In this study our aim was to examine the validity and reliability of the Turkish version of QLQ-C15-PAL for the palliative care patients with advanced cancer. Research question: Is Turk- QLQ-C15-PAL a reliable and valid tool for advanced cancer home care patients? Method: This methodological study is completed with a population of 147 Medical Oncology outpatient clinic patients of Marmara University Pendik Research and Training Hospital who are referred to Home Care Unit. The test-retest was performed to 16 of the patients in a 10-14 days interval. QLQ-C15-PAL consists of 14 questions about physical functions, emotional function and symptoms with a Likert scale of 4: ‘not at all’, ‘a little’, ‘quite a bit’, ‘very much’. The last one is a general quality of life question with a visual scale from 1 (very poor) to 7 (excellent). The questions about the sociodemographic characteristics and daily activities of life were performed face to face by the researcher. Results: The test-retest total scores were evaluated with Wilcoxon test (p>0,05). CronbachĮ=0,88 demonstrates the internal consistency of the questionnaire. Other than nausea, Pearson coefficient of the symptoms correlated with each other significantly in a range of low (r=0,18) to high degree (r=0,67). Confirmatory factor analysis was computed with Keiser-Meyer Olkin and Barlett test and Turk- QLQ-C15-PAL was found to have 4 subgroups and the internal consistency of these subgroups varied between r=0,49-0,89. The quality of life scores were higher with still working and independent patients in daily life activities (p<0,05) than the retired and dependent ones. Conclusions: The Turkish version of EORTC-QLQ-C15-PAL is a valid and reliable instrument to evaluate the quality of lives of Turkish palliative care cancer patients.
