For the PSQI, three factors explained 61.3% of the variance. PCA resulted in two main orthogonal components: factor 1, which comprised a combination of scores for pain severity, pain interference and global scores of PCS, and PSQI; and factor 2, which comprised one measure of the SCL\u201090R. Factors 1 (46.5%) and 2 (20.0%) explained 66.5% of the total variance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The findings of this study revealed that five measures can be primarily categorised into two latent constructs of the psychological (affective) and pain\u2010related (sensory\u2010cognitive) dimensions.
