Study Notes
Developing and Using Questionnaires
Advantages of Questionnaires
- Easily replicable
- Relatively quick to administer
- Relatively cheap
- Can cover a wide geographic area and large numbers
- Researcher has control over the focus of the questions and the answers
- Anonymity may encourage openness in respondents
- Can be analyzed quantitatively
Disadvantages of Questionnaires
- Very dependent on researcher’s perspectives
- Assumes the respondents understand what the questions mean
- May not be comparable between sub-groups or over time
- Non-responders may differ in their characteristics
- Need to consider relevant characteristics of responders and non-responders
Assessment of Questionnaire Validity and Reliability
Validity
- Face validity: does the instrument cover the constructs fully?
- Content validity: do people understand the instrument and is the content appropriate?
- Criterion-referenced validity: does the instrument measure what it's supposed to measure?
Reliability
- Inter-rater reliability: do users of the instrument administer it in the same way?
- Test-re-test reliability: does the instrument get the same results in the same population?
- Internal reliability: do items in the instrument covering similar constructs give similar results?
Bias in Surveys
Types of Bias
- Sampling bias: inappropriate sampling method
- Exclusion bias: incomplete sampling frame
- Measurement bias: instrument deficiencies
- Non-response bias: people don’t respond
Maximizing Response Rates
- Use multiple distribution methods
- Use multiple contacts and reminders
- Ensure high-quality covering letter and attractive appearance of the questionnaire
- Provide freepost envelopes and incentives
- Add endorsements from funding bodies, local NHS, or professional bodies
Dealing with Non-Responders
- Understand the characteristics of non-responders to quantify bias
- Compare characteristics of responders and non-responders
