Study design
Following baseline, participating programs were randomly assigned to intervention (4 programs) or control conditions (3 programs). Randomization was stratified so that programs from the same agency were not assigned to the same condition. Survey measurement in all programs was at baseline, and at 6- and 12-months post. Baseline data collection occurred from June to August 2019, and final (12 month) data collection occurred from December 2020 to January 2021. The original plan was for data collection at 6-month intervals, however adjustments necessitated by the COVID pandemic extended the interval to about 8 months.Intervention programs received the intervention between baseline and 6 months, while waitlist programs received training between 6 and 12 months (see Fig. Study design showing clinical trial comparison and pre-post comparison
