Do you have one or more reference resources that you can recommend for the necessity of reverse coding/scoring in surveys?
Actually, reverse coding is an older strategy that is no longer recommended because too many respondents get confused by it and answer questions in the wrong direction, which reduces your reliability.
Hatice İlhanlı, if I understand your question correctly, I assume you have a survey/scale that contains negatively worded, as well as positively worded, items. If that is the case, and the negatively worded items need to be reverse coded, I think the process of reverse coding is so commonly practised and intuitively sensible, that no references to support it are necessary.
Hi
Using reverse code is a strategy for scaling questions that are theoretically in conflict with other questions. This is done only on the basis of sufficient background and theory, and in this case the researcher must be sure that the content of the question is different from the rest of the questions. This is logical and there is no specific reference for it.
David L Morgan and Robert Trevethan I agree to both of them, there are many Youtube videos you can watch to reverse code.
Some researchers use negatively worded items on a survey instrument to contain acquiescence bias; however, the effect of such a strategy on response accuracy and instrument validity could preponderate its benefits. In other words, mixing positively and negatively worded items on a survey instrument might beget threats to its validity and reliability—unless done carefully. The following could be of interest.
