Brief Summary:
Sleeve gastrectomy, Roux-en-Y gastric bypass, laparoscopic gastric banding, and bioenteric intragastric balloon insertion are common types of bariatric surgeries. These treatment strategies have diverted outcomes in body weight loss, metabolic diseases control, surgical complications, and life quality improvement. Thus, shared decision making (SDM) is necessary to aid patients to choose an appropriate treatment that suits thier needs. Investigators have developed a decision aids (DAs) and plan to conduct a randomized controlled trial (RCT) to evaluate its impact on obese patients. The measurements include a battery of interview-based questionnaires and evaluations of decision regret and knowledge improvement. Investigators expect the DAs would benefit the intervention group in the aspects of knowledge, communication and anxiety status during and after their treatment sessions.
