Handbook of Intervention Science: From Design to Implementation discusses multiple approaches for developing and advancing interventions at the individual, family, community, health system, and policy level. The book focuses on creating interventions suitable for diverse populations from racial, ethnical, geographical, and socioeconomical perspectives. Combining best practices with a practical approach, the book enables readers to advance their intervention research. It covers intervention design, data capture in trials, and evaluation. Decision trees help illustrate when to move forward with an implementation relative to the need for further work.
