ObjectiveDepression in palliative advanced cancer patients is common, but often goes unrecognized. One of the first steps toward improving detection is the development of tools that are valid in the specific language and setting in which they are to be used. The Brief Edinburgh Depression Scale (BEDS) is a sensitive case-finding tool for depression in advanced cancer patients that was developed in the United Kingdom. There are no validated instruments to identify depression in Mexican palliative patients. Our aim was to validate the Spanish-language version of the BEDS in Mexican population with advanced cancer.MethodWe conducted a cross-sectional study with outpatients from the palliative care unit at the Instituto Nacional de Cancerología in Mexico City. The Mexican BEDS was validated against a semistructured psychiatric clinical interview according to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, classification criteria for major depressive disorder. The interviewer was blind to the BEDS score at the time of the assessment.ResultSeventy subjects completed the scale and interview. Women represented 71.4% of the sample and median age of subjects was 56.5 years (range, 20-85 years). The prevalence of major depressive disorder according to the psychiatric interview was 20%. The most valid cutoff for defining a case of depression was a score ≥5 of 18 on the Mexican BEDS, which gave a sensitivity of 85.7% and specificity of 62.5%. The scale's Cronbach's alpha was 0.71.Significance Of ResultsMajor depressive disorder is frequent in Mexican palliative patients. The Spanish-language Mexican version of the BEDS is the first valid case-finding tool in advanced cancer patients in this setting.
