Objective To assess the test-retest reliability of the Memorial Symptom Assessment Scale translated and culturally adapted into Brazilian Portuguese.Methods The scale was applied in an interview format for 190 patients with various cancers type hospitalized in clinical and surgical sectors of the Instituto Nacional de Câncer José de Alencar Gomes da Silva and reapplied in 58 patients. Data from the test-retest were double typed into a Microsoft Excel spreadsheet and analyzed by the weighted Kappa.Results The reliability of the scale was satisfactory in test-retest. The weighted Kappa values obtained for each scale item had to be adequate, the largest item was 0.96 and the lowest was 0.69. The Kappa subscale was also evaluated and values were 0.84 for high frequency physic symptoms, 0.81 for low frequency physical symptoms, 0.81 for psychological symptoms, and 0.78 for Global Distress Index.Conclusion High level of reliability estimated suggests that the process of measurement of Memorial Symptom Assessment Scale aspects was adequate.
Objective: to describe the process of semantic equivalence, the first stage in the validation of the EORTC QLQ-ELD14 instrument for Brazilian Portuguese. Method: Direct and independent translations of the instrument into Portuguese were carried out and validated by a meeting of experts to generate a synthesis version. The version chosen was submitted to reverse translations into English, and the form was pre-tested with patients. At the conclusion of the process, a summary version was presented. The pre-test and the final version of the instrument were applied to a total of 28 patients at a high complexity oncology treatment center. Result: after completion of the first round of pretesting, some adjustments for the next phase of the study were necessary by the expert committee. After these adjustments, in the second phase of pre-testing, the instrument was wellaccepted by the population. Conclusion: the Portuguese summary version of the EORTC QLQ-ELD14 instrument for assessing the quality of life of elderly cancer patients is ready to be submitted to the next stages of the evaluation of its psychometric properties.
