A lack of meaningful activities for people with mental ill health admitted to psychiatric inpatient care has been related to feelings of boredom and 'doing nothing' and is not in line with recovery-oriented care. Staff in psychiatric inpatient care report having limited time, ambiguous responsibilities, and insufficient support that counteracts their ideals of good nursing care and puts them at risk for high levels of stress and stress of conscience. Research highlights a need for interactions between patients and staff, but few nursing interventions with such a focus are described in the literature. This qualitative study aimed to illuminate staff experiences of introducing and participating in the nursing intervention Time Together, via qualitative content analysis of 17 individual semi-structured interviews with nursing staff in psychiatric inpatient care. The results show that these staff members experienced Time Together as an arena for mental health nursing. They prepared for the introduction of the intervention by laying a framework for success. Although the actual implementation led to them feeling burdened, they found that Time Together fostered relationships between patients and staff. For successful implementation, mental health nurses need to advocate the intervention. As Time Together constitutes an arena for mental health nursing, play and conversations based on reciprocity and equality can contribute to patients' recovery.
