Confused About Mental Health Professional Titles? You're Not Alone

Therapist, psychologist, psychiatrist, counselor—what's the difference, and who do you need to see? Let's clear this up.

The Different Roles Explained

Psychotherapist or Counselor (LMFT, LCSW, LPC)
Licensed mental health professionals with master's degrees who provide talk therapy. All can diagnose mental health conditions and provide treatment. I'm [Your credential], which means [what you're licensed to do].

Psychologist (PhD or PsyD)
Doctoral-level professionals who provide therapy and conduct psychological testing. They can diagnose conditions and provide specialized assessments (ADHD testing, psychological evaluations) but generally cannot prescribe medication.

Psychiatrist (MD or DO)
Medical doctors who specialize in mental health. They prescribe medication, diagnose conditions, and can provide therapy, though many focus primarily on medication management.

What Each Can Do

All three can diagnose mental health conditions, create treatment plans, and provide therapy.

Only psychologists can conduct comprehensive psychological testing and administer formal assessments.

Only psychiatrists can prescribe medication and order medical tests related to mental health.

Who Do You Need?

Start with therapy: For anxiety, depression, relationship issues, trauma, or life transitions, any licensed therapist can help. Most people start here.

Add testing if needed: If there are diagnostic questions (ADHD vs. anxiety?), a psychologist provides formal testing.

Consider medication: If therapy alone isn't enough or symptoms are severe, a psychiatrist can evaluate whether medication might help. [Whether you work with psychiatrists - e.g., "I coordinate with psychiatrists when medication might benefit my clients"].

Can You See Multiple Providers?

Absolutely. Many people work with both a therapist and psychiatrist (called collaborative care). Your therapist provides ongoing talk therapy while your psychiatrist manages medication. [Your approach to collaboration].

Finding the Right Provider

For therapy: Search Psychology Today, your insurance provider directory, or ask for referrals.
For testing: Ask your psychotherapist for psychologist referrals.
