 the rank order values and found them to be in the .91 to .94 range with

 a correlation of .95 for all four scales (see Table 3-4).

The categories are S, sensory; A, affective; E, evaluative; M,
miscellaneous; T, total, based on n = 248 (Melzack, 1975).



The number of words chosen total scale has four subscales: (a) the

number of words chosen sensing (NWCS), (b) the number of words chosen

affective (NWCA), (c) the number of words chosen evaluative (NWCE), and

(d) the number of words chosen miscellaneous (NWCM). The pain rating

index total scale also has four subscales: (a) the pain rating index

sensory (PRIS), (b) the pain rating index affective (PRIA), (c) the pain

rating index evaluative (PRIE), and (d) the pain rating index

miscellaneous (PRIM).

 Correlations between the number of words chosen (NWC) and the pain

rating index (PRIT) was r = .97 for the scale (S) value and r = .89 for

the rank order (R) value.
