Assessment of clinical depression comorbid with posttraumatic stress disorder

Abstract

Comorbidity of the posttraumatic stress disorder (PTSD) and depression is often recognized in the clinical practice. The aim of the paper was to determine the severity of depression and the group of symptoms which are the most prominent in clinical depression comorbid with PTSD. Totally 60 patients were assessed and divided into the experimental and control group using the Structured Clinical Interview for DSM-IV Axis I Disorders, Investigator Version (SCID-I, modified) (SCID for DSM-IV) and ICD-10 diagnostic criteria. The presence and the severity of the disorders were assessed by means of the following intruments: Clinician-Administrated PTSD Scale for DSM-IV (CAPS-DX), Montgomery-Asberg Depression Rating Scale (MADRS) and 17-item Hamilton Rating Scale for Depression (HAMD). The differences between groups were evaluated using Student t test and by means of the correlational analysis of the data with p < 0.05. The obtained results showed that depression which was comorbid with PTSD was of significant clinical severity with 31.20 score on HAMD and 30.43 score on MADRS in PTSD-D group. The group of the symptoms: lassitude, inability to feel, suicidal thoughts and inner tension contributed mostly to the global severity of the comorbid clinical depression on MADRS. The group of the symptoms: suicide and somatic symptoms, gastrointestinal, guilt, hypochondriasis, work and activity, anxiety psychic, agitation, and weight loss, genital symptoms and anxiety somatic contributed mostly to the global severity of comorbid clinical depression on HAMD. The average score was 16.03 and 16.97 on HAMD and MADRS, respectively in PTSD group. Depression which is comorbid with posttraumatic stress disorder represents significant clinical entity with domination of the different groups of symptoms between the groups PTSD and PTSD-D on HAMD. Identification of aforementioned severity of illness and delineated group of symptoms lead the clinician to establish the diagnosis of depression, reduce the risk of diagnostic ommition of the depression and enable the clinician to chose the optimal treatment method for the delineated disorders.
