Depersonalization-Derealization Disorder Test

What is Depersonalization/Derealization Disorder?

Most of the time, you feel connected to your body, your thoughts, and the world around you. But for some people, that connection breaks down. You might feel like you're watching your life from the outside, or that the world around you looks strangely unreal — like a dream you can't wake up from. This is depersonalization-derealization disorder (DDD).

People with DDD feel detached from themselves, their bodies, and the world around them — like watching a movie about their own life rather than living it.

The most common symptoms are:

  • Feeling that the self, emotions, or body are distant or unreal.
  • Feeling like an outside observer of one's thoughts or body.
  • Feeling that the world is not the same as it once was, or that the world seems dreamy, hazy, or artificial.
  • Feeling that memories lack emotion, seem dull, and distant.

What causes DDD?

The exact causes of DDD are not fully understood, but common contributing factors include:

  • Traumatic events: This disorder can be triggered by severe stress, such as emotional trauma, accidents, abuse, or loss of a loved one. The brain then uses DDD as a defense mechanism to cope with intense emotional pain.
  • Anxiety and depression: These conditions often worsen existing DDD symptoms, but can sometimes trigger DDD as a response to a prolonged depressive state.
  • Medications: Some strong drugs, such as those used as antidepressants, can cause feelings of depersonalization or derealization.
  • Specific medical conditions: Medical conditions such as migraines, seizures, and even some infections can lead to DDD.

Take the Depersonalization-Derealization Disorder Test

This test consists of 20 questions based on DSM-5 criteria. You will receive scores on the Depersonalization and Derealization scales, as well as an overall score. It is a screening tool only — not a diagnostic instrument. If you are experiencing these symptoms, please consult a mental health professional.
