Analysis plan
REGRESSION, SECONDARY
We will “deconstruct” the intervention for the measurement of adherence to the intervention protocol and use these adherence indices in secondary analyses. Adherence data will be collected based on 1) what, how much, and when individual elements were delivered in each development, and 2) what was reported as received by both study staff and HLAs and by residents. We will collect these data for all intervention levels and all components and will enter these data by level into regression models for intervention residents to determine the relative effects of different levels of intervention on physical activity behaviors. These variables will also be used to create cohorts for sensitivity analyses or stratified analyses.Initial descriptive analyses will include an analysis of the baseline characteristics of participants. Data will be stratified with respect to study groups and the randomization assumption checked by comparing demographic characteristics across groups. Unbalanced characteristics will be included in multivariable models to control for any demographic difference between intervention groups.
