Under Tools in the Workplace windows there is a submenu SPSS with which SPSS
syntax and data files can be made.
Two choices are avaiable in a box case=subject files, and
case=subject x assessment files.
In the case=subject file each subject is a case and the assessments are 'spread'
horizontally, i.e. within the case. In the case=subject x assessment
file each subject has as many cases as there are assessments and the assessments
are 'spread' vertically. You can use the one that is most convenient
for your purpose.
Assessments made on a unscheduled base, e.g. Study medication (stm), concurrent medication (ccm) on assessment number -1 are exported to spss for each instrument seperately. These file are named after the instruments (see naming conventions). These will only be made if 'case=subject' is chosen.
Individual assessments and instruments can be chosen or all assessments and instruments. The selection has to be Saved and afterwards Run to get the files.
SPSShhmm.sps: SPSS syntax file
SPSShhmm.dat: data file to be read by SPSShhmm.sps
When you run the syntaxfile the resulting file will be a spss sytem file: SPSShhmm.sav
xxx.sps: SPSS syntax file
xxx.dat: data file to be read by SPSShhmm.sps
When you run the syntaxfile the resulting file will be a spss sytem file: xxx.sav ( xxx: first three letters of instrument.)
vars are named: xxxiiiaa, where:
xxx: first three letters of instrument (see beginning of SPSShhmm.sps)
iii: itemnumber
aa : assessmentnumber (only for case=subject file, not for case=subject x assessment file).
subject subjectnumber
centre centre number
sid concatenation of subjectnumber and centre number
For several instruments, scale values have been defined as compute statements. These can be found at the end of the *.sps files, also the labels for the computed values can be found there.
