Store everything as embedded data!

[nik0lai]

Everything but Qualtrics text codes can be stored as embedded data variables. Therefore, to reduce the number of blocks, each item (problem context X presentation format X ppv prob + pictorials) are going to be stored as embedded data variables. Then, one question for each response type is created and from within the correct embedded data variable is called. To assign embedded data variables to each subject all of them go to a randomizer.

Embedded data (ED) fields do not take ":"! Items are imported as ED fields. One file per each condition (6 pres_format x 2 prob_context x 2 ppv_prob x 2 followUp_risk ) is created. A total of 48 txt files are to be created. Each text file must contain the following ED fields:

• presentation format field

• 01 problem context field

• 02 problem context field

• 01 ppv prob field

• 02 ppv prob field

• 01 followup risk

• 02 followup risk

• 01 prevalence field

• 01 item field

• 02 prevalence field

• 02 item field

Does follow up riks (high: 10%, low: 1%) correspond to ppv prob (high, low)? No, each follow-up risk with each possible condition. Full combination. It is necessary to add follow-up custom fields as embedded data.
