I have two questions : Q1: (1-Strongly Disagree.....5- Stronly Agree) which contains several statements to measure certain factor. in the same time I have another questions Q2 in different way (1- Always ...5-Rare) some of there statements measure Q1, and the opposite is right also. Here the two measures are opposite ( Scale 1 in Q1 = scale 5 in Q2). SO
Kindly, How can I do that in SPSS ???
With a particular question you can code either way. I would usually expect them to be in a similar "direction" if there were about the same "type" of response- such as an importance of something , support of something, opinion on something etc.
However the good news is- however they are coded you have the ability to recode into another variable and this you can swap them around . SPSS allows you to recode.
I believe in some surveys by mixing the 'direction' around you avoid the respondent just ticking the same box all the way down?
To create a scale, all of the items should be in the "same" direction, so that all the items within that scale have positive correlations. Once you have all the items in the same direction, you should assess the scale using Cronbach's alpha.
Because there have been so many questions on this topic, I have assembled a set of resources, here:

Thank you David for those links, however the first two links where broken.
There is only one link (which does spill over onto two lines). You should be able to reach it just by clicking on it, but if not, you can use the ResearchGate Search function to find it:

Every question should be in same direction. But you can decode response sheet either in SPSS or Excel.
Dear Masound,
You can simply use Recode command in SPSS syntax to transform the variable int the same direction(e.g. with same 1-5 scale).
Do let me know in case of any queries.
