Abstract

Purpose: The Parkinson’s Disease Falls Questionnaire (PDF-Q) was developed to systematically assess fall history and associated factors in Parkinson’ Disease (PD). This study aimed to adapt the PDF-Q for the Turkish population. Material and Methods: A total of 51 individuals diagnosed with PD (aged 40–80) were included. The translation and cross-cultural adaptation of the questionnaire were conducted according to standard guidelines. The test-retest reliability of the Turkish PDF-Q was assessed with a 10-day interval. The Intraclass Correlation Coefficient (ICC) and Kappa statistics were used for analysis. Results: Questions assessing the fall experiences in the past 12 months (κ=0.564) and near-falls (κ=0.551) demonstrated moderate agreement, while questions regarding the location of indoor falls (κ=0.848) and near-falls (κ=0.801) showed strong agreement. The ICC values for the number of indoor (0.957) and outdoor (0.939) falls indicated strong agreement, whereas the ICC values for the number of indoor (0.987) and outdoor (0.993) near-falls also demonstrated strong agreement. Discussion: The Turkish adaptation of the PDF-Q demonstrated good test-retest reliability and currently stands as the only available validated tool for assessing fall history and circumstances in individuals with PD in Turkish. Although its reliability against other tools has not yet been tested, it can still be effectively used in clinical and research settings to assess falling and inform preventive strategies.

Parkinson Hastalığında Düşmelerin Değerlendirilmesi: Parkinson Hastalığı Düşme Anketinin Türkçeye Uyarlanması

Abstract

Amaç: Parkinson Hastalığı Düşme Anketi (PDF-Q), Parkinson Hastalığında (PD) düşme geçmişini ve ilişkili faktörleri sistematik olarak değerlendirmek için geliştirilmiştir. Bu çalışmanın amacı PDF-Q'yu Türk toplumuna uyarlamaktır. Gereç ve Yöntem: PD tanısı konmuş toplam 51 birey (yaşları 40-80 arasında) çalışmaya dahil edildi. Anketin çevirisi ve kültürler arası uyarlaması standart kılavuzlara göre yapıldı. Türkçe PDF-Q'nun test-tekrar test güvenilirliği 10 günlük bir aralıkla değerlendirildi. Analiz için Sınıf İçi Korelasyon Katsayısı (ICC) ve Kappa istatistikleri kullanıldı. Sonuçlar: Geçtiğimiz 12 aydaki düşme deneyimlerini (κ=0,564) ve tökezlemeleri (κ=0,551) değerlendiren sorular orta düzeyde uyum gösterirken, iç mekanda düşmelerin yeri (κ=0,848) ve tökezleme durumlarını (κ=0,801) değerlendiren sorular güçlü uyum gösterdi. Kapalı alanda (0,957) ve açık alanda (0,939) düşme sayısı için ICC değerleri güçlü bir uyum gösterirken, kapalı alanda (0,987) ve açık alanda (0,993) tökezleme sayısı için ICC değerleri de güçlü bir uyum gösterdi. Tartışma: PDF-Q'nun Türkçe uyarlaması, PD'li bireylerde düşme geçmişini ve koşullarını değerlendirmek için güvenilir bir araçtır. Bu doğrulanmış anket, klinik ortamlarda ve araştırmalarda düşme riskini değerlendirmek ve Türk PD hastaları için özel olarak tasarlanmış önleyici stratejiler geliştirmek için etkili bir şekilde kullanılabilir.
