Posttraumatic Stress Disorder and Chronic Idiopathic URTICARIA: the Role of Coping and Personality.

This study compared the severity of chronic idiopathic urticaria (CIU) and psychiatric symptoms between patients with different levels of posttraumatic stress disorder (PTSD) and investigated a model depicting the interrelationship between PTSD from past trauma, personality traits, coping strategies, CIU severity and psychiatric symptom severity. One hundred CIU and 60 allergy patients participated in the study, completing measures on PTSD, psychiatric symptoms, personality traits and coping strategies. The results showed that for CIU patients, 7%, 40 and 34% met the diagnostic criteria for no-PTSD, partial-PTSD and full-PTSD respectively whereas for allergy patients, 15%, 45 and 18% met the same criteria. Apart from CIU, psychiatric symptom severity differed significantly between diagnostic groups. PTSD was associated with coping strategies which were in turn associated with CIU severity and psychiatric symptom severity. PTSD was not significantly associated with personality. Emotion-focused coping mediated PTSD and CIU severity, PTSD and psychiatric symptom severity and neuroticism and CIU severity. To conclude, psychiatric symptom severity varies depending on the level of PTSD among CIU patients. Neurotic patients with a high level of PTSD from past trauma show raised CIU and psychiatric symptom severity when using emotion-focused coping strategies.
