Interest of EMDR Schizophrenic Disorders (EMDRpsychose)

Interest of EMDR (Eye Movement Desensitization and Reprocessing) Psychotherapy in the Management of Schizophrenic Disorders

The purpose of this study is to determine the interest of the use of EMDR (Eye Movement Desensitization and Reprocessing) psychotherapy in the management of psychotic disorders, in particular schizophrenic disorders.

Study Overview

• Status: Terminated
• Conditions: Schizophrenic Disorders
• Intervention / Treatment: Other: Control group; Other: EMDR group

Detailed Description

Since 2015 more and more studies conducted by researchers, especially Dutch and English, are interested in the use of EMDR (Eye Movement Desensitization and Reprocessing) for other pathologies such as bipolar disorder, unipolar depression, anxiety disorders, psychotic disorders, substance use disorders and chronic pain.

These studies show that EMDR appears to be a technique that is both effective, capable of significantly improving symptoms, and without risk for patients, while respecting the protocol and the clinical stabilization provided during the procedure.

To date, the use of EMDR for the management of psychotic patients has not been the subject of any prospective study in France and the authors' conclusions converge on the fact that it is essential to carry out more research on the subject.

For this, the investigators wish to evaluate the effect of EMDR on the management of patients with schizophrenic disorders, on the basis that this psychotherapy would improve their quality of life (improvement of all the specific scores used in psychiatry). : PANSS, DES, HAD and WEMWBS scales).

Finally, the investigators believe that it is relevant to assess the benefit of EMDR six months after hospitalization of patients, in order to measure the maintenance of this efficacy in the medium term

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Assessment of the decrease in the severity of positive or negative symptoms of schizophrenia	The decrease in the severity of positive or negative symptoms of schizophrenia is assessed using the "Positive and Negative Syndrome Scale" (PANSS) between M0 and M6.This decrease will be considered effective if it's greater than or equal to 20%.	At 6 month after Hospital discharge (M0)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Assessment of the decrease in the intensity of dissociative symptoms.	The decrease in the intensity of dissociative symptoms is assessed using the Dissociative Experience Scale (DES) between M0 and M6. The DES is a short written questionnaire. It consists of 28 items that assess the frequency of various dissociative symptoms in the patient's daily life. 0 corresponds to the answer "Never" and 100 to the answer "All the time". The total score is obtained by adding the scores of the 28 items and then dividing by 28. This gives a score between 0 and 100.	At 6 month after Hospital discharge (M0)
Assessment of the decrease in the intensity of anxiety and depressive symptoms.	The decrease in the intensity of anxiety and depressive symptoms is assessed using the Hospital Anxiety and Depression (HAD) between M0 and M6 The HAD scale is a short written questionnaire, consisting of 14 items to assess the patient's symptoms of anxiety and depression. The total anxiety score is obtained by adding the scores of items 1, 3, 5, 7, 9, 11 and 13 and the total depression score by adding the scores of the remaining items. The interpretation of the results is as follows: Score ≤ 7 = absence of symptomatology, 8 ≥ Score ≤ 10 = questionable symptomatology Score ≥ 11 = certain symptomatology.	At 6 month after Hospital discharge (M0)
Quality of life assessment	The quality of life is assessed using the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS). The Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) assesses the psychological well-being of individuals. It consists of 14 items on a likert scale of 5 (1: never, 2: rarely, 3: sometimes, 4: often, 5: all the time). In this scale, there is no threshold score, but the higher the score, the stronger the psychological well-being of the individual. An improvement in the quality of life is measured by an increase in the scale score between M0 and M6	At 6 month after Hospital discharge (M0)
