Giriş ve Amaç: Son 20 yılda geliştirilen kansere özgü yaşam kalitesi (QOL) anketlerinin çoğu, referans önlemler olarak düşünülebilir. Kronik Hastalık Tedavisinin İşlevsel Değerlendirmesi (FACIT) sistemi, temelli ve genel sağlıkla ilgili yaşam kalitesi ölçümleridir. Bu çalışmanın amacı, Functional Assessment of Cancer Therapy General (FACT-G)'nin Türk kanser hastaları için güvenilirliğini ve geçerliliğini test etmektir.
Gereç ve Yöntemler: Bu araştırma metodolojik tiptedir. Veriler, sosyodemografik ve FACT-G anketi kullanılarak elde edildi. Örneklem 148 kanser hastasını içermektedir. Veriler, SPSS paket programı kullanılarak tanımlayıcı istatistikler ve ölçeklerin güvenirliğini saptamada, cronbach alfa katsayısı ve madde toplam korelasyon katsayısı (Pearson korelasyon) ile değerlendirildi. Enstrümanın geçerliliği için; açıklayıcı ve doğrulayıcı faktör analizi kullanıldı.
Bulgular: Kanser Tedavisinin İşlevsel Değerlendirmesi Ölçeği toplam puanı 60.71±14.42 iken, fiziksel, sosyal/ aile, duygusal ve fonksiyonel iyilik alt ölçeklerinin puan ortalamaları ise sırasıyla; 15.83±5.48, 13.91±4.90, 13.45±5.03, 17.51±5.04 olarak bulundu. Ölçeğin iç tutarlılığını belirlemek için kullanılan cronbach alfa katsayısı toplam ölçek için 0.88 olarak, alt ölçeklerde ise 0.70 ile 0.79 arasında bulundu. FACT-G ve dört alt boyutunun puanları arasında istatistiksel olarak pozitif yönde korelasyon ve anlamlı bir ilişki olduğu saptandı (p=0.001).
Sonuç: Bu araştırmada FACT-G ölçeğinin psikometrik özelliklerinin değerlendirmesi sonucunda, ölçeğin Türkiye’deki kanser tanılı hastalarda kullanımı için geçerli ve güvenilir bir araç olduğu belirlendi.

Objective: Many of the cancer-specific quality of life (QOL) questionnaires improved over the last 20 years, can be contemplated as reference measures. The Functional Assessment of Chronic Illness Therapy (FACIT) system is an based and generic health-related quality of life measures. The aim of this study was conducted to test the reliability and construct validity of the Functional Assessment of Cancer Therapy General (FACT-G) for Turkish cancer patients.
Material and Methods: This research is a methodological study. The data were obtained by using the sociodemographic and the FACT-G questionnaire. The sample comprised 148 cancer pa¬tients. Data were analysed by using the SPSS package program, descriptive statistics and to assess the reliability of the scales, cronbach alpha coefficient, item total score analysis, and, item total correlation coefficient (Pearson's correlation). For the construct validity of the instrument; exploratory factor analysis and confirmatory factor analysis were used.
Results: The mean total score of FACT-G was 60.71±14.42, and for the physical, social/ family, emotional and functional well-being subscales 15.83±5.48, 13.91±4.90, 13.45±5.03 and 17.51± 5.04, respectively. The alpha coefficient was 0.88 for the global scale of the FACT-G questionnaire and ranged from 0.70 to 0.79 across subscales. A statistically significant positive correlation was found between FACT-G and test-retest scores of the four sub-dimensions (p=0.001).
Conclusion: In this study, as a result of evaluating the psychometric properties of the FACT-G scale, the scale is a valid and reliable tool for use in Turkish patients with cancer.
