About this trial
Dissociative symptoms and disorders are particularly prevalent in the general population and among people suffering from psychiatric disorders. To date, no treatment has proven effective for this type of problem. Exploratory studies (without control group) have been carried out. Among these studies, dissociation-focused cognitive behavioral therapy (DF-CBT) seems promising. DF-CBT is based on a solid empirical model that has received numerous scientific evidence.

Trial outcomes
Primary outcomes
1
Difference in Dissociative Experience Scale (DES)
Difference in Dissociative Experience Scale (DES) between randomization and 3 months after. The DES assesses dissociation through 28 items. The total score ranges between 0 and 100, where high scores indicate high levels of dissociation.
Time frame
Between randomization and 3 months afterSecondary outcomes
1
Hetero-administered visual analogue scale
Visual analogue scales in which the practitioner rates the intensity of the patient's dissociative symptoms on the basis of his/her clinical assessment.
Time frame
At randomization, 3 months and 6 months after2
Dissociation Questionnaire (DIS-Q)
The Dissociation Questionnaire is a 63-item questionnaire measuring dissociative-trait manifestations. Participants respond to each item using a 5-point Likert scale. Four sub-scores (loss of control, absorption, amnesia and identity confusion) are calculated.
Time frame
At randomisation, 3 months and 6 months after3
Hospital Anxiety Depression Scale (HADS)
Hospital Anxiety Depression Scale (HADS) is a 14-item self-report questionnaire. Two sub-scores (anxiety and depression) are calculating. Both scores range between 0 and 21 with 0 corresponding to the ideal score (no anxiety or depression symptoms).
Time frame

Post traumatic stress disorder checklist scale (PCL-5)
