Data Quality Team and the FS, RS, and RD. If the Field Verifier found the work to be invalid, he
or she reworked the case.
In general, the need for such in-field verification was limited, but it did occur. In the 2003
NSDUH, a total of 451 cases were selected for field verification. This process led to the
identification and termination of FIs who were determined to have submitted fraudulent work.
All their work completed during the current quarter was verified and reworked as necessary. A
total of 24 invalid interviews and 34 invalid screenings involving 6 FIs were identified via inperson
field verification. The 4 FIs with falsification were terminated. The other 2 FIs had made
enough errors to cause a total of 6 screenings to be invalid, but no clear evidence of falsification
was found. These 2 FIs were placed on probation, retrained and placed on increased verification.
8.4.3 Verification Monitoring Tools
8.4.3.1 Case Data Information Link
The Verification Status on the Case Data Information link on the CMS allowed project
staff to view the verification status of each case and monitor trends across status codes or areas.
The following Verification Status codes were used to monitor the verification at the case level:
NF: No Form (Code 70s)
NP:
RE:
NS:
ST:
SF:
SM:
OK:
UC:
UN:
SS:
IR:
IW:
No Phone
Refusal—not selected
Eligible, but not randomly selected for verification
Selected for Telephone Verification
Selected for Field Verification
Selected for Mail Verification (Code 70s without phone numbers)
Completed Okay
Finalized—Unable to Contact
Finalized—Unresolveable
Completed—Some shortcuts
Completed—Invalid, then reworked
Completed—Invalid, not reworked
Since verification selection was random, it helped to see which cases had been selected. If
project staff wanted additional cases to be selected for verification, they worked with their
region's DQC to select additional cases to be flagged for verification.
