KANSER HASTALARINDA FACIT-DISPNEA SKALASININ TÜRKÇE VERSİYONUNUN PSİKOMETRİK ÖZELLİKLERİ

Abstract

Amaç: Bu çalışmada Kronik Hastalık Terapisinin Fonksiyonel Değerlendirmesi (FACIT)-Dispne Kısa Formu’nun Türkçe versiyonunun kanser hastalarında geçerliliğini ve güvenilirliğini araştırmak amaçlandı. Yöntem: Çalışmaya dispne şikayeti olan elli iki kanser hastası dahil edildi. FACIT-Dispne’nin geçerliliği ve güvenilirliği, açıklayıcı ve doğrulayıcı faktör analizleri, yapı geçerliliği, iç tutarlılık [Cronbach alfa (α)], test-tekrar test güvenilirliği [sınıf içi korelasyon katsayısı (ICC)], madde-toplam korelasyonları ve split-half testleri ile değerlendirildi. Yapı geçerliliği için FACIT-Dispne ile Doğu Kooperatif Onkoloji Grubu (ECOG), Performans Ölçeği, Medikal Araştırma Konseyi Dispne Ölçeği, Kanser Dispne Ölçeği ve EuroQol 5-Boyutlu 3-Seviyeli anket (EuroQoL-5D-3L) arasındaki korelasyonlar incelendi. Bulgular: Faktör Analizi sonuçları, FACIT-Dispne’nin tek faktörlü bir yapıya sahip olduğunu ve tüm maddelerin yüksek faktör yüklerine sahip olduğunu gösterdi. FACIT-Dispne ile ECOG, Medikal Araştırma Konseyi Dispne Ölçeği, Kanser Dispne Ölçeği ve EuroQoL-5D-3L arasında anlamlı korelasyonlar bulundu (p<0,05). FACIT-Dispne’nin Cronbach α’sı 0,973 ve ICC 0,85 olarak bulundu. FACIT-Dispne’deki maddelerin toplam madde korelasyonları 0,695 ile 0,948 arasında değişmekteydi. Split-half testinde, FACIT-Dispne’nin ilk bölümü için Cronbach α’sı 0,937 ve ikinci bölümü için 0,955 idi. Sonuç: FACIT-Dispne’nin Türkçe versiyonu, kanser hastalarında geçerli ve güvenilirdir ve araştırmacılar ve klinisyenler tarafından kullanılmaya uygundur.

PSYCHOMETRIC PROPERTIES OF THE TURKISH VERSION OF THE FACIT-DYSPNEA SCALE IN CANCER PATIENTS

Abstract

Purpose: This study aimed to investigate the validity and reliability of the Turkish version of the Functional Assessment of Chronic Illness Therapy (FACIT)-Dyspnea Short Form in patients with cancer. Methods: Fifty-two patients with cancer with complaint of dyspnea were included in the study. The validity and reliability of the FACIT-Dyspnea were evaluated via exploratory and confirmatory factor analyses, construct validity, internal consistency [Cronbach’s alpha (α)], test-retest reliability [intraclass correlation coefficient, (ICC)], item-total correlations and split-half tests. For construct validity, correlations between FACIT-Dyspnea and Eastern Cooperative Oncology Group (ECOG), Performance Scale, Medical Research Council Dyspnea Scale, Cancer Dyspnea Scale and EuroQol 5-Dimension 3-Level questionnaire (EuroQoL-5D-3L) were examined. Results: Factor Analyses results showed that the FACIT-Dyspnea has a unifactorial structure, with all items having high factor loadings. Significant correlations were found between the FACIT-Dyspnea and the ECOG, Medical Research Council Dyspnea Scale, Cancer Dyspnea Scale, and EuroQoL-5D-3L scores (p< 0.05). Cronbach’s α of the FACIT-Dyspnea was found to be 0.973 and ICC was 0.85. Item-total correlations for items in the FACIT-Dyspnea ranged from 0.695 to 0.948. In the split-half test, the Cronbach’s α for the first part of the FACIT-Dyspnea was 0.937 and for the second part was 0.955. Conclusion: The Turkish version of FACIT-Dyspnea is valid and reliable in patients with cancer and is suitable for use by researchers and clinicians.
