Psychotherapy treats a broad range of mental health conditions — depression, anxiety, trauma, OCD, eating disorders, and more. The three most common evidence-based approaches are CBT, DBT, and psychodynamic therapy. For moderate to severe conditions, combining therapy with medication often produces the best outcomes.
Psychotherapy is one of the most effective treatments in mental health — but the word itself can feel abstract. What exactly happens in a therapy session? What conditions does it treat? And when does medication make more sense?
This guide covers what psychotherapy is used for, the major types, their proven benefits, and how to figure out which approach — or combination — fits your situation.
Psychotherapy — also called talk therapy — is a structured set of techniques delivered by a trained mental health provider to help you understand and change patterns in how you think, feel, and behave. Sessions take place in a private, confidential setting, either in-person or via video.
The National Institute of Mental Health describes psychotherapy as "a variety of treatments that aim to help a person identify and change troubling emotions, thoughts, and behaviors" (NIMH). Unlike medication, it doesn't alter brain chemistry directly. Instead, it builds skills and insight that change how you process and respond to your world.
Psychotherapy treats a wide range of mental health conditions. Some of the most common include:
Depression: Cognitive Behavioral Therapy (CBT) is considered a first-line treatment for mild to moderate depression. It reduces symptoms and, unlike medication, often produces durable results that persist after therapy ends.
Anxiety disorders: CBT and exposure-based therapies are the gold standard for generalized anxiety disorder, social anxiety disorder, panic disorder, and specific phobias.
Post-Traumatic Stress Disorder (PTSD): Trauma-focused CBT and EMDR (Eye Movement Desensitization and Reprocessing) are the most evidence-backed approaches for PTSD.
OCD: Exposure and Response Prevention (ERP), a specialized form of CBT, is the most effective treatment for obsessive-compulsive disorder.
Eating disorders: CBT-E (enhanced CBT for eating disorders) is the most studied approach for bulimia nervosa and binge-eating disorder.
Bipolar disorder: While medication is typically necessary to stabilize mood episodes, psychotherapy plays a critical role in managing triggers, improving medication adherence, and building coping skills.
Borderline Personality Disorder (BPD): Dialectical Behavior Therapy (DBT) was specifically developed for BPD and remains the most evidence-based treatment for the condition.
Relationship and family issues: Couples therapy and family therapy address communication patterns, conflict resolution, and relational dynamics that individual therapy cannot target.
Grief and life transitions: Psychodynamic therapy and person-centered approaches help people process loss, major life changes, and identity shifts.
CBT is the most researched form of psychotherapy. The core premise: your thoughts influence your feelings and behaviors. CBT teaches you to identify distorted or unhelpful thought patterns ("cognitive distortions") and replace them with more accurate, balanced ones.
CBT is typically structured, time-limited (12 to 20 sessions), and goal-directed. It works well for depression, anxiety, PTSD, OCD, and chronic pain.
DBT is a modified form of CBT developed by psychologist Marsha Linehan for people with borderline personality disorder. It adds four skill modules: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness.
DBT has expanded well beyond BPD. It now treats eating disorders, chronic suicidal ideation, substance use disorder, and severe emotional dysregulation. Standard DBT includes individual therapy, group skills training, and phone coaching.
Psychodynamic therapy explores how unconscious processes and early life experiences shape current thoughts and behaviors. Unlike CBT, it's less structured and more exploratory. Sessions focus on patterns in relationships, recurring emotional themes, and unresolved conflicts.
It works well for depression, personality disorders, and long-standing relationship difficulties. Research shows psychodynamic therapy produces durable benefits — often with effects that continue to improve after treatment ends (American Psychological Association).
ACT teaches you to accept difficult thoughts and feelings rather than fight them, and to commit to actions aligned with your values. It works well for anxiety, chronic pain, and depression when avoidance is a central pattern.
EMDR uses bilateral stimulation — typically eye movements — to help the brain reprocess traumatic memories. The American Psychological Association and the World Health Organization both consider it a first-line treatment for PTSD.
Beyond symptom reduction, psychotherapy produces a range of documented benefits:
For mild to moderate anxiety or depression, psychotherapy alone often produces strong results. For moderate to severe symptoms, medication may be more appropriate as an initial intervention to stabilize functioning — making it possible to engage fully in therapy.
Key questions to ask yourself:
There is no universal right answer. A qualified provider can assess your history and recommend the appropriate starting point.
Research consistently shows that for several conditions, combination treatment outperforms either approach alone:
A common approach: start medication to stabilize acute symptoms, then begin therapy. Once therapy skills are established, many people work with their provider to taper medication if clinically appropriate.
If you're considering medication as part of your mental health treatment — either alongside therapy or as a starting point — an online psychiatric evaluation is the most accessible first step.
