Initiation and Maintenance of Weight Loss after Laparoscopic Adjustable Gastric Banding. The role of Outcome Expectation and Satisfaction with the Psychosocial Outcome

Abstract

Background A premise of this study was that different psychological processes would predict the initiation and maintenance of weight loss after surgery for morbid obesity. Our aim was to examine whether more favorable preoperative expectations of psychosocial outcomes predict weight loss in the first year after laparoscopic adjustable gastric banding (LAGB) and whether postoperative satisfaction with these outcomes predicts weight maintenance in the second year after the operation. Methods Six months before and 1 year after surgery, the "Obesity Psychosocial State Questionnaire" was filled out by 91 patients (77 female, 14 male, mean age 45 ± 9 years, mean preoperative body mass index 47 ± 6 kg/m 2 ). We evaluated the preoperative outcome expectations and the postoperative satisfaction for the seven domains of psychosocial and physical functioning of this questionnaire, as well as the correlations between these scores and both weight loss and weight maintenance.Results Patients showed high satisfaction with psychosocial outcomes after LAGB in all seven domains ( p < 0.001), even though the improvement was less than expected in five of the domains ( p ≤ 0.01). While weight loss 1 year after the operation was related to satisfaction with psychosocial outcomes ( p ≤ 0.05), preoperative expectations were not related to weight loss in the first year after surgery, and satisfaction with the outcomes was not related to weight maintenance in the second year after surgery. Conclusion Our study suggests that surgically induced effects of weight loss and weight maintenance are achieved independently of the patient's preoperative expectations of and postoperative satisfaction with the psychosocial outcomes.

Identity transformation and a changed lifestyle following dramatic weight loss and body-contouring surgery: An exploratory study

“…Fourthly, our study provides supportive evidence of the relevance of the items contained within the OBSQ as a quantitative measure within research in this area, adding to preliminary findings of its psychometric properties (Zijlstra et al, 2008;Van der Beek et al, 2012). .…”

“…Permission to use the questionnaire was obtained from its Dutch devisors (Zijlstra et al, 2008). The process of translation involved the six stages outlined by Acquadro et al (2008).…”

The Impact of Reconstructive Procedures Following Bariatric Surgery on Patient Well-being and Quality of Life

“…The psychometric characteristics of the OPSQ were established in a previous study [7] and, although not validated, proved to be satisfactory. The pre-operative quality of life was measured retrospective, which may have given some bias to the results.…”

“…The actual and past psycho-social states were measured by the Obesity Psycho-social State Questionnaire (OPSQ; Table 1) [7]. The questionnaire measures seven domains: 'physical functioning' (15 items), 'mental well-being' (six items) 'physical appearance' (nine items), 'social acceptance' (four items), 'self-efficacy toward eating and weight control' (three items), 'intimacy' (four items) and 'social network' (two items).…”

Conversion to Gastric Bypass in Patients with Unsuccessful Weight Loss after Gastric Banding May Depend on Mental Quality of Life

“…Weight outcome was defined as percent of excess body mass index loss (%EBL) according to standard procedures [12]. We selected patients with unsuccessful weight outcome 2 years or more after LAGB (defined as %EBL < 25%) out of a group of 113 patients who participated in a survey study which has received the necessary ethical approval [13]. We used the last weight observation after LAGB and if applicable before conversion to gastric bypass that was recorded.…”
