Synchronizing Watches: The Challenge of Aligning Implementation Science and Public Systems.

This special issue of Administration and Policy in Mental Health explores the complexities of the outer system context in implementation science research. In this commentary, we highlight areas of asynchrony between implementation science research and policy realities of public systems. Timing is a critical factor for many aspects of system-level implementation including when and how evidence-based practice initiatives are launched, short and inconsistent timeframes for funding and support, need for early indicators of success and demonstrating return on investment. Greater consideration for the timing that drives change in public systems will strengthen efforts to implement and sustain EBPs in community settings.
