Abstract

Aim: One of the most extensively used questionnaires in studies and clinical trials is the Foot Function Index (FFI). The aim of our study was to evaluate the reliability and the validity of the FFI in Turkish patients with calcaneal heel spur.

Methods: A cross-sectional study was performed in 20014-2015 in Ankara, Turkey with 146 patients with calcaneal heel spur. Statistical analyses were performed using the SPSS software version 20.0. Intra-class correlation coefficients (ICC) and Cronbach alpha coefficients were used to determine test-retest reliability and internal consistency of FFI. Construct validity was tested by Pearson correlation coefficient approach comparing the correlation of the Visual Analogue Pain Scale (VAS-pain), foot and ankle outcome score (FAOS) and The Short Form-36 (SF-36) questionnaire with FFI.

Results: A hundred and forty six patients (125 women, 21 men) were enrolled in the study. The mean age of the patients were 46,4±10,3 years. The random ICC for the total FFI and three subscales ranged from 0.74 to 0.99. The Cronbach’s alpha coefficient ranged from 0.78 to 0.83. In terms of validity, there was a significant correlation between the Turkish version of FFI, VAS, some of the sub-scales of FAOS and SF-36 scores (p<0.05).

Conclusion: The Turkish version of FFI was valid and reliable to assess the foot disease in patients with heel spur. It can be used for both in clinic and research studies in the assessment of pain, disability and limitation of the function of the foot.

Topuk dikeni olan hastalarda ayak fonksiyon indeksinin Türkçe geçerlik ve güvenirlik çalışması

Year 2018, , 118 - 122, 01.05.2018

Abstract

Amaç: Ayak Fonksiyon İndeksi (Foot Function Index: FFI) klinik uygulamalar ve araştırmalarda yaygın kullanılan ölçeklerden biridir. Bu araştırmanın amacı FFI’in, topuk dikeni tanısı olan hastalarda Türkçe geçerlik ve güvenirliğini çalışmaktır. 

Yöntemler: Verilerin İstatistiksel analizleri SPSS 20.0 paket programı kullanılarak analiz edilmiştir. Test-tekrar test güvenirliğini ve FFI iç tutarlılığını belirlemek için sınıf içi korelasyon katsayıları (ICC) ve Cronbach alfa katsayıları kullanılmıştır. Yapı geçerliği, vizüel analog skalası (VAS-ağrı), ayak ve ayak bileği sonuç skoru (FAOS) ve Kısa Form-36 (SF-36) ile FFI arasındaki ilişki Pearson korelasyon katsayısı ile test edilmiştir.

Bulgular: Çalışmamıza 125’i kadın 21’i erkek olmak üzere 146 hasta dahil edilmiştir. Hastaların yaş ortalaması 46,4± 10,3 yıl idi. Toplam FFI ve üç alt ölçek olan VAS, FAOS ve 

SF-36 için rastgele ICC, 0,74 ile 0,99 arasında bulunmuştur. Cronbach'ın alfa güvenirlik katsayısı en düşük 0,78 ve en büyük 0,83 olarak hesaplanmıştır. Geçerlik açısından ise FFI ile VAS, FAOS ve SF-36 puanlarının bazı alt ölçekleri arasında anlamlı ilişki bulunmuştur (p<0.05).

Sonuç: Bu çalışmada, topuk dikeni tanısı olan hastaları değerlendirmek için kullandığımız FFI'nın Türkçe versiyonun geçerli ve güvenilir olduğu gösterilmiştir. Bu ölçeğin, klinik ve araştırmalarda ayak ağrıları, yetersizlik ve ayak fonksiyonlarını değerlendirmek için hastalara uygulanabileceğini düşünmekteyiz.
