EQ-5D as a measure of programme outcome: Results from the Singapore early psychosis intervention programme

The current study aimed to establish the Health-Related Quality of Life (HRQoL) among participants with First Episode Psychosis (FEP) in Singapore, to elucidate the sociodemographic and clinical correlates of HRQoL, and ascertain the change after 1-year of treatment. Two hundred and forty one patients accepted into an Early Psychosis Intervention Programme (EPIP) from April 2009 to June 2011 and who had completed baseline EuroQol-5D (EQ-5D) assessments were included in this analysis. The mean (S.D.) EQ-5D index at baseline was 0.788 (0.258). One hundred thirty five (56.0%) patients who completed the EQ-5D assessment at the 12-month follow-up had a significantly higher EQ-5D index as compared to baseline. EQ-5D index was significantly higher among those patients who met criteria for remission at the 12-month interval than those who were not in remission. Our results suggest that the EQ-5D is responsive to improvement as it corresponded well to objective ratings of remission in our patients with FEP. (C) 2013 Elsevier Ireland Ltd. All rights reserved.
