Likert scaling is one type of response to items in a questionnaire or tool. For example, Likert scaling would have you rate an item such as “I am satisfied with the care I received” on a scale using a 1-to-5 response scale where:

• 1 = strongly disagree
• 2 = disagree
• 3 = undecided
• 4 = agree
• 5 = strongly agree

You will find various options and scaling methods for the number of response choices (1-to-7, 1-to-9, 0-to-4). Odd-numbered scales usually have a middle value that is labelled Neutral or Undecided. Some tools used forced-choice Likert scaling with an even number of responses and no middle neutral or undecided choice.
