Indonesian adaptation of the Quality in Psychiatric Care-Inpatient (QPC-IP) instrument: Psychometric properties and factor structure.

Aim: The aim of the present study was to adapt and evaluate the psychometric properties and factor structure of the Indonesian version of the Quality in Psychiatric Care - Inpatient (QPC-IP) instrument.

Methods: The QPC-IP is based on a definition of quality of care from the patient's perspective; it consists of 30 items covering six factors. A sample of 150 inpatients at general psychiatric wards in Indonesia completed the QPC-IP questionnaire.

Results: Confirmatory factor analysis revealed that the factor structure of the Indonesian version was equivalent to that of the original Swedish QPC-IP, with the exception of the secluded environment factor. The results thus demonstrate that the concept of quality of care expressed in the QPC-IP is to a large extent equivalent among inpatients in fundamentally different health care systems and cultural contexts. Internal consistency for the full QPC-IP was adequate, but poor for the separate factors.

Conclusion: The Indonesian QPC-IP is a useful instrument for evaluating psychiatric inpatient care, and thus contributes to health care improvement in the field of psychiatry.
