Call volume is annual, rounded to the nearest 1000. FT/PT = full-time/part-time. Level of staff participation ranged from asking a single screening/eligibility question to being centrally involved in all phases of the project. Data come from sites’ applications, which were submitted in 2014 in response to a request for proposals.
