This quiz was adapted from the Dissociative Experiences Scale (DES-II) designed to measure a wide variety of types of dissociation.

Many people know this condition by its former name, multiple personality disorder. The negative portrayals of this condition in the media and lack of understanding of what it is have been the driving force behind the misconceptions about it.

Despite what many believe, dissociative identity disorder is a real condition. It involves experiencing shifts between at least two separate identities or personalities.

The Diagnostic and Statistical Manual of Mental Disorders, 5th edition, text revision (DSM-5-TR) categorizes this condition as a type of dissociative disorder.

Dissociation is not uncommon. Most people do it from time to time — for example when you zone out while driving. But when the dissociation begins to cause distress and interfere with your daily functioning, you may have a dissociative disorder.

When you live with dissociative identity disorder, during those zoning out moments, you may have trouble recalling memories (such as what you did) from that time. Other symptoms you may experience with DID include dissociative amnesia, a sense of depersonalization, and dissociative fugue states.

Not everyone experiences the same symptoms or the same intensity. There’s no known exact cause of DID, but it often develops in response to trauma.

Treatment typically involves therapy focused on exploring the source of trauma, reframing negative thoughts, and treating any coexisting conditions.

If you think you may have dissociative identity disorder, consider consulting with a mental health professional. With the right treatment and response, you can manage your symptoms.

This brief, time-saving questionnaire is designed for anyone who thinks they may be experiencing symptoms of dissociative identity disorder.

The statements below will help you determine whether you may need additional help and professional support for your symptoms.

A mental health professional can also help you figure out if your issues might be a symptom of DID and recommend treatment if needed.

This online screening is not a definitive tool. It’s not designed to diagnose DID or take the place of a professional diagnosis.

You can, however, use this test as a self-screening tool to track your moods. It might also show your doctor how your symptoms have changed from one visit to the next.

Only a trained medical professional, such as a doctor or mental health professional, can help you determine the next best steps for you.
