Introduction
Adolescence is often portrayed as a turbulent and emotionally charged life stage—a period defined by internal conflict, heightened self-awareness, and the daunting task of identity formation. During this critical developmental window, individuals experience a range of physical, psychological, and social transitions that can provoke anxiety, confusion, and distress. Traditionally, such behaviours have been explained in biological or sociocultural terms; however, psychoanalytic theory provides an additional lens for understanding the inner experiences that fuel adolescent conduct. Among the leading contributors to this perspective is Anna Freud, whose work fundamentally altered how psychology conceptualises ego development and emotional regulation.
As the daughter of Sigmund Freud and a pioneer in her own right, Anna Freud advanced psychoanalysis by focusing on the mechanisms through which the ego protects itself from psychological discomfort. Her most influential text, The Ego and the Mechanisms of Defence (1936), systematically outlines how unconscious strategies—such as repression, regression, projection, and reaction formation—are employed by individuals to cope with internal conflict and external demands. While initially framed in the context of child development, these mechanisms are particularly salient during adolescence, when the ego is under renewed pressure from both revived infantile conflicts and new developmental tasks.
The value of Anna Freud’s theory lies in its ability to reframe what is often dismissed as “difficult” or “irrational” adolescent behaviour as understandable, even purposeful, responses to internal emotional turmoil. In doing so, her framework invites empathy, rather than judgment, from caregivers, educators, and mental health professionals who work with young people. Recognising defence mechanisms not as dysfunctions but as adaptive tools for maintaining psychic equilibrium opens new avenues for developmental support and therapeutic intervention.
This essay argues that Anna Freud’s theory of ego defences provides critical insight into adolescent behaviour. By analysing specific mechanisms—repression, regression, projection, and reaction formation—this paper demonstrates how these unconscious strategies help adolescents navigate identity development, emotional volatility, and interpersonal relationships. It also explores how these defences function adaptively during adolescence and when they may signal deeper psychological conflict. Ultimately, the essay seeks to show how Anna Freud’s work remains highly relevant in contemporary understandings of adolescent mental health and development.
1. Anna Freud’s Theory of Ego Defenses: An Overview
Anna Freud’s contribution to psychoanalytic theory marked a significant evolution in understanding human psychological development. While her father Sigmund Freud introduced the tripartite model of the mind—id, ego, and superego—Anna Freud focused extensively on the ego’s role, particularly in children and adolescents. Her groundbreaking work, The Ego and the Mechanisms of Defence (1936), shifted the psychoanalytic focus from instinctual drives to the ego’s function in defending the self from anxiety and internal conflict. By doing so, she not only advanced psychoanalytic theory but also laid the foundation for what later became known as ego psychology.
Defence mechanisms, as described by Anna Freud, are unconscious strategies that the ego employs to manage anxiety, internal conflicts, and social stressors. These defences are neither inherently pathological nor signs of weakness; rather, they are normal psychological responses that serve adaptive purposes. According to her, children and adolescents frequently rely on such mechanisms because their ego structures are still developing and are thus more vulnerable to emotional disturbance. The defensive function of the ego, then, is to protect psychic integrity during periods of stress, change, or conflict.
Among the mechanisms Anna Freud identified are repression, regression, projection, denial, displacement, reaction formation, and sublimation. Each of these strategies serves a different function, but all aim to reduce psychological tension and prevent the individual from being overwhelmed by emotional content. For example, repression involves keeping disturbing thoughts or desires out of conscious awareness, while projection entails attributing one’s own unacceptable impulses to others. Reaction formation converts an unacceptable impulse into its opposite—for instance, showing exaggerated friendliness toward someone one unconsciously dislikes.
In adolescence, these mechanisms become particularly prominent due to the resurgence of earlier psychosexual conflicts and the emergence of new developmental challenges. Adolescents are navigating complex tasks: establishing identity, developing autonomy, forming intimate relationships, and coming to terms with emerging sexuality. The ego, under pressure from both the internal world of instinctual drives and the external demands of society, must find ways to maintain equilibrium. Defence mechanisms provide the tools to do this—sometimes successfully, sometimes with psychological costs.
Anna Freud also introduced the idea that the form and function of defences change with age and experience. While a certain degree of denial or regression might be developmentally appropriate in early childhood, over-reliance on such mechanisms in adolescence or adulthood could hinder emotional growth. Therefore, understanding the developmental context in which a defence arises is essential to evaluating its adaptiveness.
Moreover, Anna Freud’s clinical approach involved observing children directly, often in institutional or therapeutic settings. This allowed her to link theoretical constructs with real-world behaviour, a methodology that strengthened the empirical validity of her ideas. Her clinical observations confirmed that defence mechanisms are not static; they evolve in complexity and subtlety as the ego matures.
Anna Freud’s work also holds enduring relevance in contemporary psychology and psychotherapy. Her insights into the ego’s defences have been integrated into cognitive-behavioural, psychodynamic, and developmental frameworks. Today, defence mechanisms are studied not just in clinical populations but also in everyday contexts, including education, parenting, and adolescent mental health interventions. Her theoretical clarity and developmental sensitivity offer a compassionate lens through which to interpret young people’s struggles—not as deviance or pathology, but as adaptive attempts to maintain psychological integrity amid change.
In sum, Anna Freud’s theory of ego defences offers a robust framework for understanding how adolescents cope with the emotional upheaval of development. Her emphasis on the ego’s active, protective role enables a nuanced appreciation of behaviours that might otherwise be misunderstood. By grounding defence mechanisms in developmental context, Anna Freud helped reframe adolescent behaviour as a meaningful and often constructive response to inner and outer challenges. This foundational understanding paves the way for more targeted and empathetic therapeutic, educational, and caregiving practices.
