Persons with serious mental illness (SMI) often have coexisting medical conditions and experience a significantly reduced life expectancy compared with the general population. Peer support is considered an effective care approach for this population, and with rapid technological advancements, digital peer support, such as the DigiPer mobile application, can be a feasible self-management tool for persons with SMI. The study aims to assess the feasibility of DigiPer for persons with SMI in the Norwegian community mental health service settings.

This feasibility study will incorporate both qualitative and quantitative methods. The study consists of three phases: (1) simulation-based training among peer support workers using qualitative individual interviews; (2) pre–post study of DigiPer among peer support workers and service users using quantitative questionnaires and (3) process evaluation for peer support workers and service users using qualitative individual interviews. Peer support workers (n=5) and service users with SMI (n=15) will be recruited to evaluate the feasibility of DigiPer.

Ethics approval was granted from the Regional Committee for Medical Research Ethics (reference no. 853041), along with an assessment of processing of personal data by the Norwegian Agency for Shared Services in Education and Research (reference no. 810990). Findings will be disseminated through peer-reviewed publications and presentations at relevant national and international scientific conferences.
