- Reverse the coding of a variable using SPSS. This technique is useful when you have negatively and positively worded questions on a questionnaire and you need to reverse the coding of the likert scale responses.

Alternatively, a much quicker way to reverse-code a variable is to: Transform > Compute Variable then simply deduct the variable from one whole-number above the highest scale-value. So, using a Likert Scale of 1 to 5; one whole-number above 5 is 6; to reverse code, simply compute: 6 - variable name.
that works for me! thanks!
Thank you so much! Your video was very straightforward and concise and you saved me a lot of time and effort
Which one to do first? Enter data then reverse coding. Or. Set the reverse coding first then enter data?
Thank you so much. Clear instruction and a beautiful voice.
SUPER HELPFUL Thank you - it worked
Hi mujdelicious. Yes, after you reverse the coding then use them for all your analysis rather than the original coding.
Very helpful and concise!
Thanks alot this video saved me tons of hours
THANK YOU SO MUCH! This video is so clear and concise.
hi, thank you so much for the video, it really helped! After this, will I be using the reverse codes in my reliability analysis and factor analysis?
Thanks a lot! you saved me a lot of time and effort
Thank you miss Brunel
Hi Brunel,
Is it useful in case we have a negative cronbach's alpha ?
You use new coding in other to avoid a negative alpha , check her videos above for better understanding.
Do you really need to change the value label after reverse-coding the negative items?
Thank you!!
wth what said at 2:50 was so confusing!!! you said 1 was strongly agree but in the screenshot at the beginning 1 was strongly disagree 🙈 I’m so lost
This is really helpful thanks. But I have a question. when recode which results to include in the research (in my case) the original one or the recoded ? In my case I had to recode all the items because I rated them from strongly agree to strongly disagree so the highest mean score indicated a negative attitude. so i recoded my items to get a positive mean score but which result shall I insert in my paper?
Moon Light you use just the reverse coding for your analysis
What are the statistical implications of not reverse coding negatively worded questions in SPSS in terms of the data analysis? Can it negatively affect the determination of statistical significance?
It affects your Cronbach's Alpha, you might get a negative one
Hi! please may I know if it is necessary to change the value label after recoding, as 1 for strongly disagree to become 1 for strongly agree, likewise 7 for strongly agree to become 7 for strongly disagree ?
main purpose of the reverse coding not to change the lable like strongly agree or strongly disagree .its only change the value like 2,3,4 that is the value of agree or disagree
Do you reverse code when the question is framed the other way? Why?
why did you convert it to ordinal scale
Because her original (un-recoded) variable was an ordinal measure, so this is the same.
what would happen if I do not change?
Hi,
Just wondering if I am doing the recode into the same variable do I need to go ahead and change the value labels still?? And do you recommend doing this process first, or would you go ahead and look at your frequencies?
Thanks :)
not there is no need
