Data Collection

Variation in data collection methods can contribute significantly to differences in results among studies that examine similar research questions. When reviewing estimates of the uninsured population the reader will want to consider the following questions regarding data collection:

• How are the respondents contacted? Are phone interviews, face-to-face interviews, or surveys employed?

• Is information collected prospectively or retrospectively?

• How often are respondents contacted? What is the recall period? Are participants asked to recall information from the past month, several months, or year?
