The files uploaded in the "Item tables" folder below are excel files containing old variable names, new variable names, the text of each item, and a description of the response generated by the participant (e.g., "Likert scale from 1 (*strongly disagree*) to 15 (*strongly disagree*)", "time in hh:mm:ss").
I suggest that you start with the item tables on the right hand side of this page (see Components -> Item tables). These tables may be slightly easier to manage, because there are tabs for each section of the questionnaires.
