The Comorbidity of Daydreaming Disorder (Maladaptive Daydreaming)

To determine the comorbidity profile of individuals meeting criteria for a proposed new disorder, daydreaming disorder (more commonly known as maladaptive daydreaming MD), the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and the Structured Clinical Interview for DSM-IV Dissociative Disorders were administered to 39 participants who met criteria for MD on a structured interview. We determined high rates of comorbidity: 74.4% met criteria for more than three additional disorders, and 41.1% met criteria for more than four. The most frequent comorbid disorder was attention deficit hyperactivity disorder (76.9%); 71.8% met criteria for an anxiety disorder, 66.7% for a depressive disorder, and 53.9% for an obsessive-compulsive or related disorder. Notably, 28.2% have attempted suicide. Individuals meeting criteria for MD have complex psychiatric problems spanning a range of DSM-5 disorders. This finding provides evidence that MD is different than normal daydreaming and that these individuals experience considerable distress and impairment.
