Usefulness of working with a person-centred intervention in a group: Perspectives from facilitators and persons with mental illness.

Background: When implementing new interventions into clinical practice, it is of great importance to investigate the implementation process to better understand factors promoting and impeding the implementation to stimulate engagement and sustainability of the intervention. It is essential to consider perspectives both from the health professionals delivering the intervention and those receiving the intervention to be open to their suggestions for enhancing the dissemination and implementation of the intervention. The aim of the study was to evaluate adoption, acceptability and appropriateness of a person-centred group intervention (PCGI) from the perspectives of facilitators and participants with mental illness in mental health outpatient services right after delivery.
