Approche psychologique de la résilience chez les personnes en situation d’obésité sévère candidates à une chirurgie bariatrique : étude des effets d’une prise en charge multidisciplinaire avant chirurgie

Abstract : Candidates for bariatric surgery have a singular biopsychosocial trajectory: very severe or complicated obesity, frequent psychopathologies and difficult and traumatic life histories. Considering medical treatment as a failure, they see surgery as the ultimate solution. Resilience’s concept enables to come closer the psychic and social fragility of these people. The main objectives of the study are to pinpoint their psychic functioning and to identify their evolution during a healthcare pathway of preparation for bariatric surgery, using a semi-quantitative approach of psychodynamic inspiration. Two hundred subjects who are candidates for bariatric surgery (153 women and 47 men, age: 43.5 ± 11.74 years, BMI: 45.54 ± 7.19 kg/m2) were recruited at the beginning of their healthcare pathway of preparation at CHRU of Nancy. This one-year circuit is based on a cognitive-behavioral access and offers collective therapeutic education working group.Three methodologies were used at the beginning and end of this circuit in order to explore the different dimensions of resilience in severe obesity context: clinical research interviews, projective data (102 Rorschach protocols) and self-questionnaires enabling the quality of life (EQVOD and SF-36), eating disorders (ED) (DEBQ and BES), psychopathologies (HAD and MINI), coping mechanisms (Briefcope), alexithymia (TAS), and resilience (RSA) to be assessed.The resilience process is nonexistent at the beginning of the circuit. Results indicate that the subjects have a poor quality of life as well as many psychopathologies: food compulsions (62.89%, including 56.6% of Binge Eating Disorder (BED)), depressions (15%), anxieties (34, 5%) or addictions (29.5%). A significant number of difficult and traumatic life events is noted: 86% of the subjects have polytraumatic past life experiences mostly going back to childhood and adolescence periods.Paradoxical responses given by some subjects at self-questionnaires authorize them to be classified according to a behavioral profile known as "discordant" (underestimate of binge eating at BES and overvaluation of resilience at RSA) which is characterized by a deficit of mentalization identified at the clinical interview and at Rorschach.A clear improvement of all these indicators is certified at the end of this circuit. The quality of life of subjects, especially psychic, increase. The prevalence of psychopathologies, it, strongly decreases, with significant reductions in eating behavior disorders in terms of frequency (64.78%) and intensity (13.21% with sizable compulsivity), depressions (3.14%), anxiety (8.18%) and addictive behaviors (13.84%). Lastly, mentalization’s difficulties decreased, although the majority of subjects still have an absence of resilient process just before surgery. Subjects with a "consistent" profile according to the self-questionnaires, know a significant improvement in the majority of indicators, compared to "discordant" subjects
