Abstract

Given the complexity of bio-psycho-social-spiritual influences, people with mental illness should be provided with multifaceted treatment and multi-system intervention. Mental health care teams are therefore expected to achieve interdisciplinary collaboration (IDC) to ensure delivery of safe, high-quality and well coordinated health care. There is increasing evidence to suggest that IDC leads to better patient outcomes. A growing body of research has shown that IDC is more effective than standard care in terms of clinical outcomes such as improved quality of life and alleviated depressed mood in people with mental disorders-with reducing healthcare costs [1]. Despite advances in research, there is still a lack of conceptual clarity of IDC, resulting in inconsistent models of care and inconsistent findings [2]. The ambiguousconceptualization of IDC impedes the standardisation of evidence-based practice and also limits practical applicability and comparability. Thorough understanding of the meaning of IDC in the context of mental healthcare is of vital importance in guiding further studies and evidence-based practice.
