Prediction of functional remission in first-episode psychosis: 12-month follow-up of the randomized-controlled trial on extended early intervention in Hong Kong

This is the first RCT providing supportive evidence to an extension of EI service beyond 2-year treatment duration on further enhancing the likelihood of FR attainment in FEP. Our findings that only approximately 20% of patients achieved FR indicate an unmet therapeutic need for promoting sustained adequate functional improvement in the early stage of psychotic illness.
