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

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 QPC-IP instrument for a Norwegian context and assess its psychometric properties.

METHODS

The QPC-IP 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. Confirmatory 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 QPC-IP possesses good psychometric properties, including internal consistency, content, and construct validity, as confirmed by the confirmatory factor analysis results. The confirmatory factor analysis demonstrated an adequate fit for the six-factor structure, consistent with the original Swedish instrument.

CONCLUSIONS

The QPC-IP 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 QPC-IP holds potential for use in comparative, cross-cultural studies within mental healthcare services to monitor the quality of the provided services.
