Construct validity and reliability of the WHOQOL-Bref, its responsiveness compared with that of the SF-36, and the correlations between the 2 scales were studied.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The WHOQOL-Bref was found to be valid (p &lt; 0.001, Cuzick test for trend between the physical domain of the WHOQOL-Bref and Nurick grade) and reliable (Cronbach \u03b1 &gt; 0.7). It had smaller floor and ceiling effects (ranges 1.4\u20137.1% and 0\u20137.1%, respectively) than the SF-36 (ranges 2.9\u201371.4% and 0\u201314.1%, respectively). There was significant postoperative improvement in patient scores on all the SF-36 scales (p &lt; 0.001) and the physical, psychological, and environment domains of the WHOQOL-Bref (p &lt; 0.001). The SF-36 scales were more responsive to change (relative efficiency range 0.24\u20131) than the WHOQOL-Bref domains (relative efficiency range 0.002\u20130.73). Among scales measuring similar concepts, only the physical functioning and bodily pain scales of the SF-36 had a moderate correlation (r = 0.57 and 0.53, respectively; p &lt; 0.001) with the physical domain of WHOQOL-Bref. Many of the scales of these 2 QOL instruments unexpectedly had a fair correlation with one another (r range = 0.2\u20130.4).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The WHOQOL-Bref, like the SF-36, is valid and reliable in assessing outcome in patients with CSM. It measures impairment in CSM in a more uniform manner than the SF-36, but its domains are less responsive to postoperative changes. Because the WHOQOL-Bref measures different constructs and has additive value, it should be used along with the SF-36 for QOL assessment in patients with CSM.<\/jats:p>\n
