Thalassophobia Scale: Test Your Fear of Deep Water

Assess your anxiety levels regarding deep bodies of water.

By Mark Travers, Ph.D. | Last Updated: March 19, 2026

Thalassophobia is defined as an intense, persistent fear of the sea or large bodies of water. While many people feel a natural caution around the ocean, true thalassophobia can trigger panic attacks and avoidance behaviors that interfere with daily life. This Thalassophobia Scale is designed to help you quantify your anxiety regarding deep water, vast expanses, and the unknown depths. If you are interested in exploring other specific phobias, you might also want to take our Spider Fear Questionnaire or our Emetophobia Questionnaire to better understand your anxiety triggers.

For each statement, indicate how much you agree. For best results, answer honestly and trust your first instinct.

1. Proximity to the ocean has caused me panic attacks or severe anxiety.

3. The thought of being in deep ocean waters causes me anxiety.

5. My fear of the ocean prevents me from boating or swimming.

6. I feel uncomfortable watching films or videos set in the ocean.
