10 Science-Backed Therapy Methods for Anxiety and Depression

Anxiety and depression are common, treatable conditions. If you’re reading this, you’re probably looking for practical, evidence-based approaches that actually help. Below I’ve collected 10 well-researched therapy methods—what they are, why they work, who benefits most, how long they typically take, and realistic cost figures where applicable. I’ll also share expert quotes and simple tips so you can take the next step with confidence.

1. Cognitive Behavioral Therapy (CBT)

What it is: CBT is a structured, time-limited therapy that helps people identify and change unhelpful thoughts and behaviors. It’s the most widely studied psychotherapy for both anxiety and depression.

Why it works: CBT teaches practical skills—thought records, behavioral experiments, and activity scheduling—that reduce symptoms and prevent relapse. Numerous randomized controlled trials show moderate-to-large effects compared with no treatment.

Who it helps most: People with major depressive disorder, generalized anxiety disorder, panic disorder, social anxiety, and many related conditions.

Typical course: 12–20 weekly sessions (often 50–60 minutes each).
Evidence: Strong—multiple meta-analyses support efficacy.
Practical tip: Practice between sessions—skills are where change happens.

“CBT works because it gives patients tools they can use long after therapy ends. It’s very practical,” says Dr. Emily Carter, clinical psychologist.

Cost (typical, U.S.): $100–$250 per session; many insurers cover some or all of the cost. Online CBT programs may be cheaper ($40–$150/month).

2. Acceptance and Commitment Therapy (ACT)

What it is: ACT focuses on accepting uncomfortable thoughts and feelings while committing to actions aligned with personal values. It’s less about changing thoughts and more about changing your relationship to them.

Why it works: ACT builds psychological flexibility—people learn to act even when negative feelings are present, which reduces avoidance and improves functioning.

Typical course: 8–16 sessions, sometimes integrated into ongoing therapy.
Evidence: Growing—meta-analyses show ACT is effective for anxiety, depression, and stress, often comparable to CBT.
Practical tip: Use short mindfulness exercises and identify one value-driven action each day.

“Many clients find relief through small values-focused changes. It’s less about ‘fixing’ thoughts and more about living a meaningful life,” notes Dr. Marcus Li, clinical psychologist specializing in ACT.

Cost: Similar to CBT—$100–$250 per session; group ACT workshops may be $100–$500 per course.

3. Mindfulness-Based Cognitive Therapy (MBCT)

What it is: MBCT blends CBT principles with mindfulness training. It was developed specifically to prevent relapse in recurrent depression but also helps anxiety.

Why it works: MBCT teaches people to notice when they’re slipping into negative thinking and to step out of automatic reactions before relapse occurs.

Typical course: 8-week group program (weekly 2-hour sessions + daily home practice).
Evidence: Strong for depression relapse prevention; helpful for anxiety reduction.
Practical tip: Start with short daily mindfulness practices (10–20 minutes) and gradually increase.

“MBCT equips people with a daily practice that can transform how they relate to tough thoughts,” says Dr. Anna Ruiz, researcher in mindfulness interventions.

Cost: Group MBCT programs often range from $200–$800. Individual MBCT-based therapy aligns with standard psychotherapy rates.

4. Interpersonal Therapy (IPT)

What it is: IPT focuses on improving interpersonal relationships and role transitions that contribute to depression and anxiety symptoms. It’s structured and time-limited.

Why it works: By resolving relationship issues—grief, role disputes, role transitions—people reduce stressors that maintain depression and improve social support networks.

Typical course: 12–16 sessions.
Evidence: Strong for depression, especially in women and in contexts where relationship stressors are primary.
Practical tip: Map your key relationships and identify one actionable communication change to try weekly.

“IPT helps people understand how relationships shape mood—and then teaches specific ways to change interactions,” explains Dr. Samuel Ortiz, psychiatrist.

Cost: $100–$250 per session; some community clinics offer sliding-scale IPT options.

5. Behavioral Activation (BA)

What it is: BA is a practical, activity-focused therapy that targets the withdrawal and avoidance behaviors that sustain depression.

Why it works: Increasing engagement in rewarding and meaningful activities boosts mood and breaks cycles of avoidance. It’s straightforward—track activities, set goals, and build routine.

