PhenX - pre-existing cancer conditions protocol 070801

Pre-existing cancer conditions proto

Definition

This self-administered protocol asks respondents to indicate the year of diagnosis for clinician-diagnosed illnesses. The respondent is also asked to provide the year of first diagnosis. The Cancer Working Group (WG) slightly modified this question from the original protocol text. The original protocol obtains year of diagnosis by asking respondents to choose between three choices (Before June 1, 2003; June 2003 to May 2005; or after June 1, 2005). The Cancer WG removed the phrase "since June 2003" in order to allow collection of diagnoses that occurred prior to June 2003. The additional response options were deleted, and respondents are now asked to write in the four-digit year of diagnosis.
