Abstract:
Surveys continue to be an important research methodology. However, when assessing survey studies, clinicians should review the response rate and consider potential selection bias. Methods of survey administration (electronic, postal, or other means) may differ in cost, missing data, and response rates. In addition, reviewing the questionnaire construction, including the understandability of the questions and response formats, is important in assessing the validity of findings.
