Five boxes do not make a scale
Use ordered responses within a tested multi-item scale without confusing format, item, score, or validation
Premise
A Likert scale measures an attitude or related latent construct by combining ordered responses across multiple statements. Rensis Likert’s 1932 contribution was not the familiar row of five boxes alone. It was a summated-rating logic in which item analysis identifies statements that work together and their scored responses produce a composite measure.
For executives, this distinction prevents superficial survey design. One satisfaction question with five response options is a Likert-type item, not a validated scale. A defensible instrument also needs a defined construct, an item set that represents it, a scoring rule, and evidence that the combined score behaves as intended.
