The spanish adaptation of the quality in psychiatric care-forensic inpatient (QPC-FIP) instrument: psychometric properties

Abstract

Background/Objectives: The quality of care in forensic mental health services is a factor that significantly impacts recovery and constitutes a right of the individuals receiving treatment. However, there is a lack of instruments to assess the perceived quality of care among individuals in this setting. Quality in Psychiatric Care-Forensic Inpatient (QPC-FIP) is a Swedish instrument that measures the perception of quality care from the perspectives of patients in the forensic setting. The aim of this study was to perform a cross-cultural adaptation of the QPC-FIP instrument into Spanish and to assess its reliability and validity. Methods: For the adaptation process, a translation-backtranslation of the instrument was performed. Regarding psychometric properties, the sample consisted of 120 inpatients in the forensic setting to whom the instrument was applied. To assess temporal stability, the instrument was readministered after 10 days (n = 98). Results: The confirmatory factor analysis showed an equivalent seven-factor structure with the original version, presenting a satisfactory model fit. Regarding reliability, the Cronbach's alpha value was 0.933, and the intraclass correlation coefficient was 0.836 (95% IC: 0.742-0.896), revealing results higher than 0.70 in six of the seven factors. Conclusions: The Spanish version of the QPC-FIP instrument showed adequate validity and reliability values, indicating that is a useful tool for measuring quality in psychiatric care in the forensic context.
