Authenticated CAWI links composition

Compatibility:IdSurvey 5IdSurvey 6
X

With IdSurvey you can create anonymous or authenticated CAWI surveys. Anonymous CAWI are those with one generic link (same for all respondents) where you won’t be able to associate the link of the survey to a specific person.

Authenticated CAWI are those with several univocal links, one for each respondent. With univocal links you will be able to associate a person to each interview and the respondent will be able to stop and resume the interview at any moment. IdSurvey user has 3 different options to administer an authenticated CAWI survey. For all three options he will need the general CAWI link.

From IdSurvey 6 onward, the software automatically exports univocal links using the “Export” function in the gearwheel button of the “Contacts Management” section of each survey. Those links will be added to a new column in the excel file, one for each contact. Links generated this way uses the RGI field, same as if they were create by using method 3 of this guide.

General CAWI link

The general web link is needed also for authenticated CAWI. To get it the user has to enter the “Settings” section of the survey menu and then click on “Create link” in the CAWI tab.

Let’s see now what the three options are:

1. Authenticated CAWI with Username e Password:

In this case each respondent will have his username and password that you will have to set in the Contacts file (under Contacts Management section). In the Excel file that you import in Contacts Management, you will have to include the “Username” and “Password” columns, where you will specify for each respondent in the list the univocal credentials.

Then, you will need to send the Generic link to each respondent, along with its Username and Password. 
At the beginning of the interview the respondent will be asked for credentials to enter the questionnaire that can be suspended and resumed at any moment.

 

2. Authenticated CAWI with link (with Identification):

Each respondent will be provided with a univocal link composed by the generic link and the contact id.
You need:

  • to get the generic link that you find in the “Create link” box
  • to add a “Identification” column in the Contacts Management file, where you can insert a univocal alphanumeric code for each respondent.

So, for example, if a respondent’s identification code is CT2378, the link will look like this:

Where the &idc= string introduces the identification code.

To ease the creation of a lot of univocal links, we suggest using the Excel “Concatenate” function.

Open Excel and create a file with 3 columns:

  1. the generic link (copied in as many cells as the total number of links you need to create)
  2. the string &idc=
  3. the list of all Identification codes you created in the Contacts file

Now go to the fourth cell of the first row and enable the “Concatenate” function (Formulas -> Text).
Select the generic link column as “Text1”, the &idc= string as “Text2” and the Identification column as “Text3” .

Now, starting from the first cell at the bottom right angle, drag the pointer to the end of the list.
Univocal links, to send with your preferred email sender, are now ready to go!

 

3. Authenticated CAWI with link (with RGI):

Each respondent will be provided with a univocal link composed by the generic link and the RGI code. The RGI is a univocal complex code automatically associated by IdSurvey to each of your survey’s contact. You can see it in the top part of each contact profile under Contacts Management.

To obtain all RGI in one action, we suggest to use the “Export from file” button:
1. go to Contacts Management
2. click on the gearwheel button
3. click on Export from file
4. export all contacts
5. open the file with Excel and save the RGI column with all the codes

You need:

  • to get the generic link that you find in the “Create link” box
  • to obtain the RGI codes of all contacts.

So, for example, if the RGI code of a respondent is b2c3f425-6dd3-41d2-8ba1-8a3c4e7c958e, the link will look like this:

 http://demo.cawi.idsurvey.com/default.cshtml?id=f3b9ff9e-5681-4d23-82f0-be9b125d89a8&idc=b2c3f425-6dd3-41d2-8ba1-8a3c4e7c958e 

Where the &idc= string introduces the RGI.

To ease the creation of a long list of univocal links, we suggest to use Excel’s “Concatenate” function.

Go to Excel and create a file with 3 columns:

  1. the generic link (copied in as many cells as the total number of links you need to create)
  2. the string &idc=
  3. the list of all RGI codes

Now go to the fourth cell of the first row and enable function “Concatenate” (Formulas -> Text).
Select the generic link column as “Text1”, the &idc= string as “Text2” and the RGI column as “Text3” .

Now, starting from the first cell at the bottom right angle, drag the pointer to the end of the list.
Univocal links, to send with your preferred email sender, are now ready to go!
