Specialist support for lasting patterns that affect your life and relationships
If you’ve been told you have a personality disorder—or suspect you might—you may feel confused, stigmatised, or hopeless. The term itself can feel like a judgment, as though there’s something fundamentally wrong with who you are. But personality disorders are treatable conditions, not character flaws. They represent patterns that developed for understandable reasons and can be changed with the right support.
At Clarity Psychology, our Melbourne psychologists specialise in treating personality disorders with evidence-based approaches that address deep-seated patterns while respecting your inherent worth and dignity.
What is a Personality Disorder?
Personality refers to our characteristic patterns of thinking, feeling, relating to others, and behaving. These patterns develop over time through the interaction of temperament (what we’re born with) and experience (especially early relationships and environment).
A personality disorder is diagnosed when these patterns become rigid and inflexible, cause significant distress or impairment, differ markedly from cultural expectations, are stable over time and across situations, and can be traced back to adolescence or early adulthood.
It’s important to understand that personality disorders exist on a spectrum. Many people have some traits without meeting full criteria for a disorder. And even when criteria are met, there’s enormous variation in severity and how the disorder manifests.
Types of Personality Disorders
The current diagnostic system groups personality disorders into three clusters:
Cluster A: “Odd or Eccentric”
Paranoid Personality Disorder involves pervasive distrust and suspicion of others, interpreting their motives as malevolent.
Schizoid Personality Disorder involves detachment from social relationships and a restricted range of emotional expression.
Schizotypal Personality Disorder involves acute discomfort in close relationships, cognitive or perceptual distortions, and eccentric behaviour.
Cluster B: “Dramatic, Emotional, or Erratic”
Borderline Personality Disorder (BPD) involves instability in relationships, self-image, and emotions, along with marked impulsivity. People with BPD often experience intense fear of abandonment, chronic emptiness, and difficulty regulating emotions.
Narcissistic Personality Disorder involves grandiosity, need for admiration, and lack of empathy, often masking underlying fragility and shame.
Histrionic Personality Disorder involves excessive emotionality and attention-seeking behaviour.
Antisocial Personality Disorder involves disregard for and violation of others’ rights, often with a history of conduct problems in childhood.
Cluster C: “Anxious or Fearful”
Avoidant Personality Disorder involves social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation, leading to avoidance of social situations despite wanting connection.
Dependent Personality Disorder involves excessive need to be taken care of, leading to submissive, clinging behaviour and fears of separation.
Obsessive-Compulsive Personality Disorder (different from OCD) involves preoccupation with orderliness, perfectionism, and control at the expense of flexibility and efficiency.
Understanding How Personality Disorders Develop
Personality disorders don’t arise randomly. They typically develop through a combination of biological vulnerability (temperament, genetics) and environmental factors (especially early experiences).
Many people with personality disorders experienced childhood environments that were invalidating, neglectful, abusive, unpredictable, or otherwise failed to meet core emotional needs. The patterns that characterise personality disorders often began as adaptations—ways of coping with difficult circumstances that made sense at the time.
For example, someone who learned early that expressing needs led to rejection might develop avoidant patterns. Someone whose emotions were dismissed might develop intense emotional reactions to ensure they’re heard. Someone who experienced unpredictable caregiving might develop hypervigilance about abandonment.
Understanding this helps reduce shame. Your patterns aren’t evidence of being “broken”—they’re evidence that you survived difficult circumstances. The problem is that what once protected you now causes problems in different contexts.
Evidence-Based Treatments for Personality Disorders
Several therapies have strong evidence for treating personality disorders:
Dialectical Behaviour Therapy (DBT)
Originally developed for borderline personality disorder, DBT combines acceptance and change strategies. It teaches skills in four areas: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. DBT typically involves individual therapy, skills groups, phone coaching, and therapist consultation teams.
Schema Therapy
Schema Therapy identifies and heals the deep emotional patterns (schemas) that developed in childhood and continue causing problems. It’s particularly effective for personality disorders because it addresses the developmental origins of patterns while providing practical strategies for change.
