Hey there,
how do I add likert values to the summary data file?
The preliminary study (attached) consists of 12 video clips. After each clip follows a new page with a likert scale (rating of the video). Im only interested in these values (-3 to 3).
The combination of one video and one rating forms one block. Each rating is named differently.
I`ve already used the summary data command:
<summarydata>
/ columns=[script.subjectid, script.startdate, script.starttime]
/ file="Videoratings_summary.iqdat"
</summarydata>
and tried different new columns: likert.trialname, values.trialname, responses.trialname...
Do I need to use the <value> command and define the values I´m interested in? Already tried it, but it did not work.
<values>
/name of the trial (e.g.:m_s3) = 0
</values>
Thank you for your help!

A summary data file is supposed to capture a _single_ line of summary data. If you wanted to have a column for each likert element you run, you ought to specify:
<summarydata>
/ columns = [..., likert.f_h1.response, likert.f_h2.response, likert.f_h3.response, ...]
...
</summarydata>
and so forth. This will, of course, only make sense if each likert is only ever run a single time.
You'll find the data captured in the regular _raw_ data file as well. The trialcode column hold's the likert's name, the response column holds the respective response.
