A Likert scale is a psychometric scale used in surveys to measure the degree of agreement or disagreement with a statement, typically using five response options ranging from Strongly Disagree to Strongly Agree, developed by Rensis Likert in 1932.
Likert vs Likert-Type Scale
A true Likert scale is a composite of multiple items designed to measure a single underlying construct, where the scale score is the sum or average of all item scores. What most people call a "Likert scale" in everyday use is technically a Likert-type item - a single question with a symmetric agree-disagree response format. The distinction matters in academic research; for applied research and CX surveys, the terms are used interchangeably.
5-Point vs 7-Point Likert
The most common choices are five-point and seven-point scales:
- 5-point scales are easier for respondents, produce higher response rates, and work well on mobile. They are the standard for most applied research and CX programmes.
- 7-point scales provide more data granularity and are preferred in academic and clinical research where precision matters.
- 4-point scales (no neutral midpoint) force a directional response and eliminate the "neither agree nor disagree" escape option.
Consistency across a survey and across research waves is more important than the specific number of points chosen.
Design Best Practices
Common Likert scale design errors include: inconsistent scale direction across questions, scale labels that are not symmetric or equidistant, and mixing Likert items with frequency or intensity items in the same matrix without distinguishing the scale type.
The AI Survey Advisor reviews Likert scale design before deployment, flagging scale inconsistencies and reversed-direction errors.
Likert in Survey Platforms
Major survey platforms handle Likert scales through matrix question types. In Qualtrics, the Matrix Table question type supports full Likert formatting with customisable scale labels. In REDCap, Likert items are implemented as radio button fields. In Google Forms, the Linear Scale or Multiple Choice Grid question types approximate Likert format.
Frequently Asked Questions
Five-point scales are the most common in applied research and CX surveys. Seven-point scales are preferred in academic and clinical research where greater precision is needed. Consistency in scale use is more important than the specific number chosen.
A Likert scale specifically uses agree-disagree response options. A rating scale is broader and includes any scale used to measure intensity, frequency, satisfaction, or quality. NPS and CSAT are rating scales but not Likert scales.
Including a neutral midpoint allows respondents who genuinely have no opinion to express that. Removing it forces respondents to take a directional stance, which can be useful when you need clear directional signal.
Pirai AI identifies Likert scale items in source documents from their structure and maps them to the appropriate question type in the target platform. Matrix questions with consistent scale labels are preserved as matrix question types.
