In analysis, the following methods were used: Cronbach's alpha, Item Response Theory (IRT), polychoric, Pearson and polyserial correlation, <jats:italic>t<\/jats:italic>-test, and Linear regression.<\/jats:p><\/jats:sec><jats:sec id=\"S1478951522001055_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>The internal consistency was high for all domains of the WHOQOL-BREF (Cronbach's <jats:italic>\u03b1<\/jats:italic> \u2265 0.731). Similarly, with the exception of three items, the WHOQOL-BREF items has large discrimination parameters suggesting that they have a high ability in differentiating subjects. On SCL-90, the three dimensions with the highest scores were Depression, Somatization, and Anxiety. The overall score for psychological distress, the Global Severity Index (GSI), showed significant negative association with all the WHOQOL-BREF factor scores (Physical Health: <jats:italic>B<\/jats:italic> = \u22121.488, <jats:italic>p<\/jats:italic> &lt; 0.001, Psychological Health: <jats:italic>B<\/jats:italic> = \u22121.688, <jats:italic>p<\/jats:italic> &lt; 0.001, Social Relationships: <jats:italic>B<\/jats:italic> = \u22120.910, <jats:italic>p<\/jats:italic> &lt; 0.001, Environment: <jats:italic>B<\/jats:italic> = \u22121.064, <jats:italic>p<\/jats:italic> &lt; 0.001).

The level of psychological distress can be considered a determinant of QoL in patients with advanced cancer and pain, independently of pain intensity or other clinical characteristics. In cancer, the disease process can activate multiple physiological and psychological mechanisms that lead to a wide range of symptoms of psychological distress. To improve their QoL, psychological intervention focused on the identification and alleviation of psychological distress in patients with advanced cancer, and help in finding meaning in their experience, should be
