unsafe may develop a deeply fragile sense of self. Research examining childhood emotional neglect has found an association with the later development of personality disorder in adulthood. What can look like arrogance, entitlement or a need to control others in adulthood may sometimes sit alongside profound insecurity and an overwhelming difficulty tolerating shame.’

Does narcissism begin in childhood?

So, if your personality largely develops in childhood, does that mean disorders such as narcissism form during these early years too? ‘Narcissism refers to a pattern of relating to others that involves a heightened need for admiration, difficulty acknowledging vulnerability, and challenges with genuine empathy,’ Jemma explains. ‘These are not considered as a character flaw, but as a way of relating to oneself and others that can serve an understandable psychological function.’

‘Narcissistic traits exist on a spectrum,’ she adds. ‘Although it is important not to reduce narcissism to having had a difficult childhood, the presentations of both grandiose narcissism (appearing confident, dominant and self-assured) and vulnerable narcissism (appearing deeply insecure, and sensitive to criticism and shame) have roots in early relational experiences.’

Why do children develop personality disorders?

It’s important to remember that personalities – and by extension, personality disorders – are incredibly complex and can be influenced by several factors. ‘Personality development cannot be explained by one parenting style or one childhood experience,’ Jemma explains. ‘Personality disorders, such as narcissism, involve enduring patterns in how someone experiences themselves, regulates emotions and relates to other people, and their development is influenced by multiple biological and environmental factors.’

‘What a developmental lens can offer is an understanding of the function behind some of these patterns,’ she continues. ‘For example, a child who learns that being vulnerable is dangerous may grow into an adult who struggles to acknowledge weakness. A child who experiences relationships as conditional may become highly sensitive to rejection. Or, a child who has little opportunity to develop a secure, stable sense of self may look outside themselves for reassurance, admiration or control.’

‘Understanding these origins does not excuse harmful behaviour,’ Jemma adds. ‘It gives us a compassionate way of making sense of how it may have developed in the first place.’

Understanding the role of childhood in mental wellbeing

Whether we are exploring the childhood origins of anxiety, OCD or personality disorders, Jemma explains that there is always a common thread running through each. ‘The mind is always trying to protect us,’ she explains. ‘Anxiety protects us from threat. Compulsions protect us from uncertainty. Narcissistic patterns protect us from shame and vulnerability.’

‘These patterns can cause profound distress and harm, but they are not evidence that someone is fundamentally broken,’ she adds. ‘They are signs that a developing mind did what it could with what it had available. Understanding this with curiosity rather than judgement is often where something begins to shift.’
