The questionnaire was completed at baseline and three days later. Together with the MMSE, the patients also completed the EORTC QLQ\u2010C30 Cognitive functioning scale, while researchers recorded data on demographic characteristics, disease status and treatment regimen.<\/jats:p><jats:p><jats:italic>Results<\/jats:italic>: MMSE had overall Cronbach \u03b1 0.890. Validity as performed using known\u2010group analysis showed good results. MMSE discriminated well between subgroups of patients differing in disease severity as defined by ECOG performance status. Comparison between the MMSE and the EORTC Cognitive functioning scale was statistically significant (<jats:italic>p<\/jats:italic>&lt;0.05).<\/jats:p><jats:p><jats:italic>Conclusion<\/jats:italic>: These psychometric properties of the Greek version of the MMSE confirm it as a valid and reliable measure when administered to patients with advanced cancer.
