Because inexperienced FRs are more likely to falsify, more of them are selected for reinterview each month: three groups of inexperienced FRs to two groups of experienced FRs. Since inexperienced FRs falsify a greater percentage of cases within their assignments, fewer of their cases are needed to detect falsification. For inexperienced FRs, five households are selected for reinterview. For experienced FRs, eight households are selected. The selection system is set up so that an FR is in reinterview at least once but no more than four times within a 15-month cycle. A sample of households assigned to the telephone centers is selected for QC reinterview, but these households become eligible for reinterview only if recycled to the field and assigned to FRs already selected for reinterview. Recycled cases are included in reinterview because recycles are more difficult to interview and may be more subject to falsification. All cases, except noninterviews for occupied households, are eligible for QC reinterview: completed and partial interviews and all other types of noninterviews (vacant, demolished, etc.). FRs are evaluated on their rate of noninterviews for occupied households. Therefore, FRs have no incentive to misclassify a case as a noninterview for an occupied household. Approximately 2 percent of CPS households are assigned for QC reinterview each month. REINTERVIEW PROCEDURES QC reinterviews are conducted out of the regional offices by telephone, if possible, but in some cases by personal visit. They are conducted on a flow basis extending through the week following the interview week. They are conducted mostly by senior FRs and sometimes by program supervisors. For QC reinterviews, the reinterviewers are instructed to try to reinterview the original household respondent, but are allowed to conduct the reinterview with another eligible household respondent. The QC reinterviews are computer assisted and are a brief check to verify the original interview outcome. The reinterview asks questions to determine if the FR conducted the original interview and followed interviewing procedures. The labor force questions are not asked. 1 The QC reinterview instrument also has a special set of outcome codes to indicate whether or not any noninterview misclassifications occurred or any falsification is suspected. RE reinterviews are conducted only by telephone from both the telephone centers and the reional offices (ROs). Cases interviewed at the telephone centers are reinterviewed from the telephone centers, and cases interviewed in the field are reinterviewed in the field. At the telephone 1 Prior to October 2001, QC reinterviews asked the full set of labor force questions for all eligible household members. centers reinterviews are conducted by the telephone center interviewing staff on a flow basis during interview week. In the field they are conducted on a flow basis and by the same staff as the QC reinterviews. The reinterviewers are instructed to try to reinterview the original household respondent, but are allowed to conduct the reinterview with another knowledgeable adult household member. 2 All RE reinterviews are computer assisted and consist of the full set of labor force questions for all eligible household members. The RE reinterview instrument dependently verifies household membership and asks the industry and occupation questions exactly as they were asked in the original interview. 3 Currently, no reconciliation is conducted. 4 SUMMARY Periodic reports on the QC reinterview program are issued showing the number of FRs determined to have falsified data. Since FRs are made aware of the QC reinterview program and are also informed of the results following reinterview, falsification is not a major problem in the CPS. Only about 0.5 percent of CPS FRs are found to falsify data. These FRs resign or are terminated. Results from the RE reinterview are also issued on a periodic basis. They contain response variance results for the basic labor force categories and for certain selected other questions. REFERENCES Bushery, J. M., J. A. Dewey, and G.
