The P.E.P. Report 1969-1973 focuses on the various findings and activities of the Program Evaluation Project. Followup is an integral part of a goal oriented evaluation, providing the opportunity for the collection of various forms of outcome data as well as consumer satisfaction information. This chapter discusses the history and implementation of the followup program for the Program Evaluation Project, including the development of a questionnaire, training of the interviewers, locating and contacting participants, and costs. The second section discusses the various studies in which the followup unit was involved, including the original reliability study in which clients were followed up by two different interviewers at two distinct points in time, the interdisciplinary reliability study which discusses the comparison of R.N. and M.S.W. interviewers and phone versus in-person interviews, the followup program for the Crisis Intervention Center, and the followup of clients terminated from the Hennepin County Mental Service prior to involvement in treatment.
