Lifetime frequency of oral cancer exams


CORALEXAMNO is a 2-digit-numeric variable.

0: Not in Universe
96: 96+
97: Unknown-refused
98: Unknown-not ascertained
99: Unknown-don't know


For sample adults who ever had an exam for oral cancer (CORALEXAMEV), CORALEXAMNO reports the respondent's lifetime number of oral cancer exams.


In the event that the respondent was not readily able to provide an answer, the Field Representative's Manual advised the interviewer to, "Ask for an approximate number. If the SP still cannot provide an answer, mark 'DK' and ask (the next question)."

The next question (CORALEXAM10) asked respondents if the number of lifetime exams exceeded 10 or 20.

For more information, please see CORALEXAMEV.


CORALEXAMNO is only available in 1992.
