 Outcomes will be assessed at two and six weeks after the baseline visit by the Geisinger Telephone Survey and Interviewing Facility. This facility is equipped with 12 computers and runs two shifts a day. The Survey Unit uses a state-of-the-art Windows based Computer Assisted Telephone Interview CATI system to administer surveys and collect research data. The group holds 12 interviewer licenses for the CATI system. Trained and experienced interviewers are available to make the calls from 9 am to 9 pm Monday through Friday and from 10 am to 2 pm on Saturdays.