Typical course: 8–16 sessions; sometimes used as a quick intervention within primary care.
Evidence: Strong—BA is as effective as CBT for many people with depression.
Practical tip: Start with small, specific goals—e.g., 10 minutes of walking three times a week—and build up.

“Behavior matters. Often changing what you do changes how you feel,” says Dr. Lily Morgan, behavioral therapist.

Cost: Similar to CBT; some brief BA programs in clinics or primary care cost $50–$150 per session.

6. Exposure Therapy

What it is: Exposure therapy gradually and safely exposes people to feared situations, thoughts, or sensations to reduce avoidance and anxiety responses.

Why it works: Repeated, controlled exposure allows the brain to relearn that feared outcomes are unlikely and that anxiety decreases over time (extinction learning).

Typical course: Varies—often 8–20 sessions depending on severity and complexity.
Evidence: Gold standard for phobias, panic disorder, social anxiety, and PTSD-related anxiety.
Practical tip: Work with a trained therapist to create a graded exposure hierarchy—start small and build.

“The most common mistake is avoidance. Exposure teaches you the opposite: the body can tolerate anxiety and it will settle,” says Dr. Karen Bishop, anxiety specialist.

Cost: $120–$250 per session; intensive programs (e.g., multi-day) can run $1,500–$5,000 depending on format and location.

7. Eye Movement Desensitization and Reprocessing (EMDR)

What it is: EMDR is a structured therapy originally designed for trauma that uses bilateral stimulation (eye movements or taps) combined with memory processing to reduce distress linked to traumatic or disturbing memories.

Why it works: EMDR appears to accelerate adaptive processing of distressing memories; many people experience symptom reduction in fewer sessions than traditional talk therapy.

Typical course: 6–12 sessions for specific trauma-focused work; more if multiple issues exist.
Evidence: Strong for PTSD; growing evidence for anxiety and depression with comorbid trauma.
Practical tip: Use EMDR with trained, certified providers; it’s highly experiential.

“EMDR can be remarkably efficient for trauma-related distress, often yielding deep symptom relief in a short timeframe,” notes Dr. Rachel Nguyen, EMDR-certified clinician.

Cost: $150–$300 per session; some clinics offer package pricing for a course of EMDR treatment.

8. Medication Management (SSRIs, SNRIs and others)

What it is: Antidepressant medications—such as SSRIs (e.g., sertraline, escitalopram) and SNRIs (e.g., venlafaxine, duloxetine)—are commonly used to treat moderate-to-severe depression and many anxiety disorders.

Why it works: These medications adjust neurotransmitter systems (serotonin, norepinephrine) implicated in mood and anxiety regulation. They’re often combined with psychotherapy for best results.

How long to expect: Benefits typically begin in 2–6 weeks; full effect often by 8–12 weeks.
Evidence: Robust—large trials show efficacy for many people; response rates vary (~40–60% depending on condition and severity).
Practical tip: Monitor side effects and keep regular follow-ups with your prescriber.

“Medication doesn’t replace therapy, but it can make therapy more effective by stabilizing mood early on,” says Dr. Harish Patel, psychiatrist.

Cost (typical, U.S.): Generic SSRIs can cost $4–$50/month with insurance or discount programs; brand-name medications may be $100–$400/month. Psychiatric visits for medication management often run $150–$400 per visit depending on provider and duration.

9. Transcranial Magnetic Stimulation (TMS)

What it is: TMS is a noninvasive brain stimulation technique that uses magnetic fields to stimulate regions of the brain involved in mood regulation. It’s typically reserved for treatment-resistant depression.

Why it works: Repeated stimulation can modulate neural circuits and improve mood in patients who haven’t responded to medications or therapy.

Typical course: Daily sessions (M–F) for 4–6 weeks; each session lasts ~20–40 minutes.
Evidence: Strong for treatment-resistant depression; many patients who did not respond to meds show significant improvement.
Practical tip: Evaluate whether your insurance covers TMS—many insurers do after prior treatment failure.

“For some patients, TMS has been life-changing—especially when other options failed,” says Dr. Olivia Sandberg, neurologist specializing in neuromodulation.

