Depersonalization ocd update#
Therefore, this review aims to update the previous work, adopting a more systematic approach following PRISMA guidelines. As a result, the previous review may include some studies of lower quality, potentially influencing the strength of the evidence. ( 2004) did not set strict exclusion criteria for the quality of the studies under review. In order to evaluate as many studies as possible that contained some data on the prevalence of DP/DR, Hunter et al. Prevalence rates likely vary due to inconsistent definitions of DP/DR as a symptom or as a clinically significant disorder, paired with the use of a range of diagnostic tools. According to this review, the prevalence rate of DDD was 1–2% in community samples when using interviews as the diagnostic tool, while transient symptoms of DP/DR were more prevalent in the general population with lifetime rates of 26–74%. ( 2004), which included relevant papers published between 1966 and October 2002.
A recent review focusing on the epidemiology of DP/DR both as a symptom and as a disorder was conducted by Hunter et al. There is limited literature regarding the prevalence rate of DDD. On the other hand, Depersonalization-Derealization Disorder (DDD) occurs when this symptom cluster is persistent and distressing and is paired with functional impairment, rendering it a clinical diagnosis alongside other mental disorders or as a primary condition (American Psychiatric Association, 2013). Depersonalization and derealization (DP/DR) symptoms can occur as transient experiences in otherwise healthy individuals at times of stress or physical exhaustion and have been used as terms to describe the phenomenon of “burnout” (Maslach & Jackson, 1981).
There is also a possible relationship between interpersonal abuse and DDD, which merits further research.ĭepersonalization (DP) and derealization (DR) are symptoms characterized by, respectively, feelings of unreality and detachment from one’s self and one’s surroundings (American Psychiatric Association, 2013). DDD is more prevalent amongst adolescents and young adults as well as in patients with mental disorders. The prevalence rate of DDD is around 1% in the general population, consistent with previous findings. The highest rates were found in people who experienced interpersonal abuse (25–53.8%). 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 prevalence rates ranged from 0% to 1.9% amongst the general population, 5–20% in outpatients and 17.5–41.9% in inpatients. Twenty-three papers were identified and categorized into three groups of participants: general population, mixed in/outpatient samples, and patients with specific disorders. Original articles were drawn from three electronic databases and included only studies where prevalence rates of DDD were assessed by standardized diagnostic tools. A systematic review protocol was developed before literature searching. This review aims to examine the prevalence of DDD amongst different populations.
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.
