RESUMO
The current study aimed to examine predictors of reduced binge eating in patients undergoing laparoscopic adjustable gastric banding (LAGB) for severe obesity. Participants were 49 patients (13 males and 36 females) who completed measures of binge eating, behavioural intentions, planning and self-efficacy two weeks prior and three months after their operation. Reduced binge eating following surgery was predicted by behavioural intentions. Planning and volitional self-efficacy were unable to predict a significant amount of variance over and above intentions. The results highlight how the role of intentions must not be overlooked when investigating the prediction of health behaviour change and challenge the notion that post-intentional constructs that translate intentions into action are more important. Interventions aiming to increase preoperative levels of intention to follow the post-operative eating guidelines in patients presenting with binge eating might be a useful way of decreasing this behaviour in patients opting for LAGB surgery in order to achieve weight loss and physical well-being.
