Survey split

We want to split the survey but give people the option of continuing directly to Part II at the completion of Part I. I don't see a way to do this with separate surveys in Qualtrics, but we can just add the Part II questions in the Part I survey after a question about whether the person would like to continue:
Congratulations, you have completed the fingering exercise survey. Thank you for sharing your expertise.

The next step would be for you to answer some questions about your background and attitudes about fingering. Completing this "player profile" will earn you a chance to win another $100 Amazon gift card and will make the fingering data you have just provided even more valuable to our study. Would you like to do this now?
  • Yes, I have time.
  • No, maybe later.
If the subject says yes or no, we add her name, email, and response ID to the "Survey I Complete" panel (via a panel trigger) and send her a thank you email that includes the consent agreement.

If the subject says yes, we press on. When she complete the survey, we add the subject's name, email, and response ID to the "Survey II Complete" panel. We also send a thank you and copy of the consent agreement via an email trigger.

(Another important change: Add a panel trigger to add the user to the "Lottery I" panel if she says yes to participating in the Part I lottery. Do the same for the Part II lottery. This will make it easier to process the survey awards. Unfortunately, or perhaps fortunately, this mechanism cannot be used to capture contact information from people who do not complete the survey within two weeks and effectively withdraw from the study. This is because the panel updates are only triggered on survey completion. Moreover, I can't delete all information about a person while still maintaining her contact information. So I am changing the consent form to promise compensation only for in-person sessions that are terminated early. Whew.)

If the subject says no, we add her information to the "Survey II Separate" panel, so we can follow up with her later. The profile part will be advertised to members of this panel as a separate, abbreviated survey.

Lottery II contact information for this follow-up survey will be written to the "Lottery II" panel and derived from the "recipient information," which should be available because we will be using unique survey links (from the "Separate" panel) for all surveys but the first one.

Should we include a second question about participating in the lottery for the integrated Part II? What about the standalone Part II? I say yes to both.

The progress bar is really discouraging, since it includes a bunch of future questions that a lot of people won't be answering and also because it does not have any notion of weighting the effort required for a given question. The progress bar creates a distinct impression that very little progress is being made. So I am not going to show it in Survey I and am instead including a heading (e.g. "Exercise 1 of 7") at the top of each fingering exercise. This should give the subject a better sense of progress. I just wish I could start the progress bar for the embedded Part II, but this does not seem possible. So they will have to do without.

Per BDE's request, I am also changing required to initial when talking about the survey activities in the consent agreement.

These changes will be made to version 5 of the survey (now surveys).

I must add our single v4 respondent to the "Complete" and "Lottery" panels manually.

Also, the follow up survey must write the original "${e://Field/ResponseID}​" value (extracted from the panel data field "TriggerResponseID") to an embedded data field called "TriggerResponseID." Then we should be all set. This should add only minor complexity to the previously planned data plumbing. We just have another opportunity to use "TriggerResponseID," and whatever process loads the data to MySQL will have to be a teeny bit smarter. While I still need validate all this end to end, I am quite certain it will work.
