Brief summary
The aims of the study are to perform psychological intervention using EMDR Therapy (Eye Movement Desensitization and Reprocessing Therapy) in the preoperative period, evaluate the personality of each patient through the PFB test (Personality Factor Battery Test) at different times, compare the results obtained in the PFB test at different times of application and verify the existence of changes in the five major Personality Factors: Neuroticism, Extroversion, Socialization, Realization and Openness.
Detailed description
Obesity is a multi-factorial disease requiring a multi-professional approach. Psychological causes also contribute to the development and maintenance of obesity. Traumatic experiences may be a risk factor for it as well. Emotional issues of obese patient often interfere with the results of bariatric surgery, where a large number of bariatric patients regain the weight or change symptoms. The aim of the Effects of EMDR therapy with Severe Obesity Bariatric Surgery Patients randomized controlled trial is to determine the effects of 11 sessions of EMDR therapy, prior to surgery as compared to a control group. The Big Five personality factors will be used to evaluate the results. Both groups of patients will complete the Factorial Personality Battery, before the surgery, and 6 months and 12 months following bariatric surgery. The initial hypothesis is that EMDR therapy will provide sufficient changes after surgery in the personality dynamics of obese patients, which will in turn favor emotional balance and weight maintenance as compared to the control group.
Interventions
BEHAVIORALPersonality Factor Battery Test (PFB Test)
Psychological instrument built for personality evaluation from the model of the Five Great Factors (FGF), that includes the following dimensions: Neuroticism, Extroversion, Socialization, Effort / Commitment), focusing on the component of the aspects of Neuroticism.
BEHAVIORALEye Movement Desensitization and Reprocessing Therapy (EMDR)
It is a psychotherapeutic approach effective on treatment for trauma and post-traumatic stress disorder. It is an intervention that allows the desensitization of negative emotions from traumatic experiences.This therapy modifies memories that have been processed non-adaptively and become painful and dysfunctional memories. During the procedure, the patient is encouraged to move the eyes from side to side, associating these movements with a target situation, previously defined at the beginning of the session. The ocular movements can be replaced by tactile or sonorous stimuli. The series of stimuli must continue until the memory of the traumatic event can be reprocessed adaptively, that is, without the emotional, negative or painful process associated with that memory.
