Dissociation and Therapy of Depressive and Anxiety Disorders with or Without Personality Disorders

Abstract

Objective

Goal of the study was to analyze the impact of dissociation on the treatment of the patients with anxiety/neurotic spectrum and depressive disorders, and with or without personality disorders.

Methods

The sample consisted of inpatients who met the ICD-10 criteria for the Depressive disorder, Panic disorder, GAD, Mixed anxiety-depressive disorder, Agoraphobia, Social phobia, OCD, PTSD, Adjustment disorders, dissociative/conversion disorders, Somatoform disorder or other anxiety/neurotic spectrum disorder. The participants completed Beck Depression Inventory, Beck Anxiety Inventory, subjective version of clinical global impression-severity, Sheehan Patient-Related Anxiety Scale, and Dissociative Experience Scale, at the start and the end of the therapeutic program.

Results

The total of 840 patients with anxiety or depressive spectrum disorders, who were resistant to pharmacological treatment in outpatients basis and were referred for hospitalization for the six-week complex therapeutic program, were enrolled in this study. Six hundred and six of them were statistically analyzed. The patients’ mean ratings on all measurements were significantly reduced during the treatment. The patients without comorbid personality disorder improved significantly more than patients with comorbid personality disorder in the reduction of depressive symptoms. However, there were no significant differences in change of anxiety levels and severity of the disorder between the patients with and without personality disorders. The higher degree of dissociation at the beginning of the treatment predicted minor improvement. The higher therapeutic change was connected to the greater reduction of the dissociation level.

Conclusions

Dissociation presents an important factor influencing treatment effectiveness in the treatment-resistant patients with anxiety/depression with or without personality disorders.
