This manual includes strategies for conducting wave 4 of a longitudinal follow-up study. Part 1, Procedures for Researchers, outlines steps to be used in guiding the research process to achieve indepth, qualitative interviews with a group of the original sample members who were studied over a 15-year period. It includes guidelines and procedures for project management (securing the sample and human subjects clearance, preparing the research materials, planning for interviewers, handling data from taped interviews) and examples of resources (contact and follow-up letters, receipt for cash payment, points for interviewer/respondent contacts, sample transcription segment). Part 2, Interviewer's Manual and Videotapes, is a procedural training guide covering project history, interviewer's responsibilities, interviewing techniques, survey vs. qualitative interviewing, conducting interviews, location strategies, and the guided interview booklet. It also includes a description of videotapes developed to accompany the manual for use in training interviewers. On tape, regional committee members discuss the manual and show actual interview situations (simulated views and experiences) representative of situations interviewers will likely encounter. The tapes and the manual may be used in group training sessions or read and viewed by individuals. Appendices contain a background sheet for the interviewer, location strategies, and a 30-page questionnaire booklet. (Author/PN)
