Policy development and challenges of global mental health: a systematic review of published studies of national-level mental health policies

Mental health policy developments in both HICs and MLICs present a process of diversification and enrichment.

Therefore, future efforts should not only be made on helping MLICs developing mental health policies, but also on promoting policy implementation under MLICs' local context.
