Understanding the Struggles of Identity in Borderline Personality Disorder and the Role of Dialectical Behaviour Therapy

Borderline Personality Disorder (BPD) is a pervasive mental health condition characterized by instability in moods, self-image, behaviour, and interpersonal relationships. A core feature that often goes unnoticed amidst these dramatic outbursts and tumultuous relationships is the struggle with identity. The individual’s self-perception can oscillate wildly, causing them to feel lost within their own existence.

BPD and Identity

Identity issues are more than an existential crisis; they are ingrained into the diagnostic criteria for BPD. The DSM-5, a widely recognized manual on psychiatric diagnoses, includes “markedly or persistently unstable self-image or sense of self” as one of its nine criteria for diagnosing BPD. This struggle with identity can manifest in many ways.

It might start subtly — perhaps a frequent change in hobbies or career goals — but soon, it becomes more noticeable as these changes become more drastic and frequent. Individuals with BPD might adopt drastically different values or beliefs overnight without logical reasoning. These shifts often lead to an inconsistent life narrative which is also reflected in fluctuating ambitions, goals, friendships and even sexual orientation at times.

The individual’s perception of themselves can vary from feeling unworthy of love to believing they’re superior to others. This intense emotional suffering often leads to impulsive behaviours like risky sexual encounters, substance abuse, binge eating, or reckless driving as a means to escape from their painful reality.

Dialectical Behavior Therapy (DBT)

Dialectical Behavior Therapy (DBT), developed by psychologist Marsha Linehan in the late 1980s specifically for treating BPD patients, has shown promise in managing these issues related to identity. DBT blends cognitive-behavioural techniques with mindfulness practices derived from Buddhist meditative traditions.


The first stage of DBT involves focusing on mindfulness – being present in the moment without judgment – which allows individuals to be aware of their thoughts and feelings without becoming overwhelmed by them. Through consistent practice, individuals learn how not to latch onto every passing thought about their identity; instead, recognize them as transient experiences that do not define who they are fundamentally.

Distress Tolerance

Secondly comes distress tolerance which teaches individuals how to accept both themselves and their current situation without resorting to destructive behaviour during moments of crisis. It promotes healthy coping mechanisms such as distraction techniques or self-soothing methods rather than impulsive reactions like substance use or self-harm when faced with painful emotions.

Emotion Regulation

The third module focuses on emotion regulation, where individuals learn how to identify and label emotions accurately while reducing emotional vulnerability through various strategies like balanced eating/sleeping habits and regular physical activity, among others. Better understanding and management of emotions help mitigate the extreme fluctuations contributing to unstable self-perception.

Interpersonal Effectiveness

Lastly comes interpersonal effectiveness – teaching skills for asking what one needs assertively while maintaining respect for oneself and others, thus improving relationships overall which indirectly fosters a healthier sense of self-worth over time.

A key aspect that makes DBT effective for those struggling with identity issues is its dialectic philosophy: holding two seemingly opposing truths together. For instance, one hand accepts that you’re perfect just the way you are right now (“radical acceptance”) while simultaneously acknowledging that there’s room for positive change & growth (“change”).

This paradoxical co-existence reinforces the idea that our core remains constant regardless of external circumstances, thus helping stabilize the wavering sense of identity associated with BPD over time through consistent practice.

To conclude, it’s essential we approach those grappling with Borderline Personality Disorder empathetically understanding their internal chaos rather than dismissing them based on outward behaviors alone. Their journey towards a consolidated sense of identity isn’t easy but assuredly possible through proven therapeutic modalities like Dialectical Behavior Therapy coupled with solid support networks aiding them throughout this challenging yet transformational expedition.
