6 Evidence-Based Therapies for Personality Disorders
Why Psychotherapy is Essential for Personality Disorders
Personality disorders are long-standing patterns of thinking, emotion, and behaviour that affect relationships, identity, and emotional regulation. In counselling work with clients across Alberta, many people seek therapy after noticing relationship patterns, emotional reactions, or identity struggles that feel difficult to change on their own. Psychotherapy is the primary treatment approach for most personality disorders because it addresses the underlying patterns that maintain these difficulties.

Personality disorders are deeply rooted in how we relate to ourselves and others. They don't just affect mood; they can strongly influence how a person interprets relationships, emotions, and social situations. So, medication alone often falls short. That’s why psychotherapy is the cornerstone of meaningful treatment. It helps people understand and gradually change emotional patterns, foster secure relationships, and restore a coherent sense of self.
Therapy doesn’t just aim to reduce distress; it supports people in understanding and adjusting long-standing emotional patterns. The best therapies are compassionate, evidence-based, and adaptive to the individual. The sections below explain six therapy approaches commonly used to support personality-related difficulties, along with what to expect when starting treatment.

Acceptance and Commitment Therapy (ACT) for Personality Disorders: Learning to Respond Instead of React
Acceptance and Commitment Therapy helps people change their relationship with difficult thoughts and emotions rather than trying to eliminate them. Many individuals with personality disorders experience powerful internal reactions such as shame, fear of rejection, or self-criticism. These thoughts can feel overwhelming and often drive impulsive behaviours or relationship conflicts.
ACT teaches people how to step back from those thoughts and notice them without immediately acting on them.
Instead of getting pulled into patterns like “I’m worthless” or “Everyone will eventually abandon me,” individuals learn to recognize these thoughts as mental events rather than absolute truths. ACT focuses on building psychological flexibility, which is the ability to stay present with difficult experiences while still choosing actions that align with personal values.
ACT Processes That Support Personality Patterns
ACT is built around several core processes that help people respond differently to internal experiences.
Cognitive Defusion – Learning to observe thoughts rather than automatically believing them.
Acceptance – Allowing uncomfortable emotions to exist without avoiding them.
Values Clarification – Identifying what truly matters in life.
Committed Action – Taking steps toward meaningful goals even when emotions are difficult.
Why ACT Helps with Personality-Related Patterns
Many personality disorders involve rigid thinking patterns and strong emotional reactions that shape behaviour. ACT helps loosen those patterns by creating space between the thought and the action.
Over time, individuals often develop a greater ability to tolerate difficult emotions without becoming controlled by them. Instead of reacting automatically to fear, anger, or shame, they learn to respond in ways that reflect their values and long-term goals.
Cognitive Behavioural Therapy (CBT) for Personality Disorders: How It Changes Thought Patterns
Cognitive Behavioural Therapy is one of the most widely used and studied forms of therapy. It’s built on a simple yet profound idea: how we think affects how we feel and act. For someone with a personality disorder, thoughts often become tangled in fear, mistrust, or self-judgment. CBT helps untangle that knot.
By working through unhelpful beliefs like “I’m a failure” or “Everyone will eventually leave me,” clients start to see the world differently and show up differently in it.
CBT Techniques That Work for Personality Disorders
Thought Records – Catching and evaluating negative thoughts.
Behavioural Experiments – Testing assumptions in real life.
Cognitive Restructuring – Reframing inner narratives.
Problem-Solving Skills – Finding concrete steps forward.
Why CBT Creates Long-Term Change for Personality Disorders
CBT is usually short- to mid-term (anywhere from 10 to 25 sessions), but the impact can be long-lasting because it teaches people to become their own therapist.
It doesn’t rely on someone else telling you how to think. It empowers you to observe, question, and choose. That’s especially powerful for people with personality disorders who often feel like their thoughts and emotions control them, not the other way around.
