Quality of care is a multidimensional concept that should include the perspectives of all parties involved. There are few instruments with adequate psychometric properties for the assessment of the quality of psychiatric care in community mental health. Quality in Psychiatric Care-Outpatient Staff (QPC-OPS) instrument has adequate psychometric properties to evaluate the quality of psychiatric care from the perspective of professionals. The aim of this study was to validate the Spanish version of the QPC-OPS instrument. The instrument was translated and back-translated, and then was administered to 260 professionals from distinct community mental health services. To assess test-retest reliability, it was re-administered after 7-14 days (n = 157). Confirmatory factor analysis revealed an 8-factor-structure identical to the original version, showing the good fit of the model. The internal consistency coefficient (Cronbach's alpha) was 0.885. The intraclass correlation coefficient was 0.847 (95% IC 0.790-0.888), which was higher than 0.70 in all factors bar one. The NT394 General Satisfaction Scale was used for analysis of convergent validity showing a rho correlation of 0.31 (p < 0.0001). Results show that the Spanish version of the QPC-OPS instrument is valid and reliable for the assessment of the quality of psychiatric care in the community setting.
