What is Reverse Coding? One common validation technique for survey items is to rephrase a “positive” item in a “negative” way. When done properly, this can be used to check if respondents are giving consistent answers.5
When should you do reverse coding?
Before you run a Cronbach’s alpha or factor analysis on scale items, it’s generally a good idea to reverse code items that are negatively worded so that a high value indicates the same type of response on every item.
Why we do reverse coding in SPSS?
In SPSS, when you calculate the Cronbach alpha, there is an option to ask for each item what would alpha be if that item were deleted. More directly, if you do a Principal Components Analysis, the inverse coded items will load negatively on the principal components, which would suggest that reverse coding is needed.
Why is reverse coding necessary?
Reverse scoring is necessary when research instrument developers have purposefully written a group of items with some items in a different direction than others.

What is reverse coding in statistics?
Reverse scoring means that the numerical scoring scale runs in the opposite direction. So, in the above example strongly disagree would attract a score of 5, disagree would be 4, neutral still equals 3, agree becomes 2 and strongly agree = 1.
What is the purpose of reverse coding when summarizing research data?
To do this, a good idea is to reverse score all the items which are “negatively phrased”, so that all variables are consistent. The aim of reverse scoring is to re-code the responses so that a high score is transformed into the corresponding low score on the scale.
What are reverse questions?
Reverse questions are questions that are used as a response to a direct question from a participant or the group. Instead of answering the question, you reverse the same back to the person who asked it.
How is reverse score calculated?
One way to reverse a score is to subtract each participant’s score from the maximum. The maximum might be the maximum theoretically achievable in your test, or the maximum actually achieved among your participants. As a result, low scores will now be near the maximum, and high scores close to zero.
What are reverse worded items?
Many self-report measures include some items worded in the direction opposite to that of other items. These so-called reverse-worded (RW) items can reduce the reliability and validity of a scale, and frequently form a separate method factor that does not appear to be substantively meaningful.
What are some possible disadvantages of reverse scoring items?
1. With reverse coded items you will never know whether a test person understood the question correctly or whether the person missed the reversing of the scale and just used the scale as before. 2.
What are negatively keyed items?
Positively keyed items are items for which agree- ment indicates a higher level of the trait, and negatively keyed items are items for which agreement indicates a lower level of the trait (Furr, 2011).
