Norwegian adaptation of the Quality in Psychiatric Care – In-Patient instrument: psychometric properties and factor structure

Abstract

Background: Validated instruments measuring the quality of mental healthcare from patients’ perspectives are scarce, and available instruments have been requested. One of the few instruments measuring the quality of care from a patient’s perspective is the Swedish Quality in Psychiatric Care–In–Patient (QPC-IP). This cross-sectional study aimed to translate and adapt the QPCIP instrument for a Norwegian context and assess its psychometric properties. Methods: The QPCIP was translated and adapted to a Norwegian context using a translation back-translation process model. A total of 169 inpatients from specialised mental health services responded to the questionnaire. The QPC-IP comprises six dimensions: Encounter (eight items), Participation (eight items), Discharge (four items), Support (four items), Secluded Environment (three items), and Secure Environment (three items), totalling 30 items. Confrmatory factor analysis was conducted to assess the instrument’s factor structure. Additionally, Cronbach’s alpha was used to establish the instrument’s internal consistency. Results: The results indicated that the Norwegian adaptation of the QPCIP possesses good psychometric properties, including internal consistency, content, and construct validity, as confrmed by the confrmatory factor analysis results. The confrmatory factor analysis demonstrated an adequate ft for the six-factor structure, consistent with the original Swedish instrument. Conclusions:The QPCIP is a user-friendly and easily implementable tool that assesses various dimensions of the quality of inpatient mental healthcare from a patient’s perspective. Moreover, the Norwegian QPCIP holds potential for use in comparative, crosscultural studies within mental healthcare services to monitor the quality of the provided services.