Mentalisation-Based Treatment (MBT)
MBT focuses on improving the capacity to understand one’s own and others’ mental states—thoughts, feelings, intentions. This capacity, often impaired in personality disorders, is essential for stable relationships and emotional regulation.
Transference-Focused Psychotherapy (TFP)
TFP uses the therapy relationship itself as a vehicle for understanding and changing problematic relationship patterns.
Cognitive Behavioural Approaches
Adapted CBT approaches can address specific patterns, beliefs, and behaviours associated with personality disorders.
Treatment for Specific Personality Disorders
Borderline Personality Disorder
BPD has the most treatment research, and outcomes are encouraging. DBT has the strongest evidence base, with numerous trials showing reductions in self-harm, suicidality, and hospital admissions. Schema Therapy and MBT also have strong research support. With appropriate treatment, many people with BPD experience significant improvement—some no longer meet diagnostic criteria after treatment.
Avoidant Personality Disorder
Treatment typically combines exposure-based approaches (gradually facing avoided social situations) with work on underlying beliefs about inadequacy and rejection. Schema Therapy addresses the deep-seated feelings of defectiveness that drive avoidance.
Narcissistic Personality Disorder
Treatment focuses on developing genuine self-esteem (rather than grandiosity), building capacity for empathy, and addressing the shame and vulnerability beneath the surface. Schema Therapy and psychodynamic approaches are often used.
Other Personality Disorders
While less researched than BPD, other personality disorders can be treated with adapted versions of evidence-based approaches, targeting the specific patterns relevant to each presentation.
What to Expect in Treatment
Longer-Term Work
Because personality disorders involve long-standing patterns, treatment is typically longer than for other conditions—often one to three years, though meaningful improvement often occurs earlier.
Building the Therapeutic Relationship
The relationship with your therapist is particularly important in personality disorder treatment. For many people, it becomes a corrective emotional experience—a relationship that differs from problematic earlier relationships and provides a template for healthier connection.
Skills and Understanding
Treatment combines developing practical skills (emotional regulation, interpersonal effectiveness, distress tolerance) with deeper understanding of your patterns and their origins.
Addressing Crisis
If you experience crises (such as self-harm urges or suicidal thoughts), your therapist will help you develop safety plans and skills for managing these moments.
Gradual Change
Change happens gradually. There may be setbacks along the way—this is normal and doesn’t mean treatment isn’t working. The trajectory is what matters, not individual moments.
The Evidence for Treatment
Research on personality disorder treatment has become increasingly encouraging. Key findings include: DBT reduces self-harm and suicidal behaviour in BPD by approximately 50%, Schema Therapy shows large effect sizes for BPD and is effective across multiple personality disorders, many people with BPD no longer meet diagnostic criteria after completing evidence-based treatment, and treatment gains are generally maintained at long-term follow-up.
This evidence counters outdated beliefs that personality disorders are untreatable. With appropriate therapy, meaningful change is possible.
Living with a Personality Disorder Diagnosis
Receiving a personality disorder diagnosis can bring mixed feelings. Some people feel relief—finally having a name for their struggles. Others feel stigmatised or hopeless.
A few things worth remembering: the diagnosis describes patterns, not your entire identity. These patterns can change with treatment and effort. Many people with personality disorders lead fulfilling lives with meaningful relationships. The diagnosis can guide treatment—understanding your patterns helps target interventions effectively. You’re not alone—personality disorders are more common than many people realise.
Is Specialist Treatment Right for You?
Specialist personality disorder treatment may be helpful if you’ve been diagnosed with a personality disorder, if you recognise long-standing patterns in relationships, emotions, or self-image that cause problems, if previous therapy helped with symptoms but not underlying patterns, if you experience chronic emptiness, identity confusion, or intense fear of abandonment, if emotional reactions feel overwhelming or hard to control, or if relationships follow repetitive, problematic patterns.
