MTurk premium qualifications

[Michael]

Hi all:

I'm running a study on MTurk in which I need to use premium qualifications (in my case, political affiliation). https://otree.readthedocs.io/en/latest/mturk.html#qualification-requirements gives an example for a location-based qualification, but I can't seem to find the QualificationTypeId for premium qualifications. Is this doable on oTree, or do I need to use the MTurk UI?

Thanks,

Michael

Sorry for the multiple posts, but has anybody found a good way to deal with this?

I asked Amazon and they recommended creating two types of HITs. The first one would just be a survey asking about demographics. Then, I would issue a Custom Qualification to the participants who have the Type I'm looking for, invite them to take the main HIT, and hope for the best. 

I can't imagine that this is the most practical method though...

in the attached file you can find a raw data with qualification ids for premium qualifications

find corresponding one and use it in mturk_hit_settings in settings.py

(if you convert it to clean csv and upload here that would be helpful for community)

Thanks Philipp, this is perfect.

And attached is the converted csv file. (Edit: changed & to &)

Hi, 

I want to assign the premium qualification type 3ZA6VN4RCNNAUKDJ130LXNQBVABXQN (gender: female). Does this qualification take an integer value? In other words, should I write the following in the MTurk tab in oTree?

 {

      'QualificationTypeId': "3ZA6VN4RCNNAUKDJ130LXNQBVABXQN",

      'Comparator': "EqualTo",

      'IntegerValues': [1]

  }

In order to assign the qualification, simply enter  3ZA6VN4RCNNAUKDJ130LXNQBVABXQN   in the 'grant_qualification_id' field in oTree Studio.

Hi Chris, thank you for the quick reply. I do not want to assign this qualification. 3ZA6VN4RCNNAUKDJ130LXNQBVABXQN is one of the premium qualifications of MTurk (specifically "gender is female" and it's a Boolean variable). I want only female MTurkers to see this HIT. I'm not sure how to add this qualification requirement since it does not have an integer value.

See here: https://docs.aws.amazon.com/AWSMechTurk/latest/AWSMturkAPI/ApiReference_QualificationRequirementDataStructureArticle.html#ApiReference_QualificationRequirementDataStructureArticle-elements

I guess you want something like:

 {

      'QualificationTypeId': "3ZA6VN4RCNNAUKDJ130LXNQBVABXQN",

      'Comparator': "Exists"

  }

Wonderful, thank you!

Hi, I want to add the solution here for future if anyone else runs into the same problem.

Apparently the following does not work; as this qualification exists for everyone: it's a boolean variable that takes the value True or False. So exists comparator doesn't work.

{

      'QualificationTypeId': "3ZA6VN4RCNNAUKDJ130LXNQBVABXQN",

      'Comparator': "Exists"

  }

Instead, the code should be:

 {

      'QualificationTypeId': "3ZA6VN4RCNNAUKDJ130LXNQBVABXQN",

      'Comparator': "EqualTo",

      'IntegerValues': [1],

      'ActionsGuarded': "DiscoverPreviewAndAccept"

  }

Best,

Elif
