 The study aims to increase the understanding of how patients with drug use disorders prefer to receive app-based treatments to inform their implementation in primary care by using user-centered design methods and qualitative research methods. The results show that participants wanted to learn about apps during visits where drug use was discussed, preferred receiving clinician support for using apps over using them without support, desired a trusting, supportive relationship with a clinician who could guide them as they used the app and wanted follow-up support via phone calls or secure messaging.
