Abstract:Currently post-bariatric patients are not always able to sustain the needed behaviour change and consequently gain weight. This study had the goal to develop a tool which measures postoperative predictive behavioural parameters of weight regain of bariatric patients, to give the post-bariatric professionals insight in patients’ behavioural patterns. First, postoperative predictive behavioural parameters of weight regain were obtained via interviews. Second, the ESM [Experience Sampling Method] procedure and questions were created, via literature studies and expert meetings. Third, the tool was evaluated by measuring short-term adherence, usability, and patient satisfaction. The most important parameters were: regularity of food intake, protein intake, social support, and mood. The ESM procedure was: a smartphone app, notifications two times a day for one or two questions, two weeks, and a twenty-minutes answering slot. On average the response time was 4 minutes and 29 seconds and 66.8% of the questions were answered. Patients were satisfied with the usability. However, patients valued the app mostly negative. After the pilot it became clear that the majority of included patients did not appreciate the prototype. It is recommended to improve the app by making it more appealing for patients in terms of direct feedback and more questions.
