 The implementation study also will include a document review to understand how the AFI project administrative structure and project design may influence project outcomes. Written documentation of the number and roles of staff and volunteers involved in the IDA project and in the organization itself, project rules, and overall project goals and objectives will set the context for identifying variables that could affect participant outcomes. Project communication materials provided to project participants, such as recruitment flyers, orientation materials, and program welcome letters, will be collected to understand project messaging. In addition, we are obtaining data that the projects are collecting, such as data on service take-up.
