Charting Progress in the Science of Technical Assistance for Implementation of Evidence-Based Interventions.

Technical assistance (TA) has long been a strategy utilized to support implementation of a range of different evidence-based interventions within clinical, community and other service settings. Great progress has come in extending the evidence base to support TA's use across multiple contexts, the result of more extensive categorizing of implementation strategies to support systematic studies of their effectiveness in facilitating successful implementation. This commentary builds on that progress to suggest several opportunities for future investigation and collaborative activity among researchers, practitioners, policymakers and other key decision-makers in hopes of continuing to build the success highlighted in this special issue and elsewhere. Authors call for increased attention to operationalization and tailoring of TA, considering how TA services can be sustained over time and how to consider externally-provided TA versus that housed within an organization. In addition, the commentary suggests a few key areas for capacity-building that can increase the quality, reach, and impact of TA for the future.
