Abstract
Depersonalization-Derealization disorder (DDD) is a psychiatric
condition characterized by persistent feelings of detachment
from one’s self and of unreality about the outside world. This
review aims to examine the prevalence of DDD amongst different
populations. A systematic review protocol was developed
before literature searching. Original articles were drawn from
three electronic databases and included only studies where
prevalence rates of DDD were assessed by standardized diagnostic
tools. A narrative synthesis was conducted. Twenty-three
papers were identified and categorized into three groups of
participants: general population, mixed in/outpatient samples,
and patients with specific disorders. The prevalence rates ranged
from 0% to 1.9% amongst the general population, 5–20% in
outpatients and 17.5–41.9% in inpatients. In studies of patients
with specific disorders, prevalence rates varied: 1.8–5.9% (substance
abuse), 3.3–20.2% (anxiety), 3.7–20.4% (other dissociative
disorders), 16.3% (schizophrenia), 17% (borderline personality
disorder), ~50% (depression). The highest rates were found in
people who experienced interpersonal abuse (25–53.8%). The
prevalence rate of DDD is around 1% in the general population,
consistent with previous findings. DDD is more prevalent
amongst adolescents and young adults as well as in patients
with mental disorders. There is also a possible relationship
between interpersonal abuse and DDD, which merits further
research.
