Evaluation of Online Mental Well-being Intervention for Working Adults

This study aims to evaluate the effectiveness and cost-effectiveness of the online stepped-care mental well-being system together with offline programs in comparison to care as usual. This study will provide important findings for future health economic analyses of blended stepped-care mental well-being interventions which may increase public\'s access to mental well-being services and ease the long waiting time under the current public healthcare system. It is hypothesized that participants in the intervention group show (H1) greater reduction in depressive and anxiety symptoms, (H2) better improvement of well-being, (H3) better improvement of quality of life, and (H4) lower incremental cost-effectiveness ratio (ICER), compared to care as usual.
