Table 5.

T-values comparing correlation coefficients between SF-MPQ-2 Affective scale versus SF-MPQ-2 Continuous, Intermittent, and Neuropathic scales with other pain and psychiatric measures.

SF-MPQ-2 Scale Comparisons
Affective Versus Continuous Affective Versus Intermittent Affective Versus Neuropathic

p < 0.05.

Note: Critical value for Hotelling-Williams t-tests with 183 df = 1.97 for two-tailed α of 0.05.

Negative t-values indicate a lower affective scale correlation relative to the SF-MPQ-2 scale correlation to which it is compared.
