Response rate

Monitoring the response rate

• Open rate: Use an email client which can let you see which and how many respondents opened your email. Some email clients will also let you see who clicked on the link.

• Click-through rate. In the results tab, session table, you can see one row for epi respondent who visited the app.

• Start rate. You can then see how many respondents made a meaningful start to the interview eg by saying yes they are ready to proceed.

• Completion rate. This is the number of respondents who actually get to the end of the interview such that Qualia closes the interview correctly.

Improving the response rate

• Open rate.
• The email should come from an actual person known to and ideally trusted by the respondent.
• The title should be short and interesting .

• Click-through rate.
• Use some of our suggestions to provide a clear simple and engaging call to action.
• Explain that other people have usually found the interview to be interesting and enjoyable.
• Put appropriate caveats and technical information further down in the email but not in such a way that respondents feel they have to read every letter before they click the link.

• Completion rate.
• This is a bit more challenging than with some other kinds of data collection because it is not possible to give a precise feedback about how far through the interview is at any point, Because Qualia does not follow a preset set of questions.
• There is an orange progress bar underneath the respondent text box which gives some visual feedback.
• Qualia is instructed to also provide verbal feedback like “we are nearing the end of the interview” as far as this is possible.
