RESUMO
ABSTRACT 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.
RESUMO Objetivo Avaliar a confiabilidade teste-reteste da versão traduzida e adaptada culturalmente para o português do Brasil do Memorial Symptom Assessment Scale. Métodos A escala foi aplicada em forma de entrevista em 190 pacientes com diversos tipos de câncer internados nos setores clínicos e cirúrgicos do Instituto Nacional de Câncer José de Alencar Gomes da Silva e reaplicada em 58 pacientes. Os dados dos testes-retestes foram inseridos num banco de dados por dupla digitação independente em Excel e analisados pelo Kappa ponderado. Resultados A confiabilidade da escala mostrou-se satisfatória nos testes-retestes. Os valores do Kappa ponderado obtidos para cada item da escala apresentaram-se adequados, sendo o maior item de 0,96 e o menor de 0,69. Também se avaliou o Kappa das subescalas, sendo de 0,84 para sintomas físicos de alta frequência, de 0,81 para sintomas físicos de baixa frequência, de 0,81 também para sintomas psicológicos, e de 0,78 para Índice Geral de Sofrimento. Conclusão Altos níveis de confiabilidade estimados permitem concluir que o processo de aferição dos itens do Memorial Symptom Assessment Scale foi adequado.

Background: Spiritual issues are an important dimension of health care, but seldom addressed by professionals. Thus, a scale that assesses the presence and intensity of seven spiritual symptoms was developed. Aim: To validate the instrument in palliative care settings. Material and Methods: The spiritual symptoms scale was applied to 103 patients, aged 59 ± 17 years (58% women), admitted to hospice care in two centers located in Santiago. The reproducibility of the scale was evaluated in 33 patients and its internal consistency and liability in 70. Results: The Fleiss Kappa to assess reproducibility was 0.82 and the analysis of variance had a p of 0.94. Cronbach alpha to assess internal consistency was 0.74. Conclusions: The scale renders similar results when applied by different evaluators and has a good liability. Therefore, it can be a reliable instrument to assess spiritual symptoms in palliative care settings. Further studies would be needed to verify its utility in other settings.