CBT creates space between reaction and response. Over time, it reduces the shame that drives withdrawal, the anxiety that fuels overachievement, and the guilt that keeps people locked in self-doubt. And while it might not rewrite every core belief on its own, it often lays the groundwork for deeper emotional work later on.
Dialectical Behavioural Therapy (DBT) for Personality Disorders: Skills for Emotional Stability
Created by psychologist Dr. Marsha Linehan, who herself lived with borderline traits, Dialectical Behavioural Therapy was built for people who’ve been told they’re “too much,” “too sensitive,” or “impossible to help.”
At its heart, DBT teaches the art of holding two truths at once: “I am doing the best I can” and “I want to do better.” That balance, called dialectics, is where real change begins.
DBT Skills That Build Emotional Regulation and Resilience
DBT isn’t just talk therapy. It’s skills training, emotional coaching, and behaviour change rolled into one. It typically involves weekly individual therapy, group skills classes, phone coaching, and a therapist consultation team.
The four DBT skill modules are:
Mindfulness – Learning to observe thoughts and feelings without getting swept away.
→ “I’m noticing I feel abandoned, but I’m not acting on it.”Distress Tolerance – Coping during emotional crises without self-harm or destruction.
→ Using ice, breathing, or sensory techniques to get through panic without hurting yourself.Emotion Regulation – Understanding what emotions mean, how they’re triggered, and how to reduce vulnerability.
→ Building routines that support mood stability: sleep, nutrition, boundaries.Interpersonal Effectiveness – Asking for what you need without aggression or collapse.
→ Saying “I feel hurt when you don’t respond” instead of lashing out or shutting down.
Who Benefits Most from DBT Therapy for Personality Disorders
DBT was originally developed for Borderline Personality Disorder (BPD) and is one of the most widely researched and commonly recommended treatments for BPD. It’s especially effective for people who experience:
Emotional dysregulation (big emotions that feel impossible to manage)
Chronic suicidal thoughts or self-harming behaviour.
Fear of abandonment and unstable relationships.
Impulsivity (in spending, sex, anger, or eating).
Extreme shifts in mood, self-image, or values.
While designed for BPD, DBT is also helpful for traits seen in:
Narcissistic Personality Disorder (especially those with shame-driven rage).
Histrionic PD (emotionally intense and relationally volatile).
Complex PTSD with personality disorder features.
If someone feels like they’re constantly at war with their own emotions, DBT can help people develop greater emotional stability and safer ways of responding during periods of distress.
How DBT Supports Emotional Stability and Safer Relationships
What sets DBT apart is its radical validation: the idea that your emotions make sense given your past experiences but that those same emotions don’t have to run the show forever.
People who complete a full DBT program often say:
“I don’t want to die every time I feel hurt.”
“I can have emotions without destroying my relationships.”
“I’ve learned how to survive things I thought would kill me.”
Emotion-Focused Therapy (EFT) for Personality Disorders: Understanding and Processing Emotions
Emotion-Focused Therapy helps individuals better understand and work through difficult emotional experiences. Many personality-related difficulties involve intense emotional reactions that feel confusing or overwhelming.
EFT helps people slow down and explore what emotions are trying to communicate.
Instead of reacting automatically to emotions such as anger, fear, or shame, individuals learn to identify the underlying needs and experiences connected to those feelings.
Core Processes in Emotion-Focused Therapy
EFT focuses on helping individuals recognize and process emotions in a structured way.
Emotional Awareness – Identifying and naming emotional experiences.
Emotional Processing – Exploring the meaning behind emotional reactions.
Transforming Emotional Responses – Replacing maladaptive emotional patterns with healthier responses.
Relationship Awareness – Understanding how emotions influence interactions with others.
Why EFT Can Help Personality-Related Difficulties
Personality disorders often involve patterns where emotions become overwhelming or difficult to interpret. EFT helps people develop greater emotional clarity and learn how to express emotions more effectively.
