Changes in Posttraumatic Stress Disorder Symptoms With Integrative Psychotherapy for Functional Neurological Symptom Disorder.

Patients with functional neurological symptom disorder (FNSD) report high rates of traumatization and have high levels of posttraumatic stress disorder (PTSD) symptoms. Psychotherapy is a mainstay of treatment for persons with FNSD. In this study, the investigators explored changes in PTSD symptoms and health-related quality of life after psychotherapy among persons with FNSD and examined factors contributing to these changes. Data were prospectively collected for patients with FNSD attending a specialist outpatient psychotherapy service in the United Kingdom (N=210) as part of an ongoing routine service evaluation. Pre- and posttherapy questionnaires included self-report measures of PTSD symptoms (Posttraumatic Stress Disorder Checklist-Civilian version), depressive symptoms (Patient Health Questionnaire-9), anxiety symptoms (General Anxiety Disorder-7 scale), somatic symptoms (Patient Health Questionnaire-15), health-related quality of life (Short-Form Health Survey-36), and social functioning (Work and Social Adjustment Scale). Independent contributions to psychotherapy-related changes in PTSD symptoms and health-related quality of life were explored through multivariate analyses. All outcome measures revealed improvements after psychotherapy (p<0.001). Psychotherapy-related changes in depression and somatic symptoms and employment status at baseline explained 51% of the variance in PTSD symptom changes. Changes in PTSD symptoms, depressive symptoms, and somatic symptoms made independent contributions to improvements in health-related quality of life (R Reductions in self-reported PTSD, depressive, anxiety, and somatic symptoms, as well as improved health-related quality of life, were observed among patients who received one or more sessions of psychotherapy. Randomized controlled trials of psychotherapy for patients with FNSD are warranted.
