How to Interoperate Inquisit Web with Online Survey Packages such as Qualtrics and Survey Monkey

Inquisit has full-featured capabilities for designing and administering questionnaires and surveys. In some cases, however, you may wish to insert an Inquisit cognitive task into an existing survey on another site such as Qualtrics, Sona, or Survey Monkey. Inquisit Web has features in place to smoothly transition participants back and forth between Inquisit and other web sites. This is accomplished by automatically forwarding participants between the survey and the Inquisit task. .

Most survey sites allow you to forward participants to another web site after they've completed a survey. You need only specify the address of your Inquisit launch page as the forwarding url, and your participants will be automatically forwarded to the Inquisit portion oft he study when the survey is complete.

Similarly, Inquisit allows you to specify a "Finish Page" where it will forward participants after they've completed the Inquisit part of the experiment. Here you would specify the address of the survey, and Inquisit will automatically send participants to that address once the Inquisit task is complete.

Sharing Participant IDs Between Web Sites

To map each participant's survey responses to their Inquisit data, you will need to share a common unique id for each participant between Inquisit and the survey. This id must be recorded in the data sets from both web sites so that survey responses can be correlated with Inquisit task outcomes for each participant. There are a couple of different strategies for sharing ids.

User-Entered Subject IDs

A simple way to share ids between Inquisit and another site is to require the participant to enter some identifier - for example, a preassigned number or an email address - at the beginning of both the survey and the Inquisit session. When registering your Inquisit online experiment on, you can specify that participants should enter the id in the experiment settings. Alternatively, you could add the question to the Inquisit script itself, and then include the response in data to be recorded.

Sending Subject IDs from 3rd Party Site to Inquisit

A less error prone way to share participant ids is to embed the id in the forwarding address between Inquisit and the other web site. When forwarding from the 3rd party survey to Inquisit, for example, they survey must dynamically add the id of each participant to the address of the Inquisit study as a "query parameter", which is a standard mechanism for sharing data between different web sites. Below, we show how to set this up in Qualtrics. For other platforms, consult their support resources for specific instructions.

Forwarding from Qualtrics to Inquisit

  1. Log into Qualtrics and selected your survey project
  2. Click the Survey Options button
  3. Within Survey Options, go to the Survey Termination section
  4. Select the option to Redirect to a full URL
  5. Enter the address of the launch page for your Inquisit test, e.g.,
  6. Add the query parameter ?subjectid=${e://Field/ResponseID} to the end of the address

If the address of your Inquisit test is "", for example, the complete forwarding url would look as follows:${e://Field/ResponseID}

The subjectid part of the URL specifies the name of the query variable. This variable is set to the value returned by ${e://Field/ResponseID}, which is an example of Qualtrics "Piped Text" that you to insert variables into a survey. This particular variable inserts each participants unique response id. For example, when participant with response id "1234" completes the survey, Qualtrics will forward them to the following url:

Once participants are forwarded to the Inquisit launch page, Inquisit will extract the value of the subjectid parameter to get their id, and that id will be recorded in the data.

Forwarding from Sona to Inquisit

See Sona's help topic for sharing participant ids between Sona and Inquisit.

Configuring Inquisit to Receive IDs from a 3rd Party Web Site

To configure Inquisit to read the participant id from the query parameter:

  1. Login to the Online Experiments page in your account
  2. Click " edit" next to the experiment
  3. Select the "Subject IDs" tab on the right of the screen (shown in the figure below).
  4. Where it says "Choose how subject ids should be generated, select URLQuery Parameter"
  5. Specify the name of parameter (e.g., "subjectid").
  6. Click the Save button

Query Parameter

That's it. Inquisit will now extract this subject number from the url and record it in the data files.

Returning the Subject ID from Inquisit Back to 3rd Party Site

If you would like to forward the participant back to the survey package at the end of the Inquisit session, you can specify the url to the survey as the Finish Page when running through the experiment registration wizard. Inquisit will then redirect the participant to that web page at the end of the session.

Finish Page

In the above example, Inquisit will forward participants to at the end of the experiment. Do not specify the subject id in the Finish Page url - Inquisit will automatically append the id using the same query parameter that it found when the subject arrived at the Inquisit launch page. To continue with the above examples, if the Finish Page is set to, the actual forwarding url for subject 134 would be:

Your survey package can then retrieve the value of this query parameter to identify which subject is returning to the survey. Now the survey package can pick up where it left off with this participant.

Sending the Subject ID from Inquisit to 3rd Party Sites

If participants start with the Inquisit session before going to the 3rd party survey site, the subject id can be explicitly included on the finish page url so that it can be used by the 3rd party site. Using the above example, the following finish page would include the unique subject id for each participant:<%script.subjectid%>

Add the end of each session, Inquisit will substitute "<%script.subjectid%>" with the actual ids for each of the subjects.
