The aim of this study is to increase evidence-based interventions by investigating the feasibility of an intervention using an interactive digital calendar with mobile phone reminders (RemindMe) as support in everyday life. Qualitative and quantitative data were collected from participating patients (n = 8) and occupational therapists (n = 7) from three rehabilitation clinics in Sweden. The intervention consisted of delivering the interactive digital calendar RemindMe, receiving an individualized introduction, a written manual, and individual weekly conversations for two months with follow-up assessments after two and four months. Feasibility areas of acceptability, demand, implementation, practicality, and integration were examined. Patients expressed their interest and intention to use RemindMe and reported a need for reminders and individualized support. By using reminders in activities in everyday life their autonomy was supported. The study also demonstrated the importance of confirming reminders and the possible role of habit-forming. Occupational therapists perceived the intervention to be useful at the rehabilitation clinics and the weekly support conversations enabled successful implementation. This study confirmed the importance of basing and tailoring the intervention to patients' needs and thus being person-centered.
