Rating (or partial credit) scale output is easier to understand when the categories are shown with their substantive meanings. Use CFILE= to label categories using their scored values, i.e., after rescoring. Use CLFILE= to label categories using their original codes, i.e., before any rescoring.
Labels for categories, after they have been scored, can be specified using CFILE= and a file name, or CFILE=* and placing the labels in the control file. Each category number is listed (one per line), followed by its descriptive label. If the observations have been rescored (NEWSCORE=) or keyed (KEYn=), then use the recoded category value in the CFILE= specification. When there are different category labels for different ISGROUPS= of items, specify an example item from the grouping, followed immediately by "+" and the category number. Blanks or commas can be used a separators between category numbers and labels.
CFILE= file name

file containing details

CFILE = *

CFILE = ?

Example 1: Identify the three LFS categories, 0=Dislike, 1=Don't know, 2=Like.
CODES=012
CFILE=*
0 Dislike
1 Don't know
2 Like
*
The labels are shown in Table 3.2 as:
-------------------------------------------------------
CATEGORY OBSERVED AVGE INFIT OUTFIT STRUCTURE
LABEL COUNT MEASURE MNSQ MNSQ MEASURE
-------------------------------------------------------
0 378 -.87 1.08 1.19 NONE Dislike
1 620 .13 .85 .69 -.85 Don't know
2 852 2.23 1.00 1.46 .85 Like
-------------------------------------------------------
Example 2: Items 1-10 (Grouping 1) are "Strong Disagree, Disagree, Agree, Strongly Agree". Items 11-20 (Grouping 2) are "Never, Sometimes, Often, Always".
NI=20
CODES=1234
ISGROUPS=11111111112222222222
CFILE=*
7+1 Strongly Disagree ; We could use any item number in Grouping 1, i.e., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
7+2 Disagree ; item 7 has been chosen
7+3 Agree
7+4 Strong Agree
13+1 Never ; We could use any item number in Grouping 2, i.e., 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
13+2 Sometimes ; item 13 has been chosen
13+3 Often
13+4 Always
*
Example 3: To enter CFILE= information on the DOS Prompt or Extra Specifications lines, using commas instead of blanks as separators:
C:>Winsteps SF.TXT SFO.TXT CFILE=* 1,Dislike 2,Don't-know 3,Like *
Example 4: Some items have one rating scale definition, but most items have another rating scale definition. But each item is calibrated with its own structure: ISGROUPS=0
NI=20
CODES=1234
ISGROUPS=0
CFILE=*
1 Strongly Disagree This scale is used by most items
2 Disagree
3 Agree
4 Strong Agree
16+1 Never 16 is one item using the other scale
16+2 Sometimes
16+3 Often
16+4 Always
17+1 Never 17 is another item using the other scale
17+2 Sometimes
17+3 Often
17+4 Always
.... for all the other items using the other scale
*
Example 5: Several categories are collapsed into one category. The original codes are A-H. After rescoring there is only a dichotomy: 0, 1.
NI=30
CODES =ABCDEFGH
NEWSCORE=00011110
CFILE=*
0 Fail Specify the categories as recoded
1 Pass
