Questionnaire Pre-Test Study

Completed

Conditions studied: Cancer

In brief

Background: The Division of Cancer Epidemiology and Genetics does research into the causes of cancer and ways to prevent it. It uses data from questionnaires. Sometimes, pre-testing a questionnaire with a group of volunteers can help researchers find errors in it and learn ways to improve it. Objectives: To test a questionnaire for problems that might cause response errors and to develop ideas for improving it. To test how long it takes people to complete it. Eligibility: Adults ages 35-75. Volunteers both with and without a history of tobacco use and with or without a family history of cancer are needed. Design: Participants will be screened with a phone call. Participants will be told what background data to bring to the 1 study visit. An interviewer will give the participants the questionnaire. It will be done with pen and paper. It will take about 1 hour. There will be multiple-choice and open-ended questions. They will be about lifestyle, medical, and environmental factors. Some of the questions will be about possibly illegal or highly sensitive behaviors. Participants will note any questions that they find hard to answer for any reason. They will be asked to answer the best they can, but they can skip any question that they prefer not to answer. The personal data of participants will be deleted when the study is done. The interviewer will observe participants while they do the questionnaire. He or she will look for things like long pauses and confusion. Participants will discuss the exam with the interviewer after they finish. This will take about 1 hour.
