Pain Sensitivity Questionnaire: A valid supplement to experimental pain testing

A study published in 'The Journal of Pain' explained that averaging across the 10-item set, the PSQ-short score depicted a structurally robust, gender-consistent and practical estimate for general pain sensitivity.

For experimental pain analysis, self-reported Pain Sensitivity Questionnaire (PSQ) proves to be a valid supplement. But, the latent constructs investigating the originally proposed one general score (PSQ-total) and two sub-scores (PSQ-moderate, PSQ-minor) have not been consistently examined in population-based studies or between genders before.
From single construct hypothesized by expert knowledge or alternative constructs upon empirical evidence, PSQ structures were explored and established among 4,820 participants between the age group18-93 years of the Cooperative Health Research In South Tyrol (CHRIS). 

Roberto Melotti et al. used the exploratory factor analysis to recognize 3 alternative sets of PSQ imagined painful situations which comprised of 14, 10 and 9 items; it exhibited simple structures of the rotated factor loadings of direct interpretation. 

In confirmatory analysis (CFA) of one latent factor, the 10-item set yielded acceptable goodness-of-fit overall, improved fit than the alternative sets and consistent structural features between genders. Among two latent constructs, distinct analyses based on 14- and 9-item sets showed considerable correlations. One first-order general factor explained large part of the variances of two second-order factors as described in the higher-order CFA with each set. The factorial layout of the PSQ was described in one dominant construct consistently.
