Participants' perspectives on perceived usefulness of digital and in-person diabetes prevention programs: A qualitative study to inform decisions related to program participation.

Objective: Given the effectiveness of both in-person and digital diabetes prevention programs (DPPs), participants have an opportunity to select a delivery mode based on their needs and preferences. The objective of this study was to understand and compare participants' experiences with digital and in-person DPPs to identify factors that affected how useful participants perceived these two program delivery modes. Methods: Semi-structured interviews with participants who were enrolled in DPPs as either a digital ( Results: Findings from the interviews indicated that creating accountability for weight loss was crucial for all program participants. In the digital program, weight and food tracking played a central role in creating accountability, while in the in-person program, group interactions fostered accountability. The digital program was perceived to encourage self-monitoring, oftentimes resulting in participants' reflection on their habits. The in-person program provided a platform for group support and mutual encouragement. Conclusions: Participants perceived both programs as similarly useful. Yet program characteristics such as the ability to engage with other participants in-person or to seamlessly track weight on a daily basis appealed to different participants. It may be beneficial to align participants' preferences with programs' characteristics and strengths.