As emotional awareness improves, individuals often become better able to:
communicate their needs
recognize relationship patterns
regulate emotional responses
build healthier interpersonal connections
Eye Movement Desensitization and Reprocessing (EMDR) for Personality Patterns
Eye Movement Desensitization and Reprocessing is most commonly used to treat trauma, but it can also support individuals whose personality patterns are influenced by earlier traumatic experiences or attachment disruptions.
Many personality-related difficulties are linked to painful memories that continue to influence how a person sees themselves and others.
EMDR helps the brain reprocess these experiences so they no longer trigger the same level of emotional distress.
How EMDR Works
During EMDR therapy, individuals focus on specific memories while engaging in guided bilateral stimulation such as eye movements or tapping.
This process helps the brain integrate distressing experiences in a way that reduces their emotional intensity.
How EMDR Supports Personality-Related Patterns
When unresolved experiences are processed more fully, individuals often notice improvements in:
emotional reactivity
self-perception
relationship patterns
stress tolerance
While EMDR is not a primary treatment for personality disorders themselves, it can be useful when trauma or attachment injuries contribute to long-standing emotional and relational patterns.
Internal Family Systems (IFS) for Personality Disorders: Understanding the Different Parts of the Self
Internal Family Systems therapy approaches the mind as a system made up of different emotional “parts.” These parts often develop over time to help a person cope with difficult experiences, trauma, or emotional pain.
For people with personality disorders, these internal parts may sometimes conflict with one another. One part may seek closeness and connection, while another pushes people away to avoid rejection or vulnerability.
IFS helps individuals identify these internal parts and understand the roles they play.
Rather than trying to suppress or eliminate these parts, therapy focuses on developing a stronger internal leadership often referred to as the Self, which can help guide emotions and decisions more effectively.
Key Elements of IFS Therapy
IFS therapy focuses on recognizing and understanding different internal parts of the personality.
Protective Parts – Parts that attempt to prevent emotional pain through behaviours such as anger, withdrawal, or control.
Exiled Parts – Parts that carry painful memories, shame, or unresolved emotional experiences.
Self Leadership – Developing a stable internal center that can respond with calmness, curiosity, and compassion.
How IFS Supports Personality Integration
Many personality disorders involve feelings of internal conflict or instability in identity. IFS helps people understand how these internal parts interact and why certain emotional reactions occur. As individuals develop a stronger sense of Self leadership, they often experience:
greater emotional balance
less internal conflict
improved self-understanding
more stable relationships
Starting Therapy: How to Choose and What to Expect
Choosing a therapy approach can feel overwhelming, especially when several different methods are available. For many people across Alberta, the process of choosing a therapist begins after years of noticing repeated emotional or relationship patterns that feel difficult to shift alone. If you are considering support, our mental health counselling services in Alberta can help you explore which therapeutic approach may be the best fit for your needs.
Different therapies focus on different aspects of emotional and behavioural change. Some approaches are more structured and skills-based, such as Cognitive Behavioural Therapy (CBT) or Dialectical Behavioural Therapy (DBT). Others focus more on emotional processing, identity development, or understanding internal patterns, such as Acceptance and Commitment Therapy (ACT), Emotion-Focused Therapy (EFT), Eye Movement Desensitization and Reprocessing (EMDR), or Internal Family Systems (IFS).
When considering therapy, it can be helpful to reflect on a few questions that may guide early conversations with a therapist:
Do I want to focus more on past experiences or current behaviour patterns?
Am I looking for practical tools and strategies, or deeper emotional insight?
Do I prefer a structured, skills-based approach or a more exploratory style of therapy?
What approaches or strategies have helped, or not helped, in the past?
The answers to these questions do not need to be perfect. They simply help clarify what you may want from therapy and can make it easier to begin the conversation during an initial consultation.
What to Expect in Your First Sessions
The first few sessions are like unfolding a map before a long journey. You and your therapist will talk about:
Your emotional and relational history.