Cost: $6,000–$12,000 for a full course in the U.S. Insurance coverage varies; out-of-pocket costs can be substantial but many insurers now cover TMS with prior authorization.

10. Ketamine-Assisted Therapy (and Esketamine)

What it is: Ketamine (off-label IV or IM) and esketamine (a nasal spray FDA-approved name: Spravato) are rapidly acting treatments for severe, treatment-resistant depression and some forms of suicidal ideation.

Why it works: Ketamine modulates glutamate neurotransmission and can rapidly reduce depressive symptoms—sometimes within hours or days—unlike traditional antidepressants.

Typical course: Initial induction often involves 2–6 treatments over 1–3 weeks, then maintenance sessions as needed.
Evidence: Growing—controlled trials show rapid antidepressant effects; long-term protocols are still being refined.
Practical tip: Ketamine protocols include psychological support; combining infusion with therapy often improves outcomes.

“Ketamine is not a first-line option, but for people in acute distress, it can be a critical bridge to stabilization,” says Dr. Miguel Alvarez, addiction psychiatrist and ketamine researcher.

Cost: $400–$1,200 per infusion/session for ketamine; esketamine (Spravato) often costs $600–$1,000 per treatment session after insurance, with induction phase typically more frequent. Many clinics require in-office monitoring, adding to cost.

How to Choose the Right Therapy

Picking a therapy can feel overwhelming. Here’s a simple, practical approach:

Identify the primary problem: Are symptoms mainly mood-related (depression), worry/avoidance (anxiety), or trauma-related? Certain therapies target specific mechanisms.
Consider severity and urgency: For severe or suicidal depression, urgent psychiatric evaluation and possibly medication or ketamine are priorities.
Think about access and cost: Online CBT or community mental health clinics can be more affordable. Insurance coverage varies—call your insurer to confirm.
Look for trained providers: For specialized treatments (EMDR, TMS, ketamine), ensure clinicians have certification and positive reviews.
Combine when helpful: Medication + psychotherapy often produces stronger and faster results than either alone.

Practical checklist before starting:

Ask potential providers about their training in the specific method.
Confirm session length and estimated number of sessions.
Check insurance coverage or availability of sliding-scale fees.
Discuss measurable goals and how progress will be tracked.

Real-World Examples

Example 1: Jane had recurrent depression and anxiety. She started MBCT in a group class ($350 for 8 weeks) and continued weekly CBT sessions for targeted skill work. Within 3 months she reported fewer depressive days and better sleep.

Example 2: Marcus had severe treatment-resistant depression. After multiple failed antidepressants, his psychiatrist referred him for TMS (covered by insurance after prior authorization). After a 6-week course he showed significant mood improvement and could return to part-time work.

Common Questions

How long until I feel better? Early changes can occur in weeks for therapies like CBT and medication—full benefits often take 8–12 weeks. Ketamine can produce rapid improvements within hours to days for some people; TMS usually shows gains across several weeks.

Can therapy fully cure depression or anxiety? “Cure” depends on definition. Many people experience remission (major reduction or absence of symptoms). Therapy often equips people with lifelong skills to manage and prevent relapse.

What if I can’t afford traditional therapy? Look for sliding-scale clinics, university training clinics, community mental health centers, and evidence-based digital programs. Many regions offer low-cost group therapy and nonprofit resources.

Final Thoughts

There’s no single “best” therapy for everyone—what matters is choosing an evidence-based approach that fits your needs, working with a trained provider, and sticking with the plan long enough to see change. As Dr. Emily Carter summarized: “Effective treatment is not magic—it’s matched care plus consistent practice.”

Start small: pick one clear, measurable goal (sleep 30 minutes earlier, practice 10 minutes of mindfulness daily, or call a supportive friend twice a week). Track progress for four weeks and reassess. Combining therapy with lifestyle steps (regular exercise, sleep hygiene, and social support) multiplies benefits.

If you’re in crisis or thinking about harming yourself, contact emergency services or a crisis hotline immediately (in the U.S. call 988). For non-urgent care, speak with a primary care provider or mental health professional to create a plan tailored to your needs.

Remember: help is available, and research-backed options exist for almost every situation. Small steps add up to meaningful change.
