Why Include Survey Back Buttons?

Many, if not most online surveys in the past have tended to include back and forward buttons as the default setting. The idea is to allow the theoretical prospect of respondents going back to check their answers before continuing with the survey.
Many, if not most online surveys in the past have tended to include back and forward buttons as the default setting. The idea is to allow the theoretical prospect of respondents going back to check their answers before continuing with the survey. This probably doesn’t happen too often. On the other hand, some respondents get frustrated if they can’t go back and look at previous questions. So the back button is often left in to serve perhaps a minority of respondents, who could prove to be a vocal minority!
But there are times when disabling the back button is a necessary precaution. For example, if you have some questions before an advert is shown; having seen the advert, the respondent could theoretically go back and change their previous answers, some of which relate to the context of the advert and could bias the results. Again, the chances are relatively small, but possible. This possibility is sometimes a risk not worth taking.
