Is it okay to use a 5-point Likert scale and a 6-point Likert scale in different sections of the same questionnaire?
Hi! I’m an undergraduate student currently working on our research, and I’d like to ask for advice regarding our questionnaire.
Our questionnaire has two independent sections that measure different constructs:
Behavior - 5-point Likert scale
(Never-Always)
Perception - 6-point Likert scale
(Strongly Disagree-Strongly Agree)
These are separate constructs, and we are not planning to combine them into one overall score or compare/correlate the two scales. We simply want to analyze and interpret each section separately.
So my question is: is it statistically/methodologically acceptable to have different Likert scales in different sections of the same questionnaire, when the sections measure independent constructs and each section has its own separate computation and interpretation?
Thank you!
