Numbered MemosBRFSS POLICY MEMO 94.4 This version of the the Rules of Replacement supersedes the document transmitted March 24, 1993 as BRFSS Policy Memo 93.1. The new rules reduce the expected number of attempts for each phone number during each calling occasion from 4 to 3. Thus, the maximum number of calls required before a phone number is replaced will now be 15 instead of 20. Prescreening of phone numbers for Waksberg sampling is also subject to this change. The call history section on page 1 of the printed 1995 questionnaire that we will be sending to you in early December will be revised accordingly. Ci3 and CASS CATI programming will also conform to this change. The new rules should be implemented beginning with January 1995 surveillance, i.e., January 1995 interviewing including Waksberg prescreening done in December 1994. BRFSS RULES OF REPLACEMENT
