Supplementary Material for: Needs and Demands for e-Mental Health Interventions in Individuals with Overweight and Obesity: User-Centered Design Approach

Introduction: Several studies indicate an association between mental disorders and overweight or obesity. E-mental-health interventions offer an effective way to overcome barriers to health care access for individuals with overweight and obesity. The objective of this study was to examine the needs and demands for e-mental health interventions among individuals with overweight and obesity. Methods: A cross-sectional study was conducted from 2020 to 2021 in Germany. A total of 643 participants were recruited through specialized social media platforms and the Alfried-Krupp hospital in Essen, Germany. Sociodemographic and medical data were analyzed, as well as data on depressive symptoms and on the needs and demands for e-mental health interventions. Results: Contact with and recommendation by experts appear to be key aspects in the acceptance and use of e-mental health interventions. In summary, most participants preferred a 20- to 30-minute weekly session via smartphone over a four-month period. The highest preference in terms of features included practicing coping skills and being provided with information; in regard to desired topics, nutrition consultation, quality of life and adapting to new life situations were considered most important. Discussion: E-mental health interventions can be highly beneficial for individuals, especially when developed through a user-centered design approach. The results of the study indicate which content and design are preferred and, thereby, provide valuable information for consideration when developing a tailored e-mental health intervention.
