OBJECTIVES: The effect of short-term psychodynamic psychotherapy in patients with neurotic spectrum disorders may be related with predictive factors such as the severity of the disorder, diagnosis, self-stigma level, personality characteristics, comorbidity with depression and personality disorder, dissociation, and traumatic childhood experience. This study focuses on finding factors related to the effect of short-term psychodynamic psychotherapy in patients with neurotic spectrum disorders. METHOD: The study was conducted at the Psychotherapeutic ward of the Psychiatric Department in Regional Hospital Liberec from October 2015 to March 2019. The assessment method used at the beginning was the objective and subjective Clinical global impression (objCGI, subjCGI), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI-II), Dissociative Experience Scale (DES), Liebowitz Social Anxiety Scale (LSAS), Internalized Stigma of Mental Illness (ISMI), Temperament and Character Inventory (TCI), Parental Bonding Style (PBI), Childhood Trauma Questionnaire (CTQ). The 6-week therapeutic program combines group dynamic psychotherapy (4 times a week for 1.5 hours), pharmacotherapy and other therapeutic activities. The primary criterium of therapeutic outcome was the change in objCGI severity, and the secondary criteria were changes in subjCGI, BAI and BDI-II. RESULTS: A total of 96 hospitalized patients with neurotic spectrum disorder diagnosed according to ICD-10, confirmed with the MINI (MINI-International Neuropsychiatric Interview) were included in the study and filled out the questionnaires' battery. There was a statistically significant decrease in the anxiety and depression symptoms and an overall decrease in the disorder's severity during the treatment. At the beginning of the treatment, a higher self-stigma rate was associated with a smaller decrease in anxiety symptoms (BAI) and depression (BDI-II). However, self-stigma is not a factor associated with the change in primary outcome criteria (objCGI change). Initial assessment of objective severity of the disorder (objCGI) and personality factor Novelty Seeking predict the change in objCGI severity. CONCLUSIONS: Self-stigma predicted the change in anxiety and depressive symptom but not the change of the disorder's global severity in short-term psychodynamic psychotherapy of patients with a neurotic spectrum disorder.
