Recovering Quality of Life (ReQoL)

This chapter provides an overview of the Recovering Quality of Life (ReQoL) measures – ReQoL-10 and ReQoL-20, which were developed for use as outcome measures with individuals aged 16 and over and experiencing mental health issues. The conceptual framework of the measures is described, followed by the four development stages: generation of items, content validation, scale generation, and final item selection. The involvement in the co-production of the ReQoL measures of people with lived experience of mental health difficulties and mental health service users is discussed followed by the psychometric properties of the ReQoL in the original language and other translated versions. Cultural considerations in the linguistic validation of a selection of translated versions are also presented, highlighting some of the challenges encountered. The instructions for scoring and for interpreting scores are provided, including minimum important difference and cut-off scores to distinguish between clinical and non-clinical populations. The original ReQoL English versions and 28 translated versions are also presented.
