Development and validation of the German translation of the views on inpatient care (VOICE-DE) outcome measure to assess service users' perceptions of inpatient psychiatric care.

Background: Service user satisfaction in inpatient psychiatric care is often measured with instruments that have been designed by professionals, without involving the perspective of service users. Views on Inpatient Care (VOICE), developed in England, is among the first service-user-generated outcome measures which included service users' perspectives in the process.

Aims: In this study, we aimed to validate a German version of VOICE.
