Answering machines are now more frequently encountered in telephone studies than just a few years ago. Researchers must devise new techniques to compensate for the increased use of answering machines. The main point of the Michigan Higher Education Institute (MHEI) 800 number study was to establish if leaving an 800 call-in number on an answering machine would increase response rates and lower the number of interviewer initiated call-backs for call attempts resulting in an answering machine disposition. The MHEI study provided a chance to look at how an 800 number could improve response rates in a panel telephone study. The technique worked well, 11.6 percent (n=87) of the completed interviews came from call-in's, 6.5 percent from all answering machine contacts.
