What Therapists Actually Do — A Guide to Types of Therapy

You've decided you want to try therapy — or maybe someone you trust has suggested it. Either way, you're facing a bewildering landscape. There are dozens of therapy modalities, each with its own philosophy, techniques, and evidence base. Some therapists offer CBT; others specialize in EMDR, IFS, psychodynamic therapy, or ACT. What do any of these acronyms actually mean? How do you know which one is right for you? And what actually happens when you sit down (or log on) for a session?

This guide demystifies the most common and evidence-based therapy approaches, explains what each is best suited for, and helps you navigate the practical realities of finding and evaluating a therapist.

The Major Therapy Modalities Explained

Cognitive Behavioral Therapy (CBT)

CBT is the most widely researched and broadly applied form of psychotherapy. It's based on the principle that thoughts, feelings, and behaviors are interconnected — that distorted or unhelpful thinking patterns contribute to emotional distress and problematic behaviors. CBT helps you identify these cognitive distortions (catastrophizing, black-and-white thinking, mind-reading, overgeneralizing), challenge them against evidence, and replace them with more balanced, accurate thoughts. It also incorporates behavioral techniques — gradually exposing you to avoided situations, building new behavioral habits, and using behavioral experiments to test beliefs against reality.

Best for: Depression, generalized anxiety, social anxiety, panic disorder, OCD, insomnia, phobias, and many other conditions. CBT has the broadest evidence base of any therapy modality.

What sessions look like: CBT is typically structured and time-limited (12-20 sessions). Sessions follow an agenda, involve collaboration between therapist and client, and include homework assignments between sessions. The focus is on present-day problems and practical skills rather than extensive exploration of the past.

Dialectical Behavior Therapy (DBT)

DBT was developed by psychologist Marsha Linehan originally for borderline personality disorder but is now used for a range of conditions involving emotional dysregulation. It combines cognitive-behavioral techniques with mindfulness practices drawn from Zen Buddhism. The "dialectical" in DBT refers to the balance between two seemingly opposing goals: acceptance (accepting yourself and your emotions as they are) and change (developing skills to change destructive patterns). DBT is organized around four skill modules: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness.

Best for: Borderline personality disorder, chronic suicidality, self-harm, eating disorders, substance use disorders, and any condition characterized by intense, difficult-to-manage emotional responses.

What sessions look like: Comprehensive DBT includes individual therapy sessions, weekly skills group (2-2.5 hours), phone coaching between sessions, and therapist consultation team. It's one of the most intensive outpatient treatments available.

Acceptance and Commitment Therapy (ACT)

ACT (pronounced as the word "act," not the initials) is a third-wave behavioral therapy that shifts the goal of therapy from eliminating negative thoughts and feelings to changing your relationship with them. Instead of trying to control or reduce anxiety, for example, ACT helps you accept anxiety as a natural experience, defuse from the thoughts that accompany it (seeing them as mental events rather than facts), connect with the present moment, and commit to actions aligned with your personal values — even when those actions involve discomfort.

Best for: Chronic pain, anxiety, depression, OCD, substance use, and situations where traditional CBT's emphasis on thought change feels invalidating or has been ineffective.

What sessions look like: ACT sessions often involve metaphors, experiential exercises, and mindfulness practices. The therapist helps you identify your core values and the psychological barriers (avoidance, fusion with thoughts, rigid self-concepts) that prevent you from living in alignment with those values.

Psychodynamic Therapy

Psychodynamic therapy is rooted in psychoanalytic theory but has evolved significantly from Freud's original approach. It focuses on unconscious processes — patterns, defenses, and relational dynamics that operate below conscious awareness and influence current behavior and emotional experience. The goal is insight: understanding why you do what you do, how your early experiences shaped your patterns, and how those patterns replay in current relationships (including the therapeutic relationship itself).

Best for: Complex relational difficulties, persistent patterns of self-defeating behavior, identity questions, personality disorders, and people who want to understand the "why" behind their patterns rather than just managing symptoms.

What sessions look like: Sessions are typically less structured than CBT, with more free-form exploration of thoughts, feelings, and associations. The therapeutic relationship is used as a window into the client's relational patterns. Treatment tends to be longer-term, though short-term psychodynamic therapy (16-30 sessions) has a growing evidence base.

EMDR (Eye Movement Desensitization and Reprocessing)

EMDR is a structured therapy that helps the brain reprocess traumatic memories. During EMDR, the client focuses on a traumatic memory while simultaneously engaging in bilateral stimulation — typically following the therapist's finger with their eyes as it moves back and forth. This bilateral stimulation is thought to facilitate the brain's natural information processing system, helping move the traumatic memory from raw, emotionally charged storage (amygdala) to integrated, contextualized storage (hippocampus). After successful reprocessing, the memory remains but loses its emotional charge — it becomes something that happened rather than something that's still happening.

