Abstract

Abstract: Aim: This study aimed to examine the psychometric performance of the Recovering Quality of Life scale 10‐item version (ReQoL‐10) using a sample from a Singapore first‐episode psychosis intervention program, to explore its clinical and sociodemographic correlates, and to discuss its utility as a patient‐reported outcome measure (PROM). Methods: Sociodemographic data, duration of untreated psychosis (DUP), and diagnosis were collected from 300 participants. Clinical data, which included baseline and current scores on the Patient Health Questionnaire 9‐item version, EuroQoL‐5 Dimension 3‐level version, Positive and Negative Syndrome Scale, and Global Assessment of Functioning scale, were extracted. The ReQoL‐10 was tested for structural validity, internal consistency, and construct validity, and a multiple linear regression determined if any of the baseline factors were statistically significant predictors of the total ReQoL‐10 scores. Results: The mean (SD) total ReQoL‐10 score of the sample was 27.8 (7.8). Confirmatory factor analysis confirmed the bifactor model structure of the ReQoL‐10. The instrument demonstrated good internal consistency and adequate construct validity. Being older was associated with higher total ReQoL‐10 scores, while being married, having a highest educational level of vocational/diploma, longer DUP, and a diagnosis of affective psychosis were associated with lower total ReQoL‐10 scores. Conclusions: This study has validated the ReQoL‐10 as suitable for routine use to measure recovery‐specific quality of life in a psychiatric setting among patients with first‐episode psychosis, and is a potential tool to initiate recovery conversations. As a PROM, it can facilitate shared decision making, in line with efforts to evaluate and improve quality of care.
