Amaç: Bu araştırmanın amacı bel ağrısı olan hastalarda Fonksiyonel Bel Ağrısı Skalası’nın (FBAS) Türkçe uyarlamasını
yapmak, geçerlik ve güvenirliğini araştırmaktı.

Yöntem: Çalışmaya Türkçe okuma-yazma bilen, non-spesifik bel ağrısı tanısı alan 18-79 yaş aralığında 120 birey dahil edildi.
Tüm bireylere FBAS, Vizüel Analog Skala (VAS), Roland Morris Disabilite Anketi (RMDA), Oswestry Özürlülük İndeksi (OÖİ) ve
KF-36 Yaşam Kalitesi Anketi (KF-36) uygulandı. Güvenirlik için test-tekrar test güvenirliği ve iç tutarlılık analizleri yapıldı. Yapı
geçerliği açımlayıcı ve doğrulayıcı faktör analizi ile,FBAS kriter geçerliği RMDA, OÖİ ve KF-36 fiziksel fonksiyon alt grubu
korelasyon analiziyle incelendi.

Bulgular: Test-tekrar test korelasyon katsayısı r=0.87; p<0.01, Cronbach alfa 0.899, madde toplam puan korelasyon
katsayıları 0.484 ile 0.710 idi. Açımlayıcı faktör analizinde skalanın tek faktörlü yapıda olduğu ve varyansın %48.172'sini
açıkladığı görüldü. Doğrulayıcı faktör analizi ile skalanın tek faktörlü model yapısı doğrulandı. FBAS; RMDA (r=-0.693,
p<0.001), OÖİ (r=-0.794, p<0.001) ve KF-36’nın fiziksel fonksiyon alt grubuyla (r=0.607, p<0.001) orta düzey korelasyon
gösterdiği bulundu.

Sonuç: FBAS'ın Türkçe versiyonu bel ağrısı olan hastalarda fonksiyon kaybını ölçmede kullanılabilecek geçerli ve güvenilir bir
ölçüm aracı olduğu görüldü.

Turkish version of the Back Pain Functional Scale: validity and reliability study

Öz

Purpose: The purpose of this study was to investigate the Turkish adaptation, validity and reliability of the Functional Back
Pain Scale (FBAS) in patients with back pain.

Methods: One-hundred and twenty subjects were included in the study, who were able to read and write Turkish, who were
diagnosed as non-specific back pain and were between 18 and 79 years of age. FBAS, Visual Analog Scale (VAS), Roland
Morris Disability Questionnaire (RMDA), Oswestry Disability Index (OOI) and SF-36 Quality of Life Questionnaire (SF-36) were
performed to all patients. Test retest reliability and internal consistency analyzes were conducted for reliability. The construct
validity was examined by exploratory and confirmatory factor analysis while the criterion validity of FBAS was examined by
correlation analysis between RMDA, OOI and SF-36 sub-group of physical function.

Results: Test-retest correlation coefficient was r=0.87; p<0.01, Cronbach’s alpha 0.899, and total item correlation
coefficients were between 0.484 and 0.710. In explanatory factor analysis, the scale was found to be a one-factor structure
and explained 48.172% of the variance. The one-factor model of the scale was confirmed by confirmatory factor analysis.
FBAS showed moderate correlation with RMDA (r=-0.693, p<0.001), OÖI (r=-0.794, p<0.001) and physical function
subgroup of SF-36 (r=0.607, p<0.001).

Conclusion: The Turkish version of FBAS is a valid and reliable measurement tool that can be used tomeasure loss of function
in patients with back pain.
