Introduction: The World Health Organization (WHO) defines cancer as a generic terminology for a vast group of diseases that can affect any part of the body. This pathology is the second leading cause of death in the world, with one in six deaths related to the disease. Therefore, the care given to these patients requires early identification, aiming, above all, at the relief of suffering and, in some cases, the remission of the disease. In view of the findings in the literature, several strategies have been used to identify the suffering of cancer patients, in this sense the Patient Dignity Inventory (PDI) instrument was produced. This inventory aims to provide a measure of dignity-related suffering and serves as a screening tool to assess a wide range of reported issues that influence a sense of dignity. Objective: To carry out a cross-cultural adaptation of the Patient Dignity Inventory (PDI) instrument from English to Brazilian Portuguese. Method: This is a quantitative, transversal and analytical methodological design research. Conceptual, item, semantic, operational and measurement equivalence were performed between the original and the adapted instrument. In addition, the psychometric properties of the instrument in the new contextual reality were verified. Results: The research was carried out with 125 adult patients, mostly women (n=98; 78.4%), over 45 years old (54.4%), at the University Hospital Onofre Lopes (29.6%) and at the League Against Cancer (70.4%)). Information was collected through the sociodemographic questionnaire, the Patient Dignity Inventory – PDI and the WHOQOL-Bref quality of life instrument. Descriptive and comparative analyzes were performed for all variables, with a significance level of 5%. To verify the aspects of construct validity, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were carried out, presenting a correlation matrix of 5 factors, in relation to the reliability of the general score of the inventory, it was analyzed from the Cronbach's Alpha, demonstrating 0.93 result. Regarding the factor distribution, the PDI behaved satisfactorily, presenting 5 factors as well as the original instrument, but with items occupying different dimensions. Criterion and convergent validities were also verified through Pearson and MANOVA correlations, respectively. In the analysis process, it was also identified that through the verification of conceptual, item and semantic equivalences, a synthesis version of the PDI was produced. Regarding the operational and measurement equivalences, a final synthesis version was prepared and the version that was duly validated for the Brazilian context. Conclusion: The instrument presented satisfactory values of internal consistency, as well as criterion and construct validity, fulfilling the objective that was proposed. In this way, it is configured as a screening instrument for aspects that refer to the dignity of cancer patients in an outpatient and hospital environment in the reality of Brazil.
