A meta-analysis covering 30 years of research has identified high rates of comorbid personality disorders across a number of anxiety disorder (AD) subtypes.
Of interest, the research findings published in the Journal of Affective Disorders found that a substantial proportion of patients with AD also presented with an avoidant personality disorder.
Oddgeir Friborg (University of Tromsø, Norway) and co-authors say this finding should be addressed in the routine clinical assessment and treatment of AD patients.
They note that large heterogeneity in post-traumatic stress disorder (PTSD) comorbidity observed in the study supports several of the proposed changes in the forthcoming DSM-V, notably moving PTSD from AD to a new cluster called “Trauma and Stressor-Related Disorders.”
The researchers identified 125 research papers published during 1980 to 2010 on patients with panic disorders, social phobia, generalized anxiety, obsessive-compulsive disorder (OCD), and PTSD, which revealed a high rate of comorbid personality disorders across all ADs (ranging from 35% for PTSD to 52% for OCD).
The comorbidity rate for patients with cluster C personality disorders (avoidant, dependent, and compulsive types) was significantly higher than for cluster B (dramatic, borderline, and antisocial types) and cluster A (schizoid, schizotypal, and paranoid types) types, at 39% versus 19% and 13%.