Discussion of symptoms and goals.
What brings you to therapy now.
Establishing a working relationship.
It might feel awkward at first. That’s normal. Building trust takes time, especially when past betrayals run deep.
Structure, Frequency, and Format
Most sessions last about 50–60 minutes, either weekly or biweekly. Depending on the therapy type you may:
Engage in group skills training or behavioural experiments.
Focus more on individual long-term exploration.
Receive homework or journaling prompts.
Practice imagery or mindfulness exercises.
Expect homework, reflection, and occasional discomfort. Therapy is hard work. But it’s the kind of hard that pays off.
Expect Emotional Ups and Downs
Therapy is often like emotional rehab; you’re strengthening something that was once hurt or underused. Sometimes that means discomfort, resistance, or moments where you wonder if anything is changing.
That’s a sign of movement, not failure.
If you ever feel overwhelmed, bring it into session. A safe therapy space is the perfect place to unpack your feelings about therapy itself.
Do Personality Disorders Need Medication?
While therapy is the core treatment for personality disorders, medication can support the process especially when symptoms are intense or co-occurring conditions (like anxiety or depression) are present.
Types of Medication Commonly Prescribed for Personality Disorders
SSRIs (e.g., sertraline) for mood swings and anxiety
Mood stabilizers (e.g., lamotrigine) for emotional volatility
Atypical antipsychotics (e.g., quetiapine) for impulsivity or paranoia
Medication isn’t about numbing, it's about stabilizing, so therapy can work better.
Why Collaborative Treatment Is Key for Personality Disorders
Always involve both your therapist and prescriber in discussions. Together, they’ll help balance your treatment plan in a way that feels safe and empowering.
Frequently Asked Questions About Therapy for Personality Disorders
How long does therapy for personality disorders usually take?
Therapy for personality disorders tends to be a long-term process because you're working to shift deeply rooted emotional and relational patterns. Some people notice early improvements within a few months, like increased emotional awareness or stronger boundaries. Other changes, like stabilizing relationships or building a more cohesive sense of identity, may take a year or more.
Can online therapy be as effective as in-person sessions for treating personality disorders?
Yes, many therapies have adapted well to virtual formats and often include digital tools, workbooks, or online skills groups. For some people, starting online actually feels more accessible and less intimidating.
Is medication ever enough on its own for personality disorders?
Medication can reduce certain symptoms, such as anxiety, depression, or mood swings. But it typically doesn’t address the core patterns behind personality disorders. Often, the most effective approach combines medication with psychotherapy tailored to your needs.
Can therapists use more than one therapy approach for personality disorders?
Yes. Many therapists integrate different approaches. A therapist might begin by using DBT to help stabilize emotions, then gradually incorporate Schema Therapy or psychodynamic work to address deeper issues. This kind of integrated approach allows the therapy to evolve as your needs change.
How do I know if therapy is helping with a personality disorder?
Progress doesn’t always look dramatic. You might still have tough days but notice you’re handling them with more awareness or less reactivity. Maybe your relationships feel less chaotic, or you’re better able to pause before reacting. There will be signs of progress even if they seem small.
Is it normal for therapy to feel difficult at first?
Yes. Digging into emotional wounds, especially ones you’ve avoided for years, can feel uncomfortable or even overwhelming. Discomfort is often a sign that you’re starting to touch the parts of yourself that need healing. A skilled therapist will help you move at a safe, manageable pace and give you tools to stay grounded.
Conclusion: Moving Forward with Evidence-Based Support
Personality disorders can feel overwhelming, but they are not a life sentence. These patterns often formed as ways to cope with pain and with the right support, they can be understood, worked through, and gradually reshaped. Therapy offers more than symptom relief; it helps rebuild trust, emotional safety, and a clearer sense of self. With structured therapy and consistent support, many individuals learn to manage emotional patterns, improve relationships, and develop greater stability in daily life.
