SILVA, Isabel; PAIS-RIBEIRO, José  e  CARDOSO, Helena. Obesity surgery: quality of life and psychological variables before and after surgical treatment. Psicol. teor. prat. [online]. 2009, vol.11, n.2, pp. 196-210. ISSN 1516-3687.

It is urgent to understand if obesity surgery (gastrobandoplasty and gastric bypass) has repercussion in psychological domain, eating behaviour and quality of life of patients submitted to it. The objective answered to compare quality of life, anxiety and depression, social support, type of motivation and perceived competence to engage in weight loss programs, relationship with the health care team and eating behaviour before and after obesity surgery (gastrobandoplasty or gastric bypass). A convenience group of 24 women answered to a set of psychological instruments before being submitted to obesity surgery and after the surgery (gastrobandoplasty or gastric bypass). Participants answered to the questionnaires, after their informed consent, in the context of a personal interview, when they went to the hospital for consultations. Results revealed that after obesity surgery occurs an improvement on quality of life, anxiety and depression. Through out treatment process (before and after the surgery), patients revealed to have a good perception of social support, to present intrinsic motivation to enrol in weight loss treatment, to perceived themselves as competent to do the treatment, to feel the health care as supportive and they did not reported non-normative eating patterns. Data analysis reveals that there are no significant differences between the two assessment moments concerning social support, motivation and perceived competence for weight loss treatment, relationship with the health care team and concerning eating behaviour. Obesity surgery (gastrobandoplasty and gastric bypass) have important repercussion in quality of life (generic and specific) and in psychological domain, namely in what concerns to anxiety and depression symptoms. It will be important to explore more deeply the other psychological variables targeted by the present research, studying a larger group of participants.
