Description

For sample adults aged 40 and older who ever had a colonoscopy (COLEV) and who chose to respond in time period format, COLLNO reports the number of time units (how many days, weeks months or years ago) since the respondent had their colonoscopy. COLLTP reports the type of time period (in days, weeks, months, or years) corresponding this variable. These two variables should be used together.

The survey form directed interviewers to, "Enter number for time since last colonoscopy," and "Enter '95' for 95 or more."

For more information, please see COLEV.
