Likert-type scales are often used in survey instruments, and practitioners and researchers need to clearly understand the appropriate use of a midpoint in these scales. The authors of this article explore research studies from various disciplines to indicate that there are circumstances when a midpoint should be included and others where it should not. They provide tables, summarizing the benefits and problems in each case as well as evidence-based strategies to employ.
