Description

CNBLAD identifies sample adults who had ever been told that they had bladder cancer. Those sample adults who reported ever being told by a doctor or other health professional that they had cancer or a malignancy of any kind (CANCEREV) were asked the follow-up question, "What kind of cancer was it?"

Interviewers marked up to three kinds of cancer specified on the survey form, and noted when the respondent mentioned more than three types of cancer. For 1997 forward, the Field Representative's Manual directed: "Count the same type of cancer or malignancy on different body parts as only one kind. For example, malignant moles on the face, neck, and trunk should be counted as only one kind of cancer." Interviewers were further directed to not read the answer categories on the survey form to respondents. If the respondent used a technical term not on the form, then the interviewer was to "ask what part of the body this affected and enter that"; if the answer did not fit a category on the form, then the interviewer was to mark "other" and write down the response.

The coded responses to "What kind of cancer was it?" were the basis of a series of dichotomous variables, each indicating whether a particular type of cancer, such as bladder cancer, was mentioned by a respondent who was ever diagnosed with cancer.

Comparability

With the exception of the NHIS questionnaire redesign introduced in 2019, this variable is completely comparable over time. The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content.
