ANXIETY, DEPRESSION AND SELF-CONCEPT  AMONG MORBID OBESE PATIENTS BEFORE AND AFTER BARIATRIC SURGERY Background:  There is conflicting evidence about the emotional impact of  bariatric surgery among obese individuals. Aim: To evaluate anxiety, depression and self-concept, before and after bariatric surgery among patients with morbid obesity. Material and methods: Fifteen  males and 5 females aged 28 to 61 years with a mean body mass index of 42.6 ± 5 kg/m2, were studied.  Grid Technique (TR), Personal Self Evaluation Questionnaire (OQ-45.2) and Anxiety Sate -Trait Inventory (STAI) were applied before and six months after bariatric surgery. Results:  After surgery, the scores of self-esteem, well-being, flexibility, attraction, self-acceptance, confidence and guilt improved significantly. STAI and OQ-45.2 anxiety and depressive symptoms assessment were in the normal range before and after surgery. However, after surgery, there was a significant decrease in these sub scales in the OQ-45.2. No significant changes in anxiety measured using the STAI, were observed after surgery. Conclusions: Six months after bariatric surgery, positive changes were found in self-concept, and overall well-being.
