Can respondents go back to previous questions to review or change their answers? Are there any restrictions on backward navigation in different survey modes? Can we control whether the back button is enabled or disabled?
Before synchronising the data, the interviewer can change the data even if the schedule is completed. But, once the data are synchronised, the responses can be edited only after a rejection from the supervisor.
To provide a complementary answer, whereas other CAPI systems have a default of linear progression, Survey Solutions has a its default the freedom to move around within a questionnaire. Among other reasons, this design choice is in recognition that interviews, while structured human conversations, are not always linear (e.g., move backwards to revise an answer, move to the roster row of an available respondent rather than be stuck waiting for the person who happens to be in the next row, etc.). Accordingly, the CAPI application should not be either.
