POP study stepped-wedge RCT design
Legend: Schematic of the stepped-wedge RCT design. Each building will be randomized to one of 4 waves during which they will receive the 6-month technical assistance intervention. There is a 1-month break/buffer period between each wave to facilitate measurement (e.g., staff surveys and fidelity checklist completion) and preparation for the subsequent wave. Not shown in the figure is that formal measurement of sustainment will occur for each building in the 8th month following wave completion
