Summary

Likert items are widely used in HCI research both as a convenient measure on their own and in questionnaires to give a unified instrument. Researchers often have questions about how best to format Likert items and this chapter looks at the most common issues of the number of response options, whether to have a midpoint and how to label the options. There are clear recommendations based on the state-of-the-art research on these topics.
