A mixed-methods validation of the 15-item English version of the Questionnaire about the Process of Recovery (QPR) in an adult mental health inpatient rehabilitation setting

Abstract

ABSTRACT Background Recovery is a key outcome within healthcare services and can be assessed using the Questionnaire about the Process of Recovery (QPR). Research indicates good psychometric properties in community samples, but no research has extended this to inpatient settings. The face validity of the QPR has not been assessed. This research aimed to explore the psychometric properties of the QPR in an adult mental health inpatient rehabilitation setting. Method 150 inpatients completed the QPR questionnaire. 10 inpatients participated in a semi-structured interview to assess face and concurrent validity. Results The results indicated a single factor solution was appropriate, explaining 51.4% of the variance. Internal consistency was excellent (α = 0.94). No floor or ceiling effects were observed. Interviews indicated good face and content validity. Discussion Overall, this research supports the use of the 15-item QPR in inpatient rehabilitation settings as all assessed psychometric properties were adequate. Some participants suggested additional aspects of their recovery that the QPR did not cover, supporting the use of the QPR alongside other symptom-specific measures.
