Description

CANSTUDY indicates if the sample person participated in research study or clinical trial as part of their cancer treatment. In 1992, this inquiry was directed at sample persons age 18 years and over who were ever diagnosed with one kind of cancer (CANCEREV, CANCERNO) and were diagnosed in the past 10 years (CAN1DIAGDY, CAN1DIAGE) or who were diagnosed with more than one kind of cancer (CANCERNO) and most recent cancer was diagnosed in the past 10 years (CANRECDIAGDY, CANRECDIAGE). In 2010 it was asked of sample adults age 18 and over who were ever told they had cancer (CANCEREV).

In 2010 respondents were directed to base their answer off of all their experiences since the first time they were diagnosed with cancer.

In 1992 the field representative's manual defines research study or clinical trial as "a study in which the risks and benefits of two or more treatments are compared. Treatments can include different methods or can compare two or more different drugs".
