Hello,
What do you think about the Likert scale? When should we use 5 or 7 echelons? Is the mid neutral point could constitute a problem when the majority of the responses are aligned on this neutral point?
Thanks for your help.
Hi Moez Bellaaj ,
Although it is generally used 5 point Likert scale in literature, it is stressed that 7 - 10 points Likert scales are more reliable than the 4 or 5 point Likert scale, in terms of validity and reliability. However, fewer options are recommended for younger participants. Briefly, this depends on your participants' type.
Another point is to give a decision about whether you really need to use 'neutral point'. Because participants generally tend to mark 'this neutral point' when if :
1. they don't have any idea about the issue.
2. they don't understand the issue exactly.
3. they are not interested in the issue at all.
4. they are in balance between the points etc.

Thanks for these insights Siyabend Kaya
However, when a 5 points Likert scale validated by other authors to measure a particular concept exists, could we replace the five echelons by seven or ten? Changing the scale could have an impact on comparing results or losing benchmarks. What do you think?
Hi again Moez Bellaaj ,
There are a few ways to do this.
For details, I am leaving here a good discussion which has already been done.
