Adaption and Cultural Validation of the Quality in Psychiatric Care-Outpatient Staff (QPC-OPS) Instrument to a Norwegian Community Mental Health Context.

The aim was to culturally adapt and validate the Swedish Quality in Psychiatric Care-Outpatient Staff (QPC-OPS) instrument for use in a Norwegian community mental health service context. The translated and culturally adapted instrument was named Quality in Psychiatric Care-Community Outpatient Staff (QPC-COPS). Three expert panels of mental health staff (n = 9) assessed the face and content validity. The internal consistency and test-retest reliability were assessed on a sample of community mental health staff (n = 64). The QCP-COPS had adequate face and content validity, and the full instrument showed excellent internal consistency (alpha = 0.90) and test-retest reliability (ICC = 0.87:0.94). In conclusion, the QPC-COPS is a valid and reliable instrument suitable for measuring staff's perception of the quality of care they deliver in community mental health services.
