Hello Mohmmad,
if you want to know how many people are in the low, medium or high PSS groups, I'd recommend using "Recode into Different Variables" to recode the PSS_sum_score into a new variable, PSS_level, say, and then using the Frequency command on that.
Running Frequencies on PSS_sum_score itself will just tell you the frequency of 0s, 1s, 2s, etc, as is seen in the output you shared - the value labels are purely labels and don't change how SPSS treats the data.
I'm not sure why you'd want to calculate means and SDs of PSS in the three groups, but if you really want to do that you could use your new PSS_level variable as a grouping variable when asking for means and SDs of your PSS_sum_score.

Subject: Perceived Stress Scale (PSS) calculation
Dears,
I am new to SPSS with started with trial version. I have a data for Perceived Stress Scale with 10 scale with 0 - never 1 - almost never 2 - sometimes 3 - fairly often 4 - very often.
I added up the scores for each item to get a total score in SPSS, I did the following steps in SPSS: here is the link for source document ((https://www.das.nh.gov/wellness/docs/percieved%20stress%20scale.pdf)
- I compute variable with PSS_sum_score and label this variable as follows:
- ►with Scores ranging from 0-13 would be considered low stress.
► Scores ranging from 14-26 would be considered moderate stress.
► Scores ranging from 27-40 would be considered high perceived stress.
When I calculate the frequency its giving me very strange table (see last image). I want the means and SD of low, moderate and high perceived stress, can anyone please help me. Billions of thanks.
