Mental Health Therapy Types Explained: CBT, DBT, EMDR, and More

Updated March 28, 2026 • 11 min read • By National Healthcare Connect

When people say "therapy," they often mean something different from what the next person means. Cognitive behavioral therapy, psychodynamic therapy, EMDR, DBT, somatic therapy — these are not interchangeable brand names. They are distinct approaches with different methods, theories, and evidence bases, suited to different goals and conditions. Understanding the differences helps you find the right fit faster.

Cognitive Behavioral Therapy (CBT)

CBT is the most widely researched and evidence-based form of psychotherapy. It is based on the idea that thoughts, feelings, and behaviors are interconnected — and that changing unhelpful thought patterns changes how you feel and act.

How CBT Works

CBT is structured and goal-oriented. Therapist and client work together to identify negative automatic thoughts ("cognitive distortions"), examine the evidence for and against those thoughts, and replace them with more balanced, realistic perspectives. Between sessions, clients typically complete homework — thought records, behavioral experiments, exposure exercises.

CBT is time-limited — typically 12 to 20 sessions for most conditions, which also makes it more accessible and affordable than longer-term therapies.

Best For

• Depression
• Generalized anxiety disorder (GAD)
• Social anxiety disorder
• Panic disorder
• OCD (often combined with exposure and response prevention)
• Phobias
• Eating disorders
• PTSD (Trauma-focused CBT is a specific variant)

Dialectical Behavior Therapy (DBT)

DBT was developed by Dr. Marsha Linehan, originally for borderline personality disorder, and has since been validated for a broader range of conditions characterized by emotional dysregulation. "Dialectical" refers to balancing acceptance of the current moment with motivation to change.

Four Core Skill Modules

• Mindfulness: Awareness and acceptance of the present moment without judgment — the foundation for all other skills
• Distress Tolerance: Crisis survival skills for enduring painful situations without making them worse
• Emotion Regulation: Understanding and changing intense, destabilizing emotions
• Interpersonal Effectiveness: Skills for maintaining relationships and self-respect while asking for what you need

Full DBT typically involves individual therapy plus a weekly skills training group. Adapted DBT (individual sessions using DBT skills without the group) is also widely used.

Best For

• Borderline Personality Disorder (BPD)
• Chronic suicidal ideation and self-harm behaviors
• Eating disorders (binge eating disorder, bulimia)
• Substance use disorders
• Treatment-resistant depression with emotional dysregulation features
• Adolescents with significant emotional and behavioral challenges

EMDR (Eye Movement Desensitization and Reprocessing)

EMDR is a trauma-focused therapy developed by Francine Shapiro. It uses bilateral sensory stimulation (typically eye movements following a therapist's hand, but also tapping or sounds) while the client briefly focuses on a traumatic memory. The theory is that this process activates the brain's natural information processing to reduce the emotional charge of traumatic memories.

EMDR does not require detailed verbal narration of trauma — clients do not need to describe their experiences in detail to experience the processing. This makes it accessible for people who find talking about trauma too overwhelming.

Best For

• PTSD — EMDR has strong research support as a first-line treatment, comparable to trauma-focused CBT
• Single-incident trauma (accidents, assaults, disasters)
• Childhood and complex trauma
• Phobias with a traumatic origin
• Grief and complicated bereavement

EMDR is typically faster than traditional talk therapy for trauma — many clients see significant improvement in 8–12 sessions, sometimes fewer for single-incident trauma.

Psychodynamic Therapy

Psychodynamic therapy traces its roots to psychoanalysis but is more flexible and shorter-term. It focuses on understanding how unconscious patterns, unresolved past conflicts, and early relationships shape current thoughts, feelings, and behaviors. The goal is insight — understanding why you feel and behave the way you do — which is thought to produce lasting change.

How It Differs From CBT

CBT focuses on the present — changing current thoughts and behaviors. Psychodynamic therapy digs into the past to understand the roots of current patterns. CBT is typically shorter and more structured; psychodynamic therapy is often open-ended and exploratory. Both have solid evidence bases, but for different presentations.

Best For

• Depression with relationship difficulties
• Personality disorders (with long-term therapy)
• People with complex histories who want deeper understanding of themselves
• Relationship patterns that keep repeating
• Those who feel stuck despite trying CBT

Acceptance and Commitment Therapy (ACT)

ACT is a third-wave cognitive behavioral therapy that focuses on psychological flexibility — the ability to accept what cannot be changed, commit to valued actions, and build a meaningful life even in the presence of difficult thoughts and feelings. Unlike traditional CBT, ACT does not try to reduce or eliminate unpleasant thoughts; it changes your relationship to them.

Core processes include mindfulness, cognitive defusion (seeing thoughts as thoughts, not facts), values clarification, and committed action aligned with those values.

Best For

• Chronic pain and illness (learning to live fully alongside suffering)
• Anxiety when avoidance has become a major issue
• Depression
• OCD (as an alternative to ERP for some clients)
• Burnout and values alignment issues

Other Therapy Types Worth Knowing

Somatic Therapy

Focuses on the body-mind connection. Addresses how trauma and stress are held in the body — through physical sensations, tension, posture, and movement. Approaches include Somatic Experiencing (SE) and Sensorimotor Psychotherapy. Increasingly used alongside verbal therapy for trauma, chronic stress, and dissociation.

Interpersonal Therapy (IPT)

A structured, time-limited therapy focused on improving interpersonal relationships and communication patterns. Particularly well-studied for depression, postpartum depression, and eating disorders. Focuses on four problem areas: grief, role transitions, interpersonal disputes, and interpersonal deficits.

Couples and Family Therapy

Therapist works with couples or family systems rather than individuals. Approaches include Gottman Method (evidence-based couples therapy), Emotionally Focused Therapy (EFT) for couples, and family systems approaches. Important when the presenting problem is relational rather than individual.

Group Therapy

Therapeutic work conducted in a group setting — typically 6–12 people with a shared issue (depression, anxiety, grief, addiction, trauma). Offers peer support, reduced isolation, and often lower cost than individual therapy. Can be CBT-based, process-oriented, or topic-focused.

Which Type of Therapy Should You Choose?

Many therapists use integrative approaches — drawing from multiple modalities based on what each client needs. Do not be surprised if your therapist uses both CBT techniques and EMDR, or combines DBT skills with somatic awareness.

The most important step is getting started. Waiting for the perfect modality match often just means waiting. A good therapist can adjust approach as you go.
