Aims: To develop and validate a 10 and 20-item self-report recovery-focused quality of life outcome measure named Recovering Quality of Life (ReQoL).
Method: Qualitative methods for item development and initial testing, and quantitative methods for item reduction and scale construction were used. Data from >6500 service users were factor analysed and item response theory models employed to inform item selection. The measures were tested for reliability, validity and responsiveness.
Results: ReQoL-10 and ReQoL-20 contain positively and negatively worded items covering seven themes: activity, hope, belonging and relationships, self-perception, wellbeing, autonomy, and physical health. Both versions achieved acceptable internal consistency, test-retest reliability (>.85), known group differences, convergence with related measures, and were responsive over time (SRM>.4). They performed marginally better than SWEMWBS and markedly better than EQ-5D.
Conclusions: Both versions are appropriate for measuring service-user recovery-focused quality of life outcomes.
