L’EMDR dans l’évolution de la prise en charge du TSPT : psychothérapie de la dissociation par les Stimulations Bilatérales Alternées Auditives

Abstract : Scientific background: The alternate bilateral stimulations (ABS) are techniques relating to the visual, tactile or aural modalities used in the psychotherapy EMDR "Eyes Movement Desensitization And reprocessing". Insulating research the SBA often focus on visual modality and relate its effect on subjective disturbance from the decline in observed vegetative activity. However, some PTSD do not exhibit marked vegetative activity, this correlatively with the presence of dissociation (Choi et al., 2017; Sack, Cillien, & Hopper, 2012; Briere, Weathers, & Runtz, 2005) Also, few studies are devoted to auditory ABS except to indicate their lesser effect compared to other modalities (Van Den Hout et al, 2012). On the other hand, the link between the auditory ABS and the dissociation has never been the subject of publication.Problem: What is the effect of auditory ABS on the intensity of event-related dissociation and disturbance signs?Method : After defining dissociation as a process of perception of subjective experience that escapes consciousness, we use an experimental method including 40 voluntary participants to offer an argument in favor of the interest of the auditory ABS in the treatment of dissociation. The study includes 40 healthy participants with stable vegetative activity during the recall of a disturbing memory. The subjects are randomly distributed for the treatment phase during which they recall the event simultaneously to auditory SBA (n = 20) or without hearing SBA (n = 20). The intensity of the signs of dissociation and disturbance is measured in pre-treatment and post-treatment from the average scores in the questionnaire RSDI "Response to script Driven imaging" (Hopper and LA, 2007). Results : For dissociation, there is a significant interaction between the variables group and Moment, F (1, 38) = 5.25, p =. 03. With SBA auditory, there is a difference in pre-and post-treatment scores of significant V = 134, n = 20, p =. 03; In the sense of a decrease. For subjective disturbance, there is no significant interaction between the variables and the difference in scores is not significant.DISCUSSION : The auditory technique reduces the intensity of the dissociation signs. This does not necessarily generate a disturbing subjective experience. These preliminary results open a field of research on dissociative psychopathology and of auditory ABS. Based on the work of Stanislas Dehaene on the "Global Neural work space" and consciousness, we propose a new theoretical model of ABS action by integrating its effects on dissociation. Methodological recommendations are envisaged.
