Quality of Life Assessment in Southwest Oncology Group Clinical Trials: Translating and Validating a Spanish Questionnaire

  • C. M. Moinpour


This paper describes the approach used by the Southwest Oncology Group (SWOG) to assess quality of life in cancer clinical trials. SWOG is a cooperative group in the United States that conducts clinical trials to evaluate new cancer treatments. Quality of life is assessed in selected trials, particularly those in which treatment aims are expected to differ minimally with respect to traditional endpoints and palliative objectives are of concern. SWOG’s assessment approach is component-based and includes both generic and cancer-specific quality of life scales; the Medical Outcomes Study Short Form scales and the Symptom Distress Scale are the main standardized instruments included in the SWOG Quality of Life Questionnaire. Currently there is only an English version of SWOG’s questionnaire. Hispanic Americans are the second largest minority group in the United States. Many Hispanics prefer interviews to be conducted in Spanish and many who can speak English do not necessarily prefer using English for reading or writing activities. Therefore, to avoid continuing to exclude Hispanic patients unable to complete questionnaires in English, we will be translating the SWOG Quality of Life Questionnaire into Spanish and conducting necessary validation research. A summary of the research plan is provided.
