Background: Cancer affects the quality of life of the patient. There is a lack of instrument in Brazilian Portuguese that could identify the demands, concerns and needs of cancer patients.

Purpose: To culturally adapt and to evaluate the psychometric properties of the Demands of Illness Inventory (DOI) in cancer patients in Brazilian Portuguese language.

Methods: Methodological study; develop in two stages, cultural adaptation and psychometric evaluation of the instrument. To analyze the properties of the instrument it has been evaluated in 658 cancer patients in chemotherapy treatment of a large public hospital in São Paulo, Brazil. The Content Validity Index (CVI) and the Kappa coefficient have been used. The Exploratory Factor Analysis (EFA) have been performed and the correlation analysis has been performed with the Distress Thermometer instrument. The reliability has been tested by Cronbach’s alpha and McDonald’s omega coefficients.

Results: All the stages of cultural adaptation have been satisfactorily confirmed. The CVI and Kappa have presented values higher than 0.75 and 0.72, respectively. The Kaiser-Meyer-Olkin measurement have been obtained 0.930 and Bartlett’s χ2 of Bartlett 2414.1, p≤0.001. The EFA account for 46.5% of the total variance. For Cronbach’s alpha was 0.961 and McDonald’s omega was 0.952.

Conclusions: The DOI in the patient with cancer has culturally adapted in Brazilian context, presenting evidence of content validity, construct and reliability
