Within the industry, there are many strong opinions on survey scales, which have pros and cons to each. The UX research team offers the following guidelines:
Stick to a consistent rating system. If your survey contains rating questions, it’s ideal to use the same scale for each of your questions. That way, it’s easy for respondents to adapt while avoiding potential mistakes. The last thing you want is to ask a question with a 1-5 scale, then ask another question in the survey with a 5-1 scale. Most likely, respondents will answer the second question incorrectly, with the previous scale in mind.
That being said, there are situations when you may want to randomly reverse the scale order for the same survey rating question. This is sometimes done if you’re using rating questions to obtain quantitative data.