Best for: PTSD, trauma, disturbing memories, phobias, and other conditions rooted in specific distressing experiences. EMDR has strong evidence for PTSD treatment and is recommended by the WHO and the American Psychological Association.

What sessions look like: EMDR follows an eight-phase protocol: history-taking, preparation, assessment, desensitization, installation, body scan, closure, and reevaluation. Sessions can be emotionally intense but are carefully structured to ensure the client feels safe throughout. Some people experience significant relief in as few as 3-6 sessions.

Somatic Therapy

Somatic therapy encompasses several approaches (Somatic Experiencing, Sensorimotor Psychotherapy, Hakomi) that work with the body's experience of emotion and trauma. Based on the understanding that trauma is stored in the body — not just the mind — somatic approaches help clients become aware of physical sensations, release trapped survival energy, and reconnect with their bodies in safe, regulated ways.

Best for: Trauma, PTSD, chronic stress, dissociation, and people who find talk-based therapies insufficient because their distress is primarily held in physical sensation rather than cognitive narrative.

The "best" therapy isn't the one with the most research papers — it's the one that fits your brain, your history, and your goals. A brilliant CBT therapist will be less effective than a good-enough psychodynamic therapist if CBT doesn't match what you need. Trust your experience.

Internal Family Systems (IFS)

IFS, developed by psychologist Richard Schwartz, works with the premise that the mind is made up of multiple "parts" — subpersonalities, each with their own perspectives, feelings, and goals. Some parts carry pain (exiles), some protect against that pain through controlling or achieving behavior (managers), and some react when the exiles threaten to break through with extreme behaviors (firefighters). The goal of IFS is to help the client access their "Self" — a core state of calm, curiosity, and compassion — and from that place, heal and integrate the wounded parts.

Best for: Complex trauma, inner conflict, self-criticism, perfectionism, and people who experience contradictory internal states ("Part of me wants to leave, but part of me is terrified to").

How to Choose Between Modalities

With so many options, choosing can feel overwhelming. Here are practical guidelines:

• If you have a specific diagnosis (depression, anxiety, OCD, PTSD), start with the modality that has the strongest evidence for that condition. For most anxiety and depression, that's CBT. For trauma, EMDR or PE. For emotional dysregulation, DBT.
• If you want to understand deep patterns and are willing to invest time, psychodynamic therapy offers depth that briefer approaches may not reach.
• If you've tried CBT and it felt too intellectual or didn't address your body-based symptoms, consider somatic therapy or EMDR.
• If you're struggling with inner conflict or harsh self-criticism, IFS may resonate.
• If previous approaches focused on eliminating symptoms and that felt invalidating, ACT's acceptance-based framework may be a better fit.

What to Expect in a First Session

Most first sessions (often called intake or assessment sessions) follow a similar structure regardless of modality: the therapist will ask about your current concerns, relevant history (childhood, relationships, medical, psychiatric), what you've tried before, and what you're hoping to get from therapy. You'll discuss logistics (frequency, fees, cancellation policy) and begin to establish the therapeutic relationship. You should leave the first session feeling heard, relatively comfortable, and clear about next steps — even if the specific therapeutic work hasn't begun yet.

Evaluating Therapist Fit

Research consistently shows that the therapeutic alliance — the quality of the relationship between therapist and client — is the single strongest predictor of therapy outcomes, regardless of modality. A good therapist fit means you feel:

• Safe enough to be honest, even about difficult topics
• Heard, understood, and not judged
• That the therapist is competent and genuine
• Challenged when appropriate (therapy shouldn't just be validation — it should also push you toward growth)
• That the approach makes sense for your concerns

It's normal to try two or three therapists before finding the right fit. This isn't failure — it's due diligence. Most good therapists will tell you the same thing: if it's not working after a few sessions, they'd rather help you find someone who's a better match than continue ineffectively.

Cost, Access, and Online Therapy

The largest barrier to therapy isn't willingness — it's access. Therapy costs $100-$300+ per session without insurance, and even with insurance, finding an in-network therapist with availability can be extremely difficult. Options for managing cost include: sliding scale fees (many therapists offer reduced rates based on income), community mental health centers, university training clinics (where supervised graduate students provide therapy at reduced rates), and Employee Assistance Programs (EAPs), which typically offer 3-8 free sessions.

Online therapy platforms (BetterHelp, Talkspace, and others) have expanded access significantly, particularly for people in rural areas or with mobility limitations. Research on online CBT shows outcomes comparable to in-person therapy for depression and anxiety. However, online platforms may not be suitable for severe conditions, crisis situations, or therapies that require in-person components (some forms of EMDR, somatic therapy).

Therapy is an investment — in time, money, and emotional energy. But for the conditions it treats, it is among the most effective interventions in all of medicine. If you're considering it, the evidence overwhelmingly says: it's worth trying.
