The Likert item question type provides the participant with a Likert item to answer the question (Figure 1). This question type has the following options:
A Likert scale is the sum of responses on several Likert items. There is often confusion in the literature between Likert item and Likert scale.

A well-designed Likert item must exhibit:
Neither agree nor disagree. Omitting the neutral/zero value as an option is described as a forced choice method.
Note: In Psychstudio, a Likert item can be used for any quantitative rating scale even if it is not strictly well-designed symmetrically (such as a pain rating from 1 to 10) or is not well-designed as far as balance is concerned (such as a logarithmic scale of some form).
