Aims and methodMental Health Recovery Star is a multifaceted 10-item outcomes measure and key-working tool that has been widely adopted by service providers in the UK. We aimed to explore its factorial validity, internal consistency and responsiveness. Recovery Star readings were conducted twice with 203 working-age adults with moderate to severe mental health problems attending a range of mental health services, and a third time with 113 of these individuals.ResultsMental Health Recovery Star had high internal consistency and appeared to measure an underlying recovery-oriented construct. Results supported a valid two-factor structure which explained 48% of variance in Recovery Star ratings data. Two Recovery Star items (‘relationships’ and ‘addictive behaviour’) did not load onto either factor. There was good statistically significant item responsiveness, and no obvious item redundancy. Data for a small number of variables were not normally distributed and the implications of this are discussed.Clinical implicationsRecovery Star has been received enthusiastically by both mental health service providers and service users. This study provides further evidence for its adoption in recovery-focused mental health services and indicates that items relating to addictive behaviour, responsibilities and work could be further developed in future.
