Hi,

Sorry if this has been talked about before, I wasn't able to find it in the forum.

I want to create some surveys for workers from amazon turk to answer.

In amazon turk they suggest:

Template note for Requesters - To verify that Workers actually complete your survey, require each Worker to enter a unique survey completion code to your HIT. Consult with your survey service provider on how to generate this code at the end of your survey.

Is there an easy way to do this with LimeSurvey?
Maybe I can do so in the end message?
Can you put javascript code in there?
Not that I know a lot about web developing but I guess it would be a way to start looking into it...

Thanks a lot!
Carlos

How do the mechanical turk users get into your survey? Do you use tokens or do you just give them a link that can be accessed by anyone?

I was planning to use a link that can be accessed by anyone.
Not sure what "tokens" are...
Is there any documentation about that I can look at?

There are ways to generate codes in Limesurvey. You can create a equation type question and then create a code with the digits generated randomly. Depending on the length of the code and the sample size of your survey, there is a certain risk that this code repeats. So I would incorporate into this code the SAVEDID of the response somehow. I remember that there was a forum post about how to create such a code a while ago. Have a search in the forum.

This seems to be also something might want to look at:

You won't believe, but there is a manual. You find it here in the menu "Resources".

Hello All, thanks for your help.

I read most of the forum entries and I came up with a solution for a situation where the survey is public (no participant list) and you want to use it with MTurk (you need a unique 6 digit code at the end for each pariticipant). I am planning on having 200 assignments/workers for my survey.

I would appreciate if you could give your comments to my solution, maybe there is an error I do not see.

I use the question type "equation", give it the name PIN, and hide it.
The code I post in the question section is the following:

{rand(100, 999)}{if(strlen(SAVEDID) < 3, 0, '')}{if(strlen(SAVEDID) < 2, 0, '')}{SAVEDID}

This allows for a participant ID up to 3 digits but puts a random 3 digit number in the front.

Thanks for your comments.

Best,
Max
