Likert Scale has been widely in use for more than 80 years (it was published in 1932). However, the limitations of it are well-known:
- The space between each choice is possibly not equidistant.
- People keep endorsing the mid-point of the scale and avoid choosing the “extremes" options on the scale, even if an extreme choice would be the most accurate.
- Attitudes of the population for one particular item in reality exist on a vast, multi-dimensional continuum. However, the Likert Scale is uni-dimensional and only gives 5-7 options of choice
- Peoples’ answers will be influenced by previous questions
What is the latest development in Psychometrics? Is there any budding and promising replacement or advancement for Likert Scale?
