Western countries share an interest in evaluating quality of care in the healthcare field. In spite of this, there is a lack of intercultural comparison of the perceptions of professionals. One reason for this may be the lack of standardized instruments. The objective of this study was to investigate the psychometric properties and dimensions of the Spanish version of the Quality in Psychiatric Care-Inpatients Staff (QPC-IPS) instrument.
After translation and revision of the instrument by a panel of experts, a questionnaire was obtained in Spanish that was administered to a pilot sample. A total of 163 professionals participated in the study.
After conducting pilot testing and a cognitive interview with 30 professionals, it was determined that the QPC-IPS was adequate and could be self-administered. Confirmatory factor analysis confirmed six factors that explained 60.9% of the variation. In terms of internal consistency, a Cronbach's alpha of 0.92 was obtained for the full instrument. For test re-test reliability, the intraclass correlation coefficient for the overall questionnaire was 0.91. Convergent validity was analyzed using the NTP394 satisfaction instrument, yielding a positive correlation (0.58).
The results demonstrated that the psychometric properties in terms of internal consistency, temporal stability (test-retest), content validity, and construct validity (confirmatory factor analysis) were adequate. These results confirm that the structure of the Spanish version is similar to the original Swedish version of the QPC-IP.
