PennController for IBEX Forums Support Problem with reading data Reply To: Problem with reading data


The “Item” column reports the item number according to Ibex. The other number corresponds to the PennController trial’s index: since PennController trials do not necessarily constitute the entirety of the study’s items (and certainly, in your study, you have non-PennController items, for example the one labeled “intro” does not contain a PennController trial but instead contains a single Message controller) the two number do not necessarily align. The example you mention means that the 40th item in your study corresponded to the 35th PennController trial, and that there likely are at least 5 items that are not PennController trials (I say “likely” because there are other potential sources of mismatch between Ibex’s item numbers and PennController’s trial numbers, eg. one could create some PennController trials first in a certain order and pass them as Ibex items later in a different order)
