No, there is no necessary relationship between the two. You may have more vignettes or fewer vignettes than response categories.

- Frequently Asked Questions
- About this document
- Introduction
- Statistical Analyses with Anchoring Vignettes
- Survey Instrumentation
- Are universally applicable, culture-independent survey questions possible?
- Can I use anchoring vignettes if I don't have variables to predict the thresholds?
- Can I use anchoring vignettes to understand why respondents understand survey questions in such different ways?
- Can we avoid DIF by using a panel design, without vignettes?
- Do I need one vignette for each response category?
- Doesn't Anchoring Vignettes merely move the problem of coming up with DIF-free survey questions back one level (from self-assessments to vignettes), and so in the end you have the same problem?
- How is this strategy affected by the finding in social-psychology that assessments of oneself and others differ?
- How many anchoring vignettes should I ask for each concept I want to measure?
- How much expense will anchoring vignettes add?
- If I have a direct physical measurement, such as a medical test, do I need anchoring vignettes?
- In what order should vignettes and self-assessment questions be asked?
- Is there a simpler way of asking questions so we can avoid any statistical analysis?
- Should I ask vignettes questions of all people or a random subset?
- Should the vignette describe the age, sex, etc., of the hypothetical person? Should it be self-referential?
- What are the requirements
- What empirical evidence do you have that it works?
- What has to go wrong for anchoring vignette corrections to bias my results?
- What issues should I consider when writing vignettes?
- When do anchoring vignettes make the most difference?
- Why Use Anchoring Vignettes?
- Why will anchoring vignettes work when we know that putting educational achievement tests on a common scale has not been possible?
