What the paper says
ABSTRACT Although widely used in survey research, the application of the Likert scale often lacks rigorous justification in relation to key methodological decisions. Furthermore, inconsistencies in terminology persist, for example, the common reference made to the “5‐point Likert scale,” even though debate is ongoing about the optimal number of response categories. Using a narrative review approach, this paper provides researchers with a concise, evidence‐based guide for the appropriate use of Likert‐type scales in survey research. Drawing on existing literature on itemized rating scales, particularly the Likert scale, the paper identifies the frequently overlooked critical decision criteria for anchoring the Likert scale. It clarifies essential considerations such as the number of scale points, inclusion of midpoints, labeling of response categories, and response format presentation. As a practical contribution, the paper offers evidence‐based guidelines to help researchers make informed decisions when employing Likert‐type rating scales in survey research.
