Recommendations for the Development of Psychological Smartphone Applications in the Context of Bariatric Surgery: Focus Groups with Professionals and Patients.

To explore the experiences and preferences of patients and healthcare professionals regarding the development of an app to provide psychological intervention to improve emotion regulation in the context of bariatric surgery (BS). Sixteen people (6 patients who underwent BS and 10 professionals) participated in two separate focus group sessions. We performed a content analysis of transcribed focus group discussions to extract and organize categories, subcategories and areas. Both sets of stakeholders provided information about how to develop and implement an app. According to participants' comment, content should include information (i.e., nutrition, exercise) and emotional regulation skills. Patients and professionals mentioned that the app should include visual information, continuous emotional assessments and peer contact. It was also mentioned that the app should be used before and after BS and its contents should be developed by a multidisciplinary team (i.e., collaboration of endocrinologist, nutritionists and psychologists). Participants in both focus groups considered technology to be useful in the context of BS, especially as part of blended interventions (combining face-to-face and online sessions). Patients and professionals seem to be receptive towards the use of technology in a BS context. Specific recommendations are identified for designing and implementing app solutions for BS. More efforts should be made in the future to develop and implement evidence-based apps according to patients and professionals' needs.
